Dagens samhälle är i behov och strävar efter att få ner energianvändningen. Inte minsti byggsektorn där nyare teknik och smarta innovationer gör att vi kan sänka vårenergiförbrukning och då även få ner våra energikostnader. Ett sätt att reducera dessabåda faktorer är att byta ut gamla ventilationslösningar mot nya mer energieffektivasystem. Att välja en viss typ ventilationssystem är däremot inte alltid ett enkelt beslutdå det finns ett flertal olika principer av system man kan utgå ifrån för att ventilera enlokal och skapa ett bra inneklimat. De enklaste ventilationssystemen ger ett konstantluftflöde medans man med mer avancerade system kan använda sig av varierandeluftflöden för att förse en lokal med frisk luft utefter det behov som finns.Denna rapport har i sin helhet tittat på de förutsättningar som finns då man utformarett ventilationssystem för en förskola.

Företag behöver öka farten på införandet av mobila system för att kunna hänga med i den hårt ökande konkurrensen och globaliseringen som sker. För att satsa pengar i ny teknik är det dock viktigt att se tydliga affärsfördelar med investeringen. Här saknas kunskaper och medvetenhet hos företag om möjlig effektivisering som mobila system kan medföra i verksamheter. Syftet med undersökningen är att utvärdera Pågens mobila system utifrån ett organisatoriskt effektivitetsperspektiv. En fallstudie på Pågen AB har genomförts där effekterna av införandet av deras mobila orderhanteringssystem utvärderas.

The purpose of this study is to research into the role of the citizen and the educational system in Sweden throughout periods of time based on previous theoretic works, and also to deepen the understanding of students with special needs in Swedish education focusing on the primary school years. This shall be carried out by illustrating the different points of view and choices within the educational system that are at hand for students with concentration difficulties and social difficulties.I will analyze these points through a cultural and social perspective on contemporary society in order to contribute towards today?s discourse on the norm. The result of this empirical investigation presents a dilemma existing in the democratic educational system of today. Nationally and internationally, the educational system has been structured around a normative system containing both rights and duties that effect everyone working within it.

I den här rapporten undersöks Command Query Responsibility Segregation (CQRS),Event Sourcing och Task Based User Interface (händelsebaserat gränssnitt) somtillsammans bildar en annorlunda arkitektorisk uppbyggnad av system. Tanken bakomarkitekturen är att kunna spåra vad, när och hur data förändras i ett system samtmöjlighet att återskapa tidigare tillstånd, jämfört med traditionella system som endastlagrar, hanterar och presenterar data i dess nuvarande tillstånd. Undersökningen hargjorts genom att ta fram en bokningsprototyp och resulterade i för ?och nackdelar,användningsområde och hur CQRS, Event Sourcing och händelsebaserat gränssnitt kanimplementeras tillsammans..

The aim of this Masters thesis is to investigate how trained social workers experience information in their daily work. The thesis focussed on three major questions: - What type of information and information sources are mostly used by the trained social workers? - What kind of information barriers are described by the participants? - How can the patterns of information seeking and information use be understood on the basis of the trained social workers professional and social context? Semi-structured interviews were carried out with trained social workers working with child welfare enquiries. My theoretical framework consists of user and context oriented theories about classifications of information, information barriers and models of information sources. My conclusions are that trained social workers working with risk assessment in child protection services, need to use different kinds of information in their daily work, such as problem information, domain information and problem-solving information.

The report aims to investigate how well a certain type of affordable embedded single board computer can hold up against today's more expensive computers in a computer system by doing various tests on a system with the specified requirements. The system has a Raspberry Pi as the single board computer which task is to control a camera based on coordinates obtained from a server as well as capture and stream a video signal on a network.The researches were conducted to check how much network traffic a single-chip computer sent in different video formats and how much CPU utilization was required. Studies were also made to ensure the accuracy of the camera control. The researches have been experimental, where several tests have been performed and analyzed.The results show that a sufficiently good accuracy can be obtained from the camera steering unit, in which two different servos have been investigated. When the video format MJPEG and H.264 are used, the single-chip computer is able to transmit a video signal up to 1280x720 at 15 fps.

Today there are many system development projects that break both budget and time plan. Often this depends on defects in the information systems that could have been prevented. The cost of test can in some cases be as high as 50 % of the projects total cost and it's at the same time an important part of development. Test as such has moved its focus from the software it self and its faults to a wider perspective on whole infrastructures of information systems where assure a good quality is important. Sogeti in the Netherlands have developed a test method called TMap (Test Management approach) that can be used for structured testing of information systems.

Students at Jönköping School of Engineering were given an assignment from Jönköping municipality, to evaluate their decision support system, QlikView. The students have also developed proposals for improvement with focus on usability.The Jönköpings municipality has currently got 11000 employees and consists of nine different administrations. The target group for QlikView is approximately 600 first-line managers.The intention of QlikView is that the users can get an overall picture of their business by having all information in just one system.The purpose of the thesis is to obtain a picture of what the users think about the system today and present relevant suggestions for improvement, which the Jönköping municipality can use when the introduction of the new version of QlikView takes place. The research questions that the study aims to answer are:? Has QlikView got a user friendly interface?? How can the interface be improved to become more user friendly?Theories that this work is based on is Jacob Nielsens ten usability principles and Ben Schneidermans eight golden rules.

This master thesis investigates the possibilities of using GPS-information from trains to create a model of a railway system, register the routes of the the trains and predict how the trains will travel in the railway system.The thesis work was done at Icomera AB which is a company that specializes in internet connected vehicle solutions.We describe how the GPS-information is sent from the trains in the form of samples and investigate limitations and possibilities with the available information. About three million samples from 83 SJ-trains were analysed and the samples were filtered with the intent of removing erroneous information. We here found that about 30 % of the samples from the trains were unreliable.A solution for how the samples from the trains can be used to create a model of the railway system traveled by the trains is presented. We use a large set of historical samples and use cluster nodes and Hermite curves to generate a graph that represent the railway system with stations, nodes and the railway itself. A fully automatic solution is not presented since it did not fit into the time frame of the thesis; instead we created a simple tool which can be used to manually finish the model of the railway system.Furthermore, we describe how the railway system and the samples from the train can be used to register the routes the trains travel.

Problemställning: Det existerar idag en betydande forskning som berör digitala system för kunskapsöverföring. Emellertid ser vi en tydlig brist i forskningen kring användandet av de olika systemen. Detta beror till stor del på problemet med att kunna mäta att en medarbetare verkligen använder systemet för kunskapsöverföring. Genom att studera kunskapsutbytet i organisationerna hade det varit möjligt att kartlägga de områden som påverkar användningen av digitala system för kunskapsöverföring. Frågeställning: Vilka faktorer påverkar användningen av digitala system för kunskapsöverföring? Syfte: Syftet är att skapa en modell som visar de faktorer som påverkar användningen av digitala system för kunskapsöverföring, samt att genomföra en första prövning av modellens giltighet genom en studie av tre företag.

Vid design av IT-system krävs en förhållning till de specifika egenskaper som finns i den miljösystemet är tänkt att användas. Även om användningen ser liknande ut krävs en detaljeradanalys av det specifika sammanhanget för att få en djupare förståelse för hur det verkligaanvändningsområdet ser ut. Det har visats sig uppkomma användbarhetsrelaterade problem vidförflyttning av ett system från en stationär miljö till en mobil miljö. Rapporten har undersöktvilka utmaningar som uppkommer när ett system flyttas från en mobil miljö till en annan snarlikmobil miljö och tar sin utgångspunkt i Ecodriving-lösningar för tunga fordon. En kvalitativundersökning genomfördes för att undersöka och identifiera de utmaningar som uppkom.Analyserat material låg till grund för framtagningen av en prototyp.
