Lastbalanseringsalgoritmer : En utvärdering av lastbalanseringsalgoritmer i ett LVS-kluster där noderna har olika operativsystem

Brissman, Alexander, Brissman, Joachim January 2012 (has links)
Denna rapport behandlar en undersökning av olika lastbalanseringsalgoritmer i Linux Virtual Server. Undersökningen har gjorts i ett webbkluster (Apache var webbservern som användes) med tre heterogena noder, där operativsystemet var den detalj som skiljde dem åt. Operativsystemen som ingick i undersökningen var Windows Server 2008 R2, CentOS 6.2 och FreeBSD 9.0. De faktorer som undersöktes mellan de olika algoritmerna var klustrets genomsnittliga svarstid vid olika belastning och hur många anslutningar som kunde hanteras av klustret, detta gjordes med verktyget httperf. Undersökningen ger svar på hur ett heterogent webbklusters genomsnittligasvarstid och arbetskapacitet kan skilja sig åt beroende på vilken algoritm som används för lastbalansering. Resultatet visar att den genomsnittliga svarstiden håller sig låg tills en hastig stigning inträffar. Shortest Expected Delay och Weighted Least-Connection Scheduling kunde hantera störst antal anslutningar. / This report covers an investigation of different load balancing algorithms in Linux Virtual Server. The investigation was done in a web cluster (with Apache as the software being used) consisting of three heterogeneous nodes, where the operating system was the detail that differentiated the nodes. The operating systems that were used in the investigation were Windows Server 2008 R2, CentOS 6.2 and FreeBSD 9.0. The factors examined were average response time at different load and how many connections the cluster could cope with, these factors were examined by measurements taken with the tool httperf. The investigation gives an answer to how a heterogeneous web clustersaverage response time and working capacity can be affected by the choice of load balancing algorithm. The result shows that the average response time stays low until a sudden rise occurs. Shortest Expected Delay and Weighted Least-Connection Scheduling could handle the largest number of connections.

The Amazon Archers of England : Longbows, gender and English nationalism 1780–1845

Arnstad, Henrik January 2019 (has links)
In the 1780s the medieval weapon of war; the English longbow, enjoyed a renaissance, as historical archery became a fashionable recreation among the English aristocracy. Later, during 1819-1845, longbow archery developed into a mass movement, as it spread downwards in the English class system, into the bourgeoning middle class. During the entire time period of 1780-1845, the “English warbow” was instrumental in producing a specific English (i.e. not British) nationalistic memory culture regarding the medievalmilitary triumphs of the “English bowmen” in battles of old, against French and Scottish forces, as well as reproducing a nationalistic narrative surrounding the English national hero and master-archer Robin Hood. The English longbow, as an object, became a mani- festation of English nationalism. An important fact was that both men and women were included as archers, despite the masculine context of the memory culture surroundingmilitary archery, the celebration of medieval English battlefield victories and the man- liness of the English “bowmen”. How did England come to view the female archer as an ideal for English women, while at the same time publicly upholding a patriarchal doctrine of a feminine “private sphere” womanhood, whereby women should be constrained to the domestic space as housewives, mothers and daughters? How was the English inclusion of females in the nationalistic public sphere of longbow archery made possible, communica- ted and reproduced? In summary, this study is about how longbow archery was manife- sted in the context of the rise of English modern nationalism and how women were inclu- ded – or rather included themselves – as English longbow archers. As the study shows, the answers exists in an inter-relating web of English memory culture regarding warfare and historical archery; gender constructions and female agency; constructions of English national identity and English nationalism within a British context; and class developments in English society. This accounts for how the Amazon Archers of England came to exist from 1780-1845. / På 1780-talet fick det engelska medeltida krigsvapnet; den engelska långbågen, en ovän- tad och plötslig renässans i England, när historiskt bågskytte blev en hobby på modet inom den engelska aristokratin. Efter Napoleonkrigens slut 1815 utvecklades skyttet till enfolklig massrörelse, inom den växande och allt mer inflytelserika engelska medelklassen. Under tidsperioden 1780-1845 blev den engelska långbågen (The English longbow ellerThe English warbow) instrumentell i produktionen av en specifikt engelsk – det vill sägainte brittisk – nationalistisk minneskultur, utifrån de medeltida engelska bågskyttarnassegrar på slagfälten, i krig mot franska och skotska arméer. Parallellt förstärktes de natio- nalistiska narrativen kring den engelske nationalhjälten och långbågeskytten Robin Hood. Den engelska långbågen, som objekt, blev en manifestation av engelsk nationalism. En viktig del av den engelska långbågskytterörelsen var inkluderingen av både kvinnor och män, trots skyttets karaktär av maskulin krigiskhet och militärhistoria, angående medel- tida krigståg, där ”the English bowman” hade triumferat. Faktum är att den kvinnliga bågskytten hyllades som ett ideal för engelska kvinnor, samtidigt som patriarkal brittisk doktrin dikterade att kvinnor borde hålla sig innanför hemmets väggar, i den privata sfä-ren, medan den offentliga sfären (yrkeskarriär, politik, idrott, etc.) borde vara ett exklusivtmanligt utrymme. Kvinnor skulle vara fruar, mödrar eller döttrar – inte krigare. Hur vardessa bägge kvinnoideal möjliga att förena? I denna fråga återfinns denna studies kärna. Hur konstruerades engelsk krigshistorisk nationalism 1780-1845 kring den engelska långbågen? Hur inkluderades kvinnor i denna maskulina nationalism? Hur producerades, kommunicerades och reproducerades kvinnlig agens i en militärhistorisk nationalistiskdiskurs, som i andra europeiska länder (exempelvis Sverige) ansågs självklart exklusivtmanlig? Sammanfattningsvis visar denna studie hur den engelska långbågen blev central för den gryende engelska moderna nationalismen 1780-1845, och hur kvinnor inkluderades – eller snarare inkluderade sig själva – i denna nationalism, som långbågeskyttar. Studien visar att svaren på forskningsfrågorna återfinns i en sammanflätad väv av engelskminneskultur, angående historiska krig och bågskytte; genuskonstruktioner och kvinnlig agens; konstruktioner av engelsk nationell identitet och engelsk nationalism; samt engel- ska samhällsutvecklingar under introduktionen av modernitet och industrialism. Allt detta berättar historien om hur de engelska bågskytte-amazonerna–The Amazon Archers of England–blev en realitet 1780-1845.

Habitat selection in translocated bird populations : the case study of Stewart Island robin and South Island saddleback in New Zealand

Michel, Pascale, n/a January 2006 (has links)
The choice of a place to live and reproduce is crucial for species� survival in providing them with adequate resources and shelter from predators or climatic conditions. Determining habitat suitability in endangered species is important for the success of translocation as a conservation tool. In addition, understanding mechanisms (source/sink system versus ecological traps) that drive habitat selection in translocated animals may be critical to population viability. In New Zealand, where ecosystems are highly vulnerable to extinction, habitat restoration on predator-free off-shore islands is an important recovery tool. Therefore, there is a need to understand the relationship between the establishment of the translocated populations and the characteristics of their new environment. Previous research indicated that re-introduced populations of Stewart Island robin (Petroica australis rakiura - Toutouwai) and South Island saddleback (Philesternus carunculatus carunculatus - Tieke) on Ulva Island (Stewart Island), New Zealand, showed preferences for coastal habitats that were characterized by low-lying dense vegetation and open ground cover. In this study, we further investigated territorial establishment in these two populations since re-introduction and looked at how birds utilised the landscape. I hypothesised that sites colonised soon after re-introduction were of high quality and later on, birds moved into unsuitable habitats. I defined habitat quality at a micro-scale in terms of vegetation structure, nest characteristics and food availability. I modeled bird presence and nesting success in relation to habitat components to determine factors in the environment that influenced breeding site selection and contributed to successful nesting in these two species. I discussed results in comparison to similar bird-habitat models developed for the South Island saddleback population on Motuara Island (Marlborough Sounds) and examined explanatory variables in each model. Translocated birds in the three studied populations first established territories in coastal scrub, and in the following years moved into larger coastal forest stands. Although vegetation structure was the primary variable explaining site selection in these populations, vegetation composition should still be considered important as it dictated the suitability of nesting substrate and the availability of food items. There was no evidence that first-colonised areas were more suitable habitats, and I concluded that these cases could not be used as examples of ecological traps. Instead, results suggested that with increased density robins and saddlebacks on Ulva have more recently settled in sites less suitable to nesting and foraging, thus underlying a source/sink structure. However, the sparse distribution of food items on Motuara contributed to a lack of territorial behavior and environmental effect on breeding success; therefore a source/sink system could not be confirmed in this population. I recommended that future translocation sites give preference to mixed-size stands with broadleaved species that are characterised by dense canopy below 4 m height and with suitable cavities in live trees. Lastly, due to robins� and saddlebacks� attraction to conspecifics and their territorial behavior, resources evenly distributed across the landscape could also increase their survival and reproductive success.

La main juste des manageurs : les stratégies visibles et invisibles de justice corrective des manageurs et leurs antécédents

Nadisic, Thierry 25 September 2008 (has links) (PDF)
La recherche traditionnelle en justice organisationnelle a montré l'impact que les sentiments de justice et d'injustice ont sur un grand nombre d'attitudes et de comportements des salariés. La présente thèse a étudié les formes et les antécédents des comportements de justice corrective des manageurs de quatre façons complémentaires. Dans le premier chapitre ont été explorés les antécédents de la tendance des manageurs à ne pas se comporter de façon interactionnellement juste pour corriger des procédures formelles injustes et des allocations de récompenses injustes - un phénomène connu sous le nom de « effet Churchill ». Une expérience (n=118) a montré que plus les manageurs ont trouvé la situation injuste, moins ils ont eu tendance à la corriger en utilisant la justice informationnelle. De plus moins les manageurs étaient assertifs, moins ils ont été enclins à corriger l'injustice en utilisant la justice interpersonnelle. Par ailleurs l'identification des manageurs à l'organisation était négativement reliée à leurs comportements d'injustice interpersonnelle et informationnelle et modérait la relation entre leurs sentiments de justice procédurale et leurs comportements de justice informationnelle. Les résultats ont aussi montré que les manageurs pouvaient utiliser d'autres stratégies de justice corrective en plus de la justice interpersonnelle et informationnelle. Dans le second chapitre, d'autres stratégies de justice corrective ont été identifiées. Une étude exploratoire (n=35) a été menée qui a révélé une stratégie de correction de l'injustice au travail ayant fait l'objet de peu de recherches : le manageur réalisant des allocations complémentaires de bénéfices appartenant à l'entreprise, pour des utilisations autres que formellement prévues, pour rétablir la justice « sous le manteau ». Cette stratégie a été nommée la stratégie des remèdes invisibles et il a été fait référence à son utilisation par les manageurs sous le terme de stratégie Robin des Bois. Cette seconde étude a comparé les formes et les antécédents de cette stratégie à ceux des autres stratégies managériales de justice corrective. Dans le troisième chapitre la littérature de la justice organisationnelle et celle de la sociologie du vol organisationnel ont été reliées de façon à développer un modèle conceptuel de la stratégie Robin des Bois. Des propositions de recherche ont été faites concernant les formes que les remèdes invisibles pouvaient prendre au travail et les conditions qui rendaient plus probable leur utilisation par les manageurs. Dans le quatrième et dernier chapitre, certains aspects du modèle proposé ont reçu une confirmation empirique préliminaire, en l'occurrence l'importance de l'injustice distributive, de l'injustice interpersonnelle et de l'identité morale des manageurs comme prédicteurs de l'allocation de remèdes invisibles par les manageurs. De façon spécifique, une étude par scénario (n=187) a montré qu'une triple interaction entre justice distributive, justice interpersonnelle et identité morale prédisait la stratégie Robin des Bois

Le mythe réactualisé dans La citadelle des ombres, tome 1 de Robin Hobb : pour une symbolique de l'immortalité

Jackson-Corbeil, Stéphanie-Kim 01 1900 (has links) (PDF)
Ce mémoire propose une étude du mythe réactualisé à l'intérieur du premier tome de La Citadelle des Ombres de Robin Hobb, publié en 2000. Il révèle des personnages qui, par leurs interactions, mettent en œuvre et confirment, sur un arrière-plan mythologique modernisé, un désir ancestral et perpétuel d'immortalité chez l'homme, né de l'angoisse générée par la mort à venir. En plus de se nourrir des ouvrages sur la fantasy et sur la survivance des mythes dans les récits contemporains, ce mémoire s'appuie sur des notions anthropologiques du symbole et du mythe de même que sur les mythes autochtones d'Amérique du Nord. Le premier chapitre est consacré à l'approche mythocritique ainsi qu'aux réflexions sur la fantasy. Ce chapitre permet de démontrer le rapport entre la fantasy et le merveilleux, issu de l'exploitation massive d'un héritage mythique. En outre, il expose la méthodologie qui permet de déceler les indices mythiques présents dans l'œuvre. Le second chapitre propose l'analyse des contours du mythe et du symbole sous un angle anthropologique, par le biais de l'imaginaire. Il permet de découvrir les constellations particulières et les indices mythiques contenus dans l'œuvre. L'imagination, structurée sur l'antithèse, fait ressurgir dans La Citadelle des Ombres, tome 1, une dualité des temps entre temps en progression et temps mythique sacré ainsi qu'entre la vie et la mort par un retour éternel du cycle de naissance/mort/renaissance. Tissés en constellations, les symboles investissent les mythes et permettent de découvrir une symbolique archétypale de l'immortalité. Le troisième chapitre est consacré aux lieux de rencontre avec l'animal, sous différents angles et points de vue. Ce chapitre permet entre autres de découvrir une constante dans la mythologie autochtone d'Amérique du Nord où les animaux sont omniprésents. Par une vision holistique de l'osmose homme/nature, en regard des personnages du corpus et des indices mythiques qu'il contient, ce chapitre démontre que la nature humaine qui ne fait qu'un avec la nature animale, ne peut souffrir de cette dualité puisque la fusion des contraires permet le retour à l'unité. En s'unissant, l'homme et l'animal permettent à l'homme d'accéder à l'immortalité. Le mémoire se conclut sur le fonctionnement global du mythe réactualisé dans La Citadelle des Ombres, tome 1 et de la symbolique archétypale d'immortalité qui en découle. ______________________________________________________________________________ MOTS-CLÉS DE L’AUTEUR : mythocritique, imaginaire, fantasy, symbole, immortalité, mythe autochtone d'Amérique du Nord, temps, hybridité homme/animal.

Optimisation de l'ordonnancement sous contrainte de faisabilité

Grenier, Mathieu 26 October 2007 (has links) (PDF)
Notre objectif est la conception d'algorithmes d'ordonnancement temps réel en-ligne faisables (i.e., garantissant le respect des contraintes temporelles imposées au systèmes) optimisant 1) l'utilisation de la plate-forme d'exécution (i.e., utiliser au mieux le potentiel de la plate-forme d'exécution tout en garantissant le respect des contraintes temporelles imposées au système) et/ou 2) optimisant des critères de performances<br />propres à l'application.<br /> <br />Deux cas ont été analysés : le cas de tâches indépendantes périodiques s'exécutant sur un processeur et le cas de flux de messages indépendants périodiques sur un réseau de terrain avec accès au médium priorisé.<br /><br />Nous avons donc proposé pour traiter les deux problèmatiques abordées :<br />1) des méthodes de configurations permettant d'optimiser l'utilisation de la plate-forme d'exécution en fixant d'une manière appropriée les paramètres : des politiques ou des activités du système considéré. Deux études ont été conduites dans ce cadre~: l'allocation des ``offsets'' dans les systèmes ``offset free'' et l'allocation de priorités, de politiques et de quantum dans<br />les systèmes conformes au standard Posix~1003.1b,<br />2) une nouvelle classe de politiques d'ordonnancement permettant<br />d'optimiser des critères de performances propres à l'application.

Exploring women's complex relationship with political violence: A study of the weathermen, radical feminism and the new left

Churchill, Lindsey Blake 01 June 2005 (has links)
In this thesis I use the radical, pro-violent organization the Weathermen as a framework to examine women and feminisms complex relationships with violence. My thesis attempts to show the many belief systems that second wave feminists possessed concerning the role(s) of women and violence in revolutionary organizations. Hence, by using the Weathermen as a framework, I discuss various feminist essentialist and pacifist critiques of violence. I also include an analysis of feminists who, similar to the Weathermen, embraced political violence. For example, radical feminists Robin Morgan and Jane Alpert criticized the Weathermens violent tactics while other feminists such as Ti-Grace Atkinson and Valerie Solanas advocated that women pick up the gun in order to destroy patriarchal society. In addition, I analyze the stereotypes of the violent female, which have often been supported by feminists and non-feminists alike. Thus, the stereotyped nature of the violent female does not allow for the complexities that accompany the many reasons why women commit politically motivated crimes. Understanding the role women played in the Weathermen is an important task because womens roles and representation in radical, New Left organizations have often been ignored, overlooked and reproduced by revisionist analyses. Though revolutionary groups from the sixties and seventies were important and progressive in many ways, my thesis will examine the phenomenon of silencing womens voices in these organizations and how this silencing inspired women to find voice in their own movements. Furthermore, I am also interested in radical second wave feminists belief systems and histories concerning violence, particularly since they have rarely been delved into by historians or feminist researchers.
