En väg till förbättring : Systemanalys ur ett användarperspektiv
In almost every workplace today IT-systems have strong and significant roll in theeveryday work. It is therefore important that the systems have a good functionalityand that they work as an aid for the users. This thesis aims to study the systems atthe company Telge Nät and to analyse them from a usability perspective. By using thisperspective it has been obvious how difficult it is to make improvements on usability,once the system is in place. Even other larger improvements of the systems aredifficult to make at this stage and this is something that the users are aware of.

Politisk identifikation som funktion av ålder och tid på Internet
Det talas idag om ett minskat stöd och identifikation till politiska partier. Forskning visar att unga människor spenderar mer tid och är mer benägna än äldre att använda Internet för att skaffa politisk information. I en enkätundersökning med 125 deltagare i fyra åldersgrupper undersöktes om unga i större utsträckning än äldre identifierar sig med icke-parlamentariska rörelser som för fram sina budskap på Internet. Hos deltagarna mättes graden av parlamentarisk och icke-parlamentarisk identifikation som funktion av ålder och Internettid. Unga hade en signifikant högre Internettid än äldre.
Webbaserat system för dugga
Detta är ett 10 poängs examensarbete på C-nivå vid Karlstads Universitet. Målet med examensarbetet var att utveckla ett befintligt system för webbaserade kurstest så att det också kan användas för duggor. Säkerheten skulle förbättras så att studenter blir tvungna att logga in med användarnamn och lösenord när de ska skriva duggor. Resultaten från de studenter som skriver duggor skulle sparas i en databas. Vi hade också som mål att låta studenter testa systemet och att låta dem fylla i en enkät med frågor om vad de tycker om ett webbaserat system för duggor.Det resultat vi har kommit fram till är ett system som både hanterar webbaserade kurstest och webbaserade duggor.
En kombinerad Organisk Rankinecykel och värmepump integrerat med ett fjärrvärmesystem : Där värme- och elproduktion samt lönsamhet studeras och avfall är huvudbränslet
The demand for district heating is expected to decrease in the future, due to competition from heat pumps and energy efficiency measures in buildings. Development of existing district heating systems is therefore necessary for district heating companies to maintain market shares. This Master?s thesis describes and investigates the heat and electricity production and profitability of a combined Organic Rankine Cycle (ORC) and heat pump that is integrated with an existing district heating system. The studied district heating system is utilizing heat from waste incineration. In Sweden waste constitute 20 % of the fuel mix used in district heating systems, and this share is expected to increase in the future.
Tidsstudier i kalvuppfödning :
Swedish agriculture stands in front of big changes the whole time. As a milking producer you have to adapt and develop the company to these changes and find the best solution. This potential is easy to find if you compare your company with other similar companies. Labour cost is the biggest cost in milking production after the cost for food. Today it is rather easy to measure how many hours per cow different system of cow houses needs, but we do not know so much about how many hours it takes to breed a calf.
To learn more about the labour time with the calves during the first time after the calf was born, I made time studies on five different farms with calf hutches, automatic milk system, large calf boxes, and smaller calf boxes with teat buckets.

Utvärdering av VAV i nybyggt kontorshus
VAV (Variable Air Volume) system has been studied in a newly constructed office-building. The goal for the study has been to evaluate how the ventilations system work in practice, if adjustments can be made to achieve an more energy efficient system and to evaluate if other alternative ventilation systems is to be preferred in the further.The degree project has been executed at Helenius Engineering Firm who is working with the environment, media systems, HVAC and energy in buildings. The building that has been studied is owned and operated by Akademiska hus.Literature studies, visits at site, inventory, review of system documentation, energy analyses, interviews, key figures, LCC, sand energy- and indoor climate simulations has been made to study the building. Where appropriate some tools from Six Sigma have also been used.How to achieve an energy efficient system and a pleasant indoor climate is studied with human health and well-being as base for the indoor climate requirements. Technical support systems such as ventilation systems have to be designed so that an acceptable indoor climate can be achieved.
Designutmaningar för fjärrdiagnostik av fordon
Under de senaste åren har e-underhåll väckt ökat intresse. Det är en underhållshantering där exempelvis ett fordon hanteras och övervakas över internet. Inom detta område finns det olika tekniker. En sådan teknik som vuxit fram under de senaste åren är ?remote diagnostic system? eller fjärrdiagnostiska system.
Motivationsarbete på ett inackorderingshem för missbrukare
Syftet med detta examensarbete var att undersöka vilka faktorer som påverkat acceptansen hos användare, inom den kommunala verksamheten, vid införande av ett datoriserat system. Med acceptans menas att användarna ska kunna utföra sina arbetsuppgifter på ett bra och lätt sätt. Studien har gjorts utifrån användarnas perspektiv.Genom att genomföra en intervjuundersökning på ett flertal kommuner där användarna använder systemet Vabas/Duf, har undersökts hur användarnas upplevda acceptans påverkas av faktorerna delaktighet, användbarhet och lättanvändhet, vid införande av ett datoriserat system. Delaktigheten vid införandet av ett system innefattar även information och utbildning.Resultatet från undersökningen visade att delaktigheten ökade användarnas acceptans. Ingen avgörande slutsats kunde däremot dras mellan acceptans och faktorerna användbarhet och lättanvändhet, då resultatet från de båda grupperna inte visade någon märkbar skillnad..
"Dom kallar oss invandrare!" : En undersökning som bygger på hur ungdomar av "andra generationens invandrare" identifierar sig själva.
This investigation is aimed to analyze and gain insight into how young people of the "second generation immigrants" identify themselves in a society where they are seen as immigrants of the environment in view of the name. Also, how they identify themselves during trips to their home/country of origin are of relevance to see if they are affected in their own identification, depending on how they believe they are seen from the outside.Through a survey, the statistics were produced, which serves as a preliminary to the larger part of the investigation where six individuals were interviewed in order to give deeper answers to the questions sought. The answers that emerged were then analyzed in relation to selected theories.In connection with the investigation it has emerged that the young people in question often identify themselves in such a way that they think that the surroundings look at them. It is in relation to how others see them as they see themselves, which creates a distance between the surroundings and themselves. With increased knowledge on both sides, this distance between the environment and the young people in this investigation maybe could reduce..
Gymnasieungdomars identifiering med den egna sexuella läggningen : Självkänsla, nära socialt stöd, ifrågasättande
Under ungdomsåren sker stora förändringar, både fysiskt och psykiskt. Utforskandet av sexualiteten blir mer aktuell och den sexuella identiteten och den sexuella läggningen kan genomgå förändringar. Viktiga aspekter för att identifiera sig med den sexuella läggningen anses av vissa forskare vara självkänsla, nära socialt stöd och ifrågasättande. Syftet med denna studie är att finna svar på hur mönster av dessa faktorer kan påverka den sexuella identiteten bland gymnasieungdomar. Studien genomfördes med en kvantitativ ansats.
Trapphus i träplattform för CBBT
Industrialization of construction is by some considered to be a solution to the building industry's problems about the lack of quality, high production costs, low productivity and poor environmental adaptation. Meanwhile, industrialized construction partly earned a bad reputation after the million housing program. As large-scale projects where promoted during this period, it worked very well to use the technique of construction elements. In the mid seventies though, criticism arose which claimed that the aesthetic qualities had been deprived in the corporates effort to make housing production as efficient as possible.Tyréns, Derome and CBBT (centre for building and housing in wood) cooperates in a development project to develop a building system for 4-8-storey buildings, consisting of three platforms: a technology platform, an IT platform and a processing platform. The technology platform consists of flexible, industrially built flat modules of wood and from this platform the subsystem stairwells, is broken out.
Presentation och utvärdering av CollMX : Ett transparent kollaborationsverktyg
Organisations and projects use CSCW/Groupware systems for collaboration purposes. These systems and applications are in many cases using a non-transparent GUI, witch is also hard to learn. This paper present a novel system that aims towards being transparent and easy to use. This system, called CollMX, will be evaluated and different ideas for future development will be presented. The evaluation and ideas are generated by an empiric evaluation and research in different areas related to CSCW. The research does not only focus on the area of CSCW, but also extends towards the Web 2.0 and ideas about awareness..
Hur fungerar vårdens IT-system egentligen? : Jämförelse av elektroniska patientjournalsystem
To support, enhance and, in the future, develop the activity within the county councils in Sweden, IT support systems are currently used to a large extent. The need to document is central to the health care organizations and the counties have come a long way in the introduction of electronic patient record systems (EPR). The aim of the EPR systems is to support the care processes and the clinical professions in their work.This is a master thesis in the area of human-computer interaction (HCI), Department of Information Technology at Uppsala University. The aim of the thesis was to describe and compare the five most common EPR systems in Sweden. The comparison will focus on some usability aspects and on how well they support the users in their clinical practice.
