Abstract:
Résumé Un fondement possible de l’analyse anthropologique de l’être humain de l’avenir serait la philosophie de Sloterdijk qui renouvelle celle de Nietzsche. Si l’on prend comme exemple d’une telle analyse le cas des « minorités nationales » des États-nations, les données semblent dessiner la coexistence négociée comme le modèle de base du posthumanisme. Ce modèle, exigeant beaucoup de complicité entre les ethnies et niveaux hiérarchiques, promet d’amener des combats mondiaux d’auto-détermination et dépendra beaucoup des structures intermédiaires qui communiquent entre les communautés. L’article analyse en détail les rôles des intermédiaires et la nouvelle philosophie qui sous-tendent ces rôles, où le souverainisme tiendra le rôle clef d’agent de sécurité des mouvements alternatifs.

Abstract:
Cette thèse s'intéresse aux effets de l'environnement concurrentiel de l'entreprise sur la rémunération incitative et sur l'effort de son dirigeant. Elle comporte trois essais, traitant chacun d'un aspect spécifique de cette problématique. En premier lieu, nous étudions, au travers d'un modèle théorique, le schéma de rémunération optimal et le niveau d'effort à l'équilibre. L'effet de la concurrence est analysé par l'entrée d'une entreprise sur un marché monopolistique. Ainsi, nous comparons les schémas de rémunération et le niveau d'effort du dirigeant entre ceux caractéristiques d'une situation de monopole et d'un duopole à la Cournot. Ce modèle est ensuite étendu à l'hypothèse d'aversion à l'inégalité. Nous montrons que l'entrée d'une entreprise affecte négativement la rémunération incitative et le niveau d'effort. Aussi, face à un dirigeant averse à l'inégalité, l'entreprise doit proposer une rémunération plus élevée afin d'implémenter le même niveau d'effort. En second lieu, nous examinons grâce à l'outil expérimental les prédictions théoriques de ces deux modèles. Nous confirmons ainsi que l'entrée d'une entreprise sur le marché réduit la rémunération incitative du dirigeant. En revanche, malgré cette réduction, le dirigeant continue à fournir le même niveau d'effort. Enfin, en troisième lieu, nous introduisons dans une nouvelle expérience la compétition entre les dirigeants en créant un différentiel de rémunération. Nous montrons que cette compétition permet à l'entreprise de réduire encore la rémunération de son dirigeant en duopole. De plus, le dirigeant compare sa rémunération avec le profit de son entreprise d'une part et avec celle de l'autre dirigeant d'autre part et cette double comparaison affecte son niveau d'effort
This dissertation analyzes the effects of the competition on the managerial incentives and effort. The dissertation is made of three essays, each dealing with a particular aspect of the general setting. Firstly, based on a model, we focus on the compensation schemes and the effort level of the manager in equilibrium. We examine the effects of a firm entry on the monopolistic market on these schemes and on the effort level. In this model we then introduce an additional assumption that managers are averse to inequity. We show that the firm entry affects negatively both the incentive compensation and the effort level. Furthermore, the firm has to propose a high compensation so as to implement the same effort level if the manager is inequity averse. Secondly, we test the theoretical predictions of these models in the laboratory. We confirm that the firm entry reduces the incentive compensation. In return, the manager continues to supply the same effort level in spite of the reduction of the incentive compensation. Finally, we implement, in a new experiment, the competition between the managers. We show that the competition allows the firm to reduce the compensation for her manager in the duopoly environment. Furthermore, the manager compares his compensation to the firm's profit and to the other manager's compensation. These comparisons have significant effects on the manager's level of effort

Abstract:
Dans un plan d'expériences constitue de parcelles de culture voisines, tout traitement applique a une parcelle peut avoir non seulement un effet direct sur cette parcelle mais également des effets - dits résiduels - sur les parcelles voisines. De ce fait les traitements peuvent entrer en compétition. Ce travail est consacre a l'étude de ce type de plans d'expériences en se limitant au cas des séquences, c'est-à-dire des plans constitues de parcelles alignées. Plus précisément, nous recherchons ici des plans optimaux pour l'estimation des effets directs, des effets résiduels ou d'autres effets comme les effets dits plein-champs. Nous considérons tout d'abord des plans constitues d'une seule séquence. Nous distinguons deux cas selon que la compétition s'exerce dans un sens ou dans les deux sens. Nous nous intéressons ensuite aux plans dans lesquels les parcelles sont elles-mêmes subdivisées en deux lignes qui reçoivent toutes deux le même traitement. Nous distinguons deux types de plans selon qu'ils sont constitues d'une seule séquence en blocs ou de plusieurs séquences formant chacune un bloc. En annexe, nous présentons plusieurs programmes d'analyse des plans expérimentaux étudies, et nous traitons quelques exemples

Abstract:
Nous présentons ici l'étude d'un problème de mécanique spatiale, le transfert en temps minimal vers une orbite géostationnaire. Plus précisément, nous nous intéressons à un cas particulier : le transfert mono-entrée. Reprenant les méthodes et les résultats des études précédentes, le transfert mono-entrée optimal est calculé et montre des performances excellentes compte tenu des contraintes supplémentaires introduites sur la direction de la poussée. Le contrôle optimal étant discontinu, nous introduisons deux approximations lisses. Nous considérons tout d'abord une approximation Riemanienne avec la moyennation du transfert en minimum d'énergie avec relaxation de la contrainte sur le contrôle : l'étude de la métrique Riemannienne associée montre que, dans des coordonnées adaptées, les trajectoires optimales sont des droites. Nous relions ensuite le transfert mono-entrée à des transferts bi-entrée contraints mais lisses et utilisons les conditions lisses du deuxième ordre sur ces approximations : cette procédure nous permet notamment de valider l'efficacité de la méthode de tir simple sur le transfert mono-entrée.

Abstract:
Les systèmes d'énergie électrique embarqués ou semi autonomes connaissent des évolutions marquées. Parmi elles, on peut citer l'introduction massive d'électronique de puissance permettant d'améliorer significativement les performances via leur commande et l'interfaçage de sources de stockage. A contrario, de nombreux problèmes se posent lors du dimensionnement et du choix de l'architecture de commande du système : quelle stratégie de gestion énergétique doit-on mettre en œuvre au préalable pour optimiser les flux et le dimensionnement des sources ? Quelle commande permet d'intégrer à la fois des critères de performances dynamiques, de stabilité et de robustesse vis-à-vis des incertitudes paramétriques inhérentes à un processus de dimensionnement ? Enfin, quels outils et modèles doit-on mettre en œuvre pour garder un lien fort entre paramètres du système et critères de performances tout au long de ce processus ? Les travaux présentés dans ce mémoire proposent des premières réponses à ces questions, via l'utilisation de techniques de commande avancées comme la commande optimale ou la commande robuste. Des outils originaux de modélisation, basés sur les systèmes d'ordre non entier seront également présentés pour la modélisation de dispositifs diffusifs (machines électriques, générateurs électrochimiques) ou modélisés par des équations aux dérivées partielles.

Full text
Abstract:
Cette thèse porte sur deux aspects de la dépendance entre actifs financiers. La première partie concerne la dépendance entre vecteurs aléatoires. Le premier chapitre consiste en une comparaison d'algorithmes calculant l'application de transport optimal pour le coût quadratique entre deux probabilités sur R^n, éventuellement continues. Ces algorithmes permettent de calculer des couplages ayant une propriété de dépendance extrême, dits couplage de corrélation maximale, qui apparaissent naturellement dans la définition de mesures de risque multivariées. Le second chapitre propose une définition de la dépendance extrême entre vecteurs aléatoires s'appuyant sur la notion de covariogramme ; les couplages extrêmes sont caractérisés comme des couplages de corrélation maximale à modification linéaire d'une des marginales multivariées près. Une méthode numérique permettant de calculer ces couplages est fournie, et des applications au stress-test de dépendance pour l'allocation de portefeuille et la valorisation d'options européennes sur plusieurs sous-jacents sont détaillées. La dernière partie décrit la dépendance spatiale entre deux diffusions markoviennes, couplées à l'aide d'une fonction de corrélation dépendant de l'état des deux diffusions. Une EDP de Kolmogorov forward intégrée fait le lien entre la famille de copules spatiales de la diffusion et la fonction de corrélation. On étudie ensuite le problème de la dépendance spatiale atteignable par deux mouvements Browniens, et nos résultats montrent que certaines copules classiques ne permettent pas de décrire la dépendance stationnaire entre des mouvements Browniens couplés.

Optimization techniques have played a vital role in improving the performance (i.e., input speed and accuracy) of soft keyboards. This chapter introduces the challenges, methodologies, and results of keyboard performance optimization. Leveraging the robust human motor control phenomena manifested in text entry, we used the Metropolis random walk algorithm, and Pareto multi-objective optimization method to optimize the keyboard layout and a soft keyboard decoder. The optimization led to layouts that shorten finger travel distance and improve the input speed as well as accuracy over the Qwerty layout, and a soft keyboard decoder with improved correction and completion ability.

Universal newborn hearing screening has meant that babies with significant congenital hearing impairment can be identified soon after birth and management instituted to ameliorate resultant problems, that is, minimize disability and handicap and optimize life chances. Evidence for the value of school entry screening is lacking and there is some evidence it is neither effective nor cost-effective. Further research is needed on this. Otitis media with effusion can cause significant long-lasting effects and may need surgical intervention or the provision of hearing aids. Parents and professionals should be aware of the symptoms that are indicative of possible hearing loss. Parents’ concerns should always be taken seriously.

Abstract:
Decision making is the process by which alternatives are deliberated and chosen based on the values and goals of the decision maker. In this chapter, we describe recent progress in understanding how living organisms make decisions and the implications for engineering artificial systems with decision-making capabilities. Nature appears to re-use design principles for decision making across a hierarchy of organizational levels, from cells to organisms to entire populations. One common principle is that decision formation is realized by accumulating sensory evidence up to a threshold, approximating the optimal statistical technique of sequential analysis. Sequential analysis has applications spanning from cryptography to clinical drug testing. Artificial perception based on sequential analysis has advanced robot capabilities, enabling robust sensing under uncertainty. Future applications could lead to individual robots, or artificial swarms, that perceive and interact with complex environments with an ease and robustness now achievable only by living organisms.

Abstract:
Since the mid-twentieth century, the DSM has guided psychiatrists in categorizing disorders. Revisions have taken years, with work groups considering changes to the entire manual. A more timely and efficient approach to updating the DSM would involve continuous improvement of particular diagnostic categories, when and if supported by advances in the field. The aim is to avoid the delays in the incorporation of new knowledge that are inherent in updating at intervals of a decade or more. The American Psychiatric Association has therefore established a structure by which evidence-based proposals for changes to the DSM can be considered and adopted on an ongoing basis. This chapter describes how proposals will be considered and the standards to be applied to proposed modifications. Challenges include calibrating optimal rigor of the review process, pruning diagnoses that lack validity or clinical utility, and subjecting the process itself to iterative improvement.

Abstract:
This chapter begins with a discussion of the architecture of international law. The economic analysis of international law, like virtually all writing on international law, tends to focus on the state as the key unit. As states pursue their individual goals they will inevitably create externalities that affect other states, creating a gap between what is optimal for an individual state and what is globally efficient. The business of international cooperation and international law can be conceived of as an attempt to close that gap. Central to the international legal system are formally binding agreements among states. States enter into what amounts to contracts in an effort to address externalities created by their actions. The remainder of the chapter deals with economic issues in international law (trade, environment, human rights and humanitarian law, use of force, and investment).

Abstract:
Epilepsy is most prevalent at each end of the age spectrum—the very young and the very old. Up to 1 per cent of the childhood population will have active epilepsy at any time. Of these 60–70 per cent will be controlled on medication or enter into spontaneous remission, however the remainder will continue to have seizures despite the range of treatment available. There will be associated comorbidity of learning and behaviour difficulties in a significant proportion, and these may take precedence in management over the seizures themselves. Careful evaluation of each individual child with regard to the possible diagnosis and associated comorbidities is required in all children presenting with recurrent paroxysmal episodes in order to optimize management.

Abstract:
Perceived objects are unitary entities that enter our consciousness as organized wholes distinct from other entities and from empty parts of the environment, that are amenable to bodily interactions, and that possess several features such as a three-dimensional structure, a location in space, a colour, a texture, a weight, a degree of rigidity, an odour, and so on. In this chapter, we will discuss perceptual processes responsible for forming such units within and between sensory channels, typically for the purpose of recognition. Our discussion of multisensory interactions in object perception will provide a useful domain for illustrating the key notion of optimal multisensory integration and for introducing Bayesian models of perception. These models provide important novel ways of addressing classical problems in the philosophy of perception, in influential historical approaches such as the Gestalt theory of perception, and in applications to rehabilitation based on sensory substitution.

Abstract:
There is growing data that dietary factors have profound effects on inflammation, the gut microbiome, intestinal permeability, and the blood–brain barrier; all of which impact brain health and psychological well-being. The Western diet in particular is deleterious for both physical and cognitive/emotional health. This occurs primarily by causing inflammation in the gut and an activation of the immune system along with causing impairment in the integrity of the gut lining. This allows many reactive molecules to enter the general circulation and even cross the blood–brain barrier. Recent research advances elucidate that understanding the harmful physiological effects of certain dietary behaviors is as important as knowing the role of critical nutrients for optimal brain health. This chapter reviews current knowledge regarding diet and nutrition in the context of psychiatric disorders and brain health. Information is reviewed regarding the most appropriate dietary and nutrition approaches to support optimum brain health.

Abstract:
AbstractIn this paper, an adversarial encryption algorithm based on generating chaotic sequence by GAN is proposed. Starting from the poor leakage resistance of the basic adversarial encryption communication model based on GAN, the network structure was improved. Secondly, this paper used the generated adversarial network to generate chaotic-like sequences as the key K and entered the improved adversarial encryption model. The addition of the chaotic model further improved the security of the key. In the subsequent training process, the encryption and decryption party and the attacker confront each other and optimize, and then obtain a more secure encryption model. Finally, this paper analyzes the security of the proposed encryption scheme through the key and overall model security. After subsequent experimental tests, this encryption method can eliminate the chaotic periodicity to a certain extent and the model’s anti-attack ability has also been greatly improved. After leaking part of the key to the attacker, the secure communication can still be maintained.

The increase in industrial data combined with big data technologies triggers a wide range of new technical applications with new forms of value propositions that shift the logic of how business is done. To capture these new types of value, data-driven solutions for the industry will require new business models. The design of data-driven AI-based business models needs to incorporate various perspectives ranging from customer and user needs and their willingness to pay for new data-driven solutions to data access and the optimal use of technologies, while taking into account the currently established relationships with customers and partners. Successful data-driven business models are often based on strategic partnerships, with two or more players establishing the basis for sustainable win-win situations through transparent resource-, investment-, risk-, data- and value-sharing. This chapter will explore the different data-driven business approaches and highlight in this context the importance of functioning ecosystems on the various levels. The chapter will conclude with an introduction to the data-driven innovation framework, a proven methodology to guide the systematic investigation of data-driven business opportunities while incorporating the dynamics of the underlying ecosystems.

Abstract:
AbstractSurging populations, coupled with the ever-increasing demand for sustenance, have led to the generation of behemoth proportions of wastes throughout the globe. The processing of such a considerable amount of waste has raised concerns for environmental planners, policymakers, and researchers in regard to maintaining sustainability. Biodegradable waste is a part of the total waste stream. Consideration should be given to the importance of making better use of biodegradable waste. The technology that is adopted for the management of biodegradable waste should be ecologically sustainable and cost-effective, as well as beneficial to social well-being. The most efficient way of managing biodegradable waste must include different methods for the optimal utilisation of such waste, ranging from the small scale (single household) to the very large scale (entire city). Amid all the other waste processing technologies, composting stands out as a most potent option because of its ability to maintain and restore soil fertility, along with the transformation of waste into a resource. Composting is one of the few technologies which has a benefit–cost ratio higher than 1 at all scales of operation. This chapter analyses the most significant aspects of the composting process, including the recent developments and dynamics involved in it. The chapter discusses various aspects of composting via analysis of the integrated waste management system and composting-related projects implemented at the community level in the Indian context. Finally, the chapter presents policies and the efforts put in place by the Government of India with the aim of encouraging composting practice and related activities.

AbstractThis chapter proposes a selective flip-flop optimization method (Golanbari et al., IEEE Trans Very Large Scale Integr VLSI Syst 39(7):1484–1497, 2020; Golanbari et al., Aging guardband reduction through selective flip-flop optimization. In: IEEE European Test Symposium (ETS) (2015)), in which the timing and reliability of the VLSI circuits are improved by optimizing the timing-critical components under severe impact of runtime variations. As flip-flops are vulnerable to aging and supply voltage fluctuation, it is necessary to address these reliability issues in order to improve the overall system lifetime. In the proposed method, we first extend the standard cell libraries by adding optimized versions of the flip-flops designed for better resiliency against severe Bias Temperature Instability (BTI) impact and/or supply voltage fluctuation. Then, we optimize the VLSI circuit by replacing the aging-critical and voltage-drop critical flip-flops of the circuit with optimized versions to improve the timing and reliability of the entire circuit in a cost-effective way. Simulation results show that incorporating the optimized flip-flops in a processor can prolong the circuit lifetime by 36.9%, which translates into better reliability.This chapter is organized as follows. Section 1 introduces wide-voltage operation reliability issues and motivates the proposed selective flip-flop optimization approach. The impacts of runtime variations on flip-flops are explained in Sect. 2. Consequently, Sect. 3 presents cell-level optimization of the flip-flops. The proposed selective flip-flop optimization methodology is described in Sect. 4, and optimization results are discussed in Sect. 5. Finally, Sect. 7 concludes the chapter.

Abstract:
This book chapter proposes use of Ant Colony Optimization (ACO), a novel computational intelligence technique for balancing loads of virtual machine in cloud computing. Computational intelligence(CI), includes study of designing bio-inspired artificial agents for finding out probable optimal solution. So the central goal of CI can be said as, basic understanding of the principal, which helps to mimic intelligent behavior from the nature for artifact systems. Basic strands of ACO is to design an intelligent multi-agent systems imputed by the collective behavior of ants. From the perspective of operation research, it's a meta-heuristic. Cloud computing is a one of the emerging technology. It's enables applications to run on virtualized resources over the distributed environment. Despite these still some problems need to be take care, which includes load balancing. The proposed algorithm tries to balance loads and optimize the response time by distributing dynamic workload in to the entire system evenly.

Abstract:
Abstract This paper describes a methodology for determining input setpoints in engineering systems to simultaneously optimize multiple conflicting output responses. Orthogonal arrays are used to design experiments and capture experimental data. A nonlinear regression model using the mean value of each output response is obtained using MARS (Multivariate Adaptive Regression Splines). A multiobjective optimization method based on adaptive simulated annealing is then employed for generating global Pareto-optimal setpoints. Different conflicting objectives are traded-off against each other on the Pareto-optimal frontier to obtain the best setpoints. Two classes of experiments are discussed; one in which there are only two objectives and it is possible to visualize the entire Pareto-optimal curve and the other when the number of objectives are greater than three when it is no longer possible to visualize the entire Pareto-optimal hypersurface. The approach is also extended to include nonlinear models of signal-to-noise ratios that provide setpoints that are robust with respect to noise in the Taguchi sense. Several setpoint determination problems from the xerographic domain are presented to illustrate the overall approach.

Abstract:
Although much work has been done to optimize individual components of electrolyzers and fuel cells, very little has been done to simulate and optimize the entire system. A thorough paper review has been conducted to increase the accuracy of the PEM electrolyzer model and simulation discussed in this study. Data on optimal thicknesses and electrical properties of various electrolyzer elements was collected from various sources and collated. The simulation was then implemented to optimize the current collector rib dimensions for maximum performance and efficiency over a variety of temperatures. This paper shows higher temperatures significantly improve the efficiency of the cell while also increasing the optimal rib width dimensions. The increased efficiency is most likely due to the excess heat contributing towards the threshold energy required for the electrolysis while the varying resistances of the proton exchange membrane, with respect to temperature, can explain the increased rib width.

Abstract:
«The electronic magazine with rating system of an estimation of individual and collective work of students» (EM) is developed in document Microsoft Excel with use of macros. EM allows to automate all the calculated operations connected with estimation of amount scored by students in each form of the current control. EM provides automatic calculation of rating of the student with reflection of a maximum quantity of the points received in given educational group. The rating equal to “1” is assigned to the student who has got a maximum quantity of points for the certain date. For the other students the share of their points in this maximum size is indicated. The choice of an estimation is made in an alphabetic format according to requirements of the European translation system of test units for the international recognition of results of educational outcomes (ECTS - European Credit Transfer System), by use of a corresponding scale of an estimation. The list of students is placed on the first page of magazine and automatically displayed on all subsequent pages. For each page of magazine the optimal size of document printing is set with automatic enter of current date and time. Owing to accounting rate of complexity of task EM is the universal technical tool which can be used for any subject matter.
