?På resande fot? - En studie om hur individer stöds och upplever mobilitet i sitt yrkesliv
The use of information technology (IT) has expanded to be available in large parts of the society.With reference to this mobility has become an increasingly used term, which reflects changes in our lifestyle, travelling and mobile artefacts. The technology development that has occurred in recent decades has made it possible for people today to be more mobile than before as they no longer are tied to a fixed workplace. Mobility has changed the ways to lead, coordinate andmeasure work productivity in organizations. It has also added new ways of working. The mobile development also means more challenges and changes in today?s modern organizations.The purpose of this paper is to analyse how employees in a consulting form use mobile technology in a work context, how they interact with others and how individuals reason about mobility.
Energieffektivisering av äldre byggnader : Konstruktion & ventilation i Växjö kommunhus
Inom EU vill man sänka energianvändningen med 20 % till 2020.Växjö kommunhus har gamla och ineffektiva installationer, samt ett dåligt isolerat och otät klimatskal.Denna rapport undersöker vad för slags inverkan byte av installationer, samt byte av klimatskal, har för inverkan på kommunhusets energianvändning. Till detta har energiberäkningsprogrammet VIP-Energy 1.5.5 använts.För att sammanfatta resultatet av arbetet så är det mest effektiva och lönsamma alternativet att byta ut installationerna, samt att kylbehovet ökar då man kraftigt isolerar detta hus..
Beyond Smart : A Quest for the Humane
Where is technology heading? And how will our behaviors towards these new innovations look? This project questions the direction of ?beyond smart? products, through scenarios within our everyday life. The work is both critical and speculative. Speculative in the sense that it is speculating in how a future scenario with ?beyond smart? products would look like.
Klickers ur ett studentperspektiv : Studenters uppfattning av klickers vid Uppsala universitet
Audience responese technology (ART) often called clickers are becoming more common, not only internationally but also at Swedish universities.

HDR och Tone mapping i automatiserade tullsystem
This report is about how HDR (HighDynamicRange) can be created and used in combination with Tone mapping. This work has been carried out together with Kapsch TrafficCom AB in Jönköping.The objective of this project is to:Evaluate and investigate the effects given to pictures by HDR and tone mapping.Evaluate if the technology may lead to improvements in Kapsch?s systems.To construct a program which is able to handle some form of tone mapping or HDR-algorithm.These questions will be answered in this report:What kind of effects has HDR and tone mapping-algorithms on pictures?Can the HDR-technology give better data in Kapsch?s systems?The research method used in this report is called action research. This means the authors has investigated the technology by reading different documentations and by testing different algorithms to see what kind of result they give. The report describes some of the tests made to see if the technology is appropriate in Kapsch?s system.There is two smaller reports made by the authors which documenting some of the work.The first report describes the work with different settings for a camera to create pictures with HDR-quality.
Från dykbåtar till ubåtar : Ubåtsvapnets utveckling 1945-1960
From underwater boat to submarine ? The development of the Swedish submarine service 1945-1960 The scope of this essay is the development of the Swedish submarine service during the period 1945-1960. The aim is to answer the following questions:- What kind of new technology did Sweden acquire when salvaging the German type XXI submarine off Gothenburg at the end of World War II?- In what respect did this technology differ from that of the Royal Swedish Navy and did it subsequently contribute to the tactical and operational development?- What tactical and operational development was accomplished between 1945-1960?The timeframe, 1945-1960, was chosen since this is when the analysis of the salvaged type XXI submarine and related effects was conducted. Furthermore, it is also during this time that the Swedish submarine service is beginning to evolve as a result of the new knowledge mentioned above and the experiences made by both the allies and the Germans during World War II.The theoretical framework primarily refers to the theories on naval warfare by Sir Julian Corbett.
Ekonomi i Passivhus : En studie av två verkliga byggnader
The aim of this report was to investigate the economy of passive houses. The work was focused on economy in total and on the economy of different components such as windows, insulation, heat exchanger and the air tightness of the climate shell. No attention was paid on the comfort factor or to the impacts on the environment.Two houses, aspiring to be passive were chosen; A big one and a small one. Hence, comparisons considering the size of the building have been possible to do as well.The comparisons were made by calculating ?break even? between two concepts; passive and BBR- concept.
Torrfoder till katt : påverkan och konsekvenser
The cat has evolutionary become an obligate carnivore. Today it is common to feed the cat a dry food. Studies have shown that the dry formula can have negative consequences for the cat. A literature study where conducted to investigate whether the cats origin makes it incapable to compensate for the changes a dry food entails. The impact and implications regarding water intake, energy intake and blood glucose concentration when feeding the cat dry food where examined.

Erfarenheter från flerbostadshus som passivhus : En handflata och sex värmeljus
All new households were to be constructed with "near zero energy house standards" (NZE-house) by the year of 2020. The ambition to construct energy-efficient buildings had to increase rapidly in the spring of 2013.The purpose of this report was to increase the interest for building contractors to construct apartment buildings with passive house standards. By locating and evaluating experiences from an existing passive house a case study including interviews, field visits and document analysis was made. Research of literature regarding other passive houses in Sweden also helped to answer the following questions:- What positive and negative experiences have the study of the passive house meant to the involved stakeholders and residents?- What improvements can be made based on identified experiences?- How can an apartment building be designed as a passive house based on possible improvements?By collecting good and bad experiences, as well as improvements and potential design proposals, a diagram was created designed as a tool for developers when constructing apartment buildings with passive house standards.
Värmesystemsutveckling
In cooperate with Asko Cylinda we have developed a new heat system too short the process
time and reduce the energy consume in a dishwasher and still have it too be a class AAA.

the market, If they want too keep that position the product developed of new innovations will
be very important. The systems we have developed are more effective and reduce energy up
too 25 %. The process time is reduced too less than two hours, from the today two and
half-hour. The solutions are too heat up the rinse water and the dishwater at the same time,
with a new heating system and it make are solutions unique and effective. Its good for the
dish and the environment.
Konvertering från direktverkande el i kommersiella lokaler : Ekonomisk och hållbar utveckling
Buildings worldwide account for 40 % of the total energy use. Climate change is of increasing importance, but few are willing to reduce their standard of living or get a higher cost for the change. Energy efficiency of existing buildings gives the greatest benefit economically and environmentally. The real estate company Klövern AB manages 46 properties in Karlstad. Heating is the major cost of the total operating costs of real estate. Rising energy prices increase the need for Klövern AB to improve energy efficiency and to investigate alternative sources of heat.
