L'objectif de cette thèse est de démontrer que l'Emission Acoustique (AE) est une technique appropriée pour devenir un outil de diagnostic de l'état de charge, de santé et de sécurité pour les batteries lithium-ion. Ces questions sont actuellement des points clés important pour l'amélioration des performances et des durées de vie de la technologie. La structure de ce document est organisée en deux principaux chapitres expérimetaux l'un consacré à deséléments lithium-ion composés de composés d'intercalation et l'autre à desalliages de lithium.Dans le premier cas, les résultats présentés concernent le suivi par AE de la formation de la SEI et de la première intercalation des ions lithium dans la structure du graphite pour des éléments LiFePO4/C. Les événements AE provenant de plusieurs sources ont été identifiés et correspondent à la formation de gaz (bulles) et à des phénomènes de craquelures (ouvertures du bord des plans de graphène quand la SEI est formée et l'écartement quand les stades d'insertion du graphite-lithium sont finis). De plus, une étude par spectroscopie d'impédance a été menée durant un vieillissement calendaire en température sur des éléments formés à différents régimes de courant. Dans le second cas, le mécanisme d'insertion/extraction du lithium dans des éléments LiAl/LiMnO2 a été étudié en associant plusieurs techniques incluant des techniques électrochimiques, AE et post-mortem pour évaluer les mécanismes de dégradation. Lors du cyclage, les événements acoustiques sont plus intenses lors du processus de décharge et ils peuvent être attribués principalement à l'alliage avec la transformation de phase de -LiAl en -LiAl accompagnée d'une expansion volumique importante. L'émission acoustique peut ainsi offrir une nouvelle approche pour gérer le fonctionnement des technologies lithium-ion basées non plus seulement sur des paramètres électrochimiques classiques mais aussi sur des paramètres acoustiques. Des nouveaux d'états de santé et de sécurité peuvent ainsi être envisagés. / The aim of this thesis is to demonstrate that the Acoustic Emission (AE) is an appropriate technique for diagnostics of for state of charge, state of health and state of safety for lithium-ion batteries. The availability and optimization of the latter issues are key points for both performance and durability improvements of this technology. The frame of this document is organized in two main result chapters focused on AE study of two different Li-ion technologies. The beginning of the thesis is focused on the monitoring of the SEI formation by AE and the first lithium ion intercalation inside the graphite structure for LiFePO4/C cells. AE events coming from different sources have been analyzed and identified. It was found that they correspond to gas emission (bubbles) and cracking phenomena (opening on the edge of the graphene plane when the SEI is formed and spacing when lithium graphite insertion stages are completed). Further, a study of the calendar aging process supported by electrochemical impedance spectroscopy linked the aging rate with the mechanism of the SEI formation characterized by AE monitoring. The second part of the thesis studied of lithium ion insertion/extraction in LiAl/LiMnO2 cells combining a variety of techniques including electrochemical characterization, AE monitoring and post-mortem analysis in order to evaluate the degradation mechanisms. It was found that during the cycling, the acoustic events are much more intensive during the discharge process and they can be attributed mainly to the alloy were the phase transformation from -LiAl to -LiAl and a huge volume expansion occurs. It was found that battery operation under abusive conditions (overcharge, overdischarge) can be detected by AE providing new rates for battery safety management.

The aim of this project has been to explore alternative technical solutions for making own extensions in the CMS SiteVision. The purpose of these extensions is to retrieve data from an external API (Office 365) which requires OAuth 2.0 authentication. Additional, the alternative technical solutions have been evaluated and compared. The comparisons have been made based on criteria developed through interviews with professional IT-consultants. The purpose of the project has been to contribute to more efficient digitization, integration and individualization of datasystems. Within the project, an applied example (POC) has been created to show examples of how the technology can be used. In this example, Java Portlets have been used to implement the above functionality. WebApps in SiteVision have also been studied since this technology is an alternative to Java Portlets. The survey shows that it is fully possible to create a separate extension in SiteVision that performs authentication with OAuth 2.0 and then uses it to retrieve data from an external API. The results from the comparison between the two different Java Portlets and WebApps technologies show that there are pros and cons of each technique. The alternatives studied where comparable in performance. Individual circumstances can dictate which alternative is best. / Det övergripande syftet med detta projekt har varit att bidra till en effektiviserad digitalisering och individualisering. Målet för projektet har varit att undersöka alternativa tekniska lösningar för att göra egna tillägg i CMS:et SiteVision. Tillägg vars uppgift består i att hämta data från ett externt API (Office 365) som kräver autentisering med OAuth 2.0. Vidare har de alternativa tekniska lösningarna värderats och jämförts. Jämförelsen har gjorts utifrån kriterier som tagits fram genom intervjuer med utvecklare på ett IT-konsultbolag. Inom projektet har ett tillämpat exempel (POC) skapats för att visa exempel på hur tekniken kan användas. I detta exempel har Java Portlets använts för att implementera ovanstående funktionalitet. Även WebApps i SiteVision har studerats då den tekniken utgör ett alternativ till Java Portlets. Undersökningen visar att det är fullt möjligt att skapa ett eget tillägg i SiteVision som genomför autentisering med OAuth 2.0 och sedan använda denna för att hämta data från ett externt API. Resultaten från jämförelsen mellan de två olika teknikerna Java Portlets och WebApps visar att det finns för- och nackdelar med respektive teknik. Båda alternativen framstår som jämstarka i jämförelsen. De individuella omständigheterna kring ett framtida användande bör fälla avgörandet för vilken teknik som väljs.

Bakgrund: PDMS, Patient Data Management System, är ett kliniskt informationssystem som är speciellt utvecklat för intensivvård som genererar stora mängder patientdata. Systemet samlar automatiskt in patientdata från övervakning och medicinskteknisk apparatur och presenterar informationen på ett överskådligt sätt. Tidigare forskning belyser framförallt användbarheten, den minskade dokumentationstiden samt fördelar med läkemedelshanteringen men visar motsägelsefulla resultat vad gäller vad den frigjorda tiden används till. Syfte: att belysa intensivvårdssjuksköterskors erfarenhet av att använda PDMS i vårdarbetet. Metod: kvalitativ intervjustudie med intensivvårdssjuksköterskor som analyserats med hjälp av en kvalitativ innehållsanalys. Resultat: i resultatet framträder fem kategorier; patientnära vårdande, evidensbaserad vård, olika former av kvalitetsutveckling, säker vård och informatik. Dessa kategorier återger intensivvårdssjuksköterskornas erfarenheter av att arbeta med PDMS och resultatet visar tydligt att PDMS ökar patientsäkerheten på flera sätt. Konklusion: Ökad vårdkvalitet, minskad dokumentationstid, mer lättförståeligt kontinuerligt lärande för personalen, möjlighet till uppföljning och forskning samt säkrare läkemedelshantering anses vara de största vinsterna med PDMS. Sammantaget bidrar samtliga faktorer till en ökad patientsäkerhet. / Background: PDMS, Patient Data Management System, is a clinical information system specially developed for intensive care which generates a large amount of patient data. The system automatically collects patient data from monitoring and medical equipment and presents the information in a clear overall view. Previous research highlights especially usability of the system, reduced time spent on documentation and benefits with handling medications but shows contradictory results in terms of what the released time is used for. Aim: to highlight intensive care nurses experiences of using PDMS in nursing. Method: qualitative interview-study with intensive care nurses which was analyzed with qualitative content analysis. Results: five categories came forward in the result; close-to-patient care, evidece-based care, different forms of quality developement, safe care and informatics. These categories reflects the experiences of working with PDMS among intensive care nurses and the results clearly demonstrate that PDMS increases patient safety for several reasons. Conclusion: increased quality of care, reduced documentation time, more easy-to-understand continuous learning for the staff, opportunity to follow-up and posibility for reasearch and safer handling with medications are considered the biggest gains with PDMS. Overall, all factors contribute to increased patient safety.

[pt] Atualmente, a Tecnologia da Informação (TI) tem assumido papel essencial para o alcance da administração eficiente, tanto no nível estratégico como no operacional, oferecendo benefícios para os negócios que incluem redução de custo, aumento da produtividade, qualidade, flexibilidade e inovação. E um dos recursos empregados é a implantação de um Sistema de Gestão de Armazéns, denominado Warehouse Management System (WMS), software que recebe as informações pertinentes ao armazém, gerando respostas para uma melhor movimentação, armazenagem, separação e expedição dos produtos, conforme as necessidades da organização. No entanto, a implantação de um sistema WMS pode ser considerada bem mais do que um projeto de tecnologia, que envolve mudanças estruturais e comportamentais, tornando-se um processo de risco relativamente alto e complexo. Este trabalho tem como objetivo identificar e planejar respostas aos riscos na implantação de um WMS no novo armazém de uma grande empresa brasileira do setor de cosméticos. Os resultados obtidos comprovaram inúmeras atividades que devem ser gerenciadas em favor do não comprometimento dos objetivos propostos da empresa, embora sabendo que o risco é algo incerto quanto à sua ocorrência. Ainda assim, para os futuros usuários do WMS, compreender a inclusão do gerenciamento de riscos nos seus projetos de implantação irá trazer maior probabilidade de sucesso, pois quanto mais forem conhecidos os riscos e as ações de mitigação, mais confiança e segurança as empresas terão em projetos desta natureza. / [en] Currently, Information Technology (IT) has assumed crucial role for achieving the efficient administration at both the strategic and the operational, providing business benefits that include reducing costs, increasing productivity, quality, flexibility and innovation. And one of the resources used is the implementation of a Warehouse Management System, called Warehouse Management System (WMS) software that receives the relevant information to the warehouse, generating responses for improved handling, storage, picking and shipping of products as the organization s needs. However, the implementation of a WMS system can be considered much more than a technology project that involves structural and behavioral changes, becoming a process of relatively high risk and complex. This study aims to identify and plan responses to the risks of implementing a new WMS in the warehouse of a large company in the cosmetics industry. The results confirmed many activities that must be managed in favor of non-commitment of the proposed objectives of the company, while knowing that the risk is somewhat uncertain as to its occurrence. Still, for future users of the WMS, to understand the inclusion of risk management in their deployment projects will bring greater likelihood of success, because as more becomes known risks and mitigating actions, more confidence and security firms will take into projects of this nature.

I dagens konkurrensutsatta marknad är det en nödvändighet för organisationer att kontinuerligt effektivisera sina affärsprocesser med avgörande betydelse för tillväxt. Eftersom dessa processer är essentiella byggstenar för en organisations framgång har systemstöd avseende processmanagement blivit en viktig faktor i strävan efter att uppfylla organisationens mål och förbättra sin konkurrenskraft. Med detta i åtanke är det intressant att studera i vilken grad workflowsystem kan bidra till att förbättra organisationers affärsprocesser. Mot bakgrund av dessa snabbskiftande marknadsförutsättningar kommer studien behandla processrelaterade systemstöd med syftet att undersöka situationen för samtidens workflowbaserade optimeringar och utröna framtida visioner gällande automatisk processmanagement. Undersökningen har utförts genom en kvalitativ kund- och marknadsanalys avseende IT-företaget Medius AB där intervjuer, deltagande observationer och dokumentstudier legat till grund för en abduktiv analys. Företaget är en leverantör av processrelaterat IT-stöd och den övergripande affärsidén är att med hjälp av system förenkla och automatisera organisationers skilda processer. Studien visar bland annat att leverantörserbjudanden och definitioner gällande processmanagement skiljer sig åt globalt och nationellt och att det i dagens konkurrensutsatta marknad är svårt att motivera processer utöver sådana som genererar en direkt organisationsnytta. Vidare framkommer trender inom processmanagementområdet, bland annat Case Management, Business Process Management och outsourcing av organisationsprocesser. Studien visar också att den framtida workflowmarknaden förutspås innehålla produkter som stödjer hela organisationer involverandes partner, leverantörer och kunder och inte endast interna processer. / In today's competitive market it is a necessity for organizations to continuously improve their business processes which are critical to growth. Since these processes are essential for organizational success it has become important to support them via information systems in order to meet organizational goals and to improve competitiveness. Thus it is interesting to study to what extent workflow systems can help improve organizations' business processes. In light of these rapidly changing market conditions, this study will examine process-related system support with the aim to investigate the situation of today's workflow-based optimizations, and explore future visions regarding automatic process management. The study was conducted through a qualitative customer and market analysis for the IT company Medius AB, where interviews, participant observations and document studies formed the basis of an abductive analysis. The company is a supplier of process-related IT support and its overall business concept is to offer systems to simplify and automate organizations' separate processes. The result of this study shows, for example, that the definitions and offerings from the vendors differ globally and nationally, and that it is difficult in today's competitive market to justify processes other than those that generate direct organizational benefits. Furthermore, different trends in the field of business process management have been identified, a few examples being Case Management, Business Process Management and outsourcing of organizational processes. The study also shows that the future workflow market is predicted to contain products that support the entire organization and not only specific processes, including partners, suppliers and customers.

Idag har de flesta företag och organisationer någon form för intranät-lösning. Dessa lösningar kan vara både mer och mindre sofistikerade, men har oftast det samma syfte; att distribuera organisationens information till dess medlemmar. Denna uppsats ägnar sig åt intranät och fördjupar sig i ett begrepp som vuxit starkt de senaste åren, nämligen Content Management System (CMS). Jag fokuserar särskilt på val av Open Source CMS, för implementation i mindre organisationers intranät. Uppsatsen är ett resultat av omfattande litteraturstudier inom sitt område och bygger främst på vetenskapliga artiklar av ledande experter. Ytterligare en källa är resultatet av en enkätundersökning, som också redovisas i uppsatsen. Denna enkät hade som ändamål, att kartlägga användares attityder till deras CMS-intranät. Uppsatsens kanske viktigaste resultat är en redogörelse för hur ett moduliserad CMS-intranät skulle kunna utformas, baserad på bl.a. Knowledge Management-teori, där tyngdpunkten ligger på de personliga referensernas betydelse för en människas tolkning av sin omgivning, och logisk kategorisering av information. / Today, most companies and organizations have some kind of intranet solution. These system solutions vary and tend to be either more or less sophisticated, but the overall purpose remains the same; distributing the organizations information to its members. This essay is about intranet-development, and mainly devoted to explore a concept which has grown rapidly in recent years; Content Management System (CMS). I’m particular focusing on how to choose a suitable Open Source CMS, for implementation in a small organizations intranet. The essay is the result of vast literature studies, mainly based on scientific articles from leading experts within their field. In addition I have also carried out a survey in a company intranet, in order to investigate the users’ attitude towards their CMS-intranet. One of the most important results of the essay is my model of a modularized CMS-intranet, partially based on Knowledge Management-theory and the importance of appropriate references in order to interpret our surroundings, and logical categorization of information.

I denna uppsats kommer vi dokumentera vidareutvecklingen av Softwerk AB’s Content Management System kallat AppCMS. I dagsläget innefattar AppCMS plattformarna iOS, Android och Windows Phone. Kunderna till Softwerk AB har dock uttryckt ett behov av att även kunna nå ut till sina användare med en webbaserad samt en utskrivningsbar lösning. AppCMS’s exportformat har därför analyserats för att undersöka möjligheten till att återanvända det existerande exportformatet från AppCMS  även för dessa plattformarna. Undersökningen gav klartecken för att påbörja implementationen av de olika lösningarna. Resultatet av arbetet blev ett tillskott till AppCMS i form av en webb- samt en utskrivningsbar version. I uppsatsen beskrivs de problem vi stött på, hur vi hanterat dessa samt vilka beslut som har tagits. / In this essay we will follow the continuous development of the company Softwerk´s Content Management System (CMS) called AppCMS. AppCMS currently includes the following platforms, iOS, Android and Windows Phone. The customers of Softwerk have expressed the need of also being able to reach their customers with a web based as well as a pdf version. AppCMS’s export format have therefore been analyzed to evaluate the possibility of reusing the existing format from AppCMS for these platforms as well. The examination confirmed that the existing format could be reused for the new solutions and that the implementation phase could begin. This work resulted in an addition to AppCMS in the shape of a web and pdf based version. The essay describes the problem we encountered, how we handled them as well as the decisions taken in the process.

eLearning is rapidly spreading into the high school learning environment. This research attempts to find desirable and workable features of an eLearning resource that would sustain high school learning communities. The basis of the instrumental case study was the Cambridge International Examination course offered by an eLearning institution over a period of two and a half years. Data was gathered by means of various questionnaires, focus groups, interviews and quantitative analysis of computer log files of activity. Content analysis was performed by comparing research data with information (such as various eLearning models) obtained from the literature review. Similarities and differences were found in the way eLearning is used by high school learners and teachers versus university students and lecturers. Desirable and workable features were identified and the reasons for these explored. A number of suggestions are made that would contribute to sustaining eLearning for high school learners. / Thesis (DPhil)--University of Pretoria, 2008. / Information Science / unrestricted

No. of bitstreams: 1 Cristiano Silveira Ribeiro.pdf: 2448117 bytes, checksum: 889c675170a8e8da34bd17c348d39bf5 (MD5) Previous issue date: 2016-02-26 / This study aims to investigate the relationship among environmental training in the companies and the performance of the Environmental Management System. It has been investigated whether the Environmental Training based upon planning, implementation and evaluation can be related with the Environmental Performance. Based on the theoretical framework, an analytical model has been developed, in which the relationships among the constructs can be studied. To achieve the objectives of this study, a questionnaire was developed and scales were used to measure the constructs involved in the analysis. the structural equation modeling has been used as the core analysis method. The sample consisted of 105 respondents which perform professionally in ISO 14001 certified companies or in companies that are not certified but that have a minimum structure of an environmental management system. The results of the analysis showed a strong relationship among the environmental training planning, environmental training implementation, environmental training assessment and environmental performance, explaining that the theoretical references pointed at the time of construction of the analysis model. It was found a positive relationship of the Planning with Execution, and the Execution with Performance, and this last relation was enhanced by the mediating action of the Environmental Training Evaluation. It was concluded that the theoretical framework in related disciplines the Environmental Training to study the stages of planning, implementation and evaluation, as in the study of environmental performance, provide resources for the establishment of a model which is able to explain the relationship between environmental training and environmental performance. This study, in addition to contributing to the theories related to the environmental training and environmental performance, shows to companies, environmental managers and human resource professionals, the importance of systemic environmental training programs, starting from planning, according to the implementation and evaluation and confirms that it is a strategic role within the organization, and reinforces the importance of training assessment due to its mediating role in enhancing results in environmental performance coming from environmental training. / O presente trabalho se propõe a investigar a relação dos treinamentos ambientais em empresas com um sistema de gestão ambiental implementado e o desempenho do Sistema de Gestão Ambiental. Investigou-se as etapas de realização do Treinamento Ambiental baseadas no Planejamento, Execução e Avaliação para constatar se essas podem se relacionar com o Desempenho Ambiental. Com base no arcabouço teórico, foi desenvolvido um modelo de análise que estabelece as relações entre os construtos a serem estudados. Para atingir os objetivos, foram desenvolvidos questionários e utilizadas escalas para mensuração dos construtos envolvidos e, como método de análise, utilizou-se a Modelagem de Equações Estruturais. A amostra foi composta por 105 respondentes atuantes em empresas certificadas ISO 14001 ou que não são certificadas mas que possuíam um mínimo de estrutura de um sistema de gestão ambiental. Os resultados obtidos na análise apresentaram uma forte relação entre planejamento do treinamento ambiental, execução do treinamento ambiental, avaliação do treinamento ambiental e o desempenho ambiental, explicando o que as referências teóricas apontavam no momento da elaboração do modelo de análise. Constatou-se uma relação positiva do Planejamento com a Execução e da Execução com o Desempenho, potencializado pela ação mediadora da Avaliação de Treinamento Ambiental. Concluiu-se que o arcabouço teórico forneceu recursos para o estabelecimento de um modelo capaz de explicar a relação entre treinamento ambiental e desempenho ambiental. Tal estudo, além de contribuir com as teorias relacionadas ao treinamento ambiental e desempenho ambiental, apresenta para as empresas, gestores ambientais e profissionais de recursos humanos a importância da aplicação sistêmica dos programas de treinamento ambiental, partindo do planejamento, seguindo para a execução e avaliação do mesmo e confirma o seu papel estratégico dentro da organização e reforça a importância da avaliação do treinamento ambiental pelo seu papel mediador no reforço dos resultados em desempenho ambiental, a partir do treinamento ambiental.

As a result of the ongoing worldwide pandemic of coronavirus disease the Swedish colleges, adult schools and high schools closed and switched to distance education. Beside the pandemic a report from the Teachers' Union was published in which it was found that many teachers are dissatisfied with the learning management systems used. The digitization of the school thus became a highly relevant area during this time. The purpose of this essay is to investigate the municipal adult education teacher's experience and use of learning management systems and thereby highlight what they see for challenges and opportunities with the learning management systems and if it has an impact on the actual usage. This paper is expected to respond to how teachers in Swedish municipal adult education feel that it is to work with learning management systems. To answer the question, a qualitative starting point is used, where semi-structured interviews have been used. In this study, the theoretical model UTAUT is used to analyze the result. The four constructs from UTAUT are used to categorize and identify the teachers' experiences, to better answer our research question. Ten municipal adult education teachers from four different schools in Västra Götaland, Sweden participated in the study. In the study, we could see that the most common area of use for the learning management system seems to be to communicate and to make materials accessible to students between classes. In addition, we could see that the teachers felt that their level of technical experience were somewhere between medium and high, all had some type of education and training in how to use learning platforms, however, more teachers described that there was a need for more education among colleagues. Advantages of learning management systems that most teachers described were increased efficiency, communication and accessibility, disadvantages that teachers described were legal security, integration, compliance with law and feedback. In general, the teachers seem more positively attuned to the platforms than negative. From the UTAUT model, we could see that all factors affect the teacher's intention and the actual use of the platform positively, however, some parts of the effort expectancy can negatively affect the teacher's intention to use. / I takt med coronautbrottet som startade i Kina och spred sig till stora delar av världen blev resultatet att svenska högskolor, vuxenskolor och gymnasium stängdes ner och gick över till ren distansutbildning. Parallellt med coronautbrottet publicerades en rapport från Lärarförbundet där det hade visat sig att många lärare är missnöjda med de digitala lärplattformar som används. Digitaliseringen av skolan blev därmed ett högt aktuellt område under denna tid. Syftet med denna studie är att undersöka komvuxlärarens upplevelse av digitala lärplattformar och därmed lyfta fram vad de tycker finns för olika för- och nackdelar samt vad som påverkar den faktiska användningen. Denna studie förväntas svara på hur lärare i svensk kommunal vuxenutbildning upplever att det är att arbeta med digitala lärplattformar. För att besvara frågeställning används en kvalitativ utgångspunkt, där semistrukturerade intervjuer genomfördes. I studien används den teoretiska modellen UTAUT för att analysera resultatet. Kärnfaktorerna från UTAUT används för att kategorisera och identifiera lärarnas upplevelser, för att bättre besvara frågeställningen. I studien deltog tio komvuxlärare från fyra olika skolor i Västra Götaland. I studien kunde vi se att det vanligaste användningsområdet för en digital lärplattform verkar vara att kommunicera och för att göra material tillgängligt för eleverna mellan lektionstillfällen. Utöver detta kunde vi se att lärarna ansåg att de befann sig någonstans mellan medel och hög nivå gällande teknisk kunskap, samtliga hade haft någon typ av utbildning och fortbildning i hur de kan använda digitala lärplattformar, dock beskrev flera lärare att det fanns ett behov av mer utbildning bland kollegorna. Fördelar med digitala lärplattformar som de flesta lärare beskrev var ökad effektivitet, kommunikation och tillgänglighet, nackdelar som lärarna beskrev var rättssäkerhet, integration, förenlighet med lag, och feedback. Överlag verkar lärarna mer positivt inställda till plattformarna än negativt. Utifrån UTAUT-modellen kunde vi se att samtliga faktorer påverkar lärarens intention till och den faktiska användningen av plattformen positivt, dock kan vissa delar i förväntad ansträngning kan påverka lärarens intention till användning negativt.
