Este texto é uma reflexão sobre os pressupostos que fizeram parte do meu processo de trabalho em artes visuais nos últimos anos e que continuam em desenvolvimento. A investigação parte de um pressuposto gerado de três séries de trabalhos, Bambu, bambuí, Sobreposições e Imersão Rio, que se conectam por um deslocamento entre três ambientes: paisagem, ateliê e galeria. Ao rastrear as influências recorrentes em minha produção, acesso um momento histórico específico por onde permeio minha pesquisa e procuro compreender os procedimentos, ações e estratégias que compõem minha poética artística
This text is a reflection on the presuppositions which were part of my process of work on visual arts in the recent years and continue to develop. The research starts on a presupposition generated by three series of works, Bambu, bambuí, Sobreposições and Imersão Rio, which are connected by a displacement from three environments: landscape, studio and gallery. By tracking the recurrent influences in my production, I access the specific historical moment where I permeate my research and I try to understand the procedures, actions and strategies that compose my artistic poetics

Geological Carbon Storage (GCS) is considered as one of the key techniques to reduce the rate of atmospheric emissions of CO2 and thereby to contribute to controlling the global warming. A successful application of a GCS project requires the capability of the formation to trap CO2 for a long term. In this context, processes related to CO2 trapping and also possible leakage of CO2 to the near surface environment need to be understood. The overall aim of this thesis is to understand the flow and transport of CO2 through porous media in the context of geological storage of CO2. The entire range of scales, including the pore scale, the laboratory scale, the field experiment scale and the industrial scale of CO2 injection operation are addressed, and some of the key processes investigated by means of experiments and modeling. First, a numerical model and laboratory experimental setup were developed to investigate the CO2 gas flow, mimicking the system in the near-surface conditions in case a leak from the storage formation should occur. The system specifically addressed the coupled flow and mass transport of gaseous CO2 both in the porous domain as well as the free flow domain above it. The comparison of experiments and modelling results showed a very good agreement indicating that the model developed can be applied to evaluate monitoring and surface detection of potential CO2 leakage. Second, the field scale CO2 injection test carried out in a shallow aquifer in Maguelone, France was analyzed and modeled. The results showed that Monte Carlo simulations accounting for the heterogeneity effects of the permeability field did capture the key observations of the monitoring data, while a homogeneous model could not represent them. Third, a numerical model based on phase-field method was developed and model simulations carried out addressing the effect of wettability on CO2-brine displacement at the pore-scale. The results show that strongly water-wet reservoirs provide a better potential for the dissolution trapping, due to the increase of interface between CO2 and brine with very low contact angles. The results further showed that strong water-wet conditions also imply a strong capillary effect, which is important for residual trapping of CO2. Finally, numerical model development and model simulations were carried out to address the large scale geological storage of CO2 in the presence of impurity gases in the CO2 rich phase. The results showed that impurity gases N2 and CH4 affected the spatial distribution of the gas (the supercritical CO2 rich phase), and a larger volume of reservoir is needed in comparison to the pure CO2 injection scenario. In addition, the solubility trapping significantly increased in the presence of N2 and CH4.

Based on the substantial body of literature from research, theory, and policy discussion, the hypothesized relationships in this study were that violations of court would be more likely to be observed among status than other referrals, particularly among runaway cases, and that both relationships would be more pronounced for girls. I examined data from a large urban court in which there are many services and routinized processing of a lot of juveniles. The results fail to support any of the four hypothesized relationships.

O corpo é ser: diários sobre a distância é uma investigação que parte da condição do deslocamento/desterro a caminho de discussões que interrelacionam dados inerentes ao meu processo de criação a abordagens teóricas e artísticas. Tomando a crítica de processo, proposta por Cecilia Salles, como metodologia, faço um resgate de materias de registro que apontam para trabalhos que desenvolvi entre 2009 e 2013, apresentados no corpo do texto. A estrutura da dissertação se divide em dois cadernos. O primeiro contém um embate das referências teóricas e processuais relacionadas ao contexto do deslocamento e da condição de estrangeiro e é dividido em três capítulos que discutem: a viagem como possibilidade artística, a memória e os diários como aparatos processuais e o corpo em ações performativas. O segundo caderno trata-se de um livro-processo que abriga uma coleção de vestígios que deflagram os caminhos tateados para a construção desta pesquisa.
The work \"O corpo é ser: diários sobre a distância\" is an investigation that starts from the condition of displacement/exile and moves into an argumentation that correlates a theoretical research to data about my creative process. Guided by the theoretical approach called crítica de processo, as proposed by Cecilia Salles, I recover documentary material within the work I developed as a photographer from 2009 to 2013 and the selection is presented within the text. The essay is divided in two books. The first book contains a clash of theoretical frameworks and procedures about the concept of displacement and the foreigner condition, this portion is divided in three chapters in which I discuss: the trip as an artistic experiment, memory and the making of diaries as procedural apparatus, and the body in performance. The second book is a process-book containing a collection of traces that trigger paths groped to build this research.

Abstract I. Introduction a. Thesis statement: What is the process for modeling a stylized character and how does this differ from a semi-realistic character? b. Expanded thesis statement: The two styles differ from start to finish in a variety of ways. I believe that semi-realistic characters require more source material when drawing and modeling; however stylized characters require a different level of creativity and artistic ability in creation. Modeling semi-realistic characters will be more dependent on source images while stylized characters may require special attention with non-standard texture, style, etc. Rendering techniques will also differ when it goes to presenting the final polished versions with the stylized character focusing on rendering styles that flatten the character while the semi realistic character will require rendering techniques that make it seem more real visually.

Identity always presupposes a sense of location and a relationship with others and the representation of identity most often occurs precisely at the point when there has been a displacement (Bhabha cited in Papastergiadis 1995:17, emphasis added). In this study I focus on the condition of displacement, placing emphasis on the disjunctures of identity arising from temporal and physical dislocations and relocations in historical and postapartheid South African contexts. Displacement, and the attendant senses of dislocation and alienation it may evoke, is explored with reference to three selected female personae. For each persona, displacement is shown to provoke transmutations in subjectivity and identity, resulting in disjunctive identities and relationships with place. Their individual narratives raise questions around the consequences of displacement for a sense of (un)belonging and the (re)making of identities across geographical, cultural, temporal, ethnic and environmental borders. The pivotal role displacement plays in the processes of formation and transformation of subjectivity and identity is foregrounded. Familial histories of diasporic displacement, together with colonial legacies that have shaped my subject position as a white, middle-class, female South African woman, are interlaced with a recounting of personal experience of displacement in postapartheid South Africa. This personal sense of displacement, experienced between the years 2000 to 2006, is extended to a discussion on what is argued to be collective forms of white, English-speaking South Africans’ dislocation during the same time period. I suggest that their sense of displacement was experienced in relation to the uncertainty of their subject positions in postapartheid South Africa. In the practical and theoretical components of the degree, I consider how the three personae’s subjectivities are practiced and lived from their different space-time continuums. This exploration prompts further questions around how the effects of displacement on subjectivity and new identity formations are contingent upon each persona’s relation to the Other of colonial discourse, or the other-strangerforeigner within. Although there are marked differences between their colonial, diasporic and postcolonial contexts, a central theme that underpins the study is that the three conditions of displacement are linked by disjunctures arising from processes of dislocation, alienation, relocation and adaptation. Each persona’s epistemological reality is shown to comprise multiple ambivalences and ambiguities, and is marked by processes of cultural contestation and inner conflict. Their ambivalences and ambiguities encompass slippages between positions of inclusion and exclusion; insider and outsider; inhabitant and immigrant; alienation and belonging; placelessness and locatedness; homely and unhomely that the experience of uprooting and relocating foregrounds. While displacement is understood in terms of trauma and conflict, this condition is also regarded as a generative space of possibility for the emergence of new identity formations. Using my experiences of self-transformation and renegotiation of my identity through processes of cultural contact and exchange as a departure point, I consider ways in which collective white, English-speaking South Africans’ cultural identities are being reformulated, renegotiated or ‘hybridised’ in postapartheid South Africa as a transforming, postcolonial society.

The main goal of this thesis is to deposit metal particles on the surface of 2D nanoplatelets using a controlled cementation process. As a proof of concept, copper (Cu) and Graphene Nanoplatelets (GNP) were chosen as the representative metal and 2D nanoplatelets, respectively. Specific goals of this study include depositing nanometer scale Cu particles on the surface of GNP at a low concentration (approximately 5 vol.%) while maintaining clustering and impurities at a minimum. Parametric studies were done to attain these goals by investigating various metallic reducer types and morphologies, GNP surface activation process, acid volume % and copper (II) sulfate concentrations. Optimal conditions were obtained with Mg ribbon as a reducer, 3 minutes of activation, 1 vol.% of acetic acid and 0.01 M CuSO4. The GNP-Cu powder synthesized in this work is a precursor material to be consolidated via spark plasma sintering (SPS) to make a nacre-like, layered structure for future studies.

This thesis presents results of a successful simulation study using CO2-EOR technique to enable production from an offshore heavy oil field, named here as Omega, which is located offshore West Africa at a water depth around 2000 m. The findings and contributions to knowledge are outlined below: 1. Long distance CO2 transportation offshore – The solution to the space and weight constraints offshore with respect to CO2-EOR, is a tie-back via long distance CO2 dense phase transportation from onshore to offshore. 2. Cold heavy oil production (CHOP) using CO2-EOR technique - Based on conditions investigated, Miscible Displacement was found to be more efficient for deepwater production. However, Immiscible Displacement can offer greater reliability with regards to CO2 sequestration. 3. CO2 sequestration during CHOP using CO2-EOR technique – Lower CO2 may be released post start-up operation, followed by gradual decline of CO2 retention after the production peak. CO2 retention increases with increasing reservoir pressure, starting with 17.7 % retention at 800 psig to 32.8 % at 5000 psig, based on peak production analysis. 4. Techno-economic Evaluation – Miscible displacement is asssociated with higher cash flow stream that extend throughout the lifetime of the asset due to continuous production while Immiscible Displacement has a longer payback period (in order of 22 years) due to the time lag between the CO2 injection and the incremental heavy oil production. 5. Mathematical Modelling – Improved mathematical models based on existing theories are proposed, to estimate the CO2 requirement and heavy oil production during CHOP using CO2-EOR technique, and to provide an operating envelope for a wide range of operating conditions. As part of further work, the proposed models will require more refinement and validation across a broad range of operating conditions, could be adapted and modified to increase its predictive capability over time.

One of the characteristics that distinguishes living things from non-living things is motility. On the cellular level, the motility or non-motility of different types of cells can be life building, life-saving or life-threatening. A thorough study of cell motion is needed to help understand the underlying mechanisms that enhance or prohibit cell motion. We introduce a discrete centroid model of cell motion in the context of a generalized random walk. We find an approximation for the theoretical mean square displacement (MSD) that uses a subset of the state space to estimate the MSD for the entire space. We give some intuition as to why this is an unexpectedly good estimate. A lower and upper bound for the MSD is also given. We extend the centroid model to an ODE model and use it to analyze the distribution of focal adhesion (FA) lifetimes gathered from experimental data. We found that in all but one case a unimodal, non-symmetric gamma distribution is a good match for the experimental data. We use a detach-rate function in the ODE model to determine how long a FA will persist before it detaches. A detach-rate function that is dependent on both force and time produces distributions with a best fit gamma curve that closely matches the data. Using the data gathered from the matching simulations, we calculate both the cell speed and mean FA lifetime and compare them. Where available, we also compare this relationship to that of the experimental data and find that the simulation reasonably matches it in most cases. In both the simulations and experimental data, the cell speed and mean FA lifetime are related, with longer mean lifetimes being indicative of slower speeds. We suspect that one of the main predictors of cell speed for migrating cells is the distribution of the FA lifetimes.

The present work is a monographic study about the visual poetic of the artist Carlos Vergara, in which I propose an approach to his process of creation. To do this, I adopt three works at the exhibition Sacred Heart - San Miguel Mission, from December 23, 2008 to March 15, 2009 at the Art Museum of Rio Grande do Sul Ado Malagoli, in Porto Alegre, RS. The aforementioned works are: St. Michael - Sacred Heart (Monotype and paint on raw canvas), SM 4 (3D lenticular) and San Miguel - Floor VI (Monotype on raw canvas). In addition, two issues influenced the development of this research: the physical displacement and the subsequent appropriation of space by the artist in his creative process. Thus, the problem proposed in this research is: How is the displacement of the visible / invisible in the work of Carlos Vergara? That is, as the physical displacement of the artist - the action of visiting certain places - and the possible shifts contained in his poetry, a sign / signs / signals from these places, relating to both in their process of creation. The work is divided into three chapters, with the first chapter deals with the person Vergara, in which the focus is the direction taken by the artist and his influences. The second chapter provides a chronological overview of the artist from the 1960s to its current production, which demarcated their production in the context of contemporary Brazilian art. Finally in the third chapter, in house procedures adopted by the artist in the preparation of the artwork from the works already mentioned, which emphasizes the concept of displacement, incorporating how the artist perceives the issue. The approach to the creative process led to confirmation of existing dislocations, confirming its nature of mobility, but also the possible variables of the visible, these issues often addressed in the production and reflection of contemporary art.
Este trabalho consiste no estudo da poética visual do artista Carlos Vergara, no qual se propôs uma aproximação ao processo construtivo de três obras apresentadas na Exposição Sagrado Coração Missão de São Miguel, no período de 23 de dezembro de 2008 a 15 de março de 2009, no Museu de Arte do Rio Grande do Sul Ado Malagoli, em Porto Alegre, RS. As mencionadas obras são: São Miguel - Sagrado Coração, (Monotipia e pintura sobre lona crua), S.M. 4 (3D lenticular) e São Miguel - Piso VI (Monotipia sobre lona crua). Além disso, duas questões permearam o desenvolvimento da pesquisa: o deslocamento físico e a conseqüente apropriação do espaço pelo artista em seu processo criativo. Com isso, a problemática proposta foi a seguinte: De que maneira ocorre o deslocamento do visível/invisível na obra de Carlos Vergara? Ou seja, como o deslocamento físico do artista ação de visitamento a determinados lugares , e os possíveis deslocamentos contidos na sua poética, enquanto vestígio/indícios/sinais desses lugares, incidem simultaneamente em seu processo de criação. O trabalho está dividido em três capítulos, sendo que o primeiro capítulo versa sobre a pessoa Vergara, no qual o enfoque é dado aos rumos tomados pelo artista e suas influências. O segundo capítulo oferece um apanhado cronológico de obras do artista desde a década de 1960 até sua produção atual, onde se demarcou sua produção no contexto da arte brasileira contemporânea. Finalmente no terceiro capítulo, adentro nos procedimentos adotados pelo artista na elaboração da obra de arte, a partir das obras já nomeadas, no qual se destaca o conceito de deslocamento, incorporando o modo como o próprio artista percebe essa questão. A aproximação ao seu processo criativo permitiu a constatação dos deslocamentos existentes, atestando seu caráter de mobilidade, como também das possíveis variáveis do visível, questões essas abordadas na produção e reflexão da arte contemporânea.

This thesis conceptualises the job transition as a continuous process in the context of organisational downsizing and restructuring. It argues that the policy and research related to re-employment following job loss, organisational downsizing and relevant labour market interventions remains disconnected from, and hence underemphasises, the sequential and cumulative nature of the transition process while also focussing disproportionately on modifying individual behaviour and action. This study explores the intersection and overlap in factors, actions and decisions made by actors in each part of the transition process to better understand the dynamic nature of job transition and its implications for re-employment and future job quality. This research considers job transition from two forms of displacement – job displacement and worker displacement. It comprises a cross-national comparative study of displacement from public sector work in Ontario, Canada and Scotland, UK. Forty expert and stakeholder interviews were carried out addressing different aspects of job transition, targeting academic and policy experts, employers/senior managers, union representatives and labour market programme service providers. Furthermore, 38 semi-structured work history interviews were conducted with displaced workers along with a follow-up survey. This research argues that downsizing policy and labour market interventions appear to view any job as a better outcome than redundancy. Where organisational policies maintain employment, the emphasis is on maintaining extrinsic features of work. Through practices like salary protection and lateral transfers, good quality work beyond equivalent remuneration is a bi-product rather that a central consideration. The study finds that individuals, faced with particular processes and limited information, modify their behaviour to protect valued aspects of work including, but not limited to, extrinsic job factors. Conceptually, this research contributes to knowledge on job loss and re-employment, organisational downsizing practice and job quality. Empirically, it contributes to debates on public sector restructuring following the Great Recession of 2008.

In this essay, the novel Beloved, by Toni Morrison is observed using a working psychoanalytical approach. Story is observed as an important factor in engaging the reader on a personal level with the experience of trauma. By surveying Morrison’s use of imagery and language, this essay will examine how Morrison employs literary methods that imitate the psychological processes regarding how trauma is communicated to the waking state from the unconscious. The resulting testimony of the novel that arises as the result of these processes is also observed. This essay concludes that Morrison’s use of these literary methods functions to obligate the reader to involve themselves in the process of trauma and its resolution.

The objective of this study is to model and analyze a three dimensional single riveted lap joint (with and without a crack). By using finite element method, stress and fracture analyses are carried out under both the residual stress field and external tensile loading. Using a two step simulation, riveting process and subsequent tensile loading of the lap joint are simulated to determine the residual and overall stress state. Residual stress state due to riveting is obtained by interference and clamping misfit method. By employing different interference and clamping misfit values, the effects of riveting process parameters on stress state are examined. Two cracks namely the semi elliptical surface crack at faying surfaces of plates and the quarter elliptical corner crack at rivet hole are the most widely observed crack types in riveted joints. Fracture analysis of cracked riveted joints is carried out by introducing these two crack types to the outer plate at a plane perpendicular to the loading. The mixed mode stress intensity factors (SIFs) and energy release rates (G) around the crack front are obtained by using displacement correlation technique (DCT). Effects riveting process parameters (interference and clamping ratios) and geometrical parameters (crack shape and size) on fracture parameters are studied. The stress intensity factor solutions presented herein could be useful for correlating fatigue crack growth rates, fracture toughness computation, and multiple site damage (MSD) analysis in aircraft bodies.

In recent years, the number of renovations of apartment buildings from the Swedish million homes programme has increased significantly. The renovations have resulted in major increases in standard of the apartments built half a century ago, and has thus resulted in substantial rent increases. In the past, the so called “Allbolag” prevented private property owners from charging rents above market rents, since the public property sector was rent normative. Since this law was amended in 2011, a greater interest was shown in the renovation of million programme apartment buildings since extensive renovations got more profitable than ever before. With a major rent increase as a result of the renovations it is a hot topic in the Swedish housing policy debate. Opinions differ in the debate where property owners see opportunities for increased value and profit in the properties, while the individual tenant has to deal with major rent increases, which in some cases rises up towards 80 percent. The tenants affected by the extensive renovations, and thus also the significant rent increases that follow, are affected not only economically but also on a personal and social level. People living in million programme apartments are fully aware of the consequences of a major refurbishment, and they also know that they have no power to influence the outcome or extent of the actions. This causes mental and, in some cases, physical stress on the individuals who have to live with the knowledge of that they eventually might be forced to move from their homes because of their inability to pay the rent. Your home is a hub for everything that is essential in life and it is where social networks of family, relatives and friends, work, school, health care and more are maintained, but when your home ceases to be a place where you can feel safe and secure it affects every factor in these networks. The purpose of this paper is to describe and explain how a rent-setting process after an extensive renovation of Swedish million programme homes is conducted, and to describe how the affected tenants' well-being, in terms of anxiety and insecurity, are affected by this process. To achieve the purpose, we have conducted a qualitative survey through personal interviews which covers two tenants both of whom are affected by the problem, and two individuals who, on a daily basis, work with this problem and are well versed in the subject. Results that emerged from the study is that the rent setting system in the case of extensive renovations are not adapted for today's housing market, and that it therefore poses a problem. Tenants are virtually powerless when it comes to renovations of their apartments and their choices are to either keep their home and try to cope with the new rent, or move to a cheaper area which has not yet been renovated. The entire process, starting when the tenant learns about the planned renovation, until the project is completed has been shown to cause psychological problems for the individual, no matter if he chooses to stay put or move away. The study also shows that tenants undergoing a renovation process feel insecure in their home and that they also feel anxious and worried about the future of their living situation.
På senare år har antalet renoveringar av flerbostadshus från miljonprogrammet ökat markant. Renoveringarna har medfört stora standardhöjningar i de över 50 år gamla lägenheterna, och har därmed resulterat i kraftiga hyreshöjningar. Tidigare hindrade Allbolagen privata fastighetsägare från att ta ut oskäligt stora hyresbelopp eftersom de allmännyttiga fastighetsbolagen då var hyresnormerande, men sedan denna lag ändrades år 2011 har ett större intresse för renoveringar av miljonprogrammets flerbostadshus väckts. Omfattande renoveringar är i dagsläget än mer lönsamma än tidigare, och med kraftiga hyreshöjningar som följd är det ett hett debatterat ämne i media. Åsikterna går isär i debatten där fastighetsägare ser möjligheter till ökat värde och vinst i fastigheterna, medan den enskilde individen tvingas på hyreshöjningar som i vissa fall blir så kraftiga som upp emot 80 procent. De hyresgäster som berörs av omfattande renoveringar, och därmed också de markanta hyreshöjningar som följer av dem, påverkas inte bara ekonomiskt utan även på ett personligt och socialt plan. Boende i miljonprogramslägenheter vet vad konsekvenserna av en omfattande renovering blir, och de vet också att de själva inte har någon chans att påverka resultatet eller omfattningen av den. Detta innebär en psykisk och, i vissa fall, fysisk påfrestning på individerna som tvingas leva med vetskapen om att de så småningom kan tvingas flytta ifrån sina hem på grund av oförmåga att betala hyran. Hemmet är en knytpunkt för allt som är centralt i livet och det är därifrån kontaktnätet till familj, släkt och vänner, arbete, skola, sjukvård med mera utgår, och när hemmet upphör att vara en plats där man kan känna sig trygg och säker i sin tillvaro påverkar det samtliga faktorer i detta kontaktnät. Syftet med denna uppsats är att beskriva och förklara hur en hyressättningsprocess efter en omfattande renovering gällande flerbostadshus från miljonprogrammet går till, samt redogöra för hur de berörda hyresgästernas välmående, sett till oro och otrygghet, påverkas av denna process. För att uppnå syftet har vi genomfört en kvalitativ undersökning vilken genomfördes med hjälp av personliga intervjuer. Undersökningen omfattar två hyresrättsinnehavare som själva är drabbade av problemet samt två personer som dagligen arbetar med detta problem och är väl insatta i ämnet. Resultat som framkommit är att hyressättningssystemet vid omfattande renoveringar inte är anpassat för dagens bostadsmarknad och att det därmed medför problem. Hyresgäster är i stort sett maktlösa när det kommer till renoveringar av deras lägenheter och deras val står mellan att bo kvar och försöka klara av den nya hyran, eller flytta till ett billigare område som ännu inte renoverats. Hela processen från det att hyresgästen får reda på renoveringen tills projektet är genomfört har visat sig medföra psykiska problem för individen oavsett vad denne väljer att göra. Studien visar på att hyresgäster som genomgår en renoveringsprocess känner sig otrygga i sin hemvist och upplever en oro över hur deras framtid kommer att se ut.

To minimize the complexity of existing process control valves, the authors derived a new control valve design by functional separation and functional integration of functions. One key element of this new valve design is the functional integration of teh actuator into the valve´s throttle. A hydraulic swivel motor is operated with the process fluid, in this case water. The pressure difference to operate the motor comes from the valve itself. Within this paper we present the control valve design and show in detail how we used the Fail-Early design method to develop the hydraulic swivel motor. The construction is discussed using the experience from manufacturing the prototype and the first exp erimental results are shown. The experiments yield, that the swivel motor principle is promising. Finally, the next development issues are discussed.

Cette étude porte sur deux problèmes issus du processus de fabrication des imprimantes à jet d'encre. Dans le cadre du premier problème, on s'est intéressé à l'étude de l'évolution d'une interface de deux fluides sous l'influence uniquement des forces de capillarité. Un théorème d'existence et d'unicité globale en temps pour des données initiales petites est présenté. Le deuxième problème porte sur la modélisation du comportement d'un fluide contenu dans une enceinte soumise à des vibrations et comportant de petits orifices alignés. En utilisant un développement asymptotique en puissance de la plus petite dimension de l'enceinte et incluant les termes de couche-limite, on obtient la convergence de la solution du problème tridimensionnel, ainsi que la convergence de la solution du problème homogénéisé tridimensionnel vers la solution d'un même problème bidimensionnel. Des problèmes de contrôle frontière sont présentés. Une série de simulations numériques sert à illustrer les résultats théoriques précédents. Une autre série permet de comparer les résultats théoriques aux résultats expérimentaux

Le regioni idrotermali sono interessate da una grande varietà di fenomeni naturali, tra cui episodi di rigonfiamento e subsidenza del suolo. Tra di esse, le caldere consentono di studiare le interazioni tra i processi magmatici e le dinamiche dei fluidi di cui sono imbevute le rocce porose nella crosta superficiale. Un'area idrotermale soggetta a instabilità periodiche è la caldera dei Campi Flegrei, nell'Italia meridionale. Una delle crisi più recenti, oggetto di numerosi studi e ricerche, ha avuto luogo nel biennio 1982-84. La tesi si propone di sviluppare un modello di sorgente deformativa che prevede una regione termo-poro-elastica inclusa in un solido poro-elastico semi-illimitato, nel caso in cui questa regione abbia forma cilindrica e subisca cambiamenti di temperatura e pressione di poro al suo interno. Viene fornita una soluzione semi-analitica per spostamenti e sforzi così generati all'interno e all'esterno della sorgente deformativa, e i risultati sono paragonati a quelli ottenuti tramite un approccio completamente numerico, insieme a quelli di altri tre modelli. Lo spostamento verticale risultante alla superficie libera è in buon accordo con quello prodotto dal modello di Mogi, e riproduce il pattern di deformazione verticale osservato presso i Campi Flegrei durante la crisi del 1982-84. Tuttavia, vi sono differenze nelle ampiezze delle componenti dello spostamento tra il nostro modello e gli altri due considerati. I risultati per il campo di sforzi sul piano mediano della sorgente indicano un regime compressivo al suo interno, mentre si evidenzia un regime distensivo nella regione sovrastante, e un regime trascorrente nella regione esterna del semispazio. Questo è in accordo con la distribuzione eterogenea dei meccanismi focali ottenuti dai dati sismologici relativi allo stesso episodio presso i Campi Flegrei. Alla fine dell’opera, sono discussi i limiti di applicabilità del modello e ne sono indicati alcuni possibili sviluppi ulteriori.

Resumo: As propriedades que atuam no deslizamento lateral de um equipamento de arrasto em áreas agrícolas, variam amplamente, indo desde as relacionadas ao solo até aos parâmetros envolvidos no sistema trator-equipamento que podem afetar o deslocamento lateral. O objetivo com o estudo foi mensurar o erro de paralelismo do conjunto trator-protótipo em função de diferentes raios de curvatura, larguras de bitola e comprimentos do cabeçalho de um protótipo de arrasto, além de avaliar a variabilidade do processo por meio do Controle Estatístico do Processo. Os testes foram realizados em área experimental da Universidade Estadual Paulista (Unesp), Faculdade de Ciências Agrárias e Veterinárias, Câmpus de Jaboticabal. Foi adaptado o chassi de uma semeadora-adubadora, que possibilitasse mudança no comprimento do cabeçalho e variação na largura da bitola do equipamento, o qual denominamos protótipo de arrasto. O delineamento experimental foi o inteiramente casualizado, em esquema fatorial 5x4x15, com cinco comprimentos do cabeçalho e quatro larguras de bitola do protótipo em quinze raios de curvatura médio. A medição do paralelismo entre as passadas do conjunto trator-protótipo foi obtida por meio de um instrumento desenvolvido que denominamos “pirulito” e com o auxílio de uma trena. Nos raios de 16,4 m e de 20 m os erros de paralelismo são maiores, em todas as bitolas e vão diminuindo à medida que se aumenta a circunferência do raio.

Abstract: The properties that act on the lateral sliding of a trailed equipment in agricultural areas, change widely, ranging from those related to the soil to the parameters involved in the tractor-equipment system that can affect lateral displacement. The objective of the study was to measure the parallelism error of the tractor-prototype set as a function of different curvature radius, the widths of the gauge and the lengths of the header of a drag prototype, in addition, the evaluating process of the variability through the Statistical Process Control. The tests were carried out in an experimental area at the São Paulo State University (Unesp), School of Agricultural and Veterinary Sciences, Campus of Jaboticabal. The chassis of a seeder-fertilizer was adopted, so that it would allow a change in the length of the header and a variation in the width of the gauge of the equipment, which we call the trailed prototype. The experimental design was entirely randomized, in a 5x4x15 factorial scheme, with five header lengths and four widths of gauge of the prototype in fifteen average curvature radius. The measurement of the parallelism between the steps of the tractor-prototype set was obtained by using an instrument that we call “lollipop” and with the help of a measuring tape. In the 16.4 m and 20 m radius the parallelism errors were greater than the other gauges, and it decreased as the radius circumference increased. The header length of 2.40 m, when compared to the others, obtained t... (Complete abstract click electronic access below)

Sob certas hipóteses simplificadoras, o modelo matemático que descreve o escoamento de água e óleo em reservatórios de petróleo pode ser representado por um sistema não linear de Equações Diferenciais Parciais composto por uma equação elíptica de pressão (fluxo) e uma equação hiperbólica de saturação (transporte). Devido a complexidades na modelagem de ambientes deposicionais, nos quais são incluídos camadas inclinadas, canais, falhas e poços inclinados, há uma dificuldade de se construir um modelo que represente adequadamente certas características dos reservatórios, especialmente quando malhas estruturadas são usadas (cartesianas ou corner point). Além disso, a modelagem do escoamento multifásico nessas estruturas geológicas incluem descontinuidades na variável e instabilidades no escoamento, associadas à elevadas razões de mobilidade e efeitos de orientação de malha. Isso representa um grande desafio do ponto de vista numérico. No presente trabalho, uma formulação fundamentada no Método de Volumes Finitos é estudada e proposta para discretizar as equações elíptica de pressão e hiperbólica de saturação. Para resolver a equação de pressão três formulações robustas, com aproximação dos fluxos por múltiplos pontos são estudadas. Essas formulações são abeis para lidar com tensores de permeabilidade completos e malhas poligonais arbitrárias, sendo portanto uma generalização de métodos mais tradicionais com aproximação do fluxo por apenas dois pontos. A discretização da equação de saturação é feita com duas abordagens com característica multidimensional. Em uma abordagem mais convencional, os fluxos numéricos são extrapolados diretamente nas superfícies de controle por uma aproximação de alta resolução no espaço (2ª a 4ª ordem) usando uma estratégia do tipo MUSCL. Uma estratégia baseada na Técnica de Mínimos Quadrados é usada para a reconstrução polinomial. Em uma segunda abordagem, uma variação de uma esquema numérico Verdadeiramente Multidimensional é proposto. Esse esquema diminui o efeito de orientação de malha, especialmente para malhas ortogonais, mesmo embora alguma falta de robustez possa ser observada pra malhas excessivamente distorcidas. Nesse tipo de formulação, os fluxos numéricos são calculados de uma forma multidimensional. Consiste em uma combinação convexa de valores de saturação ou fluxo fracionário, seguindo a orientação do escoamento através do domínio computacional. No entanto, a maioria dos esquemas numéricos achados na literatura tem aproximação apenas de primeira ordem no espaço e requer uma solução implícita de sistemas algébricos locais. Adicionalmente, no presente texto, uma forma modificada desses esquemas “Verdadeiramente” Multidimensionais é proposta em um contexto centrado na célula. Nesse caso, os fluxos numéricos multidimensionais são calculados explicitamente usando aproximações de alta ordem no espaço. Para o esquema proposto, a robustez e o caráter multidimensional também leva em conta a distorção da malha por meio de uma ponderação adaptativa. Essa ponderação regula a característica multidimensional da formulação de acordo com a distorção da malha. Claramente, os efeitos de orientação de malha são reduzidos. A supressão de oscilações espúrias, típicas de aproximações de alta ordem, são obtidas usando, pela primeira vez no contexto de simulação de reservatórios, uma estratégia de limitação multidimensional ou Multidimensional Limiting Process (MLP). Essa estratégia garante soluções monótonas e podem ser usadas em qualquer malha poligonal, sendo naturalmente aplicada em aproximações de ordem arbitrária. Por fim, de modo a garantir soluções convergentes, mesmo para problemas tipicamente não convexos, associados ao modelo de Buckley-Leverett, uma estratégia robusta de correção de entropia é empregada. O desempenho dessas formulações é verificado com a solução de problemas relevantes achados na literatura.
Under certain simplifying assumptions, the problem that describes the fluid flow of oil and water in heterogeneous and anisotropic petroleum reservoir can be described by a system of non-linear partial differential equations that comprises an elliptic pressure equation (flow) and a hyperbolic saturation equation (transport). Due to the modeling of complex depositional environments, including inclined laminated layers, channels, fractures, faults and the geometrical modeling of deviated wells, it is difficult to properly build and handle the Reservoir Characterization Process (RCM), particularly by using structured meshes (cartesian or corner point), which is the current standard in petroleum reservoir simulators. Besides, the multiphase flow in such geological structures includes the proper modeling of water saturation shocks and flow instabilities associated to high mobility ratios and Grid Orientation Effects (GOE), posing a great challenge from a numerical point of view. In this work, a Full Finite Volume Formulation is studied and proposed to discretize both, the elliptic pressure and the hyperbolic saturation equations. To solve the pressure equation, we study and use three robust Multipoint Flux Approximation Methods (MPFA) that are able to deal with full permeability tensors and arbitrary polygonal meshes, making it relatively easy to handle complex geological structures, inclined wells and mesh adaptivity in a natural way. To discretize the saturation equation, two different multidimensional approaches are employed. In a more conventional approach, the numerical fluxes are extrapolated directly on the control surfaces for a higher resolution approximation in space (2nd to 4th order) by a MUSCL (Monotone Upstream Centered Scheme for Conservation Laws) procedure. A least squares based strategy is employed for the polynomial reconstruction. In a second approach, a variation of a “Truly” Multidimensional Finite Volume method is proposed. This scheme diminishes GOE, especially for orthogonal grids, even though some lack of robustness can be observed for extremely distorted meshes. In this type of scheme, the numerical flux is computed in each control surface in a multidimensional way, by a convex combination of the saturation or the fractional flow values, following the approximate wave orientation throughout the computational domain. However, the majority of the schemes found in literature is only first order accurate in space and demand the implicit solution of local conservation problems. In the present text, a Modified Truly Multidimensional Finite Volume Method (MTM-FVM) is proposed in a cell centered context. The truly multidimensional numerical fluxes are explicitly computed using higher order accuracy in space. For the proposed scheme, the robustness and the multidimensional character of the aforementioned MTM-FVM explicitly takes into account the angular distortion of the computational mesh by means of an adaptive weight, that tunes the multidimensional character of the formulation according to the grid distortion, clearly diminishing GOE. The suppression of the spurious oscillations, typical from higher order schemes, is achieved by using for the first time in the context of reservoir simulation a Multidimensional Limiting Process (MLP). The MLP strategy formally guarantees monotone solutions and can be used with any polygonal mesh and arbitrary orders of approximation. Finally, in order to guarantee physically meaningful solutions, a robust “entropy fix” strategy is employed. This produces convergent solutions even for the typical non-convex flux functions that are associated to the Buckley-Leverett problem. The performance of the proposed full finite volume formulation is verified by solving some relevant benchmark problems.

Дисертація присвячена вивченню і встановленню комплексних закономірностей деформацій земної поверхні та масиву слабометаморфізованих гірських при розробці пологих вугільних пластів. Встановлено, що характер розподілу горизонтальних зрушень і деформацій, залежить від глибини підробки, напряму руху очисного вибою, ступеню розвитку реологічних процесів і геометричних параметрів зон зрушення над очисною виробкою. Формування горизонтальної і вертикальної складових вектора зрушення відбувається під впливом різних чинників, що не дозволяє використовувати загальні принципи їх прогнозування. Запропонований механізм формування горизонтальних зрушень і деформацій підроблюваного масиву і геометричні параметри зон зрушення над рухомим очисним вибоєм.

Диссертация посвящена изучению и установлению комплексных закономерностей деформирования земной поверхности и массива слабометаморфизованных горных при разработке пологих угольных пластов. В диссертации исследовано состояние изученности по выбранному направлению, в результате которого установлено, что процесс горизонтального деформирования земной поверхности для условий разработки угольных пластов в Западном Донбассе изучен недостаточно. Исследования процесса сдвижения горных пород немногочисленны, а методика прогнозирования сдвижений и деформаций подрабатываемого массива отсутствует. Незначительный интерес к горизонтальной составляющей вектора сдвижения является следствием существующего утверждения о пропорциональности величин вертикальных и горизонтальных сдвижений, выдвинутое Авершиным С.Г. Характер распределения этих величин в пределах полумульды по существующим представлениям одинаковый, что не подтверждается результатами инструментальных наблюдений. В результате производства комплекса инструментальных наблюдений за сдвижением земной поверхности и массива горных работ установлены закономерности характера их деформирования в различных горно-геологических условиях подработки и скоростях подвигания очистного забоя. Установлено, что характер распределения горизонтальных деформаций в главном сечении, параллельном направлению подвигания очистного забоя, зависит от глубины подработки, степени развития реологических процессов и геометрических параметров зон сдвижения над очистной выработкой. Полученная зависимость подтверждается результатами математического моделирования с применением переменных модулей, учитывающих изменение физико-механических свойств во времени. В плоском дне мульды сдвижения зафиксированы величины горизонтальных перемещений, значения которых для условий Западного Донбасса постоянны и равны 240 мм. В работе изучен механизм их образования вследствие процессов, происходящих на контакте зон повышенного и пониженного горного давления. На основе комплексного анализа сдвижений и деформаций земной поверхности и массива горных пород установлены геометрические параметры зон сдвижений над движущимся очистным забоем и после его остановки. Установлено, что при скоростях подвигания очистного забоя свыше 60 м/мес впереди него формируется область пониженных вертикальных напряжений. Геометрические параметры этой области и степень понижения напряжений зависят от скорости подвигания забоя. В результате комплексного анализа параметров деформирования земной поверхности и подрабатываемого массива разработана методика определения величин прироста горного давления в произвольных точках зоны повышенного горного давления. Предложена методика прогнозирования горизонтальных сдвижений и деформаций земной поверхности и массива горных пород, которая учитывает скорость подвигания очистного забоя. В отличие от существующей методики для определения влияния подземных разработок на земной поверхности не применяются угловые параметры, а характер распределения прогнозируемых величин изменяется с увеличением глубины подработки. Предложенная методика позволяет повысить надежность прогнозирования в 3 раза. Методика прогнозирования горизонтальных сдвижений и деформаций массива горных пород для условий Западного Донбасса предложена впервые.
The thesis is devoted to the study and the establishment of complex patterns of surface and the solid of slightly metamorphosed rock mass deformation when developing gently sloping coal seams. It is established that the distribution of horizontal displacement and deformation depends on the depth of underworking, the direction of the working face movement, the stage of development of rheological processes and geometric parameters of zones of subsidence above the working face. Formation of the horizontal and vertical components of the displacement vector is influenced by various factors, which prevents the use of general principles of forecasting them. The mechanism of formation of horizontal displacement and deformation of undermined solid and geometric parameters of subsidence zones above moving working face is proposed. Method of prediction of displacement and deformation of the earth's surface and the rock mass, method of determining growth value of rock pressure at arbitrary points of high rock pressure zones are developed.

This thesis draws on David Harvey’s concept of “accumulation by dispossession” and an international political economy (IPE) approach centred on the institutional arrangements and power structures that privilege certain actors and values, in order to critique current capitalist practices of primitive accumulation by the global corporate extractive industry. The thesis examines how accumulation by dispossession by the global extractive industry is facilitated by the “free entry” or “free mining” principle. It does so by focusing on Canada as a leader in the global extractive industry and the spread of this country’s mining laws to other countries – in other words, the transnationalisation of norms in the global extractive industry – so as to maintain a consistent and familiar operating environment for Canadian extractive companies. The transnationalisation of norms is further promoted by key international institutions such as the World Bank, which is also the world’s largest development lender and also plays a key role in shaping the regulations that govern natural resource extraction. The thesis briefly investigates some Canadian examples of resource extraction projects, in order to demonstrate the weaknesses of Canadian mining laws, particularly the lack of protection of landowners’ rights under the free entry system and the subsequent need for “free, prior and informed consent” (FPIC). The thesis also considers some of the challenges to the adoption and implementation of the right to FPIC. These challenges include embedded institutional structures like the free entry mining system, international political economy (IPE) as shaped by international institutions and powerful corporations, as well as concerns regarding ‘local’ power structures or the legitimacy of representatives of communities affected by extractive projects. The thesis concludes that in order for Canada to be truly recognized as a leader in the global extractive industry, it must establish legal norms domestically to ensure that Canadian mining companies and residents can be held accountable when there is evidence of environmental and/or human rights violations associated with the activities of Canadian mining companies abroad. The thesis also concludes that Canada needs to address underlying structural issues such as the free entry mining system and implement FPIC, in order to curb “accumulation by dispossession” by the extractive industry, both domestically and abroad.

Produce a set of molds need to about 30 days, but life cycle of the product becomes shorter and shorter, the manufacturing schedule was also shortened. This research expect to use numerical simulation program to find the mold production situation when the mold design was completed, it can save the try and error. This research used thermo-solid coupling because the heat effect is large. Form the analysis results, clamping force has a large effect on the plate, and the effect on the core is injection pressure and temperature. We add the gasket to improve the slide displacement, and we find add 10μm of gasket can improve about 0.1μm. We also found change the material parameters is a large impact on the analysis. It can be observed that some parts have stress concentration problems, it may cause the product failure because the part and part can not contact tight. If the problem can be found when we design the mold, it can save the time to fix.

In this study, novel nanostructures of metal copper are discovered, including dendritic shape, wire shape and ribbon shape. Those were fabricated using galvanic displacement reaction on aluminum grid. We found that cetyltrimethylammonium chloride (CTAC) played an important role to affect the morphology of the products. If CTAC is absent in the reaction solution, copper nanodendrites were produced in the spontaneous Al-Cu2+ redox process. When CTAC was used as the growth control agent in the reaction, crystalline Cu nanowires with diameter of 30-50 nm and length up to 1 μm were grown on the substrate surfaces. Each nanowire exhibited crystallinity with [100] orientation. Further adding HNO3 into the reaction solution, large amount of ribbon-like nanobelts were made. Each nanobelt has a uniform width along its entire length, and typical widths of the nanobelts are in the range of 30-100 nm. The TEM image and diffraction patterns indicate that nanosheet structure of Cu was formed by fast growth along [100], whereas growth along [001] is suppressed, resulting in the formation of a thin sheet type of structure. Because Cu is a conductance and nanobelt structures have the high surface area, we hope their potential use as interconnects in the future nanoelectronics and application for nanosensors.

As interconnect features size shrink down to deep sub-micron region, and the overall chip speed would be limited mainly to the on-chip interconnect RC delay, not to that of device gate RC delay, and copper interconnect have been recognized as the promising mainstream for its application on high performance, and reliability for ultra-large scale integration (ULSI) semiconductor manufacturing. The current main-stream of copper metallization method is carried out by blanket Cu electroplating deposition capable of gap-filling into high-aspect-ratio vias and trenches, and implement of multi-step Cu chemical mechanical polishing (CMP) to remove the overburden Cu and TaN barrier outside of features, known as the Damascene or metal-inlaid process. The multi-step Cu CMP to precisely remove copper and tantalum or titanium nitride barrier outside the trenches without Cu over-polish would be difficult owing to the unequal removal selectivity. On the other hand, regarding the increasing aspect ratio of wires and vias, conventional physical vapor deposition (PVD) Cu seeding for the following Cu electroplating would face the step-coverage limit beyond 0.10 μm tech-node due to the poor sidewall and bottom corners coverage or overhanging on the top corners. Although the chemical vapor deposition (CVD) or electroless Cu seeding could benefit from excellent step coverage, but Cu seed formed by CVD method would suffer from the carbon or nitrogen impurities decomposed from of the metallic-organic precursors and rough surface In our study, we proposed a novel selective Cu metallization process by electrochemical contact displacement, instead of the troublesome Cu seeding and electroplating, and the complicated multi-step CMP process. Implement of the intrinsically selective Cu contact displacement from amorphous Si and the relative simple Si CMP to remove the overburden Si outside of the trenches, the selective Cu metallization can be carried out. The quality of deposited Cu film, like the electrical resistance, crystal grain orientation, adhesion to the underlying Ta barrier layer, would be evaluated by means of sheet resistance, X-ray diffraction, and stud pull testing. In addition, a novel selective galvanic deposition of Cu seed directly on the Ta barrier is also evaluated in this work. It would benefit from not only the good gap-filling capability but also the intrinsic selective deposition on the Ta barrier. In order to selectively forming Cu seed within the trenches, Ta barrier outside of trenches would be removed by CMP. After Cu seed formation, electroless plating using alkaline formaldehyde chemistry could be carried out to selectively depositing Cu into trenches. By means of this approach, both of the step-coverage issues of Cu seeding and complicated multi-step Cu CMP could be overcome.

In the construction of oil and gas well, improper displacement work (primary cementing job) may cause poor zonal isolation, cement channeling, remedial squeeze cementing, and thus lead to a severe problem. The leakage of the wellbore fluids and contamination of sensitive zones resulting from poor primary cementing job such as the Gulf of Mexico's oil spill in April 2010 has been the biggest disaster accidents for mankind history since then. The experimental flow system was developed for systematic study of both single-fluid flow and two-fluid displacement in eccentric annuli. This flow is relevant to the drilling operation and cementing operation in oil well completions, where drilling fluids are displaced from the annulus between the casing and the well bore by a series of spacer/wash fluids and cement slurries. The design of the system is based on the helical flow geometry, which is a combination of annular axial flow and tangential rotating flow in an annulus. The annular flow apparatus can be operated at various degrees of eccentricity and different angles of inclination to simulate the type of flows in oilfield drilling and cementing operations. A special feature of the flow system is that the inner pipe can be rotated during displacement, allowing the effect of casing rotation on the performance of the annular displacement process to be studied. Single fluid flow with various models of rheological fluids and displacement tests with various models of rheological fluids, especially viscoplastic fluids representing drilling and cementing fluids was conducted at different eccentricities, pipe inclinations, and over a range of flow rates and cylinder rotational speeds. Regarding the entire results of the displacement experiments, to our knowledge, the images of the moving fluid-fluid interface in annular displacement flow, especially with a rotating cylinder, generated in this work may be considered to be the world leading, since such visual information is not available in the open literature. In addition to flow visualization, the velocity of moving fluidvi-fluid interface in annular displacement flow was studied by measuring the conductivity of tested fluids. The result reveals the dynamics of displacement flow in annuli. A method was developed for simultaneously determining the displacement efficiency by measuring the conductivity of the mixed fluid phase exiting the annulus. The results obtained are of sufficient accuracy to be useful for assessing the effects of key variables such as pipe standoff, pump rate, pipe rotation and fluid rheology, on the effectiveness of annular displacement process. The relationship between the pressure gradient and the displacement efficiency has been established for the displacement process. The basic general mixing rule of a binary system occupied in term of pressure gradient may be illustrated. The pressure gradient of the mixture at any specific time of the displacement process may be illustrated by the equation comprising of the pressure gradient of each pure component in the mixture (in mass, mole, or volume fraction) derived from the results of the single-fluid flow experiments. Finally, the graph plots of the model prediction for the friction pressure gradient of the displacement process were shown, illustrating that the results from model equation collapses properly on the experimental result. To summarize, the results obtained in this work is useful for assessing the effects of fundamental variables such as eccentricity, pipe inclination, flow rate, pipe rotation and fluid rheology, that impact on the effectiveness of the annular displacement process. In particular, the flow visualization data, the velocity of moving fluid-fluid interface, the displacement efficiency, and friction pressure modelling results obtained from this project can be used to compare with, and validate, Halliburton’s 3-D simulation CFD, implemented.

The fabrication of interconnect has become an essential part of IC industry in recent years. In order to improve the function and efficiency of a chip, the dimension of interconnect must be shrunk to deep submicron. Copper is regarded as the best conducting material for interconnect in the next generation by virtue of its lower resistivity, higher melting point, and better electromigration endurance. Moreover, some drawbacks in the application of copper have already been overcome, e.g., the development of barrier layer material which solves the problem of thermal diffusion between copper and silicon oxide. Before the electrodeposition of copper, a diffusion barrier layer and copper seed layer must be deposited on top of the silicon wafer by PVD or CVD process. Titanium nitride and tantalum nitride are majorly used as the material for barrier layer in order to prevent the whole structure from thermal diffusion. Besides, seed layer was used to conduct electricity in electrodeposition process. It was found that nitride barrier material could react with some metal ions by contact displacement and deposit metal upon silicon substrate. The research of contact displacement reaction is therefore useful for evaluating the reliabilty of titanium nitride and tantalum nitride as barrier layer. Additionally, if copper can be deposited directly through this reaction or other electrochemical methods without seed layer, the cost of vaccum facilities accompanied with PVD or CVD process can be saved. The following table shows the results of different solutions in contact with various substrates. Solution SiTiN film TiN powder TaN film Ti F- / Cu2+ ○ ○ × × ○ F- / Ag+ ○ ○ ○ × ○ F- / Pd2+ ○ ○ ○ ○ ○ BHF ※ × × × ※ Cu2+ × × × × ○ Ag+ × × × × ○ Pd2+ × × × × ○ Time: 15 minutes. Temp: 20℃. Symbol ○ represents that the deposition of metal was observed. Symbol ×represents that no reaction was observed. Symbol ※ represents that the corrosion of substrate was observed. It can be seen that TiN film can react with Cu2+, Ag+, and Pd2+ in the presence of fluoride ion, while TaN film reacts with Pd2+ and F- only. Further more, metal deposition on silicon sample also takes place only when the fluoride ion exists. Thus, we concluded that fluoride ion should play an essential role in displacement reaction in all cases, which is not a simple redox reaction like the Mz+-Ti couple. In addition, the details of contact displacement reaction can be studied with the aid of some instruments, such as XRD, ESCA, SEM, and IR Spectroscopy. Three possible mechanisms of TiN displacement reaction were proposed in this study based on the results of experiments. Besides, KI and NaI were found to activate the palladium displacement without corrosion on TiN, which is superior to BHF if Pd is applied to serve as seed layer for subsequent copper deposition. Furthermore, palladium deposition atop TaN by contact displacement was found to serve as a platform or seed layer for subsequent copper electrodeposition.

Resistance spot welding (RSW) is extensively used for sheet metal joining of body-in-white (BIW) structure in the automobile industry. Key parameters, such as welding current, electrode force and welding time, are involved in the RSW process. Appropriate welding parameters are vital for producing good welds; otherwise, undersized weld and expulsion are likely to be caused. For a specific type of sheet metal, an acceptable nugget is produced when an appropriate combination of welding parameters is used. However, undersized welds and expulsion are still commonly seen in the plant environment, where some abnormal process conditions could account for the production of the poor quality welds. Understanding the influence of abnormal process conditions on spot weld quality and other RSW related issues is crucial. A range of online signals, strongly related to the nugget development history, have attracted keen interest from the research community. Recent monitoring systems established the applied dynamic resistance (DR) signal, and good prediction of nugget diameter was made based on signal values. However, the DR curves with abnormal process conditions did not agree well with those under normal condition, making them less useful in detecting abnormal process conditions. More importantly, none of the existing monitoring systems have taken these abnormal process conditions into account. In addition, electrode degradation is one of the most important issues in the plant environment. Two major electrode degradation mechanisms, softening and intermetallic compound (IMC) formation, are strongly related to the characteristics of welding parameters and sheet metals. Electrode misalignment creates a very distinct temperature history of the electrode tip face, and is believed to affect the electrode degradation mechanism. Though previous studies have shown that electrode misalignment can shorten electrode life, the detailed mechanism is still not understood. In this study, an online-monitoring system based on DR curve was first established via a random forest (RF) model. The samples included individual welds on the tensile shear test sample and welds on the same sheet, considering the airgap and shunting effect. It was found that the RF model achieved a high classification accuracy between good and poor welds. However, the DR signals were affected by the shunting distance, and they displayed opposite trends against individual welds made without any shunting effect. Furthermore, a suitable online signal, electrode displacement (ED), was proposed for monitoring abnormal process conditions such as shunting, air gap and close edged welds. Related to the thermal expansion of sheet metal, ED showed good consistency of profile features and actual nugget diameters between abnormal and normal welds. Next, the influence of electrode misalignment on electrode degradation of galvannealed steel was qualitatively and quantitatively investigated. A much-reduced electrode life was found under the angular misalignment of 5°. Pitting and electrode softening were accelerated on the misaligned electrodes. δ Fe-Zn phase from the galvannealed layer that extends electrodes was found non-uniformly distributed on the worn electrode. Furthermore, electron backscatter diffraction (EBSD) analysis was implemented on the worn electrode, showing marked reduction in grain diameter and aspect ratio. The grain deformation capacity was estimated by the distribution of the Taylor factor, where the portion of <111> pore grain was substantially weakened in the recrystallized region compared to the base metal region.

The rheology of the Earth’s lithosphere is one of the important factors in causing time dependent deformation and stress variations following the large earthquake. For the analysis of tectonics beneath Taiwan, there is evidence to suggest that the lower crust underneath Taiwan display a ductile behavior. If so, then the ductile behavior of the lower crust must be involved in studies of postseismic deformations, transfer of stress and earthquake triggering. So far, this situation was never explored in this area. Consideration of models with viscous flow in the lower crust will help improve the understanding of information about the mechanics of controlling the time-dependent process and will be needed in order to accurately decipher this problem. The crust around the rupture zone of the 1999 Chi-Chi earthquake has tangible broad-scale postseismic deformations with a short relaxation time. In this work, we first study the mechanism of crustal early (97 days and 15 months after quake) postseismic deformation due to dip-slip earthquake. Taking into account the fault slip model, we calculate postseismic surface displacements caused by Chi-Chi earthquake in the central Taiwan using a three-dimensional finite element method for different assumed multi-layered Earth’s models. In order to determine the mechanism for early postseismic deformation and the evolution of stress for 2-year period following the earthquake the comparison of GPS data and theoretical calculations allows us to establish reasonable regional Earth’s model and rheological parameters of lower crust and upper mantle. Concerning the comparison of model result with real field observations, including spatial distribution of GPS surface measurements and aftershocks response to time dependent stress field, we could provide a more realistic rheological Earth’s model and explain phenomena previously not understood. Moreover, pattern dynamics will be applied to detect a non-local seismicity pattern prior to large-size earthquakes in Taiwan. We attempt to evaluate seismicity pattern of the future earthquake in Taiwan employing the catalogue for 1973-2000. Based on the exploration of the possible mechanism containing both the viscoelastic response model and the afterslip model in the early postseismic deformation of 1999 Chi-Chi quake, we compare theoretical surface displacements for each of the two models that we evaluate. The results reveal that there is little double, that while neither of these models alone are able to predict the GPS measurements well in a 97-day period, the combination of the two models improve the predictions considerably. We conclude that the afterslip mainly dominated Chi-Chi postseismic deformation in the rupture area, while the viscoelastic model did so elsewhere. Further consideration of tectonic loading in conjuction with postseismic deformation within the central Taiwan suggests that this effect may be negligible after 97 days, but it is significant for the long-term effect that we examined with 15-month GPS data. Combined with a Coulomb failure criterion we seek to validate our calculations of the static coseismic stress changes and time-dependent postseismic stress changes by comparing them to the observed seismicity rate changes associated with the Chi-Chi earthquake. In these calculations, we have considered the effect of a regional compressional stress field whose maximum principal axis is horizontal and oriented N119°E. The results show that static coseismic stress changes explain the apparent triggering of aftershocks by mainshock, especially those that occurred in the upper crust after the first several Maxwell times of the mainshock. The relaxation of the stress in the lower part of the crust can transfer stress up to the upper crust with a roughly steady rate. This means that the viscoelastic relaxation may be responsible for the triggering of aftershocks in the upper part (10 km) of crust in the long term. Finally, we investigate the non-local seismicity patterns in Taiwan by pattern dynamics. Most of the larger-size earthquakes occurred in areas of probability increase, yielding evidence for space-time patterns of seismic activity which reflect the existence of correlations in underlying stress or strain field.

Pavel Ondrejček, Ph.D. Student: Tomáš Marcinek Title of Thesis: The influence of the tableting speed on the compaction process The main aim of this thesis was to determine the influence of tableting speed on the compaction process of four substances. The compaction process was evaluated by three- exponential equation. The parameters of this equation describe the individual phases of compression, the precompression phase, the phase of elastic deformation and the phase of plastic deformation. Furthermore, the effect of tableting speed on the compressibility of the material was studied using the force-displacement record. Finally, the influence of tableting speed on tensile strength of the prepared tablets was evaluated. Four materials were used for the evaluation. Microcrystalline cellulose Avicel PH-102 and dicalcium phosphate dihydrate DI-CAFOS were used as model fillers. Theophylline and paracetamol were used as model drugs. The course of the compaction process was evaluated at five compaction speeds. The results of this evaluation revealed different behavior of used materials. Furthermore different influence on the compaction process by changing compaction speed was...

That was evaluated by parameters of three-exponential equation. Compressibility was studied by using force-displacement record. In this work was also observed an effect of die size on the tensile strength. In processing the experimental part of this work were used four different model materials.

Compaction of these materials was carried out in dies of size 7 mm, 9 mm, 11 mm, 13 mm and 15 mm. The results of the work showed that the die size significantly affects all parameters force-displacement record. With the growing size of the die there was a reduction of energy parameters. Most of the compaction parameters were statistically influenced.

Pavel Ondrejček, Ph.D. Student: Žofie Trpělková Title: A study of a compaction process of microcrystalline cellulose pellets This work is aimed at the comparison of two types of microcrystalline cellulose (Comprecel 102 a Avicel PH-200) with two types of pellets made of microcrystalline cellulose (Cellets 100 a Cellets 200). Important properties for the compaction into tablets were analyzed in these materials. The particle size distribution, the content of moisture, the bulk and tapped density, the flowability, the angle of repose and the Hausner ratio were evaluated. Furthermore, the compaction process was described by using the force displacement method and the three-exponential equation. Finally, the radial strength and the friability of tablets prepared by using two different compaction forces were evaluated. The results proved that both types of pellets have much better flow properties than powdered microcrystalline celluloses. This is primarily caused by the narrow particle size distribution, higher bulk and tapped density and the significantly smoother surface of pellets. Better flow properties of the pellets also influenced the parameters of the force-displacement...

Se plasma el análisis en pautas, para ser utilizado en modo genérico, dentro de un servicio de monitoreo operativo de procesos de remoción en masa.
This work describes the basic guidelines in order to study landslides using remote sensing. There are presented three test cases in different scenarios: The first one in South Tyrol (Northern Italy), the second one in El Hierro Island (Canary Islands, Spain), and the last one in Sierras Chicas (Córdoba, Argentina). Implemented techniques were: a) Photointerpretation, b) Interferometry between pairs to generate displacement maps and c) Multitemporal interferometry (Persistent Scatterer – PS) to analyze displacements in temporal series of SAR images. Results include a) inventory vector layers to be obtained from a photo-interpretation, i.e. process recognition and type of rock; b) requirements on both, data to be used in an interferometric analysis and on the characteristics of the area of interest which could affect the resulting displacement. From each studied case, learnt lesson were used to generate the guidelines to extract information to study a generic landslide case using remote sensing. The above generic approach was used to generate several guidelines to be used in a landslide operative monitoring service.
