Identifiering av synkronmaskinsmodell genom SSFR-test

At the Division of Electricity at Uppsala University there is an experimental rig forhydroelectric generators. The experimental rig?s vital part is a 12-pole synchronousmachine, whose electrical characterizing parameters (resistances, inductances andtime constants) are unknown. The aim of this thesis is to characterize the machine inits current state by perform a Standstill Frequency Response (SSFR) test. From theanalysis of the measurement data, which is a part of the test, a set of basic parametershave been received.

Omega System Kalibrering: Strål X-Separation mätning och kalibrering

Micronic Laser Systems AB produces and develops machines for the photo mask production market. One of their products is the Omega machine which exposes photo masks using 5 laser beams simultaneously. It is important that the distance between the each laser beam, the x-separation, is the same. The x-separation is today measured by exposing a photo mask with a certain pattern and thereafter measured with a metrology system. This takes to much time and it is desired to find a faster method to measure the x-separation without loosing precision.The task for this master thesis is to improve an existing measurement method which uses a calibration mask.

Kronandelsrelaskopering, en ny metod för att fastställa gallringsbehov?

In today´s forestry, assessments of needs for thinning are based on basal area measurements. This is an indirect measurement. The approach and the developed assessment tables are based on an assumed production forest, which implies that management proposals in stands that deviate from the basic model may be misleading. Since Walter Bitterlich in 1948 launched the idea of the relascope, several modifications have been developed for different purposes. In common is that all are based on a certain angle measurement principle.

ABC-kalylering i grossistföretag -modelldesign och effekter

Background: A large number of companies works as a link between manufacturers and final users. These companies buys and stores goods to be able to deliver when a need comes up later in the chain. The storage could have a negative effect on profitability and therefore places great demands on the management control systems. ABC as a method has been used with some success in manufacturing for over ten years. In wholesale companies the method is not frequently used.

Luftutsläpp från järnmalmsproduktion : - Strategier för systematisk luftkvalitetsmätning

The mining company LKAB extracts iron ore in three areas in the north of Sweden, Kiruna, Malmberget and Svappavaara. The iron ore is refined and in the pelletizing plants the material is rolled to finished pellet product. The different steps of pelletizing plants causes among other things emissions to the air. It occurs occasionally stops in the production and the emissions are vented via an emergency chimney without purification. The aim for this work is to look into how LKAB may improve their monitoring of air emissions and control of ambient air quality and the analysis methods which are suitable for measuring.

Projekteffektivitet inom tekniska utvecklingsprojekt : Vilka faktorer påverkar projekteffektivitet och hur kan dessa mätas?

The purpose of this thesis is to identify the factors that drive efficiency and effectiveness in technical development projects performed at A?F?s department of product development. In addition to identifying and analyzing these factors, the thesis also analyzes what needs to be taken in to account in order to implement a measurement system that is able to both monitor and control the identified factors.The thesis has been performed in a qualitative manner. It is based on interviews with people from several different technological companies, within different lines of business, all of which are customers to A?F?s department of product development.The results show that there are seven critical factors for project efficiency and effectiveness.

Den synliga övervakningens effekt

The purpose of this essay is to explain which factors influence the disciplinary effect of visible constant surveillance on the people under surveillance. In order to do this we have used recorded video from a tv-show called Big Brother, which is characterized by this kind of surveillance. In addition, an open-ended interview was performed with one of the participants from the show. We have, based on a number of theoretical assumptions, as well as reflections from the interview, precisely defined expected symptoms of the participants, that would indicate when the disciplinary effect was low respectively high. Our observations and analysis allows us to conclude that the disciplinary effect of surveillance in many situations is counteracted when surveillance is constant, leading to relatively low levels of disciplinary effect in Big Brother..

Harmonisering av redovisningsstandarder

Earlier models that measured de facto harmonization of international accounting mainly used indices and other related statistical models. Those approaches do not account for the relative importance of individual balance sheet items or expense items being harmonized. This paper therefore proposes a different approach using Runsten?s (1998) permanent measurement bias model. That way it is possible to quantify the harmonization process by accounting for differences among companies.

Nya metoder för vibrationsmätning på vindkraftverk

This project has revolved around finding better ways of overseeing vibrations of the gearbox at a wind power station. The gearbox has been a huge problem at the stations located at Gässlingen and the sooner the warning of an incoming breakdown is at hand the more money you can save from preparations. The work has been carried out together with Askalon AB in cooperation with consults from ÅF. Askalon is a company with a department focused on overseeing vibrations and it is in collaboration with that department the work has been carried out. During this work, new positions for the sensors and new methods of gathering and analyzing data have been worked out. This was then implemented at a wind power station to be tried out on site.

De kan säga dig vad en pommes frites är, men inte en potatis... : En studie över amerikanska överviktspreventiva skolbaserade program

This study has focused on obesity prevention efforts in schools in the United States of America. The study was conducted in two states, Oklahoma and New Hampshire. In New Hampshire, the study was focused on more minor efforts which were the "CSHP", HEAL, Early Sprout, FIT, AFHY, 5210, and Kids CATCH Club. In Oklahoma, the focus on the study was on the program It's All About Kids.Method: Unstructured interviews and observation, analysis from an national policy document. A total of seventeen interviews conducted, seven of them in New Hampshire and ten in Oklahoma.

Hur lidande nyttjas för att producera effekt : En kvalitativ textanalys av reklamfilm vars huvudsakliga innehåll är djur

For the sender of television advertising, it is important to utilize content that gives effect, especially to get the receiver?s attention and then maintain it (Hägg, 1998). What is the content of a commercial that creates effect? Previous research focused on the impact that commercials have on the receivers. A discussion of which content that produced effect in commercials does not occur.

Metoder för kartläggning och analys av nätförluster i lågspänningsnät

An important process for grid companies in order to reduce power losses in electricity distribution grids is to figure out where and how they appear. This report describes the factors that cause power losses in low voltage distribution grids and methods for how they could be measured and analyzed. Measurement data for consumed and injected energy were collected for twelve low voltage distribution grids owned by Gävle Energi AB in order to analyze the size of the power losses and how the measurement uncertainty affects the collected data. Then models of three of the grids were created in MATLAB in order to analyze the data and the power losses were calculated to be compared to the collected data. Curve fitting were also used as a method in order to analyze the power losses from collected data.The results show that the losses in the studied grids are low.

Intentionen till generositet - Hur den påverkas av gener, hormoner och religiositet

Many studies have pointed out that generosity depends on different things like gender, age and nationality. We wanted to see if predetermined factors like genetics also had an effect on the intention of generosity. There is a ratio between the index finger (2D) and ring finger (4D) that is determined by the levels of testosterone in the amniotic fluid and that have had some significant effect on personality attributes like musical and leadership skills. We wanted to see if that ratio had any effect on the intention of generosity. We experimentally examined a group of priest student and two groups of young handball players and let the groups answer a survey that included a sort of dictator game and we photo copied their hands to get their 2D:4D-ratio.

Mätdatainsamling

Rapid Granulator is one of the world's largest producers of granulators, which is a kind of grinderwho grinds discarded plastics to granules which later can be reused when pressure molding plastics.The company wanted help in developing a new, or alternatively extending their previous,measurement equipment. The old equipment was hard to use, required changes in the code fordifferent measurement scenarios and had a limited array of measuring quantities. Rapid had an ideaof a similar concept only with a greater number of input ports, better range of applicable sensors andan advanced yet easy to use interface. The system is supposed to be placed at Rapid's test departmentwhere it will be used as a tool for finding faults and provide data which can be used for furtherdevelopment of the granulators.The project's members accepted the task and immediately began searching for suitable componentsfor the system. After the search was completed a list of costs, limitations, sensors, I/O's anddevelopment environment was presented to Rapid's staff.
