The cost of construction projects have increased during the past few years. Different actors in the construction industry work together to advocate various measures to mitigate these cost increases. One of these measures is to try to improve the efficiency in the phase of production. By striving for a kind of standardization with a constant quest for improvement, the productivity can increase while the costs of production fall.For this thesis has a case study been conducted at the construction company JM AB which is seeking this. They call the approach structured production and have implemented various measures to achieve a more productive output.Based on information from reconciliations, the cost and the spent hours of craftsmen have been analyzed at the company where the case study took place.

The aim of this thesis is to study preschool-teachers? experiences from using the computertablet as a tool for learning and teaching, in order to gain knowledge of how the integrationalprocess of information and communications technology (ICT) in preschool has progressedsince its instatement. The background that caused interest to make this study was the rapidprogression of the use of ICT-tools in childrens? everyday lives and the troubles that havesurrounded the process of integrating these tools into preschool-practices. The theoreticalbasis for the analysis of the research lies within the socio-cultural perspective.

During my time as a student of education I have learnt that it is my responsibility, as a teacher, to adjust the ways in which I teach to the needs, abilities, experiences, and thoughts of each individual child. What I have not yet gained much knowledge on is how to go about finding the children?s thoughts.In this thesis I investigate the interview as a method of finding out how sixth graders think about their mathematics education. Four children were interviewed. In addition to these inter-views, as a means of giving a broader perspective to and a greater understanding of the chil-dren?s answers, one math lesson was filmed and the math teacher was interview on two sepa-rate occasions.What I found was that a number of factors seemed to influence the children?s thoughts and answers, and that their answers were most likely not always a mirror of their thoughts.

This Masters thesis work describes a comparison between two different methods for estimation of the down channel (base station to mobile subscriber) in Wide-band Code Division Multiple Access (WCDMA). The first estimation method, Optimal Feed-forward Channel Estimation (OFCE), is a conventional method that bases the estimates on data that is known to both sender and receiver, so called pilots. The second method, Decision Directed Channel Estimation (DDCE), is an elaboration of OFCE. It also uses user data for estimation. Simulations show that DDCE, in comparison to OFCE, does not attain an improvement in signal-to-noise-ratio (SNR) for high bit error rates (BER).

Practice of mathematical proof increase the understanding of mathematics anddevelop creativity skills, problem solving, communication, logical thinking andreasoning which are all important tools not only within the subject of mathematicsbut also important tools for the society in which we are living. The aim of this projectwas to investigate whether it is accurate that proof and proving has a subordinate rolein mathematic education in the upper secondary school in Sweden. This was done byconstructing of a digital survey that was sent to approximately 100 practicingmathematics teachers in a normal size city located in the middle of Sweden. Theresults of the survey show that the teachers consider themselves comfortable withtheir own skills in teaching proof. Paradoxically, the results also show that there is alack of teaching of proof and proving in the upper secondary school, although the newcurriculum puts more focus on proof and proving..

Syftet med denna studie är att ge en insikt i hur elever med kombinerade läs- och skriv och matematiksvårigheter tänker och resonerar vid problemlösning.Tre elever i år 8, som alla ingår i samma specialundervisningsgrupp i matematik, har arbetat med olika typer av matematisk problemlösning, såväl individuellt som i grupp. Med utgångspunkt i deras arbete skapas början till en grundad teori.I forskningssammanhang behandlas ofta denna kategori elever (med kombinerade problem) som en enhetlig kategori som jämförs med t ex elever med enbart matematiksvårigheter, normalpresterande elever osv. Denna undersökning visar dock att de svårigheter eleverna uppvisar är av mycket olika karaktär.Studien omfattar tre delar: en presentation av fältstudien och resultaten från denna, en metoddel innefattande en pilotstudie som koncentreras på datainsamlingsmetoden samt en omfattande litteraturstudie som behandlar problemlösning och inlärningssvårigheter..

The purpose of this study is to examine sex/gender relations amongst staff in public libraries who have taken part in projects related to information technology. This is done through e-mail surveys and telephone interviews with staff who have participated in the development of the two library websites Mina bibliotek and Biblioteket.se regarding their experiences. The theoretical basis for the analysis is two gender theoretical perspectives with reference to technology. The first perspective is represented by Yvonne Hirdman?s theory concerning the gender system, in which women and men are kept apart and in which there is always a hierarchy where men are higher up, and Hanna Westberg-Wohlgemuth?s theory concerning sex marking of job-tasks.

The aim of this study is to investigate which management control mechanisms evolve in companies that receive funding from Venture Capital companies and why the management control systems evolve in the way that they do. A case study was performed on three Swedish high technology companies, that all received funding from Venture Capital companies for the first time in 2006. Merchant?s framework, defining all management control mechanisms as either, results control, action control or personnel control, was used to structure the study. Results show that the companies that received Venture Capital all increased the use of management control mechanisms within results control, action control and personnel control.

Several studies have shown that the Swedish labour market for different reasons is characterized by ethnical discrimination and that people who have another cultural background than Swedish are being excluded. Most studies done within this area have been focused on why it is harder for immigrants to enter the labour market and identifying the contributing mechanisms for this phenomenon. Instead the aim of this study was to see how the immigrants view their own cultural identity and background and how they perceive that their cultural competences are being valued when they apply for a job. To examine this, the following problematic was used: How does a person who has been brought up with both the Swedish culture and another culture look at using this as a cultural competence when they apply for a job. Two different theories were then applied to analyze the problematic, Erving Goffman´s theory about Stigma and Norbert Elias theory about the Established and the Outsiders.

AbstractThe background to this essay is previous experience in working in a preschool abroad. The teachers I met there did not relate to the children in the same way that I?m used to in Sweden. In my view, different expectations on the children, made them not make use of the children?s full potential to develop.The starting-point for this essay is the?life world perspective?.

The purpose of this study was to find out what the educators view on the working method Matte på burk in preschool looked like. I also wanted to find out what the educators thought about the working method. My questions are:How does the educators in preschool experience the method Matte på burk?What do the educators in preschool believe that Matte på burk can give the children?The study was carried out through a qualitative interview study with six educators. During the interviews with the educators it became apparent that the method not only focused on mathematical exercises.

This study is part of an international project, The Third Wave Project. The project aims to conductstudies with students of different cultures to see what they value as important in mathematics andmathematics learning. Part of the project involves carrying out a survey, the WIFI study. The WiFistudyaims to examine values of mathematics teaching that may affect student learning. The valuesthat are examined in this study are based on the mathematical values which are described by Bishop(1991).

The information market is constantly changing. With new and improved information technology more people get access to more information faster. However, the number of people educated to handle information also increases. Business intelligence has for a long time been a well-known tool for companies to be competitive. Because of the increased access to information the competition between companies has intensified and more people have become aware of the advantages of business intelligence and how it can help them compete.

The waveform of a radar signal affects the resolution in velocity and distance. The ambiguity function is used as an aid for analysing narrow band radar signals simultaneously in time and frequency. An analysing tool for wide band radar signals is missing.This thesis describes a generalised ambiguity function to be utilised for study of wide band signals. Waveforms are further synthesised with help of the developed analysing tool. The aim is to start with a certain ambiguity function and find a waveform that reproduces the same ambiguity function.Mathematical formulas are presented and implemented in Matlab to produce the wide band ambiguity function.
