Regulatorer med styrsignalsbegränsning
This thesis studies the negative impact that control signal saturation may have on a controlled system. Different methods that are used to compensate for this problem are also studied and evaluated. Both sensitivity to disturbances and the effect the method has on the systems'ability to follow a reference signal will be examined. Stability will be discussed, but no conclusions whether the systems are stabilized or not can be drawn. Control signal saturation will lead to a slower behavior in general.
?Allt jag har är en dröm jag inte klarar? : Maskulinitet i Ken Rings och Håkan Hellströms musiktexter
Denna uppsats handlar om hur artisterna Håkan Hellström och Ken Ring konstruerar diskurser kring maskuliniteten i sina musiktexter. Utifrån poststrukturalistiskt influerad teori kring feminism och maskulinitet görs en komparativ närläsning som bildar en tematiskt uppbyggd studie. Utifrån det för artisterna gemensamma temat utanförskap visar studien att utanförskapet hos Ken Ring är relaterat till en känsla av maktlöshet. Denna kompenserar Ken genom att konstruera maskulina diskurser med ett överdrivet anspråk på det som den europeiska kulturen förknippar med maskulinitet och genus. Detta kan kontrasteras mot Håkan Hellström som i sitt utanförskap konstruerar maskulina diskurser där ?omanlighet? och ett kärleks- och sexualitetsbegrepp där ?jaget? blir könsmässigt tvetydligt, står i fokus.
Överföring av elektrisk signal och effekt med magnetisk induktion.
This report tested the possibility of using induction as a mean for transferring data and power so that it can be implemented as a communication medium between a terminal and measuring head mounted in a measuring frame. This would eliminate the need for the cable bunches that are used today. For testing, signal generators were used to generateFSK-signals and were transferred with the help of inductors to the oscilloscope for signal detection, this to see how the coils used in the tests behaved. Simulations of a PLL were performed to see how good it could handle FSK-demodulation. With the help of a PLL IC and the simulations a working FSK-demodulator could be assembled.
Konstruktion Signalgenerator
SAAB Aerotech division FGR in Arboga builds and develops equipment and components used in both military and civilian applications. To build a test system for a specific project that SAAB is responsible for requires a simple signal generator that can provide a pulse modulated signal. The need to buy a new advanced signal generator for example from Agilent is not as profitable as the instrument is expensive and contains features that SAAB does not require in their applications and test systems. That was the reason why SAAB offers two students a thesis where the goal is to construct a signal generator in accordance with what SAAB requests.This thesis contains several different phases. The first step was a meeting with our supervisor Mats Bergman and by reading the data sheets for components to be used in the project, with these information and specifications that we have received from SAAB we started to construct the signal generator.What we did during the construction work was to simulate and draw a schematic to be able to design the circuit board.

Knacksensorplacering på lastbilsmotor
This work is an experimental study where knock sensor placements are investigated using engine tests. The aim is to studythe quality of the signal from knock sensors and how the signal for engine control is affected at different sensor locations on Scanias, engine DC13. To find out at witch position on the engine youcan get a usable signal for engine control, the engine is running while the knock sensors with advanced measurement equipment is connected to the engine. Evaluation of signals from the knock sensors are made in the computer program Matlab. The program is producing a seriesof plots, from these plots it is visually possible to draw conclusions and find connections.
Kulturell inverkan pa? kunskapso?verfo?ring o?ver nationsgra?nser
I denna studie underso?ks vilken inverkan kulturskillnader har pa? kunskapso?verfo?ringsprocessen o?ver nationsgra?nser i mindre svenska fo?retag. Detta go?rs genom en fallstudie av det svenska elektronikfo?retaget CrossControl, som nyligen startat en fabrik i Malaysia. Efter att ha observerat att det finns viss problematik med att bli ett multinationellt fo?retag sa? sa?g vi ett behov av att underso?ka om na?gra av de ma?nga hinder som finns vad ga?ller kunskapso?verfo?ring kan kopplas till kulturella skillnader.
Utvärdering av grafisk utvecklingsmiljö för programmering av signalprocessor
This work aims to evaluate the possibility of using a graphical programming language to develop software for a digital signal processor. A fixed-point digital signal processor called Blackfin BF-537 is used for this. Instead of using conventional programming languages, like C or assembler, for software development the possibilities to use a graphical environment to fill the same purpose are examined. The development environment primarily used is NI LabVIEW, but also the use of Mathworks Matlab Simulink is investigated. A variety of programs consisting of various signal processing operations and utilities are developed using these development environments.
NATURMINNENS F?RVALTNING OCH SKYDD: Inventering i V?stra G?taland
Natural monuments are natural objects with special protection due to their high natural value or cultural significance. The natural value is determined by the occurrence of signal species found on and near the natural monument. The law surrounding natural monuments has evolved a lot since the first ones were declared, and today the title natural monument can be replaced with the title tree with high conservation value. The title has come later and can sometimes overlap natural monument. Some natural monuments lack the qualities required to be classified as a natural monument or a tree with high conservation value, but have a cultural importance.
Ultraljudsmätare för bubbelfälla
This bachelor thesis is about an ultrasonic sensor, implemented in a bubble chamber in Artis. The sensor consists of the piezoelectric sensor and an electronic control circuit. The control circuit consists of a programmable microprocessor, PIC18F2420 and a circuit, which sends the excitation signal to the piezoelectric sensor, and later receives the echo. This bachelor thesis consists also of a theoretical study, which examines different techniques of liquid level sensing in a chamber. The study discusses which factors are important in liquid level sensing and examine accepted methods.

ZigBee-teknikens möjligheter att trådlöst överföra EKG-signaler
In many clinical applications, it is desirable to transmit sensor information wireless. In earlier research, investigation transmit ECG signal using Bluetooth, was performed. However, when Bluetooth has some drawbacks it is of interest to investigate alternative methods, one such method is ZigBee. Bluetooth has higher data rate speed (1Mbps) than ZigBee (250kbps). However, Bluetooth consumes more power.
Radiolänk med GNU Radio
At the Department of Technology and Built environment at the University of Gävle there was an interest to study GNU Radio, which is an "open source radio project. The project is based on that most of the radio signal processing is made in an ordinary PC. The idea behind this degree project was that in a laptop there are several radio transmitters/receivers that takes space, generates heat and transmit in varied frequency band etcetera. All these radio transmitters/receivers could be replaced with a Software Defined Radio system. It means that one common, general radio hardware is used to different communications such as: WLAN, Bluetooth, GPRS, 3G etcetera. The waveform is generated in the software, which makes the system very flexible.
