It is well known that feedback is a very valuable tool for analog designers to improve linearity, and desensitize various parameters affected by process, temperature and supply variations. However, using strong global feedback limits the operation speed of analog circuits due to stability requirements. The circuits and techniques explored in this research avoid the usage of strong-global-feedback circuits to achieve high conversion rates in a two-stage analog-to-digital converter (ADC). A two-step, 9-bit, complementary-metal-oxide-semiconductor (CMOS) ADC utilizing an open-loop residue-amplifier is demonstrated. A background-calibration technique was proposed to generate the reference voltage to be used in the second stage of the ADC. This technique alleviates the gain variation in the residue amplifier, and allows an open-loop residue amplifier topology. Even though the proposed calibration idea can be extended to multistage topologies, this design was limited to two stages. Further, the ADC exploits a high-performance double-switching frontend sample-and-hold amplifier (SHA). The proposed double-switching SHA architecture results in exceptional hold-mode isolation. Therefore, the SHA maintains the desired linearity performance over the entire Nyquist bandwidth.

This master’s thesis deals with design of measurement system for dynamic measurement of bridge sensors. After a short theoretical part, the own concept is introduced. System can provide sampling rate up to 250 kSa/s with 24-bit resolution. The maximum number of samples is about one and a half milion. At first, the design of analog part was made, in this phase of design the digital part is based on evaluation board with ARM Cortex-M7 and external memory. After final choice of appropriate ICs, the analog and digital part will be integrated into one PCB.

在這篇文章中，我們由單擺運動的觀念得出深層地震持續時間的估計，以及討論了關於地震方程的良至性與週期性，並且得出關於持續時間的表現公式。最後，利用台北中央氣象局關於地震記錄的數據，來驗證我們以上的結果。 / In this paper, we obtain the duration of deep earthquakes coming from the concept of pendulum motion. We consider the well-posedness and periodicity of the solutions for the seismic equation and get representation formula of duration for the equation. We revise the validity of our work by using numerical data gained from Center Weather Bureau in Taipei, Taiwan.

Este trabalho investiga a formação, na segunda metade da década de 1990, daquilo que alguns grupos ativistas denominaram anticapitalismo global. A pesquisa buscou acompanhar a emergência dessa nova forma de ativismo por meio da reconstituição do processo de construção da rede mundial de luta contra a globalização neoliberal que começou a se formar em solidariedade ao levante do Exército Zapatista de Libertação Nacional (EZLN) no México, em janeiro de 1994, ganhou corpo com a realização do Primeiro e do Segundo Encontros Intercontinentais pela Humanidade e contra o Neoliberalismo, em 1996 e 1997, respectivamente, e culminou na fundação, em 1998, da Ação Global dos Povos (AGP), rede de movimentos sociais que criou os dias de ação global e inspirou as grandes manifestações contra as reuniões de instituições multilaterais como a Organização Mundial do Comércio (OMC), o Fundo Monetário Internacional (FMI) e o Banco Mundial a partir do protesto que impediu a realização da abertura da terceira Conferência Ministerial da OMC em Seattle, em novembro de 1999. O objetivo deste trabalho é analisar o processo de emergência e descrever as características centrais de um novo tipo de anticapitalismo que surgiu a partir da articulação das lutas contra a globalização neoliberal em nível mundial e situá-lo na longa tradição das lutas anticapitalistas dos séculos XIX e XX, mostrando como as transformações do modo de produção capitalista deram origem a novas formas de resistência ao longo desse período. Para isso, conduzi uma pesquisa em dois planos, um teórico e outro empírico. A pesquisa empírica se baseou no levantamento e análise de documentos produzidos pelos movimentos que integraram a rede mundial de luta contra a globalização neoliberal entre 1994 e 1998. A pesquisa teórica consistiu na aplicação de um modelo teórico elaborado a partir da combinação de duas leituras contemporâneas da economia política marxiana para analisar as transformações do capitalismo e do anticapitalismo ao longo dos séculos XIX e XX. Esse modelo foi elaborado a partir da teoria do antagonismo de classe formulada pelos pensadores operaístas e autonomistas italianos, como Antonio Negri e Mario Tronti, e da teoria dos ajustes espaçotemporais via acumulação por espoliação de David Harvey. Ao aplicar esse modelo teórico à análise dos dados empíricos fornecidos pelas fontes textuais produzidas pelos movimentos que formaram a rede mundial de luta contra a globalização neoliberal foi possível constatar a emergência de um novo anticapitalismo que surgiu em resposta às transformações do modo de produção capitalista a partir da crise de acumulação iniciada na década de 1970 e que deu origem a uma nova estratégia de enfrentamento do capital e a uma nova concepção do sujeito revolucionário. Como a pesquisa se baseou nas declarações escritas dos movimentos envolvidos na construção da rede mundial de luta contra a globalização neoliberal, os resultados obtidos permitem falar em um novo discurso anticapitalista, mas não fornecem os elementos necessários para atestar a emergência de uma nova prática anticapitalista capaz de se enraizar no cotidiano dos movimentos envolvidos. Por isso, o trabalho conclui sugerindo que é necessário realizar pesquisas de história oral para verificar se e como esse discurso se refletiu na prática cotidiana dos movimentos integrantes da rede. / This work investigates the formation, in the second half of the 1990s, of what some activist groups have called global anticapitalism. The research analyzed the emergence of this new form of activism by studying the building of the worldwide network of struggle against neoliberal globalization that began to take shape in solidarity to the uprising of the Zapatista Army of National Liberation (EZLN) in Mexico, in January 1994, strengthened itself with the organization of the First and Second Intercontinental Encounters for Humanity and Against Neoliberalism, in 1996 and 1997, and culminated in the foundation, in 1998, of Peoples Global Action (PGA), a netowrk of social movements that created the global days of action and inspired the big demonstrations against multilateral institutions such as the World Trade Organization (WTO), the International Monetary Fund (IMF) and the World Bank, starting with the protests that shut down the inaugurarion of the third Ministerial Conference of the WTO in Seattle, in November 1999. The aim of this work is to analyze the emergence and describe the main characteristics of a new kind of anticapitalism that grew out of the articulation of the struggles against neoliberal globalization in a global level and situate it within the long tradition of anticapitalist struggles of the 19th and 20th centuries, showing how the transformations of the capitalist mode of production gave birth to new forms of resistance. To do that, I have conducted a research in two levels, one theoretical and the other empirical. The empirical research was based on the analysis of documents produced by the movements that formed the worldwide network of struggle against neoliberal globalization between 1994 and 1998. The theoretical research consisted in the application of a theoretical model built upon the combination of two contemporary interpretations of the Marxian political economy in order to analyze the transformations of both capitalism and anticapitalism through the 19th and 20th centuries. This model was elaborated departing from the theory of class antagonism formulated by Italian workerist and autonomist intellectuals such as Antonio Negri and Mario Tronti, and from David Harveys theory of spatiotemporal fixes through accumulation by dispossession. By applying this theoretical model to the analysis of the empirical data provided by the textual sources produced by the movements that formed the worldwide network of struggle against neoliberal globalization it was possible to see the emergence of a new anticapitalism that took shape in response to the transformations of the capitalist mode of production since the accumulation crisis started in the 1970s and that gave rise to a new strategy to confront capital and to a new conception of the revolutionary subject. Since the research was based on the written declarations of the movements that built the worldwide network of struggle against neoliberal globalization, the results allow us to identify a new anticapitalist discourse, but dont provide enough elements to prove the emergence of new anticapitalist practices rooted in the everyday life of the movements involved in the network. Thus, the work concludes suggesting the necessity of conducting oral history researches to verify if and how this discourse was reflected in the everyday practice of the movements that took part in the network.

Ce travail de thèse a pour objectif de développer une méthodologie permettant de prédire l’impact environnemental des futurs projets miniers, dès l’étape d’exploration. Le drainage minier acide, connu comme le principal problème environnemental des gisements sulfurés, se produit lors de l’oxydation des sulfures par l’oxygène et l’eau. Des échantillons de sulfures et sulfosels ont été soumis à des tests géochimiques afin d’étudier leur taux de réactivité. Les minéraux ont été classés par ordre décroissant: gersdorffite > pyrrhotite > arsénopyrite > Ni-pyrite > Ni-pyrrhotite > Fe-sphalérite > pyrite > galène > chalcopyrite. L’influence des interactions galvaniques sur le taux de réactivité de la pyrite, la chalcopyrite et la sphalérite a été étudiée. La pyrite est protégée galvaniquement en présence de chalcopyrite mais n’est pas complètement protégée en présence de sphalérite. Des mélanges synthétiques de minéraux purs ont permis la modification du calcul de potentiel de génération d’acidité par l’ajout d’un facteur cinétique, basée sur les équations de Paktunc (1999) et Bouzahzah et al. (2013). Dix minerais polymétalliques et aurifères ont été caractérisés selon une méthodologie pluridisciplinaire. La caractérisation minéralogique des minerais a permis de connaître leur composition minéralogique quantitative et de détecter les éléments contaminants ainsi que leur spéciation. Une méthode automatisée de quantification minéralogique basée sur la microscopie optique multispectrale a été développée. Cette innovation vise à développer la microscopie optique pour des applications métallurgiques et environnementales de routine / This thesis proposes the implementation of a reliable methodology, based on the characterization of ores at the exploration stage. The main environmental issues for the mining industry are acid mine drainage and contaminated neutral drainage. Sulfides and sulfosalts, when in contact with water and oxygen, oxidize at different rates, resulting in the production of acid and release of various contaminants. Samples of pure sulfides were submitted to geochemical testing to determine their oxidation rates. The pure minerals can be ordered from the highest to the lowest reactivity as: gersdorffite > pyrrhotite > arsenopyrite > Ni-pyrite > Ni-pyrrhotite > Fe-sphalerite > pyrite > galena > chalcopyrite. Galvanic interactions between pyrite, chalcopyrite, and sphalerite were geochemically investigated. Pyrite was galvanically protected in presence of chalcopyrite, and partially protected in presence of sphalerite. Five synthetic tailings, simulating realistic tailings sulfides compositions, were prepared to compare geochemical behaviors and produce a better assessment of the acid-generation potential (AP). A new method is proposed by adding a kinetic factor. Ten polymetallic and gold sulfide ores were fully characterized with multidisciplinary techniques. Mineralogical investigations allowed for the mineralogical quantification of the ores, and for the knowledge of trace elements and their speciation. A method was developed to automatically quantify sulfides by multispectral optical microscopy. Detailed mineralogical work can save time and money and allows detecting the problems at the beginning of mining developments, improving mine waste management and mine closure planning

BARAPROJEKTET: Av författarna formulerat samlingsnamn för Professional Golfers´ Association (PGA) National Sweden AB:s köp av aktuella fastigheter från Malmö kommun och planprocessen i Svedala kommuns regi.Syftet med denna rapport är att undersöka alternativ till, det av Malmö kommun valda förfarandet, att försälja fastigheten Värby 61:1 med flera till PGA: s golfbaneprojekt i Svedala kommun samt få kunskap om den planprocess som föregick beslutet.I vårt val av metod har vi varit angelägna om att skapa förutsättningar för replikation och utvärdering. Rapport är utförd med en kvalitativ fältstudie med ett strategiskt urval, kompletterat med en sekundär analys. Undersökningen bygger på en explorativ metod genom att vi kompletterat våra sekundärdata med ett flertal intervjuer. Genom vår omfattande granskning bedömer vi att rapporten har en god reliabilitet samt att vi fått tag i de intervjupersoner som kan tillföra rapporten god validitet.1996 initierade Mikael Sorling, vd PGA Sweden AB visionen om att anlägga en golfanläggning av högsta internationella klass i Sverige. 2003 började Nils Yngvesson, före detta kommunalråd i Malmö kommun, arbeta med golfanläggningen och det var han som lade fram iden om att golfanläggningen skulle ligga i Torup. Marken som golfanläggningen skall anläggas på ägdes sedan 1970 av Malmö kommun, medan marken ligger i Svedala kommun. Sedan Malmö kommuns förvärv av marken 1970 har Torups Gård AB arrenderat marken för jordbruk.Slutsatsen i denna rapport är att PGA National Sweden AB köpt jordbruksmark till ett rimligt pris sett i relation till marknadsvärdet. Dock så vet vi att jordbruksmarken inte skall fortsätta att brukas, utan jordbruksmarken skall istället användas för anläggandet av deras nya golfanläggning. Marknadsvärdet för golfbanemark ligger nästan dubbelt så högt per hektar än vad PGA National Sweden AB köpte jordbruksmarken av Malmö kommun för. I Malmö kommuns värdering av jordbruksfastigheterna har de inte tagit hänsyn till objektsbundna värdepåverkande faktorer. Vi menar att sådana föreligger, dock så är de svåra att värdera. Konsekvensen av detta blir att priset på jordbruksfastigheterna borde vara väsentligt högre.Den aktuella planprocessen för Baraprojektet har effektivt följt det normala planförfarandet. Orsaken är att de berörda aktörerna tidigt kom överens. N Yngvessons inträde i PGA National Sweden AB:s styrelse samt parternas kompetens och personkemi har även de varit en bidragande faktor till att arbetet med planprocessen förflutit effektivt.Den nyttjanderättsform som parterna kunde ha använt sig av, snarare än att försälja de aktuella jordbruksfastigheterna, är tomträtt. Valet av tomträtt bygger på att Malmö kommun kvarstår som fastighetsägare och behåller då sin handlingsfrihet. Under den första 10-års perioden kunde ett generöst tomträttsavtal ingås mellan parterna, därmed skulle goda förutsättningar för golfanläggningens etablering säkerställas. / Our aim is to investigate alternatives to the sale of the properties Värby 61:1 etc. by Malmö municipality to PGA:s golf course project in Svedala municipality and to understand the planning process that preceded the decision.Our investigation is based on an explorative method where we complemented our secondary data with a number of interviews. Through our extensive observation we estimate that the rapport has good reliability and that we have accessed the right people who are able to add good validity to the rapport.Malmö municipality has not taken in consideration the unique object value factors when selling the property. Our opinion is that these factors do exist, although they are difficult to estimate. The result of this is that the price of the land should be much higher. Nils Yngvesson joining PGA National Sweden’s board’ and the parties’ competence and personal chemistry have also been a contributing factor to why the work with the normal planning process has been carried out so efficiently. The right of use that could be utilized by the parties instead of selling the land would be a leasehold right. In our opinion this would have benefited both parties with concerns regarding risk and value.
