Utvärdering utifrån ett mjukvaruutveckling perspektiv av ramverk för SharePoint / Evaluation from a software development perspective of a framework for SharePoint

Al-Battat, Ahmed, Anwer, Noora January 2017 (has links)
Inom ett företag eller en organisation finns det stor nytta av intranät som ett arbetsverktyg för att kunna dela information. Ett välfungerat intranät bidrar till ett bättre informationsflöde och ett effektivare samarbete. SharePoint är en plattform för intranät med interaktiva funktioner. Omnia är ett ramverk anpassad för Microsofts SharePoint 2013.I detta arbete undersöks hur Omnia fungerar som ett ramverk och vad produkten lämpar sig för. Omnia ramverket utvärderades noggrant och en oberoende bedömning utfördes under examensarbetet. Utvärderingen var baserad på vetenskapliga undersökningar som byggde på den kvalitativa och kvantitativa forskningsmetodiken. Utvärderingens huvudområden baserades på systemets prestanda, skalbarhet, arkitektur och funktionalitet. En testprototyp utvecklades under arbetets gång genom Omnia i from av en webbaserad applikation.Ramverket Omnia var lämplig för utveckling av interaktiva webbaserade applikationer för intranät i SharePoint. Dock saknade den färdig dokumentation/API, vilket gjorde utvecklingsprocessen mer avancerad. Lösningsarkitekturen för systemet uppfyllde kraven för skalbara system, eftersom den baserades på lagerarkitektur. Systemet hade även bra prestanda, dock försämrades den efter att antalet användare översteg ettusen. Funktionaliteten testades med hjälp av två olika tester, vilket visade att produkten är lämplig för att användas i intranät. / The functionality was tested by two different tests, which showed that the product is suitable for usage in the intranet within a company or an organization, there are great benefits from using intranet as a tool for sharing of information. A good intranet contributes to a better flow of information and effective cooperation. SharePoint is a platform for intranet with interactive features, it makes the job easier for staff and even the company. The framework Omnia is a solution designed for Microsoft SharePoint 2013.This essay evaluates how Omnia acts as a framework and what the product is suitable for. Omnia framework evaluates carefully and is an independent assessment carried during this essay. The evaluation is based on scientific studies which are based on the qualitative and quantitative research methodology. The evaluator's main areas are based on system performance, scalability, architecture and functionality. A test prototype develops during the process in the form of an employee vacation request application by the development framework Omnia.The framework Omnia is considered to be suitable for the development of interactive web-based applications for SharePoint. The architecture for the system meets the requirements for scalable systems because it is based on the tier architecture. The system also has good performance but it needs to be improved if the number of users exceeds one thousand. The functionality of this product is quite suitable for the system's usage.

THE ROLE OF BACTERIAL ROOT ENDOPHYTES IN TOMATO GROWTH AND DEVELOPMENT

Tri Tien Tran (14212937) 17 May 2024 (has links)
<p>  </p> <p>Plant roots form an intimate relationship with a diversity of soil microorganisms. Some soil-borne microbes cause harmful diseases on crops, but others promote plant growth and enhance host resilience against stressors. Beneficial bacteria have a high potential as a strategy for sustainable agricultural management, many of which have been recognized and commercialized for improving crop growth. Unfortunately, field inoculants of beneficial bacteria often give inconsistent results due to various environmental factors hindering their beneficial properties. Improving crop production utilizing beneficial bacteria requires two approaches: 1) breeding for crops with the enhanced association for beneficial bacteria and 2) improving formulation methods for producing more potent microbial products. To contribute to these goals, we address three critical questions utilizing the tomato root microbiome as a model system. First, we asked how beneficial root-associated bacteria could be efficiently identified. We developed a strategy to select beneficial bacteria from a novel collection of 183 bacterial endophytes isolated from roots of two field-grown tomato species. The results suggest that isolates with similar traits impact plant growth at the same levels, regardless of their taxonomic classification or host origin. Next, we asked whether host genetics contribute to the root microbiome assembly and response to beneficial microbes. An assessment of the root microbiome profile and plant binary interaction experiments suggested the role of host genetics in influencing root recruitment and response to beneficial bacteria. Subsequently, we asked whether root-associated bacteria induce physiological changes in root tissues in the host. We identified two isolates from our bacterial endophyte collection that significantly promoted the growth of tomato genotype H7996 (<em>Solanum lycopersicum</em>). Plant-binary interaction experiments suggested a significant increase of cell wall lignification in the root vasculature starting 96-hour post-inoculation with beneficial bacteria. Additional studies are needed to uncover a possible correlation between the induced vasculature lignification and the growth-promoting effects of the two isolates on H7996. Altogether, our findings highlight the multi-faceted role of root-associated bacteria in promoting plant growth and support the development of crop improvement strategies in optimizing host association with soil bacteria.</p>

虛擬角色的智慧財產權保護 ──以著作權法與商標法為核心 / The Intellectual Property Protection of Fictional Characters: Interplay of Copyright and Trademark Law

戴士捷, Tai, Shih Chieh Unknown Date (has links)
本論文欲研究虛擬角色於既有智慧財產權法制下的保護途徑,並以商標法與著作權法為核心,探討與虛擬角色保護相關之智慧財產權議題;以及著作權與商標法併用於保護虛擬角色的趨勢之下,對公共領域可能造成的影響,並由此進一步討論利用人地位之保護。 漫畫、卡通等文化創意產業的繁榮,進一步帶動了消費者對於角色相關商品的喜愛與需求,近來隨著網路、智慧型手機的發展,不僅提升了角色人物的普及率,也使得角色的呈現方式更加多元,角色經濟所帶來經濟效益與日俱增,且儼然成為文創產業未來的產品競爭力來源。然而,諸如角色造型與其背景故事,這些藝術創作的心血結晶應如何透過既有智慧財產權法律體系加以保護? 又創作人在尋求智慧財產權保護的過程中會遭遇何等障礙?目前我國學界尚未有深入之研究探討,故為本論文所欲研究之重點。 本論文將以虛擬角色著作權保障之議題為始,從比較法角度探討虛擬角色著作權保護之不同判斷標準,以及各判斷標準下所衍生之問題;再探討虛擬角色取得商標權保護之可能性,以及權利人在取得商標保護過程中所可能面臨之阻礙,並進一步論述虛擬角色商標權保護範圍之問題。 此外,在探討如何以智慧財產權法保護角色之餘,如何平衡保護利用人的權益,更是智慧財產權法一個恆久而困難的問題。由於虛擬角色對其他創作人而言,亦是一個具有發展性的創作素材;如果過度保護虛擬角色,則可能對其他利用人的創作構成阻礙,造成創作火花熄滅的負面效應 。因此,本論文亦將虛擬角色保護的主題與思想表達合併原則的運用、保護商標戲謔仿作等議題相互結合,探討擴大角色智慧財產權保護的趨勢下,如何對利用人地位給予應有的保護。 最後,則冀望透過本論文所提出的歸納結果與淺見,能夠提供相關文創產業工作者參考,進而使國內文創產業重視虛擬角色相關智慧財產權的策略佈局,從而引領我國文化創意產業拓展商機。

Informatics for devices within telehealth systems for monitoring chronic diseases

Adeogun, Oluseun January 2011 (has links)
Preliminary investigation at the beginning of this research showed that informatics on point-of-care (POC) devices was limited to basic data generation and processing. This thesis is based on publications of several studies during the course of the research. The aim of the research is to model and analyse information generation and exchange in telehealth systems and to identify and analyse the capabilities of these systems in managing chronic diseases which utilise point-of-care devices. The objectives to meet the aim are as follows: (i) to review the state-of-the-art in informatics and decision support on point-of-care devices. (ii) to assess the current level of servitization of POC devices used within the home environment. (iii) to identify current models of information generation and exchange for POC devices using a telehealth perspective. (iv) to identify the capabilities of telehealth systems. (v) to evaluate key components of telehealth systems (i.e. POC devices and intermediate devices). (vi) to analyse the capabilities of telehealth systems as enablers to a healthcare policy. The literature review showed that data transfer from devices is an important part of generating information. The implication of this is that future designs of devices should have efficient ways of transferring data to minimise the errors that may be introduced through manual data entry/transfer. The full impact of a servitized model for point-of-care devices is possible within a telehealth system, since capabilities of interpreting data for the patient will be offered as a service (c.f. NHS Direct). This research helped to deduce components of telehealth systems which are important in supporting informatics and decision making for actors of the system. These included actors and devices. Telehealth systems also help facilitate the exchange of data to help decision making to be faster for all actors concerned. This research has shown that a large number of capability categories existed for the patients and health professionals. There were no capabilities related to the caregiver that had a direct impact on the patient and health professional. This was not surprising since the numbers of caregivers in current telehealth systems was low. Two types of intermediate devices were identified in telehealth systems: generic and proprietary. Patients and caregivers used both types, while health professionals only used generic devices. However, there was a higher incidence of proprietary devices used by patients. Proprietary devices possess features to support patients better thus promoting their independence in managing their chronic condition. This research developed a six-step methodology for working from government objectives to appropriate telehealth capability categories. This helped to determine objectives for which a telehealth system is suitable.

L’ocularisation vidéoludique : une typologie des points de vue à l’intérieur des phases interactives dans les jeux vidéo tridimensionnels

Chabot, Philippe 08 1900 (has links)
Mémoire en jeu vidéo / Un survol des théories sur le point de vue et sur l’ocularisation au cinéma permet de constater que les recherches ont été bien menées dans ce champ d’étude. Or, le même bilan ne peut pas être fait en jeu vidéo. Le point de vue vidéoludique n’a pas été analysé et théorisé avec la même exhaustivité et le même approfondissement. Beaucoup de lacunes sont encore visibles et le but de ce mémoire est justement d’en cibler quelques-unes et de les combler. Cette recherche se penche ainsi sur les points de vue en jeu vidéo et plus précisément, sur ceux que l’on retrouve à l’intérieur des phases interactives (les cinématiques sont par exemple exclues) dans les oeuvres tridimensionnelles. Une typologie de l’ocularisation vidéoludique, c’est-à-dire une nouvelle catégorisation des différents types de visualisation, est présentée, décortiquée et exemplifiée tout au long de ce mémoire. Celle-ci est plus approfondie que celles déjà développées par le passé, car elle prend en compte une plus grande variété de caractéristiques : l’ancrage, le positionnement, la mobilité et le contrôle offert au joueur. Aussi, elle détaille l’impact des différents points de vue sur l’expérience de l’utilisateur en privilégiant deux axes : l’esthétique et la fonctionnalité. À terme, ce mémoire permet d’instaurer une théorie de l’ocularisation plus aboutie dans les études vidéoludiques. / An overview of the theories on the point of view and on the ocularization in cinema shows that the researches were well conducted in this field of study. However, the same report cannot be done in video game. The notion of point of view has not been analyzed and theorized with the same exhaustiveness and deepening. Many gaps are still visible and the purpose of this thesis is to target some of them and to fill them. This research thus examines the points of view in video games and more specifically, those that are found within the interactive phases (cutscenes are for example excluded) in three-dimensional games. A typology of ocularization, that is to say a new categorization of the different types of visualization, is presented, analyzed and exemplified throughout this thesis. This one goes into deeper details than those already developed in the past, because it takes into account a greater variety of characteristics: anchor, positioning, mobility and control available to the player. Also, it details the impact of the various points of view on the user’s experience by focusing on two axes: aesthetic and functionality. Ultimately, this thesis allows establishing a more elaborate theory on ocularization in video game studies.

"Se sentir vivant" : le regard d’aînés et d’auxiliaires familiaux et sociaux sur le soutien à domicile en contexte d’inégalités sociales

Fournier, Aude 01 1900 (has links)
Cette recherche s’intéresse au soutien à domicile des personnes âgées dites « en perte d’autonomie » dans un contexte où, d’une part, les inégalités socioéconomiques parmi ce groupe sont marquées et, d’autre part, les services à domicile tendent vers une standardisation et une marchandisation. L’autonomie a été mobilisée comme concept pour mieux appréhender les conditions de vie et les rapports sociaux qui nuisent ou contribuent au bien-être des aînés à domicile, de leur propre point de vue et de celui des auxiliaires familiaux et sociaux qui interviennent auprès d’eux. Ce groupe d’acteurs est généralement évoqué dans la littérature comme ayant une vision sociale et globale des personnes qu’ils visitent, de par leur proximité et intrusion dans l’espace de vie de ces dernières. Le discours dominant par rapport au bien-être des personnes âgées (bien-vieillir ou, en anglais, successful aging) dans la littérature en gérontologie ou dans les documents institutionnels s’articule autour d’une conception fonctionnelle de l’autonomie, au détriment des dimensions plus sociales et relationnelles. Cette recherche a ainsi cherché à investir une perspective sociorelationnelle de l’autonomie, qui se retrouve en sciences sociales chez des auteurs tels que Druhle, Sen, McAll, Honneth, Guillemard et Castoriadis. Ce cadre conceptuel au cœur duquel se trouvent notamment les notions de reconnaissance et de rapports sociaux inégalitaires a servi de porte d’entrée pour analyser 10 entrevues semi-dirigées avec des auxiliaires familiaux et sociaux (qui ont évoqué, chacun, la situation des trois dernières personnes visitées, pour un total de 30 exemples de cas) et 14 entrevues semi-dirigées avec des personnes âgées recevant des services à domicile. Au croisement de ces regards, les résultats de cette recherche suggèrent que les conditions de vie matérielles et relationnelles ont un impact déterminant sur la possibilité pour les aînés de « se sentir vivants » et que pour les personnes les plus défavorisées et/ou isolées, le soutien à domicile se traduit le plus souvent en une situation de « confinement », de « maintien » à domicile. Par rapport à la relation avec les auxiliaires, il apparaît que l’amélioration du bien-être des aînés recevant de l’aide à domicile passe, entre autres, par la création d’un espace relationnel autonome dans lequel la personne existe non seulement comme « corps », mais également comme « esprit ». Par-delà des services offerts, c’est ce type d’interaction (attentif et respectueux des habitudes, intentions et projets qui ont rempli la vie des personnes aidées) qui retient le plus leur attention et mobilise l’essentiel de leur discours sur le soutien à domicile. Il semble également que ce soit parfois en se faisant marginal dans la vie des gens et en créant simplement des espaces favorables à une autonomie collective que le réseau de services peut avoir les impacts les plus positifs sur les personnes, de leur propre point de vue. / This study aims to explore the elder’s home support, more narrowly the experience of people characterized as « in loss of autonomy » in a context where, on one hand, socioeconomic inequalities in this group are important, and, on the other hand, home support services tend toward a standardization and a commoditization. The concept of autonomy has been used to better apprehend the living conditions and the social relations that positively or negatively affect the wellbeing of elders at home, from their own perspective or from those of the visiting caregivers who work with them. The latter are generally mentioned in the literature has having a social and global perspective on the people they visit, as they are closely tied to them and intrude in their own living space. In the gerontology literature and in institutional documents, the dominant discourse related to wellbeing of the elderly (« successful aging » or, in French, « bien-vieillir ») is articulated around a functional conception of autonomy, depriving it of its more social and relational dimensions. This research has developed a social perspective on autonomy grounded in social sciences and based on authors such as Druhle, Sen, McAll, Honneth, Guillemard and Castoriadis. This conceptual framework relies on notions of recognition and social inequality and was used in analyzing our 10 semistructured interviews with caregivers and 14 more with elders receiving homecare. Each of the 10 caregivers were asked to relate their last three visits, adding up to a total of 30 case studies. At the crossroads of these narratives, the results of this research suggest that material and relational living conditions do have a decisive impact on elders’ possibility to « feel alive ». For those most disadvantaged and/or isolated, home support most often translates in situations of containment, of retention at home. With regards to relationships with caregivers, it appears that improvement of elders’ wellbeing receiving home support is related, among other things, to the creation of autonomous relational space where the person exists not only as a « body » with needs, but also as a « spirit ». Beyond the provided services, it is the kind of interaction (careful, mindful, respectful of habits, intentions and projects that fulfill the life of the assisted individuals), that occupies most of their narrative on home care services. According to the elders, from time to time, it seems that the health care system can have more significant positive impact by creating spaces propitious to collective autonomy and with marginal intervention.

Three Factor Authentication Using Java Ring and Biometrics

Chitiprolu, Jyothi 17 December 2004 (has links)
Computer security is a growing field in the IT industry. One of the important aspects of the computer security is authentication. Using passwords (something you know) is one of the most common ways of authentications. But passwords have proven to provide weak level of security as they can be easily compromised. Some other ways of authenticating a user are using physical tokens, (something you possess) and biometrics, (something you are). Using any one of these techniques to secure a system always has its own set of threats. One way to make sure a system is secure is to use multiple factors to authenticate. One of the ways to use multiple factors is to use all the three factors of authentication, something you possess, something you are and something you know. This thesis discusses about different ways of authentication and implements a system using three factor authentication. It takes many security aspects of the system into consideration while implementing it, to make it secure.

Apprentissage ouvert de representations et de fonctionnalites en robotique : anayse, modeles et implementation

PAQUIER, Williams 19 March 2004 (has links) (PDF)
L'acquisition autonome de representations et de fonctionnalites en robotique pose de nombreux problemes theoriques. Aujourd'hui, les systemes robotiques autonomes sont concus autour d'un ensemble de fonctionnalites. Leurs representations du monde sont issues de l'analyse d'un probleme et d'une modelisation prealablement donnees par les concepteurs. Cette approche limite les capacites d'apprentissage. Nous proposons dans cette these un systeme ouvert de representations et de fonctionnalites. Ce systeme apprend en experimentant son environnement et est guide par l'augmentation d'une fonction de valeur. L'objectif du systeme consiste a agir sur son environnement pour reactiver les representations dont il avait appris une connotation positive. Une analyse de la capacite a generaliser la production d'actions appropriees pour ces reactivations conduit a definir un ensemble de proprietes necessaires pour un tel systeme. Le systeme de representation est constitue d'un reseau d'unites de traitement semblables et utilise un codage par position. Le sens de l'etat d'une unite depend de sa position dans le reseau. Ce systeme de representation possede des similitudes avec le principe de numeration par position. Une representation correspond a l'activation d'un ensemble d'unites. Ce systeme a ete implemente dans une suite logicielle appelee NeuSter qui permet de simuler des reseaux de plusieurs millions d'unites et milliard de connexions sur des grappes heterogenes de machines POSIX. Les premiers resultats permettent de valider les contraintes deduites de l'analyse. Un tel systeme permet d'apprendre dans un meme reseau, de facon hierarchique et non supervisee, des detecteurs de bords et de traits, de coins, de terminaisons de traits, de visages, de directions de mouvement, de rotations, d'expansions, et de phonemes. NeuSter apprend en ligne en utilisant uniquement les donnees de ses capteurs. Il a ete teste sur des robots mobiles pour l'apprentissage et le suivi d'objets.

Impact of Cascading Failures on Performance Assessment of Civil Infrastructure Systems

Adachi, Takao 05 March 2007 (has links)
Water distribution systems, electrical power transmission systems, and other civil infrastructure systems are essential to the smooth and stable operation of regional economies. Since the functions of such infrastructure systems often are inter-dependent, the systems sometimes suffer unforeseen functional disruptions. For example, the widespread power outage due to the malfunction of an electric power substation, which occurred in the northeastern United States and parts of Canada in August 2003, interrupted the supply of water to several communities, leading to inconvenience and economic losses. The sequence of such failures leading to widespread outages is referred to as a cascading failure. Assessing the vulnerability of communities to natural and man-made hazards should take the possibility of such failures into account. In seismic risk assessment, the risk to a facility or a building is generally specified by one of two basic approaches: through a probabilistic seismic hazard analysis (PSHA) and a stipulated scenario earthquake (SE). A PSHA has been widely accepted as a basis for design and evaluation of individual buildings, bridges and other facilities. However, the vulnerability assessment of distributed infrastructure facilities requires a model of spatial intensity of earthquake ground motion. Since the ground motions from a PSHA represent an aggregation of earthquakes, they cannot model the spatial variation in intensity. On the other hand, when a SE-based analysis is used, the spatial correlation of seismic intensities must be properly evaluated. This study presents a new methodology for evaluating the functionality of an infrastructure system situated in a region of moderate seismicity considering functional interactions among the systems in the network, cascading failure, and spatial correlation of ground motion. The functional interactions among facilities in the systems are modeled by fault trees, and the impact of cascading failures on serviceability of a networked system is computed by a procedure from the field of operations research known as a shortest path algorithm. The upper and lower bound solutions to spatial correlation of seismic intensities over a region are obtained.
