Le système d’éducation québécois, comme la société qui l’entoure, se fragmente : d’abord, en fonction des facteurs sociaux traditionnels — notamment, le revenu et l’éducation des parents —, ensuite, en fonction de la multiplication de modèles socioculturels. Dans le champ de l’enseignement primaire et secondaire, la première fragmentation s’exprime par la montée de l’enseignement privé, notamment dans les centres urbains; la seconde fragmentation se manifeste, au sein du réseau public, par la multiplication et la variété des projets particuliers, conçus pour retenir des élèves de milieux favorisés, mais aussi pour permettre à des groupes sociaux de transmettre à leurs enfants une éducation distinctive. Ce texte analyse la manifestation de cette double fragmentation dans le champ éducatif et la contextualise dans le cadre de grands changements sociétaux. Nous soutenons qu’ainsi mis sur les rails de la concurrence, le système scolaire québécois est de plus en plus stratifié ou qu’il a plusieurs vitesses. Nous explorons quelques politiques publiques qui permettraient la sortie d’une situation difficile à dépasser.

Texto completo da fonteResumo:
The paper analyses the problems of concurrence of the conditions under which criminal proceedings are permissible. In Polish legal studies, there are different takes on these problems. The author introduces a division into concurrence of formal conditions of the same kind (Article 17(1)(5) and (7) to (10) of the Code of Criminal Procedure), concurrence of substantive conditions of the same kind (Article 17(1)(1) to (4) CCP) and concurrence of conditions of different kinds, after which she tries to develop practical guidance to help either choose one of the concurrent conditions under proceedings are permissible as the grounds for refusal to initiate criminal proceedings or for discontinuance of such proceedings or – alternatively – for accumulation of such conditions. The author of the article provides arguments for and against both cumulative and eliminative concurrence of conditions under which proceedings are permissible; basically she is inclined to treat them as cumulative.

Texto completo da fonteResumo:
Mis en place le 25 mai 2018, le RGPD est l’un des rares textes européens dont on parle encore près de 3 ans après son adoption : c’est assez rare pour être souligné. Son champ d’application remet les acteurs européens à égalité de concurrence avec les acteurs mondiaux et permet à l'Europe de prendre toute sa place dans l’économie numérique globale. De nombreux pays ont ainsi mis à jour leur réglementation pour se rapprocher des standards européens. À l’échelle européenne, la coopération est réelle et une véritable doctrine européenne se construit. Enfin, en France, les chiffres montrent que lorsqu’on explique mieux aux citoyens leurs droits, ceux-ci s’en saisissent massivement. Le contexte politique et juridique de 2020, exceptionnel à plusieurs égards, offre un alignement inédit des intérêts entre notre régulation en matière de protection des données et notre politique industrielle, qu’il faut mettre au service d’une stratégie ambitieuse en matière de souveraineté numérique.

Résumé S’appuyant sur l’étude des discours de réception des romanciers admis au sein de l’Académie française dans la seconde moitié du XIX e siècle jusqu’à 1914 et des réponses des directeurs académiques qui Jes accueillent, on veut discerner comment l’institution s’est pliée à la progression historique du roman attestée par son succès auprès du lectorat, tout en tentant d’infléchir son devenir. On constate une relecture du passé récent, l’Académie faisant notamment amende honorable de son refus envers Balzac, mais persistant à exclure les réalistes contemporains. Encore convaincue de la légèreté du genre, de son inaptitude à égaler philosophie, histoire, poésie et comédie, et surtout de sa nocivité morale, les Immortels préfèrent élire des romanciers «honnêtes» — Sandeau, Feuillet, Dumas fils, Cherbuliez - dans l’espoir de fixer des normes sociales à ce genre ascendant. Indignés du développement de l’école naturaliste, ils la combattent en appelant parmi eux les pontifes de la littérature idéaliste de la fin du siècle — Loti, Bourget, France, Barrés. En 1900, le roman siège à égalité avec les autres genres sous la Coupole, mais la concurrence de l’Académie Goncourt stigmatise le retard pris par l’institution.

La littérature sur la politique européenne de concurrence présente un hiatus. À ses débuts, elle aurait d’abord été marquée par une approche très légaliste de la régulation des luttes économiques, avant une évolution brutale vers une analyse plus économique au tournant des années 2000. Cet article entend proposer un trait d’union entre ces deux épisodes en étudiant la trajectoire heurtée d’économicisation de l’administration européenne de la concurrence et ses conditions de possibilité.

We discuss a family of W-class states describing three-qubit systems. For such systems, we analyze the relations between the entanglement measures and the nonlocality parameter for a two-mode mixed state related to the two-qubit subsystem. We find the conditions determining the boundary values of the negativity, parameterized by concurrence, for violating the Bell-CHSH inequality. Additionally, we derive the value ranges of the mixedness measure, parameterized by concurrence and negativity for the qubit–qubit mixed state, guaranteeing the violation and non-violation of the Bell-CHSH inequality.

Dans cet article, nous analysons, en première instance, le concept « d’égalité des conditions » de Tocqueville en montrant que ce concept peut être divisé en trois égalités distinctes dans son œuvre : l’égalité de considération, l’égalité des chances et l’égalité en droits politiques. En analysant le cas des sociétés américaine et française, nous conceptualisons l’égalité de considération comme une égalité matricielle et « imaginaire » des sociétés démocratiques modernes, qui conditionne les deux autres égalités. Puis, nous montrons comment le concept « d’égalité des conditions » de Tocqueville est en fait un véritable « imaginaire social » qui institue et construit les sociétés démocratiques de notre temps.

Rooftop PV-BESS installations often lose profitability despite policy support to accelerate capacity growth. This paper performs techno-economic analysis to assess the effect of heterogeneity in real-world conditions on the economic viability of residential rooftop PV-BESSs. The stochastic nature of generation and consumption is modeled as multiple deterministic scenarios that vary in the capacity rating of the PV system, climatic conditions (insolation and temperature), self-consumption ratio (SCR), generation–demand concurrence, and the presence/absence of capacity and storage subsidies. The results indicate that PV-BESSs are mostly profitable when operating at a capacity factor ≥ 18%. Furthermore, higher daytime electricity consumption enables greater savings with smaller storage capacities, thereby facilitating cost-effective installations at capacity factors ≥ 8%. However, low-yielding PV-BESSs and prosumers exhibiting low generation–demand concurrence require suitable subsidy allocations to become profitable.

Texto completo da fonteResumo:
En tant que concept économique, la distorsion de concurrence désigne l'effet de l'intervention de l'État dans l'économie. Si cette notion a été formellement transposée en droit de l'Union européenne, elle est néanmoins perçue comme imprécise sur le plan juridique. En effet, son sens demeure flou et les multiples acceptions qui en découlent rendent sa conceptualisation délicate. Cependant, malgré cette diversité interprétative, il est envisageable de concevoir la distorsion de concurrence comme un concept juridique opérationnel. Pour y parvenir, il était nécessaire d'élaborer une théorie générale de la notion de distorsion de concurrence. Ainsi, cette thèse ambitionne d'identifier la signification et la portée juridiques de la distorsion de concurrence telle qu'elle se manifeste en droit positif, afin d'en proposer une définition unitaire. Une fois sa conceptualisation effectuée, il est alors possible de déterminer le régime juridique applicable à la distorsion de concurrence et de préciser les conditions dans lesquelles celle-ci doit être sanctionnée ou, au contraire, autoriséeAs an economic concept, the notion of distortion of competition refers to the effect of State intervention in the economy. Although this notion has been formally transposed into European Union law, it is nevertheless perceived as ill-defined in legal terms. Indeed, what it designates remains unclear, and the multiplicity of meanings that can be construed from this expression makes its conceptualization difficult. However, despite the diversity of potential interpretations, it is possible to conceive the notion of distortion of competition as an operational legal concept. To reach that point, it was necessary to develop a general theory of the notion of distortion of competition. Thus, this doctoral dissertation aims to identify the legal meaning and scope of the notion of distortion of competition as it manifests itself in positive law, in order to suggest a unitary definition of the notion. Once conceptualized, it is then possible to determine the legal regime applicable to the notion of distortion of competition, and to specify the conditions under which it should be banned or, on the contrary, permitted

Blanchard, Marie. "L' égalité de traitement entre entreprises en droit communautaire de la concurrence". Paris 2, 2004. http://www.theses.fr/2004PA020090.
Texto completo da fonteResumo:
L'objectif d'une concurrence non faussée, posé par le droit communautaire de la concurrence, implique le respect de l'égalité de traitement entre les entreprises, conçue comme une égalité des chances. Cette égalité n'est cependant qu'un moyen pour atteindre les missions fixées à l'article 2 du traité CE. La commission dispose ainsi d'un pouvoir discrétionnaire pour apprécier les circonstances de la qualification et de la sanction d'une infrastructure aux règles de concurrence : elle n'est donc pas obligée d'appliquer des critères identiques au traitement des entreprises. Mais ces mesures de doivent pas être discriminatoires, car l'interdiction de discrimination est un principe général du droit communautaire. Il implique en effet que des situations comparables doivent être traitées de manière identique et que des situations non comparables doivent être traitées de manière différente, sauf s'il existe une justification objective. Mais ce principe est peu opératoire en droit communautaire de la concurrence, précisément parce que la commission dispose d'un large pouvoir d'appréciation. Par conséquent, il est difficile d'apprécier la teneur discriminatoire d'une règle de concurrence ou se son application. En revanche, on pourrait considérer que la mesure prise par les autorités communautaires n'est pas discriminatoire si, lors de son adoption ou de sa mise en œuvre, toutes les entreprises ont pu également exprimer leurs intérêts. Cette égalité de traitement entre les entreprises dans les procédures entourant l'élaboration et l'application des règles de concurrence pourrait être désignée sous le terme d'égalité procédurale.

Bortoluzzi, Stéphane. "L'équilibre juridique de la concurrence : aspects de droit privé". Paris 1, 1998. http://www.theses.fr/1998PA010321.
Texto completo da fonteResumo:
La dualité du droit privé conduit à soumettre les relations économiques semblables, voire concurrentes, à des régimes différents, selon la nature intrinsèque des opérations réalisées et la qualité des personnes concernées. Dans ses aspects de droit privé, la question de l'équilibre juridique de la concurrence se pose principalement dans le traitement du paracommercialisme. L'activité est paracommerciale chaque fois qu'elle se développe au moyen d'actes de commerce, sans conférer pour autant à son auteur, qui continue de bénéficier des avantages spécifiques attachés à son statut, la qualité de commerçant. Un véritable droit des actes et des activités paracommerciales fut progressivement mis en place, avec ses spécificités juridiques et son lot de rattachement au droit commun par le jeu des théories classiques de l'accessoire civil et de la commercialité de fait. Dépourvu d'autonomie, ce statut catégoriel garantie un équilibre des forces dans la conquête de la clientèle et non une égalité des droits. La transposition du principe constitutionnel d’égalité devant la loi au domaine de la concurrence conduit vers une objectivisation des rapports et des notions juridiques. La législation économique doit régir non des personnes, a raison de leur qualité ou de la forme juridique d'exploitation, mais des opérations a raison de leur nature et de leur portée économique. Une théorie générale du droit des activités économiques et l'orientation vers un droit commun des groupements traduisent le mieux cette nouvelle approcheThe duality of private right leads to submit the similar economical relations even equal to different laws, according to the intrinsic nature of transactions realized and the quality of the people concerned. In those views of private right, the question of the juridical balance of competition essentially lays down upon the treatment of "paracommercialisme". The activity is said "paracommerciale" each time it develops with the help of commercial acts, without confering to its author, who is still making a profit of specific advantages attributed to his status, the quality of merchant. A real right of acts and "paracommerciales" activities has been progressively established with its legal specific characters and its common right of connection by the use of classical theories of the civil accessory and by the commerciality of fact. Destitute of independence, this specific status garanties a balance of the forces in the conquest of the customers, instead of an equality of the right. By the way of the transposition of the equal constitutionnal policy before the law in the field of competition, the economical legislation shall not rule people, because of their value or their juridical form, but operations, because of their nature and their economical scope. This new approach will be best expound by a new theory of right economical activities and by a trend towards a common right of societies

La présente thèse analyse l’incidence de la concurrence bancaire sur le coût et la qualité du crédit produit par les établissements de crédit. Plus précisément, les investigations empiriques menées dans le cadre de ce travail visent deux objectifs complémentaires. Tout d’abord, évaluer dans quelle mesure le degré de rivalité entre les banques influence la stratégie de tarification des banques et par conséquent le coût de financement des entreprises. Le second objectif de cette thèse consiste à étudier l’impact de la concurrence bancaire sur la manière dont les banques produisent de l’information privée sur leurs clients. Pour cela, nous procédons en deux étapes. En premier lieu, nous examinons l’influence du degré de rivalité entre les banques sur la nature des informations utilisées par les chargés d’affaires dans l’évaluation de la qualité des emprunteurs. En second lieu, nous vérifions l’implication de la concurrence bancaire dans la rupture des relations de long terme. Nous adoptons pour toutes les analyses conduites dans cette thèse une démarche permettant d’exploiter la complémentarité entre différents indicateurs de concurrence utilisés dans la littérature afin d’appréhender au mieux le niveau de rivalité entre les banques. Plusieurs résultats se dégagent des multiples analyses empiriques menées dans le cadre de ce travail. Premièrement, il ressort de nos investigations empiriques que le pouvoir de marché des institutions financières découle de deux sources distinctes: le poids de la banque dans la structure du marché local du crédit et le degré d’efficience de l’établissement de crédit. Par conséquent, l’incidence de la concurrence bancaire dépend de sa capacité à influencer la structure du marché local du crédit ou bien l’efficience des banques. De plus, nous montrons qu’au sein d’un marché bancaire concentré, l’existence de fortes rivalités entre les banques réduit le coût de financement des entreprises si ces dernières disposent d’une relation bancaire principale. Enfin, nous démontrons que la concurrence bancaire accroît la longévité des relations de clientèle et encourage les chargés d’affaires à produire plus d’informations privées sur les emprunteurs. Toutefois, il serait prudent au niveau des banques de suivre l’évolution des comportements des gestionnaires de relations bancaires en matière de production d’informations afin d’adapter les mesures incitatives à mettre en place pour garantir la pérennité de leurs comportementsThis thesis investigates the effect of banking competition on the cost and the quality of lending to firms by financial institutions.

We consider for all the analyzes conducted in this thesis an approach where the complementarity between different competition indicators used in the literature is exploited in order to better understand the level of rivalry among banks. Several results emerge from the multiple empirical analyzes conducted in this thesis. First, these show that the market power of financial institutions result from two separate sources: the weight of the bank in the local credit market structure, and the level of efficiency of the credit institution. Therefore, the impact of competition between banks depends on the ability of banking competition to influence the local market structure of credit or the efficiency of bank. Moreover, we show that within a concentrated banking market, the existence of strong rivalries between banks reduced the financing cost of firms that had a house bank. Finally, we demonstrate that banking competition increases the duration of bank-firm relationships and encourages loan officers to produce more private information about borrowers. However, it would be safe for banks to monitor the behavior of loan officers regarding their role on information production, in order to design incentives that ensure a sustained effort on their part

Texto completo da fonteResumo:
Dans le chapitre préliminaire sera présenté l'environnement juridique de la clause de non-concurrence, c'est-à-dire le paysage juridique allemand (la jurisprudence, le rôle de la doctrine et le contrat de travail) et les règles constitutionnelles et internationales. La partie 1 sera consacrée à l'intérêt légitime de l'employeur (droit allemand) ou de l'entreprise (droit français). Seront successivement abordées l'exigence et la notion d'intérêt légitime puis il sera opéré un rapprochement entre l'exigence d'un intérêt légitime et la vie du contrat de travail. La partie 2 étudiera la préservation de l'intérêt du débiteur de non-concurrence en s'intéressant tout d'abord à l'engagement du salarie (validité de l'engagement et limitation de la portée de l'engagement), puis en recherchant quelle est la compensation du respect de l'engagement de non-concurrence par le salarié.

Fontaine, Fabien. "Droit fiscal et concurrence". Thesis, Paris 2, 2014. http://www.theses.fr/2014PA020035.
Texto completo da fonteResumo:
Les rapports entre concurrence et droit fiscal, en tant que technique de mise en oeuvre du prélèvement fiscal, sont multiples et complexes. Il apparaît sans peine que la concurrence est affectée par le droit fiscal, dans la mesure où tant les dépenses fiscales que les normes fiscales peuvent dénaturer le rapport concurrentiel. En pratique un tel biais concurrentiel résulte de critères d’imposition ratione materiae ou personae qui décorrèlent la charge fiscale de l’avantage concurrentiel, lequel détermine à lui seul l’issue du jeu concurrentiel, et est réductible à l’avantage en valeur ajoutée. Dit de manière plus analytique, le droit fiscal est distorsif de concurrence lorsqu’il traite certains concurrents ou actes concurrents de manière différenciée, soit de jure, soit de facto, c’est-à-dire en fonction de leurs caractéristiques économiques, dans la mesure où une telle différenciation ne recoupe pas les différences de valeur ajoutée. Le jeu concurrentiel est par ailleurs un instrument du droit fiscal, qui définit un principe dit « de pleine concurrence » pour déterminer objectivement la base imposable d’échanges intragroupes. Ce principe, qui emporte des effets importants en droit commercial et en droit de la concurrence, permet en outre d’exposer empiriquement les distorsions de concurrence naissant d’une méconnaissance de la valeur ajoutée propre à chaque contribuable. Au final, la distorsion fiscale de concurrence apparaît bien comme une affaire de critère d’imposition ; cette dimension juridique pose nécessairement la question de la réception de cette distorsion par le droit positif. magistère de fait dessine ainsi une norme matérielle de concurrence qui affecte le droit fiscal. Ainsi, en droit interne, la teneur et la mise en oeuvre du principe d’égalité devant l’impôt repose de manière croissante sur des analyses concurrentielles spontanées du juge de l’impôt et du juge constitutionnel, dont la seule limite paraît être une approche abstraite de l’égalité et une grande latitude d’appréciation laissée par ces derniers au pouvoir fiscal. Ce rapport d’influence se double d’une véritable instrumentalisation du droit fiscal sur le terrain du droit économique, qui subordonne la fiscalité à sa propre finalité concurrentielle. En effet, le droit de l’Union européenne recourt de manière étendue et explicite à l’analyse concurrentielle dans son contrôle de conventionalité du droit fiscal, en s’opposant aux mesures fiscales internes susceptibles, par une atteinte à l’obligation de traitement national ou une concurrence fiscale déloyale, de mettre en échec l’intégration économique européenne. Appliquant au droit fiscal un prisme purement économique ne présentant que des égards très limités pour les objectifs et méthodes fiscales, le droit de l’Union européenne porte en germe la censure de toute politique fiscale, même indistinctement applicable, à raison de son objet mais plus encore de ses effets anticoncurrentiels. L’expression ultime de l’instrumentalisation du droit fiscal par la concurrence réside dans la jurisprudence qui commande l’imposition au seul regard des distorsions de concurrence naissant de son absence, faisant de la concurrence une source d’impositionThe relationship between competition and tax law, defined as a means of setting the tax burden for corporations, is far-reaching and complex. Competition is undoubtedly shaped by tax law, insofar as tax expenditures and regular tax provisions may adversely affect the outcome of competition on a given market. Specifically, competition may be distorted by tax criteria that unalign the tax burden from the competitive advantage which determines the market outcome, and which can be defined as the difference in added value between competitors. A more analytical expression of this would be that the criteria setting the tax burden distort competition - either de jure or de facto - when they provide for a specific tax treatment of certain competitors or competing operations. Furthermore, pursuant to the arm’s length principle, competition can be considered as an instrument for tax law, insofar as it is used as a tool for setting intragroup tax bases. The arm’s length principle, which falls under anticompetitive pricing rules, evidences the distorsion of competition that stems from disregarding taxpayers’ respective added values, thereby empirically confirming that tax capacity and added value should be aligned in order for tax law to be competition-neutral. Accordingly, tax distorsions of competition are a question of tax criteria; this legal dimension begs the question of whether such distorsions are characterized and regulated by statute and /or case law.A first observation would be that competition increasingly applies to tax law, marginally via competition law (which is a paradox), but more profoundly and widely as the defining influence behind a number of provisions and principles that govern tax law. That competition is accordingly instrumental for these norms would tend to make of competition a substantive norm for tax law. The French principle of equality before tax increasingly factors full-fledged competition analyses in the tax and constitutional courts’ appreciation of the competitive effects of tax provisions, but its scope is curtailed by an overly abstract conception of equality and, overall, a reluctance to challenge the legislator’s policy decisions. This influence, characterized in French law and conducive to tax being affected by the objective of free competition, also entails the instrumentalization of tax law in the field of economic law, which imposes on tax law its own competitive objectives. Indeed, EU law provides a wider and more explicit use of competition analysis in its appreciation of the lawfulness of tax law, by precluding provisions which, through discrimination on the grounds of nationality or unfair tax competition, conflict with the European economic integration. Specifically, tax provisions are tested for anticompetitive object and / or effects, with their fiscal objectives or methods being mostly disregarded in this respect, to the extent that anticompetitive effects can be viewed as the ultimate governing principle for tax law. This is conducive to the instrumentalization of tax law by competition, with far-reaching implications for tax policies and their underlying criteria. Ultimately, tax law is instrumentalized by competition in the case-law that warrants taxation on the grounds of the distortions of competition that would arise from its absence, effectively making competition a source of taxation

« Socle de la négociation commerciale », les Conditions de Vente occupent une place centrale dans la vie des affaires. Néanmoins, elles sont également sources de nombreuses interrogations, étant soumises aux influences conjuguées du droit des contrats et du droit de la concurrence. En effet, la liberté contractuelle ne s’oppose-t-elle pas à toute idée de transparence et d’équilibre entre les parties ? De même, permet-elle un contrôle effectif des comportements des opérateurs ? Réels, ces obstacles ne semblent pourtant pas insurmontables. Pour peu que l’on redéfinisse leurs rôles de manière claire, droit des contrats et droit de la concurrence sont conciliables. En imposant un point de départ fixe et transparent ainsi que des limites, le droit permettrait aux parties d’adapter leur convention à leurs besoins sans crainte d’abus. Formalisée, cette dernière permettrait également au législateur de s’assurer de l’absence de pratiques susceptibles de fausser irrémédiablement la concurrence“Root of any commercial negotiation”, Conditions of Sale (i. E. General conditions of sale, specific conditions of sale and retailing global contracts) are essential for business. Yet, subject to the combined influence of two opposing rights: contract law and competition law, they raise many questions in practice. Is market transparency compatible with freedom of contract? If so, will this freedom emphasize the existing economic imbalances? Can the law-maker admit negotiability without abandoning the idea of effective controls? Although they exist, all these obstacles do not seem insurmountable. As long as their roles are clearly redefined, contract and competition laws can be reconciled. Thanks to a fixed and transparent basis as well as limitations, the parties would be allowed to tailor their agreement to their needs without any risk of imbalance. Formalized, such contract would also make the legislator sure that it doesn’t contain competition distorting clauses

Texto completo da fonteResumo:
L’insertion du contrat dans la vie sociale a mis en lumière des conflits d’intérêts entre d’une part les parties contractantes, qui souhaitent que leurs prévisions contractuelles se réalisent et d’autre part, les tiers, qui ne veulent pas voir leur liberté limitée par un contrat auquel ils n’ont pas consenti. La théorie de l’opposabilité, assurant une fonction préférentielle, tranche le conflit d’intérêts antagonistes en réservant aux parties contractantes une exclusivité, la connaissance étant alors le critère d’attribution de cette situation préférentielle. Dès lors tout tiers qui avec connaissance incite ou aide un débiteur à violer son obligation contractuelle engage sa responsabilité à l’égard du créancier de cette obligation. Dans un contexte concurrentiel, l’opposabilité du contrat (ou du droit subjectif) va aboutir à créer une zone d’exclusivité en faveur des parties (ou détenteurs de droits) et étouffer la liberté concurrentielle des tiers. Le droit va alors délimiter une zone d’activité pour chacun. Nos travaux de recherches visent à étudier le phénomène d’opposabilité, entendu comme l’effet d’un acte ou fait juridique sur les tiers, dans un contexte concurrentiel ; et le mécanisme de conciliation qu’est l’action en concurrence déloyale. Après l’étude des solutions existantes, nous tenterons de dégager un critère du comportement déloyal permettant une appréhension globale et contextuelle de l’effet de l’acte concurrentiel sur un marché, afin d’ajuster le degré d’opposabilité suffisant à la protection des uns et à la préservation de la liberté concurrentielle des autresLaw rules relations between individuals. From an economic angle, it defines an activity range for each operator. Our research work aims at studying the french concept of “opposabilité” in a competitive background. The question is about analysing the effects of a contract or an exclusive right regarding third competitors; and the reconciliation proceeding that is the action on unfair competition. We will attempt to draw a criterion from unfair behaviour that enables a better analysis of the effect of competitive action on a market and therefore on this market's own operators, to adapt the “opposabilié” degree to allow protection of some and preservation of freedom for others

This chapter presents purely combinatorial results that are needed for the proof of Statement G. The motivation for these results comes from the appearance of divisibility conditions through the factor δn(Σ; α) defined in (15.2) that appears in Theorems 15.3 and 15.4. According to Statement F, the sum of Λsubscript Greek capital letter gamma(α, σ) over an f-packet is equal to the corresponding sum of ΛΔ(α′, σ). In order to prove Statement F, the chapter proceeds by identifying terms in the resulting double sum that can be matched. It considers subsignatures of η and concurrence as an equivalence relation.

Texto completo da fonteResumo:
Swallowing and voice production are important processes enabling a comfortable life. For appropriate alimentation, effective passage of food and fluids through a digestive system is necessary. Interpersonal communication depends on good voice and speech. Conditions associated with swallowing and speech problems leads dysfunctions and seriously affect the patient’s comfort of living. This chapter is a review of medical conditions associated with concurrence of dysphonia and dysphagia. There are a large number of medical conditions leading to the simultaneous occurrence of swallowing problems and hoarseness. The diversity of disorders is a serious interdisciplinary issue. Diagnostics of concurrent dysphagia and dysphonia is complicated and requires a holistic interdisciplinary approach. The reasons include functional and organic dysfunctions, neurological conditions, tumors, vascular disorders, autoimmune inflammations, post-operative complications, post-COVID complications, and others. Our research was conducted by reviewing PubMed and Scopus network using key words “dysphagia”, “dysphonia”, “hoarseness.” We found 966 publications, then narrowed the search to 99 articles describing medical conditions and case reports, which present with dysphagia and dysphonia occurring together. Detailed analysis enabled us to categorize the disorders into groups, depending on characteristics and body region involved in the pathological process. Finally, the description of the medical conditions was done systematically according to those groups.

Texto completo da fonteResumo:
Chronic diseases are the leading cause of mortality and morbidity. A significant contribution to the burden of chronic diseases is the concurrence of co-morbidities. Heart failure (HF) is a complex, chronic medical condition frequently associated with co-morbidities. The current care approach for HF patients with co-morbidities is neither capable to deliver personalised care nor to halt the on-going increase of its socio-economic burden. Our approach aims to improve the complete care process for HF patients and related co-morbidities to improve outcome and quality of life. This will be achieved by the proposed standardised yet personalised patient-oriented ICT system that supports evidence-based clinical decision making as well as interaction and communication between all stakeholders with focus on the patients and their relatives to improve self-management. We propose that such a system should be build upon a novel European-wide data standard for clinical input and outcome and that it should facilitate decision making and outcome tracking by new collective intelligence algorithms.

In today's world, smartphones are ubiquitous and feature high-quality cameras and video recording capabilities. The camera shake, shadows, or other environmental factors lead to poor video, even in low-lighting situations with a high-end camera. To preserve and enhance low-light mobile video, a wavelet energy-based adaptive retinex algorithm is proposed. The first step in the method is to extract frames from the composite video before it is fed into the algorithm in HSV space. The authors then apply the wavelet energy-based adaptive retinex algorithm to the dynamic range-extended value channel. Lighting conditions that cause video degradation are restored adaptively to their natural brightness. A color restoration technique that improves the conventional retinex method fixes the gray world violation problem. Wavelet energy is used as a metric in concurrence with the retinex algorithm to objectively validate image enhancement quality. An experimental work of more than 300 still images and videos show that the proposed technique outperforms the current state of the art.

Abstract The question, as usual, was where to go from there. Kissinger himself conceded the limits of Sinai II in a speech to the Greater Cincinnati Chamber of Commerce on September 16, 1975. “I want to emphasize that the United States did not help negotiate this agreement in order to put an end to the process of peace but to give it new impetus,” he told the U.N. General Assembly a few days later. There were unusual opportunities for progress, he added hopefully, but they had to be seized before they disappeared. It was clear, for all that, that the opportunities were both indeterminate and open-ended. “Impeccable” execution of the Sinai accords was a first condition, the secretary emphasized. Washington was prepared to “make a serious effort to encourage negotiations between Syria and Israel,” he continued bravely. But the third course, involving exploration of “possibilities for perhaps a more informal multilateral meeting to assess conditions and discuss the future,” already led into the mists. “We have no preference for any particular procedure,” the secretary added. Acknowledging superpower concurrence that another war in the region would be disastrous, and the persisting willingness of the United Nations to dispatch casques bleues, he let it be known that the United States was prepared to pursue “whatever process seems most promising.”

This study serves to delineate the effects of material on the lifespan of a polymeric roller rubbing against a steel wire. Four materials, namely nylon, polyester, borosilicate glass and epoxy are the manipulated variables in conducting a simulation with a steel wire. A block-on-ring machine was used to conduct the tribo-experiments under dry contact condition. In concurrence with average operating conditions, the machine was set to 0.15 m/s sliding velocity, at an applied load of 10 N. Worn surfaces of the polymer were subsequently studied under optical microscopy. Frictional and wear resistance results were presented versus time for a predetermined duration. There is a strong correlation between the wear resistance and material hardness but the contrary is found with elongation at break. Findings revealed better wear resistance in epoxy due to its higher hardness. The improvement attained with reference to nylon was approximately 68%. The optical images of worn surfaces which sustained scratches and grooves implied that the contact mechanism was that of abrasion.

A thermodynamic model for simulation the performance of a four-stroke direct-injection (DI) diesel engine is developed. The simulation model includes detailed sub-models for fuel burning rate, combustion products, thermodynamic properties of working fluid, heat transfer, fluid flow, and both soot and NOx formation mechanisms. To validate the model, comparisons between experimental and predicted results for different engines, operating under different conditions were conducted. Comparisons show that there is a good concurrence between measured and predicted values. An optimization analysis is conducted for seeking an optimum variation of compression ratio to achieve pre-set objective target of constant minimum brake specific fuel consumption (bsfc). The optimization analysis is performed under the constrain that the maximum pressure and temperature inside the cylinder not exceed the maximum allowable pressure and temperature of the conventional engine (constant rc). Varying compression ratio is optimized with the previous condition. Results indicated that, at the values of rc ranged between 16.4 and 17.8, the optimum bsfc is attained with an increase in brake power by about 3.8%, while the bsfc and soot emission are reduced by about 4.4% and 21%, respectively. In addition to an increase in NOx, maximum pressure (pmax), and maximum temperature (Tmax) by about 75%, 6% and 4.3%, respectively.

Application of gas turbines in the off-shore oil and gas market has been successful for many years, utilizing both industrial gas turbines, as well as, aeroderivative types. Today, many operators in this market are pursuing the use of converted oil tankers and purpose-built barges — called Floating Production Storage and Off-Loading vessels (FPSO) — and semi-submersible or tension-leg platforms as alternative means of drilling for and production of oil and gas in much deeper waters than before, gaining flexibility of operation and reduced overall costs. Due to the special requirements of extreme conditions experienced on board a FPSO vessel, each application involves a considerable amount of pre-design to determine the gas turbine package required capability to satisfy needed reliability. Additionally, international and local maritime regulatory bodies and classification societies concurrence/approval generally are required to authorize vessel operation. The intent of the “Code of Construction and Equipment of Offshore Drilling Units” is to recommend design criteria, construction standards, and other safety measures in order to minimize risk to the vessels, platforms, personnel and to the environment. To incorporate these requirements into a standardized cost effective gas turbine system, this paper outlines the design features of such a package for installation on FPSO vessels.

Abstract The operational environment of long-distance oil and gas pipelines is characterized by its complexity, which can lead to stress concentration and localized defects over time, consequently increasing the operational risks. One emerging technology for evaluating the structural integrity of these pipelines is non-destructive testing based on vibration characteristics. This paper elucidates the operating principle of knock detection technology. Utilizing X80 pipeline steel, we establish a finite element model for knock detection and reveal the relationship between pipeline stress state and vibration acceleration signals from small plate specimens. To validate the reliability of the finite element model, we conduct knock detection experiments under uniaxial tension. Building upon this foundation, we delve into the vibration response characteristics of small pipes under various stress conditions. Our results demonstrate a strong concurrence between the outcomes from small plate specimens and small pipes, with a close correlation between intrinsic vibration frequency and pipeline stress in vibration acceleration signals. These findings serve as a crucial stepping stone for the practical application of knock detection methods based on vibration characteristics. It is established that this method can effectively assess the stress state of X80 pipeline steel and represents a dependable approach for evaluating the serviceability of pipelines.

Texto completo da fonteResumo:
Abstract Polyacrylamide polymer flooding is an established EOR technique to reduce the water/oil mobility ratio and improve sweep efficiency. Polyacrylamide polymers are non-Newtonian fluids whose viscosity depends significantly on shear rate in addition to several other parameters, such as brine salinity and hardness, temperature, polymer concentration, chemical composition, and molecular weight. Each oil reservoir has unique brine compositions, expected shear, and temperature conditions. Estimating the polymer solution's in situ viscosity under these conditions can be quite challenging, requiring expensive and time-consuming rheological lab experiments. Machine learning has recently gained popularity and has been applied successfully in many sectors, including the oil & gas industry, to develop predictive models and forecasting tools. With more than 30 years of experience in polymer EOR projects globally, SNF has compiled a large rheological dataset, including approximately 75,000 lab experiments measuring the viscosity of its synthetic polymers under different reservoir conditions. In this study, different machine learning algorithms have been tested on SNF's rheological dataset to predict polymer viscosity for any given polymer type and concentration under certain reservoir conditions. The best results were achieved using a Random Forest algorithm, the results of which have been presented here. The model predictions are based on the following eight input features: active polymer concentration, shear rates, brine total dissolved solids (TDS), hardness, temperature, polymer molecular weight, and chemistry (ATBS percentage and Acrylamide percentage). Based on preliminary investigations, the results obtained are promising, with an R-Squared regression score of 89.6 % and a mean absolute percentage error of 35.8%. The model's results have helped SNF better understand the impact of these different parameters on polymer viscosity and can be used for improved quality control of lab measurements generated across the globe. This tool aims to aid product development by providing in silico data in concurrence with in situ experiments, driving a robust development process.

Texto completo da fonteResumo:
Recent experience has shown that many utilities have installed new feedwater flow measurement instrumentation, which is designed with new, proven technology that more accurately monitors feedwater flow and therefore, allows for improved thermal power level calculations. As a result of this new approach, many utilities have been able to extend limited power upgrades to the tune of 1.4%, and yet with no noticeable additional environmental impact. These electric power increases are generally attributable to the large design margins included in the original nuclear power plant designs and in addition, to the technological advances that have been made to the nuclear industry. Power increases are now carried out by several nuclear utilities in the United States with the NRC’s concurrence. Current nuclear power plants are providing cheap, reliable and affordable electricity to help meet current energy growing demands. As a result of this, power uprate increases are encouraged. Current economic conditions strongly favor power uprates and plant life extensions. In the early 1990s, a limited power uprate program was initiated, but due to complex design reviews, this was not steadfastedly recommended during this time period. Nuclear Steam Supply Systems (NSSS) vendors performed a key role in this nuclear power uprate program. This paper discusses structural and piping qualification review required to achieve these power uprate programs, currently being performed by nuclear utilities in the United States.

Texto completo da fonteResumo:
The objective of the present work is to develop a dynamic electro-thermal model for photovoltaic cells to optimize both electrical and thermal performance of such systems. The thermal model is developed by generating the equivalent RC network (resistance-capacitance) parameters. Then, the thermal model is combined with electrical model and implemented by PSIM simulation program to evaluate performance parameters for any predefined operating condition. The electro-thermal model predicts instantaneous temperature of photovoltaic device at the actual circuit working conditions. Consequently, the temperature rise during the system startup and during load transient is investigated. The thermal model predicts the junction temperature based on transient heat dissipation calculated from the electrical model. The calculated junction temperature is used as an input to the electrical model. The factors that control the junction temperature are module reaching irradiance, optical properties of the photovoltaic cell, photovoltaic conversion efficiency, heat transfer and electrical characteristic of the load. If the junction temperature exceeds a certain limit, it causes hotspot on the photovoltaic module surface. Consequently, the formed hotspots result in reducing the system efficiency and life time. The predicted dynamic behavior of photovoltaic cell is compared with theoretical predictions and other reported data in order to validate the developed model. The obtained results show a good concurrence with the predictions of other works. Detailed comparisons between predicted and measured results are reported and discussed.

Texto completo da fonteResumo:
For the foundation of an industrial complex, auger-cast-in-place piles (ACIP-Piles) have been installed on behalf of the recommendation of a local geotechnical consultant. With respect to the poorly graded sand deposits and the high ground water table, the installation was critically reviewed with respect to the European Code DIN EN 1536. In the course of the installation process of a couple of working piles, extensive soil was drilled by the auger, which led to a loss of soil mass in the vicinity of the pile shafts. A detailed engineering analysis came to the conclusion, that the reasons of the damage can be attributed to a concurrence of the subsurface soil conditions, the chosen drilling technique, the choice of the contractor as well as the workmanship. However, a distinct soil loosening could also be measured by a plenty of cone penetration tests in the vicinity of those working piles, which have apparently been installed properly. Surprisingly, the compact sand layers were much more affected by the installation process than the loose deposits. These findings lead to the conclusion, that the installation process of ACIP piles has to be critically evaluated during the construction process and may become a decisive design influence in the case of a pile design by empirical pile capacity magnitudes.

Texto completo da fonteResumo:
When working together, human and robots complement each other’s abilities yielding more efficient task execution. The cognitive abilities of humans are complemented by physical robot support, reducing fatigue and stress, particularly in repetitive tasks. A robot-human handover is an example of interaction in which human and robot act in temporal and spatial concurrence, with particular relevance in scenarios without temporary object placement, such as service robotics. This physical and cognitive interaction between human and robot requires coordination and effective communication. This work concerns a robot-human object handover with a robot arm equipped with a two-finger robotic gripper. Mutual task awareness between human and robot is attained by both haptic and visual feedback. A force/torque sensor measures the grasp forces imposed by the human which eventually trigger the release of the object. The handover behavior releases the object once force and torque thresholds are exceeded. The decision rule aggregates direct and integral measures of the force/torque signal. In other words, the gripper releases either if the human imposes a significant force or a medium force over an extended period of time. Furthermore, a lighting ring in the robot wrist provides the user with visual feedback on the force exerted and indicates a forthcoming grip release. The evaluation of the algorithm considers the qualitative individual human perception of the naturality of the handover with and without visual feedback. Results show that merely static thresholds w.r.t. direct force and torque measures provide an effective handover but parameterization proved difficult as the algorithm does not adapt to the conditions of the handover. An adaptive threshold based on integral measures attained better results when parameterized for maximum adaptability. Furthermore, visual feedback has a positive impact on the human perception of the naturality of the handover as users receive information on the required force for attaining an object release.

In ASME 2015 International Mechanical Engineering Congress and Exposition. American Society of Mechanical Engineers, 2015. http://dx.doi.org/10.1115/imece2015-51154.
Texto completo da fonteResumo:
Tolerance modeling is the most basic issue in Computer Aided Tolerancing (CAT). It will negatively influence the performance of subsequent activities such as tolerance analysis to a great extent if the resultant model cannot accurately represent variations in tolerance zone. According to ASME Y14.5M Standard [1], there is a class of profile tolerances for lines and surfaces which should also be interpreted correctly. Aim at this class of tolerances, the paper proposes a unified framework called DOFAS for representing them which composed of three parts: a basic DOF (Degrees of Freedom) model for interpreting geometric variations for profiles, an assessment method for filtering out and rejecting those profiles cannot be accurately represented and a split algorithm for splitting rejected profiles into sub profiles to make their variations interpretable. The scope of discussion in this paper is restricted to the line profiles; we will focus on the surface profiles in forthcoming papers. From the DOF model, two types of errors result from the rotations of the features are identified and formulized. One type of the errors is the result of the misalignment between profile boundary and tolerance zone boundary (noted as type 1); and if the feature itself exceeds the range of tolerance zone the other type of errors will form (noted as type 2). Specifically, it is required that the boundary points of the line profile should align with the corresponding boundary lines of the tolerance zone and an arbitrary point of the line profile should lie within the tolerance zone when line profile rotates in the tolerance zone. To make DOF model as accurate as possible, an assessment method and a split algorithm are developed to evaluate and eliminate these two type errors. It is clear that not all the line features carry the two type errors; as such the assessment method is used as a filter for checking and reserving such features that are consistent with the error conditions. In general, feature with simple geometry is error-free and selected by the filter whereas feature with complex geometry is rejected. According to the two type errors, two sub-procedures of the assessment process are introduced. The first one mathematically is a scheme of solving the maximum deviation of rotation trajectories of profile boundary, so as to neglect the type 1 error if it approaches to zero. The other one is to solve the maximum deviation of trajectories of all points of the feature: type 2 error can be ignored when the retrieved maximum deviation is not greater than prescribed threshold, so that the feature will always stay within the tolerance zone. For such features rejected by the filter which are inconsistent with the error conditions, the split algorithm, which is spread into the three cases of occurrence of type 1 error, occurrence of type 2 error and concurrence of two type errors, is developed to ease their errors. By utilizing and analyzing the geometric and kinematic properties of the feature, the split point is recognized and obtained accordingly. Two sub-features are retrieved from the split point and then substituted into the DOFAS framework recursively until all split features can be represented in desired resolution. The split algorithm is efficient and self-adapting lies in the fact that the rules applied can ensure high convergence rate and expected results. Finally, the implementation with two examples indicates that the DOFAS framework is capable of representing profile tolerances with enhanced accuracy thus supports the feasibility of the proposed approach.
