Namibia, southern Africa, suffers from an energy shortage and is therefore facing severalchallenging problems. The use of firewood as fuel for cooking is common in the whole countryand has negative consequences for health and the environment. This work have focused ondeveloping a solar baking oven, calledSunbaker, adapted for Namibian families needs forbaking. The development was based on classic solar cooking limitations, specific needs forNamibia and to have a feasible manufacturability.The project started with a theoretical study in Sweden where different solar cookers, informationregarding Namibia, technical aspects and end user aspects were studied. To assess the need for asolar baking oven aMinor Field Study took place in Namibia during eight weeks in July toSeptember 2009 and resulted in a product design specification.

This work derives from the question ?What is a beautiful road??. The question is being discussed in interviews with two employees at the Swedish National Road Administration and two former members of the ?Council of environment and beauty? at the Swedish National Road Administration. The interviews are summarized in my own discussion about the concept of ?Beautiful roads?.

This bachelor thesis is about an ultrasonic sensor, implemented in a bubble chamber in Artis. The sensor consists of the piezoelectric sensor and an electronic control circuit. The control circuit consists of a programmable microprocessor, PIC18F2420 and a circuit, which sends the excitation signal to the piezoelectric sensor, and later receives the echo. This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.

This report describes the initial work intended for updating the car sharing service Roadmate. Roadmate is one of the services received by the car rental company Hertz First Rent a Car.

Publit är ett litet företag med stora ambitioner. Efter bara fyra år på marknaden servar man nu enmajoritet av de största svenska förlagen (och en lång rad mikroförlag) med e-boktjänster ochbehovstryck.Användaren får tillgång till Publits tjänster via en webbapplikation som i stora drag har tre vyer;analys, ekonomi och katalog. Den sistnämnda rymmer ett förlags utgivning av fysiska ochelektroniska böcker och låter användaren göra allt från att skanna en fysisk bok eller konvertera enPDF till e-bok, till att publicera sina böcker i en lång rad kanaler och välja priser ochaffärsmodeller.Publits katalogvy har en rad brister. Det har varit vår uppgift att fullt ut förstå och kartlägga dessa.Den processen har bedrivits i form av iterativt skissande varvat med design-kritik-möten.Resultatet kan ses i två perspektiv. För vår egen del består det av ett mycket stort antal skisser somillustrerar vår process.

This report evaluates various methods that can be used to position a smartphone running the Android platform, without the use of any special hardware or infrastructure and in conditions where GPS is unavailable or unreliable; such as indoors. Furthermore, it covers the implementation of such a system with the use of a deterministic fingerprinting method that is reasonably device independent, a method which involves measuring a series of reference points, called fingerprints, in an area and using those to locate the user.The project was carried on behalf of Sigma, a Swedish software consulting company..

Tolking och tillgodogörande av datastrukturer, organiserad information ochprogramkodsfiler förekommer frekvent i arbete med mjukvaruutveckling. Dennainformation är lagrad i textbaserad form och dess förståelse kräver stornoggrannhet och tidsinvestering från utvecklarens sida. I syfte att försöka förenklaprocessen beskriver detta examensarbete utvecklingen av en prototyp till ettverktygsprogram, vilket automatiserar tolkning av XML-data och källkodsfiler förprogrammeringsspråken C och C++. Programmet skapar och presenterar sedanen visuell graf av den undersökta strukturen. Algoritmen klarar av att presenteragodtyckligt stora XML-filer samt ett begränsat antal samtidigt inlästakällkodsfiler.

Many companies today are investing in various computer-based tools to support their planning, decision making or communication processes. However, end users are often reluctant to accept the available information systems, which mean that these investments are extremely risky. Understanding why users choose to accept or reject an information system has proved to be one of the most challenging problems in this research area. Previous studies have focused on users' beliefs and attitudes regarding use intentions, but the results have, however, been both mixed and incomplete. In this study, I have used the Swedish youth? s use intention of mobile banking and a quantitative study was performed based on five different hypotheses derived from previous studies.

This thesis was performed at SverigeGrepen AB. SverigeGrepen is a company that hasone product on the market; a manure fork that is designed to be used for mucking inshavings or peat. The aim of this thesis was to develop a new manure fork that isadapted to be used in straw.The development started with a pilot study where experience of mucking wascollected to be able to understand what and why certain characteristics are importantfor the function and use of the manure fork.A basic concept was developed where the main function was fulfilled, which meantthat a separation between dung and straw could be performed in a way that wasbeneficial for the user.The work resulted in four concepts of how a manure fork could be used in the strawthat can be designed and constructed. The conclusion that the work gave was that allconcepts met the main requirements required by a manure fork to use in straw.However, concept four provides a good visual impression, while its benefits areassumed to be important qualities..

Bitcoin is a digital currency that is used by people all around the world. The goal of this paper is to give an idea about how much trust there is in bitcoin among its users. This paper has used an online survey aimed at bitcoinusers and a content analysis to collect data about this trust.The conclusions show that there seems to be some trust in bitcoin as a technology and this is based on that the users have a good understanding about how bitcoin works. They also share their knowledge about bitcoin to people around them. The trust between people in the bitcoin network on the contrary doesn?t seem as high because certain technological properties hurt this trust.

Immersion is a construct that measures how deeply engrossed a user is with any mediated situation. In the field of game design, immersion is a significant aspect of what makes a game enticing, and as such it is of pivotal importance to create and maintain it to keep the player's mind off the real world while inside the confines of a game framework. According to the GameFlow theory, it is one of seven key tenets of evaluating and implementing a successful game design. Yet, certain multiplayer online games are designed in a fashion that in some cases seem to break immersion, where the player is frequently put out of action, sometimes for minutes on end. In this study, using online questionnaires, we discover that players, despite claims otherwise, seem to be in several ways affected negatively by this breaking of immersion.
