Studie av 3-dimensionella sidoeffekter vid etappvis schaktning i Götatunneln, J2
Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

- Jag är den jag var då - det är förutsättningarna som har förändrats? - en postkolonial feministisk studie utav invandrarkvinnors berättelser om identitetskonstruktion och förändring
Postcolonial feminist theory says that ones identity is constructed by severalfactor, not only gender but even culture, ethnicity and class imbedded in the socialcontext. This paper examines what happens to women's identities if the socialcontext changes. Does an identity shift occur? By interviewing five women fromBosnia-Herzegovina I try to understand the affects migration has on women?sidentity. Postcolonial feminist theory says that our identities are constantlychanging, as their constructing factors.

En studie kring processen att som IT-konsult skifta affärsmodell genom försäljning av en standardiserad lösning.
Due to increasing international competition and new technology IT-consultants has been forced to oversee their business models lately. The main purpose of this study is to investigate the process and consequences of a shift in business model for a consultant by using a methodology based on action research. The empirical foundation consists of a field study with observations, notes, interviews and business related documents. The case describes a consultant?s process of shifting business model from profits based on man-hours to selling a standardized system.
Stereoseende i realtid
In this thesis, two real-time stereo methods have been implemented and evaluated. The first one is based on blockmatching and the second one is based on local phase. The goal was to be able to run the algorithms at real-time and examine which one is best. The blockmatching method performed better than the phase based method, both in speed and accuracy. SIMD operations (Single Instruction Multiple Data) have been used in the processor giving a speed boost by a factor of two..
The Psychology Driving&Barriers to Skunk Work Project
The Psychology Driving and Barriers to Skunk Work Projects (referred to throughout this thesis as the paper) represents a study predominantly on Tetra Pak from a selective perspective, the innovators. Innovators both past&present whose initiatives contribute to the well being of Tetra Pak as well as one from Ericsson were consulted. As with individuals, organizations possess definable characters that are influenced by the various stages of their life cycle. Theories of corporate life cycle phases and organizational character analysis were therefore employed to identify and explain organizational barriers to skunk work leaders&managers. Predicated on the Organizational Character Index survey developed by William Bridges PhD (himself a recognized leader in the field of transition management) and administered to sixty-one managers within a Tetra Pak business unit established the benchmark.
Att synliggöra, reflektera och utveckla. En Learning study om bråkräkning i matematik.
AbstractThis study is about describing the pre- internationalization phase and to studycompanies that are in this phase. We are trying to capture characteristics of decisionmakersin the pre- internationalization phase, to then compare the theoretical materialwith empirical material from case companies. Then in the final stages of the thesis, wewant to account for if we managed to answer our research questions. In the method, wegive a description of the approach selected in conjunction with the study. The study isqualitative and we used both primary and secondary data, with a deductive approach.The theory chapter will consider the most relevant theories that are related to the topic,which is internationalization, pre-internationalization, international entrepreneurship,and the psychology behind personalities, attitudes, and how these can affect theorganization's strategic decisions.

Temperature monitoring during transport of test samples
Quality is the main focus in management of all laboratories. Accurate results of the analyses are not only determined by the analytical procedure but also by preanalytical factors. In the total analytical process of clinical specimens, there are many possible preanalytical sources of error. Monetoring of temperature on test samples of the transport boxes is one way to reduce the mistakes in the preanalytical phase.In this study, four laboratories from primary health care were invited to participate. The temperature has been measured on test samples of the transport boxes being delivered to the laboratory.In three cases the temperature remained within the limits, but in the fourth case the temperature varied more than the allowed interval.
Avståndsmätning med Hög Noggrannhet till Låg Kostnad
Active sensors are used a lot in the society and industry, for example to gain better control over processes or to get proximity sensing features in different products. Within industry there is great interest in developing safe automation products that can be controlled with high accuracy but still at a low cost.The goal of this project is to develop a prototype of a non-contact rangefinder that measures distance using infrared light. The sensor is to be used for various applications in industries with relatively high accuracy and be compact, but at a low cost. By implementing a rangefinder into a product, more accurate detections of an object?s presence can be done.In this project a new distance sensor, EPC600 from ESPROS, was used.
MILJÖCERTIFIERINGSSYSTEMET MILJÖBYGGNAD I PRODUKTIONEN : En fördjupning inom området ?Material?
The environmental assessment system Miljöbyggnad is a Swedish system initiated by Bygga-Bo-Dialogen to assess buildings with regards to three main areas; ?Energy?, ?Indoor climate? and ?Materials?. A building can obtain three different classifications depending on how well it manages to meet the demands. GOLD is the highest classification and is followed by SILVER and BRONZE. The majority of the measures needed to comply with the demands are done during the design phase.
