In dieser Forschungsarbeit geht es um die königliche Modellkammer der Universität Göttingen. Diese historische Lehrsammlung hat bis heute zahlreiche Spuren hinterlassen. Trotz Professionalisierung der Sammlungsarbeit und der ständigen Einbindung der Modelle ins universitäre Curriculum der philosophischen Fakultät, insbesondere der angewandten Mathematik, existierten fast zu keiner Zeit angemessene Nutzungsbedingungen. In den 1880er Jahren wurde die Sammlung aufgelöst, wobei der Prozess der Auflösung in den Akten detailliert dokumentiert ist. Darüber hinaus sind bis heute 24 Modelle der ehemaligen Sammlung erhalten. Aufbau und Umfang der Göttinger Modellkammer korrespondieren mit den universalen Modellsammlungen der Zeit, deren Ursprung in höfischen, städtischen und bürgerlichen Kunstkammern zu finden ist. Genutzt wurden Modelle und Modellsammlungen zum Beispiel zu Zwecken der Machtdemonstration, zum Planen und Entwerfen, als Muster, zum Spielen und Experimentieren, aber vor allem in Lehre und Bildung. Neben der Erforschung der alltäglichen Praxis der historischen Sammlungsarbeit steht die Untersuchung der curricularen Nutzung mit der königlichen Modellkammer im Fokus der Arbeit. Dazu wurden einige der heute noch vorhandenen historischen Modelle der Sammlung eingehend untersucht, analysiert, in Bezug auf ihre historische curriculare Praxis befragt und individuell kontextualisiert. Besonders durch die Begegnung mit den Objekten ergaben sich vielfältige Fragestellungen. Letztendlich erzwingen die zahlreichen Informationslücken, die sich bei der Erforschung des alltäglichen Umgangs mit der historischen Lehrsammlung durch Schrifttum und Objekte zwangsläufig auftun, ein überwiegend heuristisches Vorgehen. / This research paper is about the königliche Modellkammer (Royal Model Chamber) of the University of Göttingen. This historical teaching collection has left numerous traces to this day. Despite the professionalisation of the collection's work and the constant integration of the models into the university curriculum of the Faculty of Philosophy, especially applied mathematics, appropriate conditions of use existed almost at no time. In the 1880s, the collection was dissolved, and the process of dissolution is documented in detail in the files. In addition, 24 models from the former collection have been preserved until now. The structure and scope of the Göttingen Model Chamber correspond to the universal model collections of the time, whose origins can be found in courtly, municipal and bourgeois art chambers. Models and model collections for example were used for purposes of demonstrating power, for planning and designing, as patterns, for playing and experimenting, but above all in teaching and education. In addition to researching the everyday practice of historical collection work, the focus is on investigating curricular use with the royal model chamber. To this end, some of the historical models of the collection that still exist today were examined in detail, analysed, questioned in relation to their historical curricular practice and individually contextualised. Especially through the encounter with the objects, a variety of questions emerged. Ultimately, the numerous gaps in information that inevitably open up when researching the everyday use of the historical teaching collection through written material and objects force a predominantly heuristic approach.

The increasing trends towards customization which has also been emphasized as a competitive advantage have resulted in engineering-to-order (ETO) companies having a leading role in many industries. However, in parallel with this digital information and technological advancement is rising, and companies are aiming to improve their processes to consequently reach greater success in their operations. Recent research has discussed Industry 4.0 and improved production planning methods in the manufacturing industry. Thus, manufacturing companies are striving to increase their efficiency levels and readily available data has been one of the most important and common denominators for this transformation, in fact, considered a necessity to survive in the current highly competitive market. Despite this, data collection which is a crucial part remains unexplored by academia and especially in ETO but also production planning methodologies as well as tool considering that they have a complex production process and relies heavily on manual labor from skilled operators.  Thus, this thesis sets out to investigate and explore shopfloor data collection and production planning and control (PPC) in the ETO environment. The research approach used here was a case study at an electrical transformer manufacturing plant located in Sweden. However, this study has also considered benchmarking companies as well to achieve the result of this study. Data collection techniques used were interviews, observation, and an extensive literature review that has guided the realization of the aim and gave a base to the suggested improvement for the problems identified. The findings of this master thesis illustrated that there is a lack of detailed plans, detailed information, manual effort, and lack of IT development which negatively impacts the performance of PPC. Furthermore, this had a strong correlation with the still manual shopfloor data collection that many ETO companies rely on. Principles that can be employed to mitigate the effects are further discussed in detail throughout the thesis.

Data collection is one of the important components of public health systems. Decision makers, policy makers and health service providers need accurate and timely data in order to improve the quality of their services. The rapidly growing use of mobile technologies has increased pressure on the demand for mobile-based data collection solutions to bridge the information gaps in the health sector of the developing world. This study reviews existing health data collection systems and the available open source tools that can be used to improve these systems. We further propose a prototype using open source data collection frameworks to test their feasibility in improving the health data collection in the developing world context. We focused on the statistical health data, which are reported to secondary health facilities from primary health facilities. The proposed prototype offers ways of collecting health data through mobile phones and visualizes the collected data in a web application. Finally, we conducted a qualitative study to assess challenges in remote health data collection and evaluate usability and functionality of the proposed prototype. The evaluation of the prototype seems to show the feasibility of mobile technologies, particularly open source technologies, in improving the health data collection and reporting systems for the developing world.

Vi lever i ett datadrivet samhälle där individer och tjänster ständigt loggar, spårar och behandlar information om sina egna eller andras beteenden. Informationsteknologi för datadriven beteendeförändring är centralt inom områdena Personal Informatics, en klass verktyg som hjälper individer att samla och undersöka personligt relevant information i självreflekterande syfte, samt Persuasive Design, som handlar om att känna till de bakomliggande orsakerna om vad som motiverar användare att agera och designa för att uppnå detta. Trots denna gemensamma huvudfokus bedrivs forskning kring områdena delvis separat. På grund av det stora överlappet mellan de två områdena behövs en översikt över vad som anses särskilt viktigt inom både Personal Informatics och Persuasive Design. Därför har vi genomfört en litteraturstudie för att på ett samlat sätt presentera den forskning som finns samt vilka generella lärdomar som belyses av forskare inom området. Resultatet visar mönster och skillnader i den gemensamma basen av litteratur, vilket möjliggör för djupare insikt i området. Vi diskuterar dessa mönster och möjligheter för vidare forskning av de resultat vi fått in samt vilka aspekter som anses särskilt viktiga. / We live in a world where products and services constantly try to affect our behavior. Data driven information technology for achieving behavior change is a central concept in Personal Informatics, a class of tools for assisting individuals in collecting and reviewing personally relevant information in self-reflective purposes, as well as Persuasive Design, which concerns the underlying factors behind motivating users into action and designing to achieve this. Despite these similarities in focus, these areas are partly researched as different fields. Because of the common grounds between the research areas, we believe an overview of the research literature concerning both Personal Informatics and Persuasive Design is important. For this reason we have performed a literature study so that we, in an organized manner, can present the aspects which are studied as well as insights highlighted by scientists in the area. We discuss patterns and possibilities for future research by the results we have collected as well as which aspects are considered especially important.

Rapid urbanization brings an increasing pressure on current waste collection and transportation methods to cope with ever-increasing waste streams in urban environments. Pneumatic Waste Conveyance Systems or PWCS is often seen as an alternative for replacing open-handling of waste in narrow and congested town environments.  This research intends to find out when, where and why such systems would be implemented, and the entirety of stationary PWCS implementation and usage is being investigated, from government, experts, developers, suppliers, system owners/ operators, users to the general public. The findings are reported and analyzed using a variety of methods including but not limiting to a case study for public- housing retrofit-projects in Singapore.  Results affirm that PWCS is useful for waste collection in densely populated urban areas while offering both advantages and disadvantages as noted in this study. That which is remarkable is however spotting more concerns than opportunities and some of these concerns are highlighted and discussed in this paper. Although some parts of the study proved to be challenging and thus inconclusive, strong consensus are found regarding the need for long-term planning and strategic conception to reap the intended benefits that PWCS can offer. / Den fortlöpande urbaniseringen bidrar till att dagens metoder för hämtning och transport av avfallsmängder blir allt mer utmanande och svårhanterlig i förorter och stadsbebyggelse. Sopsugssystem betraktas därför allmänt som en alternativ lösning i urbana miljöer eftersom tekniken tillåter att byta ut rådande öppen sophantering i skrymmande och trafikerade stadsmiljöer.  Denna forskningsinsats avser att få bättre visshet om när, var samt varför sopsugssystem bör användas utifrån ett vidvinkelsperspektiv som försöker belysa och klarlägga helheten kring implementeringen och användandet av dylika system. För att uppnå detta syfte har statliga myndigheter, experter, bostadsbyggare, entreprenörer, ägare/ operatörer för system samt användarna kontaktats och hörsammats. De viktigaste inläggen har därefter rapporterats och analyserats med underlag av ett flertal metodologier som även innefattat en fallstudie för allmännyttiga fastigheter där sopsug installeras i en befintlig stadsarkitektur i Singapore.  Resultaten verifierar att sopsugssystem är användbara för avfallshantering och transport i tätbebyggda stadsområden samt att systemen offererar både fördelar och nackdelar. Det som är anmärkningsvärt är att fler aktsamhetsområden än möjligheter har upptäckts för vilka ett urval av dessa har tagits upp samt diskuterats mer ingående i denna rapport. Trots att delar av studien inbjöd till diverse utmaningar, vilket har föranlett till att resultatbilden inte kan ge klara och tydliga svar, så fanns fortfarande stor samstämmighet beträffande behovet av långsiktig planering och strategisk insiktsfullhet för att säkerställa de åtråvärda nyttor som sopsugssystem i stort kan erbjuda.
