The purpose of this master thesis is to examine a proposal for basic class 4 in UDC, which has been empty since 1964, and to pick out a negotiable subject for that proposal. The proposal is analysed from a theoretical perspective based on principles created by S. R. Ranganathan. Three principles are used.

The aim of this study was to evaluate the stir drying method, for drying of grain during Swedish conditions. The evaluation was done during the harvest year 2004, on four farms with stir driers. The driers were evaluated for their energy consumption, design, stirring effectiveness and how much time the farmer has to spend on every tonne of grain. A comparison was also done with conventional Swedish high temperature driers. Totaly six batches of grain from stir driers were examined, mostly winter wheat, but also barley and wheat.

Jag har studerat fenomenet Bring Your Own Device (BYOD) och hur detta har implementerats i svenska företag. Syftet har varit att beskriva vad BYOD kan innebära i olika verksamheter utifrån vad som kan anses inkluderat i trenden. Jag har även studerat drivkrafterna bakom implementeringen samt vilka företagsspecifika förutsättningar som kan påverka lösningen.Undersökningen har genomförts genom en fallstudie och tre företag har studerats. Den empiriska undersökningen har visat på en stor skillnad mellan företagens valda lösningar och även tydliggjort vilka faktorer som kan komma att spela roll vid utformningen av en BYOD-lösning. I analysen har sedan de olika lösningarna jämförts med varandra utifrån ett underlag som tagits fram ur litteraturen.

Cochlear implant has become a common treatment for people with severe hearing loss. As the field of cochlear implants is developing rapidly a larger group of patients will be implanted. Therefore, it can be of interest to identify which complications are most frequently occurring. Objective: The aim of this study is to identify and present the most common complications in cochlear implant treatment and to identify surgical issues that have to be addressed during implantation. Method: A review of retrospective case studies regarding complications has been made.

In Sweden plans to build high speed railways have been around since the early 1990s and the planshave developed to be more precised since. The future Swedish high-speed rail network is supposedto consist of two lines. Götalandsbanan; from Stockholm to Gothenburg, and Europabanan fromJönköping through the Öresund Region to Hamburg.The description of the aim to build high-speed railways in Sweden has in former reports always beento achieve rapid passenger traffic between big Scandinavian cities and Europe. There are almostnothing mentioned about the possibilities of high-speed transports of cargo on these railways. Thisstudy aims to clarify the freight transport market for Götalandsbanan and Europabanan.Today there is only one transport system with high-speed freight trains.

The amount of cargo has since the 1970s increased in Sweden and the road traffic accounts for a large part of the transported volume. In Stockholm County the amount of cargo is calculated to be doubled in size from year 2001 to 2020 which means a greater need for transport is required. Much of these transports are being carried out by haulage companies of varying sizes which acts externally as carriers for their customers. All of this despite a greater awareness, laws and demands regarding environmental performance.The trend shows that the haulage industry in Sweden are moving towards fewer but larger haulage companies, which means that the competition is getting tougher for the smaller haulage companies. Smaller haulage companies and research about their competitive strategies is a neglected part of this industry.

The use of mobile devices has increased dramatically in recent years and the development of newtechnologies has made it difficult for developers to know what screen size and device the visitor isusing. This has resulted in the fact that today there is a problem with the interface for web pages onmobile devices. They are not adapted to the flexibility required for the interfaces to be recognizedon various mobile devices. Instead of developing two separate web pages, where one is designed formobile devices and one for desktop and keep them both continously updated, responsive webdesign simplifies the work process. Responsive web design is a flexible and dynamic interface thatadapts to mobile device and screen sizes.

The parallel bars is used in physical therapy and is mainly used for patients who have to train walking and balance after a stroke or an operation. It consists of two long handrails with two legs on each handrail. These legs go down into two ground-plates and are locked at the wanted height with a pin. The parallel bars is an appreciated device and is used on a daily basis in many care units.The main issue with the manual parallel bars is that it is very difficult and heavy for a single person to adjust the height of it. If a larger adjustment of the height has to be done, the legs have to be adjusted one at a time otherwise the they will be locked.

The municipality, of Gatukontoret in Local government of Borås has in the long run, a required need to look after the current heating devices (the gas production plant) in sewage treatment plant, called Gässlösa. The practical work of the examination is about, trying to find a better way to take care of the current heat recovery. That may be one way or another, rather easy to implement in the existent construction.Through the work to increase the efficiency of the gas engine, implement of some external cooling system by heating exchange device. That gives an opportunity to heat (primary) the digester, (but even all internal public areas) with its own superfluous heating.The report shows that if the management group may invest 422 704 crown to implement a heat exchanging device, it gives more space to reduce the need to buy expensive external energy. Gatukontoret´s pay off time, for buying machines, is 20 years, with reservation to calculate with 4 percent internal interest, leads to the yearly mount of 31103 crowns.If Gässlösa increases the gas engine time in (effective) duty approximately (correspondingly) 48 hours a month the entire investment will generate a profit in January in year seven after the implementations.

Detta examensarbete har genomförts i samarbete med Sourcecom Svenska AB. Sourcecom Svenska AB arbetar med kommunikationslösningar inom IT-kommunikation, IT-säkerhet och telefoni. Examensarbetet går ut på att undersöka konceptet Bring Your Own Device (BYOD) och föreslå olika lösningar beroende på företagets informationssäkerhetskrav. För att förstå konceptet BYOD behövs först en inblick i hur ett policybaserat system fungerar. Rapporten undersöker och förklarar tre olika Network Access Control (NAC) lösningar som är policybaserade.

Radio frequency identification (RFID) is a versatile wireless technology usedworldwide. The fields of applications are many and its popularity constantlygrows due to smaller in size, better and less expensive components. RFID isused to identify, track or share information about an object using radio waves.This master thesis describes the process of designing and implementing ahandheld UHF RFID reader. The goal was to, based on a UHF RFID-chipdesign a fully functional, small in size and power efficient device. Amicrocontroller provides the user interface and is also used to control theRFID-chip and a Bluetooth device.

The thesis is an examination of the methods that are appropriate and long-term choice to obtain clamping force and secure screw joints in production. The employer, Scania CV AB, transmission manufactures axle gears to all trucks produced in Södertälje. One of the most common assembly elements is screw joints, where the clamping force is essential to achieve a secure joint. Current methods to secure the joint is due much of the friction effect and is an indirect method to measure the clamping force. The clampforce accuracy becomes more widely with torque angle control.

Transportbranschen är en av de branscher som ofta förekommer i debatten kring klimatförändringar, men de är även en av de branscher som ligger långt fram i utvecklingen vad gäller redovisning kring hållbar utveckling. Syftet med detta examensarbete är att utreda vad som ger en lyckad eller god hållbarhetsredovisning. Med lyckad eller god menas att hållbarhetsredovisningen bidrar till att ge företaget legitimitet från sina intressenter samt att hållbarhetsredovisningen tillgodoser intressenternas informationsbehov och att företaget lyckas kommunicera sin hållbarhetsredovisning till sina intressenter. Detta skall göras genom att utifrån teorier kring intressenter, legitimitet och kommunikation analysera riktlinjer som finns för hållbarhetsredovisning samt genom att studera två fallföretag inom transportbranschen, vilka har prisats som goda förebilder. En lyckad hållbarhetsredovisning är en redovisning som följer de uppsatta riktlinjer och standarder t.ex GRI och FN:s Global Compact, som idag finns och som erbjuds till företag som vill använda sig av hållbarhetsredovisning.
