Most of the goats in the world exist in the developing countries where they are important in the meat industry. In Europe, goats are mostly kept for milk production although the interest for meat is growing. Goats have a thin carcass with only small amounts of intramuscular fat, which gives a lean meat. This thin subcutaneous fat cover can cause cold shortening when chilling the carcass. By using electrical stimulation cold shortening can be prevented.

Detta examensarbete har utförts vid Duroc Engineering AB i Luleå. Duroc Engineering är Sveriges ledande företag inom laserförädling av metalliska ytor och levererar tjänster och produkter till framförallt gruv-, stål-, flyg- samt verkstadsindustrin. Rostervagnar transporterar kulor som används vid sintringen i Malmberget vid LKAB:s kulsinterverk. Genom att vagnarna passerar genom olika värmezoner sintras kulorna och vagnarna töms därefter för att hämta upp nya kulor. Detta pågår dygnet runt, året om, vilket medför stort slitage på vagnshjulen.

Electromyography (EMG) is a technique that measures muscle activity, whichmeans detecting the electrical signals that travel through the muscle in connectionwith muscle contraction. This project deals with how EMG can be used tocontrol a computer game.The project is centered around the game 'EMG Track Game' which has beenconstructed as part of this work. 'EMG Track Game' is controlled by twoelectrodes fastened on the player. These are attached to two selected musclesand control the motion in one direction each, one up and the other one down.The game is constructed in the purpose of being used in several elds of application.Among these are as entertainment, training equipment and a tool inresearch related to EMG and muscles.To highlight a possible application a study concerning muscle control has beenconducted. It answers the question of whether players score better with theirdominant arm in comparison with their non-dominant one.

Energy consumption is at present a major political issue, and numerous projects that comprise many nations are currently in process to increase energy efficiency and bring down energy dependency. As a member state of the EU, Sweden now faces the challenge of implementing substantial energy-saving measures until the year 2016. One of these measures is the project ?Green Islands? financed by the EU that intend on creating sustainable islands in areas around the Baltic Sea. The Archipelago Foundation leads the project that concerns the Stockholm archipelago, where focus has been placed upon decreasing energy usage in businesses and services on Utö among other islands.

Nano materials can today be found in a wide range of consumer products and the number of new products on the market is expected to inrease. In the shadow of hope for nano materilas potential in various applications, low awareness of its health and environmental risks is hiding. Furthermore, the knowledge about people´s risk perception of nano materials is limited. Parallel to the situation described above, the scholls meet the challenge of incrasing the scientific literacy. To achieve this goal, skills in argumentation in science studies has been emphasized and the concept of socio-scientific issues has been emerged.

The goal is to identify weak points in the chillchain and to se how wrong temperatures affect the flowers. The results can be a help to secure the chillchain.Method:The work started with a problem; map the distribution of cut flowers with focus on temperature losses. Data was collected on the basis of this problem, then analysed, and finally conclusions were drawn.Conclusions:The affect handling and distribution has on a cut flower is very complex.

The division of Engineering Materials at Linköping University, department of Management and Engineering, conducted a research project concerning Fatigue life of thermal barrier coatings during 2009. During this project equipment to provoke these fatigue failure by rapidly heating and cooling test subjects in cycles, was ordered.Design and manufacturing of the equipment was handled internally at LIU.The equipment was built using a furnace that is lowered and raised over the table where the test subject is placed. To keep the temperature of the furnace a lid slides in place to close the downward facing opening of the furnace when it is in the raised position. On this door there is nozzle that is used to cooling of the test subject by air.To make sure that the equipment can work independently you need an automation controller that can evaluate if movement can occur without danger of collisions. The control system also needs to monitor that all elements are performed according to plan.This degree project is based on a modular system from OPTO 22 and includes the configuration of a PLC that will be supplied with logic and a user interface.The degree project resulted in a graphic interface in which a user can set desired values for different parameters and get information about current values for them.

Uppdraget som gavs av Brimer VA Produktion AB i Osby var att ?föra fram deras nya vattenledningssystem i ljuset?, göra en FEM-beräkning på en detalj i systemet och ta fram en ekonomisk samt teknisk jämförelse mot det traditionella vattenledningssystemet. Bästa lösningen på uppgiften var att visualisera vattenledningssystemet med hjälp av animerade filmer. Detta med tanke på att visualisering har ingått till stor del i utbildningen Virtuell Produktutveckling & Design..

Because of increasing demand of power on Malmbanan the capacity of the existing wires which supply the trains must be increased. This increases the stress on the existing poles and for this reason the system for supplying the loads along the railway is to be removed from the poles and be replaced by some other system. This thesis is a study on a two-level low voltage (1 kV and 0.4 kV) electrical system with the aim to investigate if it can be an alternative to the system used today taking into account the voltages, fault currents and costs.In this thesis the following tasks have been performed:? Gathering of data? Description of basic theory? Loadow and fault current calculations of the system with MATLAB? Life Cycle Cost estimate of the system? Analysis and conclusions from the resultsThe results show that the new system can be an alternative to replace today's system. The simulations and calculations show that the voltage drop is at an acceptable level and that the fault currents are large enough to supply a safe disconnection if a fault occurs at the far end of the system..

The electric vehicle market has potential to contribute to Sweden?s national goal to have a fossil fuel independent transport sector by 2030. However, the market answers to a lot of challenges making it difficult for the market to fully reach its potential. The volume of electric vehicles has seen a steady increase during the last year (2012), although many of these vehicles are mostly for PR purposes or bought by the public sector that wants to lead by example. Still, barriers in the form of high purchase costs, an anxiety for the limited battery capacity and the lack of standardisation are some of the problems that the market is struggling to solve.

The dissertation deals with an account of actual problem, which can arise within EMC and power quality. The cause of power interruption and what can be done to minimise the power interruption is discussed. It also includes a definition of planning levels and which factors one needs to have control over to carry out a possible planning strategy and how the local distributions net could be more secure. The electrical net could be secure but no system can be free from interruption.The dissertation examines two distribution transformers: GLA40T1 (Glansås) and T399 in Tranås Energy which don?t have regulators.
