Texto completoA multi-layer analysis of the digital image is then formulated where fragments on the surface are grouped into three layers, each of which is categorized by global characteristics and is related to other neighbouring layers by local characteristics. These local relationships between the layers are used to approximate the missing parts of the fragment contour.
An extensive analysis of the sieving process is used in building the relationship between the shape and the size of individual fragments. Using this relation, a new multivariable measure for each fragment is developed. These measures are used in estimating the size distribution of the muck-pile and compared with other existing measurement techniques. This comparison proves the robustness of the technique developed in this thesis.

Texto completoModern hydraulic fracturing designs assume that drilled formations are both isotropic and homogeneous, and fractures are linear and symmetrical. However, unconventional resources are often obtained from formations that are both anisotropic and heterogeneous, resulting in complex fracture behavior. The objective of this study is to evaluate fracture behavior based on the influence of anisotropy and water saturation. Isotropic and homogeneous Austin Chalk, Berea Sister Gray Sandstone, and Silurian Dolomite, laminated anisotropic and heterogeneous Parker Sandstone, Nugget Sandstone, and Winterset Limestone Carbonate, and fully anisotropic and heterogeneous Edwards Brown Carbonate cores were ordered for testing. Brazilian discs were cut according the ISRM and ASTM standards, and prepared as dry, brine saturated, and fresh water saturated samples. All samples were fractured by the Brazilian test, and laminated anisotropic samples were tested at various loading angles (0?, 15?, 30?, 45?, 90?). Tensile strengths were calculated using the peak load of the primary fracture of each sample, and the fractures were observed for geometrical trends. Additionally, the strain development of each fracture was analyzed through the application of Digital Image Correlation (DIC) software. The results determined that anisotropy and saturation can decrease the tensile strength of a formation. The fracture geometries were influenced by planes of anisotropic lamination, and fully anisotropic rocks produced winding, erratic fractures. DIC allowed for closer 101 examination of fracture development, and identified that saturation can cause failure along lamination planes subjected to less than the maximum, load induced stress. This research can be utilized to improve the hydraulic fracturing design models to optimize formation fractures, and increase revenue for the oil and gas industry.

Texto completoVid projekt inom berganläggningar och gruvor är det viktigt att känna till de rådande spänningar i berget i ett säkerhets- och konstruktionsperspektiv. I Sverige används framförallt två undersökningsmetoder - överborrning eller hydraulisk spräckning. Två metoder som dock är dyra och relativt få mätserier kan genomföras. En alternativ metod har därför undersökts där borrhålsväggen lokalt avlastas genom sågade slitsar. Töjningsmätning sker genom att fotografera borrhålsväggen innan och efter sågning av slitsarna. Därefter sker bildbehandling via Digital Image Correlation (DIC). En metod som jämför en pixels placerings förändring genom att matcha pixeln via gråskalan. Examensarbetet kan man säga är grovt indelat i tre delar. Den första delen innefattar teorin som handlar om bergspänningar samt nuvarande mätmetoder för att mäta bergsspänningar. Andra delen är en litteraturstudie som behandlar den bakomliggande teorin för optik och bildbehandling med DIC samt en kort undersökning om det är möjligt att använda den optiska tekniken som finns i en smartphone. Sista delen utgörs av numeriska modelleringar i 2D för att verifiera om det går att fullständigt avlasta ett borrhål genom sågade slitsar. Med optik som finns i en smartphone kan bergväggen vara i fokus på bara ett par millimeters avstånd. DIC i sig är en teknik som är så pass utvecklad att precisionen i mätningarna är väldigt god. Förutsatt att bildbehandling görs korrekt och bildkvalitén är god. Kombinationen med optik liknande den från smartphone och bildbehandling med DIC är dock inte fullständigt undersökt. Enbart en jämförbar studie har hittats där deformationsmätningar har gjort med hjälp av en Surfplatta från Sony. Denna undersökning visade att mätfelet mot en referenskamera är cirka 1%. Dock förstärks mätfelet vid töjningsmätningar. Förstärkningen beror dock även av deformationsskillnaden mellan innan och efter avlastning. Den numeriska delen har visat att det går att lokalt avlasta bergväggen fullständigt för det undersökta spänningsförhållandet. Dock krävs det att två slitsar sitter på ett litet c-c avstånd samt är relativt djupa. Två undersökta slitsuppsättningar har visat på fullständigt avlastning, samt ytterligare ett fall som skulle kunna vara användbart.

Texto completoThe physical properties of the coarse fraction of the till (0.4 to 20 cm) and the surface boulders have been studied at two different sites in Sweden. The research work included: development of a new image analysis software for 3D size and shape measurements of particles; lithological analysis on multiple size fractions in till and magnetic susceptibility survey on coarse till clasts, surface boulders and local bedrock.
The new 3D image analysis method provides an enormous amount of size and shape data for each particle in the coarse fraction (2 to 20 cm) in till. The method is suitable for field study, cost effective and the software is executable in Matlab. The field imaging method together with the image analysis software give non subjective results of size and shape of coarse particles and makes it feasible and easy to study representative sample size, which is one tonne for testing clasts of size up to 20 cm.
The lithological analysis of the multiple size fraction of the till clasts has been investigated on six different size fractions of the till (0.4 to 20 cm); the result of the different samples from the two sites shows that this method can potentially be used as a stratigraphic tool in the areas where there is no unique indicator lithologies.
The magnetic susceptibility has been made on the surface boulders, the 6-20 cm till fraction and on insitu bedrock outcrops near to the study sites. The method has good potential for determining stratigraphic relationships between different till units as well as for determining the provenance ofcoarse clasts and surface boulders.

Texto completoThis project aims at an optimization of geostructural modeling methodolgies, leading to a better knowledge and a better management of the rock risk impacting the railway system. Acquired 3D models are exploited in order ton convert 3D point clouds into geostructural analysis. Hence, we have developed a semi-automatic process that allows 3D models to be combined with the results of field surveys in order to provide more precise analyses of rock faces, for example, by classifying rock discontinuities into subsets according to their orientation. A second approach is proposed, combining both 3D point clouds (from LiDAR or image matching) and 2D digital images. Combining these high-quality data with the proposed automatic and manual processing method greatly improves the geometrical analysis of rock faces, increases the reliability of structural interpretations, and enables reinforcement procedures to be optimized

Texto completoThis work aims an experimental characterization of the mechanical behaviour and failure by strain localization on a Vosges sandstone. The time evolution of strain localization has been characterized by full-field measurements. A new true-triaxial apparatus has been developed at Laboratoire 3SR (Grenoble), which enables the observation of the specimens during mechanical loading for application of digital image correlation (DIC). Tests have been performed in plane strain compression (confining pressure from 20 to 50 MPa). The transition from diffuse to localised deformation regimes has been extensively studied. Then, a comparative analysis has been done between the strain fields (DIC) and microscope (SEM) observations to determine how closely the DIC fields are related to deformation mechanisms detected at the grain scale. Finally, a theoretical bifurcation analysis is presented to compare the experimental observations of shear bands with strain localization prediction

Texto completoHoy en día, es difícil para un grupo rock emergente surgir dentro del mercado de la música nacional, debido a que las influencias extranjeras dominan la industria, y al tener más recursos, pueden llegar de una manera mucho más eficaz a su público objetivo. Además, el mercado nacional de la música es mayormente cerrado y exclusivo, lo que dificulta mucho el reconocimiento de éstas bandas por los medios tradicionales de información, radio, tv y periódicos, lo que conlleva que los grupos centren su difusión y promoción principalmente por internet a través de las redes sociales y por las tocatas o conciertos en vivo. En la constante e incansable lucha contra la piratería y el surgimiento de diversos streaming de reproducción online, los grupos musicales emergentes no centran sus ingresos en la propia venta de su música, lo que los lleva a la necesidad de la creación de una estética visual, ya sea en los afiches y difusión web o en las propuestas escenográficas de sus tocatas, para el posterior reconocimiento y surgimiento dentro del mercado de la música. Dentro de éste marco, Aytona, un grupo de rock-pop originario de Santiago, planea insertarse dentro de la nueva música nacional, sin embargo en la actualidad, carecen de una identidad visual que los identifique y represente. La necesidad de ésta investigación surge en la creación de un plan de comunicación visual y escenográfica para Aytona que se base en el concepto central de la banda -la idea de estética de video juego de 8-bit-, y que en el desarrollo de la memoria de Título se represente en la reconstrucción de su página web, difusión de material online y, en cuanto a la escenografía, a través del VJing -composiciones visuales en vivo- como una nueva perspectiva en las tocatas en vivo de la música rock.

Texto completoThe rock images of the central Sahara have suffered from the historical and human context of their discovery and then from both their scientific management and their heritage management. Their abundance and the difficulties of the Saharan field have been and are still negative factors, but the lack of knowledge from which these productions of prehistoric cultures are still suffering more than a century and a half after their discovery, clearly falls to those studying them in the past and present. Even if we admire these images for their aesthetic qualities, these form an integral part of the archaeological remains and should be studied as such. Nowadays, the digital and computerised tools enable us, firstly, to quantitatively and qualitatively improve their documentation thanks to image enhancement software used for the recording and the tracing; secondly, to more objectively investigate these artefacts by using other effective data-analysis tools and methods thanks to which their stylistic differences can be highlighted. The application of the processes developed in this research to several adorned walls at the Sefar site, an emblematic area of the Tasīli-n-Ăjjer (Algeria), shows that the use of these tools, supported by rigorous theoretical and methodological basis, allows us to offer a new approach to these rock images, more appropriate to their characteristic of being scientific data
