Segelström, Fabian. "Service Design and Cultural Expectations on Services : Applying Hofstede's Cultural Dimensions to Services." Thesis, Linköping University, Department of Computer and Information Science, 2008. http://urn.kb.se/resolve?urn=urn:nbn:se:liu:diva-15536.
Full textAbstract:
<p>The notion of service design as a design field has emerged during the last 10-15 years and seems to be growing more and more; a 2007 textbook on interaction design states: “The new frontier of interaction design is services” (Saffer, 2007, p. 174). Since the field is so young, there still are areas which hardly have been explored. One of these is cultural effects on service expectations. This thesis aims to help to fill in the knowledge gap by applying a model of cultural differences. The model used is the one developed by Geert Hofstede, which has been proved to be valid within a large number of varyingfields. This was done through the research question “Is Hofstede’s model applicable to service design in general, and individualization of services in particular?”.</p><p>The question was explored through two parallel research processes; a quantitative questionnaire distributed via the web and a qualitative evaluation of 47 different service web sites. The qualitative evaluation was done through a new method called Cultural Walkthrough. Four key countries were chosen; the questionnaire was aimed at natives of these countries and the web sites all came from these countries. The countries in question were Germany, India, the United Kingdom and the USA.</p><p>The results indicate that Hofstede’s model can’t be applied to service design straight off. Neither can they be used as a basis to deem the want for the possibility to individualize services, which seems to be dependent on the individual. The results indicate a large number of interesting questions for further research.</p>

Full textAbstract:
Abstract. The growing age of populations brings widespread problems for a range of services, including health care services. Another challenge is the areas of dispersed settlement and decreasing population in rural areas. Urbanization and movement to the larger cities after employment, education, and services has led to decreasing the services in the remote areas even further. In the changing needs of the requirements and challenges of health care entities the use of mobile health care services may provide many benefits to the systems to develop flexible and adjustable health services to citizens. With the help of mobile health care services, the requirements of ever-changing service needs may be responded more efficiently than traditional onsite health care centers.
The purpose of this study is to understand the opportunities of user-centric service design and practices in the design processes of mobile health care services. In the future, mobile health care services may potentially be a medium for implementing the health and social service delivery as one of the standard mediums in order to reduce inconsistencies between habitant areas in Finland. By designing user-centric services with methods that leave room for ongoing development and improvement of mobile health care services.
The nature of the study is a qualitative case study. The research phenomenon is approached by semi-structured interviews, to define practicalities in the planning of a mobile health care services. The target group of the interview is particularly chosen participants from representative organizations from both private and public health sector.
The results of the study confirm the adaptability of user-centric service design in mobile health care services. It also reveals many practical aspects regarding the design process and the possibilities in co-design activities. More precisely, this study suggests that the user of the service can be included in all stages of service design process of mobile health care services in several ways — from defining the need to the implementation and ongoing development. The user-centricity in the context of this study means the users of the service that are involved in the service operations along its way — including employees and other encounters to the service.
The results of the study contribute to the model of service design by assessing its suitability to designing mobile health care services with user-centric approach, and gathering concrete practices of those methods.

Full textAbstract:
Recently, infotainment system has been used in the majority of new cars. It is considered as one of the car’s specifications. Nowadays, the consumers become bored from using the traditional infotainment systems because these systems are customized for the driver and disregard the passengers who want to be able to access the Internet and keep in touch with their friends any time they want besides getting entertained through watching movies and listening to the music. This study illustrates the portal design and the features of a new infotainment system that serves three kinds of users: drivers, passengers, and children. Moreover, this system adds a new feature which allows the users to share the information, such as locations and multimedia contents, and chatting between cars using VANET services. In addition, combines many features of some famous cars’ infotainment system to be in a single system and provide the passengers with some important services such as touristic services and health and safety services. While designing in car infotainment system, there are some constraints that aim to increase drivers and passengers safety in the same time decrease drivers distraction besides offering some entertainment and provide the needed information. Therefore, this paper studies some important guidelines that should be followed in designing the user interface of any infotainment system. Furthermore, we demonstrate the three phases of the design process: discovery phase, design phase and implementation. Using the collected data we designed a first mockup prototype that we submitted for some users’ evaluation. Some problems were spotted and corrected. This resulted in the development of a first functional prototype that was implemented in iOS. This design was tested as well. We finally propose an improved version of the interface and we test it in simulation using a tablet (iPad). The different prototypes will be exposed in this document along qualitative (satisfaction) and quantitative (time) results of their usability. These results are encouraging and showed the validity of our approach.

Full textAbstract:
Corporations and government agencies that use Avatars claim there are substantial benefits for using them in their respective organizations; including 24/7 service availability, quick answers without a phone queue, and improved consistency in the responses provided. “There are also potential cost savings by having an Avatar answering questions compared to using personnel” (Lind and Salomonson, 2006). However, these benefits may not be great enough as the lack of possible human communication may lead to alienation between individuals and organisations. Furthermore, a robot may “miss out” on business opportunities that a human would act on. A robot will not hear and understand nuances in speech, with the risk that a potentially problematic situation may not be adequately resolved, leading to dissatisfaction with products and services delivered. Many companies measure the satisfaction with Avatars by analysing question and answer logs to see if the Avatar appears to give satisfactory answers. Few of these companies have actually asked their customers (e.g. IKEA and SAS until recently) what they really feel about the quality of the answers they receive. User Centered Design, Participatory Design and other methods are the preferred ways of developing such systems, but these do not include all stakeholders. This thesis addresses this exclusion of all stakeholders by applying a co-design research approach for developing avatars for e-Services.Case studies from Mark Municipality, Sweden and Scandinavian Airlines Systems (SAS) are presented in this thesis showing how improvements of service quality aspects with Avatars can be managed by applying a four-step Co-Design research approach. From the first step of Co-Design, through interviews, log analysis and a channel survey, findings show that the failed dialogues with Avatars Eva (SAS) and Elin (Mark) are mainly concerned with five factors: interactivity; dialogue capability; consistency; knowledge; and synonyms. In the second step of carrying out customer workshops, a number of ideal scenarios are suggested for the Avatars to perform better. In the third step, SAS decision makers decided to implement the first three scenarios: Eva’s synonyms, knowledge and consistency. Mark decision makers decided to shut down their Avatar Elin, as they did not believe they had the necessary resources. In the fourth step, another channel survey was carried out for SAS as well as a new log analysis in order to know the impact of the redevelopment of the above three scenarios. An important result of the study was that the company adopted the continuous use of Co-Design as an approach to continuous improvement of the service quality performed by the Avatar Eva. This, for example, led to an increase of 14 percentage points on the users overall satisfaction level. The results also open a new set of questions framing the relation and transformation between Co-Design as a research approach for knowledge creation and Co-Design as a method for innovation and service quality improvements. This thesis also presents an Extended Co-Design Model, which illustrates how Co-Design inspires SAS staff. In addition, the staff of the supplier of the Avatar use it for other functions within and without SAS.

Previous issue date: 2012-06-29<br>Nenhuma<br>A globalização apresenta-se como um processo influenciador das dinâmicas sociais, alterando a ordem de um contexto previsível e estático até então estabelecido, para um cenário dinâmico, fluido e de complexidade sem precedentes. Na sociedade contemporânea, a importância do setor de serviços é crescente, respondendo por grande parte da economia dos países, tornado assim esse mercado cada vez mais competitivo. Acompanhar as constantes mudanças no setor e o nível de exigência dos consumidores traz a necessidade de uma prática de projetação de serviços mais adequada ao atual contexto. A discussão é estabelecida a partir do entendimento de que o desenvolvimento de serviços inovadores pode ser obtido através de projetos orientados pelo design. Assim, este estudo delimita-se em, a partir de um olhar do Design Estratégico, contextualizar e avaliar a aplicação das ferramentas da disciplina de design de serviços no desenvolvimento de novos serviços hospitalares. A metodologia utilizada no estudo é constituída por revisão bibliográfica e estudo exploratório a partir de uma pesquisa ação, contemplada por meio da aplicação metodológica em um caso piloto. Teve-se como premissa que, ao explorar caminhos apontados por autores de design estratégico e design de serviços, através da exploração de seus conceitos e utilização das suas metodologias e ferramentas, fosse possível ter uma perspectiva projetual mais adequada, capaz de criar experiências diferenciadas, alcançando uma abordagem de serviços mais centrada nos usuários. Os resultados apontam que serviços projetados por essa lógica apresentam resultados diferenciados, e que sua implementação interfere e afeta a estrutura organizacional vigente.<br>Globalization presents itself as a process of influencing social dynamics, changing the order of a predictable and static context previously established to a dynamic scenario, of unprecedented fluidity and complexity. In contemporary society, the importance of the service sector is growing, accounting for much of the economy of countries, which make this an increasingly competitive market. Keeping pace with continuing changes in the sector and the level of consumer demand bring the need of a practice of design services best suited to the current context. The discussion is established based on the understanding that the development of innovative services can be obtained through projects oriented by service design. From the perspective of Strategic Design, this study consists of contextualize and evaluate the application of the tools of the discipline of service design in the development of new hospital services. The methodology of this study consists in bibliographic review and exploratory study based on research action, contemplated by the methodological application in a pilot case. The premise of this study was that, by exploring ways pointed out by authors of strategic design and service design, and exploring their concepts and use of methodologies and tools, it would be possible to have a more appropriate project perspective, able to create unique experiences, achieving a service approach more focused on the users. The results show that services designed from this logic have different results, and that its implementation interferes and affects the current organizational structure

Full textAbstract:
Dans une société où l’économie des services est en croissance, le design de services innovants revêt une importance cruciale. Mais comment la valeur de ces services est-elle conçue ? La thèse interroge la manière dont s’élabore la valeur immatérielle et expérientielle des services innovants et plus particulièrement le rôle des représentations visuelles pour rendre présent un service qui n’existe pas encore. Elle vise pour cela à répondre à deux questions de recherche : Quelles sont les différentes épreuves de valuation qui structurent le processus de conception de services ? Quels sont les rôles des représentations, en tant que valuation devices, dans ces épreuves ? Le travail repose sur l’étude de deux cas complémentaires de design de service : un terrain pédagogique et un terrain industriel. Adoptant une approche en termes de valuation, nous considérons le processus de conception de services comme un processus collectif où se jouent des conflits, des dynamiques d’intéressement et des compromis sur la valeur du service futur, que nous proposons de modéliser. Notre modèle montre que la valeur des services s’élabore au cours d’un processus de valuation collective qui s’explicite et se résout dans des épreuves de valuation caractérisées par quatre éléments : les objets et les registres des valuations, les acteurs en interaction et les opérations de valuation effectuées. Nous montrons comment, dans ces épreuves, les représentations viennent supporter, stimuler et, parfois, entraver le travail collectif sur la valeur effectué par les acteurs. Nous soulignons à quel point leurs caractéristiques matérielles ont des effets sur les épreuves de valuation (notamment en termes de types, de finition, de vraisemblance et d’équipement). Ces différentes observations nous conduisent à proposer deux régimes de travail collectif sur la valeur : un régime de convergence caractérisé par l’alignement des valuations des acteurs où les représentations constituent des catalyseurs de valeur ; un régime de démonstration, marqué par l’enrôlement de nouveaux acteurs où les représentations constituent des démonstrateurs de valeur. Nos résultats permettent de modéliser le travail sur la valeur en montrant que c’est par et dans ces épreuves, autour et dans les représentations visuelles que s’élaborent et s’éprouvent à la vois la valeur multiple, immatérielle et expérientielle du service futur et le réseau d’acteurs qui le portent. Ce modèle vient enrichir le champ du design de services et du rôle des représentations dans la conception. Il souligne en outre le rôle critique et stratégique des représentations dans la création de valeur des services et fournit des clés de compréhension et de pratiques aux designers et managers de l’innovation de services<br>In our growing service economy, designing innovative services is critical. But how is the value of innovative services designed? Our thesis questions how the immaterial and experiential value of innovative services is shaped, and especially the role of visual representations in making present a service that doesn’t exist yet. We aim at answering two research questions: what are the different valuation tests that structure the service design process ? What are the different roles of visual representations, as valuation devices, in those valuation tests? Our study is based on two complementary case studies of service design projects : the first one is a pedagogical case, the second one is an industrial case. We adopt an approach in terms of valuation and consider the service design process as a collective process, in which actors express conflicts and elaborate compromises on the value of future servicesOur model shows that the value of services is shaped through a collective valuation process that is structured by valuation tests. Those valuation tests are characterized by four dimensions : the objects and registers of valuations, the actors interacting and the valuation operations performed. We show how representations support, stimulate and, sometimes, hinder the collective work on value. We highlight how their material characteristics have an impact on the valuation tests (in particular with regard to their types, their level of polishing, their level of verisimilitude and their equipment). These observations lead us to suggest two types of collective work on value: a convergence one, in which actors align their valuations and in which representations are value catalysts ; a demonstration one, in which actors try to enroll new actors in the network and in which representations are value demonstrators. Our results allow us to model the work on the value of future services: they show how this value is shaped by and in valuation test, in which visual representations are both tools for constructing the value of future services and the tools that support the actors’ social and political interactions on this value. Our model thus contributes to a better understanding of service design and of the role of visual representations in the design process. We highlight the critical and strategic part of visual representations in the value creation of services. Hence, we provide services designers and service innovation managers with keys for understanding and practicing service innovation

How might we through emotional service design investigate how to support people in coping with social isolation by enabling for opportunities to be alone together? This is the research question this interaction design bachelor thesis, through applying theories of emotional and service design, has been aiming towards investigating. What is presented in the work is a merge of the terms, emotional service design. In addition to this, a service to help improve its user’s well-being and ability to cope with the effects of an isolated stay-at-home life is proposed.The conducted research has taken a qualitative approach, using methods of semi-structured interviews, affinity-diagramming, cultural probes, co-creative workshops and prototype testing, insights indicating that loneliness can be combated through two main ways: by finding an activity-based escape or by connecting with people or others. What is argued for is the importance of keeping emotional reactions in mind when designing for experiences.

How can coaching services encourage user engagement? The objective of this thesis has been to conduct research with a service design approach of what changes can be made to a service to further engage and motivate users. The already existing service provided by Scania called Driver Coaching is used as a case study. The thesis contributes to research by exploring how coaching services can implement gamification aspects in its customer journey. Using said case study as an example, user studies were conducted and resulted in an extensive list of insights and user needs. A gamification framework called Octalysis was used to locate what aspects of the service that could be changed in order to increase user motivation. The user needs and the lacking core drives in the current Octalysis were connected during the ideation phase. Connecting the gamification theory with the service design case study, a design proposal took form. In this case study, the design proposal is a modular concept with five different components that can be implemented in the service on their own or all together. Even though this design proposal is specific to the case study, the process of using the gamification theory and methods could be applied to other cases.

Bai, Hao. "Scheduling Design for Advance Virtual Network Services." Scholar Commons, 2016. http://scholarcommons.usf.edu/etd/6461.
Full textAbstract:
Network virtualization allows operators to host multiple client services over their base physical infrastructures. Today, this technique is being used to support a wide range of applications in cloud computing services, content distribution, large data backup, etc. Accordingly, many different algorithms have also been developed to achieve efficient mapping of client virtual network (VN) requests over physical topologies consisting of networking infrastructures and datacenter compute/storage resources. However as applications continue to expand, there is a growing need to implement scheduling capabilities for virtual network demands in order to improve network resource utilization and guarantee quality of service (QoS) support.
Now the topic of advance reservation (AR) has been studied for the case of scheduling point-to-point connection demands. Namely, many different algorithms have been developed to support various reservation models and objectives. Nevertheless, few studies have looked at scheduling more complex "topology-level'' demands, including virtual network services. Moreover, as cloud servers expand, many providers want to ensure user quality support at future instants in time, e.g., for special events, sporting venues, conference meetings, etc.
In the light of above, this dissertation presents one of the first studies on advance reservation of virtual network services. First, the fixed virtual overlay network scheduling problem is addressed as a special case of the more generalized virtual network scheduling problem and a related optimization presented. Next, the complete virtual network scheduling problem is studied and a range of heuristic and meta-heuristic solutions are proposed. Finally, some novel flexible advance reservation models are developed to improve service setup and network resource utilization. The performance of these various solutions is evaluated using various methodologies (discrete event simulation and optimization tools) and comparisons made with some existing strategies.

Murphy, Brendan Joseph. "Multimedia services in a distributed office." Thesis, Loughborough University, 1990. https://dspace.lboro.ac.uk/2134/13977.
Full textAbstract:
This thesis is concerned with the provision of multimedia services (involving voice, video, text and graphics) in an office environment. The office of the future is expected to comprise a heterogeneous collection of workstations and multimedia components (including fileservers, voice and video codecs, document scanners, laser printers, etc) interlinked by a high speed (digital) local area network. Every office is likely to have one or more connections to a public Integrated Services Digital Network (ISDN) providing integrated access (involving various types of traffic) to a very large number of subscribers. This thesis considers general issues relating to the design of such an office. Particular attention is given to the problem of the integration of media both at the network and user levels. Much of this discussion draws on practical experience gained during the Alvey Unison Project in which experimental multimedia offices were interconnected using a pilot ISDN. The architecture of the Unison network is discussed with particular reference to its suitability for the support of multimedia services. The bulk of this thesis is devoted to a description of the design and implementation of a number of prototype multimedia applications, and to an evaluation of their performance over the network. The handling of slow-scan video and high resolution images have been particular areas 01 interest. Much emphasis is placed on the problem of control in a distributed environment, and a model is presented for the management of control based on the use of a directory-like service. This model also provides a mechanism for locating an office service based on the name of the user to whom it belongs.

Full textAbstract:
During the past decade service-orientation has become a popular design paradigm, offering an approach in which services are the functional building blocks. Services are self-contained units of composition, built to be invoked, composed, and destroyed on (user) demand. Service-oriented systems (SOS) are a collection of services that are developed based on several design principles such as: (i) loose coupling between services (e.g., inter-service communication can involve either simple data passing or two or more connected services coordinating some activity) that allows services to be independent, yet highly interoperable when required; (ii) service abstraction, which emphasizes the need to hide as many implementation details as possible, yet still exposing functional and extra-functional capabilities that can be offered to service users; (iii) service reusability provided by the existing services in a rapid and flexible development process; (iv) service composability as one of the main assets of SOS that provide a design platform for services to be composed and decomposed, etc. One of the main concerns in such systems is ensuring service quality per se, but also guaranteeing the quality of newly composed services. To accomplish the above, we consider two system perspectives: the developer's and the user's view, respectively. In the former, one can be assumed to have access to the internal service representation: functionality, enabled actions, resource usage, and interactions with other services. In the second, one has information primarily on the service interface and exposed capabilities (attributes/features). Means of checking that services and service compositions meet the expected requirements, the so-called correctness issue, can enable optimization and possibility to guarantee a satisfactory level of a service composition quality. In order to accomplish exhaustive correctness checks of design-time SOS, we employ model-checking as the main formal verification technique, which eventually provides necessary information about quality-of-service (QoS), already at early stages of system development. ~As opposed to the traditional approach of software system construction, in SOS the same service may be offered at various prices, QoS, and other conditions, depending on the user needs. In such a setting, the interaction between involved parties requires the negotiation of what is possible at request time, aiming at meeting needs on demand. The service negotiation process often proceeds with timing, price, and resource constraints, under which users and providers exchange information on their respective goals, until reaching a consensus. Hence, a mathematically driven technique to analyze a priori various ways to achieve such goals is beneficial for understanding what and how can particular goals be achieved. This thesis presents the research that we have been carrying out over the past few years, which resulted in developing methods and tools for the specification, modeling, and formal analysis of services and service compositions in SOS. The contributions of the thesis consist of: (i)constructs for the formal description of services and service compositions using the resource-aware timed behavioral language called REMES; (ii) deductive and algorithmic approaches for checking correctness of services and service compositions;(iii) a model of service negotiation that includes different negotiation strategies, formally analyzed against timing and resource constraints; (iv) a tool-chain (REMES SOS IDE) that provides an editor and verification support (by integration with the UPPAAL model-checker) to REMES-based service-oriented designs;(v) a relevant case-study by which we exercise the applicability of our framework.The presented work has also been applied on other smaller examples presented in the published papers.<br>Under det senaste årtiondet har ett tjänstorienterat paradigm blivit allt-mer populärt i utvecklingen av datorsystem. I detta paradigm utgör så kallade tjänster den minsta funktionella systemenheten. Dessa tjänster är konstruerade så att de kan skapas, användas, sammansättas och avslutas separat. De ska vara oberoende av varandra samtidigt som de ska kunna fungera effektivt tillsammans och i samarbete med andra system när så behövs. Vidare ska tjänsterna dölja sina interna implementa-tionsdetaljer i så stor grad som möjligt, samtidigt som deras fulla funktionalitet ska exponeras för systemdesignern. Tjänsterna ska också på ett enkelt sätt kunna återanvändas och sammansättas i en snabb och flexibel utvecklingsprocess.En av de viktigaste aspekterna i tjänsteorienterade datorsystem är att kunna säkerställa systemens kvalitet. För att åstadkomma detta ärdet viktigt att få en djupare insikt om tjänstens interna funktionalitet, i termer av möjliga operationer, resursinformation, samt tänkbar inter-aktion med andra tjänster. Detta är speciellt viktigt när utvecklaren har möjlighet att välja mellan två funktionellt likvärda tjänster somär olika med avseende på andra egenskaper, såsom responstid eller andra resurskrav. I detta sammanhang kan en matematisk beskrivning av en tjänsts beteende ge ökad förståelse av tjänstemodellen, samt hjälpa användaren att koppla ihop tjänster på ett korrekt sätt. En matematisk beskrivning öppnar också upp för ett sätt att matematiskt resonera kring tjänster. Metoder för att kontrollera att komponerade tjänstermöter ställda resurskrav möjliggör också resursoptimering av tjänster samt verifiering av ställda kvalitetskrav.I denna avhandling presenteras forskning som har bedrivits under de senaste åren. Forskningen har resulterat i metoder och verktyg föratt specificera, modellera och formellt analysera tjänster och sammansättning av tjänster. Arbetet i avhandlingen består av (i) en formell definition av tjänster och sammansättning av tjänster med hjälp avett resursmedvetet formellt specifikationsspråk kallat Remes; (ii) två metoder för att analysera tjänster och kontrollera korrektheten i sammansättning av tjänster, både deduktivt och algoritmiskt; (iii) en modell av förhandlingsprocessen vid sammansättning av tjänster som inkluderar olika förhandlingsstrategier; (iv) ett antal verktyg som stödjer dessa metoder. Metoderna har använts i ett antal fallstudier som är presenterade i de publicerade artiklarna.<br>Contesse

Full textAbstract:
La création de la valeur et l’amélioration de la qualité dans le domaine automobile ne sont plus limitées à la commercialisation de véhicules innovants à l’écoute du marché avec des délais raccourcis de conception mais doivent être progressivement étendues à la conception performante des services associés tels que les garanties et le service après-vente. Cette thèse définit la conception des services comme une conception de l’offre des services, des processus des services et de la réalisation des services. Elle traite plus profondément de la conception des processus du service après-vente Renault et propose une nouvelle approche innovante d’aide à la conception basée sur la modélisation des processus organisationnels, la simulation de flux, la CAO et la visualisation 3D afin de favoriser les tests avant déploiement et la collaboration entre les différents intervenants (marketers, experts qualité, logisticiens, implanteurs, acteurs SI et décideurs stratégiques). L’objectif final de ce maquettage numérique des services ou de cette Conception de Service Assistée par Ordinateur (CSAO) est de diminuer les coûts de conception, d’améliorer la qualité, d’aider à définir les objectifs et les normes de qualité (temps de service, temps d’attente, taux d’occupation des ressources, surfaces dédiées et agencement) et de sélectionner mutuellement les meilleurs compromis. De plus, cette thèse montre comment la conception des processus peut impacter la conception de l’offre et comment la conception de la réalisation du service avec le client peut être modélisée par la simulation comportementale. Enfin, elle caractérise la logistique pour le service après-vente et identifie des pistes de progrès dans la conception des systèmes d’information<br>Value creation and quality strengthening in the automotive industry are no longer limited to supply marketable innovative cars with shortened lead-times but have to be extended gradually to efficient design of associated services such as extended warranties and after sale services. `This thesis defined Service Design as a Concept Service Design, Service Process Design and Production Service Design. It tackles more deeply with the Renault After Sale Service Process Design and proposes a new innovative aided design approach based on Business Process Modelling, flow simulation, CAD and 3D Visualisation in order to foster what-if scenarios and collaboration within all the professionals ( marketers, quality experts, logisticians CAD specialists, IT professionals and top managers). The aim of this « Service Digital Mock up » or « Computer Service Aided design » is to decrease design costs, leverage quality and help define objectives, quality norms ( service time, waiting time, resource workload, dedicated areas and layout) and select mutually the best compromises. Besides, this thesis show how Process Design can impact designing new Services Offers and how Service production with the clients can be described by behavorial simulation.

Full textAbstract:
Dans ce travail de recherche nous nous intéressons à un objet particulier : la conception de lignées de services complexes. Nous étudions cet objet dans un contexte particulier lui aussi, celui de la Défense en Europe. Chacun de ces termes est porteur d’interrogations : que sont les services dans l’armement ? ; en quoi sont-ils complexes ? ; qu’est-ce qu’une lignée de service ? Ces services se caractérisent principalement par une durée de la relation s’inscrivant dans le temps long, de l’ordre de plusieurs décennies, sans commune mesure avec les services le plus souvent étudiés. La complexité de l’écosystème d’acteurs – mêlant public et privé – ainsi que celle intrinsèque aux produits et systèmes d’armement – systèmes de missiles, avions de combat, sous-marins nucléaires, etc. – contribuent également à l’originalité et la valeur de notre objet d’étude. La lignée, issue du monde de la conception innovante de produits, se caractérise sous deux dimensions en interaction : la succession de projets et l’accumulation des connaissances. Là encore, ces deux dimensions sont souvent absentes de la recherche sur les services. Dans l’optique de conception qui est la nôtre, les premières questions en appellent deux autres : comment représenter de tels services ? ; et comment organiser les fonctions de conception et notamment la création des connaissances nouvelles, innovantes, nécessaires à la co-conception et à la co-production du service par l’ensemble des acteurs ? Nous avons mené cette recherche au plus près du terrain. Intégré durant trois ans au sein d’un grand groupe Européen de défense (au titre d’une convention CIFRE), directement impliqué dans différents projets de conception de services innovants, nous avons été confronté d’un point de vue pratique autant que théorique à ces questions. Les travaux s’articulent autour de ces projets ainsi que d’une étude de cas comparative entre des projets de service de défense en France et au Royaume-Uni. À ce titre, le doctorant a effectué une période de six mois en tant que visiting PhD à l’Université de Cambridge. Quoi qu’ancrée dans un secteur particulier, notre recherche est porteuse d’enseignements à la portée plus générale pour la recherche comme pour les praticiens. À la fois Issu des cas et utilisé comme grille de lecture de ces mêmes cas, l’outil ReADy – pour Référentiel d’Analyse Dynamique de la valeur de service – est le principal apport conceptuel de nos travaux. Par la tension qu’il introduit entre ses deux composantes que sont le concept et le contrat, il contribue à représenter et concevoir la succession des projets de service. Par la notion de communauté d’apprentissage, en lien avec ReADy, nous mettons en lumière les principaux mécanismes de la création des connaissances nécessaires à la mise en place d’une lignée de services complexes<br>In this research we look at a singular object: lineages of complex services design. We study this object in a context singular in itself, which is the European Defence Sector. Each of the above terms raises questions: what are services in the defence sector? What makes them complex? What is a service lineage? The services we look at are characterised by the duration of the relationship, to be counted in decades, without measure with the ones most commonly studied. The complexity of the ecosystem of actors – comprising public and private sectors – and that of the underlying products and systems – e.g. missiles systems, fighter aircrafts or nuclear submarines – also contribute to the originality and the value of the object of our research. The concept of lineage, rooted in the innovative design of products, is best described by the interplay between the succession of projects and the accumulation of knowledge. Here again, both dimension are most often overlooked in service research. In our perspective of service design, our first questions call for two others: how to describe such services? and how to organise the design functions in such manner that new knowledge is created and shared to allow co-design and co-production of the service by the whole ecosystem of actors?Our research was conducted in close proximity with the actual field. Fully integrated within the organisation of a major player in the European defence sector (as per a CIFRE convention), the researcher was hands-on with several innovative service design projects and confronted with the above questions on both theoretical and practical perspectives. These projects are at the heart of our research, together with a comparative case study of defence services in France and the United-Kingdom. To that effect, a six month visiting PhD period was conducted in the University of Cambridge.Although being rooted in a singular context, our research bears more general insights for academia and practitioners alike. Coming from the case material and used to shed light on it as well, our ‘Dynamic Analysis of service value Referential ‘, dubbed ReADy, is the main theoretical contribution of our work. By the tension it introduces between its two components – the concept and the contract – it contributes to the description and design of the successions of service projects. With the concept of ‘learning communities’, together with ReADy, we shed light on the main knowledge creation mechanisms at work when implementing a lineage of complex services

Full textAbstract:
<p>This paper is a study and comparison between the two Wireless LAN (WLAN) standards HiperLAN/2 and IEEE 802.11a. WLANs are used instead or together with ordinary LANs to increase mobility in for example an office. HiperLAN/2 is an European standard developed by ETSI and the IEEEs standard is American. </p><p>A WLAN-card consists roughly of a Medium Access Control (MAC), Physichal layer (PHY) and an antenna. The antenna is the same for the different standards. </p><p>Both standards operates at 5.4 GHz with a maximum transmission rate at 54 Mbit/s and they use OFDM to modulate the signal. This means that the physical layer in the two standards is similar. </p><p>The differences between the standards are in the Medium Access Control (MAC) layer. HiperLAN/2 has a much more complex MAC since it is developed with the starting point in cellular phones. Therefore this MAC is not very similar to ETHERNET that is the protocol used by regular network. On the other hand it is built to be compatible with cellular phones and other applications. </p><p>The 802.11a MAC is very much the same as in the 802.11b standard that is the most used standard at present. The difference is that 802.11a can send at much higher data rates. This MAC is build with starting point in ETHERNET so it has a similar interface to the computer. This makes it less complex. </p><p>The different MACs can provide different services. The greatest difference is that 802.11a can use a distributed send mode where any STA can send if the medium is idle. This reminds a lot of ETHERNET but they use different methods to sense if the medium is idle. In HiperLAN/2 are all transmissions scheduled by the AP. 802.11a can operate in a similar way but at the moment this mode is not as fully developed as in HiperLAN/2. There are working groups in IEEE that works toward an improvement of 802.11a so it can use queues with different priorities, this is already implemented in HiperLAN/2. </p><p>Another important issue in wireless environment is security. Both standards use encryption to protect their messages. The difference is that HiperLAN/2 changes their encryption key for every connection where 802.11a uses the same key the whole time. This gives HiperLAN/2 a better security with todays standard but thereare working groups dealing with implementing key-exchange functions and Kerberos use in 802.11a. Chapter 8 is a description of a program that we developed in C++. The program is used to monitor the different registers and ports a WLAN-card use. It is written for a 802.11b card and should be used together with Windows 2000. The source code can be found in appendix C.</p>

Full textAbstract:
<p>This project is a continuation of research work done by (Asif, 2009) which proposed an extended architecture of Mobile Student Information System (MSIS) to integrate the systems available for the students to provide student centric services on mobile devices. The architecture was developed by using Service Oriented Architecture (SOA) to provide services for collaboration and communication among the students or between students and the teachers. The mobile services are built by integrating MSIS to Twitter, Feed based systems and NTNU email system. The services have the potential to provide students an experience of a virtual environment of class, project work and discussion groups anytime-anywhere. The project has been carried out in accordance with design-science research model over a number of implementation and evaluation iterations. A user-driven evaluation of the MSIS service has been conducted among a diverse group of NTNU students. The utility as well as the usability of the system were evaluated by applying observational and empirical evaluation methods in a real-world environment at the university. The usability test identified few issues with the initial design of services, and received feedback for enhancements. The Mobile Service Acceptance Model (MSAM) has been used to examine the factors that are influential for user adoption of mobile services in the light of this project. The MSAM instrument measures different facets of a mobile information service, such as the perceived usefulness, ease of use, and usage intention. Our findings confirm that the utility of the student centric mobile services are perceived as high, and students would likely benefit from such kind of services. There is no doubt about the great potential for a service like MSIS and it is believed to be a useful addition to the existing systems.</p>

Full textAbstract:
The fast paced evolution of technology has changed the way people interact with service providers in a significant way; the introduction of new service delivery channels has mainly been based on technological advances rather than on customer needs. During the last 20 years the banks have extended their service offerings from just having the branch offices to the multichannel service delivery systems of today, including; phones, computers and smartphone apps. Previous research has concluded that there were many barriers for mobile banking to become a widespread service delivery channel for banks, such as technical limitations, trust issues and social obstacles. In order to understand the role of the smartphone in this multichannel ecology, a qualitative interview study was undertaken focusing on the customers’ perception of the bank. The results show that the choice of channel is dependent on personal characteristics, perceived risk, context and how the task itself is perceived. The results show that the current role of the smartphone is complementary to the other channels, providing the customer with basic banking services wherever they are; it supports the customer in the activity of managing ones private economy and providing the informant with the feeling of control. The results also include insights into the life of three customers and their interaction with their bank over the course of one month in the form of customer journey maps.

Benford, Steven David. "Research into the design of distributed directory services." Thesis, University of Nottingham, 1988. http://eprints.nottingham.ac.uk/11218/.
Full textAbstract:
Distributed, computer based communication is becoming established within many working environments. Furthermore, the near future is likely to see an increase in the scale, complexity and usage of telecommunications services and distributed applications. As a result, there is a critical need for a global Directory service to store and manage communication information and therefore support the emerging world-wide telecommunications environment. This thesis describes research into the design of distributed Directory services. It addresses a number of Directory issues ranging from the abstract structure of information to the concrete implementation of a prototype system. In particular, it examines a number of management related issues concerning the management of communication information and the management of the Directory service itself. The following work develops models describing different aspects of Directory services. These include data access control and data integrity control models concerning the abstract structure and management of information as well as knowledge management, distributed operation and replication models concerning the realisation of the Directory as a distributed system. In order to clarify the relationships between these models, a layered directory architecture is proposed. This architecture provides a framework for the discussion of directory issues and defines the overall structure of this thesis. This thesis also describes the implementation of a prototype Directory service, supported by software tools typical of those currently available within many environments. It should be noted that, although this thesis emphasises the design of abstract directory models, development of the prototype consumed a large amount of time and effort and prototyping activities accounted for a substantial portion of this research. Finally, this thesis reaches a number of conclusions which are applied to the emerging ISO/CCITT X. 500 standard for Directory services, resulting in possible input for the 1988-92 study period.

Catchpole, C. P. "Information systems design for the community health services." Thesis, Aston University, 1987. http://publications.aston.ac.uk/10620/.
Full textAbstract:
This system is concerned with the design and implementation of a community health information system which fulfils some of the local needs of fourteen nursing and para-medical professions in a district health authority, whilst satisfying the statutory requirements of the NHS Korner steering group for those professions. A national survey of community health computer applications, documented in the form of an applications register, shows the need for such a system. A series of general requirements for an informations systems design methodology are identified, together with specific requirements for this problem situation. A number of existing methodologies are reviewed, but none of these were appropriate for this application. Some existing approaches, tools and techniques are used to define a more suitable methodology. It is unreasonable to rely on one single general methodology for all types of application development. There is a need for pragmatism, adaptation and flexibility. In this research, participation in the development stages by those who will eventually use the system was thought desirable. This was achieved by forming a representative design group. Results would seem to show a highly favourable response from users to this participation which contributed to the overall success of the system implemented. A prototype was developed for the chiropody and school nursing staff groups of Darlington health authority, and evaluations show that a significant number of the problems and objectives of those groups have been successfully addressed; the value of community health information has been increased; and information has been successfully fed back to staff and better utilised.

Abdullah, Abdul H. "Accessing networked services : a user interface design problem." Thesis, Aston University, 1994. http://publications.aston.ac.uk/10669/.
Full textAbstract:
This research investigates the general user interface problems in using networked services. Some of the problems are: users have to recall machine names and procedures to. invoke networked services; interactions with some of the services are by means of menu-based interfaces which are quite cumbersome to use; inconsistencies exist between the interfaces for different services because they were developed independently. These problems have to be removed so that users can use the services effectively. A prototype system has been developed to help users interact with networked services. This consists of software which gives the user an easy and consistent interface with the various services. The prototype is based on a graphical user interface and it includes the following appJications: Bath Information & Data Services; electronic mail; file editor. The prototype incorporates an online help facility to assist users using the system. The prototype can be divided into two parts: the user interface part that manages interactlon with the user; the communicatIon part that enables the communication with networked services to take place. The implementation is carried out using an object-oriented approach where both the user interface part and communication part are objects. The essential characteristics of object-orientation, - abstraction, encapsulation, inheritance and polymorphism - can all contribute to the better design and implementation of the prototype. The Smalltalk Model-View-Controller (MVC) methodology has been the framework for the construction of the prototype user interface. The purpose of the development was to study the effectiveness of users interaction to networked services. Having completed the prototype, tests users were requested to use the system to evaluate its effectiveness. The evaluation of the prototype is based on observation, i.e. observing the way users use the system and the opinion rating given by the users. Recommendations to improve further the prototype are given based on the results of the evaluation.

Frascina, Anthony Cosimo. "The integration of hospital information systems through user centred design." Thesis, Sheffield Hallam University, 1994. http://shura.shu.ac.uk/3185/.
Full textAbstract:
The development of computer systems in UK hospitals has in recent years been focused on the provision of hospital-wide information systems, known as Hospital Information Support Systems (HISS). This development has been motivated by National Health Service reforms and a realisation that earlier fragmented systems were not meeting the requirements of clinical and nursing staff in the most effective way. Such systems were often developed by external, centralised agencies using systems analysis techniques appropriate to the development of information systems in product orientated organisations. However, the hospital ward, an environment existing at the 'sharp end' of health care, in which many diverse and non-computer related activities take place, presents the system designer with many of the classic problems with which the discipline of Human Computer Interaction (HCI) is concerned. Although a HISS has the potential to improve both the work conditions of clinical staff and the delivery of health care, this may be impeded by many of the common obstacles associated with the introduction of a large and complex computer system into a work environment where tasks are ill defined. This thesis reports on a project that is based upon the application of HCI methods to the health care environment and their contribution to the solution of the problems that such an environment presents. Requirements for the users' interface to the potential HISS are derived using a task analytic approach, involving Task Analysis for Knowledge Descriptions (TAKD). A prototype system has been designed and subsequently evaluated in a hospital ward. The contribution of TAKD to the design and its further applicability to the environment are assessed. The research represents an original application of a formal task analysis method to the design of ward based computer systems, and as such makes a valuable contribution to the areas of medical informatics and HCI. It shows that TAKD has real but limited applicability in this sphere, in that its use can lead to the design of more usable interfaces, while there is a need to combine it with methods aimed at broader systems design if these benefits are to accrue in the development of a HISS. The potential for the integration of task analysis with Design Rationale methods is also demonstrated.

Full textAbstract:
According to innovation literature, between 50% and 90% of innovations fail. An explanation for failing innovations is offered by scholars in the field of innovation resistance, who argue that it is more relevant to pay attention to the reasons why consumers reject an innovation, rather than learning about their motivations to adopt a new product or service. At the same time, previous marketing literature has devoted little attention towards design, despite its strategic importance and its role as a driver of innovation and competitive advantage. The purpose of this study was to investigate how companies perceive innovation resistance towards service innovations and how it is reflected in the service design. The major takeaways in this study revealed that companies were aware of all the barriers, except for social risk and perceived security risk. Furthermore, companies made most service design adaptations based on the usage and value barrier both prior and post launch. Also, although the tradition and norm barrier and image barrier were considered critical for an innovation’s success, companies did not change the service design accordingly. Finally, it was revealed that companies followed a hybrid approach of innovation, where more of a design-driven innovation strategy was used to generate innovation ideas and a user-centered approach was applied by involving consumers in pilot studies and listening to the consumer voices post launch.

Siddiqui, Mahboob-ul-Haq. "Performance measurement methodology for integrated services networks." Thesis, Loughborough University, 1989. https://dspace.lboro.ac.uk/2134/15430.
Full textAbstract:
With the emergence of advanced integrated services networks, the need for effective performance analysis techniques has become extremely important. Further advancements in these networks can only be possible if the practical performance issues of the existing networks are clearly understood. This thesis is concerned with the design and development of a measurement system which has been implemented on a large experimental network. The measurement system is based on dedicated traffic generators which have been designed and implemented on the Project Unison network. The Unison project is a multisite networking experiment for conducting research into the interconnection and interworking of local area network based multi-media application systems. The traffic generators were first developed for the Cambridge Ring based Unison network. Once their usefulness and effectiveness was proven, high performance traffic generators using transputer technology were built for the Cambridge Fast Ring based Unison network. The measurement system is capable of measuring the conventional performance parameters such as throughput and packet delay, and is able to characterise the operational performance of network bridging components under various loading conditions. In particular, the measurement system has been used in a 'measure and tune' fashion in order to improve the performance of a complex bridging device. Accurate measurement of packet delay in wide area networks is a recognised problem. The problem is associated with the synchronisation of the clocks between the distant machines. A chronological timestamping technique has been introduced in which the clocks are synchronised using a broadcast synchronisation technique. Rugby time clock receivers have been interfaced to each generator for the purpose of synchronisation. In order to design network applications, an accurate knowledge of the expected network performance under different loading conditions is essential. Using the measurement system, this has been achieved by examining the network characteristics at the network/user interface. Also, the generators are capable of emulating a variety of application traffic which can be injected into the network along with the traffic from real applications, thus enabling user oriented performance parameters to be evaluated in a mixed traffic environment. A number of performance measurement experiments have been conducted using the measurement system. Experimental results obtained from the Unison network serve to emphasise the power and effectiveness of the measurement methodology.

Inom vården kämpar man idag med ineffektiva arbetsprocesser och strama monetära tillgångar för att möta utmaningar som kommer med en allt äldre befolkning och de krav som detta ställer på vårdapparaten. Som ett svar dessa problem har detta examensarbetet fokuserat på att förbättra arbetsprocesser på ett akutsjukhus i Stockholmsregionen och göra dessa tids- och kostnadseffektiva samtidigt som man vill bibehålla en hög patientsäkerheten. Genom att kombinera Lean och tjänstedesignmetoder identifierades, efter observationer och intervjuer, icke-värdeskapande aktiviteter under ett operationsförfarande på centraloperationsavdelningen. Utifrån dessa togs lösningar fram för att förbättra de största problemområdena. Under tre arbetsiterationer analyserades och förbättrades konceptet. Det slutliga konceptet var en lösning för att förbättra kommunikationen mellan anestesiavdelningen och uppvakningsavdelningen. Genom att delautomatisera kommunikationen med hjälp av IT- systemet för operationsplanering kan UVA-koordinatorn göra en preliminär platstilldelning proaktivt och på så sätt undvika onödig telefonkommunikation i patientkristiska lägen. Denna visas sedan för anestesiavdelningen i operationsplaneringsprogrammet Orbit samt på en slavskärm vid ingången till uppvakningsavdelningen. Studien visade på positiva praktiska resultat för kombinationen av Lean och tjänstedesign. Den användarcentrerade utvecklingsmodellen skapade en stark förankring hos personalen av förändringsarbetet med Leanprocesser. Vidare sågs styrkor med tjänstedesign i att identifiera och tydliggöra kundvärde. En potentiell svårighet som diskuteras är huruvida det användarcentrerade arbetssättet passar för andra implementationsnivåer. Studien erbjuder inte en färdig verktygslåda för kombinationen av Lean och tjänstedesign men väl praktiska exempel som kan vara en grund för vidare studier.<br>In healthcare today there is a constant struggle with inefficient work processes and tight monetary assets to meet the challenges that come with an aging population and the demands it puts on the health care system. In response to these problems, this thesis focused on improving working processes at a large hospital, in Stockholm Sweden, and solving the problems to achieve a higher time and cost efficiency while maintaining a high level of patient safety. Non-value adding activities during a surgical procedure at the central surgical department were identified after observation and interviews by combining Lean and service design methodology. Design solutions based on these activities were developed to improve the most problematic areas. During three work iterations the concepts was analyzed and improved. The final concept was a solution to improve communication between the department of anesthesia and recovery section. By implementing semi-automated communication in the IT system for operation planning the recovery room coordinator can do a preliminary bed allocation proactively, thus avoiding unnecessary telephone communication in care intensive situations. The bed allocation information is then displayed for the anesthesia department in the operation planning program Orbit and on a screen at the entrance to the recovery section. The study indicated positive results of the combination of Lean and service design. The usercentered development method created a strong support for the change towards Lean processes amongst the employees. The service design methodology proved useful in identifying and clarifying customer value. A potential weakness in adapting the user-centered method to other levels of Lean implementation was discussed in the study. The study does not provide a plug and play toolkit for the combination of Lean and service design. It rather provides a practical example for future studies on the subject.

Full textAbstract:
Trust is an intrinsic component of any loyal “consumer friendship” between customers and service providers, and is a by-product of shared understanding. Nowhere is the notion of trust more relevant than in technical service—such as professional legal practice, architecture, medical care and auto repair—where the primary commodities exchanged are specialized knowledge, equipment and skills. A common challenge in dialogue between expert providers and novice customers in this context is meaningful sharing of technical information. A successful exchange requires care in representation, language, attitude, delivery and timing. Furthermore, with communication breakdowns, trust falters, and business relationships run the risk of falling apart.
Rather than relying on simple transactional exchanges of information in service, a customer’s journey could be enriched by framing service touchpoints as individual opportunities for learning. Learning activities occur in everyday life via interactions with society, artifacts or programs, and often involve the pursuit of knowledge or skills without the structure of a formal curriculum. This study explores how learning might function as a channel for strengthening multi-faceted trust relations in service through integration into programs and artifacts.
In this project, an auto repair shop was investigated as a case study in technical service, given its long inglorious history of customer mistrust. Through exploration in the context of a local mechanic shop, prototypes for experiential and transformative service learning were implemented, tested, and re-shaped into a four-part framework designed to improve technical communications

Anycast in next generation Internet Protocol is a hot topic in the research of computer networks. It has promising potentials and also many challenges, such as architecture, routing, Quality-of-Service, anycast in ad hoc networks, application-layer anycast, etc. In this thesis, we tackle some important topics among them. The thesis at first presents an introduction about anycast, followed by the related work. Then, as our major contributions, a number of challenging issues are addressed in the following chapters. We tackled the anycast routing problem by proposing a requirement based probing algorithm at application layer for anycast routing. Compared with the existing periodical based probing routing algorithm, the proposed routing algorithm improves the performance in terms of delay. We addressed the reliable service problem by the design of a twin server model for the anycast servers, providing a transparent and reliable service for all anycast queries. We addressed the load balance problem of anycast servers by proposing new job deviation strategies, to provide a similar Quality-of-Service to all clients of anycast servers. We applied the mesh routing methodology in the anycast routing in ad hoc networking environment, which provides a reliable routing service and uses much less network resources. We combined the anycast protocol and the multicast protocol to provide a bidirectional service, and applied the service to Web-based database applications, achieving a better query efficiency and data synchronization. Finally, we proposed a new Internet based service, minicast, as the combination of the anycast and multicast protocols. Such a service has potential applications in information retrieval, parallel computing, cache queries, etc. We show that the minicast service consumes less network resources while providing the same services. The last chapter of the thesis presents the conclusions and discusses the future work.

Full textAbstract:
Healthcare Informatics suffers from the lack of information exchange among domain partners. Allowing cooperation among distributed and heterogeneous applications is a major
need of current healthcare information systems. Beyond the communication and integration problems, medical information itself is by nature complex, combined with data and knowledge. The increasing number of standards and representation of the same data in different structures using these standards constitute another problem in the domain.
Platform and implementation independency makes Web service technology the natural way to solve the interoperability problems in the healthcare domain. Standardizing the access to data through WSDL and SOAP rather than standardizing the electronic health record will help to overcome the integration problems among different standards in medical information systems. However, introducing Web services to the healthcare systems will not suffice to solve the problems in the domain unless the semantics of the services are exploited.
This thesis aims to show that by generating web services and classifying these services through their functionalities, it is possible to achieve the interoperability among healthcare
institutes, such as hospitals. The designed system is based on Artemis P2P Framework, and the annotation of the system is realized in the same framework.

The recorded music industry was focused on understanding the dynamics of transitions from one generation of use to another. The recorded music industry was selected to study as it is one of the most dynamic and rapidly changing industries. Results of the most recent transition in the industry are deeply investigated. Utilizing numerical computing techniques, and mathematical models inspired by ecology sciences, a software package was created to analyze technology transitions. The software package was used to analyze the music industry. Accuracy of the technique was demonstrated and the model parameters were investigated and discussed. Effective strategies for the service transition are discussed. Limitations and characteristics of the transition are further investigated. Both new and existing firms from other industries who adapted well into such transitions are examined with the purpose of understanding critical points in their strategies that allowed them to execute such transitions successfully. Architectures of modern systems that reflect on the transition, such as product as a service are discussed. A few examples from the industry in which some of the critical components are transitioning to service model that resembles the ones in the music industry are given.<br>by Erdem Yilmaz.<br>S.M. in Engineering and Management

Findings reveal that a formal design strategy is the key to success. This thesis presents the development and validation of a framework for the design of personalized gamification services. This framework, called FRAGGLE (FRamework for AGile Gamification of personalized Learning Experiences), is based on the use of agile methodologies to obtain a fast design that is ready for testing and reproduction. It is aimed at applying different techniques, all the way down to the lowest levels of abstraction, through a guided, step-by-step process, including a design validation process of intrinsic motivation (SPARC). This approach was tested and assessed in two courses on an e-learning-based bachelor's degree in computer science, its goals being to encourage learners completing non-graded training activities, and to increase their sense of kinship and interest in the class group. The first case revealed a moderately positive assessment of the designed experience and student engagement in a "one-size-fits-all" proposal; meanwhile, the second case of study allowed assessment of which design elements had a greater impact on student engagement. Results from a further case of study also revealed that personalization worked better regarding students' behavioural and emotional engagement than previous generic approaches. Finally, the framework was also applied in a real healthcare environment through Preventive Neuro Health, a gamified, crowdsourcing-inspired tool developed for cognitive impairment prevention in healthy older adults. Aiming to motivate its regular use among these adults, it enabled a high degree of personalization both from clinical and engagement perspectives.

In the fast moving word of sofware engineering many are trying to get their piece of the pot of gold. To do that the engineering process needs to be as cost efficient as possible.Since time is money smartly designed systems make full use of already implemented sofware to save time and money with new development. The usage of services have become a well used strategy for the re-usage of software within as well as between businesses. Loose coupling has long been an architectural strategy for achieving modifiability. The loose coupling between services within a system has lately also been a subject of discussion, since there may be several advatages of using the principles regarding loose coupling and high cohesion within and between services. This document will examine the possible benefits as well as concern of decoupling already tightly coupled services. As well as discovering patterns and anti-patterns regarding coupling and services using Visma Spcs as a case study.

Full textAbstract:
There are unique challenges and opportunities related to the integration of electric vehicles into the future power grid, especially the modern distribution grid since electric vehicle (EV) charging facilities and fast-charging stations are usually tied to low-voltage and medium-voltage power networks. The grid-connected EVs, if properly controlled, can operate as distributed energy storage and provide various ancillary services, such as peak shaving, fast-response reserve capacity, frequency regulation, voltage control and reactive supports.
The purpose of this thesis is to integrate EVs to the power grid and provides suitable ancillary services to improve the grid reliability and stability. The larger future penetration of EVs and renewable energies is also taken into account to develop the vehicle-to-grid (V2G) control scheme with the constraints of EV charging and communication infrastructures. The main contents include: V2G mathematical model and system configuration; impact evaluation of EV integration and the V2G control framework; energy scheduling of EVs integration; V2G dynamic regulation services; control method of EV aggregator for dispatching a fleet of EVs; and the evaluation of V2G control scheme and hardware-in-the-loop experimental system design.
In the thesis, the impact of EV charging demand on the conventional distribution grid is firstly estimated to reveal the negative effects of the arbitrary EV charging and the necessity to control the EV charging process. The potential benefits EVs can bring into the power grid support are discussed and a V2G control framework is proposed to perform the V2G optimization and various regulation services. The current power electronics applied EV charging facilities and communication network are integrated into the V2G operation in the future distribution grid with microgrid and smaller installation of renewable generation units.
Next, mathematical model of V2G power control is formulated. Two optimization methods are proposed to schedule the EV charging and discharging energy to minimize the power losses and the operating cost while satisfying the mobility needs and the power system limitations. Subsequently, the dynamic regulation of V2G power is investigated to unleash the potential of EVs to provide multiple ancillary services simultaneously. In addition to V2G optimal energy scheduling, EVs can also be employed for dynamic power regulation which requires the fast response to the instantaneous imbalance between the power supply and demand. V2G power is controlled to mitigate the power fluctuation caused by the intermittent wind energy resources, and thus stabilize the system frequency and voltage.
Finally, an EV-centric hybrid energy storage system is proposed, which combines the merits of V2G operation and superconducting magnetic energy storage (SMES) to enhance the power quality and system frequency stability.

Full textAbstract:
WebRTC est une technologie récente de communication qui permet d’établir des échanges multimédia conversationnels directement entre navigateurs. Nous nous intéressons dans cette thèse à des locuteurs dans un Smart Space (SS) défini comme un environnement centré-utilisateur instrumenté par unensemble de capteurs et d’actionneurs connectés. Nous analysons les capacités nécessaires pour permettre à un participant d’une session WebRTC d’impliquer dans cette même session, les flux induits par les objets connectés appartenant au SS d’un utilisateur quelconque de la session. Cette approche recèle un gisement de nombreux nouveaux usages. Nous limitons notre analyse à ceux concernant l’exercice distant d’une expertise et d’un savoir-faire. Techniquement, il s’agit d’articuler de façon contrôlée WebRTC et IoT/WoT. Nous procédons à une extension de WebRTC par WoT pour fournir à tout utilisateur d’une session WebRTC, un accès aux objets connectés du SS de tout autre participant à la session, en mettant l’accent sur la sécurisation de cet accès ainsi que sur sa conformité aux exigences de respect de la vie privée (RGPD) de l’utilisateur concerné. Le positionnement de notre approche dans le contexte des services de communication opérant dans les villes connectées, impose la prise en compte de SSs multiples et variés induisant chacun ses propres politiques de routage et de sécurité. Pour répondre à nos objectifs, il devient nécessaire au cours d’une session WebRTC, d’identifier, sélectionner, déployer et appliquer les règles de routage et de sécurité de façon à garantir un accès rapide et sécurisé aux différents SSs concernés et distribués sur tout le réseau. Nous développons une architecture originale répondant à ces besoins et intégrant un contrôleur SDN du fait de l’étroite imbrication entre les problématiques de routage et de sécurité. Un prototype illustrant notre approche a été mis en oeuvre et testé afin d’évaluer la performance et la sécurité du système. Nous illustrons finalement notre approche dans le domaine de la santé en démontrant son apport pour gérer une infrastructure de grande taille telle qu’un hôpital<br>The richness and the versatility of WebRTC, a new peer-to-peer, real-time and browser based communication technology, allowed the imagination of new and innovative services. In this thesis, we analyzed the capabilities required to allow a participant in a WebRTC session to access the smart Things belonging to his own environment as well as those of any other participant in the same session. The access to such environment, which we call “SmartSpace (SS)”, can be either passive, for example by monitoring the contextual information provided by the sensors, or active by requesting the execution of commands by the actuators, or a mixture of both. This approach deserves attention because it allows solving in an original way various issues such as allowing experts to remotely exercise and provide their expertise and/or knowing how. From a technical point of view the issue is not trivial because it requires a smooth and mastered articulation between two different technologies: WebRTC and the Internet of Things (IoT) /Web of Things (WoT). Hence, the first part of the problem studied in this thesis, consists in analyzing the possibilities of extending WebRTC capabilities with theWoT. So as to provide a secure and privacy-respectful access to the various smart objects located in the immediate environment of a participant to any otherend-user involved in the same ongoing WebRTC session. This approach is then illustrated in the ehealth domain and tested in a real smart home (a typical example of a smart space). Moreover,positioning our approach in the context of communication services operating in smart cities requires the ability to support a multiplicity of SSs,each with its own network and security policy. Hence,in order to allow a participant to access one of his own SSs or one of another participant (through a delegation of access process), it becomes necessary to dynamically identify, select, deploy, and enforce the SS’s specific routing and security rules, so as to have an effective, fast and secure access. Therefore, the second part of the problem studied in this Ph.D.consists in defining an efficient management of the routing and security issues regarding the possibility of having multiple SSs distributed over the entire network

These service strategies have the potential to improve bus performance as well as service quality. However, the implementation of these service strategies may lead to an increase in access times and waiting times for some passengers compared with an all-local service configuration. Therefore, agencies face trade-offs between reducing bus running times and reducing total passenger travel time when designing a service plan for these overlapping strategies. This thesis focuses on developing a methodology for the design and evaluation of service configurations for limited-stop (or BRT) services overlapping with local services. The developed methodology proposes evaluating limited-stop (or BRT) service configurations by six measures of effectiveness including: market share (passengers always waiting for the limited-stop service, passengers always waiting for the local service, and passengers always taking the first bus that comes), demand split, average passengers per trip, service running times, change in average passenger travel time, and change in corridor ridership. A model was developed to obtain the proposed measures of effectiveness for user-defined service configurations. This model is an improvement to that developed by Schwarcz (2004) since it allows forecasting ridership changes due to the implementation of these service configurations, assigns demand using a probabilistic choice approach, and models running time changes when BRT elements are introduced. The methodology developed to evaluate limited-stop and BRT services was applied to two CTA case studies: Chicago Avenue and 7 9th Street. Different scenarios of limited-stop and BRT services overlapped with local services were tested, examining variations in stop spacing, service frequencies, and different BRT elements such as: right-of-way segregation, enhanced boarding, and Transit Signal Priority. The results of the analysis shows the critical importance of the enforcement of preferential rights-of-way (in BRT scenarios) to achieve high corridor performance and that frequency shares (the ratio of limit-stop services buses to local buses serving the corridor in an hour) should be greater than 50% for limited-stop services and greater than or equal to 60% for BRT services. Additionally, total demand, concentration of origins and destinations, average trip length, and trip length distribution were shown to be critical to the effectiveness of limited-stop and BRT services.<br>by Harvey Scorcia.<br>M.C.P.<br>S.M.in Transportation

Full textAbstract:
The work presented in this thesis is based on the assumption that modern computer technologies are already potentially pervasive: CPUs are embedded in any sort of device; RAM and storage memory of a modern PDA is comparable to those of a ten years ago Unix workstation; Wi-Fi, GPRS, UMTS are leveraging the development of the wireless Internet. Nevertheless, computing is not pervasive because we do not have a clear conceptual model of the pervasive computer and we have not tools, methodologies, and middleware to write and to seamlessly deliver at once services over a multitude of heterogeneous devices and different delivery contexts. Our thesis addresses these issues starting from the analysis of forces in a pervasive computing environment: user mobility, user profile, user position, and device profile. The conceptual model, or metaphor, we use to drive our work is to consider the environment as surrounded by a multitude of services and objects and devices as the communicating gates between the real world and the virtual dimension of pervasive computing around us. Our thesis is thus built upon three main “pillars”. The first pillar is a domain-object-driven methodology which allows developer to abstract from low level details of the final delivery platform, and provides the user with the ability to access services in a multi-channel way. The rationale is that domain objects are self-contained pieces of software able to represent data and to compute functions and procedures. Our approach fills the gap between users and domain objects building an appropriate user interface which is both adapted to the domain object and to the end user device. As example, we present how to design, implement and deliver an electronic mail application over various platforms. The second pillar of this thesis analyzes in more details the forces that make direct object manipulation inadequate in a pervasive context. These forces are the user profile, the device profile, the context of use, and the combinatorial explosion of domain objects. From the analysis of the electronic mail application presented as example, we notice that according to the end user device, or according to particular circumstances during the access to the service (for instance if the user access the service by the interactive TV while he is having his breakfast) some functionalities are not compulsory and do not fit an adequate task sequence. So we decided to make task models explicit in the design of a service and to integrate the capability to automatically generate user interfaces for domain objects with the formal definition of task models adapted to the final delivery context. Finally, the third pillar of our thesis is about the lifecycle of services in a pervasive computing environment. Our solutions are based upon an existing framework, the Jini connection technology, and enrich this framework with new services and architectures for the deployment and discovery of services, for the user session management, and for the management of offline agents.

Potti, Pavan Kumar. "On the Design of Web Services: SOAP vs. REST." UNF Digital Commons, 2011. http://digitalcommons.unf.edu/etd/138.
Full textAbstract:
The purpose of this thesis is to compare the performance characteristics of Simple Object Access Protocol (SOAP) and Representational State Transfer (REST), which are methods of supporting interactions among Web services. They differ in both context and usage; SOAP is a protocol while REST is architecture. SOAP is a well-developed protocol used in the Web industry and is standardized by the World Wide Web Consortium (W3C). REST is the outcome of Dr. Roy Thomas Fielding’s 2000 PhD dissertation, “Architectural Styles and the Design of Network-Based Software Architecture.” REST is gaining in popularity due to its simplicity, scalability, and architectural dependence on the World Wide Web. Major software companies, such as Google and Amazon, among others, have started using REST. The main difference between the two methods is SOAP is a tightly coupled system, whereas REST is a loosely coupled system; both have advantages and disadvantages.
We built SOAP and REST based Web services that performed the GET, POST, PUT, and DELETE functions on a database. We utilized response time and throughput metrics to compare the performance of these Web services. In comparing the two technologies, we found REST was considerably faster, compared to SOAP, because the response times of REST were better than those of SOAP. As an ancillary outcome, we found building Web services using SOAP was easier, due to considerable tool support, whereas developing Web services using REST was time consuming, as it provides no tool support.

Full textAbstract:
Ubiquitous wireless communications, information mobility and location-based information services have created a new layer of urban experience, an information layer. The information services that deliver this layer to the urban actor (particularly pedestrians) will soon be ubiquitous and using those services a normal and integral part of the urban experience; more than an optional and utilitarian adjunct to it. The urban setting for these services prompts the question as to whether urban designers should be playing a role in their design and development; a role that seems conspicuously absent from current services. This thesis explores mechanisms which might facilitate a greater role for urban design by seeking ways in which the information architecture that underpins these information services might better reflect the qualities and complexities of urban space that urban designers recognise and value. The work of a range of prominent urban design thinkers is reviewed for ideas, constructs and elements that can be incorporated into an enriched information architecture which could in turn deliver information services that do justice to the depth and complexity of the urban environment. Technologies and standards associated with the ‘semantic web’ are identified as those which might best accommodate an appropriate information architecture; in particular, the ability to reflect the network characteristics of urban space viewed as a multi-dimensional graph of interconnected nodes. This view of urban space is contrasted with the relatively flattened view offered by global geo-spatial capability. An information model is built (only one of many possibilities) and validated using a limited test area in central Sydney. Practical and institutional issues which may impinge on the realisation and deployment of such a model in a real world setting are briefly considered in an appendix.

This design thesis is part of CATEA's RERC workplace accommodations grant, and it adopts a human centered design methodology to research, develop, test and evaluate designs of behind-the-counter workspaces that maximize independence and participation of employees and increase their employment possibilities. Preliminary research shows that current designs of behind-the-counter workspaces do not accommodate needs of intended employees including the seated and standing users. According to the research, factors like task design and lack of ease of use have contributed to job loss and reduced employment. Through participatory research techniques and ergonomic studies, this project identified accessibility and usability needs and outlined basic and extended design guidelines for behind-the-counter workstations that would address these needs. Results from observational research, usability studies and user interviews were analysed to create design specifications for a range of workstations. The resulting workstation designs incorporate universal design guidelines and aim to expand employment opportunities for people with disabilities and older adults.
