To measure losses in a transformer with today?s methods is either slow or insecure. There s a new method developed by Alstom that hasn't been actualize in to a test-system and that has been the assignment in this project. The idea is built on a switched system and a CLR- circuit in the resonant frequency. The test-system has a calculated power-loss that make the efficiency to be as high as 99,8% and in reality over 95%.

Background: It has been shown that EDI can yield positive effects within companies. Which effects are possible for a company to direct assign to the introduction of EDI and is it possible to estimate the total effect.Purpose: The purpose of this study is to estimate and analyze the effects of using EDI in electronic business. We also want to contribute with a model for measure and estimate the effects of EDI.Accomplishment: We have studied literature concering EDI and realized a preliminary studie in form of interviews with experts to establish deeper knowledge of EDI. We have also tried to estimate the effects obtained in companies in three different businesses, power, government and transport industry.Result: To obtain as good effects as possible it is important that the co- oporation is built on trust and engagement. Before implementing the EDI-system a thorough overhaul of the processes in the company should be done, involving both the top managers and the staff.

This study examined the psychological processes of autonomic arousal and distress, erroneous beliefs about sleep, worry about sleep, selective attention and monitoring and safety behaviours related to sleep, on the subject of daytime impairments associated with insomnia. The psychological processes were evaluated against as follows: sleep measures, anxiety, depression, medical disease and the use of medications. The measure daytime impairments complied with the established research diagnostic criteria. A correlation analysis indicated that psychological process, anxiety, depression and one of the sleep measures are associated with daytime impairments. The results of a multiple regression analysis proved that only erroneous beliefs about sleep, worry about sleep and safety behaviours related to sleep are linked to daytime impairments associated with insomnia.

The purpose of this study was to investigate if preferences for high- and low context communication differed significantly between individuals from individualistic and collectivistic cultures, living in a multicultural environment. A quantitative survey was used as method and the survey was answered by 150 students at Jönköping University and Uppsala University. Two self-assessment scales, obtained from previous studies were used to measure the degree of the two cultural dimensions and communication styles. Two multiple regression analyzes were performed to investigate the connection between collectivist cultures preference for high context communication and individualistic cultures preference for low context communication, that has been found in previous studies. Two ANOVAs were also performed to investigate differences in communication style depending on sex and length of stay in Sweden.

This study aims at norming a new objective method to track and measure jaw movements in 3D (three dimensional) during chewing in the young adult population (n=41, age 22-30). Norm values of the range of movements and the duration were calculated. Intra and inter rater reliability was high. Masticatory efficiency among participants was evaluated with a two-colored wax, analyzed with picture analysis software. Regression analysis was used to calculate the relationship between movement and duration variables and masticatory efficiency.

The county of Dalarna is at present carrying through a process of digitalization where traditional x-ray film is being replaced with digital detectors. Earlier used methods for dose optimization turned out not being sufficient. This report presents a method to harmonize dose levels between x- ray sites equipped with Fujifilm imaging plate systems. An exposure index, S, related to the dose level of the examination is computed to every x-ray image. S turned out to be inversely proportional to the detector dose used at the examination.

Aim: Through the review of scientific articles, this study aimed to identify which oral health-related quality of life instruments that have been used in studies to measure the oral health-related quality of life in older individuals and the application of such instruments.Method: The study is based on a systematic literature review, where 14 articles have been chosen and evaluated against a checklist. Result: The oral health-related quality of life instruments that have been used on individuals, 65 years and older, are OHIP-49, OHIP-14, OHIP-20 or OHIP-EDENT, GOHAI and OIDP. The instruments are used to examine factors associated with the oral health-related quality of life. Significant associations have been identified, among other things, between the number of teeth in static occlusion, dry mouth and the quality of the dentures, and oral health-related quality of life. Social and cultural associations have also been revealed.Conclusions: Today there exist several well functioning instruments that are used for research purposes.

Formal writing is an essential part of teaching Swedish and is fundamental for higher education and professional career. The aim of my essay is to research what didactic methods Swedish teachers utilizes in upper secondary school to improve students' abilities to write formal texts. I will also examine students? project papers in an attempt to measure the extent of formal word choice.  In the presentation of the literature I decided to use, for example, Per Olov Svedner?s perspective on writing as a process, Siv Strömquist?s manuals for essay writing and various literature regarding linguistic correctness and essay layout. Interviews with three upper secondary school teachers reveals that active feedback is a basis for students development regarding formal writing in both school and professional career.

The purpose of this thesis is to investigate if the stock market reacts differently to accounting information, depending on the stock market climate. The study focuses solely on stocks listed on the OMX Stockholm 30 during each year from 2005 to 2009. By applying the concept of Earnings Response Coefficient we can estimate how the market reacts to accounting information. The dependent variable in the equation is the market reaction on unexpected earnings, in the study described as the abnormal return on stock. For quality purposes we measure this on a ±1,5,10 and 20 days basis.

The aim of the study was to examine the competence of dental hygienists among Clinic Director´s within the Public Dental Service and Private dentists in the county of Skåne . The study was quantitative and consisted of an electronic questionnaire sent out to all Clinic Directors in the county of Skåne. A total of five hundred and thirty eight questionnaires were sent out. The inclusion criteria were the Clinic directors who employed dental hygienists who had obtained their professional degree during the last four years. Twenty nine Clinic directors responded to the study.The results showed that in general clinic directors are pleased and feel that dental hygienists are proficient in periodontology and dental caries diagnostics.

This report is a bachelor thesis presented at the department of Computer Science andEngineering at Chalmers University of Technology. The aim for the project is to find a simplemethod to measure and display physical quantities in a three dimensional room.The report describes a method to construct a system for measuring differentphysical quantities via sensors. The system must be built in a modular and expandable way tobe adaptable to different tasks.The system explained in the report consists of two parts;A physical scanner with moveable probes for carrying sensors and a microcontroller forcontrolling the probes and communicating with the next part.An application written in Java for storing the measured values and presenting them in a lucidperspective.It is possible to construct the scanner with different designs and circuitry, with multiplexers andflip-flops, to ensure that an unspecified number of probes can be added to the system and thatthey can be operated simultaneously.The Java application is written in a modular way, using a design pattern that separates eachindividual part of the application. It contains exceptions and interfaces that ensure a safe andexpandable application..

This thesis reports on the methodology and results of a study with one retailers 73 units to investigate factors of the store managers leadership that influence productivity performance in store. The study determine the impact of ten independent variables in terms of the store managers leadership on four performance measures: (3) three productivity measures: Sales Over Labor (SALOL), Sales Over Inventory (SALOI) and Sales Over Square-metre (SALOS) and (1) one profit measure: Contribution Income Over Square-metre (CIOS). The result shows that the leadership factors give no more explanation to the economic results after factors of local market condition and the store attributes are taking in to account. The store manager's leadership can though influence his or her decision-making in-store. The store manager's decision to staff the store more intense (higher service-intensity) can increase the level of contribution income over square metre in-store..

The total estimated power of the street lighting was 125 kW and the energy consumption was 500 000 kWh/year with an estimated running time of 4 000 h/year. The dominating source of light was 125 W discharge mercury lamps.

The web as an arena for news reporting and information sharing to consumers has grown for many years in the expense of the traditional newspapers. The revenue stream has however not followed the same transformation which has led to a remarkably lower profit when news and articles are distributed through the web. Banner advertising is a method that is commonly used by online magazines to generate profit where advertisers pay to expose their message. One method to measure banner ads effectivity, and indirectly, what the advertiser would pay, is through Click-Through Rate (CTR), how many clicks a banner ad receives in relation to the amount of banner views. One of the variables that play an important role in the banner ad effectivity is the placement of the banner ad.
