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.

This essay focuses on the technical systems and functions behind how a Roman bath operated. I will present a general view by going through each part of the waters path through the bath one by one. Since there is no such thing as a standardised Roman bath I will, under each headline, present the sub subject with a presentation of the workings and then exemplifying through archaeological findings and ancient literary sources.This essay is therefore meant to present a thorough and clear presentation of the technical aspects of a roman bath. The aim is to give the reader an understanding of how a bathhouse worked in general and why. To this I want to present problems that the Romans were faced with and how they solved them..

The aim of this thesis is to describe the customer?s attitudes toward the contracting for availability, i.e., which factors are from the customer?s perspective necessary for the fulfilment of a supplier-customer agreement? Furthermore, the objective is to describe and analyse a supplier-customer relation in the Defence Industrial sphere.The present study has been carried out as a case study using an abductive approach. The thesis is based on a practical problem, i.e. which factors will be important to the customer when a contractor in the Defence Industry wants to increase its commitment of service, and how will their relationship change? The thesis is above all focused on generating knowledge that can lead to rapid and concrete measures and that can be used in the analysis of an increased industrial commitment but also as a case study of a problem of a more general nature in the Defence Industry.

The gas turbines in the Swedish secondary reserve are reaching the end of their technical lifetime, hence alternative solutions need to be considered. One of the solutions thought to have the greatest potential is the use of so called consumptionreduction. By entering contracts with large consumers, agreements are made to reduce consumption in the event of major disturbances in the power system and thus being used as a secondary reserve. This thesis investigates the feasibility of consumption reduction as part of the secondary reserve. This has been achieved by developing a requirement specification for the disturbance reserve and by studying the technical and economic potential for consumption reduction among a range of consumers.The technical potential for consumption reduction that fulfils the requirements for participating in the secondary reserve are on average 750 MW in SE 3 and 98 MW in SE 4.

Wavecraft AB develops medical equipment for heating of organic synthesises. The heating is done with microwaves, which improves the process in both speed and accuracy compared to the more traditional methods where heating elements are used. This report discusses the developement of an automatic lid mechanism for one of Wavecraft's product prototypes. The company assumes that the final product will be integrated by customers into fully automated systems, and the upgrade from a manually to an automatically controlled lid is therefore an important step in the product's developement process.The first stage och the project was an idea generation process. The ideas generated here were organized into five different concepts of which the best one was selected through the use of a concept matrix.

Earlier studies of musculoskeletal problems with milkers working in milking parlour operators have shown that it is a physically demanding occupation. The extremities that are most exposed are neck, shoulders, hands and wrists. Those systems that have been studied in present cases are fishbone and some tandem barns. There have been changes in the working environment during the past ten years. The mechanisation has been developed for the better with automatically removers of the milking units and vertically adjustable floors in almost every daily milking barn. In other hand the milk production are more industrialised and more related to stress today.

I have chosen to work with drag hose system and try to find an alternative to spread manure with a usually tank system, see if you can make a profit and what advantage and disadvantage the system has. The purpose whith the project has been to try to make a system that can spread manure at better occasions than farmers do today and above everything make a financial addition. Today it is just a heavy work and takes a lot of time. I have counted on investment costs and carefully examined what equipment you need. I have not the technical details in my project, I have just tried to understand how it is to spread manure with drag hose system today. What is drag hose system? You put a hose in your manuretank, connect it to a pump that is driven by a traktor or stationary engine. You place a hose that reach the field were you are going to spread.

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.
