This thesis is the result of the investigation and solution of a mechanicalproblem regarding flywheel malfunctions. A flywheel is, in short, a devicethat relies on a rotating object?s moment of inertia to store energy overshort time spans. This project is part of the development of a fourthflywheel prototype at the division for electricity at Uppsala university,which uses magnetic levitation to keep a hollow cylinder rotating at veryhigh speeds inside a vacuum chamber. Should the magnets fail however, orsome other error occur that leads to an uncontrolled state of rotation, thecylinder needs to be stabilized mechanically by a device usually referredto as ?back-up bearing?.

Background theories ? these intend to capture the problematic nature of the transforming telecom industry, examples of such theories are; value chain theories and ecosystem theory.

This thesis is ordered by Peab Sweden AB Regional Jönköping and concerns of warranty inspections.The intention is to work out a basis, which show the most common complaints is the warranty inspections, and make a small analysis on what causes them to be. The report also presents possible solutions to prevent the occurrence of defects. It also covers the issue of how the client looks at Peabs way to overcome the objections of warranty inspections. The report has the following issues:?What are the most common errors observed during the warranty inspection??What are the causes of complaints??What can be done to reduce the number of complaints??How the customer thinks that the complaints be addressed?Twenty-five Guarantee survey records from the projects Peab has done in recent years has been the starting point for the investigation.

It has become more common for organization to operate a lot of projects at the same time. These projects affect each other, either in way of resources or technical. Projects in a multi-project environment depend and affect each other, and in most cases they rival about resources, decision-makings and priority. To lead a project portfolio with several projects is a major challenge. The most common problems that occur are vague objective, unclear working conditions, resource shortage and problems of priority.

Svenska Aerogel AB has developed the material Quartzene® which is of the typeprecipitated silica and contains calcium - magnesium silicate ((Ca, Mg) SiO3). Thematerial is used for molecular filtration of contaminated air. Qartzene?, which is inpellet form, is porous and has a high internal surface which is a requirement for themolecular filtration. With the use of various impregnations, filtration can affect thedesired outcome.

The project, Flexible Snowboard System, has been carried out by the project group independently and is a module developed for snowboarders, ski rentals and ski schools. The problems of today?s solutions are that they cause the user an inconvenient standing position when riding the ski lift or skating the transportation slope, also mounting, adjustments and disassembling of the bindings are time consuming and brings undesired wear to the screws and screw holes. In addition any adjustments require that the user steps out of the bindings and have tools at hand. Flexible Snowboard System is a universal module which means that it can be assembled with all of today?s snowboards and bindings.

The purpose of this study is to highlight the second home sector in Sweden and Denmark, in a comparative study of regulations for the second home market, and residence requirement. Two attractive second home island destinations is being compared in Ven, Landskrona and Gudhjem, Bornholm. The study addresses issues such as the local effects of a regulation of the second home market get at a local level, and the effects generated by deregulation, as well as local people's opinions about second home regulation in a popular second home area in southern Sweden. This has been examined using a mix between qualitative method and quantitative methods, and the study is based on six semi-structured interviews from informants from Ven, Bornholm, and Gudhjem which has been analyzed throughout a thematic analysis. In addition to the interviews, diagrams from the Central Bureau of Statistics of Sweden and Statistics Denmark, and various real estate websites, and a field observation from Ven and Gudhjem will be presented.The result shows that show that the discussion on residence requirement has been going on for a long time in Sweden and Ven, but the local organizations found more disadvantages than advantages and are now looking in to other solutions, while other locals believes that there are more advantages with a residence requirement. In Denmark it?s revealed that there is recently started discussion between municipal decision-makers and local organizations about the regulations, and if it should be abolished or not.

This paper presents the result of a master thesis project at 30 Hp, master of industrial engineering at Luleå University of Technology. The project was performed during 20 weeks, spring 2014, in collaboration with ABB Control Products in Västerås. The aim of the project was to evaluate two half-automated assembly lines for a new generation of contactors, the NAFC assembly lines (New AF Conductor). The aim and purpose of the project was achieved by answering the following questions:? How are the ergonomic working conditions at the NAFC assembly lines during spring 2014?? Which areas at NAFC assembly lines can be improved for the work environment?? How can the ergonomic work conditions improve at the NAFC assembly lines?Literature reviews were performed from earlier research papers and articles of the ergonomic, musculoskeletal and work environment subject, from where a number of chosen methods and tools were used to perform the ergonomic evaluation.

AbstractThe future of ethanol is depending on good solutions for the production. ENA energy power plant produces electrical power and district heating by heating biofuel. By building an integrated bioenergy plant surplus steam could be used to produce ethanol as fuel to vehicle.This would mean that ethanol is produced renewable energy and the energy for the process derives from the surplus of power.  ENA energy, MDH (the University of Mälardalen) and the energy authority has initiated a research project were different bioenergy combinations integrate with existing power plant.  As a part of the project which size an integrated factory should be to gain the best efficiency for the plant was investigated. Consideration will be taken to the cost of the production in order to be competitive to the price of imported ethanol.  Etanolens framtid vilar på bra lösningar för framställning.  I ENA energi kraftverk i Enköping produceras el och fjärrvärme genom eldning av biobränsle.  Genom att bygga ett integrerat bioenergikraftverk där skulle man kunna använda överskottsånga till att framställa etanol som fordonsbränsle.

Bakgrunden till studien var ett gemensamt intresse kring ungdomars identitetsutveckling. Då inga studier kring hur just hemmaplanslösningar kan bidra till en positiv identitet gått att finna, så blev det intressant att genomföra en studie kring detta. Studiens syfte är att utifrån ett personalperspektiv öka förståelsen för vilken innebörd arbetet med hemmaplanslösningar har då det gäller att ta tillvara och stärka ungdomars positiva identitetsprocesser. För att kunna besvara detta syfte har frågeställningar utvecklats som först handlar om hur en personalgrupp beskriver att identitetsskapande sker i deras verksamhet och hur de sedan beskriver att hemmaplanslösningar kan bidra till att stärka dessa ungdomar i en positiv riktning. Studien har utgått ifrån ett socialkonstruktionistiskt perspektiv som har varit genomgående i hela uppsatsen.

By tradition, archival sciences has emerged in a context with defined information processes, with explicit information producers and custodians to which consumers make requests for the information. In this process, the archival science has developed methods and strategies to preserve authentic and reliable records and by that providing trustworthy information. In an online society, people are using the internet to get information for different purposes. Even though there is no legal obligation to guarantee the authenticity, it is of societal importance that the end users get trustworthy information. In this online context, open data is a trend that is growing fast over the world and it is interesting because its conditions raises many questions regarding authenticity.Since open data is free to reuse, link and combine with other information, and it is preferably in primary format it raises questions about how to maintain the integrity and identity of the information, which is the constituents of authenticity as it is used in this work.

Isaberg Rapid AB is a company that manufactures for instance staplers and glue guns. Headquarters and main factory is located in Hestra but there are also subsidiary companies in Denmark, Netherlands, France, Spain, China and England. There are also two filial factories in France and China.Today has the company no logistic guidelines committed and that leads to problems since the salesmen promise different things to the customers. This contributes too many different logistic solutions for Isaberg Rapid AB. The company has also noted problems with returns of goods.The purpose with this task is to standardize and compile logistic guidelines, usable to all Isaberg Rapid AB's small to midsize customers.

1 252 unaccompanied refugee children have disappeared in Sweden since 2007. These children have never been found. Nearly one unaccompanied refuge child disappears per day. This happens during the time they are within the Swedish authorities' responsibility. This thesis uses the framing theory of the mass media regarding the missing unaccompanied refugee children and what the mass media considers to be the cause of their disappearance, the moral aspects of the articles and the solutions to the problem.

The background for this degree thesis is a need to replace the existing seal used to protect equipment containing secret or sensitive equipment used by Swedish Defence. The target design should satisfy both the need for tamper evidence and reduce Life Cycle Cost. In developing a new design for a seal, additional benefits such as improved logistics support and indication of attack methods such as heat and solvents have been considered.The lack of guiding principles for end users of seals became evident during the interviews. Major concerns for the future are education of users, information about actions if a seal is broken and user liability.The design work was divided into several phases. A feasibility study was performed including investigation of theory of labels, materials and possible technologies.

Ever since ABB has begun diecasting their rotors instead of permanent mold casting it,variation in the quality of the cast has arisen. Diecasting is performed in three differentmachines, M1, M2, M3 with 400, 660 respectively 800 tons of die locking pressures.The aim of this thesis is to answer the following questions:What is the ?right? cast quality? How is the right quality achieved?For sizes 160-180 solutions will be proposed that consider eccentricity between thelaminate and the short circuit ring as well as elimination of the thin Al film that appearson the outer periphery of the rotors.Through considering the statistic material the most often diverging rotor type has beenidentified and one of the actual rotors has been sent to a laboratory to be analyzed inorder to establish the current defects. The result of the analysis shows that there areplenty of gas- and oxide-porosity.It has been proved that every time the dies temperature decreased below 120°C thecontent of gas porosity increased. It is due to rapid solidification of metal that flowsthrough the ?cold? laminate.It has confirmed that enhanced porosity in squirrel cage causes high impedance in therotors.
