Test och verifiering av en ny inkapslingsmetod för SiC BJT och MOSFET

The use of silicon carbide (SiC) as a base material in power electronics has manyadvantages, including high breakdown voltage and excellent temperature endurance.However, the packaging of such electronics presents major challenges and there is aneed for packaging that can operate in higher temperature. The purpose of this thesishas been to develop a test method and verify the functionality of SiC powertransistors prototypes with a new packaging Technique developed by Swerea IVF AB.It includes setting up an electrical test-bed for power and high temperature cyclingand analysis of the results. Even though test confirmed functionality after thepackaging process, (at room temperature) the performance seemed to have been reduced. This could be a result of the measurement setup and the packaging process.In higher temperature the transistors failed to operate longer than a couple ofminutes which showed the weaknesses in the design and the challenges with this typeof packaging..

Utveckling och tillämpning av det muskelstyrda datorspelet EMG Track Game.

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.

Kommunikationsverktyget intranät

AbstractThis report discusses how the intranet as a communication tool can bedeveloped to become a daily work tool. An intranet can help the organization to get information out to the employees fast, and the employees can choose when they want to take part of the information. This report also discusses how the functions and the presented information can be developed to be even better. The proposals has been developed out from information gathered from a survey,the people who has answered the survey has been given their point of view of the intranet, and also proposals for improvements, which we have implemented in to our theory part. There is no company or organization that uses the exact same intranet solution.

Undersökning av modulationsscheman för existerande bredbandsteknologier

In this thesis some different modulation schemes for xDSL-Techniques are compared. The investigated Techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several broadband Techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.

Bära lin - ett utforskande möte mellan tråd och visa

Simplicity, intimacy, freedom and one single threadcharacterize the knitting Technique.In my project, I have studied ways of creating three-dimensional shape and structure using single threads and various knitting Techniques. I applied my ideas in a collaboration with the singer Sofia Karlsson. The focus has been to design a portable object that can be used in pictures for the cover and promotion of her upcoming album.The material I studied, processed and used in creating the three-part object was linen. In the center stands a collar, that changes expression depending on how it is worn and which side is turned towards the outside. The collar interacts with a cylinder for her hands and a hairnet.
