IKT i undervisningen : En studie kring innehåll och visioner utifrån ett lärarperspektiv
The concept of IT has developed into ICT (Information- and Communication Technology) over the years. ICT has an increasing impact in society and the Swedish curriculum (Lpo 94) highlights the importance of school to convey lasting knowledge that constitutes the general frame of reference that everyone in society is in need of. The purpose of this study was to find out how teachers perceive and use ICT in secondary school and discover the teachers? vision concerning ICT.The used approach for the study is a qualitative research with a basis of interviews. Four interviews are made with teachers from the early years of secondary school, at two different schools.
Diabetes mellitus typ 1 i allmänvården
The aim of this literature study has been to investigate the general nurse's knowledge of diabetes type 1 and its complications. The questions were: What does the general nurse need to know about diabetes type 1? What does the general nurse know about diabetes type 1? To answer these questions, a literature study has been done of 8 scientific articles. The theoretical reference study on which the study has been based is Gustafsson's SAUK Model for affirmative nursing care. The result shows that the nurse lacks knowledge in the nursing care of diabetes patients and this reflects the fact that little research has been done on diabetes mellitus type 1 in recent years.
Incentive programmes – a corporate governance perspective on Swedish commercial state owned firms
We would like to learn more about how the restrictive policy against incentive programmes affects the board’s of Swedish state owned commercial firms ability to govern management in an efficient way. We also want to find out if there are different consequences in reference to this that are not directly linked to corporate governance issues. Our empiric observations have been made in order to profoundly explore the subject and examine it through the eyes of professional individuals, all expressing different views and standpoints.
We conclude that the most efficient structure is when an active board is complemented by a well structured and individualised incentive programme. However, this thesis conclude that this structure is not possible given the current guidelines and policies employed by the state, which in turn might lead to sub optimizations in the governing..
Konstruktion av upprätningssystem för CICLoPE
Today there is no way of measuring or simulating turbulent flow in high Reynolds numberenvironments. The computational power required to simulate these conditions is not expectedto be available for several decades so instead the CICLoPE project aims at solving thisshortage by the construction of a long carbon fiber wind tunnel in which real measurementscan be made. To do accurate measurements it is of importance that the wind tunnel, 0.9 metersin diameter and 110 meters long, is as straight as possible.This master thesis treat the design and construction of a device which may be used to align thetunnel along a reference laser beam. A design is presented which allows the pipe to be alignedwithin about a quarter of a millimeter along its entire length. Contents span over severalscience fields such as physics, mechanics, control theory and electronics.The result is a theoretically correct design.
Genomisk selektion inom köttraser
Genomic selection (GS) is used for selection of breeding animals of dairy cattle. GS is though not as extensively used within the beef industry. One reason for that is the low accuracy (rTI) of the breeding value that is of great importance for the final genetic gain. Causes to the low accuracy are high effective population size, a small reference population and a genetically differentiated population. There is however a market for genomic selection with High Density (HD) tests for beef cattle.
Bildförbättring över en bildsekvens
When SKL (Swedish National Laboratory of Forensic Science) gets images to analyse, the task often is to identify a person or an object. In that work it?s important to find features. Unfortunately images from camera surveillances often contain a lot of noise, so details can be hard to discern.A simple method to improve an image from a sequence is to compute the mean of some of the images. However, the part of interest in the image has to be in the same position in all images.
Design av Digital Multimeter-modul för inbyggt testsystem
The thesis work of 15 credits has been performed to interest of Norrtälje ElektronikPartner AB (NEP) in Norrtälje. The aim of the thesis was to develop a prototype for an integrated digital multimeter, designed for one of NEP's proprietary test systems. A digital multimeter module according to NEP's requirement specification, such as physical size and accuracy should be constructed. The module should be able to measure current, voltage and resistance.The final circuit was based on the chosen analog to digital-converter, Maxim integrated´s Max134, which is the main component of the circuit for this instrument. A circuit diagram and PCB layout were made. The result of this project is a constructed DMM board.
Utlandsetablering av små svenska IT-tjänsteföretag
This master of economics paper discuss that the globalization has lead to increasing internationalization among small Swedish IT- companies in the service sector. Sweden has a long history of foreign trade but in the beginning of the industrialization only large companies that produced goods answered for the foreign trade. Before, the Swedish companies begun their operations abroad in fairly nearby markets and only gradually penetrated far-flung countries. Now this is no longer possible. When small companies nowadays seek growth in other countries there is no time internationalize with the same approaches as before, especially when the company offers a service.
Flödesanalys av plåtsammansättning : Strävan mot Just-In-Time och minskat slöseri
The Volvo Trucks plant in Umeå is a highy complex manufacturing facility where the same production line handles a variety of different models. This require flexible and agile processes with high quality standards. This thesis studies the flow of material through a production line and how Volvo can use their existing manufacturing monitoring system to optimize the flow of materials.The goal with the thesis is to identify eventual problems with the flow of materials and to deliver a few proposals on how the production line can improve its productivity. The theory of LEAN, Just-In-Time and Supply Chain Management serves as the scientific reference to this project. By analyzing the flow of material, performing interviews and observing the processes a few problems are identified.
En precisionsstudie av förstärkt verklighet som positioneringsverktyg
This study investigates augmented reality using third person perspective and what precision can be achieved by using this method. There have been prior studies in regards to precision using augmented reality, however studies using third person perspective is scarce. This study presents a solution using a static camera capturing the user as well as the plane to augment from behind. This augmented image is then transferred to a handheld device that is held by the user. Using this method the user will be free to manipulate and work with the plane without removing the device that captures the scene, a common problem when using visual reference markers in augmented reality.
Varumärkesbyggande genom marknadskommunikation : En fallstudie av varumärket Hollister
This study aims to describe how a company behind a well-established brand in the fashion industry has strategically chosen to communicate with their target market. Interviews with four individuals in different positions within the company have generated qualitative data, which is presented and analyzed in relation to the theoretical frame of reference in this study. The results show that the company does not use conventional marketing, but relies rather on marketing based word-of-mouth generated by its customer base due to its unique store concepts. Previous research has shown that this type of marketing strategy is effective and beneficial to the brand equity, a conclusion that is demonstrated to also apply to the survey object of this study. Furthermore, it is also shown that this is largely due to the distinct and coordinated image that the company maintains through strict standardization..
En indirekt metod för adaptiv reglering av en helikopter
When a helicopter is flying, the dynamics vary depending on, for example, speed and position. Hence, a time-invariant linear model cannot describe its properties under all flight conditions. It is therefore desirable to update the linear helicopter model continuously during the flight. In this thesis, two different recursive estimation methods are presented, LMS (Least Mean Square) and adaptation with a Kalman filter. The main purpose of the system estimation is to get a model which can be used for feedback control.
Varmsmidning av aluminiumlegering 6026 T9 : Warm forging of aluminum alloy 6026 T9
In this project forging of aluminum alloy Al 6026 T9 has been performed in the temperature range of 400 °C ? 470 °C. The alloy which was in the shape of a cylindrical billet was formed in a press with the aim of analyzing the effect of different forging temperatures and required press load for optimal die filling. The component?s dimensions were later measured and compared to a reference piece.

Framgångsfaktorer för en mer lärande organisation : En studie av en industriverksamhet
The purpose of this study was to describe experiences in daily social life of parents of children with psychotic illness. Five parents with long-term experience of psychotic illness have been interviewed. The frame of reference in emotion theories of Thomas Scheff and Randall Collins have been used to analyze the results. The study is qualitative and has a phenomenological approach to shed lights of meanings in daily social life. The following meanings was found: Openness with certain reservation shows that honesty is important for the feeling of solidarity, Social expectations in daily life describes the parents´own expectations as well as expectations from others.
