Tanken bakom examensarbetet var att undersöka huruvida de äldre system som finns i bruk ute i organisationer idag uppfattas som ett problem samt vad som i sådana fall görs åt problemet. Ett flertal författare har under åren förklarat hur förändringar i system leder till en försämrad struktur vilket förr eller senare orsakar ett försvårat underhållsarbete av system. För att ta reda på hur väl litteraturen stämmer överrens med svenska organisationer så har vi intervjuat fyra respondenter för att få deras syn på problematiken. Denna har sedan jämförts och diskuterats mot de premisser vi funnit i litteraturen. Det har framkommit att det litteraturen inom området menar, stämmer till stor del med det våra respondenter berättat.

Arbetet ett företag lägger ner för att komma fram till ett beslut om en större investering i till exempel nya maskiner är oftast omfattande och ett resultat av ett strukturerat arbete med klara strategier för att i största möjliga mån uppfylla behovet som orsakade anskaffningen. Däremot har en investering i informationsteknologi av olika anledningar inte setts som vanliga investeringar utan ofta genomförts utan en ordentlig utvärdering. Med denna uppsats ville vi försöka ta reda på om det verkligen förhåller sig så att företag anskaffar IT-system utan att göra någon ordentlig analys av de problem eller behov som förorsakat anskaffningen eller om de följde de metoder och modeller som finns tillgängliga för att komma fram till ett beslut om anskaffning av ett IT-system. Vi utförde vår undersökning vid tre produktionsföretag som hade anskaffat liknande system. Vid vår analys valde vi att applicera förändringsanalysmetoden, FA/SIM och Simons vedertagna beslutsprocessmodell på det empiriska materialet.

Sveriges Radio stores their data in large archives which makes it hard to retrieve specific information. The sheer size of the archives makes retrieving information about a specific event difficult and causes a big problem. To solve this problem a more consistent use of metadata is needed. This resulted in an investigation about metadata and keyword genera-tion.The appointed task was to automatically generate keywords from transcribed radio shows. This included an investigation of which systems and algorithms that can be used to generate keywords, based on previous works.

In this work we study how the information provision should be organised in a new smaller size Swedish university college in a town without previous academic traditions. Specifically, our aim is to propose a possible model for information provision in Campus Helsingborg which is currently under construction. The study consists of two parts: literature review and empirical investigation. In the literature review we summarise a selection of articles about traditional and untraditional practically realised ways of information provision in nineties. The empirical investigation consists of 19 interviews with students, teachers and librarians from Kalmar, Halmstad and Helsingborg.

With the prospect of future construction on the Skutskär Pulp Mill property, Stora Enso Fine Paper has initiated an investigation of soil contaminants and a risk assessment of these contaminants. A soil and groundwater investigation has therefore been conducted on an open area of about 16 000 square meters, situated between the current wood room and digester house. To be able to integrate this study into an investigation for the whole industrial property, the study has been carried out as a phase 2 study according to the Swedish Environmental Protection Agency?s Methods of Inventories of Contaminated sites (MIFO).The site investigation has involved soil and groundwater sampling, together with the analysis of heavy metals and organic contaminants. The degree of hazard posed by the contaminants, the level of contamination, the potential for migration of the contaminants, as well as the degree to which protection of human health and the environment is required in the area, have been weighed together for an overall risk assessment of the area with regard to human health and the environment.The investigated area was built up by filling in the coastal waters.

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.

Holmen Skog is one of the largest forestry companies in Scandinavia and they depend heavily on a large network of forest roads for production and logistics in connection to their forestry operations. The company recently introduced a new system for planning of road management. The system will also be developed with the intention to facilitate the monitoring of actions performed by road contractors. This report will provide information to support future decisions regarding further development of the system, after its introduction. In addition to a presentation of results from interviews, the report also provides a smaller study of the different subjects associated with roads, process work and process development. The study is largely based on interviews with road contractors that perform work for Holmen Skog today.

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 purpose of this master thesis is to evaluate how internal vehicle information inScania buses and trucks can be used for evaluation of driver performance regardingfuel economy, vehicle wear, traffic safety, emissions and cargo damage. To someextent it was examined whether this information could be used for training the driverto a better driving style. In addition, a prototype for such a system was developed.By first defining what distinguishes a talented driver and how he/she differs from apoor driver, followed by a study of the internal vehicle communication, a system thatin real-time gathers and interprets vehicle data could be developed.The resulting system can with reasonably high reliability detect a number of trafficevents (such as braking, lane changing or hilltops). At each such event, the driver?sbehaviour can be evaluated.

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.

AbstractThe research project Liberation, supported by the European Commission under the Environment and Sustainable Development Programme (Fifth RTD Framework Programme) aimed at developing a decision support system for ecological risk assessment of contaminated sites has proposed a tiered system including the triad method. This method integrates contaminant chemistry and bioavailability analyses with observed ecotoxicological effects in soil and groundwater. In this study the triad method was used to perform a risk characterization of a former surface treatment and metal industry, now used for the student union buildings of the Mälardalen University in Eskilstuna, Sweden. On the site, high concentrations of copper, zinc and nickel have been detected in the soil in a preliminary investigation of contaminant levels with XRF. For performing the risk assessment of the site according to the triad method, contaminant bioavailability, soil metal concentrations and soil toxicity were determined and an ecological assessment was carried out on four selected soil samples (one reference soil and three samples with low (B), medium (C) and high (D) contaminant levels). Contaminant bioavailability was measured through leaching (ISO TC 190/S7) and biouptake tests (DGT).

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.
