Une grande partie des solutions de mobilité pour les fauteuils roulants se concentre sur l'aide au déplacement de l'utilisateur.La plupart des fauteuils roulants visent à offrir une solution adaptée pour assurer la conduite adaptée et la stabilité pour l'utilisateur.Le projet Volting, développé au LISV depuis 2020, propose une nouvel axe d'étude. Il s'agit du développement d'un fauteuil roulant capable d'offrir une plus grande mobilité posturale pour l'utilisateur basée sur une inclinaison latérale.L'objectif suivi dans le projet Volting est de proposer une réappropriation de son corps avec ce déséquilibre. Dans cette optique, une première proposition a été réalisée. Elle consiste en un fauteuil roulant capable de basculer latéralement proportionnellement à l'inclinaison de l'utilisateur. Cette liberté de mouvement supplémentaire donne à l'utilisateur une plus grande capacité de gestes corporels. C'est dans ce contexte que la danse en fauteuil roulant a été choisie comme domaine d'application.Dans cette thèse, le prototype Volting a été étudié sous trois points de vue : l'interaction, la commande et l'assistance.Tout d'abord, l'interaction entre l'utilisateur et Volting fait référence à la relation entre d'inclinaison du tronc de l'utilisateur et d'inclinaison de Volting. Elle a été analysée afin de rechercher un comportement approprié. Ainsi, une analyse du modèle a été réalisée pour étudier les paramètres impliquées dans cette interaction. Des expériences ont montré que l'utilisation de notre modèle fournit les paramètres appropriés pour une cinématique correcte.Le deuxième axe d'étude porte sur le contrôle du Volting par son usager. Ainsi, l'utilisation d'un dispositif multi-capteurs, appelé WISP, a été proposée. Ce dispositif prend comme entrées de commande la posture du tronc de la personne ou la position de ses mains afin de contrôler le Volting. La logique de contrôle mise en œuvre permet à l'utilisateur de contrôler le fauteuil roulant avec une plus grande liberté dans l'exécution de gestes. WISP a été testé par une professionnelle et une amatrice de la danse en fauteuil roulant. Cela montre leur adaptation rapide dans l'utilisation du dispositif. Cela montre aussi leur motivation envers la pratique de sa danse.Le troisième axe d'étude porte sur l'utilisation de l'assistant à l'inclinaison, nommé "Glissiere" dans Volting. Ce dispositif repose sur le décalage de l'assise de l'utilisateur pour favoriser ou contrer l'inclinaison latérale de Volting et donc du corps de l'usager. Pour pré-évaluer cette solution, des expériences ont ainsi montré que des utilisateurs présentant différentes morphologies, qui n'arrivaient pas à utiliser Volting à sa pleine capacité, pouvaient utiliser Volting grâce à cet assistantA significant portion of mobility solutions for wheelchairs focuses on assisting the user's movement. Most wheelchairs aim to provide a tailored solution that ensures appropriate driving and stability for the user. The Volting project, developed at LISV since 2020, introduces a new research direction: the development of a wheelchair capable of offering enhanced postural mobility for the user based on lateral tilting.The main objective pursued in the Volting project is to propose a reappropriation of the user's body with the imbalance caused by the tilting. In this regard, an initial proposition was made, consisting of a wheelchair capable of tilting laterally in proportion to the user's inclination. This additional freedom of movement provides the user with a greater capacity for bodily gestures, and it is in this context that wheelchair dancing was chosen as the application domain.In this thesis, the Volting prototype was studied from three perspectives: interaction, control, and assistance.Firstly, the interaction between the user and Volting refers to the relationship between the user's trunk inclination and the tilt of the Volting wheelchair. It was analyzed to find an appropriate behavior. Consequently, a model analysis was conducted to study the parameters involved in this interaction. Experiments demonstrated that the use of our model provided the appropriate parameters for correct kinematics.The second focus of this study is on the user's control of the Volting wheelchair. For this purpose, the use of a multi-sensor device called WISP was proposed. This device takes the user's trunk posture or hand position as input commands to control Volting. The implemented control logic allows the user to control the wheelchair with greater freedom in executing gestures. WISP was tested by a professional and an amateur wheelchair dancer, showing their quick adaptation to the device's use and their motivation towards dance practice.The third area of investigation concerns the use of the incline assistant, named "Glissiere" in Volting. This device relies on shifting the user's seat to promote or counteract the lateral tilt of the Volting wheelchair and, consequently, the user's body tilt. To pre-evaluate this solution, experiments showed that users with different morphologies, who were unable to use Volting to its full capacity, could use Volting with the assistance of "Glissiere."

Der volle Inhalt der QuelleAnnotation:
Cette thèse porte sur la conception de trajectoires interplanétaires, à poussée faible. Les systèmes de propulsion électriques, à poussée faible ou continue, ont permis d'accroître significativement les possibilités de trajectoires, au détriment de mission plus longues. La poussée faible limite également la manoeuvrabilité du système. Afin de parer à ces inconvénients, on utilise généralement des manoeuvres d'assistances gravitationnelles, pour ainsi réduire la consommation et la durée de transfert de la sonde. Le rôle de l'analyste mission est donc de déterminer le meilleur scénario (la séquence de planètes à visiter). De nos jours, ce problème est résolu de manière expérimentale et heuristique. Cependant, bien que la trajectoire produite soit optimale à scénario donné, il n'y a aucune garantie que le scénario en lui-même soit optimal. De plus, cette approche est relativement fastidieuse. Notre objectif a donc été de mettre en place des outils et méthodes permettant de trouver des scénario optimaux pour un objectif fixé. Durant cette thèse, nous avons suivit 2 approches. La première approche consiste à considérer le problème comme étant un problème d'optimisation globale, à variables discrètes. Un ensemble de scénario est étudié à priori. Pour simplifier et faciliter la recherche de séquences, on a modélisé le problème de transfert à poussée faible, en utilisant un principe d'inversion dynamique. Ce modèle utilise des arcs balistiques pour minimiser la consommation, et introduire des degrés de liberté supplémentaires pour satisfaire des contraintes terminales. On a mis au point un algorithme de complexité polynomiale pour résoudre le problème. Afin de réduire le coût calculatoire, nous avons mis en place des contraintes de " pruning " permettant de réduire l'espace de recherche. La deuxième approche consiste à formuler le problème comme un problème de commande optimale, où la dynamique inclut les principaux corps perturbateurs. Le scénario est alors déterminé à postériori. On résoud numériquement le problème au N corps. On montre que les méthodes indirectes (Pontryaguin) et directes (Collocation, Transcription) ne nous permettent pas de résoudre ce problème. On a donc mis au point un solveur de deuxième ordre respectant à la fois les conditions d'optimalité et de précision connues des méthodes indirectes, et des propriétés de robustesse généralement attribué aux méthodes directes.

Le lien profond qui unit le monde des assistantes sociales a celui de l'etat liberal, tient dans l'etroite correspondance entre une ethique affectuelle et un esprit liberal. Cette hypothese est explicitee en recourant a une demarche empirique centree sur l'etude des pratiques des assistantes sociales confrontees a la gestion du dispositif d'insertion sociale et professionnelle de la loi portant sur le revenu minimum d'insertion instauree en decembre 1988. La demarche emprunte a la sociologie de l'experience et a la sociologie clinique pour saisir la place sociale subjective, du point de vue des professionnelles, et definir leurs valeurs mobilisees aux fins de l'accompagnement social de beneficiaires pris dans le processus de degradation progressif de leur statut social. La ressource principalement mobilisee, nommee tantot "ethique affectuelle" lorsqu'on parlera de sa dimension generale philosophique et ideologique, tantot "logique affectuelle", lorsqu'on la travaillera comme logique d'action principale d'une corporation professionnelle, vise principalement a la gratification reciproque des identites respectives. La premiere partie s'interesse a la construction de l'identite d'assistante sociale. Elle s'appuie sur l'exploitation, la valorisation d'un ethos affectuel, ethos du feminin culturellement deja la. Celui-ci sera "travaille" par un dispositif de formation qui s'efforce de le transformer en competence sociale a la disposition d'un projet humaniste. Puis on suit la mise a l'epreuve de la realite de cette identite, et l'on constatera sa destabilisation a travers les conditions de travail qui semblent de plus en plus eloignees du modele pedagogique de l'aide. Le diagnostic est que les a. S. Sont animees par un sentiment de double exclusion. Elles se sentent exclues de la consideration sociale, exclusion qu'elles contribuent a produire en cherchant a se ressourcer dans des entre soi protecteurs qui ont la particularite, par l'auto exclusion qu'ils affichent, de renforcer le mecanisme d'exclusion dont elles se sentent deja victimes. La deuxieme partie, analytique, s'attache a l'exploration des composantes de la logique affectuelle, a les mettre en rapport avec les proprietes individuelles et sociales des assitantes sociales, et plus largement avec les valeurs de la corporation. Ces elements sont petit a petit organises pour visibiliser sa fonction.

Brazil was confronted with high inflation while implementing neoliberal economic policies which were imposed as a panacea to the debt crisis during the process of transition to democracy since 1985. In this context, implementation of structural adjustment and stabilization programs further deteriorated its already unequal distribution of income and exposed the poor to devastating effects of the intermittent crises which were in turn the result of macro-economic policies pursued. Conditional cash transfers which were started to be made in 1995 to extremely poor people against the effects of crises by a few local governments were subsequently expanded in terms of its scope and geography. From 2004 onwards, it was begun to be implemented in the whole country under the title of Bolsa Familia, by President Lula, PT (Labor Party) leader who came to power after the 2002 elections. The program had two objectives: 1. Immediate relief of poverty through the transfer of income, 2. To get people out of poverty and to prevent intergenerational transmission of poverty through conditionalities based on education and health services. Positive impacts were observed in relation to the achievement of the first goalbut the outcomes of the studies on the second goal are not promising. So, the aim of this thesis is to investigate whether the second goal is realizable by examining these studies and their outcomes with reference to the causes of poverty
and to determine the relationship between our results and structural limitations of the program.

La pandémie de maladies cardiovasculaires, actuellement en hausse, pose un problème majeur de santé publique. Malgré les progrès remarquables de la médecine au cours des précédentes décennies, les maladies cardiovasculaires constituent à l’heure actuelle la première cause de mortalité et de morbidité dans le monde. Parmi ces maladies, l’insuffisance cardiaque occupe une place assez importante. Les recherches réalisées au cours de ces dernières années ont permis d’établir que de nombreux facteurs de risque cardiovasculaire comme l’hypertension artérielle, le diabète, l’hyperlipidémie, l’obésité et le tabagisme s’accompagnent d’une dysfonction endothéliale précoce, caractérisée par la diminution de la biodisponibilité du monoxyde d’azote, et d’une rigidité artérielle. La DE semble être le dénominateur commun aux lésions microvasculaires, résultant d’une augmentation du stress oxydatif et d’une activation des voies de l’inflammation. Les conséquences fonctionnelles de ces lésions sont une altération de la capacité de la vasodilatation en réponse aux stimuli physiologiques, une augmentation de la rigidité artérielle et une ischémie tissulaire relative.Pour ce faire, nous avons étudié l’effet des différents facteurs affectant la fonction endothéliale microvasculaire et la biodisponibilité endothéliale du NO chez le sujet sain et pathologique, à l’aide d’une technique non invasive et reproductible appelée « laser Doppler imaging ».Nous avons dès lors démontré que le jeûne intermittent améliore la fonction endothéliale microvasculaire, produit une augmentation de la biodisponibilité du NO chez des sujets masculins en surcharge pondérale par rapport au groupe contrôle, de même qu’il exerce un effet favorable sur la tension artérielle et les paramètres biologiques.Dans un deuxième temps, nous avons examiné les effets des assistances ventriculaires à flux continu centrifuge sur les patients insuffisants cardiaques au stade terminal. Ainsi, nous avons pu montré que ces pompes, n’altèrent pas la dysfonction endothéliale existante chez les patients non assistés, et qu’elles sont respectueuses de la production du vWF, et permettent ainsi de diminuer l’incidence des hémorragies sans pour autant induire de thromboses.Doctorat en Sciences biomédicales et pharmaceutiques (Médecine)

This thesis is about the development of a function that assists the driver of a heavy vehicle to do an estimation over the possibilities to overtake a preceding heavy vehicle. The function utilizes Look-Ahead and vehicle-to-vehicle communication to do a calculation of the distance between the vehicles in some road distance ahead. Consequently the report also contains an investigation of what data that is needed to be known about a vehicle to be able to do a satisfying estimation about this vehicle. The most vital problem is to estimate what velocity the vehicle will get in an uphill/downhill slope. A Simulink model is developed to simulate the function with two independent vehicles. Real tests are also performed to evaluate the velocity estimation part of the function.

Syftet med denna uppsats är att undersöka och fastställa vad som menas med de grundläggande behoven som anges i 9 a § 1 st. LSS, nämligen personlig hygien, måltid, att ta på och av kläder, att kommunicera med andra och annan hjälp som förutsätter ingående kunskap om den funktionshindrade. För att uppfylla syftet har jag för det första valt att undersöka vilka förutsättningar som behöver vara uppfyllda för att någon ska ha rätt till personlig assistans. Slutsatsen som jag här kunnat dra är att det krävs att många förutsättningar är uppfyllda för att assistans ska beviljas. En person behöver till att börja med omfattas av personkretsen i 1 § LSS och därefter behöver det hjälpbehov som föreligger innefatta de grundläggande behoven. Att dessa två förutsättningar är uppfyllda är emellertid inte tillräckligt, för att kunna beviljas assistans måste hjälpbehovet dessutom anses vara av privat och känslig karaktär och således känslig för den personliga integriteten. Rätten till personlig assistans kan dessutom begränsas av föräldraansvaret och om ett hjälpbehov ska bli tillgodosett genom en hälso- och sjukvårdsinsats som således åligger ett landsting att tillgodose.Angående vad de grundläggande behoven innefattar har jag för det första kommit fram till att det som avses med personlig hygien är sådant som faller inom begreppet renlighet, nämligen att tvätta sig, sköta toalettbestyr, tandborstning och nagelklippning. Det måste dock anses vara av den privata och känsliga karaktären. Varma bad och massage har inte ansetts ingå i detta behov då det inte ansetts vara av denna karaktär. Behovet hjälp med måltid innefattar endast själva näringstillförseln. Med detta avsågs tidigare endast att få hjälp att föra maten till munnen men numera är hur näringen tillförs kroppen inte avgörande. Att behöva hjälp med på- och avklädning innefattas även det i grundläggande behov endast om det är av privat och känslig natur. Det som vanlig anses vara av denna karaktär är den på- och avklädning som sker av kläderna närmast kroppen, såsom underkläder och byxor. Den på- och avklädning av ytterkläder och skor innefattas vanligen inte. Hjälp med kommunikation anses endast ingå i de grundläggande behoven om en assistent måste finnas tillgänglig för att kommunikation överhuvudtaget ska anses vara möjlig. Detta kan vara fallet då den funktionshindrade kommunicerar genom bilder, signaler i beteende eller ansiktsuttryck som någon utan kunskap om denne inte har möjlighet att förstå. Av det grundläggande behovet annan hjälp som förutsätter ingående kunskap om den funktionshindrade omfattas sedan 2015 endast personer med psykiska funktionshinder. Den hjälp som här innefattas är så kallad aktiv tillsyn av övervakande karaktär, vilket kan behövas antingen för att övervaka att personen tillgodoser sina andra grundläggande behov genom så kallade kvalificerade motiverings- och aktiveringsinsatser eller för att hindra den enskilde från att skada sig själv, andra eller egendom.Vid arbetet med min andra frågeställning, hur grundläggande och personliga behov förhåller sig till varandra, kom jag fram till att detta är ett hjälpbehov utöver de grundläggande behoven. För att beviljas assistans krävs att det föreligger ett hjälpbehov som innefattar de grundläggande behoven och först då kan assistans beviljas även för andra personliga behov. Det har av HFD och Försäkringskassan anförts att de behov som efter deras bedömning kan anses gå utöver de grundläggande behoven kan anses ingå i andra personliga behov. Detta innebär att även om matlagning, inköp och bestämmande av mat inte ingår i det grundläggande behovet måltid så kan en funktionshindrad beviljas assistans för detta utöver den hjälp som denne behöver med intagandet av måltiden. Från och med april 2018 är det dessutom uttryckligen reglerat i LSS att assistans för andra personliga behov avser även väntetid, beredskap och tid mellan olika hjälpbehov vid aktiviteter utanför den funktionshindrades hem.

L'assistance est la forme primitive de l'assurance. On constate actuellement la multiplication des societes de service dites d'assistance, dont l'objet est de porter une aide materielle et morale a toute personne en difficulte, notamment en cas de voyages a l'etranger. Ces societes empruntent la technique de l'assurance. Si l'assistance a bien preexiste a l'assurance, il y a aujourd'hui une renaissance de l7assistance. Celle-ci est devenue, depuis l'adoption de la directive communautaire "assistance touristique", une nouvelle branche d'assurance. Comparer l'assistance a l'assurance conduit a observer les differences de leurs regimes. Cependant, le contrat d'assistance presente les memes principaux caracteres que le contrat d'assurance; de plus, nombre de contrats d'assistance, proposes par des entreprises d'assurance, ne sont autres que des contrats d'assurance. L'etude du regime juridique de l'assurance conduit a affirmer l'identite de nature des activites d'assistance et d'assuranceAssistance is the primitive form of insurance. We may see to day the multiplication of services companies called assistance companies whose purpose is to give a material and moral aid to any people in difficulty, especially in case of travels abroad. These companies have adopted the insurance technic. If assistance has effectively preceded insurance, there is now a renewal of assistance. Assistance has become, since the adoption of the e. E. C. Directive the "touristic assistance", a new branch. To compare assistance and insurance leads to observe the differences of their schemes. However, the assistance contracts offerts the same characteristics as the insurance contract. Many of the assistance contracts proposed by the insurance companies are nothing else but insurance contracts. The survey of the juridic scheme of assistance contrives to assert the identity of nature between assistance and insurance activities

Les travaux présentés dans ce mémoire traitent du développement d'une assistance robotisée comportant un bras préhenseur (Manus®) monté sur un porteur mobile capable de suivre de façon automatique le fauteuil roulant du patient afin de mettre à la disposition de l'utilisateur le bras Manus®. La première partie de ces travaux concerne la création d'un algorithme permettant la modélisation de capteurs catadioptriques omnidirectionnels particuliers. Ils répondent à des contraintes prédéfinies permettant d'observer différents éléments de l'environnement sans déformations radiales. Dans un second temps, nous exposons deux méthodes de suivi automatique de fauteuil roulant à l'aide des seuls capteurs de vision omnidirectionnelle stéréoscopique. La méthode mise en application dans le projet permet d'effectuer un suivi d'objet suivant une méthode probabiliste basée sur le MeanShift et le CAMShift. Dans ce mémoire, nous adaptons le CAMShift de façon à travailler directement sur les images omnidirectionnelles afin d'obtenir une méthode rapide baptisée OmniCAMShift. Cette méthode comprend également une initialisation simple par soustraction d'image, prenant en compte les ombres et les sur illuminations. Le troisième point concerne l'ensemble de la navigation. Nous y traitons la cartographie, apportant ici une nouvelle méthode d'appariement robuste d'amers utilisant des capteurs omnidirectionnels stéréoscopiques. L'exploitation de ces appariements permet de construire une grille d'occupation absolue de l'environnement, et d'inclure des procédures d'évitement d'obstacle et de passage de porte automatique. Ce mémoire ayant pour caractéristique d'être fortement appliqué, une dernière partie expose l'ensemble des résultats et travaux d'ergonomie dans le cadre d'interactions homme machine liés à l'utilisation de cette assistanceThe work presented in this memory deals with the development of an aid for disabled people. This aid is the bundle of a Manus arm and a mobile robot, which is able to follow automatically the user's wheelchair. When the user wishes to use the Manus®, the mobile robot comes in front of the wheelchair and its occupant can use the Manus® arm. The first part of this work is the creation of an algorithm able to generate particular kind of omnidirectional catadioptric sensors. Those sensors allow to observe different parts of the environment without any radial deformation. In the second point, we explain two methods of automatic following of the wheelchair thanks to the sole stereoscopic omnidirectionals vision sensors. The method used in the project allows the tracking of an object using a probabilistic method based on the MeanShift and the CAMShift. In this work, we adapt the CAMShift in order to work directly on the omnidirectional images in order to get a method that we named OmniCAMShift. This method also embeds a simple initialisation of the model by subtracting images, taking into account shadows and highlights. The third point concerns the whole navigation. We deal with map generation, and we expose a new way to match the natural beacon using stereoscopic omnidirectional sensors. The use of those results enables to build an absolute occupation grid of the environment. Then we include the avoiding of obstacles and going through doors functionalities. This work has the particularity of being highly practical. A last part consequently shows the whole results and ergonomic work in the field of human-computer interface linked to the use of this aid for disabled people

Solution substitutive à la fonction parentale, la famille d'accueil revêt la teneur d'un enjeu important. Réduisant le champ de cette recherche à la seule population d'assistantes maternelles ayant atteint ou dépassé la crise du milieu de la vie, l'auteur propose de mener une étude psychologique de ces vocations tardives. La première thèse développée concerne la problématique du deuil. L'hypothèse a été de considérer l'enfant placé comme entrant dans l'organisation d'un travail de deuil qui permettrait à l'assistante maternelle de surmonter la position dépressive. La deuxième thèse développée concerne le rapport problématique à l'égard des enfants. La troisième thèse a été de considérer ces femmes comme reproduisant leur propre roman familial en accédant à cette profession. Tout le long de cette recherche, l'auteur a voulu dégager les motivations sous-jacentes à la décision de prendre en garde des enfants confiés au service de l'aide sociale à l'enfance par décision judiciaireAs a solution to the problem of finding parental substitutes, foster parents assume an important role. Confining the scope of this research to foster mothers who have either reached or passed the mid-life crisis, the writer intends to carry out a psychological study of these late vocations. The first argument put forward concerns the question of bereavement. The hypothesis considered is that the child placed in care (with foster parents) becomes a part of the recovery process for the bereaved foster mother, allowing her to overcome the "depressive period". The second argument concerns the problematic relationship of the foster mother with the children. The third argument considers the possibility that these women reproduce their own "family story" by adopting this profession. Throughout this research, the writer has sought to bring out the motives underlying the decision to look after these children who have been place in the care of the children's department of the social services by the courts

This project evaluates the effectiveness and impact of a feeding assistance programme ‘Making Meal Times Better for those with a Dementia’ (MMB) supported by five sixty minute health professional led support forums as compared to a three hour MMB standalone version and control conditions for health care assistants (HCAs) working with residents with a dementia and oral feeding difficulties. Outcomes were evaluated for 90 participating health care assistants and 451 observed meal times across three nursing homes. Measures of staff knowledge, competency, attitudes and daily care practices were measured using self completion questionnaires alongside observations of the quality of and adequacy of mealtime feeding assistance pre- and five months post intervention, using purposive sampling. HCAs who participated in support forums maintained significantly better knowledge and competency scores five months following training compared to those who received the stand-alone three hour MMB training programme and control conditions. Observations of mealtimes revealed that the nursing home exposed to greatest duration of training demonstrated most improvement in the provision of quality feeding assistance: actively identifying and providing targeted feeding assistance to those residents deemed at risk of malnutrition and relocating more residents into the communal dining room. Beneficial changes were accompanied by a significant reduction in social stimulation. Control conditions demonstrated several changes in feeding behaviours which may be attributed to attempts to increase oral intake without sufficient training. Training increased the food consumption of those residents at risk of malnutrition but did not increase food consumption overall or the high levels of stress and guilt experienced by HCAs. Lack of social cueing and less than five minutes of feeding assistance were correlated with increased risk of malnutrition across nursing homes. A paucity of HCA documentation of oral intake in medical records suggests an organisational barrier to the translation of HCA knowledge to the wider healthcare team.

They are a primary instrument for advancing U.S. national interests, enhancing global stability, expanding economic opportunities, and promoting American democratic values. From 2004 through 2010, the United States donated more than $16 billion in economic assistance to countries in the Western Hemisphere. Some ask why the United States spends so much money abroad on humanitarian programs and infrastructure investments in developing states. To address this question, this thesis looks at Colombia and Mexico, both of which are of crucial strategic importance to the United States. Under Plan Colombia (20002006), U.S. economic assistance and staunch political will enabled Colombia to improve from 14th (2005) to 57th (2013) on the Failed State Index scale. As a result, Colombia has also emerged as a stronger U.S. partner in the Western Hemisphere. The Colombian experience was historically specific, but lessons can be extracted for Mexico, even though its history and relationship with Washington is very different. In particular, the recent Merida Initiative (Plan Mexico; 2008present) can benefit immensely from being carefully evaluated in light of the earlier success of Plan Colombia.

Purpose: The aim is to investigate the mechanisms behind the destructive entrepreneurship in the assistance industry. Method: To investigate the destructive entrepreneurship in the assistance industry, we conducted a qualitative study in the form of semi-structured questions. In total, we interviewed four authorities and an employer organization. Theory: Theoretical framework: The study is based on Baumol's (1990) theory of productive, unproductive and destructive entrepreneurship and rent-seeking by Murphy et al (1991), but the study's principal theory that we have chosen to apply is the routine activity theory of Cohen & Felson (1979) that describes three elements that must come together in order for a crime to be committed. Conclusions and discussion: Our study shows that it is clear that there is both fraud and abuse within the assistance allowance, which can be done in different ways. Some users simulate their illness that they exaggerate their need for assistance. Some assistance providers have abused the compensation by paying lower wages and empty false wages etc. The study showed that there also exists a type of human trafficking. The fraud/abuse includes millions of kroner and it requires several people to accomplish the embezzlement. The most common form in which cheating occurs is limited but it is suspected that the abuse occurs in all forms of assistance other than the cooperative assistance form. The assistance industry is not in a position of being undermined; however, compensation levels may be slightly compressed.Syfte: Syftet är att utreda mekanismerna bakom det destruktiva entreprenörskapet i assistansbranschen. Metod: För att undersöka det destruktiva entreprenörskapet i assistansbranschen har vi genomfört en kvalitativ undersökning i form av semistrukturerade intervjuer. Totalt intervjuade vi fyra myndigheter och en arbetsgivareorganisation. Teoretisk referensram: Studien utgår ifrån Baumols (1990) teori om produktivt, improduktivt samt destruktivt entreprenörskap och privilegiejaktsteorin av Murphy med flera (1991), men studiens huvudteori som vi har valt att tillämpa är rutinaktivitetsteorin av Cohen & Felson (1979) som beskriver tre förutsättningar som måste sammanstråla för att ett brott ska kunna begås. Slutsats och Diskussion: Vår studie visar att det står klart att det förekommer både fusk och missbruk inom assistansersättningen vilket kan utföras på olika sätt. Från att vissa brukare simulerar sin sjukdom till att de överdriver sina assistansbehov. Vissa assistansanordnare har missbrukat ersättningen genom att betala lägre löner och t.o.m. falska löner mm. Studien visade att det också förekommer en typ av människohandel. Fusket/missbruket handlar om miljonbelopp och det krävs ett nätverk av personer för att åstadkomma förskingringen. Den vanligaste formen där fusket förekommer är aktiebolag men det misstänks att missbruket förekommer i alla assistansformerna utom den kooperativa assistansformen. Assistansbranschen riskerar dock inte att undermineras däremot kan ersättningsnivåerna komma att pressas något.

In this thesis a simple and low-cost aided inertial navigation system is presented which can be used to automate underwater search operations. The system is designed and implemented to be compatible with a VideoRay Pro 3 tethered mini-ROV. Inertial-, compass- and pressure measurements are collected with a dedicated embedded system and transferred to the surface for processing. System states are estimated, compared against a user specified pattern and used to generate path-following control inputs. The system is tested on a small scale and the results obtained through camera-based measurements show acceptable performance for short time intervals.

As part of a Naval Postgraduate School's capstone project in Systems Engineering, the project team from Cohort 311-101O of the Naval Postgraduate School (NPS), performed a Systems Engineering analysis and verified the analysis with the acquisition and partial testing of the Humanitarian Assistance Shelter System (HASS). The HASS was developed in response to a need for a rapidly deployable mid-term shelter solution for disaster victims. There exists immediate shelter solutions for the victims, yet there is no transitional shelter available for the period between the demise of the immediate shelter and acquisition of permanent housing. For example, the displaced Haiti earthquake victims are still living in tents more than a year after the disaster has struck. This report documents the disciplined Systems Engineering approach used to determine the requirements, trade-offs, cost-effective solution, and testing required of the solution to fulfill the HASS stakeholders needs. Due to time constraint, partial testing on the HASS components was done with findings documented as well as recommendation for further testing and future work.

This thesis presents three reluctance machines with flux assistance. These machines provide alternative novel geometries that provide high efficiencies with a reduction in the ampere turns in the armature windings for torque production, lowering armature winding switching losses and reducing the power electronic rating. The Dual Stack Variable Reluctance Machine is a switched reluctance variant of the homopolar inductor alternator topology. The Single Stack Variable Reluctance Machine is a simplification of the Dual Stack machine. Both machines use a toroidal field winding to provide additional flux. The methods of connecting armature coils on each stator pole to utilise the armature flux and the choice of power electronic circuitry are important. Testing shows that such machines favour unipolar excitation with single coil per pole for the armature windings. Use of the field winding in series with the armature windings improves torque production. The Dual Stack Variable Reluctance Machine can have the mechanical angular displacement between the two stator stacks varied to provide an improved back emf waveshape for smoother torque production. The Single Stack Variable Reluctance Machine has parasitic and axial air gaps that pose interesting design issues (e.g. end thrust). Magnets can be placed in steel sections where flux is unidirectional. An ideal candidate for magnet insertion is the Flux Switching Motor. A Permanent Magnet Flux Switching Motor has been built that replaces the field windings with ferrite magnets. The Permanent Magnet Flux Switching Motor achieves efficiencies of over 80%. It adds no additional cost to the fan application as cost savings in lower temperature rated thermoplastics offsets the cost of magnets. A prototyping circuit incorporating a novel micro-processor program to alter the commutation timings as the machine operates has been designed to allow fast optimisation of each machine for minimum input power.

Parallelement, l'enseignement du travail social peut acceder a une scientificite accrue, et la technologie assistancielle qui en decoule peut remplacer sans conflit majeur l'anomie organisationnelle (analysee en detail) des services d'action socialeSocial relief phenomenons, so called social work to day (1,6 % of g. N. P. ) have produced very complex historic evolution and theorethic discussions in the field of social sciences. Two ones are analysed in the thesis. However social relief phenomenon can be defined as an action on the two opposite terms of contribution retribution of beneficiaries. Thus, under specific conditions, major social conflicts or deficits can be avoided by the community. Such conceptualisation allows building an evaluative trilogy developping assessment on effects, action modalities and cost-benefit ratio about social relief phenomenon. Hypothesis are positively tested by three empirical and genuine researchs. Critical uncertainity of assistance organisations is reduced by this operationalization. This allows to consider that general attitude of cultural out-playing among social workers may be replaced by a socioeconomic cooperation with environmental background. Moreover, teaching of social work may be strongly implemented, and an assistancial technology based on, may break up with organisational anomy (analysed with details) of social welfare services

Fahrerassistenzsysteme werden zunehmend in Fahrzeuge eingebaut mit dem Ziel, den Fahrer beim Fahren zu unterstützen, Fahrfehler zu vermeiden und damit die Fahrsicherheit zu erhöhen. Derzeit sind häufig Systeme im Einsatz, die den Fahrer vor bestimmten Sicherheitsrisiken warnen (z.B. vor einem unbeabsichtigten Verlassen der Fahrspur). Der Trend geht aber hin zu Systemen, die stärker ins Fahrgeschehen eingreifen und somit Teile der Fahraufgabe automatisieren (z.B. selbständig die Spurhaltung des Fahrzeugs übernehmen). Aus der Forschung zur Mensch-Maschine Interaktion ist jedoch bekannt, dass Automatisierung nicht zwangsläufig zur Erhöhung von Sicherheit führt, sondern dass sie vielmehr auch unerwünschte Nebeneffekte für Performanz und Sicherheit mit sich bringen kann in dem Maße, wie Menschen an die veränderten Aufgabenanforderungen adaptieren. Im Straßenverkehr wird insbesondere befürchtet, dass Fahrer sich zu stark auf Fahrerassistenzsysteme verlassen, sich teilweise aus der Fahraufgabe zurückziehen („abschalten“) und ihre Aufmerksamkeit fahrfremden Dingen widmen. Dies kann unter Umständen dazu führen, dass Fahrer im Falle von Systemfehlern oder –ausfällen nicht mehr in der Lage sind rechtzeitig und angemessen einzugreifen bzw. die Kontrolle über das Fahrzeug zu übernehmen. Ziel der Dissertation war es zu untersuchen, inwieweit sich die Involviertheit von Fahrern in die Fahraufgabe verändert je stärker sie durch ein Assistenzsystem unterstützt werden (d.h., je stärker das System Teile der Fahraufgabe automatisiert). Um dies zu untersuchen wurden zwei theoretische Konzepte herangezogen: a) das Verlassen der Fahrer (auf ein System) und b) das Situationsbewusstsein der Fahrer. Basierend auf einer umfassenden Analyse der Forschungsliteratur zum Thema Automatisierung wurde ein theoretisches Rahmenmodell entwickelt, welches Veränderungen in der Involviertheit des Fahrers in die Fahraufgabe auf menschliche Adaptationsprozesse auf verschiedenen Ebenen zurückführt, die sich in Folge der veränderten Aufgabenanforderungen durch zunehmende Automatisierung ergeben. Dazu zählen Veränderungen in Einstellungen, sowie in kognitiven, energetischen, und motivationalen Prozessen. Um Veränderungen in diesen Prozessen zu untersuchen, wurde eine Vielzahl an objektiven und subjektiven Maßen erhoben. Hauptgegenstand der Dissertation ist eine umfangreiche Fahrsimulatorstudie im Fahrsimulator mit Bewegungsplattform bei VTI (Swedish National Road and Transport Research Institute) in Linköping, Schweden. Dabei kamen zwei Querführungsassistenzsysteme (ein Heading Control System und ein Lane Departure Warning System) zum Einsatz, die den Fahrer in unterschiedlichem Maße bei der Spurhaltung unterstützten. Im Gegensatz zu einem Großteil der bisherigen Studien wurden prozessorientierte Performanzmaße zur Erfassung des Verlassens der Fahrer auf die Assistenzsysteme und des Situationsbewusstseins der Fahrer verwendet. Das Verlassen der Fahrer auf die Querführungsassistenzsysteme wurde durch Blickverhaltensmaße über die Bereitschaft der Fahrer erfasst, ihre visuelle Aufmerksamkeit von der Straße ab hin zu einer Zweitaufgabe im Fahrzeuginnenraum zu wenden. Zur Messung des Situationsbewusstseins der Fahrer wurden Fahrverhaltensmaße herangezogen welche als Indikator für die Schnelligkeit und Abruptheit der Reaktionen der Fahrer auf unerwartete kritische Fahrsituationen dienten. Ein Hauptbefund der Dissertation war, dass die Fahrer sich signifikant im Ausmaß ihres Verlassens auf einen hohen Grad an Assistenz unterschieden. Diese interindividuelle Varianz im Verlassen der Fahrer auf einen hohen Grad an Assistenz konnte am besten durch das Vertrauen der Fahrer in das Querführungsassistenzsystem und ihr Aktivierungsniveau erklärt werden: Je höher das Vertrauen der Fahrer in das System und je geringer ihr Aktivierungsniveau, desto stärker verließen sie sich auf das System. Individuelle Fahrermerkmale (Fahrstil) erklärten einen signifikanten Anteil der Varianz im Vertrauen der Fahrer in die Spurhalteassistenzsysteme. (ersetzt wegen neuem Herausgeber)Advanced driver assistance systems are increasingly built in vehicles with the aim to support drivers while driving, to reduce driver errors and thereby to increase traffic safety. At present, these systems are often designed to warn drivers of specific safety risks (e.g., of an imminent departure from the driving lane). However, there is a trend towards systems that more strongly intervene in driving and that hence, automate parts of the driving task (e.g., autonomously keep the vehicle within the driving lane). However, research on human-machine interaction has shown that automation does not necessarily increase safety, but that it may also lead to unanticipated side effects on performance and safety to the extent that humans adapt to the changing task demands. A major concern in road traffic is that drivers rely too heavily on driver assistance systems, become less actively involved in the driving task, and divert their attention to things unrelated to driving. Thus, in the case of system malfunctions or failures, drivers possibly may not be prepared to intervene timely and accordingly and to regain control over the vehicle, respectively. The aim of this dissertation was to investigate changes in drivers’ active engagement in the driving task as a function of the degree to which they are supported by a driver assistance system (i.e., as a function of the degree to which the system automates the driving task). Drivers’ active task engagement was studied by referring to two theoretical concepts: a) drivers’ reliance (on a system) and b) drivers’ situation awareness. Based on an extensive review of previous research on automation, a conceptual theoretical framework was developed that links changes in operators’ active task engagement to human adaptation processes on different levels in response to the changing task demands due to automation. Among them are changes in human attitudes as well as in cognitive, motivational and energetic processes. In order to determine the relative influence of these processes, a range of objective and subjective measures was collected. The essential part of the dissertation is an extensive driving simulator study in an advanced moving-base driving simulator at VTI (Swedish National Road and Transport Research Institute) in Linköping, Sweden. Two lateral support systems (a Heading Control system and a Lane Departure Warning system) were implemented which assisted drivers to different degrees in lane keeping. Contrary to most previous automation studies, drivers’ reliance on the lane keeping assistance systems and their situation awareness were studied by using process-oriented performance-based measures. Drivers’ reliance on the lane keeping assistance systems was assessed by eye glance behaviour measures indicating drivers’ preparedness to allocate their visual attention away from the road scene to an in-vehicle secondary task. Drivers’ situation awareness was assessed by behavioural measures of the latency and magnitude of drivers’ initial reactions to unexpected critical driving situations. A major finding of the study was that drivers differed significantly in their reliance on a high level of lane keeping assistance. This interindividual variance in drivers’ reliance on higher-level assistance could be best explained by drivers’ trust in the system and their energetic arousal: The greater drivers’ trust in the system and the lower their arousal, the more did they rely on the system. Individual driver variables (driving style) explained a significant proportion of the variance in drivers’ trust in the lane keeping assistance systems. (replaced because a new publisher)

Foreign aid has been a signal component of United States foreign policy since the creation of the Marshall Plan. Since that time, as new requirements emerged, numerous foreign aid programs and initiatives were created and subsequently piecemealed together under various U.S. agencies. The confluence of programs, initiatives, and agencies has created a confusing and overly bureaucratized environment for expending funds in an effort to support the democratization and modernization of other countries. This study examines U.S. aid provided to Ukraine and Georgia to determine if they have progressed toward Westernized defense and military structures, in accordance with their stated national goals, within the realm of logistics. The question is whether U.S. security aid in these states has helped to achieve these goals. Addressing this question, this thesis proposes a hierarchal construct with differing assessment criteria based on how and where U.S. aid is applied. In the end, this analysis shows that U.S. aid and assistance programs and funds have assisted both Ukraine and Georgia with their modernization efforts. However, U.S. policy makers and policy implementers need to consideration alternative and new methods to accurately assess how well those funds are spent in-line with U.S. foreign policy goals.

El moviment és un atribut perceptiu del cervell humà molt important. La percepció visual que fa el cervell del moviment és el procés d’inferir la velocitat i direcció dels elements d’un escenari mitjançant entrades visuals. Anàlogament, la visió per computador s’assisteix mitjançant informació del moviment de l’escena. En visió per computador, la detecció de moviment és útil per a resoldre problemes com per exemple segmentació, estimació de la profunditat, estimació de l’estructura a partir del moviment, compressió de dades o navegació entre d’altres. Aquests problemes són comuns a diferents aplicacions, com ara vídeo vigilància, navegació de robots i sistemes avançats d’assistència a la conducció (Advanced Driver Assistance Systems, ADAS). Una de les tècniques més utilitzades per a detectar moviment, és el càlcul d’optical flow. El treball tractat en aquesta tesi pretén que les formulacions d’optical flow siguin més apropiades als requeriments i condicions dels escenaris de conducció. En aquest context, es proposa una nova representació de l’espai-variant anomenada representació reverse log-polar, i es demostra que, quan s’utilitza per a ADAS, té un rendiment millor que la tradicional representació log-polar. La representació espai-variant redueix la quantitat de dades necessàries que han de ser processades. Una altra contribució important està relacionada amb l’anàlisi de la influència de les característiques específiques d’escenaris de conducció per a la precisió de l’optical flow. S’han considerat característiques tals com la velocitat del vehicle i la textura de la carretera. D’aquest estudi s’infereix que, el pes del terme de regularització s’ha d’adaptar segons una mesura d’error i per a diferents velocitats i textures de la carretera. També es mostra que la representació polar d’optical flow funciona molt millor per a escenaris de conducció on el moviment principal són translacions. Degut als requeriments d’aquest estudi, i per la manca de bases de dades es presenta una nova base de dades sintètica que conté: i) seqüències amb diferents velocitats i textures en un escenari urbà; ii) seqüències amb moviments complexos de la càmera col·locada al vehicle; i iii) seqüències amb altres vehicles en moviment dintre la mateixa escena. L’optical flow corresponent a cada seqüència s’obté mitjançant la tècnica de ray-tracing. A més a més, es presenten algunes aplicacions per a optical flow en escenaris ADAS. Per començar, proposem una tècnica robusta basada en RANSAC per estimar la línia de l’horitzó. Després, presentem una estimació de l’egomotion per a comparar la representació espai-variant proposada amb les representacions clàssiques. Com a contribució final, es proposa una modificació del terme de regularització que millora notablement els resultats per a aplicacions d’ADAS. Aquesta adaptació s’avalua mitjançant tècniques d’optical flow d’última generació. Els experiments realitzats amb una base de dades pública (KITTI) validen els avantatges d’utilitzar la modificació proposada.La percepción del movimiento es uno de los más importantes atributos del cerebro humano. La percepción visual del movimiento consiste en inferir velocidad y dirección de los elementos móviles que interactúan en una escena, mediante la interpretación de diferentes entradas visuales. Análogamente, la visión por computador hace uso de la información del movimiento en la escena. La detección de movimiento en visión por computador es útil para resolver problemas tales como: segmentación, estimación de profundidad, compresión, navegación, entre otros. Estos problemas son comunes en distintas aplicaciones, por ejemplo: video vigilancia, navegación de robots y sistemas avanzados de asistencia a la conducción (ADAS). Una de las técnicas más utilizadas para detectar movimiento es la estimación del flujo óptico. El trabajo abordado en esta tesis busca formulaciones del flujo óptico más adecuadas a las necesidades y condiciones de los escenarios de conducción. En este contexto, se propuso una novedosa representación del espacio, llamada representación inversa log-polar, la cual se demuestra que tiene un desempeño mejor que la tradicional representación logpolar para aplicaciones ADAS. Las representaciones de espacio-variante reducen la cantidad de datos a ser procesados. Otra contribución importante está relacionada con el análisis de la influencia de las características específicas de los escenarios de conducción en la precisión del flujo óptico estimado. Características tales como la velocidad del vehículo y la textura de la carretera son consideradas en el estudio. De este estudio, se infiere que el peso del término de regularización tiene que ser adaptado de acuerdo con la medida de error requerida y para diferentes velocidades y texturas de la carretera. También se concluye que la representación polar del flujo óptico es la más apropiada en escenarios de conducción, donde el movimiento predominante es la translación. Debido a las exigencias de tal estudio, y por falta de las bases de datos necesarias, se presenta un nuevo conjunto de datos sintéticos el cual contiene: i) secuencias de diferentes velocidades y texturas en un escenario urbano; ii) secuencias con movimientos complejos de la cámara dispuesta en el vehículo; y iii) secuencias con otros vehículos en movimiento en la escena. El flujo óptico correspondiente a cada secuencia es obtenido mediante una técnica de ray-tracing. Adicionalmente, se presentan algunas aplicaciones de flujo óptico en ADAS. Primeramente se propone una técnica robusta basada en RANSAC para estimar la línea de horizonte. Seguidamente se presenta una estimación del egomotion para comparar la representación de espacio-variante propuesta con los esquemas clásicos. Como contribución final, se propone una modificación en el término de regularización que mejora notablemente los resultados en las aplicaciones ADAS. Los resultados experimentales en una base de datos pública (KITTI) validan las ventajas de la utilización de la modificación propuesta.
Motion perception is one of the most important attributes of the human brain. Visual motion perception consists in inferring speed and direction of elements in a scene based on visual inputs. Analogously, computer vision is assisted by motion cues in the scene. Motion detection in computer vision is useful in solving problems such as segmentation, depth from motion, structure from motion, compression, navigation and many others. These problems are common in several applications, for instance, video surveillance, robot navigation and advanced driver assistance systems (ADAS). One of the most widely used techniques for motion detection is the optical flow estimation. The work in this thesis attempts to make optical flow suitable for the requirements and conditions of driving scenarios. In this context, a novel space-variant representation called reverse log-polar representation is proposed that is shown to be better than the traditional log-polar space-variant representation for ADAS. The space-variant representations reduce the amount of data to be processed. Another major contribution in this research is related to the analysis of the influence of specific characteristics from driving scenarios on the optical flow accuracy. Characteristics such as vehicle speed and road texture are considered in the aforementioned analysis. From this study, it is inferred that the regularization weight has to be adapted according to the required error measure and for different speeds and road textures. It is also shown that polar represented optical flow suits driving scenarios where predominant motion is translation. Due to the requirements of such a study and by the lack of needed datasets a new synthetic dataset is presented; it contains: i) sequences of different speeds and road textures in an urban scenario; ii) sequences with complex motion of an on-board camera; and iii) sequences with additional moving vehicles in the scene. The ground-truth optical flow is generated by the ray-tracing technique. Further, few applications of optical flow in ADAS are shown. Firstly, a robust RANSAC based technique to estimate horizon line is proposed. Then, an egomotion estimation is presented to compare the proposed space-variant representation with the classical one. As a final contribution, a modification in the regularization term is proposed that notably improves the results in the ADAS applications. This adaptation is evaluated using a state of the art optical flow technique. The experiments on a public dataset (KITTI) validate the advantages of using the proposed modification.

La chirurgie laparoscopique conventionnelle apporte des avantages aux patients mais pose des défis aux chirurgiens. Utiliser le robot permet de surmonter certaines des difficultés. Nous utilisons ici le concept de comanipulation, où un bras robotique sert de comanipulateur et génère des champs de force pour aider les chirurgiens. Pour implémenter des fonctions telles que la compensation de la gravité de l’instrument, il est utile de connaître la position du trocart en temps réel par rapport à la base du robot. Nous proposons un algorithme de détection et localisation de trocarts, basé sur la méthode du moins carré. Des expériences in vitro et in vivo valident son efficacité. Considérant des caractéristiques de la chirurgie laparoscopique, i.e., de l’espace de travail grand et de la difficulté de planifier le geste, des champs visqueux sont utilisés. Afin de s’adapter aux mouvements différents, nous utilisons une loi de commande de viscosité variable. Cependant, elle rencontre un problème d’instabilité, qui est analysé théoriquement et expérimentalement. Une solution d’ajout d’un filtre passe-bas de premier ordre est proposée, dont l’efficacité est mise en évidence par une expérience de ciblage point à point. Avec la position du trocart connue, nous pouvons établir «le modèle de levier», une formule décrivant la relation entre les vitesses et les forces appliquées à différents points de l’instrument. Ceci permet de mettre en œuvre une loi de commande de viscosité sans utiliser de signaux bruités, au point de centre de la poignée ou la pointe de l’instrument. Une expérience est menée pour comparer l’influence de la loi de commande sur les comportements de mouvement humainTraditional laparoscopic surgery brings advantages to patients but poses challenges to surgeons. The introduction of robots into surgical procedures overcomes some of the difficulties. In this work, we use the concept of comanipulation, where a 7-joint serial robotic arm serves as a comanipulator and generates force fields to assist surgeons.In order to implement functions like instrument gravity compensation, identifying real-time trocar position with respect to robot base is a prerequisite. Instead of obtaining trocar information from the registration step, we propose a robust trocar detection and localization algorithm based on least square method. Both in-vitro and in-vivo experiments validate its efficiency.Considering the characteristics of laparoscopic surgery, i.e., relatively large workspace and flexible operating objects, viscous fields are employed. To better adapt to different motion, we use a variable viscosity controller. However, this controller encounters an instability problem, which is analyzed both theoretically and experimentally. A solution of adding a first order low pass filter is proposed to slow down the variation of the viscosity coefficient, whose efficiency is evidenced by a point-to-point targeting experiment.With real-time trocar position known, the “lever model”, a formula describing therelationship of the velocities and forces of different instrument points, can be established. This allows implementing viscosity controller without using noisy signals at the center points of instrument handle and tip. Another point-to-point movement experiment is conducted to compare the features of the controller influence on human motion behaviors

Humanitarian assistance is of growing importance to the United States and the Department of Defense's strategic objectives. Thus, United States combatant commands increasingly rely on humanitarian assistance cargo transportation programs to deliver materiel to people in need in their areas of responsibility. This report analyzes the options available to these commands in seeking humanitarian assistance cargo transportation. The report offers a description of current operations, with a specific focus on the European area of responsibility, where these programs have had limited activity. The analysis reaches the following conclusions: (1) currently no transportation program exists that focuses on providing a quality of service to combatant commands and humanitarian assistance transportation needs, (2) legal, fiscal, and operational mechanisms exist and are outlined to create such a program, and (3) exclusively space-available transportation is generally insufficient for providing the quality of service that may be required for relationship-building through humanitarian assistance cargo transportation, and contract shipping may be necessary. These conclusions are placed in the context of current humanitarian assistance operations, and relevant operational considerations are highlighted throughout the report. The analysis is based on both a quantitative model of transportation, as well as detailed conversations with humanitarian assistance personnel throughout key Department of Defense organizations.

The drive to reduce costs and to ensure that ports can stay open to the maximum extent in all weathers has given impetus to the search for more flexible vessel traffic management; something that current advances in technology make it possible to contemplate. Various issues pose a significant challenge to implementation, including the inherent conservatism of the maritime community. Nonetheless, aspects of potential new services are already in regualr use. Remote pilotage is a detectable strand in EU research thinking and the port of Rotterdam is preparing for its all weather implementation. First the issues involved were established by means of a literature search followed by a series of structured interviews and a questionnaire. the results were analysed, leading to a body of results that can be used by those seeking to make decisions in this area of maritime operations. A comparison with Air Traffic Management concluded that there would be merit in adopting some of its philosophy and procedures. specific focus was then given to establishing, by means of a questionnaire, a generic set of indicators by which it can be decided whether specific vessels quality for a given new service. Throughout the research qualitative data was sought from highly qualified professionals. Two new services are proposed; remote pilotage and enhanced navigation assistance. In the hierarchy of services they fit between the provision of an on board pilot and those currently provided by a VTS. Working definitions of both services have been established. The required technology is either available or can be seen to be a realistic prospect. AIS has emerged as a key enabling technology and the exchange of passage plans will be important. However,technology alone will not suffice to make change practible. The non-technological issues are more intractable but capable of solution. Progress, if realised, can be expected to be slow; the current assessment for the spread of remote pilotage is 10-15 years. A case cannot be made for the implementation of remoter pilotage or enhanced navigation assistance on the grounds of improved safety; an acceptable level of safety must be assumed to exist. There is also a need for the appropriate legislative framework to be in place and the issue of liability to be resolved. Ultimately the prime requirement for successful implementation is the realisation of a commercial benefit to both a port and the ship owner.

Previous low cost systems of navigational assistance for disabled wheelchair users have provided little more than simple obstacle and collision avoidance, or follow a pre-defined fixed route defined by a white line or a buried wire. Other research has used complex high cost multi-sensor mode systems closely resembling industrial, military or space exploration applications. These systems used natural features or artificial beacons to produce accurate maps of the operating environments. The progress of the vehicle is monitored and corrected using multisensor techniques such as vision cameras, odometry and triangulation from beacons located in the environment. Such systems have required modification of the operating environment and have resulted in a fully autonomous vehicle providing little or no overall control by the user. Whilst proving the technical feasibilty their cost and complexity has not resulted in practical and affordable solutions for the wheelchair user. The purpose of the present study was to bridge the gap between these two previous areas of research and to provide navigational assistance at an affordable cost. Low cost ultrasonic sensors enabled a wheelchair to operate in an unknown (i. e. previously unmapped) environment whilst leaving the user in overall control. Hardware modifications to a commercial powered wheelchair enabled data from ultrasonic arrays and the user's joystick to be interrogated and mixed by a computer to provide appropriate signals for the wheelchair drive motors. A simulation program was created to interpret the sensor signals that would be generated from the various conditions likely to be encountered by a wheelchair and to develop the various control strategies. The simulation was able to differentiate between the various environmental conditions and select the appropriate action using the newly created control algorithms. The sensor data interpretation modules together with the control algorithms, from the simulation, were incorporated into a practical system for controlling the wheelchair. In tests data from the sensors was used to detect and evaluate localised changes in the environment and used to determine appropriate signals for the drive wheel motors. In the tests it was found that the wheelchair controller and the geometry of the wheelchair resulted in a degradation of the expected wheelchair response. This was overcome in two ways: firstly by modifying the control algorithm and secondly by changing the wheelchair geometry.

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIROA notória complexidade inerente ao processo de KDD - Descoberta de Conhecimento em Bases de Dados - decorre essencialmente de aspectos relacionados ao controle e à condução deste processo (Fayyad et al., 1996b; Hellerstein et al., 1999). De uma maneira geral, estes aspectos envolvem dificuldades em perceber inúmeros fatos cuja origem e os níveis de detalhe são os mais diversos e difusos, em interpretar adequadamente estes fatos, em conjugar dinamicamente tais interpretações e em decidir que ações devem ser realizadas de forma a procurar obter bons resultados. Como identificar precisamente os objetivos do processo, como escolher dentre os inúmeros algoritmos de mineração e de pré-processamento de dados existentes e, sobretudo, como utilizar adequadamente os algoritmos escolhidos em cada situação são alguns exemplos das complexas e recorrentes questões na condução de processos de KDD. Cabe ao analista humano a árdua tarefa de orientar a execução de processos de KDD. Para tanto, diante de cada cenário, o homem utiliza sua experiência anterior, seus conhecimentos e sua intuição para interpretar e combinar os fatos de forma a decidir qual a estratégia a ser adotada (Fayyad et al., 1996a, b; Wirth et al., 1998). Embora reconhecidamente úteis e desejáveis, são poucas as alternativas computacionais existentes voltadas a auxiliar o homem na condução do processo de KDD (Engels, 1996; Amant e Cohen, 1997; Livingston, 2001; Bernstein et al., 2002; Brazdil et al., 2003). Aliado ao exposto acima, a demanda por aplicações de KDD em diversas áreas vem crescendo de forma muito acentuada nos últimos anos (Buchanan, 2000). É muito comum não existirem profissionais com experiência em KDD disponíveis para atender a esta crescente demanda (Piatetsky-Shapiro, 1999). Neste contexto, a criação de ferramentas inteligentes que auxiliem o homem no controle do processo de KDD se mostra ainda mais oportuna (Brachman e Anand, 1996; Mitchell, 1997). Assim sendo, esta tese teve como objetivos pesquisar, propor, desenvolver e avaliar uma Máquina de Assistência Inteligente à Orientação do Processo de KDD que possa ser utilizada, fundamentalmente, como instrumento didático voltado à formação de profissionais especializados na área da Descoberta de Conhecimento em Bases de Dados. A máquina proposta foi formalizada com base na Teoria do Planejamento para Resolução de Problemas (Russell e Norvig, 1995) da Inteligência Artificial e implementada a partir da integração de funções de assistência utilizadas em diferentes níveis de controle do processo de KDD: Definição de Objetivos, Planejamento de Ações de KDD, Execução dos Planos de Ações de KDD e Aquisição e Formalização do Conhecimento. A Assistência à Definição de Objetivos tem como meta auxiliar o homem na identificação de tarefas de KDD cuja execução seja potencialmente viável em aplicações de KDD. Esta assistência foi inspirada na percepção de um certo tipo de semelhança no nível intensional apresentado entre determinados bancos de dados. Tal percepção auxilia na prospecção do tipo de conhecimento a ser procurado, uma vez que conjuntos de dados com estruturas similares tendem a despertar interesses similares mesmo em aplicações de KDD distintas. Conceitos da Teoria da Equivalência entre Atributos de Bancos de Dados (Larson et al., 1989) viabilizam a utilização de uma estrutura comum na qual qualquer base de dados pode ser representada. Desta forma, bases de dados, ao serem representadas na nova estrutura, podem ser mapeadas em tarefas de KDD, compatíveis com tal estrutura. Conceitos de Espaços Topológicos (Lipschutz, 1979) e recursos de Redes Neurais Artificiais (Haykin, 1999) são utilizados para viabilizar os mapeamentos entre padrões heterogêneos. Uma vez definidos os objetivos em uma aplicação de KDD, decisões sobre como tais objetivos podem ser alcançados se tornam nece
Generally speaking, such aspects involve difficulties in perceiving innumerable facts whose origin and levels of detail are highly diverse and diffused, in adequately interpreting these facts, in dynamically conjugating such interpretations, and in deciding which actions must be performed in order to obtain good results. How are the objectives of the process to be identified in a precise manner? How is one among the countless existing data mining and preprocessing algorithms to be selected? And most importantly, how can the selected algorithms be put to suitable use in each different situation? These are but a few examples of the complex and recurrent questions that are posed when KDD processes are performed. Human analysts must cope with the arduous task of orienting the execution of KDD processes. To this end, in face of each different scenario, humans resort to their previous experiences, their knowledge, and their intuition in order to interpret and combine the facts and therefore be able to decide on the strategy to be adopted (Fayyad et al., 1996a, b; Wirth et al., 1998). Although the existing computational alternatives have proved to be useful and desirable, few of them are designed to help humans to perform KDD processes (Engels, 1996; Amant and Cohen, 1997; Livingston, 2001; Bernstein et al., 2002; Brazdil et al., 2003). In association with the above-mentioned fact, the demand for KDD applications in several different areas has increased dramatically in the past few years (Buchanan, 2000). Quite commonly, the number of available practitioners with experience in KDD is not sufficient to satisfy this growing demand (Piatetsky-Shapiro, 1999). Within such a context, the creation of intelligent tools that aim to assist humans in controlling KDD processes proves to be even more opportune (Brachman and Anand, 1996; Mitchell, 1997). Such being the case, the objectives of this thesis were to investigate, propose, develop, and evaluate an Intelligent Machine for KDD-Process Orientation that is basically intended to serve as a teaching tool to be used in professional specialization courses in the area of Knowledge Discovery in Databases. The basis for formalization of the proposed machine was the Planning Theory for Problem-Solving (Russell and Norvig, 1995) in Artificial Intelligence. Its implementation was based on the integration of assistance functions that are used at different KDD process control levels: Goal Definition, KDD Action-Planning, KDD Action Plan Execution, and Knowledge Acquisition and Formalization. The Goal Definition Assistant aims to assist humans in identifying KDD tasks that are potentially executable in KDD applications. This assistant was inspired by the detection of a certain type of similarity between the intensional levels presented by certain databases. The observation of this fact helps humans to mine the type of knowledge that must be discovered since data sets with similar structures tend to arouse similar interests even in distinct KDD applications. Concepts from the Theory of Attribute Equivalence in Databases (Larson et al., 1989) make it possible to use a common structure in which any database may be represented. In this manner, when databases are represented in the new structure, it is possible to map them into KDD tasks that are compatible with such a structure. Topological space concepts and ANN resources as described in Topological Spaces (Lipschutz, 1979) and Artificial Neural Nets (Haykin, 1999) have been employed so as to allow mapping between heterogeneous patterns. After the goals have been defined in a KDD application, it is necessary to decide how such goals are to be achieved. The first step involves selecting the most appropriate data mining algorithm for the problem at hand. The KDD Action-Planning Assistant helps humans to make this choice. To this end, it makes use of a methodology for ordering the mining algorithms that is based on the prev

O Objetivo desse trabalho é analisar, através de um estudo teórico e de uma pesquisa de campo, os possíveis atravessamentos da cultura contemporânea, com ênfase nas questões da eficiência e do consumo, na construção das primeiras relações mãe-bebê e suas repercussões nas práticas de maternagem. Buscou-se para isso apoio na Psicanálise, na História e na Sociologia. Diversos aspectos estão envolvidos nas expectativas atuais diante da maternidade relacionados com sentimentos de insegurança e incerteza presentes no mundo em que vivemos, onde a vida é marcada pela incerteza, instabilidade e fluidez dos valores. O sujeito contemporâneo por conta disso acredita precisar de especialistas para respaldá-lo nos mais diversos aspectos. As inseguranças presentes na situação da maternidade, em especial no caso do primeiro filho, são aqui colocadas em relevo, problematizando a busca de apoios disponibilizados por um mercado que hoje propõe respostas em forma de cursos, manuais e diversos outros produtos a serem consumidos.
This work aims to analyze, through a theoretical study and field research, the possible influences of contemporary culture, with an emphases on issues of efficiency and consumption, in the process of building the relationship between mother and baby and their repercussions of maternal practices. For that, a support on Psychoanalysis, History and Sociology was explored. A variety of aspects are involved in nowadays expectations on maternity. Feelings of insecurity and uncertainty are present in the contemporary world, where life is dictated by uncertainty, instability and fluidity of values. Due to that, contemporary subjects often believe they need specialists to back them up in many different areas. The insecurities present in maternity, especially when it comes to firstborns, are here highlighted, questioning the search of support made available by a market that today proposes answers in form of courses, textbooks and many other products to be consumed.

Learning violin is a challenging task requiring execution of pitch tasks with the left hand using a strong aural feedback loop for correctly adjusting pitch, concurrent with the right hand moving a bow precisely with correct pressure across strings. Real-time technological assistance can help a student gain feedback and understanding helpful for learning and maintaining motivation. This thesis presents real-time low-cost low-latency violin augmentations that can be used to assist learning the violin along with other real-time performance tasks. To capture bow performance, we demonstrate a new means of bow tracking by measuring bow hair de ection from the bow hair being pressed against the string. Using near- eld optical sensors placed along the bow we are able to estimate bow position and pressure through linear regression from training samples. For left hand pitch tracking, we introduce low cost means for tracking nger position and illustrate the combination of sensed results with audio processing to achieve high accuracy low-latency pitch tracking. We subsequently verify our new tracking methods' e ectiveness and usefulness demonstrating low-latency note onset detection and control of real-time performance visuals. To help tackle the challenge of intonation, we used our pitch estimation to develop low latency pitch correction. Using expert performers, we veri ed that fully correcting pitch is not only disconcerting but breaks a violinist's learned pitch feedback loop resulting in worse asplayed performance. However, partial pitch correction, though also linked to worse as-played performance, did not lead to a signi cantly negative experience con rming its potential for use to temporarily reduce barriers to success. Subsequently, in a study with beginners, we veri ed that when the pitch feedback loop is underdeveloped, automatic pitch correction did not signi cantly hinder performance, but o ered an enjoyable low-pitch error experience and that providing an automatic target guide pitch was helpful in correcting performed pitch error.

In this thesis we propose a digital archive model that permits users to access digitized documents easily, to study their content, to search them, as well as to enrich them by annotations or alternative classifications. The model contains a management system to store, visualize, organize, search and annotate these documents. Moreover, since the annotation process is laborious, reading a manuscript page takes sometimes hours, a solution is proposed to publish these documents online and to offer annotation tools to different user types to facilitate the annotation creation by a larger audience. The integrated assistant is developed by using case-based reasoning, it reasons from the registered traces of users’ interaction with the system, to suggest some help to the current userDans cette thèse nous proposons un modèle d’archive numérique, permettant aux utilisateurs d’accéder aux documents numériques facilement, d’étudier leur contenu, de les rechercher, ainsi que des les enrichir via des annotations et des classifications alternatives.

The purpose of this study was to examine a sample of students who participated in a student assistance program in Southwest Virginia. Using existing data from a school system in Southwest Virginia, this sample was observed to measure changes in student academic performance. The sample was also examined to determine the extent to which they instituted positive behaviors such as school attendance and reduction of disciplinary actions taken. In addition, this study assessed differences in demographic characteristics among student participants. Also studied was the extent to which gender differences related to academic performance and behavior.
Significant changes in students’ academic performance, attendance and disciplinary measures were established in the present study. Negative associations were established for those participating in the student assistance program and grade point average. Positive associations were found for those participating in SAP and attendance and disciplinary measures. No significant differences were yielded in the comparison of gender to academic performance and behavior.
SAP coordinators recorded that the majority of participants did improve since referral to program and most completed or currently remained in the student assistance program. However, a small percentage of students actually entered treatment programs following recommendations made to parents from the student assistance program committee.
This research assessed only the demographic and individual characteristics: gender, gifted or special education status, ethnicity and age. Therefore, other demographics such as socio economic status may offer additional explanation into academic and behavior outcomes of students involved in student assistance programs.Ph. D.

Recent advances in technology are changing the way how everyday activities are performed. Technologies in the traffic domain provide diverse instruments of gathering and analysing data for more fuel-efficient, safe, and convenient travelling for both drivers and passengers. In this article, we propose a reference architecture for a context-aware driving assistant system. Moreover, we exemplify this architecture with a real prototype of a driving assistance system called Driving coach. This prototype collects, fuses and analyses diverse information, like digital map, weather, traffic situation, as well as vehicle information to provide drivers in-depth information regarding their previous trip along with personalised hints to improve their fuel-efficient driving in the future. The Driving coach system monitors its own performance, as well as driver feedback to correct itself to serve the driver more appropriately.

This thesis project presents the web service choreography approach used for the composition of web services. It leverages the CHOReVOLUTION platform, a future-oriented and scalable platform, that is used to design and deploy web service choreographies. By using this platform, a use case that falls into the ITS domain is developed. This use case highlights the benefits of the web service choreography when used for the development of ITS applications. The necessary web services are designed and their interactions are defined through a choreography diagram that graphically represents how the services should collaborate together to fulfill a specific goal. By using the choreography diagram as input to the platform and by registering the web services on a web server, the choreography is deployed over the platform. The resulted choreography is tested in terms of services coordination. It is demonstrated that the platform can generate specific components that are interposed between the services and are able to take care of the services coordination for the use case created. Moreover, the execution time required to complete the choreography is measured, analyzed and reported under different conditions. Finally, it is shown that the execution time varies depending on the data that the services have to process and that the processing of huge data sets may lead to high execution times.Detta examensarbete behandlar hur man med hjälp koreografering av webbtjänster kan komponera webbtjänster. Det använder sig av CHOReVOLUTION plattformen, en framåtblickande och skalbar plattform, som används för att designa och verkställa koreografering av webbtjänster. Med denna plattform skapas ett användningsfall inom ITS-området. Detta fall belyser fördelarna med webbtjänskoreografi i samband med utveckling av ITS- applikationer. De nödvändiga webbtjänsterna designas och deras samspel definieras genom ett diagram för koreografin, som på ett grafiskt vis presenterar hur tjänsterna skall kollaborera för att nå ett specifikt mål. Genom att mata plattformen med data från diagrammet, och genom att registrera webbtjänster på en webbserver, verkställs koreografin. Med resultatet testas koordineringen av tjänsterna. I detta examensarbete visas det att plattformen kan skapa specifika komponenter som interagerar med tjänsterna, samt sköta koordineringen av tjänster som krävs för detta användningsfall. Exekveringstiden mäts, analyseras och rapporteras under flera olika omständigheter. Det demonstreras också att exekveringstiden varierar beroende på den data som tjänsterna måste behandla, och hur behandlingen av mycket stora datamängder kan leda till långa exekveringstider.
