This degree project is an investigation of solar cells and their ability to deliver electric power as well as reducing the need for cooling. The main object of interest is a BASE-X shelter. The shelter is purchased by the Swedish Defence Materiel Administration, FMV to be used for command and camp in the new force called Nordic Battlegroup, NBG. The demand on the equipment is firstly that it should have a small weight to be easy to transport and handle and secondly to be easy to bring up fast. Therefore the choice of solar cell technology fell on thin film cells.

I Kalmar kommun finns en datormodell över hela kommunens vattenledningsnät. Detta examensarbete gick ut på att med datormodellen samt med tryck- och flödesmätningar ge svar på ledningarnas kondition vad gäller råhetstal och eventuella dimensionsminskningar, samt framförallt läckagepotentialen i ledningarna. Målet var att få en så pass välkalibrerad modell att en avvikelse i tryck mellan det uppmätta och det beräknade värdet kunde detektera en flödesförändring, vilket i sin tur kunde bero på ett läckage. Modellen ska kunna användas som ett direkt läckageanalysinstrument. Beräkningsmetodiken som använts är State Estimation, som baseras på minsta kvadratmetoden.

In a time of economic turmoil and financial crisis profitability matters rise higher and higher on company agendas. Many companies are pressured to find profitability to avoid layoffs or even bankruptcy. Profitability essentially depends on the margin on the product or service sold and the costs associated with selling these products or services and hence these areas are of vital importance if companies are to improve profitability. Previous research has focused, for the most part, on product profitability while customer profitability has received less attention. This study is based on a case study of a Swedish publishing house and aims to investigate how the company?s Cost-to-Serve varies between its distribution channels.

The basis of road investments is to minimize the transportation cost. The forest industry wants roundwood to be available during the whole year. One way of determine which road to invest in is to do a cost/benefit calculation. SCA Forest lacks a uniform approach to determine the utility of a road investment. The goal of this report is to describe how the organization works today and find areas of improvement. The data collection was done through interviews.

A Swedish electronics company wants to make the cooling of one of their electronic components more efficient. They propose that a retrofit liquid cooler is the way to achieve this goal. The current air cooling has high energy cost due to the high amount of power needed to power fans and heat exchangers. Using high volumes of air for cooling also leads to noise pollution. The conversion from air to liquid cooling would possibly make the operation of the electronics more cost efficient and less noisy.The purpose of this project is to theoretically evaluate different concepts of drawing the heat generated by the electronic component in to a fluid, using numerical calculations in Matlab and FEM simulations in ANSYS.

This Master?s Thesis aims to investigate and assess the methods used to decrease the discharge ofmetals, primarily copper, from the water purification plant at Assa Industries plating factory inEskilstuna.Literature studies of the purification methods precipitation, ion exchange, evaporation, reverseosmosis and electrolysis has been done to appraise the adequacy of the technique. Thesetechniques are commonly used for purification of industrial waste water.Assa has four plating lines: the Trumline, the big Zinkline, the new Zinkline and the Decorativeline. The new Zinkline is the most modern of the four lines and purification is done byrecirculation over an ion exchange unit. The demand for fresh water is thereby heavily reduced.The Trumline, the big Zinkline and the Decorative line all use older techniques.

AbstractThe assignment were assigned by Camatec Industriteknik AB. Camatec is a Karlstadlocated consulting company, they make everything from pilot studies to complete projects in mechanical design and calculation. They even have their own patented product, Camcoil. It is a winder for steel strips and is used for example with hardening of the steel strip. The assignment has been to solve the problems encountered by some customers within this product.

In modern industrial robots the components in the transmission contain nonlinearities. These nonlinearities need to be to estimated either for better control or to use the parameters for diagnosis of the system. There is a lot of work done within system identification and mainly within the field of iterative parameter estimation.This thesis considers recursive grey-box identification for a nonlinear model of the transmission in an industrial robot. The nonlinearities that are identified are friction, spring stiffnes, hysteresis and backlash. These nonlinearities are a part of the models that are presented in this thesis.

The purpose of this study was to examine interpersonal problems and its relationship to the working alliance in psychotherapy. To examine this, data was used from Umeå and Lund University psychology practice client database, which clients responded to by using the self-assessment scales Inventory of Interpersonal Problems Circumplex Scales and the Working Alliance Inventory. The sample consisted of 201 participants that answered the questionnaires both before and after psychotherapy. A second sample consisted of 93 clients who specifically sought help for interpersonal problems. Results showed that the level of interpersonal problems before and after psychotherapy changes.

This essay deals with the topic options costs and whether such costs would arise for smaller companies now when they have the opportunity to choose not to have an auditor. Small companies are defined as companies that fulfill at least two of the following three criteria?s: less than 1,5 million SEK in balance sheet, less than three employees and turnover less than 3 million SEK. The decision regarding internal revision does not only affect the company itself but also other parties such as the taxation authority, banks and others that can be influenced by the decision. This essays main focus is on the influenced parties, especially the taxation authority and the banks as these have been highlighted in debates in media and because the small companies themselves may have difficulties to foresee the consequences of the new changes. The opinions from accounting companies will be considered in the essay as they can be considered as experts regarding the different aspect within this area.

The purpose of this report is to examine various roof structures that can operate in a warehouse with large spans. The building that is examined in the report is currently under construction, and the roof construction has already been selected. The selected roof system will therefore be compared with some other structures and materials that have been possible. The report will evaluate three different frame materials, two insulating barriers and two overlaying materials. Another important part in major construction projects is the roof safety.

Samhällets resurser är begränsade och en prioritering av olika verksamheter nödvändig. Cost-utility-analysen är en typ av ekonomisk utvärdering som syftar till att utgöra en del av beslutsunderlaget vid prioriteringsbeslut. Uppsatsen gör en cost-utitlity-analys av den ickefarmokologiska hypertonibehandling som genomförts vid Vindelns hälsocenter på individer där traditionell behandling inte haft önskvärd effekt på blodtrycket. Det sänkta blodtryck deltagarna på internatet erhöll minskar riskerna att drabbas av hjärtinfarkt eller stroke. Cost-utitlity-analysen inkluderar både till behandlingen relaterade kostnader och inbesparingar samt framtida till behandlingen orelaterade kostnader, som en följd av att individiden lever längre när riskerna minskar.

During the autumn 2009, a 15 hp degree project was accomplished. The objective of the study was to describe different equipment alternatives, suitable for fresh market apple harvest. A field study was conducted during the harvest period to evaluate the efficiency (kg / person/ hour), using the different equipment. Four different systems are described in the study; Pick-ing-bag, Picking-train, Pluk-O-Trak and the Conveyor Harvester. The information about the systems is based on interviews with growers together with previous studies.
