A novel offset voltage compensation method is presented that significantly modifies the existing tradeoff between control loop bandwidth, and therefore total compensation time, and total output jitter. The proposed system achieves comparable output jitter performance to traditional approaches while significantly reducing the total compensation time by nearly three orders of magnitude. Traditional offset compensation methods are based on simple offset measurement techniques that generally rely on passive compensation blocks and exhibit a direct inverse relationship between total compensation time and resulting output jitter. Therefore, current high-speed data-link systems suffer from extremely long offset compensation loop settling times in order to satisfy the strict protocol jitter specifications. In the proposed system, the new CMOS peak detector design is the enabling component that allows us break this relationship and achieve extremely fast settling behavior while preventing data dependence of the control signal. Simulated results show that the implemented system can achieve output jitter performance similar to existing methods while dramatically improving the compensation time. Specifically, the proposed system can achieve less than 2pS of peak-to-peak jitter, or less than 700fS of RMS jitter, while reducing the total compensation time from roughly 500[mu]S to less than 1[mu]S. The system was implemented in National Semiconductor's CMOS9 0.18[mu]m CMOS process. Packaged parts will be tested to verify agreement with simulated performance.

Повний текст джерелаIn response to the increasing loss of biodiversity, several countries have adopted offsetting policies that seek to balance local habitat destruction by restoring, enhancing and/or protecting equivalent values offsite. Such mechanisms are increasingly important in quarrying, where habitat loss may be unavoidable due to colocation of mineral resources and areas of biodiversity importance. Seeking to contribute to advance understanding of the current practice of biodiversity offsetting, we investigated actions required for environmental approval of three limestone quarries in compliance with Brazil\'s Atlantic Forest Act, a federal law that aims at protecting this biodiversity hotspot. Both protection and restoration offsets were applied at area ratios from 1:1.1 to 1:5. The main difficulties reported by practitioners are to find suitable areas, methods to calculate residual losses and uncertainties about the success of restoration. Internationally recommended best practices are partially followed with the highest adherence observed for the case whose environmental impact statement was more detailed and provided a stronger basis for designing the offset. Results suggest that the quality of offset planning and implementation is directly related to the quality of the environmental impact assessment.

Повний текст джерелаOffsets arrangements in government procurement are discriminatory policy tools aimed at increasing local production. They reflect a transfer or a creation of new activities as a pre-condition to the validity of the purchasing contract. The governments use these mechanisms to encourage local development or to improve the balance-of-payments. In spite of the broad utilization of offset practices, they are relatively unknown and little described in academic literature. The goal of this thesis is to define, to explain and to assess the importance of these practices in the international trade and to provide a theoretical framework within which it will be possible to critically appraise the success of an offset policy (its effectiveness and efficiency) for host countries. In order to take into account the success factors for an offset policy, the relationship between the host country and the obligor as well as the result of this relationship is examined through the game theory approach. By applying this general framework to the study of South African Offset policy and more particularly to the evaluation of 121 civil offset projects provided between 1996 and 2012, under the Strategic Defense Package purchase we find the following results: at the conclusion of public procurement contracts, South-African offset projects hold out promises of important economic benefits for the country. Nevertheless, during the implementation process, many violations of rules and procedures decrease the positive impact of these projects and hinder their effectiveness. The lack of transparency in the negotiation process, the selection and the execution phase of offset projects show that South Africa did not obtain best value for public money. It is difficult to appraise global program efficiency because of lack of data and analysis problems. However the estimated impact remains positive

Logarithmic map circuits are useful in many applications that require non-linear signal compression, such as in speech recognition and cochlear implants. A logarithmic current-mode A/D converter with temperature compensation and automatic offset calibration is presented in this paper. It employs a dual-slope, auto-zeroing topology with a 60 dB dynamic range and 300 Hz sampling rate, for capturing the envelope of speech signals in a bionic ear. Fabricated in a 1.5 [mu]m process, the circuit consumes only 1 [mu]W of analog power and another 1 [mu]W of digital power, and can therefore run for over 50 years on just a couple of AA batteries. At the current level of power consumption, we have proven that this design is thermal-noise limited to a 6-bit precision, and higher precision is possible only if we expend more power. As such, it is already useful for cochlear implants, as deaf patients can only discriminate 1 dB out of a 30 dB dynamic range in the auditory nerve bundles. For the purpose of using this circuit in other applications, we conclude with several strategies that can increase the precision without hurting the power consumption.

As preocupações com a degradação ambiental cada vez mais visível em meados do século XX mobilizaram as Conferências da Organização das Nações Unidas (ONU) sobre meio ambiente em Estocolmo (1972) e no Rio de Janeiro (1992). Esse movimento deu origem às políticas ambientais no Brasil, marcadas pelas concepções de meio ambiente da época. A Política Nacional do Meio Ambiente, de 1981, cria instrumentos para compatibilizar o desenvolvimento econômico-social com a preservação da qualidade ambiental e do equilíbrio ecológico. O controle de empreendimentos poluidores é feito por meio do licenciamento e da avaliação de impactos ambientais. Já a criação de espaços territoriais especialmente protegidos é uma ferramenta da Política para a conservação da biodiversidade. No Brasil, estes instrumentos embasam a compensação ambiental, a qual garante recursos de empreendimentos licenciados para criação e manutenção de unidades de conservação. Internacionalmente, o objetivo da compensação é alcançar a equivalência entre perdas e ganhos em termos de biodiversidade, de forma mensurável. Nesta dissertação é investigada a possibilidade da compensação ambiental no Brasil ser considerada um mecanismo gerador de ganho ambiental ou que garanta, minimamente, não haver perda de biodiversidade na implantação de projetos licenciados. Os estudos de caso evidenciaram que o procedimento de licenciamento não aponta claramente a conexão entre os impactos identificados nos estudos ambientais, e as medidas de mitigação e compensação executadas. As compensações, no entanto, revelaram que há equivalência ecológica entre a área impactada e as unidades de conservação beneficiadas. Conclui-se que a ferramenta de compensação ambiental brasileira apresenta potencial de contribuição para a perda zero de biodiversidade nos empreendimentos licenciados, sendo necessária a adequação no procedimento de licenciamento para a utilização da hierarquia de mitigação, e a exigência de medidas compensatórias que sejam mensuráveis e que garantam a equivalência ecológica entre as áreas impactadas e protegidas.
Worries about the ever more visible environmental degradation in the mid-twentieth century ignited the United Nations’ (UN) Conferences on the Environment in Stockholm (1972) and in Rio de Janeiro (1992). This movement originated environmental policies in Brazil, marked by the period’s understanding of environment. The 1981 National Environmental Policy creates instruments to reconcile social-economic development and preserving environmental quality and ecologic balance. Polluting enterprises are controlled through licensing and the environmental impact assessment. The creation of protected areas is tool in the policy for biodiversity conservation. In Brazil, these instruments are the foundation of environmental compensation (offset), which guarantees resources from licensed enterprises to create and maintain conservation units. Internationally, the goal of offset is to reach the equivalency between gains and losses in terms of biodiversity in a measurable way. In this dissertation, the possibility of environmental compensation in Brazil being considered a mechanism to generate environmental gain and to guarantee, at a minimum, no loss of biodiversity in the establishment of licensed projects is investigated. Case studies show that the licensing procedure has no clear connection between impacts identified by environmental studies and executed mitigation and compensation measures. Compensations, nevertheless, reveal that there is ecologic equivalency between the impacted area and the benefited conservation units. In conclusion, Brazil’s environmental compensation tool presents the potential to contribute to zero net loss of biodiversity in licensed enterprises. However, it is necessary to adjust the licensing procedure in order to use mitigation hierarchy, and the requirement of measurable compensatory ecologic equivalency measures.

Повний текст джерелаThe aim of ecological offsets is to combine environmental protection with the social and economic opportunities of implementing new projects on natural spaces. Technically, these measures involve restoring balance between ecological damages and ecological benefits to be provided for by the ecological offset. Ecological offsets measures became mandatory in the seventies, yet their adequacy is still questioned today. They are administrative policy measures, distinct from liability. Although several different ecological offsets exist, no law explicitly defines them. It appears then very important to know whether it’s possible to draw one global legal definition of ecological offset, in order to assure the achievement of the ecological goals of all this measures: providing effective reparation of the damages caused to the ecosystems. All the more as the lack of legal offset criteria is adding to already existing practical difficulties which may in term bring about the downfall of ecological offset.Actually, though it is widely presented as a legal instrument to reverse the loss of biodiversity; reality shows that this purpose may not be attained, especially because of a lack of unanimous ecological measurement model. That’s why ecological offset deeply needs a legal characterization of what it should be. After this attempt at a definition, the thesis proposes to explore the future of the ecological offset, including the opportunities offered by shared sites of natural remediation

A presente pesquisa teve como meta avaliar criticamente em que medida os Acordos de Offset contribuem para o desenvolvimento da indústria de defesa, na perspectiva do setor aeronáutico brasileiro. Buscou-se analisar o processo de transferência de tecnologia, a partir dos acordos de compensação firmados no Projeto H-X BR, cujo objeto é a aquisição de 50 helicópteros franceses e suporte logístico inicial, destinados à satisfação de demandas operacionais das três Forças Armadas. A presente pesquisa analisou também as contribuições teóricas das principais linhas de pensamento em relação ao papel da inovação para o segmento de defesa, levando-se em conta os múltiplos participantes da estrutura estatal, a análise do arranjo normativo brasileiro e a natureza jurídica das práticas compensatórias, bem como o papel dos atores envolvidos no processo de aprovação dos Acordos de Offset.

Повний текст джерелаInvestment in low carbon infrastructure is considered an important component of the fight against climate change. The mechanisms of climate regulation (such as carbon offsets) transfer to project developers the risks associated with reducing emissions of greenhouse gas (GHG) emissions, i. E. Operational and technological risk, or risks associated with the environmental monitoring and the regulatory mechanism itself. The success of projects depends importantly on the risk sharing arrangements between the private and public partners. It is shown that the delegation of tasks between the partners can create risks that affect the environmental effectiveness and economic efficiency of the project. For a sample of landfill gas flaring projects financed under the Clean Development Mechanism, it is shown that the outsourcing of the provision of technology creates additional risks. The outsourcing of the development of the official project documentation required by the UNFCCC and the separation of the operation of the landfill and the CDM project development appear to be manageable by risk sharing arrangements

O tema do presente trabalho são os contratos de compensação, mais especificamente, aqueles que incluem transferência de tecnologia. Os contratos de offset foram analisados consoante sua instrumentalidade e procedimentalidade. O estudo teve como foco o setor de defesa brasileiro em virtude da experiência adquirida por este setor no emprego do instituto contratual das compensações. Partiu-se das seguintes indagações: de que maneira as compras públicas no setor de defesa podem contribuir com o desenvolvimento tecnológico nacional? E ainda: quais fatores impactam a efetividade das compensações tecnológicas? Realizou-se inicialmente pesquisa bibliográfica e documental. Na sequência, realizou-se pesquisa empírica, cujos instrumentos de coleta de dados utilizados foram o painel de especialistas e o questionário on-line. Identificou-se que há grande interação entre o setor de defesa e a inovação tecnológica, e que as compras públicas de defesa podem estimular o desenvolvimento tecnológico a partir de acordos de compensação tecnológica. Outrossim, os órgãos integrantes da defesa já dispõem de estrutura capaz de apoiar o desenvolvimento tecnológico nacional e balizam seus projetos e setores estratégicos por tecnologias inovadoras. No que tange às espécies compensatórias, identificou-se que os offsets tecnológicos são os que possibilitam benefícios mais expressivos para o caso brasileiro, dado o hiato tecnológico que separa o país dos Estado desenvolvidos. Dada a complexidade das compensações tecnológicas, foram identificados doze critérios para avaliação das propostas de offsets tecnológicos, divididos em noventa e seis subcritérios. A partir do processo analítico hierárquico, os critérios e subcritérios foram submetidos ao painel de especialistas. Obteve-se como resultado uma matriz de avaliação de propostas de compensações tecnológicas, a qual contém o valor percentual correspondente à contribuição de cada subcritério para a meta institucional de promover o desenvolvimento tecnológico nacional. Realizou-se estudo de caso do projeto piloto do Sistema Integrado de Monitoramento de Fronteiras (SISFRON), que é um projeto estratégico do Exército Brasileiro. A matriz de avaliação foi validada a partir da sua aplicação às propostas das compensações tecnológicas em execução no referido projeto, obtendo-se um valor numérico para cada proposta, possibilitando priorizar as propostas com base em dados objetivos. A partir das respostas ao questionário on-line, constatou-se que os fiscais dos contratos de compensação tecnológica têm baixo grau de concordância com o painel de especialistas, o que indica que o processo de avaliação de propostas de compensação tecnológica depende de um conjunto de expertises que incluem conhecimentos jurídicos, técnicos e gerenciais. Concluiu-se que as compensações tecnológicas resultantes de compras públicas em defesa podem contribuir com a política pública de inovação desde que esta seja ampla o suficiente para abarcar a defesa e outras áreas de atuação estatal.

Повний текст джерелаThis dissertation deals with the so-called “voluntary” carbon offset market. In this market, companies, which have no obligation to subscribe to these services, purchase “carbon credits” to “offset” their greenhouse gas (GHG) emissions from private operators (NGOs or businesses). To obtain carbon credits, operators implement GHG emission reduction projects in Southern countries. These new trade exchanges, which date from the early 2000s, provoke critics. Journalists, environmental NGOs and scientists believe that this market on the one hand does not effectively reduce GHG emissions to fight against climate change, and on the other hand that people in the South face potential dangers linked to the implementation of carbon offsetting projects. The dissertation thus questions the apparent paradox of the choice of companies to invest in contested environmental services when they are not a regulatory obligation and may endanger their reputation. By considering the “voluntary” market as a “contested market”, according to the meaning given to this notion by Steiner and Trespeuch (2014), the dissertation explores the conditions of existence and maintenance of this market. Through interviews, observations and written sources, our research analyzes the role of various market devices, but also commercial work as well as the appropriation of the offer by buyers in organizing this market. In doing so, it questions more generally the relationship between economy and the environment and is interested in the determinant factors of the “voluntary” commitment of companies for the fight against global warming

Повний текст джерелаThe voluntary carbon offset market is a market mechanism for offsetting greenhouse gases emissions for organizations and individuals that are not legally committed to reductions. Until now it has not been studied much in academic circles. This dissertation looks at the governance of the chain of actors involved in the mechanism. A pluri-disciplinary approach is used based on international relations, political science of offsets and standards combined with an anthropological analysis of development projects. The central question is thus: how are carbon-offset programs governed? The empirical work is a case study of a new stove (improved cookstoves) diffusion program in Peru under the Gold Standard. The first focus is on the social and cultural context of cooking in the Andes. Then four projects before carbon funding are studied. The standard is the subject of the following section and the retailer of the credits generated by the programme and three different types of clients are then presented. We can then discuss the creation, design and management of the standard through an ethnography of the social business that implements. Finally, the influence of the projects on the sector can be discussed. The chain studied presents a governance system that is multi-level and multi-actors, with mainly private actors that act parallel to the state. This type of governance is characterized by a series of standards that define the model the reality should resemble to and is called standardism

Повний текст джерелаMy research topic is multidisciplinary combining geography, ecology and economics and addressing the efficiency of current marine offset practice. Building on a state of the art of current practice, I am working on a more prospective approach (compared to current research on mitigation targeting terrestrial ecosystems). By offset, I am referring to legal mitigation that consists in avoiding – reducing – offsetting adverse impacts of development projects such as dredging, port infrastructure, oil exploration, marine aggregate extraction, beach nourishment, etc. on marine and coastal ecosystems. Based on a review of around fifty French marine Environmental Impact Assessments (EIAs), I analyzed the assessment of impacts, the use of offset sizing methods (robust method to assess ecological losses due to development projects and ecological gains created by offset measures) and the kind of measures proposed. Within these EIAs, sizing methods were seldom used and the very few measures suggested to offset residual impacts could be questioned in terms of equivalency and appropriateness. These measures were either ecological engineering techniques (such as seagrass or coral restoration), management measures (used to reduce pressure on the impacted ecosystems through the funding of management measures in Marine Protected Areas for example) or even knowledge acquisition. Thus, I am also looking at the efficiency of ecological engineering techniques on marine and coastal ecosystems. My research mainly focuses on the offset of authorized impacts but could also deals with some aspects of the offset of accidental damages

Повний текст джерелаIn the current contextof energetic transition, public policies commit to reduce fossil fuel consumption and develop renewable energies in order to reduce CO2 emission. Woody biomass can be one of the solutions in order to increase the share of renewable energu ressources in energetic mix. In order to increase woody biomass production, an export of logging residues (under 7 cm of diameter) is investigated. Furthermore, in order to offset th export of organic matter with logging residue, mineral compensation by wood ash application is investigated. Nevertheless, the effect of such management practices on temperate forest ecosystem were understudied. The aims of this thesis were to study the impact of logging residues management intensity and wood ash offset on soil biota and to investigate potential bioindicators of disturbance led by these practices. First, the study on macrofauna and mesofauna at various scales (regional then northen French) highlited the importance of tree species (oak or beech) the response of soil biota to logging residue export. Furthermore, this first part showed a strong negative impact on the whole soil community when logging residues and litter were exported and wood ash application did not compensate the impacts of logging residues export on macro and mesofauna. Second, a mesocosm study with a cross-gradient of logging residue and wood ash input highlighted the importance of mineral fertility in the response of soil-plant interface. In neutral soil, logging residue export or wood ash application did not impact soil-plant interface, conversely to acidic soil. Furthermore, in acidic soil, a strong structural disturbance of microfloral assemblage was showed when logging residue and wood ash were added together. Third, this thesis highlighted Litobiomorpha and Geophilomorpha orders as potential sources of bioindicators of disturbance of trophic networks in logging residue export and wood ash offset context of forest management practices

Повний текст джерелаIn France, since 1976, the impact assessment of development plans must include measures to avoid, minimise and, if possible, offset adverse impacts. This regulation remained unimplemented untill the 1990’s but became the norm with the Grenelle de l’environnement. Built according to the mitigation hierarchy, this regulation relies on the principle of « no net loss of biodiversity » and aims for an ecological equivalence. Several research studies on offset design already extist and concern mainly the accounting models and institutional arrangements. This thesis focuses on practices, i.e. on the work accomplished by those who make the environmental assessment, who review the offseting plan and who finally implement the offsets.This research is based on an ethnographic study of assessment and counter-assessment all along the regulatory pocess. This thesis is built on three questions : how are ecological equivalence and offset measures produced ? ; how do they both become a social reality ? ; what are the physical and conceptual conditions to implement biodiversity offsetting ? These issues aim to point out what makes this regulation possible despite it being subject to numerous contradictions and challenge.The central assumption of this thesis is that the form of the regulation (its institutional arrangements, the assessment models, the practices one can observe) results from the attempt to solve its contradictions. The main conclusion the research leads to is that biodiversity offset produces not only environmental assessments and offset measures, but also its own conditions of development, the physical and conceptual substrate on which it can exist and spread

A compatibilidade da Política de Compensação Comercial, Industrial e Tecnológica do Ministério da Defesa (offset) com o regime internacional de proteção do know-how. A importação de tecnologias de segurança e defesa dá-se ainda assim, a despeito da pretensão de autodeterminação dos países e em favor da segurança jurídica, segundo regimes internacionais e domésticos dos contratados. A compatibilidade entre as políticas de aquisição e gestão do conhecimento deve ser aferida em relação à normatização internacional e estrangeira, sob pena de insegurança jurídica e sanções internacionais. Este estudo investiga a compatibilidade da política de offset do Ministério da Defesa brasileiro com o regime internacional de proteção do know-how, na transferência internacional de tecnologia. O propósito da pesquisa é identificar possíveis incongruências, de modo a orientar políticas públicas. Parte-se, por outro lado, da hipótese que haja total congruência entre elas. O tema será abordado primariamente conforme o positivismo jurídico, com enfoque dogmático. O método de abordagem é o dedutivo. A base documental da pesquisa são os textos legais referentes ao tema, especialmente o Acordo TRIPS, a Lei de Patentes (Brasil) e a Lei n. 12.598/12, e os documentos das políticas de defesa (Política Nacional de Defesa e Estratégia Nacional de Defesa), e de propriedade intelectual e offset do Ministério da Defesa (PN n. 1.888/10 e PN n. 764/02) e seus comentários. O Acordo TRIPS prevê exceção à liberdade do comércio em defesa e deixa aos países a formulação de políticas de aquisição de produtos de defesa e tecnologia. A Política de Compensação Comercial... não traz dispositivos acerca de propriedade intelectual. O enfoque da Política de Propriedade Intelectual está nas patentes, não no segredo empresarial ou no know-how. A hipótese confirmou-se, mas foram identificadas inconsistências nas políticas: a ausência de diretrizes quanto a medidas concretas de proteção dos segredos pode descaracterizá-los, conforme o Acordo TRIPS, e o enfoque em patentes não toma em consideração que tecnologias sensíveis associam segredos industriais a patentes, sem que haja diretrizes especificas do licenciamento daqueles.
Abstract : The compatibility of the offset policy of the Brazilian Ministry of Defence with the international legal framework for the protection of know-how. The import of defense technologies, despite the countries claim for autonomy and in the sake of legal certainty, must be in compliance with the international regimes and the domestic legal systems of the sellers. The incompatibility between the policies of acquisition and management of knowledge must be assessed in relation to international and foreign regulation and may risk legal uncertainty and the imposition of international sanctions. This study investigates the compatibility of the offset policy of the Brazilian Ministry of Defence with the international regime for the know-how protection in international transfers of technology. The purpose of the research is to identify possible inconsistencies, in order to guide public policies. The hypothesis is that there is full coherence between them. The issue will be addressed with regard to the positivistic theory (dogmatic approach). The method of approach is deductive. The basic documents of research are the legal texts, especially the TRIPS Agreement, the Patent Act (Brazil) and Law n. 12,598/12 (Brazil), the official Brazilian defense policies (National Defence Policy and National Defense Strategy) and the Ministry of Defence s intellectual property and offset policies (PN n. 1.888/10 e PN n. 764/02). The TRIPS Agreement provides an exception to free trade in the defense area and grants the countries autonomy in the formulation of technology and defense products acquisition policies. The offset policy does not address directly intellectual property. The intellectual property policy is focused in patents, not in trade secrets or know-how. The hypothesis was confirmed, but some policy inconsistencies were identified: the absence of guidelines on concrete measures for the protection of trade secrets can strip them of one of their requirements, as stablished in the TRIPS Agreement, and the focus on patents does not take into account that sensitive technologies usually associate trade secrets and patents and there is no specific guidelines concerning the licensing of the formers.

Повний текст джерелаIn France, the objective of ecological compensation for residual impacts on biodiversity is to achieve no net loss of biodiversity. A normative framework setting out about ten principles theoretically makes it possible to achieve this objective.We are therefore studying the implementation of biodiversity offset through three High Speed Railway projects. We analyze the actor's game around this implementation through the theories of collective action, and in particular the analytical framework of Translation proposed by M. Callon. This first analysis allows us to understand how biodiversity offset is a socio-technical object. We highlight that many actors with diverging stakes are mobilizing to implement ecological compensation. We show that there is a tension between the mobilization of actors and ecological requirements, these two aspects are not always compatible. The duration of the environmental services specifications and the associated retribution of landowners, who set-up biodiversity offset specification, is decisive for both human and non-human (biodiversity) mobilization. We then question the temporal spatial effects of collective action and its ability to achieve a net loss of biodiversity. We show that the measures could not be effective before the impacts began. Land management in France seems for the moment to be difficult to reconcile with the implementation of unanticipated biodiversity offset at a very early stage. We show that the majority of biodiversity offset sites are small in size, although larger areas seem more virtuous for biodiversity. Finally, we show that the sustainability of biodiversity offset measures can be assessed at different levels depending on (i) the type of land control (acquisition, agreement); (ii) biodiversity offset contracts (duration, content of the latter - sanctions in the event of failure to comply with obligations influence the maintenance of the measures); (iii) the management of the renewal of these contracts; (iv) the vocation of the owners of the sites (a public or private construction company does not initially have the role of conserving biodiversity, whereas an environmental NGO has the vocation); (v) the sustainability of the structures and assurances as to the future of the biodiversity offset measures sites in the event of bankruptcy; (vi) the monitoring and control of the implementation

Повний текст джерелаIn light of the global erosion of biodiversity caused by human activities, biodiversity offsets and, more broadly the Mitigation Hierarchy, are increasingly used since the 1970s, with the ambition of reconciling economic development and biodiversity conservation. Its objective is to achieve "No Net Loss" (NNL) of biodiversity. One of the key issues to achieve this goal is to demonstrate ecological equivalence between the gains from offsets and the losses caused by impacts. Despite regulatory improvements, the French law does not include a method for assessing equivalence, and no method is unanimously recognized. This leads to heterogeneous practices and difficulties in reaching the NNL objective. In this context, this thesis aims to develop a standardized methodological framework (SMF) for assessing equivalence, which combines operationality, scientific basis and comprehensiveness (taking into account the four dimensions of equivalence: ecological, spatial, temporal and uncertainties). First, 13 methods used abroad are analysed in order to identify structural elements for the development of a SMF adapted to the French context. The construction is decomposed into three steps. The first consists in selecting an organized set of indicators, on which equivalence assessment should be based in order to meet legislative requirements and reflect the complexity of biodiversity. The assessment is to be done at two spatial scales (on-site and within an expanded perimeter) and at three levels reflecting general or specific issues (habitat or species). The second step regards the prediction of the values of the indicators over time, consequently to the impacts and offsets, taking into account the implied uncertainties. The third step leads us to establish rules for calculating losses and gains, as well as for the overall assessment of equivalence. Finally, this SMF is tested on two study sites in order to demonstrate the added value and to identify its limits. Prospects for improving the SMF, and more broadly the evaluation of equivalence, are then suggested. Finally, all these elements make it possible to question the effectiveness of offsets in order to tackle biodiversity erosion

Повний текст джерелаThe major contribution of this thesis is to show that the growing role for biodiversity in territorial planning policies is firmly linked to the role played by impact assessment instruments, grouped together under the term 'environmental assessment'. By considering these instruments (impact studies, offset mechanisms, associated participatory processes) as 'co-productions', that is to say as instruments mixing elements of science and political decision-making, we showed that they had their own effects, which have strongly influenced planning policies and the way in which planning actors conceive of biodiversity.The study of environmental assessment instruments, following on the one hand a socio-historical approach and on the other a series of case studies of large-scale railway projects, allowed us to show the existence of several 'regimes' characteristic of environmental assessment, that mobilise different tools and different representations of biodiversity, and which we have identified as 'pioneering', 'institutionalised' and 'utilitarian'.The study of biodiversity in society can therefore be approached not only through analysing the conventions, law and conflicts between actors that it generates, but also through considering the concrete instruments implemented in order to take biodiversity into account, these instruments revealing the representations of biodiversity at a moment in time and being the vectors of change in these representations

Повний текст джерелаRespecto a la patrimonialidad del contrato,derivada de la patrimonialidad de la prestación, se ha escrito y propuesto mucho. Autores de diversas épocas e ideas han tocado eltema, siendo fundamental para entender los conceptos básicos de obligación y relacióncontractual. La postura mayoritaria encuentra el fundamento de la patrimonialidad dela prestación en ser un límite a la autonomía privada, ya que lo patrimonial, aquello susceptible de valor económico, no lo definen laspartes, si no el contexto social.En el presente artículo, el autor rechaza y discute dicha postura. Basándose en la libertad que tiene cada persona de definir lo más conveniente para sí y lo más eficiente en términos económicos, defiende una visión subjetiva de la patrimonialidad de la relación contractual y le da a la patrimonialidad de la prestación una función y un fundamento diferente: El ser indispensable para el cálculo de la indemnización en caso de incumplimiento.

Повний текст джерелаThe installation of marine renewable energies is carried out in compliance with French environmental legislation. The mitigation hierarchy is thus applied to achieve an objective of no net loss of biodiversity. This thesis aims at questioning the effectiveness of the mitigation hierarchy and more specifically biodiversity offsetting as an internalization instrument to halt the erosion of marine biodiversity. We use a qualitative empirical approach to (i) identify the ecological and societal factors as well as their theoretical characteristics that are supposed to enable the offsets achieving the objective of no net loss of biodiversity; and (ii) control whether these conditions are verified in practice for the case of offshore wind farms in Europe and France. The analysis highlights the legal, institutional, methodological and societal issues to be addressed in order to enable biodiversity offsetting to achieve the no net loss priority. On the basis of this observation, a multi-criteria assessment is carried out to reinforce the avoidance and reduction steps of the mitigation hierarchy in order to better define offsetting needs. Ultimately, the analysis shows a shift in biodiversity offsetting based on a strict ecological equivalence to a biodiversity offsetting based on a released ecological equivalence. Offsetting actions tend to be more generalist and / or more directed to ecosystem services than to ecosystem components. Associated with accompanying measures, offsetting actions can help to increase the social acceptability of a development project

Повний текст джерелаDespite some authors’ scepticism, the international environmental law can find certain solutions in the law of state responsibility. However, the success of finding such solutions depends on the introduction of a number of environmental considerations to as conditions of state responsibility, its invocation and reparation. Regarding the first, although the state responsibility, which is based on breach of obligations, may lack normative environmental aspect, its preventive role vis-a-vis the environmental harm should not be underestimated. As to the invocation, the positive law has to acknowledge the right of an injured state acting for the collective interest in order to include spaces and species beyond the state’s sovereignty to the law of state responsibility. Regarding the forms of reparation, restitution and compensation must be adapted taking into consideration the importance of environmental restoration towards baseline conditions. However, satisfaction needs to transform into a multiform and flexible form of reparation. For this purpose the present study suggests the biodiversity offset mechanism as a form of satisfaction

Повний текст джерелаBiodiversity offset, as the last step of the mitigation hierarchy (avoid/reduce/offset), aims to address the current biodiversity loss crisis. The main goal of this PhD, which relies on the new institutional economics approach as a theoretical framework, is to understand the organizational and institutional issues of implementing biodiversity offsets policies for impacts on continental and offshore wetlands in Europe and the United-States. Hierarchical organizations (i.e. permittee responsible mitigation) often lead to little to no implementation of biodiversity offsets because the ecological effectiveness of case-by-case compensatory measures is unproven and the monitoring and control of numerous measures are difficult. In the United-States, the mitigation banking system aims to compensate for multiple small impacts on wetlands by carrying out restoration projects on fewer but larger wetland areas in order to reach the goal of no net loss of biodiversity. This hybrid organizational form is highly regulated and therefore stands halfway between hierarchical and market organizations. However, actors have individual and collective strategies that generate negotiations with consequences on economic development and biodiversity conservation stakes. The mitigation banking system leads to a decrease of transaction costs and a change of the actors bearing them. It seems that the evolution of the whole framework of biodiversity offsets policy implementation in the United-States leans toward an institutional complementarity between these two organizational forms rather than a disappearance of hierarchical organizations

Повний текст джерелаGathered under the term “economic instruments” – or market-base instruments -, mechanisms for ecological compensation and payments for environmental services have established themselves as the essential tool for the biodiversity and ecosystem protection policies. Built around a plurality of principles (polluter pays principle, beneficiary pays principle, etc.) and concepts (ecosystem services, natural capital, etc.) largely influenced by economical approaches of biodiversity and ecosystems, these two instruments characterize the oncoming of a new take on environmental policies. The study reveals the plurality of judicial links that unite ecological compensation and payments for environmental services. Sometimes close together, sometimes distinguishable, these mechanisms are, in fine, both sides of a same coin. The use of payments for environmental services, as ecological compensation, appears however as a preoccupying orientation, likely to deflect this instrument from its purpose. In spite of their theoretical virtues, the efficiency of ecological compensation mechanisms and payments for environmental services for the protection of biodiversity turns out to be questionable, justifying a reinforcement and more consistency in their legal framework

Trafikverket har fått direktiv från regering att verka för ökad produktivitet och ökad innovationsgrad i anläggningsbranschen. Trafikverket har som ambition att förändra sin roll som beställare för att skapa förutsättningar för marknaden och dess drivkrafter till ökas innovation och produktivitet genom att överlämna ett större åtagande och ansvar till entreprenörerna. En strategisk huvudinriktning är att öka andelen totalentreprenader inom anläggningsbranschen. Entreprenader som avser investeringar mellan 25 – 500 Mkr ska 50 % av entreprenaderna upphandlas genom totalentreprenader. Syftet med denna rapport är att kartlägga hur marknaden ser på förfrågningsunderlaget med tonvikt på det objektspcifik tekniska beskrivningen, dess kalkylbarhet, struktur och tydlighet.

Intervjuer har utförts med entreprenörerna som har deltagit i anbudstävlingen. Syftet med intervjuerna har varit för att få entreprenörernas synpunkter på förfrågningsunderlaget som kan tas hänsyn till i kommande projekt. Svaren kommer analyseras av Trafikverket och tas i hänsyn till utvecklingsarbetet av framtida förfrågningsunderlag inom totalentreprenader för anläggningsbranschen. OTB för just sträckan Stenkumla – Dunsjö, tillåts inte entreprenörerna komma med innovativa lösningar eftersom förfrågningsunderlaget innehåller många tekniska lösningar som angivits av Trafikverket. Entreprenörerna vill ha mer frihet i förfrågningsunderlagen för att kunna bidra med innovativa lösningar. En anledning till att det finns många tekniska lösningar i detta projekt är att det finns en beslutad järnvägsplan. Järnvägsplanen styr utformningen av anläggningen.

Повний текст джерелаOver the past decades, biodiversity erosion has speeded up and become a global environmental concern since. Anthropization has led to. The mitigation hierarchy (avoidance, reduction and offsetting of impacts) is a regulatory tool implemented in a context of habitat destruction and fragmentation, disrupting species’ life cycle. The objective is to achieve “no net loss” of biodiversity following urban development. Although biodiversity conservation regulations have recently better addressed ecosystem functioning, the mitigation hierarchy is still being implemented with little concern for the spatial configuration of ecosystems in the landscape. This thesis hypothesizes that the major difficulties encountered by stakeholders are, in part, methodological and technical. Situating our research at the knowledge-action interface, we propose a methodological framework based on several modeling approaches, to respond to the different scientific and operational challenges. This thesis joins forces with other scientific projects and stakeholders’ networks by exploring complementary axes. To this end, we first integrate spatio-temporal issues of biodiversity into overall mitigation hierarchy application, focusing on potential impacts and dimensioning at “territorial development project” scale through a case study on the new stadium in Lyon (Southern France). Combining species distributions models and spatial graphs improves habitat connectivity and therefore the design of the development projects. Next, we demonstrate the positive impacts on peri-urban habitat connectivity of pooling and anticipating offsets in the suburbs of Lyon. In the last part, we demonstrate the implications of an anticipated and planned approach to the mitigation hierarchy on a planning scale. We consider both ecological connectivity and urban dynamics, in an attempt to minimize the ecological impacts of urban sprawl by avoiding urbanization of areas of highest ecological value and then enhance the application of biodiversity offsetting. This method is tested on projections for the Toulouse conurbation (Southern France) by 2040. Thus, this thesis presents an overall approach that can help to increase habitat connectivity and to improve the design of territorial development projects at different spatial and temporal scales. This methodology is based on freeware available to all practitioners. It will serve planners, designers, and decision-makers needing to ensure that there are no significant or irreversible effects on biodiversity, and environmental authorities making sure that all environmental issues are taken into account in the design of development projects
Marek, Ewelina. "Essays on mental accounting effects of personal carbon allowances : implications for transportation." Thesis, Lyon, 2016. http://www.theses.fr/2016LYSE2083.
Повний текст джерелаThe excessive anthropogenic activities related to burning of fossil fuels emit around 80 percent of greenhouse gases (GHG) in the atmosphere per year, according to the Intergovernmental Panel on Climate Change (IPCC, 2014). Among the GHG emissions, the anthropogenic CO2 emissions belong to the most dangerous ones. About 40 percent of these CO2 emissions have remained in the atmosphere (880 ± 35 GtCO2) since 1750, contributing to the global warming effect (IPCC, 2014). Since the 1950s, humanity is clearly responsible for more than half of the observed increases in temperatures (IPCC, 2014). The world energy consumption in 2011 tripled when comparing to 1965 and it has increased more rapidly than the world population (BP and UN, 2012). The above problem concerns a number of sectors, but only one of them has become the main subject of this dissertation. More precisely, this dissertation focuses on the transportation sector, which belongs to one of the greatest contributors of CO2 emissions to the atmosphere ((EC, 2012). Researchers warn that if the personal transportation demand continues to augment, which is likely due to the steady increase in population and greater accessibility to transport modes, the levels of congestion could become intolerable and even more costly to mitigate (Stern, 2006; EEA, 2010; Ostrom et al., 2012). Lack of changes in individual’s behavior, irrespectively of investment in abatement technologies, could lead to excessive costs, which already today are estimated to be high due to a very few low-carbon alternatives available (Abrell, 2007; Bottrill, 2006; Proost, 2008; SDC, 2005). The essays presented in this dissertation shed some light on how insights from the behavioral economics could be used to tackle the environmental pollution from personal transportation. At the core, lies the implementation of a market-based policy instrument (i.e., personal carbon allowances) in hypothetical commuting choices. The personal carbon allowances, abbreviated as PCA, constitute “a right to pollute” the atmosphere during personal activities, such as commuting and traveling (Roberts and Thumim, 2006; Howell, 2008; 2012; Parag et al., 2011). This dissertation provides suggestions on how a PCA design could influence personal choices of commuting. On the basis of four essays, a number of conclusions were drawn, and policy recommendations were formulated. For the purposes of this dissertation, PCA was defined to be any ‘cap-and-trade’ public policy instrument in which carbon emission rights are allocated to individuals. Three out of four essays encompassed laboratory experiments. The experimental subjects managed their allowances under a term emission permits (les permis d'émission, in French) because the study was conducted in France. One of the conclusions that should be highlighted is that the labeling effect had a positive influence on the experimental subjects and that it would be beneficial to consider it in the PCA scheme. For example, the personal carbon allowances that are granted for all activities could be extended by allowances that would be valid for public transportation only. The public transportation should be labeled in the budget because it is a less polluting alternative to private transportation. Having a certain number of allowances for public transportation at their disposal, subjects may be more willing to use this transport mode in replacement of commuting by private transportation. Another lesson that can be drawn from this dissertation is that the provision of feedback matters. Moreover, individuals may not only rely on their personal past experiences but also may want to extend their knowledge by the feedback on activities of their peers or neighbours

With the development of the computer science, computer aided software is applied in several areas. Especially, the computer aided design is applied on many industries. For example, the CNC machining is important in the manufacture of the product. In the progress of the NC tool path simulation, it should have the inseparable geometry association of offset curve and offset surface. The research focuses on the improvement of the surface offset method, by combining the advantages of using the data point and the control point for the construction of the offset surface. After the mutually application, finding the start position of the critical point, and using the golden search for the optimum local maximum and minimum is the key achievement of the proposed thesis. From the topological structure of the boundary curve and the base surface, the proposed method can be extended to the offset of the trimmed surface.

In OFDMA uplink system, the oscillator mismatch between transmitter and receiver destroys the orthogonality among subcarriers. Unlike downlink, the carrier frequency offsets (CFOs) in uplink system not only cause phase shift and inter-carrier interference (ICI) but also multiple access interference (MAI). Thus, how to estimate and compensate the CFOs becomes a crucial task. For this reason, many MAI compensation methods have been proposed but they still suffer from MAI effect. Therefore, we propose an MAI cancellation scheme that improves the MAI that is caused by CFOs. Using simulation results, we show that the proposed method effectively cancels the MAI effect and we also verify that the performance of our proposed method is better than the other previous works.

There are two types of RF front-end imperfections in most communication devices, the frequency offset and the IQ imbalance, namely and respectively. The two effects can affect serious impact on performance. This study proposes a novel scheme which adopts the Least Square (LS) method to estimate the IQ imbalance when the frequency offset effect exists by using a preamble of repeated training sequence. An analogous scheme to estimate the frequency offset was also developed in this study when the IQ imbalance effect exists. These proposed schemes were applied in IEEE 802.11a standard and validated their performance by simulation.

We propose a capacitor sharing method for multi-stage offset compensation. The offset voltage of the 1st stage can be compensated using the difference of voltages at output between two phases. The offset voltage of the 2nd stage can be canceled using a closed loop auto-zero compensation technique ( input storage ). Only one capacitor is required for a multi-stage circuit in case of single-ended implementation. The method can be applied to many types of a multi-stage circuit. Such as comparators, frequency shift keying (FSK) signal process system and so on. In the application of comparators, for example, only one capacitor is needed between two pre-amplifiers that are serial connection to compensate offset voltages. We proposed three comparator circuits with switched-capacitor amplifiers or switched-resistor amplifiers based on ping-pong structure. They can increase the active time. Similarly in the FSK signal process system, only one capacitor is needed between the high-pass filter and hysteresis limiter that are serial connection to compensate offset voltages. Such a circuit is mixed-signal mode, and thus we need to use the CADANCE tools to design the circuit. The HSPICE simulation of the designed compensation circuit shows that the input offset voltage can be reduced to less than 0.3%. It is realized by using TSMC 0.35mm CMOS process. The measurement result shows that we can reduce the offset voltage to mv level. The results prove that the capacitor sharing method is useful for multi-stage offset compensation.

Orthogonal frequency division multiplexing (OFDM) is a promising transmission technology for future high data rate communications. OFDM has been used in wide varieties of applications. In this thesis, the issues of clock offset and I-Q imbalance of OFDM systems are investigated. A novel open-loop phase-tracking with phase interpolation is proposed to counteract the effect of clock offset. In addition, three new compensation methods for I-Q imbalance that appears in the direct conversion RF frond-end are proposed. Simulations on the IEEE 802.11a OFDM WLAN system show that the implementation loss due to clock offset estimation is less than 1 dB, and the proposed new methods for I-Q imbalance compensation significantly outperform the traditional ones. Finally, a complete transceiver that complies with the IEEE 802.11a specification is designed and simulated. The overall implementation loss is less than 2 dB.

For the orthogonal frequency division multiplexing (OFDM) system, carrier frequency offset (CFO) leads to loss of orthogonality among subcarriers; thus significantly degrading bit error performance. Moreover, in the uplink orthogonal frequency division multiple access (OFDMA) system, multiple CFOs due to multi-user result in multiple access interference (MAI), further degrading system performance. Particle Swarm Optimization (PSO) is one potential scheme for CFOs estimation, however, its performance gradually degrades with the increasing number of users due to the lack of diversity. While attractive and repulsive PSO (ARPSO) can enhance diversity using attraction and repulsion operators, its convergent speed is very slow. Therefore, this study proposes a modified PSO, which is called MRPSO for simplicity, to improve mean square error (MSE) performance and convergent speed of PSO by integrating mutation and repulsion operators. Additionally, least square (LS) is employed to mitigate the effect of ICI and MAI. Simulation result indicates that our proposed scheme is superior to LPSO_Mut and ARPSO for CFOs estimation and compensation.

Orthogonal Frequency-Division Multiple Access (OFDMA) is a popular physical layer technique for wireless communication nowadays. Due to carrier frequency offset caused by local oscillator mismatch and Doppler Effect, frequency synchronization is a crucial issue for mobile communication. Although many literatures have proposed lots of solutions for OFDMA downlink, there are still lots of problems that degrade the performance in uplink. At the beginning of this thesis, the pilots are inserted in transmitting signals to assist the CFO estimation. With the iterative algorithm, the perfect CFO estimation is achieved at the second iteration. In addition, we also try to exploit the banded matrix to reduce the computational complexity of the full matrix. Therefore, exploiting from such scheme, the low complexity estimation is obtained without sacrificing much performance. Second, in the later chapter, we consider the problem of the unequal power allocation to the base station. Unequal power users would make strong multiuser interference on our estimation and degrade our performance. Therefore, in order to acquire better performance, a modified method is proposed to eliminate the interference before the estimation. Finally, considering practical implementation, we would set the environment to that of Taiwan High Speed Rail. With the proposed algorithm, the estimation performance can achieve the same quality in time-invariant channels.
