Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.

In recent years, several problems in the field of assistive device have been lifted. To manage the development Beslutsstöd (Decision support) has emerged as a systematic working method. Beslutsstöd is designed as a guideline and serves as a tool for physical therapists and occupational therapists in the prescription process of assistive devices. Beslutsstöd thereby aims to improve the quality and effectiveness of the prescribing process of assistive device in the organization of the municipalities. An implementation evaluation about how the implementation of Beslutsstöd in the municipalities did proceed has not been done.

In the field of IT-forensics you may often get to analyze different types of digital devices. One ofthese devices is the GPS navigation system. Nowadays GPS technology is getting more and morepopular and is included more frequently in different types of devices. With this article we want topresent the differenent obstacles and possibilites that a forensic investigator is presented with in thistype of investigation. We will be comparing different software suites and make use of forensic toolssuch as EnCase.The reader should get some understanding of the methods there are for analyzing one of these devicesand what problems that may occur in the investigation process.The article presents how the investigator can use different methods to gain information such as recentroutes, favourite destinations and other information that may be stored on the device.

This thesis is basically a design project aimed to find a safe and reliable automatic safety device, which is designed to be suitable for highly automated industrial situations. This device fits with ABB / Jokab Safety?s fence systems. These are built up around machines to create safety distances. The automatic protection device assist the operator in situations when loading or going in and out of the danger zone.

EW26 is a Bachelor thesis carried out by students, Jessica Blomberg, Sara Danielsson and Mikael Johansson, during the academic year 2010-2011 at the Innovation Engineering Program of Halmstad University. The project was conducted in close cooperation with Ergosafe AB.Ergosafe develops, manufactures and sells electric sliding windows. Due to the company?s current expansion phase they want to increase their product range. The company has identified a need for large windows that moves vertically.

The purpose of this work is to design and construct a device able to measure the mechanical attrition of oxygen carrier particles. Those particles are used in chemical looping combustion and in the present situation there is a lack of knowledge in how the attrition process work and in which extension. To find already tested solutions trying to answering this problem a literature study wascarried out and the best solution found was the so called Grace-Davison Jet-Cup method. This method is supposed to emulate the attrition caused by a cyclone separator and its advantages are that it is possible to use small test amounts, 5-10 g, and a thirty minutes long test will be enough to acquire useable results. An device was designed based on the Jet-Cup method with some slight modifications.

Något som har blivit en stor fråga på sistone där arbetsgivare tvingats ta ställning är huruvida anställda har tillåtelse att använda sina privata enheter på arbetet eller inte. Användandet av smarta telefoner och surfplattor i privatlivet har på bara några år ökat relativt drastiskt. I och med detta så har viljan också blivit större bland arbetare att kunna utnyttja sina privata enheter även i arbetslivet. Detta fenomen kallas för Bring Your Own Device och implementationen av detta kan orsaka vissa problem och kan exempelvis påverka nätverkssäkerheten. Arbetet ämnade, att genom en enkätundersökning, undersöka hur pass vanligt det var att man tillät privata enheter i arbetet bland Sveriges kommuner och landsting.

The objective with this project was to design a new lifting aid connected to toilet chair.A questionnaire distributed at three homes for aged people indicated that there was an interest in a mechatronic lifting device.Since existing products have limited tilting functionality, the new design was chosen to introduce lifting by motorised tilting of the sitting platform. The mechanical construction was analyzed based on a maximum load caused by a person with weight 160 kg. Two linear actuators were used to control the tilting/lifting of the sit ?place, making standing-up easer.Finally, 28 persons tested the new lifting device and gave their impressions. Many appreciated the safe, stable lifting speed.

Syftet med denna studie är att få en grundläggande kunskap kring begreppet bring your own device. Eftersom ämnet är väldigt nytt och att det finns en viss okunnighet kring begreppet är det intressant att ta reda på varför BYOD är en uppgående trend, hur svenska verksamheter tänker inför tillåtandet, vilka krav som ställs och vilka problem som följer. För att komma fram till dessa slutsatser har intervjuer genomförts på tre olika verksamheter. Varav en verksamhet har tagit sig an BYOD och de andra två planerar inför tillåtandet av BYOD. Det har även genomförts intervjuer på både unga studenter, unga i arbetslivet samt en jurist för att få en tydligare bild av företeelsen.

This report describes the construction work of a radar antenna for the radar systemCARABAS. CARABAS is a long wave airborne ground radar that has been developed bySAAB Microwave Systems and will now be mounted on a small helicopter, Schweizer 300.The antenna should be able to fold up and down. When the radar is in use the antenna islowered and under transport, start and landing the antenna is folded up. An emergency dropfunction should also be included in the design of CARABAS III.The extent of this report includes construction of the antenna, frame structure attached to thehelicopter, mechanism for folding the antenna up and down and mechanism for emergencydrop function. The mechanical design of the antenna and frame structure is based on modaland stress analysis, vibration measurement of Schweizer 300 and frequency analysis, andcalculations regarding aerodynamic drag and mechanics.The exciting frequencies of the helicopter and accelerations at those frequencies weredetermined by vibration measurement and frequency analysis.

Syftet med denna studie är att identifiera hot, risker och konsekvenser kopplade till BYOD samt undersöka hur dessa kan lösas. BYOD är idag något som införs i allt större utsträckning hos olika företag världen över. Många är intresserade av alla möjligheter det kan frambringa, dock blundar allt för många för alla de olika hot och risker det samtidigt kan medföra. Utöver det tar vi i denna studie även upp hur man kan skriva en säkerhetspolicy kopplad till området BYOD. För att komma fram till våra slutsatser har vi förutom den teori vi samlat in fått hjälp av Jan-Olof Andersson en av Sveriges främsta IT-säkerhetsexperter med att skapa en riskanalys och en arkitekturbild.

The report addresses four main tasks, situation analysis of the company's total costs and transportation volume, cost analysis associated with the adjustment of the filling ratio, transport costs for the expansion and new expenses on a combination of expansion with new adjusted filling ratio.  Increasing transport costs for the company was the main reason for the request of the current situation analysis. A survey of the total cost with the actual volumes and transport provider pricing is the basis of the analysis that extends from May 2006 to October 2008. The results show an increase in costs, both overall expense and per cubic meter of transported goods. Volume spreads, trends, and seasonal variations are according to our and the company?s expectations.
