Jämtkraft AB which is a power production company in Sweden has bought two newhydro power units to their station in Hissmofors. The two new generators are using aconcept with sliding stator feet to handle the thermal expansion.The concept with sliding stator feet on hydro electric generators has not beenworking satisfactory on many hydro power stations in Sweden and has caused a lot ofcosts due to long downtimes.The new station in Hissmofors is very important for Jämtkraft AB, and therefore theywant to know how to make sure that the sliding stator feet are working as theyshould. According to theories and a simplified model of the generator the stator feetdisplacement should be around 1 -1,6 mm.The generators are delivered with a surveillance system that will measure thedisplacement of the sliding stator feet. The signal from the system isn?t accessible forJämtkraft AB but it will alarm when the sliding stator feet are malfunctioning.To secure the function of the sliding feet a logger for the surveillance system or adifferent measurement system must be used; if both systems are used Jämtkraft cansecure the function of the surveillance system..

The purpose with this report is to examine how the implemented energy efficiency measures on Bokelundskolan in Växjö have had impact on the energy use. The measures which have been implemented are, new ventilation system, new heating system, optimized adjustment of the heating system, new windows with U-value 1.2 and lower window height, insulation under windows and in the crawl space. The school's energy use before and after rebuilding has been calculated with the calculation program, Vip-Energy 1.5.5.Calculations of energy use for the school with windows on U-value, 0.9 and 0.7 have also been done. The replacement of windows has been studied from a cost perspective. The conclusion is that the exchange of heat and ventilation system was the biggest contributor to reduced energy use on Bokelundskolan.

We have performed a case study on Acne Jeans, a creative Swedish fashion company, which initiated a cooperation with the Swedish venture capital firm Öresund. The aim of our paper was to examine what motivates a venture capital firm to transform the management control system of a creative company, into a more formal system of control. Main results: Öresund did not have an excessive impact on the management control system of Acne Jeans, due to three main reasons. First of all, Acne Jeans had a satisfactory management control system prior to the cooperation. Furthermore, the relationship between the two parties was characterized by mutual trust.

Svenska Kraftnät is (together with the other transmission system operators of the Nordic power system) responsible for keeping balance between the generated and demanded power in the Nordic power system. Spontaneous load variations and system disturbances, however, lead to power imbalance followed by frequency variations. The frequency deviations can be limited to an acceptable level by the spinning reserve, mainly by hydro power control. But there are also other system properties which have a great influence on the frequency and system stability. The frequency and voltage dependence of the loads have a direct influence on the power balance.

Inköpsfunktioner inom kommunal verksamhet har under de senaste åren lidit av ineffektivitet i form av höga kostnader och felaktig resursfördelning. Denna ogynnsamma situation har lett till reformer så som ökad centralisering. Syftet med denna studie är att, med utgångspunkt i en svensk kommun, skapa förståelse för hur effektiviteten påverkas av ovan nämnda reform. Mer specifikt hur den adaptiva respektive allokativa effektiviteten påverkas. Detta genom att skapa förståelse för aktörernas förändringsvilja och deras förutsättningar inför centralisering samt att med utgångspunkt i organisationens lagefterlevnad och resursfördelning, och hur dessa faktorer har påverkats i och med centraliseringen, göra tolkningar om effektiviteten.

The purpose of this project was to further develop and complete a quadcopter that had been built in an earlier course at KTH, so that it could be used for demonstration and education at the school. The quadcopter was at the beginning of the project completed when it came to hardware, and there was some software functionality implemented but no system for automatic stabilization. The main goal of the project was to implement such a system, and to combine it with the previous functionality to make the quadcopter operable and able to fly. To create a functioning and stable ground multiple basic software features has been implemented, and on top of that additional software to improve the safety, stability and functionality. The most important part is the control system that is responsible for converting sensor and control signals to suitable motor values.

Återanvändning av information utgår ifrån att bryta ner den informationen man planerar att återanvända i moduler som struktureras upp. Dessa moduler kan sedan användas för att bygga upp ny information till nya produkter. Genom att ha en organisation där avdelningarna arbetar nära varandra har man en möjlighet att förbättra återanvändningen och skapa ett system med både information och kunskapsutbyte. Genom planering kan man maximera möjligheterna och undvika flertalet hinder.Informationen skall vara välstrukturerad med en vald målgrupp för att lättare kunna återanvändas. Produkten har en betydande roll i återanvändning där enklare produkter är av mindre behov av strukturering än komplexa.

Hemlösa personer tillhör en utsatt grupp i samhället med ofta komplexa sociala ochhälsomässiga problem. Deras förutsättningar leder till att de betydligt oftare drabbas avfysiska sjukdomar, psykiska besvär och missbruk än den övriga befolkningen. På grund av dehemlösa personernas behov av hälso- och sjukvård kommer vårdpersonal ofta i kontakt meddem. Uppsatsen beskriver mötet mellan hemlösa personer och vårdpersonal. Enlitteraturstudie genomfördes där 12 artiklar analyserades utifrån Burnards modell förinnehållsanalys.

In Stockholm, Johanneshov the Slaughterhouse area (Slakthusområdet) can be found. A number of companies have gathered there providing the Stockholmers with meat products. This area has a great need for cooling to supply large cold storages. To facilitate this, a central cooling system has been built, supplying the area with effective and safe cooling.The aim of this master thesis study is to give hints to energy efficient and reliable changes that can be put in place at a low marginal cost depending on the future activities in the area. The suggested changes will be presented to the company Bravida (managing the system), which also desires a deeper understanding of the energy flows through the central cooling system.Firstly visiting the site with proper guidance, we have then tried to understand the function of the system including which machines and media that are used.

The aim of this study is to examine the possibilities to use gamification to reach thepolitical goals for the transportation system in the Stockholm region. The study has aninterdisciplinary approach and is based around two main building blocks: gamificationand the transportation system in the Stockholm region. The first part examinesgamification. This includes contemporary use, debate, academic definition and aninvestigation of how gamified applications should be developed. One of the mainfindings is a suggestion that gamification should be seen as a process rather that a setof predefined game mechanics that can be applied to any activity.

The purpose of this study was to create a picture of Södra´s round wood transporters usage, and positive or negative experiences of the KOLA-system. The KOLA-system, owned and managed by SDC, is a program for handling timber orders and displaying their locations on digital maps. The study was conducted as a twenty-three question internet-based survey. Of those asked to complete the survey, 57 percent chose to answer the questions. The results of the study indicated that several of the transporters found the system quite good and used it to a large extent. The system also had many deficiencies however, and there was clear potential for further increasing the usage of the system.

The purpose with this study is to compare different systems of grain storage from a financial point of view. Grain that is supposed to be fed to laying hens. The systems that were compared were different airtight storage of grain and a system of conventional storage. To make this case study I choose to compare four different systems. In the case study there was one system with bin drying of the grain, two systems with airtight storage of the grain and one system where you buy dried grain during the season. I made several of capital investment appraisal where I found the cost of each system, then I took the cost and divided it with the total grain use and calculated the cost for each kilogram of grain, and also the cost of the feed. Then I compared the cost from my case study with the cost of buying feed. All the systems except for one, gave a lower cost for the hen feed than buying feed from a dealer The best system, witch were bin drying lower the cost with about 80 000:- SEK.
