Abstract:
The status of whitebark pine (Pinus albicaulis), a foundation and keystone species and a pioneer establisher at alpine treeline, is threatened by the invasive and exotic fungal pathogen (Cronartium ribicola) that causes white pine blister rust in five-needled pines. Originally thought to be limited to moderate environments, the disease is now found extensively throughout colder and dryer regions east of the Continental Divide, including alpine treeline. My research objective was to determine how blister rust infection of treeline whitebark pine varies across Glacier National Park. I present findings from field sampling conducted in July 2008 in Glacier National Park, Montana. Thirty plots were randomly placed at 6 different treeline study sites on the eastern slopes of the Continental Divide. Vegetative and geomorphic characteristics, along with presence/absence and level of blister rust intensity, were detailed within each plot. Vegetation measurements included conifer composition, tree island dimensions and windward growth patterns, evidence and intensity of blister rust, as well as shelter type. Field-measured topographic characteristics included elevation, aspect, and slope. In addition, high resolution GPS-derived DEMs were created at each plot in order to model the land surface and calculate detailed environmental variables in a GIS. Environmental and blister rust intensity variables were used to determine spatial correlates of blister rust infection at treeline. The resulting blister rust prediction model (P < 0.001, F(4,25) = 6.79, R2 = 0.52, Adjusted R2 = 0.44) suggests that areas exhibiting increased wind speed, northwest facing slopes, high flow accumulation rates, and close proximity to perennial streams have a higher likelihood of blister rust intensity, specifically total canker density. Results of this research may contribute to the understanding of the dynamics of this disease, and prove useful in whitebark ecosystem management and conservation.

Abstract:
Whitebark pine is an important keystone and foundation species in western North American mountain ranges, and facilitates tree island development in Rocky Mountain treelines. The manifestation of white pine blister rust in the cold and dry treelines of the Rockies, and the subsequent infection and mortality of whitebark pines raises questions as to how these extreme environments harbor the invasive disease, and what the consequences may be for treeline dynamics. This dissertation research comprises three studies that investigate abiotic factors influential for blister rust infection in treeline whitebark pines, how disease coupled with changing climate may affect whitebark pine treeline dynamics, and the connection between treeline spatial patterns and disease. The first study examined the spatial variation of blister rust infection in two whitebark pine treeline communities, and potential topographic correlates. Using geospatial and field approaches to generate high resolution terrain models of treeline landscapes, microtopography associated with solar radiation and moisture were found most influential to blister rust infection in treeline whitebark pines. Using field-based observations from sampled treeline communities, the second study developed an agent-based model to examine the effects of disease and climate on treeline pattern and process. Treeline dynamics were simulated under five hypothetical scenarios to assess changes in tree spatial patterns and populations. Blister rust-induced loss of whitebark pines resulted in a decline of facilitative processes, and an overall negative treeline response to disease—despite the beneficial effects of climate amelioration. The objective of the third study was to explore whether spatial patterns of tree proximity, size, and growth infer disease patterns. Comparing spatial patterns of tree characteristics between diseased and undiseased treeline communities, I found that trees growing near trees with larger stem diameters, and larger tree islands, tended to have more blister rust cankers, and displayed clustered spatial patterns. Undiseased treeline patterns revealed near neighbors smaller in stem diameter and tree island size, and were randomly dispersed. Blister rust diseased whitebark pines reveal spatial autocorrelation, despite the complex blister rust disease life cycle. Overall, findings from this dissertation reveal the implications of invasive disease on sensitive treeline ecotones dependent on a keystone species.

Abstract:
This thesis is focused on the issue of computational modeling of soil harvesting while using the compact excavator from the company DOOSAN BOBCAT EMEA s.r.o.. The solution consists in creating two computational models in Rocky DEM and Ansys Mechanical. Rocky DEM software is used to solve the disconnection of soil by excavator components using the discrete element method. The outcome includes courses of forces and moments during the particular time of the individual joints of the model that was used. The obtained courses are then applied as an external load to the joint of a selected structural part of the analyzed model using a kinematic model in ANSYS Mechanical. The kinematic model consists of simplified geometry models of individual parts of the excavator arm, and a more detailed geometry model of the analyzed part of the arm. All the parts are connected to each other by rotational bonds representing joints. A static structural analysis of the mechanical stress is performed in ANSYS Mechanical for the prepared model during the simulated process. Finally, the selected structural part is assessed with respect to the elastic limit and fatigue strength.

Abstract:
The Zagros fold-thrust belt results from the continent-continent collision between the Arabian margin and the Eurasian plate following the closure of the Neo-Tethys Ocean during the Tertiary. Despite some ongoing controversies about the timing of the onset of the collision there is little doubt that the main episode of the cover shortening in the Zagros folded belt occurred since about 10 Ma as suggested by the youngest folded strata of the Agha Jari red marls. Shortening by about 70 km derived from balanced sections across the Zagros folded belt, yields shortening rates of 7 km Ma-1 consistent with the present-day rates of 0.7 cm yr-1 based on GPS studies. A major unconformity between the Agha Jari formation and the Bakhtyari conglomerates indicates that cover shortening decreased or ceased 5 Ma ago. During or since the deposition of the Bakhtyari Formation, the Zagros fold belt underwent a regional uplift whose origin still remains enigmatic. The deformation is characterized by periodic folding with axial lengths sometimes greater than 200 km. This fold geometry is outlined by the limestone beds of the Asmari Formation, which is one of the main oil reservoirs in the Zagros. The Zagros also serves as the main originating headspring of the rivers running into the Persian Gulf and Oman Sea watersheds. Among all these rivers, the major ones are: Arvand Rud, Gamasb, Karun, Rajah, Zaal and Marun join and form Jarahi, Seymareh, Qareh Aqhaj, Zohreh, Dalaki, Mend, Shur, Minab, Mehran and Naband. Therefore, the Zagros region has high potential for dam construction to control surface water for electric energy, water supply for irrigation of agricultural lands and land reclamation. Among various formations in the Zagros region, the Asmari Formation limestone with relatively exclusive characteristics such as rigidity and morphology is a suitable rock foundation for dams in the Zagros range. It should be considered that the Asmari limestones constitute a series of double plunging, asymmetrical folds with northwest-southeast trend and that the southern flanks are steeper than the north-eastern ones (70° to 90º, locally reversed). Due to varying inclinations, there are much more curvatures of strata in the southwestern flanks of folded structures, with different characteristics of the rock mass in the two flanks of the anticlines. The anticlines, particularly in the Asmari Formation, contain tension-induced, open fracturing which has introduced significant secondary permeability. Engineering geological investigations indicate that there is a clear relationship between rock mass characteristics of the Asmari Formation and tectonic activities such as various tilting and curvature rates of strata at folded structures in the Zagros Mountain range. In this regard it should be considered that the upper and middle units of the Asmari Formation that constituted the main dam foundation rock mass on the northern flanks are influenced by karstification processes which have resulted from aggressive mineral waters. Thus huge karst features and cavities can be observed, where the Gachsaran evaporites stratigraphically overlie Asmari Formation succession limestones. The aggressive mineral waters originating from the Gachsaran Formation play the main role in karstification of the Asmari Formation limestones, whereas the lower Asmari is less influenced by these solutions and karstification processes as it is restricted to where the Karun-3 and Karun-4 dams are situated. Reassessment of available data and geological investigations during this research, lead to a new proposed configuration of engineering characterization of the rock mass for the Asmari formation limestones in the Zagros Region.

Abstract:
River blockages formed by rock avalanches appear to pose a higher hazard potential than other landslide dams, given the extreme run-out distances and volumes of rock avalanche deposits. Recent research has identified rock avalanche deposits to have internal sedimentology consisting of a coarse surficial material (carapace) and a finer fragmented interior (body) potentially of critical importance to rock-avalanche dam stability. Physical scale modelling of overtopping failure and breach development in rock avalanche dams was used to quantify the influence of this sedimentology on critical breach parameters, and their prediction using existing embankment dam breach technologies. Results from this study indicate that the time to failure for rock avalanche dams is approximately twice that observed for homogeneous dams due to the armouring properties of the carapace; and that peak discharge is not significantly affected by sedimentology. While application of empirical, parametric, dimensional and physically based models indicated that uncertainty associated with predicted dam break discharges could range from ±19% to ±107%, no modelling technique was able to simulate the armouring phenomenon adequately. Comparison of actual and simulated breach evolution shows linear assumptions of breach depth and width development (as observed in homogeneous dams) to be incorrect. In the context of hazard management, the results suggest that empirical regression relationships should be used for rapid assessment of potential dam break flood magnitude.

Abstract:
El tema de esta investigación es la definición ideológica del rock cristiano. En la discusión de las características “cristianas” o “mundanas” que generalmente se presenta entre los creyentes cristianos, suele percibirse cierto juego de franquicias ideológicas que tienen el propósito de recuperar los aspectos más relevantes para una adecuada reproducción social y/o cultural de la institución religiosa. En este sentido, el propósito nuestro es el conocimiento etnográfico de la definición ideológica del rock cristiano. Para esto, se ha optado por la utilización de una perspectiva interpretativa de la subjetividad en el rockero cristiano. Interpretación que se define teóricamente mediante las pautas epistemológicas propuestas por el antropólogo norteamericano Clifford Geertz. Así, pues, el objetivo principal está dirigido al conocimiento interpretativo del significado, que se entiende como la representación simbólica que el objeto asume en la subjetividad de los rockeros cristianos; pero, también, de la función, o sea, al empleo que se promueve del mismo objeto entre aquellos. De esta manera, la definición ideológica del rock cristiano se descubre en la explicación exegética que se tiene de su significado y/o función religiosa. Para el análisis de este objetivo, se ha visto por conveniente la consideración de un esquema de clasificación etnomusicológico que —así como fue postulado por Alan P. Merriam— debe enfocarse en la representación que la música tiene para un determinado grupo social y/o cultural. En este sentido, los objetivos secundarios están establecidos en los siguientes aspectos temáticos: a. instrumentos musicales; b. lírica de las canciones; c. clasificación de la música; d. papel y categoría de los músicos; e. utilización de la música; f. creatividad artística. La metodología está basada en la etnografía, o sea, en el trabajo de campo antropológico, es decir, en la convivencia del investigador con los sujetos de estudio, refiriendo los aspectos que hacen a su propia cultura. En este sentido, las técnicas que constituyen a la etnografía están basadas en la observación, o sea, el examen del tiempo y/o espacio de los sujetos de estudio, y la entrevista, es decir, el conocimiento de los pensamientos sociales y/o culturales de los sujetos de estudio. Esta metodología se ha efectuado entre los miembros de la Congregación Cristiana Vida Nueva, que funciona en la ciudad de La Paz, zona de Villa Fátima, avenida Tejada Sorzano, nº 532. Concretamente, las técnicas etnográficas han sido aplicadas al “ministerio de alabanza y adoración” de esta congregación pentecostalista. Por su parte, las entrevistas personales se han realizado mayoritariamente entre los músicos cristianos del grupo Ciudad de Dios. En conclusión se afirma que la definición ideológica del rock cristiano se efectúa en el acuerdo íntimo o “comunión de santidad” que los creyentes cristianos tienen con Dios; pero, también, en relación con la utilidad práctica que esta clase de música cristiana ofrece para la evangelización y/o adoración pentecostalistas, principalmente

Full text
Abstract:
This thesis presents a systematic numerical modeling framework to simulate the stress-deformation and coupled stress-deformation-flow processes by performing uniaxial and biaxial compressive tests on fractured rock models with considering the effects of different loading conditions, different loading directions (anisotropy), and coupled hydro-mechanical processes for evaluating strength and deformability behavior of fractured rocks. By using code UDEC of discrete element method (DEM), a series of numerical experiments were conducted on discrete fracture network models (DFN) at an established representative elementary volume (REV), based on realistic geometrical and mechanical data of fracture systems from field mapping at Sellafield, UK. The results were used to estimate the equivalent Young’s modulus and Poisson’s ratio and to fit the Mohr-Coulomb and Hoek-Brown failure criteria, represented by equivalent material properties defining these two criteria. The results demonstrate that strength and deformation parameters of fractured rocks are dependent on confining pressures, loading directions, water pressure, and mechanical and hydraulic boundary conditions. Fractured rocks behave nonlinearly, represented by their elasto-plastic behavior with a strain hardening trend. Fluid flow analysis in fractured rocks under hydro-mechanical loading conditions show an important impact of water pressure on the strength and deformability parameters of fractured rocks, due to the effective stress phenomenon, but the values of stress and strength reduction may or may not equal to the magnitude of water pressure, due to the influence of fracture system complexity. Stochastic analysis indicates that the strength and deformation properties of fractured rocks have ranges of values instead of fixed values, hence such analyses should be considered especially in cases where there is significant scatter in the rock and fracture parameters. These scientific achievements can improve our understanding of fractured rocks’ hydro-mechanical behavior and are useful for the design of large-scale in-situ experiments with large volumes of fractured rocks, considering coupled stress-deformation-flow processes in engineering practice.

Abstract:
Le comportement mécanique en cisaillement sous contrainte normale constante de joints rocheux est étudié en utilisant une approche numérique par éléments discrets (DEM Discrete Element Model). Les influences respectives de la rugosité des surfaces des joints, de l'élasticité des épontes, de la rupture des aspérités de surface et du niveau de contrainte de compression sur les comportements en fermeture et cisaillement des joints rocheux sont particulièrement analysées. Pour la première fois la rugosité des joints considérée comme auto-affine est utilisée avec DEM pour étudier le frottement des joints rocheux. Cette rugosité est décrite par l’intermédiaire de trois paramètres :exposant de rugosité auto-affine, longueur de corrélation auto-affine et variance des fluctuations de hauteur. Sur la base d’un algorithme fondé sur la méthode spectrale, huit surfaces auto-affines isotropes correspondant à différentes rugosités ont été générées. Ces surfaces numériques sont utilisées comme moules permettant de générer les surfaces composées d’éléments discrets utilisées dans la suite de l’étude. La modélisation par éléments discrets s’appuie sur une calibration des propriétés élastiques effectuée à partir d’un volume élémentaire représentatif suivie de l’implémentation d’un critère elliptique de contraintes de rupture (au niveau des lois d’union entre éléments) permettant de simuler les grandes lignes du comportement quasi-fragile d’un mortier(utilisé lors d’expérimentations antérieures). Sur cette base et une fois les surfaces rugueuses implémentées dans les modèles DEM, les essais de fermeture (test de compression) des huit joints sont effectués sous deux niveaux de contrainte de compression : 14 MPa et 21 MPa. Par la suite, les joints sont cisaillés selon deux directions perpendiculaires. Pour chaque direction de cisaillement et chaque niveau de contrainte de compression, les joints sont testés en utilisant trois modèles mécaniques différents : 1) modèle rigide dans lequel, à l’exception des surfaces de joint en contact,les épontes ne peuvent pas se déformer, 2) modèle élastique dans lequel les épontes peuvent se déformer dans leur volume et 3) modèle élastique-fracture dans lequel les épontes peuvent se déformer dans leur volume et les liens entre les particules peuvent rompre selon le critère elliptique de contrainte. L'utilisation de ces trois modèles mécaniques différents permet d'étudier de façon systématique l'influence de la rugosité seule (modèle rigide), l'influence de l'élasticité et de la rugosité (modèle élastique) et enfin, l'effet combiné de la rugosité, de l'élasticité et de la rupture(modèle élastique-fracture). L’étude des résultats obtenus lors des simulations DEM est accompagnée d’une analyse énergétique permettant d’estimer l’évolution de l’énergie élastique stockée dans le système, de l’énergie de friction, du travail associé à la dilatance du joint et de l’énergie dissipée au cours de l’essai de cisaillement
The shear behavior of rock joints under constant normal stress is studied using Discrete Element Method (DEM). The respective influences of joint surface roughness, elasticity of medium, fracture of surface asperities, and level of compression load on the closure and shear behaviors of rock joints are particularly analyzed. For the first time the roughness of the joints considered as self-affine is use dwith DEM to study the friction of rock joints, the roughness is described through three parameters:self-affine roughness exponent, self-affine correlation length and height variance. Using a numerical algorithm based on spectral method, eight isotropic self-affine surfaces corresponding to different roughness are generated. Latter, numerical surfaces are used as molds to generate the discrete elements surfaces. The discrete element modeling is premised on a preliminary calibration of the elastic properties performed on a representative elementary volume and on the implementation of the fracture properties (elliptic fracture criterion expressed in stress) describing with a reasonable accuracy the quasi-brittle fracture behavior of mortar (used in previous experimental tests). On this basis and once the roughness surfaces implemented in DEM, the simulations of the compression/closure test are performed on the eight joints and this for two compression stress levels: 14 MPa and 21 MPa. Then, the eight DEM joints are sheared along two perpendicular directions. For each shear direction and each level of compression stress, the joints are tested through three different mechanical models: 1) rigid model in which the medium cannot deform excepted at the contact surface of joints, 2) elastic model in which the medium can deform in its volume and 3) elastic-fracture model in which the medium can deform in its volume and the bondsbetween discrete elements can failed according to the elliptic fracture criterion. The use of these three mechanical models allows studying systematically the influence of the roughness alone (rigidmodel), the influence of elasticity and roughness (elastic model) and finally, the combined effect ofthe joint roughness, of the elasticity and of the fracture (elastic-fracture model). The study of the results obtained from the DEM simulations is followed by an energetic analysis allowing theestimation of the evolutions, as a function of the shear displacement, of the elastic energy stored inthe system, of the friction energy, of the work related to the joint dilatancy and of the energy dissipated by internal damping of the DEM
En esta tesis se estudia la fricción en juntas rocosas utilizando el Método de Elementos Discretos (DEM). En particular, se estudia la influencia de la rugosidad de las superficies de la junta, la elasticidad, la fractura, y el nivel de carga de compresión sobre el comportamiento de cierre y de cizalla de las juntas rocosas. Por primera vez la rugosidad de las juntas considerada como auto-afín esutilizada para estudiar la fricción de juntas rocosas, la rugosidad se describe mediante tres parámetros: el exponente de rugosidad, la longitud de correlación auto-afín y la varianza de alturas. Mediante un algoritmo de computadora basado en métodos espectrales, ocho superficies autoafines isotrópicas con diferente rugosidad fueron creadas. Posteriormente, las ocho superficies fueron utilizadas como moldes para generar las juntas utilizando elementos discretos. Antes de realizar las simulaciones de compresión y cizallaura, se calibraron las propiedades elásticas y defractura (criterio de fractura elíptico basado en esfuerzos) de las juntas numéricas a los datos experimentales (obtenidos previamente) de unas muestras de mortero mediante la utilización de un volumen elemental representativo (REV). Una vez que las propiedades mecánicas de las juntas se obtuvieron mediante la calibración del REV, se realizaron las pruebas de cierre (prueba de compresión) de las ocho juntas DEM. Se utilizaron dos niveles de esfuerzo de compresión para laspruebas de cierre: 14 MPa y 21 MPa. Después, las ocho juntas DEM fueron cizalladas en dos direcciones mutuamente perpendiculares. Para cada dirección de cizalla y cada nivel de esfuerzo decompresión (14 y 21 MPa), las juntas fueron cizalladas usando uno de los tres modelos mecánicos siguientes: 1) un modelo rígido, en el que las juntas no se pueden deformar, excepto en su superficie,2) un modelo puramente elástico, en el que las juntas se pueden deformar en todo su volumen y 3)un modelo elástico con fractura en el que las juntas se pueden deformar en su volumen y, si elesfuerzo sobre las uniones entre partículas excede cierto nivel de esfuerzo máximo, las uniones se rompen de una manera irreversible. El uso de estos tres modelos mecánicos nos permitirá estudiar de manera sistemática: la influencia de la rugosidad (modelo rígido), la influencia de la elasticidad y rugosidad (modelo puramente elástico) y, finalmente, el efecto combinado de la rugosidad de las juntas, la elasticidad y la fractura (modelo elástico con fractura). El estudio de los resultados obtenidos de las simulaciones DEM es seguido por una análisis energético el cual permite estudiar la evolución de los diferentes tipos de energía en función del desplazamiento de cizalla: energía elástica almacenada en el sistema, energía de fricción entre elementos discretos, el trabajo relacionado conla dilatación de la junta y la energía disipada por el amortiguamiento interno del DEM

L’objectif de cette étude est d’affiner notre compréhension de la distribution des hétérogénéités de concentration de la matière organique dans les roches mères en se basant sur des affleurements et des données de puits provenant des Formations Triasiques de Montney et Doig (Canada). La méthodologie développée dans cette étude est la suivante : (1) la corrélation de forages sur les principes de la stratigraphie séquentielles, (2) l’analyse d’échantillons prélevés sur des affleurements, des carottes et des débris de forages avec un Rock-Eval, un ICP-MS/AES (3) l’intégration des résultats des analyses géochimiques et pétrographiques dans le cadre stratigraphique, (4) l’utilisation du code numérique DIONISOS pour restaurer l’architecture stratigraphique des Formations de Montney et Doig et tester plusieurs scénarios de productivité primaire et de restriction du bassin.Les formations de Montney et Doig ont été découpées en quatre séquences elles-mêmes regroupées en deux cycles de second ordre (A et B) séparés par un hiatus majeurs. Cette étude montre que les formations triasiques de l’Ouest du Canada se sont déposées dans un bassin actif et non pas sur une marge passive. L’intégration des résultats des analyses géochimiques et pétrographiques dans le cadre stratigraphique fait ressortir deux niveaux d’accumulation de la matière organique : une dans le FSST de la séquence A et une dans le TST de la séquence B. La modélisation avec DIONISOS montre un effondrement majeur des apports sédimentaires entre le Trias inférieur et moyen. Dernièrement, cette étude met en avant le contrôle de premier ordre de l’évolution géodynamique sur l’accumulation de la matière organique
The aim of this study is to improve the understanding of sedimentary organic matter heterogeneities in unconventional plays, based on outcrop and well data from the Triassic Montney and Doig Formations. The workflow comprises four steps: (1) well correlations, based on sequence stratigraphy, (2) Rock-Eval VI and ICP-MS/AES analyses of outcrop, core and cutting samples, (3) integration of the analyses results in the stratigraphic framework, (4) a process-based forward modeling of the stratigraphic evolution of the basin with DIONISOS in order to test multiple scenarios of primary productivity and basin restriction.The stratigraphic architecture of the Montney and Doig Fms has been subdivided into four sequences gathered in two second order cycles (A and B) separated by a major time gap (approx. 2 My). This study shows that the deposition of the Triassic series on the Western margin of North America took place in an active structural context and not on a passive margin. The integration of the geochemical and petrographic analyses results in the stratigraphic framework shows that significant organic accumulations are located in the FSST of sequence A and in the TST of sequence B. DIONISOS shows a major drop of the sedimentary inputs between Lower and Middle Triassic that is interpreted to be linked to the regional geodynamic evolution and the early stages of the Canadian Cordillera orogeny. Lastly, this study emphasizes the first order control of the geodynamic evolution on organic rich accumulation

Abstract:
Two new three-dimensional rock mass strength criteria are developed in this dissertation by extending an existing rock mass strength criterion. These criteria incorporate the effects of the intermediate principal stress, minimum principal stress and the anisotropy resulting from these stresses acting on the fracture system. In addition, these criteria have the capability of capturing the anisotropic and scale dependent behavior of the jointed rock mass strength by incorporating the effect of fracture geometry through the fracture tensor components. Another significant feature of the new rock mass strength criterion which has the exponential functions (equation 6.7) is having only four empirical coefficients compared to the existing strength criterion which has five empirical coefficients; if the joint sets have the same isotropic mechanical behavior, the number of the empirical coefficients reduces to two in this new strength criterion (equation 6.10). The new criteria were proposed after analyzing 452 numerical modeling results of the triaxial, polyaxial and biaxial compression tests conducted on the jointed rock blocks having one or two joint sets by the PFC3D software version 5. In this research to have several samples with the same properties a synthetic rock material that is made out of a mixture of gypsum, sand and water was used. In total, 20 joint systems were chosen and joint sets have different dip angles varying from 15 to 60 at an interval of 15 with dip directions of 30 and 75 for the two joint sets. Each joint set also has 3 persistent joints with the joint spacing of 42 mm in a cubic sample of size 160 mm and the joints have the same isotropic mechanical behavior. The confining stress combination values were chosen based on the uniaxial compressive strength (UCS) value of the modeled intact synthetic rock. The minimum principal stress values were chosen as 0, 20, 40 and 60 percent of the UCS. For each minimum principal stress value, the intermediate principal stress value varies starting at the minimum principal stress value and increasing at an interval of 20 percent of the UCS until it is lower than the strength of the sample under the biaxial loading condition with the same minimum principal stress value. The new rock mass failure criteria were developed from the PFC3D modeling data. However, since the joint sets having the dip angle of 60 intersect the top and bottom boundaries of the sample simultaneously, the joint systems with at least one of the joint sets having the dip angle of 60 were removed from the database. Thus, 284 data points from 12 joint systems were used to find the best values of the empirical coefficients for the new rock mass strength criteria. λ, p and q were found to be 0.675, 3.16 and 0.6, respectively, through a conducted grid analysis with a high R2 (coefficient of determination) value of 0.94 for the new criterion given by equation 6.9 and a and b were found to be 0.404 and 0.972, respectively, through a conducted grid analysis with a high R2 value of 0.92 for the new criterion given by equation 6.10. The research results clearly illustrate how increase of the minimum and intermediate principal stresses and decrease of the joint dip angle, increase the jointed rock block strength. This dissertation also illustrates how different confining stress combinations and joint set dip angles result in different jointed rock mass failure modes such as sliding on the joints, failure through the intact rock and a combination of the intact rock and joint failures. To express the new rock mass strength failure criteria, it was necessary to determine the intact rock strengths under the same confining stress combinations mentioned earlier. Therefore, the intact rock was also modeled for all three compression tests and the intact rock strengths were found for 33 different confining stress combinations. Suitability of six major intact rock failure criteria: Mohr-Coulomb, Hoek-Brown, Modified Lade, Modified Wiebols and Cook, Mogi and Drucker-Prager in representing the intact rock strength was examined through fitting them using the aforementioned 33 PFC3D data points. Among these criteria, Modified Lade, Modified Mogi with power function and Modified Wiebols and Cook were found to be the best failure criteria producing lower Root Mean Square Error (RMSE) values of 0.272, 0.301 and 0.307, respectively. Thus, these three failure criteria are recommended for the prediction of the intact rock strength under the polyaxial stress condition. In PFC unlike the other methods, macro mechanical parameters are not directly used in the model and micro mechanical parameter values applicable between the particles should be calibrated using the macro mechanical properties. Accurate calibration is a difficult or challenging task. This dissertation emphasized the importance of studying the effects of all micro parameter values on the macro mechanical properties before one goes through calibration of the micro parameters in PFC modeling. Important effects of two micro parameters, which have received very little attention, the particle size distribution and the cov of the normal and shear strengths, on the macro properties are clearly illustrated before conducting the said calibration. The intact rock macro mechanical parameter values for the Young’s modulus, uniaxial compression strength (UCS), internal friction angle, cohesion and Poisson's ratio were found by performing 3 uniaxial tests, 3 triaxial tests and 5 Brazilian tests on a synthetic material made out of a mixture of gypsum, sand and water and the joint macro mechanical parameter values were found by conducting 4 uniaxial compression tests and 4 direct shear tests on jointed synthetic rocks with a horizontal joint. Then the micro mechanical properties of the Linear Parallel Bond Model (LPMB) and Modified Smooth Joint Contact Model (MSJCM) were calibrated to represent the intact rock and joints respectively, through the specific procedures explained in this research. The similar results obtained between the 2 polyaxial experiments tests of the intact rock and 11 polyaxial experimental tests of the jointed rock blocks having one joint set and the numerical modeling verified the calibrated micro mechanical properties and further modification of these properties was not necessary. This dissertation also proposes a modification to the Smooth Joint Contact Model (SJCM) to overcome the shortcoming of the SJCM to capture the non-linear behavior of the joint closure varying with the joint normal stress. Modified Smooth Joint Contact Model (MSJCM) uses a linear relation between the joint normal stiffness and the normal contact stress to model the non-linear relation between the joint normal deformation and the joint normal stress observed in the compression joint normal stiffness test. A good agreement obtained between the results from the experimental tests and the numerical modeling of the compression joint normal test shows the accuracy of this new model. Moreover, another shortcoming associated with the SJCM application known as the interlocking problem was solved through this research by proposing a new joint contact implementation algorithm called joint sides checking (JSC) approach. The interlocking problem occurs due to a shortcoming of the updating procedure in the PFC software related to the contact conditions of the particles that lie around the intended joint plane during high shear displacements. This problem increases the joint strength and dilation angle and creates unwanted fractures around the intended joint plane.

Abstract:
High pressure grinding rolls (HPGR) are becoming an increasingly popular energy efficient solution for comminution of hard rock ores. A significant barrier to the increased adaptation of HPGRs is the current requirement for large amounts of sample for pilot testing. The primary objective of the research was to develop a DEM based computer model for an HPGR to analyze the particle behavior in the unit and to predict its sizing information. EDEM, a DEM based software, was used to model the pilot scale HPGR unit and single particle compression test was used to evaluate the particle breakage and then used as an input parameter for the simulations. The results obtained from the simulation were then validated with the results from the pilot scale tests. Results obtained from the simulation suggested that a DEM-based model can be used to identify the pressure/force distribution profile for an HPGR roll surface that can then be used to design the appropriate piston geometry to match the HPGR pressure profile. Also, the developed HPGR model was used to estimate the critical sizing information for certain samples and machine operating conditions. The model generated similar trends as the pilot scale test with a lower magnitude of m-dot and specific energy consumption primarily due to the absence of a packed particle bed. The HPGR model, combined with powerful computers and larger sample masses for simulation, can be used as a procedure to size and select an industrial HPGR unit and to analyze the equipment behavior under various operating conditions and feed characteristics.

Abstract:
Les argilites, sont définies comme étant des roches comportant une large fraction de minéraux argileux. Leurs propriétés physiques et mécaniques présentent un intérêt pour l’étude du comportement hydro-mécanique des failles dans la partie supérieure de la croûte mais aussi pour la compréhension des roches couvertures de réservoirs d’hydrocarbures ou pour l’expertise de la pérennité du stockage de déchets radioactifs.Cette thèse propose deux approches afin de comprendre l’organisation de la déformation dans ce type de matériau, une première purement mécanique sur des échantillons intacts et la seconde s’intéressant aux propriétés physiques de matériaux déformés. Pour cela, nous avons étudié les argilites de Tournemire (Tunnel expérimental de l'IRSN, Aveyron, France).La première partie consiste en une série d’essais triaxiaux. Nous avons déterminé les enveloppes de rupture de trois groupes d’échantillons carottés avec des orientations différentes par rapport au litage (0°, 45°, et 90°). Pour chaque orientation, sept expériences ont été réalisées à différentes pressions de confinement (2.5, 5, 10, 20, 40, 80, 160 MPa). L’influence de la vitesse de déformation a été établie en comparant des expériences réalisées avec des vitesses de déformation différentes (10-7 s-1 et 10-5 s-1). Pendant les expériences, les vitesses d’ondes P et S ont été enregistrées selon différents angles par rapport au litage afin de quantifier l’évolution de l’anisotropie des propriétés élastiques.Cette partie permet de mettre en évidence l’importance de l’orientation du litage par rapport à la contrainte principale sur la résistance mécanique de nos échantillons. De plus, un modèle micromécanique basé sur le « wing crack » permet d’expliquer l’anisotropie mécanique de nos argilites par l’anisotropie de la ténacité KIC.Par ailleurs, on constate que l’évolution de l’anisotropie des propriétés élastiques dépend elle aussi de l’orientation considérée. Lors de la compression, l’orientation 90° présente d’importantes variations pouvant aller jusqu’à une inversion de l’anisotropie, alors que les vitesses n’évoluent que très peu pour l’orientation 0°. Ces variations ont été quantifiées par les paramètres de Thomsen. L’étude des vitesses élastiques et celle des microstructures, permettent de mettre en évidence l’importance des processus plastiques comme la réorientation des minéraux au cours de la déformation.La seconde partie consiste en une étude pétrophysique (vitesses des ondes P, ASM, densité, saturation, porosité) d’échantillons provenant d’un forage traversant une zone de faille. Le but est de quantifier la variation de ces propriétés à l’approche du cœur de faille.Un protocole d’échantillonnage et de mesure a été mis en place. Le protocole comporte une première série de mesures directement sur le terrain afin de s’affranchir des problématiques liées à la préservation des échantillons (notamment pour les mesures de porosité/densité/saturation). Par la suite, des échantillons ont été prélevés pour réaliser des mesures à la fois dans le cadre de cette thèse (vitesses des ondes P et ASM) mais aussi dans d’autres laboratoires (étude de la composition minéralogique, CT-scan).A partir des observations, on caractérise :• Une zone saine caractérisée par des échantillons ne présentant pas ou très peu de fracturation• Une zone endommagée qui présente un grand nombre de fractures calcifiées• Une zone de cœur caractérisée par une déstructuration totale (pas de bedding apparent) et des variations de couleur.Notre étude met en évidence une signature physique propre à chaque zone de cette faille avec notamment une diminution de l’anisotropie des échantillons en zone endommagée fortement marquée. De plus, des mécanismes de rotation de la stratigraphie similaires à ceux observés à l’échelle des microstructures lors de la déformation expérimentale ont été observés
Shales or clays are defined as rock having a large proportion of clay minerals. Their physical and mechanical properties are of interest for the study of the hydro-mechanical behavior of faults in the uppermost crust but also for the understanding of the cap rocks of hydrocarbon reservoirs or for the expertise of the durability of radioactive waste storage.This thesis proposes two complementary approaches to understand the organization of the deformation in this type of material, a first purely mechanical on undisturbed samples and the second focusing on the physical properties of deformed materials. During this thesis, we studied Tournemire shales (IRSN tunnel, Aveyron, France).The first part consists in triaxial tests. We determined the failure envelopes of three sets of core samples with different orientations with respect to bedding (0 °, 45 ° and 90 °). For each orientation, seven experiments were performed at different confining pressures (2.5, 5, 10, 20, 40, 80, 160 MPa). The influence of the strain rate was determined by comparing experiments with different strain rates extending over two orders of magnitude (between 〖10〗^(-7) s^(-1) and 〖10〗^(-5) s^(-1)). During the experiments, the P and S wave velocities were recorded from different angles with respect to the bedding to quantify the evolution of the anisotropy of the elastic properties according to the imposed stress.This section allows to highlight the importance of the orientation of bedding relatively to the principal stress applied on our samples. It is noted for example that the weakest orientation is 45 ° and 90 ° the strongest orientation. In addition, a micromechanical model based on the "wing crack" theory helps to explain the mechanical anisotropy of our argillites by the anisotropy of the fracture toughness K_Ic.Moreover, it is found that changes in the anisotropy of the elastic properties also depends on the bedding orientation. During compression, the 90 ° orientation has significant variations up to a reversal of the anisotropy, whereas the elastic wave velocities show little changes for 0 ° orientation. These variations were quantified by Thomsen parameters. The study of elastic velocities and of microstructures of our samples highlight the importance of the plastic processes such as reorientation of minerals during deformation.The second part consists of a petrophysical study (P wave velocities, ASM, density, saturation, porosity) of samples from a borehole drilled through a fault zone. The goal here is to quantify the variation of these properties as we approach the fault core.A protocol of sampling and measurement was established to realize a complete study of drillings. The protocol includes a first serie of measures directly in the field in order to overcome the problems linked to the preservation of samples (especially for porosity measurements / density / saturation). Subsequently, samples were taken for measurements both in the context of this thesis (P wave velocities and ASM), but also in other laboratories (study of the mineralogical composition, CT-scan).Three fault zones were identified from field observations:• An intact zone characterized by samples with no or very little fracturing• A damaged zone that includes a large number of calcified fractures• A fault core zone characterized by a complete breakdown (no apparent bedding) and color variations.Although these areas were determined on observation criteria, our study demonstrates an own physical signature for each zone of this fault with an important decrease in the anisotropy of the samples from fault core. In addition, bedding rotation with similar mechanisms to those observed at the microstructural scale during the experimental deformation was observed

La stabilité des excavations dans les roches fracturées est influencée, entre autres, par le régime structural, qui est inhérent à la roche. Divers outils sont disponibles pour les analyses de stabilité, mais la qualité des résultats dépend considérablement des données d’entrée disponibles et des outils utilisés. Dans ce mémoire, deux études de cas sont présentées, qui étudient l'influence de la représentation de données structurales sur l'analyse de stabilité. La première étude de cas traite de la stabilité d'une pente de roche le long d'une route près de Fleurimont, qui a subi des effondrements de dièdre. L’objectif était de découvrir si les effondrements pourraient avoir été prédits et d'évaluer la probabilité de la rupture de dièdre le long de la pente. Plusieurs analyses d'équilibre limite ont été effectuées, y compris une analyse déterministe rétrospective de deux ruptures de dièdres, et une analyse probabiliste des dièdres individuels. De plus, une analyse probabiliste de système de joints a été effectuée en utilisant les modèles 3D de système de joints, qui ont été générés avec des données de terrain. Les données nécessaires pour les analyses ont été recueillies sur place. Les résultats d’analyse rétrospective ont indiqué l'instabilité potentielle des dièdres observés, et les approches probabilistes ont confirmé l'occurrence des effondrements de dièdre le long de la pente, mais ils ont également démontré que la probabilité d'effondrements semblables est faible. Les résultats ont démontré qu'une analyse de données exhaustive en utilisant plusieurs outils d'analyse est requise pour obtenir une évaluation fiable du comportement de la roche. La deuxième étude de cas discute de la stabilité des galeries à la mine souterraine LaRonde de l'Agnico Eagle, qui sont concernées par de grandes déformations à cause de la convergence des parois. L'analyse de la convergence observée s'est concentrée sur la génération d'une série de modèles numériques 2D selon la méthode des éléments finis, visant à reproduire le mécanisme d'effondrement et les déformations résultantes. La foliation in situ a été reproduite par des joints, qui ont été introduits explicitement dans le modèle. Les données structurales requises ont été rassemblées sur place. Les modèles ont été calibrés avec les données de convergence disponibles. Les résultats de modélisation numérique ont atteint une bonne concordance avec les observations sur place. Les deux profils caractéristiques observés et l’ordre de grandeur des déformations mesurées ont pu être reproduits. Il a été démontré que le modèle numérique appliqué est un outil utile pour modéliser les conditions complexes observées à la mine.

The stability of excavations in fractured rock is influenced among others by the structural order inherent in the rock mass. Various analysis tools are available for stability analysis, but the quality of results depends considerably on the available analysis data and the tools used. In this thesis two case studies of excavations in fractured rock are presented that investigate the influence of structural data representation on the stability analysis. The first case study focused on the stability of a rock slope along a road cut near Fleurimont that has experienced wedge failures. The aim was to find out, if the failures could have been predicted, and to evaluate the probability of wedge failures along the slope. Different limit equilibrium wedge analyses were carried out, including a deterministic back-analysis of two wedge failures and a probabilistic analysis of individual wedges. Furthermore a probabilistic joint system analysis was carried out using 3D joint system models generated out of field data. As part of this work the required analysis data was collected on site. The back-analysis results suggested potential instability of the observed wedges, and the probabilistic approaches confirmed the occurrence of wedge failures along the slope, but also indicated the only low probability for these failures. The results demonstrated that a comprehensive data analysis using various analysis tools is required to reach a reliable assessment of the rock behaviour. The second case study discusses the stability of drifts at Agnico Eagle’s LaRonde underground mine that are affected by large deformations due to rock squeezing. The analysis of the observed drift convergence focused on the generation of a series of numerical 2D finite element models, aiming to reproduce failure mechanism and resulting deformations. The in situ foliation was reproduced by explicitly introducing joints into the model. The required structural data was collected on site. As reference data for the model calibration available convergence data was used. The modelling results reached a good agreement with the observations on site. Both observed characteristic deformation profiles as well as measured deformation magnitudes could be adequately reproduced. It could be demonstrated that the applied numerical model is a useful tool to model the complex squeezing ground conditions observed at the mine. More validation experiments should be carried out, but the method can potentially be used to develop better mine development strategies in similar conditions. Both case studies demonstrated the influence of structural data representation on the data analysis. Furthermore it could be shown that the choice of analysis tools influences the obtained results.

Abstract:
I mitt examensarbete har jag valt att utforska mer komplexa former inom komponerande av rockmusik, för att ta reda på: vilka metoder jag kan använda mig av för att undvika traditionella formmönster, vilka resultat jag kan få när jag använder mig av otypiska formmönster och hur upplevelsen av formdelars funktioner blir när man använder sig av otypiska formdelar. Min metod har varit att ha en egen utgångspunkt till varje låt, till exempel att inte ha några återkommande formdelar, för att kunna bryta de formmönster som jag i vanliga fall använder mig av. I det här arbetet beskriver jag om hur jag gått tillväga under den kreativa processen, och om vad formdelars funktioner kan uppfattas när använder sig av otypiska mönster. De fyra låtarna har spelats in i replokal och i studio. Genom min studie har jag lärt mig att lita på mina instinkter även fast jag inte vet exakt vad de innebär och att saker och ting inte behöver vara självklara från första början.

Abstract:
In questo lavoro vengono presentati i metodi ed i principali risultati ottenuti dall’inventario dei rock glaciers in Val Formazza, Piemonte. Il lavoro presenta la compilazione di un nuovo inventario dei rock glaciers sulla base di ortofoto e DSM, in ambiente QGIS. L’attività di fotointerpretazione di ortoimmagini aeree e rilievi ombreggiati viene integrata con l’utilizzo dell’applicazione QGIS che permette la mappatura e la determinazione dei principali attributi topografici e geomorfologici dei rock glaciers. Le informazioni contenute nel nuovo inventario integrano e aggiornano la mappatura già esistente dei rock glaciers in Val Formazza, svolta da Arpa Piemonte. I rock glaciers censiti nel vecchio inventario sono 27; con questa nuova mappatura se ne possono contare 115, di cui 23 sono stati classificati come intatti e 92 come relitti. Oltre al grado di attività, per ognuno dei rock glaciers mappati è stata descritta la forma (linguoidi, lobati o multilobo) e sono stati estratti l’area, l’esposizione e la quota minima, che corrisponde alla quota del fronte del rock glacier. I risultati mostrano che la maggior parte della Val Formazza è occupata da rock glaciers relitti. I rock glaciers relitti si trovano a quote inferiori (2000 m) rispetto a quelli intatti (2500 m). In termini di esposizione, non risultano esserci rock glaciers esposti a Nord, ma sono presenti sia a Nord-Ovest che a Nord-Est. Per quanto riguarda la distribuzione dei rock glaciers intatti non è stato trovato nessun rock glacier con classe di esposizione Est. Le quote più basse dei rock glaciers relitti sono esposte ad Est mentre le quote più alte si trovano ad Ovest. I rock glaciers intatti hanno un andamento simile ai relitti con esposizione ad Oriente per quanto riguarda le quote minori e in merito alle quote maggiori i rock glaciers intatti differiscono dai relitti e presentano quote più elevate a Sud e Sud-Ovest e a Nord-Ovest.

Full text
Abstract:
L'analyse développée dans cette thèse porte sur les processus de reconnaissance sociale des groupes de rock amateurs c'est à dire peu visibles et peu connus socialement. Ces groupes sont qualifiés de minorités rock par référence à la théorie de l'influence sociale de S. Moscovici (psychologie des minorités actives, paris, puf, 1979). Plus précisément, l'état acide désigne une expérience de la reconnaissance sociale des minorités anomiques. Les minorités rock sont dites anomiques parce qu'elles se forment dans le but de créer leur propre code et dépendent de la majorité pour leur visibilité sociale. Le code des minorités rock est donc à la fois intérieur et extérieur à elles. Il est à la fois un projet et un enjeu de reconnaissance sociale. L'état acide se manifeste: -par un état d'ambivalence sociale ou domine une indétermination dans la désignation des buts et du code d'une minorité; -par une expérience moderne de l'effervescence sociale c'est à dire de la socialisation d'une sensation (autant que d'un code) qui ne prend un sens qu'en devenant publique. L'état acide est un modèle théorique de la socialisation par la pratique d'un art de masse. Il rend compte de la transformation psycho-sociale qu'engendre le passage de l'état (ou situation) de consommateur même actif à celui de créateur de ses propres référents culturels. Les enquêtes effectuées portent sur des groupes de rock parisiens vivant dans le quatrième sous-sol d'un parking-automobiles. L'enquête par questionnaires (106 groupes) et l'observation-participante (44 entretiens de groupes) constituent l'essentiel du corpus d'analyse. Une enquête sur l'image des groupes de rock chez les lycéens de trois lycées parisiens (âges de 15 à 18 ans) complète le travail empirique. La thèse (1er volume, 532 pages) se divise en quatre parties: -l'état acide (construction théorique du modèle); -l'ombre des sous-sols (présentation du cadre de vie des minorités rock); -le fluide rock (représentations de la création et du rituel rock); -le mystère public (représentations de la destination du message rock et des publics). La partie annexe (2eme volume) comprend 405 pages
This work concerns the process of social recognition of rock groups whose social visibility is very limited. These groups are called rock minorities in reference to the theory of social influence developed by S. Moscovici (social influence and social change, London academic press, 1976). More precisely, acid state's model designates the anomic minorities’ experience of social recognition. The rock minorities are defined as anomic because they are formed in order to create their own code and they depend on majority in regards of their social recognition. So, their code is at the same time a project and a stake of social recognition, it is internal and external. The acid state is manifested: -by a state of social ambiguity (ambivalence) dominated by an indetermination of the minority's goals and code; -by a modern experience of the social effervescence (defined by Durkheim), that is to say a socialization of a sensation (as far as a code) who receives meaning by becoming public. The acid state is a theoretical model of the socialization by means of the practice of a mass art form. This model lightens the understanding of the process of the socio-psychological transformation resulting from the passage of the stage of consumer (even active consumer) to the situation of creator of its own norms. The empirical investigations were realized in a Parisian underground auto-park where rock groups live. A questionary inquiry (106 groups) and an ethnographic approach by collective interviews (44) form the biggest part of the data. The empirical research is completed by a questionary concerning the image of rock groups among Parisian high-school students. The thesis (first volume, 532 pages) is divided in four parts: -the acid state (theoretical construction of the model); -the underground shade (a rock "milieu" description); -the rock fluid (representations of the rock creation and ritual); -the public mystery (representations of the destination of the rock message and audience). The annexe part (second volume) contrains 405 pages

Abstract:
Erosional processes of solid materials have been the focus of many researchers around the world. Erosion can commence within a wide range of material strengths depending on the amount of water-driven energy and material properties. Erosion could also occur due to Aeolian effects as well as chemical weathering but these forcings are not of the focus of this research. Instead, the focus here is on rock erosion in waterways and in particular downstream of dams. Rock erosion mostly takes place at the downstream of dams where the water conveys through the spillbays from upstream to the downstream during an extreme event. This phenomenon threatens both the structural soundness of the dam with implications to the public safety. It usually occurs when the applied hydrodynamic forces (average and fluctuating) exceed the strength of the rock mass formation. Rock scour at the downstream of dams due to high velocity impinging jet is a complex and highly dynamic process. So a deeper understanding of the process is crucial to determine the rock scour rate and extent. Hydraulic laboratory models have been employed to investigate hydraulic processes and proved to be reliable tools for testing soil/sediment erosion; however, the study of rock scour remains challenging. The prototype rock formation cannot be utilized in the laboratory models because the flowing water in the scaled model contains much less energy and exerts less forcing. On the other hand, the use of granular sediment (non-cohesive), as a standalone approach to mimic the rock formation is not a precise method, since it will most probably lead to inaccurate results. The idea of using a mixture of granular and cohesive sediment is investigated here to adequately simulate the rock erosion process in the laboratory scaled models. The granular sediment represents the rock blocks while the cohesive additive is a binder to keep the granular sediment together. The rock scour process can occur through four mechanisms; fracture failure, block removal, fatigue failure and abrasion. In this study, because the focus is on the hydrodynamic forcing effects on rock erosion, we assume that in the completely and intermittently jointed rock, erosion is mostly governed by fracture, block removal and fatigue failure. Abrasion is triggered by collisional effects and is not the focus here. So, we hypothesize that if the rock formation considered being pre-fractured, it can be simulated using a mixture of non-cohesive sediment with cohesive additive. This method was utilized to assess the rock scour process at the downstream of the Priest Rapids Dam. The Priest Rapids Dam project was part of a series of projects that was conducted at IIHR-Hydroscience & Engineering at The University of Iowa and sponsored by the Public Utility District No. 2 of Grant County, Ephrata, Washington (GCPUD) to investigate juvenile salmonid migration at the Wanapum/Priest Rapids Development. It is a hydroelectric, concrete gravity, and mid-elevation dam owned and operated by Public Utility District No. 2 of Grant County, Washington (the "District"). To aid the District in their evaluation of fish passage, IIHR-Hydroscience & Engineering constructed comprehensive three-dimensional physical models of the forebay and tailrace of Priest Rapids Dam and a third model of spillbays 19-22 and powerhouse Unit 1 (sectional model). As part of the last phase of the project, it was crucial to assess the effects of the newly designed fish bypass system on the downstream rock foundation scour. To investigate this process, the 1:64 Froude-based scale tailrace model of the dam was utilized. The mixture of gravel, bentonite clay, and water was employed to mimic the rock formation and simulate the bedrock scour process in the model. Series of preliminary experiments were conducted to find the optimum mixture of gravel, bentonite and water to accurately replicate an existing scour hole observed in the prototype tailrace. Two scenarios were considered. First, tests were conducted to estimate the scour potential downstream of the fish bypass, which is currently under construction. Second, the scour potential downstream of the dam was also assessed for the Probable Maximum Flood (PMF) with the fish bypass system running. Based on the model tests results and observations, the simulated bedrock (mixture of gravel and cohesive bentonite) was able to replicate the rock scour mechanisms, i.e. fracture process, block removal and fatigue observed in nature. During the fish bypass scour tests, it was observed that the erosion process occurs in the form of block removal and fatigue failure. During the PMF scour test, instead, it was observed that the mixture is eroded in chunks of substrate. This process can be representative of fracture failure in rock which occurs when the induced pressure fluctuation exceeds the fracture strength or equivalently toughness of the rock. In the preliminary phase of this work it was recognized that a prerequisite for replicating the processes in the laboratory is the proper preparation of the mixture. There is limited information available in the literature about how much cohesive additive is required to simulate the erosional strength of the prototype rock formation. For this reason, in this study the effort has been made to develop a method to simulate the rock formation for studying rock scour process in the laboratory analog scaled models. To simulate the bedrock formation, various combination of granular sediment (gravel), cohesive additive, and water were created and tested. Choosing an appropriate cohesive additive concentration is critical and nearly a balancing act. An appropriate cohesive additive concentration should be cohesive enough to bind the material and not too strong to be eroded by the flowing water in the scaled models. Moreover, its properties should not change over time. Various cohesive additives can be mentioned i.e. kaolin clay, bentonite clay, cement, grease, paraffin wax. Among all of them, bentonite clay was chosen as the appropriate cohesive additive due to its swelling characteristic. When bentonite is mixed with granular sediment, it is restricted by the non-cohesive sediment grains. The bentonite expands to fill the voids and forms a tough, leathery mineral mastic through which water cannot readily move. In order to assess the erodibility of the mixture the Jet Erosion Test (JET) apparatus was used. The JET apparatus is a vertical, submerged, circular, turbulent impinging jet which is widely accepted and utilized to assess cohesive soil erosion through flow impingement. There are devices such as flumes which could be effectively used for bank erosion where the flow shear action is prevalent. In this study, it was sought important that the forcing replicated in the experiments was of the same nature (normal impinging forcing instead of shear forcing) as observed in the downstream end of a dam. For this reason, JET was chosen as it provided a larger range of stresses (ranging between 100-1000 Pa) comparing to the flume device. The apparatus was designed based on the device developed by Hanson and Hunt (2007) and built at the IIHR-Hydroscience & Engineering. Various replicate samples were made with different combinations of gravel, sodium bentonite clay, and water. To determine the erosional strength of the samples (critical stress) they were tested using the JET apparatus. The critical stress was determined as the stress associated with zero eroded mass. The results revealed that the erosional strength of the simulated bedrock mixtures highly depends on the amount of adhesive component (bentonite clay). The mixtures with the higher percentage of bentonite clay are less susceptible to erosion. The erosion threshold plot - similar to Annandale's plot - for the simulated bedrock mixtures was developed. Using the erosional strength of the simulated bedrock mixtures, a step-by-step systematic method was developed to determine the optimum combination of weakly cohesive substrate in order to simulate the strength of the prototype bedrock. The method is based on the Annandale's erodibility index method and requires information about the prototype bedrock strength (erodibility index). The method is explained in conjunction with the Priest Rapids Dam project example. The old trial and error method to establish an optimum weakly cohesive substrate is costly and time consuming especially in the case of large scale laboratory models. Also, the applicability of the method would be questionable when there is not enough information or a past data set that can be used as a baseline (witness) test. The new method eliminates these problems and the optimum mixture can be established using the geological information of the prototype bedrock formation.

Abstract:

In this thesis, fractured rock masses are treated asequivalent continua for large-scale analyses of rockengineering projects. Systematic developments are made for thedetermination of equivalent mechanical and hydraulic propertiesof fractured rock masses using a hybrid discrete fracturenetwork - distinct element method (DFN-DEM) approach. Thedetermined equivalent properties are then used for a far-fieldfinite element analysis of the thermo-mechanical impacts on thestress, deformation and permeability of fractured rockssurrounding a hypothetical geological repository of nuclearwaste. The geological data were extracted from the results ofan extensive site investigation programme at Sellafield, UK,conducted by Nirex UK Ltd.

The scale dependencies of the hydraulic and mechanicalproperties were investigated by using multiple realizations ofthe fracture system geometry with increasing model sizes untilproperly defined hydraulic and mechanical representativeelementary volumes (REVs) were reached. The validity of thesecond order permeability tensor and the fourth-ordermechanical compliance tensor were tested for continuum analysesat larger scales. The REV was determined to be around 5 m formechanical and hydraulic data in this study.

Analysis of the stress-dependent mechanical and hydraulicproperties shows that the effect of rock stresses is crucial.The elastic moduli increase significantly with the increase ofstress and an empirical equation of stress-dependent elasticmodulus is suggested based on results of numerical experiments.Calculations of the Poisson's ratios suggest greater valuesthan are normally assumed in practice. Depending on the stateof stress, permeability decreases or increases with increasingcompressive stress. Stress-induced flow channeling effect iscaptured by numerical modeling for the first time and detailedmechanisms of shear dilation of fractures are provided. Basedon the numerical experiments, a set of empirical equations wassuggested for the stress-dependent permeability, consideringboth normal deformation and shear dilation of fractures.

Thermo-mechanical impact on the performance of ahypothetical repository at a far-field scale (5 km by 1 km) wasinvestigated with the stress-dependent equivalent propertiesdetermined at the REV scale. This analysis shows thatmechanical responses vary significantly depending on how themechanical properties were determined. The change ofpermeability due to the thermal loading is, however, notsignificant in this particular case.

The thesis provides a framework for systematic analysis oflarge-scale engineering applications in fractured rock masses,such as geological repositories of nuclear wastes.

Abstract:
Un massif rocheux fracturé, dont le comportement géo-hydromécanique a été étudié depuis plusieurs années, a été instrumenté sismiquement. L'intérêt du site réside dans le fait qu'on peut induire artificiellement une charge hydraulique connue et mesurer des déplacements, des pressions hydrauliques sur plusieurs points significatifs. Les résultats des essais in-situ mettent en évidence l'existence d'une micro-sismicité induite par une variation de pression avec une grande repétitivité. A partir des résultats des essais in-situ, a été formulée l'hypothèse que l'activité micro-sismique est associée à l'augmentation de la pression d'eau dans les zones moins perméables du massif rocheux. Une modélisation numérique du site avec la méthode des Eléments Finis a été réalisée pour determiner l'amplitude des variations de contraintes induites par la mise en charge hydraulique et vérifier si elles pouvaient engendrer des sources sismiques. Des échantillons prélevés ont permis de déterminer, en laboratoire, le comportement mécanique de la roche intacte et des joints rocheux et la sismicité associée. Il s'avère que les variations de contrainte calculées pour le site ne sont pas suffisantes pour générer la sismicité observée au laboratoire. Une modélisation micromécanique à l'échelle du joint rocheux avec la méthode des Eléments de Contour (Discontinuités de Déplacement) a été réalisée pour simuler le comportement hydro-mécanique tenant compte de la morphologie du joint. Les résultats numériques sont en accord avec les obsenTations de laboratoire et montrent que la mise en charge hydraulique d'un joint rugueux peut engendrer des instabilités lors de l'ouverture des aires de contact compatibles avec la micro-sismicité observée sur le site
This dissertation forms part of a larger research field which deals with using seismic monitoring systems to better understand the behavior of natural rock slope appealing to the laboratory and in-situ experiments and the numerical simulation. For this purpose, a small scale rock mass, former instrumented from the geo-hydro-mechanical point of view, bas been chosen for installing a seismic monitoring system. Ln this site, it is possible to easily induce a known hydraulic charging and to measure displacements and pressures in many meaningful points. The results of the in-situ experiments highlight the existence of micro-seismicity induced by a variation of water pressures and the repetitiveness either of the hydro-mechanical and micro-seismic behavior. From results, it bas been hypothesized that the micro-seismic activity onsets when water pressure increases in less permeable zones. The Finite Elements numerical modeling of the site allows to calculate the stress variations due to hydraulic charging and to assess if stress variations could generate seismic sources. Series of cores have been taken from the site in order to tested rock material and rock fractures in laboratory, associated with acoustic emissions. Lt results that little stress variations due to water pressure, calculated for the site, do not explain the micro-seismicity observed in laboratory. A micro-mechanical model using Boundary Elements Method (Displacements Discontinuity Method) which simulates the hydro-mechanical behaviour of rock joints sample under normal compression is proposed taking into account the joint topography. Results confirm the laboratory observations and show that the hydrostatic charging can induce instabilities, when contact areas open, comparable to the ill-situ micro-seismicity

Abstract:
La presente investigación propone la caracterización de la escena de rock en la ciudad del Cusco en función a una imagen históricamente construida de la ciudad alrededor de las nociones de lo inca, lo andino y el turismo. Asimismo, analiza y reflexiona sobre los procesos de reinterpretación de estas nociones - consideradas como referentes locales - en su producción musical. Los lineamientos teóricos que orientan esta investigación están constituidos por estudios sobre el concepto de escena musical y la idea del rock como fenómeno global y medio de reinterpretación de manifestaciones culturales e identidades locales. Junto con estos trabajos, se exponen estudios que sustentan la construcción de la identidad “cusqueña” de la ciudad basada en las tres nociones previamente mencionadas y asimismo se revisan postulados que proporcionen una reconstrucción socio musical de lo andino. Desde inicios del siglo XX, diversas iniciativas por parte de intelectuales, artistas, el estado y la población local en general han venido consolidando una identidad del Cusco caracterizada por un imaginario con base en lo incaico, lo andino y lo turístico. Este imaginario se ha consolidado a lo largo del tiempo como principal factor articulador de las manifestaciones de la ciudad. En ese sentido, una expresión como el rock, inserta dentro de un contexto con dicha particularidad, es también determinada por este imaginario. Desde esta perspectiva, la hipótesis que sustenta la presente investigación sostiene que la caracterización de la escena de rock en el Cusco está influenciada por los elementos asociados a la imagen históricamente construida de la ciudad. El cuerpo de información que permite verificar esta hipótesis tiene como fuentes primarias testimonios de agentes del medio local tales como músicos, públicos, productores, gestores culturales y empresarios y como fuentes secundarias material audiovisual relacionado a la producción musical local que comprende discos, canciones, videos, imágenes y publicaciones en internet.

Full text
Abstract:
Au début des années 80, les musiques rock en région en France sont dominées par un fort discours anti-institutionnel qui amène ses acteurs à développer un système d'organisation de la vie musicale en marge des institutions culturelles traditionnelles. Une décennie plus tard, commence à s'imposer un discours de professionnalisation qui prend appui sur de véritables institutions musicales dont l'émergence n'est pas allée sans un soutien accru des pouvoirs publics. Fondée sur une enquête menée en région Franche-Comté, cette étude a cherché à comprendre les ressorts de cette évolution des musiques caractérisées par l'amplification. La problématique s'inscrit dans la théorie des rapports de domination symbolique et s'appuie sur le concept de "champ" de Pierre Bourdieu. Elle privilégie une analyse des transformations constatées en terme de processus de légitimation culturelle et, inséparablement, d'institutionnalisation des pratiques musicales. Comprendre le sens des évolutions des musiques amplifiées revenait alors à analyser les luttes sociales qui structurent les "champs territoriaux des musiques amplifiées", et la place qu'y occupent les pouvoirs publics. L'hypothèse consistant à dire que ces derniers ne déterminent pas le principe de ces luttes, mais leur issue. Pour mener à bien cette étude, nous avons dû construire un modèle d'analyse qui permette de restituer la totalité du processus : l'avant et l'après institutionnalisation. Nous avons dû associer au concept de " champ " de Pierre Bourdieu, le concept de "monde" d'Howard S. Becker. L'investigation a alors privilégié la lecture des archives et l'observation participante et in vivo afin de restituer les transformations structurelles et comportementales par la description ethnographique. Le sens pris par ces transformations était recueilli par entretien auprès des responsables des institutions musicales retenues pour l'enquête. Il devenait ainsi possible de mettre en évidence les mécanismes qui accompagnent l'apparition d'un champ formé sur le modèle des champs de culture savante et d'observer les changements que l'institutionnalisation des musiques amplifiées introduit dans les formes de sociabilité et de socialisation, dans la nature même de la culture musicale, et, par-là, dans le sens que ces musiques prennent pour ceux qui les vivent
In the early 1980s, regional rock music in France was dominated by an anti-institutional discourse that lead those involved to develop a lifestyle on the margin of traditional cultural institutions. A decade later, professionalism becomes an increasingly integral component of rock music with the growing importance of veritable musical institutions, institutions whose emergence came in part out of growing support of public authorities. Founded on surveys conducted in the Franche-Comté region, a study has attempted to understand better the forces behind this evolution in music characterized by electric amplification. The problem lies within the theory of symbolic domination in relationships and is demonstrated through Pierre Bourdieu's "field" theory. The theory uses an analysis of the changes that is described in terms of a processes of cultural legitimization, and, inseparably, an institutionalization of musical practices. The understanding of the direction of the evolution of amplified music is thus rooted in the social struggles that shape the "territorial field of amplified music", and in the area occupied there by authorities. The comprised hypothesis explains the authorities as not being determinant in the issue of the struggles, but in their outcome. To see our study through to a successful end, we were obliged to construct an analytical model that reconstitutes the totality of the process : before and after the institutionalization. We had to link to Pierre Bourdieu's "field" concept, Howard S. Becker's concept of the "world". Thus the study gives importance to the reading of archives and participant observation and in vivo in order to reconstruct and the structural and behavioral transformations using ethnographic description. The significance of the transformations was gathered from interviews with heads of the musical institutions taken for the study. In this way is became possible to clearly show the mechanisms that accompanied the appearance of a sphere established on the model of sophisticated cultural spheres, and to observe the changes that the institutionalization of amplified music introduced, in the form of sociability and socialization, in the nature itself of musical culture, and, in the same manner, in the meaning that the music embodies for those that live it

Abstract:
La sismique et la sismologie sont des moyens puissants pour comprendre la croûte terrestre.Ces deux méthodes reposent notamment sur une compréhension approfondie de la propagation des ondes sismiques dans des milieux sédimentaires saturés en fluides.Ce travail a pour but de comprendre les effets statique et dynamique du fluide sur la réponse élastique de roches clastiques saturées.Deux points spécifiques de l'interaction fluide-roche sont étudiées: (i) l'intéraction physico-chimique, le « shear weakening », affectant la réponse élastique de la roche; et (ii) l'interaction mécanique, le « frequency effect », induisant une dépendance des propriétés élastiques à la fréquence de mesure.Deux types de roches sont étudiés: les grès et les calcaires.Ces échantillons de roche sont sélectionnés pour leurs propriétés isotropes et leur forte concentration en un minéral dominant: le quartz pour les grès et la calcite pour les carbonates.Le phénomène de « shear weakening » est d’abord étudié pour de très faibles saturations en eau afin de tester l’effet de l'adsorption.Aucun affaiblissement n’est mesuré dans les carbonates, au contraire un affaiblissement élastique global est observé dans certains grès : Les modules de cisaillement et d’incompressibilité sont également affectés.L'effet ne semble pas provenir d'une différence intrinsèque entre les minéraux de quartz et de calcite, mais d’une différence microstructurale entre roches. Un modèle micromécanique est développé, montrant que les deux paramètres clef sont le caractère granulaire et le degré de cimentation de la roche.Le même résultat est obtenu pour les compressibilités mesurées lors des saturations totales en eau.Ces deux études montrent que l'adsorption est la cause du « shear weakening », et implique un affaiblissement élastique global dans les roches granulaires peu cimentées (gréseuses et probablement carbonatées).L'effet de fréquence est étudié dans des grès de Fontainebleau et de Berea. Deux méthodes sont étudiées, toutes deux basées sur le principe de "stress-strain" (i.e. contrainte-déformation): l'oscillation "isotrope" (de la pression de confinement) et "déviatorique" (de la contrainte déviatorique).Ces deux modes d'oscillations sont tout d’abord calibrés à l’aide de plusieurs standards (e.g. aluminium, verre, gypse, plexiglass).Les échantillons de roche, saturés par des fluides de différentes viscosités, sont ensuite mesurés avec ces deux modes d'oscillation.Pour le premier mode d'oscillation, dit "isotrope", ce travail a permis de (i) mettre en évidence trois régimes élastiques distincts;et (ii) mesurer à la fois la conséquence (i.e. dispersion et atténuation du module d'incompressibilité) et la cause (i.e. écoulement fluide global) de la transition en fréquence entre état drainé et état non-drainé.Pour le second mode d'oscillation, dit "déviatorique", le module de Young et le coefficient de Poisson sont mesurés sur une gamme de fréquence apparente de [10-3;105] Hz.Pour un échantillon de grès de Fontainebleau, les deux transitions élastiques sont observées. Les mesures sont cohérentes avec les théories existantes.Un modèle 1D, prenant en compte les conditions de bord du système, est finalement développé. Ce modèle donne des résultats cohérents, et explique l'effet du volume mort sur les propriétés mesurées dans le cas d'une oscillation « isotrope »
Seismics or Seismology are powerful tools to investigate Earth's crust. However, both rely on seismic waves that travelled through fluid-saturated sedimentary layers. This work, mainly experimental, aims at understanding the static and dynamic effects of the saturating fluid on the elastic response of clastic rocks.In this framework, two specific studies are emphasized:(i) the rock-fluid physico-chemical interaction, often addressed as the "shear weakening" effect, thought to affect the rock overall elastic response; and (ii) the rock-fluid mechanical interaction, addressed as "frequency effect", thought to induce a dependence of elastic properties to the measuring frequency.Two main rock types are investigated: Sandstone and Limestone. All rock samples are chosen to be isotropic and composed of a dominant mineral content, i.e. quartz for sandstone and calcite for limestone

Nous expliquons finalement par la musiquecomment la sauvagerie a pu devenir une réalité tangible du rock’n’roll en tant que dynamiquede création, comme l’expression musicale d’un « excès mesuré ». Nous confrontons cesreprésentations de la sauvagerie à la musique de Jerry Lee Lewis, de Little Richard et de LinkWray. Ce travail musicologique éclaire les innovations de leur style personnel, dans la réalitéobjective de leurs singularités musicales, pour mieux rendre à la « chose sauvage » toute sonimportance dans la dynamique de création du genre musical
This dissertation analizes the myth of the wild side such as it has been represented in theAmerican fifties through rock ’n’ roll. Teen rebellion is seen as a social fact which stirred up anew representation of the modern wild side, through ideals confronted to the adult world andits own ideals. Then we try to find the reasons why rock ’n’ roll, and more specifically ElvisPresley’s music, appeared as a musical genre which embodied and purveyed that wild side.Analysing two different versions of Hound Dog – the typically African American version of« Big Mama » Thornton and Elvis Presley’s rock ’n’ roll creation – allows us to underline theinnovations brought by rock ’n’ roll and the representations of wilderness : the birth of ElvisPresley’s style, which we can reason through the idea of cross-pollination, then thecrystallisation of a typically wild style that reveals various innovations through thecondensation of various musical elements coming from the most rejected musics in the UnitedStates. Then we explain through music itself how the wild side became a tangible reality inrock ’n’ roll, a creative dynamic and the expression of a « moderate excess ». Finally, weconfront those representations of the wild thing to the music played by Jerry Lee Lewis, LittleRichard and Link Wray. Musicology sheds light on the innovations contained in their ownpersonal styles and the reality of their musical particularities thus allowing us to show thewild side as a crucial thing in the creation of rock ’n’ roll

Recopilar una importante cantidad de información para recrear en el texto el ambiente social, económico, circunstancial y artístico en el cual se gestó un movimiento de rock criollo a partir de 1966. Entregar información sobre los centros neurálgicos de la escena, el tipo de público, el carácter de estos músicos y la reacción de su entorno. Descubrir la real dimensión de su alcance como movimiento generacional en su tiempo y revisar la discografía de la época para explicar a quienes no tienen acceso a estos discos de qué se trataban. Debido a que esta memoria de título pretende tener un carácter testimonial para reafirmar los acontecimientos y, además, obtener una narración más ágil para el lector.

Abstract:
Die Dissertation befasst sich mit der Optimierung des Schneidprozesses bei der Gesteinsgewinnung und der Erarbeitung eines Modells zur Prognose der relevanten Arbeitsgrößen unter Berücksichtigung der Abnutzung der Schneidwerkzeuge. Die Untersuchungen wurden mit Rundschaftmeißeln unterschiedlicher Verschleißzustände durchgeführt. Gegenstand der Untersuchungen waren die von den Schneidparametern abhängigen Größen wie Schneidkräfte, spezifische Energie, Staubmengenanteil und Stückigkeit des gewonnenen Gesteins. Es wurden die Auswirkungen des Meißelverschleißes auf die optimalen Schneidparameter festgestellt, denen beim Einsatz einer Gewinnungsmaschine oder bereits in der Konstruktionsphase des Gewinnungsorgans Rechnung getragen werden sollten.

Abstract:
Pour évaluer la température d’enfouissement subie par les roches sédimentaires, une large gamme de géothermomètres est disponible, basés sur les constituants organiques ou minéralogiques de ces roches. Comme pour toutes les techniques expérimentales, elles présentent des avantages et des inconvénients. Dans cette thèse, nous utilisons une approche magnétique pour estimer la température d’enfouissement. Dans une première partie, nous avons étudié l’assemblage magnétique de puits sélectionnés à travers le monde pour mieux caractériser le géothermomètre magnétique MagEval. Deux calibrations ont pu être établies. Pour décrire la relation entre la température maximale d’enfouissement subie par les roches et leur assemblage magnétique, nous avons réalisé des expériences de chauffe en laboratoire de 50 à 130°C sur des argilites non métamorphosées. Les chauffes expérimentales ont montré que des nanominéraux magnétiques sont continuellement produits avec la température. Dans une deuxième partie, nous avons étudié les propriétés magnétiques des roches sédimentaires dans deux sites géologiques analogues pétroliers : le bassin des Grès d’Annot dans le SE de la France (température d’enfouissement 60-250°C) et les chaînes plissées de la Valley & Ridge Province dans les Appalaches, Etats-Unis (température d’enfouissement _120-200°C). Ces études suggèrent une évolution des principaux minéraux magnétiques avec la température. Magnétite, nanogoethite et pyrrhotite sont principalement formées. Les différents résultats obtenus dans cette thèse nous ont permis de proposer une évolution des minéraux magnétiques en fonction de la maturité des roches et de la température
To evaluate the burial temperature experienced by sedimentary rocks, a wide range of geothermometers is available, based on both organic and inorganic constituents of these rocks. Like all experimental techniques, they show limitations. In this thesis, we used a magnetic approach to estimate burial temperature. In a first part, we studied the magnetic assemblage of selected boreholes over the world to better characterize the magnetic geothermometer MagEval. Two calibrations were established. To assess the relationship between the peak burial temperature experienced by the rocks and their constitutive magnetic minerals, we conducted laboratory heating experiments from 50 to 130°C on unmetamorphosed claystones. The experimental heating showed that nano magnetic minerals are continuously produced with temperature. In a second part, we investigated rockmagnetic properties of sedimentary rocks from two geological plays of petroleum interest : the Grès d’Annot basin in SE France (burial temperature 60-250°C) and the fold-and-thrust belts of the Valley & Ridge Province in the Appalachians, USA (burial temperature _120-200°C). These studies suggested an evolution of the main magnetic minerals with temperature. Magnetite, nanogoethite and pyrrhotite are mainly formed. All the conducted analyses lead us to propose an evolution of the magnetic minerals as a function of the maturity of the rocks and temperature

Abstract:

Svensk musikindustri har under de senaste årtiondena åtnjutit stora framgångar på den internationella marknaden. Export Music Sweden grundades för att stötta och marknadsföra svensk populärmusik utomlands. VD Christer Lundblad sade 2003 att intäkter från konserter ökar kraftigt. Anledningar till detta kan vara att den ökande illegala nedladdningen av musik ger ett ökat ekonomiskt utrymme för konserter, samt att människor idag värderar upplevelser högre än tidigare. Eftersom mer pengar spenderas på konserter blir prissättningen mer betydelsefull. Ur ett rent ekonomiskt perspektiv borde konsertbiljetter prissättas för att maximera vinsten. Ett sätt att göra detta är att prisdiskriminera. Vi har funnit att detta inte görs i så stor utsträckning inom kon-sertindustrin, vilket har lett oss till att ta reda på varför så inte är fallet.

För att ta reda på varför inte prisdiskriminering sker i större utsträckning har vi intervjuat sju personer inom de grupper, i konsertindustrin, som påverkar prissättningen. Dessa grupper är artister, management, turnéproduktionsbolag och skivbolag. Vi har även studerat litteratur rörande prisdiskriminering och konsertindustrin, i form av ve-tenskapliga artiklar, böcker och rapporter.

Uppsatsen diskuterar hur prisdiskriminering av konserter går till, vilka som är inblandade i prissättningsbeslutet, samt deras syn på prisdiskriminering. Den tar även upp andra faktorer som påverkar prissättningen av konserter.

I uppsatsen kommer vi fram till att det finns två anledningar till att konserter inte prisdiskrimineras i större utsträckning. En anledning är praktisk och innebär att konsertplatsens attribut inte tillåter platsindelning och således prisdiskriminering. Den andra anledningen bygger på konsertarrangörers lättja samt artisters invändningar mot pris-diskriminering. Vi redogör även, utifrån undersökningens resultat, för att utvecklingen pekar på att konserter kommer att prisdiskrimineras i större utsträckning i framtiden.


Swedish music industry has, during the latest decades, been highly successful interna-tionally. Export Music Sweden, ExMS was founded to support and market Swedish music abroad. ExMS Managing Director Christer Lundblad said in 2003 that the income made from concerts is growing rapidly. The reason for that development might be that the illegal downloading of music leave people more money left to spend on concerts. Furthermore, the development might spawn from the fact that people value experiences higher than before. Moreover, when more money is spent on concerts the pricing becomes more important than ever. Concert tickets should, if seen in an economical perspective, be priced to maximize revenue. One way of doing that is to price discriminate. We have, through a pre-study on the subject, established that concerts are not price discriminated as extensively as they could. That fact has made us curious as to why that is.

In order to find out why concerts are not price discriminated more extensively we have interviewed seven people belonging to groups involved in the pricing process of concerts. These groups are artists, managers, concert arrangement agencies and record labels. Furthermore, we have studied literature on price discrimination and the concert industry.

The thesis discusses the pricing of concerts; which people who is involved in the decisions concerning the pricing of concerts and their views on the subject. In addition, the thesis also contains other factors influencing the pricing of concerts.

In conclusion, we find that there are two reasons explaining why concerts are not price discriminated more extensively. One is practical and involves the fact that some concert venue attributes does not allow price discrimination, since the crowd cannot be divided into different sections. The other reason is the fact that concert arrangement agencies are to comfortable to price discriminate, and that artists are unwilling to price discriminate for different reasons. Furthermore, the thesis’s results indicate that concerts will be price discriminated more extensively in the future.

Abstract:
El gótico es un estilo de arte medieval arraigado en la cultura mundial, es una de las corrientes artísticas que han muerto y renacido con nuevas manifestaciones, como la literatura, el cine o la música, a lo largo de la historia. El gótico ha creado diversas maneras de ver la vida, desde la plástica hasta la filosofía, que siguen permeando de manera contundente a nuestra cultura. Es por eso que el trabajo que aquí se presenta es un análisis estructural que explica el porqué de una literatura gótica mexicana. Al respecto, debo decir que se podían tomar textos narrativos de esta índole, porque no tienen las características para poder denominarlos de esa manera.

Abstract:
El presente trabajo titulado Análisis sociolingüístico de las canciones del grupo de rock Trémolo, es un acercamiento al lenguaje de un sector de la juventud que hace música rock heavy metal en la ciudad de Lima. Esta investigación está inmersa dentro de la amplia gama de posibilidades y temas de estudio que ofrece el campo denominado “uso del lenguaje”. Específicamente, se analiza los textos de las composiciones del género musical rock (Rock and roll): género de ritmo muy marcado, derivado de una mezcla de diversos estilos del folclore estadounidense, y popularizado desde la década de 1950. Del uso de la forma simple rock se derivó el término roquero, que denomina a la persona que practica o es muy amante de este género musical’. Los textos estudiados en el presente trabajo fueron seleccionados del repertorio de composiciones musicales de una banda nacional: Trémolo que tiene características propias y definitorias. El análisis de los textos se centró básicamente en aspectos estructurales y semánticos, así como algunos detalles lingüísticos particulares como los sentidos contextuales que las formas lingüísticas expresan en las composiciones musicales de los ritmos denominados rock. Además de las estructuras lingüísticas, en el análisis se ha detallado los usos léxicos sui géneris que utiliza este grupo para expresar los mensajes contenidos en sus composiciones. El análisis de los textos de la banda ‘Trémolo’ ha permitido determinar algunas tendencias generales presentes en la selección de la temática, claramente determinada por factores de índole sociocultural de los componentes del grupo.

Abstract:
I denna kandidatuppsats undersöker jag företeelser i svenska moderna (2000-talet och framåt) pop/rock- låttexter. Jag försöker ta reda på vad som kännetecknar de bästa texterna kontra ”mindre bra” sådana. Detta gör jag genom korpusanalys med avseende på allmän statistik, läsbarhet, ordklass- och ordfrekvenser. Jag tittar särskilt på de tolv svenska pop/rockalbum som vunnit Grammis för ’Årets textförfattare’ samt artisten Håkan Hellströms hela låtkatalog eftersom han vunnit priset flest gånger. Som referenser har jag tolv framgångsrika album av artister som aldrig vunnit nämnt pris, samt artisten Per Gessles (som är oerhört framgångsrik utan att ha vunnit priset) hela låtkatalog under nämnd tid. Jag förväntade mig att finna lingvistiska aspekter som skiljer vinnande - och Hellströms texter från referenskorpusarna. Optimalt hade varit att finna en slags formel för bra/ vinnande text. Vad jag fann var att det finns lingvistiska element som är fördelaktiga vid författande av låttexter, aspekter som ofta, men inte alltid, är gemensamma för bra/vinnande texter. Däremot fann jag ingen optimal formel för hur en text bör skrivas.
