The Application of a Pluralist Approach of Global Administrative Law on the Governance of Doping in Sport

Plusieurs problèmes liés à l'utilisation de substances et méthodes interdites de dopage dans les sports posent de grands défis à la gouvernance antidopage. Afin de lutter contre le dopage, certains pays ont mis en oeuvre des cadres juridiques basés exclusivement sur le droit pénal tandis que d'autres pays ont plutôt misé sur des mécanismes et organismes spécialisés trouvant fondement en droit privé ou sur un régime hybride de droit public et privé. Ces différentes approches réglementaires ont pour conséquence de faire en sorte qu’il est très difficile de lutter efficacement contre le dopage dans les sports, notamment parce que leur exécution requiert un degré de collaboration internationale et une participation concertée des autorités publiques qui est difficile à mettre en place. À l’heure actuelle, on peut par exemple observer que les États n’arrivent pas à contrer efficacement la participation des syndicats et organisations transnationales liés au crime organisé dans le marché du dopage, ni à éliminer des substances et méthodes de dopage interdites par la réglementation. Par ailleurs, la gouvernance antidopage basée sur les règles prescrites par l’Agence mondiale antidopage prévoit des règles et des normes distinctes de dopage distinguant entre deux catégories de personnes, les athlètes et les autres, plaçant ainsi les premiers dans une position désavantageuse. Par exemple, le standard de responsabilité stricte sans faute ou négligence imposé aux athlètes exige moins que la preuve hors de tout doute raisonnable et permet l'utilisation de preuves circonstancielles pour établir la violation des règles antidopages. S'appliquant pour prouver le dopage, ce standard mine le principe de la présomption d'innocence et le principe suivant lequel une personne ne devrait pas se voir imposer une peine sans loi. D’ailleurs, le nouveau Code de 2015 de l’Agence attribuera aux organisations nationales antidopage (ONADs) des pouvoirs d'enquête et de collecte de renseignements et ajoutera de nouvelles catégories de dopage non-analytiques, réduisant encore plus les droits des athlètes. Dans cette thèse, nous discutons plus particulièrement du régime réglementaire de l’Agence et fondé sur le droit privé parce qu’il ne parvient pas à répondre aux besoins actuels de gouvernance mondiale antidopage. Nous préconisons donc l’adoption d’une nouvelle approche de gouvernance antidopage où la nature publique et pénale mondiale du dopage est clairement reconnue. Cette reconnaissance combiné avec un modèle de gouvernance adapté basé sur une approche pluraliste du droit administratif global produira une réglementation et une administration antidopage mieux acceptée chez les athlètes et plus efficace sur le plan des résultats. Le nouveau modèle de gouvernance que nous proposons nécessitera toutefois que tous les acteurs étatiques et non-étatiques ajustent leur cadre de gouvernance en tenant compte de cette nouvelle approche, et ce, afin de confronter les défis actuels et de régler de manière plus satisfaisante les problèmes liés à la gouvernance mondiale du dopage dans les sports.

La notion de bonne foi dans les immunités législatives au Québec : entre imprécision et redondance

Les immunités législatives pour bonne foi sont une composante importante des règles spécifiques s’appliquant à la responsabilité civile des administrations publiques. Apparues dans les années 1940 au Québec, elles visent à insuffler à la responsabilité civile les considérations propres à l’action étatique (difficulté des tâches, pouvoir discrétionnaire, liberté d’action, etc.). Or, la notion principale de ces immunités, la bonne foi, est d’une nature fragile. Tiraillée entre une vision subjective et objective, elle souffre de nombreuses lacunes. Originalement fondée sur l’évaluation de l’état d’esprit d’une personne, la bonne foi reproduit dorénavant le concept de faute lourde présent en responsabilité civile. Il en résulte un système qui crée de la confusion sur l’état mental nécessaire pour entrainer la responsabilité d’une administration publique. Au surplus, le régime de la bonne foi est variable et change selon les fonctions exercées par les administrations publiques. Ces attributs mettent en exergue le peu d’utilité de cette notion : la bonne foi dédouble plusieurs éléments déjà présents en responsabilité civile québécoise et partant de là, affaiblit sa place comme règle particulière applicable aux administrations publiques. Bref, par son caractère adaptable, la bonne foi est un calque de la responsabilité civile québécoise et son faible apport embrouille le régime de cette dernière.

Data Security in Fault Tolerant Hard Real Time Systems- Use of Time Dependant Multiple Random Cipher Code

The present research problem is to study the existing encryption methods and to develop a new technique which is performance wise superior to other existing techniques and at the same time can be very well incorporated in the communication channels of Fault Tolerant Hard Real time systems along with existing Error Checking / Error Correcting codes, so that the intention of eaves dropping can be defeated. There are many encryption methods available now. Each method has got it's own merits and demerits. Similarly, many crypt analysis techniques which adversaries use are also available.

Electrical conductivity and thermally stimulated current in the paraelectric phase of (NH4)2SO4

Anomalous variations of d.c. electrical conductivity with temperature are observed in ammonium sulphate single crystals, suggesting a possible phase transition at 150°C. Measurements of thermally stimulated current also support these results. The mechanism of electrical conduction is explained on the basis of studies made on doped and quenched crystals.

Chaotic Dynamics of Semiconductor Laser with Current Modulation and optoelectronic feedback

Chaotic dynamics of directly modulated semiconductor lasers have been studied extensively over the last two decades because of their application in secure optical communication. However, chaos is generally suppressed in such systems when the nonlinear gain reduction factor is above 0.01 which is very much smaller than the reported values in semiconductors like InGaAsP. In this paper we show that by giving an optoelectronic feedback with appropriate delay one can increase the range of the values of the gain reduction factor for which chaos can be observed. Numerical studies show that negative feedback is more efficient in producing chaotic dynamics.

Consequence modelling,vulnerability assessment and fuzzy fault tree analysis of hazardous storages in an industrial area

The hazards associated with major accident hazard (MAH) industries are fire, explosion and toxic gas releases. Of these, toxic gas release is the worst as it has the potential to cause extensive fatalities. Qualitative and quantitative hazard analyses are essential for the identitication and quantification of the hazards associated with chemical industries. This research work presents the results of a consequence analysis carried out to assess the damage potential of the hazardous material storages in an industrial area of central Kerala, India. A survey carried out in the major accident hazard (MAH) units in the industrial belt revealed that the major hazardous chemicals stored by the various industrial units are ammonia, chlorine, benzene, naphtha, cyclohexane, cyclohexanone and LPG. The damage potential of the above chemicals is assessed using consequence modelling. Modelling of pool fires for naphtha, cyclohexane, cyclohexanone, benzene and ammonia are carried out using TNO model. Vapor cloud explosion (VCE) modelling of LPG, cyclohexane and benzene are carried out using TNT equivalent model. Boiling liquid expanding vapor explosion (BLEVE) modelling of LPG is also carried out. Dispersion modelling of toxic chemicals like chlorine, ammonia and benzene is carried out using the ALOHA air quality model. Threat zones for different hazardous storages are estimated based on the consequence modelling. The distance covered by the threat zone was found to be maximum for chlorine release from a chlor-alkali industry located in the area. The results of consequence modelling are useful for the estimation of individual risk and societal risk in the above industrial area.Vulnerability assessment is carried out using probit functions for toxic, thermal and pressure loads. Individual and societal risks are also estimated at different locations. Mapping of threat zones due to different incident outcome cases from different MAH industries is done with the help of Are GIS.Fault Tree Analysis (FTA) is an established technique for hazard evaluation. This technique has the advantage of being both qualitative and quantitative, if the probabilities and frequencies of the basic events are known. However it is often difficult to estimate precisely the failure probability of the components due to insufficient data or vague characteristics of the basic event. It has been reported that availability of the failure probability data pertaining to local conditions is surprisingly limited in India. This thesis outlines the generation of failure probability values of the basic events that lead to the release of chlorine from the storage and filling facility of a major chlor-alkali industry located in the area using expert elicitation and proven fuzzy logic. Sensitivity analysis has been done to evaluate the percentage contribution of each basic event that could lead to chlorine release. Two dimensional fuzzy fault tree analysis (TDFFTA) has been proposed for balancing the hesitation factor invo1ved in expert elicitation .

Current-density-functional approach to large quantum dots in intense magnetic fields

Within current-density-functional theory, we have studied a quantum dot made of 210 electrons confined in a disk geometry. The ground state of this large dot exhibits some features as a function of the magnetic field (Beta) that can be attributed in a clear way to the formation of compressible and incompressible states of the system. The orbital and spin angular momenta, the total energy, ionization and electron chemical potentials of the ground state, as well as the frequencies of far-infrared edge modes are calculated as a function of Beta, and compared with available experimental and theoretical results.

Water characteristics and current structure of the intermediate waters in the arabian sea

At intermediate depths of the Arabian Sea, the circulation and characteristics of water are more influenced by the high saline waters from the north and low saline waters from the south of equator. The interaction of these waters which greatly differ in characteristics is less understood compared to that at the upper layers. An understanding of the nature of the intermediate waters is of vital importance not only because of the unusual characteristics of the waters but also due to the influx of the different water masses from the neighbouring Red Sea and Persian Gulf. Hence, in the present investigation, it is proposed to study the water characteristics and current structure of the intermediate waters in the Arabian Sea through the distribution of the water properties on the isanosteric surfaces of 100, 80, 60 and 4O—cl/t, vertical sections, and scatter diagrams An attempt is also made to present the potential vorticity between different steric levels to understand the circulation and mixing processes. Data collected during and subsequent to International Indian Ocean Expedition (IIOE) are used for this study. The thesis has been divided into six chapters with further sub divisions

Self-consistent theory of current and voltage noise in multimode ballistic conductors

Electron transport in a self-consistent potential along a ballistic two-terminal conductor has been investigated. We have derived general formulas which describe the nonlinear current-voltage characteristics, differential conductance, and low-frequency current and voltage noise assuming an arbitrary distribution function and correlation properties of injected electrons. The analytical results have been obtained for a wide range of biases: from equilibrium to high values beyond the linear-response regime. The particular case of a three-dimensional Fermi-Dirac injection has been analyzed. We show that the Coulomb correlations are manifested in the negative excess voltage noise, i.e., the voltage fluctuations under high-field transport conditions can be less than in equilibrium.

Studies On Preparation And Characterization Of Hts Current Leads Using Multifilamentary Ag And Ag-Alloy Sheathed (Bi,Pb)-2223 Superconducting Tapes

The application vistas of superconductors have widened very much since the discovery of high TC superconductors (HTS) as many of the applications can be realised at 77 K rather than going down to 4.2 K, the liquid He temperature. One such application is the HTS current lead which is used to connect a superconducting system with a room temperature power source. Minimising heat leak to the cryogenic environment is the main advantage of introducing current leads into superconducting systems. The properties of HTSS likes zero resistance (avoiding joule heating) and very low thermal conductivity (minimized conductive heat transfer) make them ideal candidates to be used as current leads. There are two forms of HTS current leads. (i) bulk form (tube or rod) prepared either from YBCO or BSCCO and (ii) tape form prepared from Bi-2223 multifilamentary tapes. The tape form of current leads has many advantages with respect to the mechanical and thermal stability related criteria. Crucial information on various aspects of HTS current lead development are not available in the literature as those are kept proprietary by various companies around the world. The present work has been undertaken to tailor the properties of multifilamentary tapes for the current lead application and to optimise the processing parameters of the same for enhanced critical current density and field tolerance. Also it is the aim of the present investigation is to prepare prototype current leads engineered for operation in conduction cooled mode and test them for operational stability

Fault Tolerant Error Coding and Detection using Reversible Gates

In recent years, reversible logic has emerged as one of the most important approaches for power optimization with its application in low power CMOS, quantum computing and nanotechnology. Low power circuits implemented using reversible logic that provides single error correction – double error detection (SEC-DED) is proposed in this paper. The design is done using a new 4 x 4 reversible gate called ‘HCG’ for implementing hamming error coding and detection circuits. A parity preserving HCG (PPHCG) that preserves the input parity at the output bits is used for achieving fault tolerance for the hamming error coding and detection circuits.
