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 report is the result of a master thesis at the Department of Mechanical Engineering, Division of Industrial and Economical Development, at Linköping University of Technology. The project was carried out on behalf of Fanerami AB, Mjölby and includes 20 weeks of full time schedule work.Cabinets with vertical mounted roller shutters all share the same problem, namely weight balancing. A roller shutter has an equilibrium area where the sum of the different forces acting on the shutter equals zero. As the shutter leaves that area it will pick up speed as it falls towards the bottom. When the shutter hits the bottom of the cabinet there is a potential risk of getting fingers caught and in this project a solution to prevent this from happening was to be presented.In this project, three concepts have been generated with the following different purposes:?In concept 1 the risk of getting any fingers caught when the shutter closes was to be eliminated in an efficient and inexpensive way.?In concept 2 the roller shutter had to be balanced at all time providing the possibility to keep the cabinet open in any position.?The last and most challenging task was to create a remote controlled TV cabinet.

The focus of this thesis is primarily in electronic construction and describes the design process for a microcontroller circuit board from concept development to prototyping. The client develops test fixtures for automated testing of products within the electronics industry and needs a new controller circuit for the test fixtures that can handle controls and basic testing. An investigation into the needs of such a system is conducted and a prototype printed circuit board assembly is manufactured.The prototype is developed with focus on protection against electrostatic discharges and overvoltage. Among the functions that are included are voltage measurements, communication interfaces and control of input and output currents. Firmware for the prototype is developed and configured to communicate with a PC through USB interface for control and collecting of measurements..

Detta är en rapport över mitt examensarbete som utfördes för Motion Control AB i Västerås.Uppgiften bestod i att ta fram en prototyp för en handhållen ljudlokalisator för döva. Projektet harinneburit arbete med allt från marknadsundersökningar till lödning. Projektet innehåller såvälanalog elektronik som programmering.Mycket tid gick åt till själva förarbetet, kanske lite väl mycket då det kändes som halva tiden gick åtinnan jag kunde komma igång och arbeta. Jag lyckades få fram en prototyp där allt fungeradeförutom mikrofonerna, de visade sig vara för känsliga för att löda för hand. Dock så har projektetvarit mycket lärorikt och intressant..

Quadrotor UAVs are self-stabilizing, autonomous flying machines that has recently become more popular than ever. Unmanned Aerial Vehicles have their roots in the military, where they were developed for use in reconnaissance and combat. During the last few years, advances in the fields of electronic sensors, electric motors and microcontrollers have enabled smaller designs and autonomic flight control even for private use. The quadrotor, which is the particular kind of UAV we are looking closer at in this paper, has 4 rotors in an X-like formation. This configuration has many advantages such as good lift capacity, non-complex mechanical structure and serviceability.In this project we aquired a current overview of the domain and determine whether it is possible to construct a quadrotor UAV designed for use in a WISENET sensor network on a low budget and short time schedule.Based on existing community project AeroQuad, a quadrotor is constructed with a budget of about 500 euro.

In the electronic industrials, power control of AC motors is commonly used. For example power control of a washing machine motor, a vacuum cleaner motor or a coffee machine motor. The company Rejlers Ingenjörer AB has many projects where power control of AC motors is included. A prototype card for this task can save time and money for the company in the future and this is the reason for this thesis.The motors are power controlled by a TRIAC and control of the trigging pulses to the TRIAC. This card is modularly built and can easily be adapted for future projects where the power control of AC motors are included.The prototype card can be used as a subsystem in a larger electronics projects or as it is in lab environment for testing and evaluating new motors..

I have, with a point of departure in two case studies; the artist, curator and scientist Andreas Gedin and Maria Lind, curator and director of Tensta konsthall, contextualized with a couple of respondents; the freelance curator, writer and editor Power Ekroth and the freelance curator and artist Carl Michael von Hausswolff, conducted a field analysis on curatorial and artistic practices. I have applied key concepts in order to conduct the analysis.Furthermore, the case studies and the respondents have been placed in a contemporary artworld. These components have been related to a contemporary historical segment of the artworld. This in turn, has been related to older, international cicumstances of change and various conditions in the two subfields. I have suggested certain a proximity in the artistic and curatorial practices.

With the development of the Internet, illegal copying of electronic documents has become a growing problem. There is an increasing need of prevention in the field of pirate copying. One method is to mark the document by changing some of the words to synonyms. In this way it is possible to construct legal copies which do not differ in content but still are unique. Since the copies of the documents are unique, it is possible to trace the owner of a document and accordingly call him or her to account for pirate copying if several exactly similar copies are reaching the market.

Internationally most Internet trade related payments are performed with the use of a credit card based payment system on the Internet. Payment against invoice is still most common when trading over the Internet in Sweden. The security development, comfort and timesaving indicate that credit card based payment systems on the Internet soon will have a breakthrough in Sweden as well. The Swedish legislation concerning payment is neither especially extensive nor suited to electronic payments but to payments performed with notes and coins. When the legal effects, of a payment performed with a credit card based payment system on the Internet, set in is not fixed.

TV and radio services have always been distributed over analogue broadcasting networks and been received on a TV -set or a radio receiver. Today this situation is changing due to digitalization and convergence between broadcasting, telecommunications and data communications. Other terminals, such as a PC, can also receive TV and radio services. Digital TV and radio can offer additional services such as e-commerce, electronic program guides and content synchronized to the TV and radio shows. If these services are to be received by several receiving terminals with different properties, the services must be adapted to the terminals.

The environmental requirements and laws on combustion engine emissions are very tough today andthey will become even more stringent in the future. To achieve these requirements there are highdemands on the control systems for these engines. An improved precision in the measurement of anengine's speed and position gives the electronic control system an even better timing when it comes tofuel injection and ignition. This makes the engine more fuel efficient, reducing the emissions. This thesisis part of a collaborative project between Hoerbiger Control Systems and subsidiaries.

Stereotyper är starkt förenklade, känslomässigt laddade mentala representationer om personer som tillhör en viss grupp, som i sin tur kan generera fördomar. Studien undersökte huruvida svenskar och invandrare bedöms olika vid samma brottstyp. Det predicerades att invandrare skulle bedömas mer negativt, bedömas vara mer sannolika att återfalla i brott, samt rekommenderas längre straff än svenskar. Dessutom skulle män bedöma gärningsmännen mer positivt. 85 deltagare bedömde en av fyra varianter av en brottsbeskrivning där förövarens etnicitet samt brottstyp manipulerades.

Examensarbetet har gått ut på att uppgradera ett styrsystem och en operatörspanel för en centrifug i en kemisk industri. Projektets syfte är att centrifugen ska köras på ett mer automatiskt sätt med ett nyare system som har större tillgång till reservdelar.          Centrifugens äldre styrsystem från Siemens har bytts ut mot ett nytt Siemenssystem och den tidigare operatörspanelen från Siemens har bytts ut mot Beijer Electronic E1070 operatörspanel. Styrsystemet programmerades sedan i Siemens Simatic Step7 och operatörspanelen programmerades i Beijer Electronics E-designer.                Efter att programmeringen var klar testades kommunikationen mellan styrsystemet och operatörspanelen innan inkopplingen av det övriga systemet skedde.
