Denna rapport omfattar ett 15 poängs (22,5 högskolepoäng) examensarbete vid Karlstads universitet. Arbetet har utförts på plats hos BAE Systems Bofors i Karlskoga. Företaget ville kunna styra en radiostyrd leksaksstridsvagn med en laserpekare. En kamera ansluten till en digital signalprocessor (DSP) skulle kunna detektera var en laserpunkt befinner sig och styra stridsvagnen mot den.Ett styrgränssnitt mellan DSP:n och leksaksstridsvagnen konstruerades och byggdes med hjälp av en programmerbar logisk krets. Leksaksstridsvagnens interna signalsystem analyserades.

VD:n för spelindustrins intresseorganisation (Interactive Digital Software Association) förutspår i den årliga State of the Industry rapporten för åren 2000 ? 2001, att spelindustrin snart kan nå 70 procent av världens hushåll, vilket gör spelmaskinen, näst intill, lika vanlig som videon. I denna dag börjar många spelutbildningar växa fram i hela landet, så som i Karlshamn, Visby och Kramfors. Trots denna tillväxt finns det nästan ingen akademisk forskning i ämnet speldesign. Detta gör att hjulet i många fall tvingas återuppfinnas om och om igen. I detta kandidatarbete är huvuddiskussionen hur man designar ett spel innehållande både spelfrihet och en färdig berättelse, vilket är en konflikt i sig. Vi försöker identifiera kärnan av ett spels design genom att samarbeta med både användare och designers av digital underhållning och sätta detta i relation till de studier av spel vi gjort.

During the development of microwave based sensors such as radar target seekers, input signals are needed to verify the performance of the system. Therefore, a channel board has been developed by previous thesis projects at Saab Bofors Dynamics. It uses a technique called Digital Radio Frequency Memory (DRFM). The purpose of this board is to sample and digitally store radio frequency signals in order to reconstruct them after a certain delay.The aim of this thesis project was to use the channel board named above to construct a portable instrument for generation of stimuli signals. This assignment has been divided into two tasks: firstly, to construct and put together the hardware components and secondly, to implement a graphical user interface for the instrument.

During spring 2012, six students at the Royal Institute of Technology in Stockholm carried out agroup project in the field of mechatronics as part of the thesis for the bachelor degree. The resultwas a robot with active balancing and the purpose of this report is to describe the development,manufacturing and problems that arose during the project. The finished robot has two wheelsmounted in line with each other, like a bicycle. Measurement data from an accelerometer and agyroscope are used together in a complementary filter for determining the angle from the verticalplane. For balancing, a PID controller was used to control the rotation of a reaction wheel, whenaccelerating causes a straightening torque.

Detta examensarbete handlar om huruvida aktiva kort kan användas som säkerhetshjälpmedel vid hantering av datoriserade patientjournaler inom sjukvården.Rapporten börjar med en beskrivning av informationssystemen och informations-säkerheten inom sjukvården. Därefter ges en beskrivning av aktiva kort, deras för- och nackdelar samt vilka säkerhetsfunktioner som kortet tillhandahåller.Fokuseringen ligger på om är det tekniskt möjligt för behörig personal att med hjälp av aktiva kort logga in på olika informationssystem och ge dem tillgång till den information som de behöver i patientjournalen och ändå hindra obehörig åtkomst. Gällande lagar och föreskrifter tas i beaktning samt hur aktiva kort kan användas vid digital signering av patientjournaler.Undersökningen har genomförts med hjälp av litteraturstudie. Först undersöktes vilka krav som bör uppfyllas när patientjournaler skall datoriseras. Därefter studerades vad som är tekniskt möjligt att utföra med aktiva kort.

This thesis aspires to construct a routing optimization method customized for Volvo Powerstrain?s manufacturing plant in Skövde, Sweden. In order to enforce Volvo?s own understanding and control of there own organization, as well as optimize the utilization of the in-house tow trains, the BRO methodology where created. The methodology where created from observations of the currents working environment, analysis of order data as well as a comparison with two similar producing factories.

This examination paper is about the potential for Solar cells on apartment blocks. The technology with using solar cells for manufacturing electricity, has been on the market for a while, but recently the new installations of solar cells has increased. Solar cells are suited for placements on buildings but are expensive to obtain. The municipal real-estate company is interested in solar cells but wants to know more before they invest in the technology. This report contains an account of the solar cell and a guide to how a connection to the grid is accomplished.

The idea to develop  a platform for a PID-controller came from the need to control the temperature in  an espresso machine in a more exact way than a thermostat could perform. In discussions with Syntronic AB the idea developed into PID-control for industrial use. Syntronic AB suggested that the platform should be based on a commercially available processor module to shorten the development time. The suggestion included the use of the microcomputer Raspberry Pi, which supports USB, HDMI, memory card and Ethernet.The work began with establishing a schedule for the 10 weeks of the projects duration, and after that a system specification listing all functions, implementation and limitations was made. When the foundation of the system specification was done, a preliminary system design took shape.Because of the Raspberry Pi´s lack of Analog-to-Digital converter, a circuit board containing Wheatstone bridges, differential amplifiers and a two channel Analog-to-Digital converter was fabricated.

Ledning och övriga anställdas upplevelser av attraktivitet på arbetsplatsen ?Mora of Sweden? looks at how management and employees at the Swedish manufacturing company ?Mora of Sweden? perceive an ideal attractive company and what factors that determine one, as well as how these two groups perceive the situation at their own company. The main purpose of the essay is to compare the management?s point of view with that of the rest of the employee respondents? perspective. While doing so the author concludes that there are several factors such as how the employees feel about their physical working environment as well as their salary, of which the management lacks understanding or perceive differently and that there needs to be more of an open dialogue between the management and the employees..

I studien visar det sig av 40 procent av alla rekryterare kontrollerar kandidater via Facebook. Detta va?ckte fra?gor hos mig, som jag valde att ga? vidare med i denna kandidatuppsats.Syfte: Uppsatsens syfte a?r att underso?ka varfo?r, och pa? vilket sa?tt, arbetsgivare anva?nder sig av internet och de sociala medierna na?r de rekryterar ny personal.

Denna studie ger ökad kunskap om hur en digital artefakt inom sociala medier skulle kunna uppmuntra till äkthet, som en motpol till profilering för att skapa en balans mellan profilering och äkthet. Studien barhandlar området ?hur och varför användare presenterar sig och för sig på ett visst vis i sociala medier?. Detta förstås och diskuteras med hjälp av de två ändpunkterna äkthet och profilering. Studien berör även designerns roll i detta sammanhang.Studien undersöker området genom en litteraturstudie, samt en egen kvalitativ studie i form av semistrukturerade gruppintervjuer.

Teckning är ett arbetsområde som har hängt med från den allra tidigaste bildundervisningen, där den ännu utgör en grundbult i en alltmer svårdefinierad sammansättning. På förtjänstfulla sätt kan man idag kombinera enkla material med modern teknologi, t ex för att skapa uttryck, lösa uppgifter eller underlätta estetisk kommunikation..

In this paper we investigate 67 Swedish buyouts in the manufacturing and retailing sector between the years 2004-2012. The purpose is to measure changes in a set of financial key ratios to see if private equity firms are able to improve performance in their portfolio companies compared to a peer group consisting of other firms within the same industries. Furthermore, we examine if there is a difference in the change of the financial key ratios between private equity-owned firms in the two sectors. The key results are that the private equity owned firms have not outperformed their peers with respect to the chosen key ratios. We also conclude that there is no significant difference in the change of the financial key ratios between private equity-owned firms in the two sectors..

The EU-funded project European Cultural Heritage Online (ECHO) aims to integrateresources from various domains within the field of cultural heritage, and make them availableon the Internet. To accomplish this integration it is necessary to describe the various resourcesin a way that will achieve cross-domain interoperability. This description of digital resourcesis commonly referred to as metadata. The most well known and used metadata standard is theDublin Core Metadata Element Set, a general standard developed for the purpose ofdescribing all types of digital resources. Since the mid-1990's a large number of specializedstandards have emerged in different communities, for example IMDI, designed for detaileddescription of language resources.This thesis aims to examine the possibility of combining a general and a specialized metadatastandard to achieve cross-domain interoperability and at the same time provide a sufficientlydetailed description of language resources for researchers within the field of linguistics.
