Förebyggande effekter av fysisk aktivitet på depression : ? en litteraturstudie
Objective: To study the evidence on physical activity (PA) as an effective preventive strategy for depression.Methods: A search of electronic databases was performed for articles between 2007 and 2012, both original research and review articles, concerning the link between PA and depression on children, youth and adults. Three reviews, five longitudinal and two cross sectional studies were included.Results: PA reduced the likelihood of depression in many studies and a sedentary or inactive lifestyle increased the risks for mental health symptoms such as depression. One study showed that low PA in childhood increased the odds of depression as an adult and other studies on teenagers saw a connection and mediation between PA and self-esteem whereas physical fitness showed no mediating effect. Many of the studies and reviews point out the insecurity regarding the dose-response association and the difficulties in defining causality.Conclusion: PA might have a preventive effect on depression. Some evidence exist to support that PA in childhood prevents depression in adults.
Realtidsoperativsystem på mätinstrument.
Emwiro Vibe is a complete system for seismic measurements. The functionality of the system was before the completion of this project handled using a software contruction based on a state machine. Emwitech, the company developing Emwiro Vibe, expressed a desire to replace this solution with a real-time operating system (RTOS). The project consisted of two parts. Firstly the existing software was studied, available RTOSes was evaluated, and the RTOS most suitable for the application was selected.

Utformning av förfrågningsunderlag vid totalentreprenader
Two elementary schools are now being built in Gråbo (in the municipality of Lerum),Röselidsskolan and Ljungviksskolan, which are both designed with solar thermalcollectors for the schools domestic water heating. During the summer while thelargest amount of solar heat can be generated, the activity hence the domestic wateruse in the schools are heavily reduced. Both schools are connected to the local districtheating system which makes it possible to use the solar collectors to deliver heat tothe district heating.The purpose of this thesis is to evaluate the two systems mentioned above and todetermine which system is more suitable to apply on a school. The building whichconditions were used for this evaluation is Röselidsskolan.A solar heating plant of each system type was dimensioned from the expected andknown conditions of the building. The purpose with the dimensioning was to makethe solar plants replace the ordinary energy source as much as possible.
Reviderade räkenskapers betydelse för bankers kreditgivningsprocess?
In 1983 Sweden passed a law stating that all limited liability companies are to be included into a mandatory auditing system. According to the EEC, courts fourth amendment, each country has the right to decide whether to exclude a mandatory auditing system for smaller companies. Audit reports in Sweden are considered to be very important for the bank crediting system. Should this be eliminated, it would be more difficult for banks to trust an audit. The significance of calculated audits is questioned in regards to the banks accrediting system.

Energianalys av tryckluftsystem : så kan Billerud Skärblacka AB spara energi på tryckluft
Compressed air is a low efficiency media, and is thus very expensive to produce. This thesis work began by mind mapping how to create savings on the compressed air system at Billerud Skärblacka AB.

Modelering av Wideband : Code Division Multiple Access
Today wireless transmission of data is becoming more and more popular and the need for faster transmission rates is increasing. Since the bandwidth is limited it is important to try to use it to the fullest. CDMA is a technology that allows multiple accesses on the same frequency and time thus making it very bandwidth efficient. The CDMA technology was first introduced in the second generation?s cellular systems but has since then been improved and is reused in today?s 3G systems as Wideband CDMA.
