Design och implementation av ett stamningsförebyggande system med DSP teknik
Uppgiften består i att konstruera och designa en DSP lösning för att förebygga stamning. Genom att en signal tas in på en mikrofon och bearbetas i en DSP därefter skickas ut på en hörlur.Signalen som behandlas i DSP:n ska frekvenshöjas och fördröjas.Pitch och fördröjning ska kunna justeras m.h.a. en omkopplare.Till hjälp fanns utvecklingskortet eZdspF2808 från Texas Instruments och en in/utgångsförstärkare.Tidigare erfarenheter av DSP från Texas Instruments saknades. Att lära känna utvecklingskortet var därför en del av arbetet. Det bestod mest i att läsa användarguider från Texas Instruments hemsida.Utvecklingskortet saknar en DA-omvandlare, en sådan konstruerades..
Mixtekniker
A discussion regarding the alignment and measuring procedure of propeller shafts has arose due to the competing situation in the industry, and higher standards from the customers. An estimation of the deflection of shafts in different alignment situations has been made with help of FEM-analysis and beam theory. This has been analyzed and compared with the experience from Rolls-Royce AB suppliers of shafts. An evaluation of measuring protocols has been made and the result indicates that there is a correlation between the deflection of the shaft and the run out. Results from a measuring test performed by Balino, Spain, verifies this conclusion.
Konsten att mäta tjänstekvalitet : En utvärdering av tre instrument för att mäta tjänstekvalitet i kollektivtrafiken
The purpose of this study is to analyze and evaluate the suitability of the three instruments SERVQUAL, SERVPERF and Zone of tolerance to measure service quality, from the respondents' perspective. This study has been carried out by a quantitative method in which respondents answered three questionnaires, which was based on the three instruments. The SERVQUAL instrument is a revised version based on criticism by Carman (1990). It is based on the five dimensions; reliability, responsiveness, assurance, empathy and tangibility, with 22 items in which each dimension is associated with a number of items. SERVPERF is the instrument most similar to SERVQUAL and is also composed of the same five dimensions.

Systematiskt arbete för att hantera osäkerheter vid mätning : vid Q-Med AB i Uppsala
This report is about helping Q-Med AB in Uppsala to start its implementation of uncertainty of measurements analyses in their manufacturing department. Prior to this, the company relied solely on personal experience or did not take this uncertainty into consideration at all during different kind of measurements, which means that some of the processes that the company previously believed were within specified acceptance limits, will actually fail when considering these sources of uncertainties.Q-Med AB needed some sort of instruction to help the company, in a systematic way, to investigate different types of disorders that are affecting all kinds of measurements. This instruction includes a short summary about measurements and uncertainty of measurements in general and a detailed procedure about how these uncertainties are going to be handled in their daily work.The goal was to be able to use this instruction to systematically locate, eliminate (when possible) and analyze all kinds of disorders when measuring. Q-Med is using a lot of different types of instruments when measuring different types of quantities, including temperature, mass, pressure and density. This instruction will hereafter be used for every instrument, regardless of quantity and type of instrument.The instruction is tested through 4 different kinds of measurements, for mass, temperature and humidity.
Framtagning av nytt mätsystem för mätning av energiförbrukning i mikrovågsugnar
The report describes a measuring method for analysis of energy consumption measurement in microwave ovens. Concurrently that the awareness of the environment evolves the demands are growing for more power saving products. This is also counting within the Home Appliance business, which is Whirlpools business area. Whirlpool is therefore interested of launching microwave ovens with documented low power consumption. To be able to implement this, both asserted measuring equipment, that fulfils all demands, and a standard procedure is required.

Tryckalgometri hos friska hästar :
There are no reliable, objective and simple methods today for measuring pain in horses. The purpose of this study was to evaluate and describe measuring of mechanical nociceptive threshold (MNT) values with a pressure algometer in clinically pain free riding horses at the riding school of Strömsholm. In this study there were 24 horses. Tape recording and electromyelografi (EMG) was used in an attempt to increase objectivity in the examination. MNT increased with age, however sex and colour had no influence.
Kraftanalys och framtagning av mätanordning för vertikala vindkraftverket Lucias bärarmar
The project contains a force analysis of the vertical axis wind turbine Lucia's supporting arms and a measuring device to experimentally measure the forces is made. The forces between the supporting arms and the tower are calculated theoretically and then simulated by a computere. A measuring devise is then designed to measure the forces experimentally. The forces acting on the attachment between the supporting arms and the tower is primarily the centripetal force, gravitational force and the aerodynamic forces on the rotor wings. The maximum forces were theoretically calculated and is 13.38 kN along the x-axis, -0.25 kN along the y-axis and then 0.5 kN along the z-axis.
IT-kompetens : utveckling av ett mätinstrument
Problem: In society of today corporate competence is an important factor for survivor and development. IT is developing rapidly and can not be ignored by companies. Then need for people with IT-competence is conquent increasing. A survey of corporate IT-competence is therefore of interest for companies as well as for local authorities. To determine the IT competence within an organisation, this competence has to be measurable.
USA:s förändrade Europapolitik USA: EU-politik sedan kalla krigets slut. En utrikespolitisk förändring i stil eller substans?
This thesis aims to describe and characterise the foreign policy change the United States has experienced towards Europe. This thesis claims that the United States is presenting a more supportive attitude today towards the development of the European Union. This more positive attitude has developed during successive U.S. administrations and has become visible since the end of the Cold War.Washington is today less ambiguous and less ambivalent towards the integration of Europe. The United States appreciate that a common foreign- and security policy in Europe is in accordance with American interests.

The project has contained both a theoretical study consisting of a literature review and practical studies in the workshop with the objective to identify an end mill?s main parameters and the relationship between an end mill?s geometry and the manufacturing processes.
Alternativa drivmedel i den svenska vägtrafiken år 2030 : En utvärdering av den svenska regeringens målbilder
The Swedish government has set up the overall goal that no net emissions of greenhouse gases can occur after 2050. A sub-target has been developed for road transports which states that the use of fossil fuels must be reduced with 80% to 2030 in order to be completely abolished to 2050. A public inquiry mapping how this can be achieved was handed in to the government late in 2013. The use of alternative fuels for road transport, both biofuels and electricity, is expected to give the biggest contribution to the reduction of the use of fossil fuels. The inquiry sets up a number of goals for how much the use of alternative fuels must increase to 2030 in order to reach the overall goal and which instruments that are needed in order to do so.The aim of this thesis is to evaluate how these goals can be reached and what the most likely obstacles that may hinder the reaching of these goals may be.

Marknadsmässig spannmålshandel
The agriculture throughout the world is becoming increasingly deregulated and this has affected the prices of raw materials to fluctuate at a higher degree than earlier. This in turn has made it interesting and in some cases even necessary for the trader as well as the
producer to gain knowledge about the trade instruments available to ensure a good enough price for their produced goods. This study encompasses a number of ways to
trade grain and oil plants in order to clarify what differences there are in the several contracts that exist in the present situation, economical as well as practical. The various trade instruments available to the producers on the Swedish market are described in the theoretical part of this study.
The study also contains a simple arithmetic example, based on historical prices collected from grain traders and trading floors, in order to point out the differences in the
economical outcomes depending on the business strategy used to sell the produced goods.
The study shows the importance, as a producer, of being able to use and take advantage of the different trading instruments at hand to monitor and exploit the shifts in the
market. From an economical point of view it is not enough to just excel at farming but knowledge about the market functions and the trade instruments at hand is also required
to be able to secure a good enough price for your goods.
