Techniques for Uncertainty quantification, Risk minimization, with applications to risk-averse decision makingAshish Chandra (12975932) 27 July 2022 (has links)
<p>Optimization under uncertainty is the field of optimization where the data or the optimization model itself has uncertainties associated with it. Such problems are more commonly referred to as stochastic optimization problems. These problems capture the broad idea of making optimal decisions under uncertainty. An important class of these stochastic optimization problems is chance-constrained optimization problems, where the decision maker seeks to choose the best decision such that the probability of violating a set of uncertainty constraints is within a predefined probabilistic threshold risk level. Such stochastic optimization problems have found a lot of interest in the service industry as the service providers need to satisfy a minimum service level agreement (SLA) with their customers. Satisfying SLA in the presence of uncertainty in the form of probabilistic failure of infrastructure poses many interesting and challenging questions. In this thesis, we answer a few of these questions.</p>
<p>We first explore the problem of quantifying uncertainties that adversely impact the service provider's infrastructure, thereby hurting the service level agreements. In particular we address the probability quantification problem, where given an uncertainty set, the goal is to quantify the probability of an event, on which the optimal value of an optimization problem exceeds a predefined threshold value. The novel techniques we propose, use and develop ideas from diverse literatures such as mixed integer nonlinear program, chance-constrained programming, approximate sampling and counting techniques, and large deviation bounds. Our approach yields the first polynomial time approximation scheme for the specific probability quantification problem we consider. </p>
<p>Our next work is inspired by the ideas of risk averse decision making. Here, we focus on studying the problem of minimizing risk functions. As a special case we also explore the problem of minimizing the Value at Risk (VaR), which is a well know non-convex problem. For more than a decade, the well-known, best convex approximation to this problem has been obtained by minimizing the Conditional Value at Risk (CVaR). We proposed a new two-stage model which formulates these risk functions, which eventually leads to a bilinear optimization problem, a special case of which is the VaR minimization problem. We come up with enhancements to this bilinear formulation and use convexification techniques to obtain tighter lower and upper convex approximations to the problem. We also find that the approximation obtained by CVaR minimization is a special case of our method. The overestimates we construct help us to develop tighter convex inner approximations for the chance constraint optimization problems.</p>

La mise en oeuvre de la responsabilité civile dans le dispositif juridique régissant les recherches biomédicales : Une étude comparative entre le droit français et le droit irakien / Civil liability implementation in the legal system regulating biomedical research : Comparative study between French and Iraqi law / النظام القانوني لتنفيذ البحث الطبي الحيوي على الكائن البشري والمسؤولية المدنية الناجمة عنه دراسة تحليلية لنظام المسؤولية المدنية الخاص في القانون الفرنسيAl iftaihat, Yassir 20 December 2011 (has links)
Les recherches biomédicales se sont imposées comme une nécessité sociale et leur place n’a pas cessé de prendre de l’importance dans le domaine médical. Leur encadrement juridique commence en 1988 avec la loi « Huriet », qui vient de mettre en place un régime de responsabilité civile régissant cette activité.Ce régime renforce la protection des victimes (et de leurs ayants droit) de recherches biomédicales en simplifiant la procédure d’indemnisation. Seul le tribunal de grande instance est compétent pour connaître des litiges en la matière et ce même s’il s’agit d’un promoteur du secteur public qui relève normalement du juge administratif. Le délai de prescription est de dix ans car les dommages ne peuvent pas apparaître immédiatement après la fin de la recherche. La victime et ses ayants droit peuvent demander l’indemnisation des dommages matériels et moraux subis à l’occasion de la réalisation de la recherche. Dans les cas où la responsabilité du promoteur n’est pas engagée, la victime peut toujours demander une indemnisation à l’ONIAM, en déposant une demande auprès de la CRCI. La loi « Huriet » devrait concilier l’intérêt de la société avec ses valeurs fondamentales, et trouver le juste équilibre permettant d’assurer une protection parfaite aux individus se prêtant à ces recherches, sans entraver leur développement. / Biomedical research has emerged as a social necessity. Its importance has continued to grow in the medical field. Its legal framework began in 1988 with the law "Huriet", which established a civil liability governing this activity.Today’s legal system increases the protection of victims (and their dependents) of biomedical research by simplifying the procedures for plaintiffs to receive compensation. Only the High Court has the jurisdiction to hear disputes in this area and even if he is a proponent of the public sector is normally the administrative judge. The limitation period is ten years since the damage may not appear immediately at the end of the research. The victim and his/her dependents are entitled to compensation for material and moral damages incurred in connection with the conduct of research. In cases where the liability of the promoter is not involved, the victim can still claim compensation from the ONIAM by filing an application with the CRCI.The law "Huriet" should reconcile the interests of the society with its core values, and find the right balance to ensure a perfect protection to individuals suitable for this research, without hindering their development. / لقد فرضت الابحاث الطبية الحيوية كضرورة اجتماعية واتخذت أهمية لا يمكن الاستغناء عنها في المجال الطبي. وحيث ان تنفيذها على الكائن البشري أصبح مطردا، فان إحاطتها بقانون متكامل أصبح امرا لا مفر منه، وقد بدأ ذلك الأمر بتشريع قانون عام 1988 والذي اتى بالجديد عندما أحاط تنفيذ الابحاث الطبية على الكائن البشري بنظام مسؤولية مدنية. هذا النظام هدفه تدعيم حماية المشاركين بالبحث من خلال تعويض المتضرر منهم او خلفه العام من خلال تبسيط اجراءات التعويض. فحدد هذا القانون الاختصاص حصريا بالمحكمة البدائية في النظر بالخصومات المتعلقة بتنفيذ الابحاث الطبية على الكائن البشري، حتى لو كان القائم على تنفيذ البحث شخص من القانون العام. والذي من المفترض ان يكون الاختصاص حينها للقاضي الاداري. هذا وقد حدد قانون عام 1988 مدة التقادم بعشرة سنوات من وقت انتهاء تنفيذ البحث، لان الاضرار قد لا تظهر إلا بعد مدة من تنفيذ البحث. فالمتضرر أو خلفه العام يستطيعون المطالبة بالتعويض على الاضرار المادية والادبية التي نجمت عن تنفيذ البحث الطبي. لكن في حالة اثبات عدم وجود خطا من القائم بالبحث الطبي أي انه غير مسؤول عن الاضرار، فان المتضرر يحق له حينها بموجب هذا القانون اللجوء إلى المطالبة بالتعويض من خلال الهيئة الوطنية للتعويض عن الحوادث الطبية. خلاصة القول، إن قانون عام 1988 سعى لايجاد موازنة ما بين الفائدة التي تعود على المجتمع من تنفيذ البحث وبين ضمان حماية المشارك بالبحث بالشكل الذي يكفل حرمة الجسد البشري دون ان يؤدي ذلك إلى وضع العقبات أمام تنفيذ الابحاث الهامة للمجتمع

On Rules and Methods: Neural Representations of Complex Rule Sets and Related Methodological ContributionsGörgen, Kai 20 November 2019 (has links)
Wo und wie werden komplexe Regelsätze im Gehirn repräsentiert? Drei empirische Studien dieser Doktorarbeit untersuchen dies experimentell. Eine weitere methodische Studie liefert Beiträge zur Weiterentwicklung der genutzten empirischen Methode. Die empirischen Studien nutzen multivariate Musteranalyse (MVPA) funktioneller Magnetresonanzdaten (fMRT) gesunder Probanden. Die Fragestellungen der methodischen Studie wurden durch die empirischen Arbeiten inspiriert. Wirkung und Anwendungsbreite der entwickelten Methode gehen jedoch über die Anwendung in den empirischen Studien dieser Arbeit hinaus.
Die empirischen Studien bearbeiten Fragen wie: Wo werden Hinweisreize und Regeln repräsentiert, und sind deren Repräsentationen voneinander unabhängig? Wo werden Regeln repräsentiert, die aus mehreren Einzelregeln bestehen, und sind Repräsentationen der zusammengesetzten Regeln Kombinationen der Repräsentationen der Einzelregeln? Wo sind Regeln verschiedener Hierarchieebenen repräsentiert, und gibt es einen hierarchieabhängigen Gradienten im ventrolateralen präfrontalen Kortex (VLPFK)? Wo wird die Reihenfolge der Regelausführung repräsentiert? Alle empirischen Studien verwenden informationsbasiertes funktionales Mapping ("Searchlight"-Ansatz), zur hirnweiten und räumlich Lokalisierung von Repräsentationen verschiedener Elemente komplexer Regelsätze.
Kernergebnisse der Arbeit beinhalten: Kompositionalität neuronaler Regelrepräsentationen im VLPFK; keine Evidenz für Regelreihenfolgenrepräsentation im VLPFK, welches gegen VLPFK als generelle Task-Set-Kontrollregion spricht; kein Hinweis auf einen hierarchieabhängigen Gradienten im VLPFK.
Die komplementierende methodische Studie präsentiert "The Same Analysis Approach (SAA)", ein Ansatz zur Erkennung und Behebung experimentspezifischer Fehler, besonders solcher, die aus Design–Analyse–Interaktionen entstehen. SAA ist für relevant MVPA, aber auch für anderen Bereichen innerhalb und außerhalb der Neurowissenschaften. / Where and how does the brain represent complex rule sets? This thesis presents a series of three empirical studies that decompose representations of complex rule sets to directly address this question. An additional methodological study investigates the employed analysis method and the experimental design. The empirical studies employ multivariate pattern analysis (MVPA) of functional magnetic resonance imaging (fMRI) data from healthy human participants. The methodological study has been inspired by the empirical work. Its impact and application range, however, extend well beyond the empirical studies of this thesis.
Questions of the empirical studies (Studies 1-3) include: Where are cues and rules represented, and are these represented independently? Where are compound rules (rules consisting of multiple rules) represented, and are these composed from their single rule representations? Where are rules from different hierarchical levels represented, and is there a hierarchy-dependent functional gradient along ventro-lateral prefrontal cortex (VLPFC)? Where is the order of rule-execution represented, and is it represented as a separate higher-level rule? All empirical studies employ information-based functional mapping ("searchlight" approach) to localise representations of rule set features brain-wide and spatially unbiased.
Key findings include: compositional coding of compound rules in VLPFC; no order information in VLPFC, suggesting VLPFC is not a general controller for task set; evidence against the hypothesis of a hierarchy-dependent functional gradient along VLPFC.
The methodological study (Study 4) introduces "The Same Analysis Approach (SAA)". SAA allows to detect, avoid, and eliminate confounds and other errors in experimental design and analysis, especially mistakes caused by malicious experiment-specific design-analysis interactions. SAA is relevant for MVPA, but can also be applied in other fields, both within and outside of neuroscience.

Satisticing solutions for multiobjective stochastic linear programming problemsAdeyefa, Segun Adeyemi 06 1900 (has links)
Multiobjective Stochastic Linear Programming is a relevant topic. As a matter of fact,
many real life problems ranging from portfolio selection to water resource management
may be cast into this framework.
There are severe limitations in objectivity in this field due to the simultaneous presence
of randomness and conflicting goals. In such a turbulent environment, the mainstay of
rational choice does not hold and it is virtually impossible to provide a truly scientific
foundation for an optimal decision.
In this thesis, we resort to the bounded rationality and chance-constrained principles to
define satisficing solutions for Multiobjective Stochastic Linear Programming problems.
These solutions are then characterized for the cases of normal, exponential, chi-squared
and gamma distributions.
Ways for singling out such solutions are discussed and numerical examples provided for
the sake of illustration.
Extension to the case of fuzzy random coefficients is also carried out. / Decision Sciences

Freedom of InterpretationIvanov, Georgi 11 May 2012 (has links)
The photographic series Ideal Cities that I started in 2011 is inspired by the conflict between my idea of the “west” and my evolving experience in the United States. What struck me was the popularity of what I see as model experience – a spatial experience controlled by the Spectacle. In the terms of the Situationist International and its most prominent figure Guy Debord, the Spectacle is the collapse of reality into the streams of images, products and activities sanctioned by centralized monopolist business or state bureaucracy. Thus, personal experience is replaced with preconceived notions, which control the way people perceive and understand their surroundings.

La responsabilité précontractuelle : étude comparative des régimes colombien et français / Pre-contractual liability : study in comparative law between the Colombian and French law systemsMartinez-Cardenas, Betty Mercedes 17 April 2013 (has links)
La responsabilité précontractuelle dérive de la transposition du devoir d'agir de bonne foi qui pèse sur les contractants au stade de l'exécution du contrat à celle de sa formation. En Colombie, cette transposition s'est faite en 1971 par voie législative dans le Code du commerce alors qu‟en France elle s'est produite grâce à la jurisprudence. Toutefois, le caractère répressif de la responsabilité au stade de la formation du contrat est encore conçu, au mieux, comme une simple réminiscence de la responsabilité délictuelle et, au pire, comme une sanction marginale à la responsabilité contractuelle. L'intérêt qui existe dans cette recherche en droit comparé consiste, en effet, à trouver le critère qui donne à la responsabilité précontractuelle son autonomie, sa spécificité. Ainsi, une observation attentive nous a permis de découvrir que ceux qui persistent à nier l‟existence de la responsabilité précontractuelle en la rattachant à la délictuelle se sont penchés sur un critère chronologique emprunté à l'ancienne notion du contrat : le moment de sa conclusion. En effet, d'après eux, l'absence de contrat justifie que l'on applique le principe général de responsabilité délictuelle. Pourtant, la comparaison des régimes colombien et français montre la fragilité de ce raisonnement face aux nombreuses victimes des vices du consentement qui, de plus en plus, préfèrent l'indemnisation du dommage à la nullité du contrat. Une fragilité qui se révèle d‟autant plus évidente face aux dommages-intérêts qui sont accordés par les juges dans des contrats bel et bien formés, mais qui ne correspondent pas aux fautes dans l'exécution des obligations qui en découlent, mais aux fautes au stade de sa formation. En essence, l'identification des points de convergence ou de divergence de ces droits au stade de la formation du contrat, et leur comparaison par rapport aux mutations du régime de la bonne foi semblent, en effet, contribuer au renforcement de la responsabilité précontractuelle en tant qu'institution autonome. / Pre-contractual liability is derived from the transfer of the duty of the contracting parties to act in good faith from the contract performance phase to the contract formation phase. This transfer was carried out in Colombia by legislative action through the 1971 Commerce Code and in France, by jurisprudence. Nevertheless, the repressive nature of liability during contract formation is still interpreted as simply a reminiscence of delictual liability, at best, and as a marginal sanction for contractual liability, at worst. The goal of this study in comparative law is to find a criterion that confers autonomy and specificity to pre-contractual liability. Therefore, careful analysis by the author led to the discovery that those who insist on denying the existence of pre-contractual liability by linking it to delictual liability have based their argument on a chronological perspective taken from the old notion of contract, i.e., the time of execution. Furthermore, in their view, the absence of a contract justifies the application of the non-contractual liability regime. However, a comparison of the Colombian and French systems on this matter shows the fragility of the argument when faced with the large number of victims of defects of consent who, day after day, prefer indemnification of damages instead of a ruling of nullity of contract. This fragility is much more evident when judges order the indemnification of damages in well-formed contracts, due not to faults related to failure to meet any of the obligations that are derived from them, but to faults originating in the contract formation phase. In essence, finding common ground and discrepancies between the Colombian and French law systems regarding the contract formation phase and comparing them with the mutations of the good faith regime seem to actually contribute to consolidating pre-contractual liability as an autonomous institution.

德國梅克爾政府對中國政策之研究（2005-2009） / The research of the Merkel's policy toward China(2005-2009)劉育銘, Liu, Yu Ming Unknown Date (has links)
時至中國崛起的今日，世界上任何一國都無法忽略中國的存在。中國在改革開放後，憑著眾多的人口及豐富的資源，逐漸加強在國際上的影響力。各國遂加強與中國的關係，德國政府也不例外，在冷戰結束統一後，科爾總理即發表亞洲政策，宣佈加強與亞洲國家特別是中國的關係。繼任的德國總理施洛德則在對外政策上更加親中，曾三度訪問中國，經貿合作尤為其重點。2005年上任的梅克爾卻採取疏遠中國的作法，視中國為競爭對手。不但在新的亞洲戰略決議上建議加強亞洲國家如日本、澳洲以及印度的關係以圍堵中國，更以人權外交的名義持續給中國施加壓力。
而本論文就是以層次分析來研究梅克爾的對中外交政策，期望能以國際、國內以及個人因素來分析梅克爾政府與前任政府相比，來找出影響對中政策上轉變的原因。另外德國有著基本的外交政策，即基本保護德國的利益不會改變變，筆者也希望能找出其中變與不變之處，並分析這些基本外交政策對於中國政策的影響。 / “China rising” now is a hot topic in International affairs. By most population around the world and vast territory, China is gradually increasing its influence toward the international society. Many nations have seen this and tried to intensify bilateral relationship with China. Germany did so too. Following end of the Cold War, German Chancellor Helmut Kohl issued a file called “Asian policy” to strengthen the relation between the asian partner especially China. The Successor of Kohl, Gerhard Schröder, was following the rules even much closer toward China. In his term of chancellor, he has visited China as much as three times with a lot of business. Angela Merkel replaced Schröder in 2005 to be the new german Chancellor. Her party issued “Asia as strategic challenge and chance for Germany and Europe” to regard China as competitor of trade and tactic. Merkel also gave a lot of pressure with “Human Rights” to China.
This Article is for Merkel’s foreign policy toward China with “Level-Analysis”. Author expects to find the shift of the foreign policy toward China from Schröder to Merkel. In another part, Germany has its framework of the basic foreign policy. We should know that the german vital interest with protecting business can’t be changed. But there are still slight differences between each german government. That’s why author wants to find it in this thesis.
