This report is an outcome of a master degree project at Linköpings University in co-operation with Micronic Laser Systems AB. The purpose with this master degree project was to investigate how to implement a receiver in a data transfer system. The system consists of several data channels, where every channel consists of three parts: driver, transmission lines and receiver. The driver send low amplitude differential signals via the transmission lines to the receiver that amplifies and converts it to a single-ended signal. The receiver has to be fast and be able to feed an output signal with high voltage swing.

Lotsbroverket is the largest wastewater treatment plant on the Aland Islands and it isdesigned for handling wastewater from approximately 30 000 persons. In 2011,Lotsbroverket produced about 2800 m3 of dewatered sludge. The sewage sludge that isproduced is transported to a contractor where it is processed to eventually be used e.g.in the construction of green space. This study aims to investigate available applicationoptions in terms of the sewage sludge that is produced in Lotsbroverket. The main aimis to study the feasibility of using the produced sewage sludge as a fertilizer in theagriculture of the Aland Islands.The sludge already fulfills limit values for heavy metals in accordance with the Act"The Aland Government´s directive on the use of sewage sludge in agriculture." Inorder to clarify the sludge content of pharmaceutical and organic substances it isrequired that the substances are identified and a risk assessment is performed.

This study was made as a part of a Feasibility study on a polishing wetland at Rimbo wastewater plant (wwp) in Norrtälje municipality. The wwp had to decrease the nitrogen discharge to reach the limit 15 mg tot-N/l. The nitrogen in the outlet was mainly in the form of nitrate, hence the wetland mainly ought to support denitrification. The proposed area for the wetland was situated right next to the wwp and was already in the municipalitys posession. One aim of this study was to examine what spieces of plants needed to achieve highest possible denitrification.

This Master Thesis is a product development project that has been carried out in cooperation withSvea Teknik AB. The company has developed an apparatus for attachment of a keel to a hull base ofa boat.

AbstractSkanska Sweden has decided to split the organization that earlier handled both large and small projects into two different subsidiaries. A consequence of this is that all construction service handling will from now on be enforced under the name Skanska Direkt AB. The management of Skanska sees this as an opportunity to develop the organization and in the long term achieve higher earnings.   The task which Skanska in connection with the reorganization wanted to be investigated was a proposal on how the organization of work with the insurance work in the future should look like.The organization that is handled is from production manager to professional workers and includes damage handling that has been obtained from insurance companies in the southern and northern parts of Värmland. The purpose with this work is to present a different kind of view to the problem with developing this branch of the company. The main target was to work out a proposal of an organizational plan for the damage handling in Skanska Direkt AB that is possible to apply, less sensitive for dismissals, results in higher earnings, obtains higher customer satisfaction and also a staff stab that develops their skills at their own.The report and work progressed as following:Opening theory study of strategies to obtain the objectives set.Restructuring of existing organization with theories as support.Interviews with the actors involved to verify feasibility of the developed organization plan  Organization chart, the result of work means that some workers at each location shall be responsible for a small group of workers and work independently. They shall manage the process of invoicing and calculate costs at the same time as they work out on the workplace.

In the EU the amount of waste increased by 14 percent during the years 2000 to 2010. EU?s target to reduce waste generation runs parallel with the aim of increasing the efficiency and profitability aligned with energy recovery. In Sweden the energy recovery through incineration is increasing steadily, and 46 percent of the municipal solid waste (MSW) is treated by combustion. This report aims to examine the profitability of processing MSW into Refuse Derived Fuel (RDF) from an economic-, energy- and environmental perspective.

At the moment in central Täby there are small district heating network operated by Fortum Heat. The distribution network has an annual heat demand of about 70 GWh, which is supported by the network's two plants, Galten and Farmen. Täby as a region is rapidly growing and there are grand plans to develop the area. Estimated market potential for a future district heating expansion in Täby is very high and as early as in 2007 Täby decided to invest in a large-scale expansion. In autumn 2009 Täby did a procurement process, known as the ?Täby initiative?, to find a partner that could implement those expansion plans. To secure a cheap basic production the partner also need to build a power plant at Hagby recycling center. Despite high interest during initial state of the process, only one procurement offer were received and Täby suspended the contract in March the following year.

This thesis examines different methods for the cooling of data centers. Several means of cooling with the refrigeration cycle have been studied, as well as the feasibility of using free cooling in different parts of Sweden. In addition, the possibilities of transferring excess heat to a nearby district heating system were investigated. It was found that in all investigated cases except two, the data center could be cooled solely with free cooling for at least 300 days a year when only the outside air temperature was considered as a constraining factor. The limit was then set to 20 °C.The vast majority of all district heating systems in Sweden get little to none of their heat from other excess heat sources.

Ocean Thermal Energy Conversion, OTEC, a technology using the temperature difference between cold deep seawater and warm surface water, can extract the work in the form of electricity. OTEC gives also synergies of drinkable fresh water. The temperature difference has an impact on the efficiency of the technology, which means that the feasibility of OTEC is geographically limited. The project intends to explore the possibility of replacing the atoll Tarawa?s present electricity generation with an OTEC plant and to explore synergies. In the present situation all of Tarawa?s electricity is generated by fossil fuels.

En miljon människor i Sverige dricker för mycket alkohol vilket kan leda till försämrad hälsa, sjukdom och skador. Sjuksköterskor möter patienter i olika omvårdnadssituationer inom hälso- och sjukvården. Syftet med denna studie var att belysa vad som underlättar och vad som hindrar sjuksköterskor att ställa frågor om alkoholkonsumtion i möten med patienten. Litteraturstudien baserades på 10 artiklar funna via de två databaserna Cinahl och PubMed. Artiklarna har granskats och analyserats och i resultatet framkom tre kategorier vilka har huvudtema och undertema.

I dagens verksamheter, med flera tillhörande affärsprocesser som sträcker sig över olika arbetsområden, finns det ett behov av väl fungerande IT-stöd som är anpassat för den enskilda verksamheten. Affärssystem är sådant IT-stöd som används för att stödja, förenkla, planera samt följa upp en verksamhet på. Med flera skilda funktioner som täcker de flesta affärsprocesserna, är förhoppningarna att optimera samt automatisera dem administrativa processerna för att i slutändan kunna lägga större fokus på själva kärnverksamheten.Studien syftar till att undersöka lämpliga affärssystem för mindre företag och även utreda tillvägagångssätten som finns för att välja och anskaffa ett affärssystem. På uppdrag av företaget Stockwine Group AB har vi fått möjligheten att undersöka ämnet på ett verkligt fall. En insikt som har uppkommit med studien är att det finns få allmänt erkända tillvägagångssätt vid anskaffning av affärssystem, istället använder sig leverantörer samt konsultföretag av egna metoder.
