Galoppträning och körning med två travare

The aim of this study was to evaluate whether gallop training, rather than regular drive training, is worthwhile for trotters race performance. Another aim of the study was to expand the author?s riding- and driving capacity, and get more practical experience on the impact of interval training on trotters. The sample population in the study was two trotters, one Standardbred, and one cold-blood. Given the small sample population, the results of the study is only indicative on the effects of gallop training on trotters, and not conclusive.

Reglering av veka strukturer med multipla sensorer

In this master thesis, control algoritms using arm side sensors are investigated for an industrial robot. The sensors can be position encoders placed after the gearbox and accelerometers on the robot arms. Control strategies are discussed and evaluated for different models of the robot, after which chosen strategies are applied to a realistic model. Control algoritms using arm side sensors (LQ, dual-loop and PD-PID) are compared to a PID-controller that only uses measurements of motor position for feedback control. The comparison are done with respect to disturbance rejection, oscillation damping, robustness and tracking performance of a reference trajectory.

PWM Effekt Audioförstärkare

The purpose with the report is to show that it is possible to design a class-D amplifier, using a programmable FPGA mounted on a developing card from Xess and a H-bridge. The FPGA was programmed in VHDL which is the language the software from Xilinx use to implement a logical function into the FPGA The logical function corresponds to a modeling of the music signal and the modeling can be described as a comparator which compare the music signal with a triangle wave and as a out signal produce a pulse width modulated (PWM) signal. The report is also a review and evaluating of two different modulating technologies, AD- modeling and BD-modeling. A detailed part about how the H-bridge was designed and how it works. The result of this project is a working audio amplifier to a significant lower price than the products in todays market..

Modellering av signalbehandlingen i ett cochleaimplantat och utvärdering av modellen.

Ett program som simulerar signalbehandlingen i ett cochleaimplantat med signalbehandlingsstrategin ACE (Advanced Combined Encoder) har konstruerats. Programmets främsta syfte är att i förväg prova ut inställningar i ett cochleaimplantat och genom detta försöka förutsäga olika användares individuella inställningar. Programmet har validerats med utsignaler bearbetade av Cochlear Limited i deras egenkonstruerade Matlab-modul för forskning inom cochleaimplantat, NMT (Nucleus Matlab Toolbox). Samma insignal som använts av Cochlear Limited har processats av programmet och utsignalerna från detta jämfördes med utsignalerna från NMT. De bägge utsignalerna, producerade med samma inställningar, stämde bra överens. Komprimeringsfunktionen i programmet, som är en vital del av signalbehandlingen, visade sig stämma bra överens med NMT:s komprimeringsfunktion, sånär som på en relativ minskning av värdet vid starka insignaler. Programmet ska nu användas på Cochleaimplantat-sektionen vid Uppsala Akademiska sjukhus för att pröva ut individuella inställningar till användare av cochleaimplantat.

Samspel i ensemble : En musikpedagogisk studie om gymnasieungdomars interagerande i ensembleundervisning

The purpose of the study is to observe how the participants of the study interacted musically through verbal, non-verbal and musically resonant expressions. Verbal communication was expressed in discussion of the music's tempo and to clarify for ensemble participants from where they we?re going to play and sing. Non-verbal communication could be used to gesticulate an instrument or a melody. For example, the movement of a hand could symbolize notes on a musical stave to indicate the notes placements.

Konstruktion och implementering av mobil prototyp: The Lovebomb

The idea for the thesis ?Construction and implementation of a mobile prototype; The Lovebomb? originates from doctoral candidates Rebecca Hansson and Tobias Skog from PLAY Research Group at the Interactive Institute in Gothenburg. The object of the master thesis is to construct two working LoveBomb prototypes, one mother console belonging to the LoveBomb and blueprints for both. The LoveBomb (the picture to the right shows a possible design) is intended to encourage people to express themselves emotionally when situated amongst strangers in public spaces. Two buttons control the device, which contains a radio transceiver.

Optimering av ultraljudssändare- och mottagare avseende räckvidd, strålningsvinkel och energiförbrukning

Embedded Systems Lab at Umeå University is currently part of a research project with the purpose to examine the behavior of dairy cows inside a barn. Each cow needs to be tracked with a precision of 50 cm, and since GPS-technique has poor functionality at indoor environments, an indoor positioning system needs to be developed.Embedded Systems Lab has already developed an indoor positioning system using IR-light and radio, but since this system demands extensive infrastructure and is rather expensive, an alternate positioning system using ultrasonic pulses and radio is being examined.In this report the range, beam angle and current consumption of ultrasonic transmitters- and receivers are investigated. Three different driver stages for the transmitter is tested, and two amplifier solutions for the receiver. The report also describes how the length of the transmitted ultrasonic pulse affects the received signal, accessibility of a ?shadowed? signal, and the effect of different sound frequency..

Effekten av ett probiotikum i en besättning med hög incidens spädgrisdiarré

Magnetic resonance imaging (MRI) has the potential to be used for the diagnosis and study of osteoarthrosis in the equine tarsal region. In the development of new diagnostic MRI techniques cadaver specimens are often used. To allow the use of cadaver legs for these types of studies it is important to know the effect of time after death on the MRI image. Since the relaxation times are temperature dependent, it is interesting to examine whether the time after death and the temperature of the cadaver may play a role in the image appearance and quality. The radio pulse sequences that show the different types of tissues are also important to know when pathological evaluation with MRI is used.

Rytm- och pulsutlärning till klassiska violinister : Hur ser undervisningen ut?

Syftet med studien är att ta reda på hur fiolpedagoger på en kommunal musikskola undervisar i ämnet rytm och puls. Det saknas mer omfattande forskning inom området och vi ville därför göra en fördjupande studie som behandlar denna frågeställning. Det didaktiska perspektivet är vår teoretiska utgångspunkt och studien har sitt fokus på vilka hjälpmedel och metoder pedagogerna använder sig av när de lär ut.De metoder vi använde för att få svar på våra frågor var den kvalitativa intervjun samt videoobservation. De båda informanterna som medverkar i studien arbetar och verkar idag som fiolpedagoger på en kommunal musikskola. Resultaten visar på vilka olika sätt de båda informanterna undervisar i ämnet rytm och puls.

Utveckling av Breakoutbox för Fuel Flow Transmitter

Development and construction of an electronic Breakout box is the main work for this thesis. The box is a part of a test system for the component Fuel Flow Transmitter and should convert signals to be suitable for a frequency counter. A previously constructed Breakoutbox for this purpose is being old and needed to be recreated. So SAAB Aerotech, Aircraft services, the company for the thesis work wanted to construct a new, more sustainable Breakoutbox adapted to a more modern technology. The signals to the box comes from the transmitter and should be converted to suitable signals for a frequency counter so it can show pulse and time difference between the signals.

Påverkas röstkällans egenskaper av förändrad stående kroppshållning? En experimentell studie av otränade mansröster

The aim of this study was to investigate whether a direct shift inpostural alignment results in changes in voice source characteristics. Ninemales with untrained voices were recorded standing in ideal posturalalignment and in the deviant postures swayback and kyphosis characterizedby extended hips and a slump back respectively. The voice source wasderived from the audio signal by inverse filtering. The parameters pulseamplitude, maximal flow declination rate, level difference between the firstand second voice source partials, closed quotient and the normalizedamplitude quotient in relation to subglottal pressure were compared betweenideal postural alignment and swayback and kyphosis respectively. Resultsindicate an impact of changed postural alignment on the voice source.Swayback posture gave significantly less pulse amplitude and maximal flowdeclination rate and significantly higher subglottal pressures thus resulting ina less effective phonation.
