In this qualitative study of students? methods of calculating subtractions, I have used interviews, subtraction exercises and analysis of teaching material. The purpose of my study was to explore which methods students in grade three uses when calculating subtractions. I also wanted to highlight which strategies the students use and their comprehension of the concept of subtraction. In the study, I also highlight the different pedagogical ideas on which the teaching material is based on and the students? choice of methods.  The study shows that the students choose to use the methods?deduct? and ?kind of number? independently.

This Degree project summarizes how it is to work in the CAD program Revit Architecture. This was done because AQ Arkitekter in Eskilstuna is interested in how Revit works. Especially compared to AutoCad which is the software they are using today. Will their work become more efficient with the new software?The starting point was to find out how it is to work with Revit when you only used AutoCAD Architecture before.

In this paper we examine how young women present themselves on their weblogs. The main purpose of this study is to get their own opinions and thoughts about their own blogging, to see if we can find norms for how they present themselves and how the presentation online matches themselves offline. We put this in relation to information technologies, social software and Computer mediated communication, CMC. It´s also in our interest to see how the phenomenon of blogs, its role and methods of communication have changed and developed in the last few years, and whether there are differences in the way people use it according to age. The major finding is that, unlike previous research, the women in our study tend to be themselves in their weblogs and they do not manipulate their identities.

The purpose of this study is to examine how six teachers, who work in two different schools, assess the methods Friends and Mombus in terms of bullying prevention. The Curriculum for elementary school (Lpo 94) emphasizes that it is the employees of schools who carry the main responsibility for preventing bullying among pupils. One of the main results of this study is that teachers, in addition to their work with Friends or Mombus, also need to use alternative methods to prevent bullying. Examples of these alternative methods include ?Emotional Intelligence? as well as ?friendship massage?.

In this report a system for Rapid Control Prototyping, RCP, is evaluated through animplementation of the motor control methods Field Oriented Control, FOC, and Space VectorPulse Width Modulation, SVPWM. The evaluation emphasizes on time-consumption andresource utilization on the used hardware and on usability for of software.A new mechatronic laboratory is under development at ABB Corporate Research in Västerås. Itwill be used for both mechanical and motion control design using existing and new hardware.The control structure in a traditional robot system will be interfaced to a rapid prototypingsystem which should allow easy changes to algorithms at different levels in the system.The system designated for this project comes from National Instruments and constitutesLabVIEW Real-time and FPGA module as the software tools. The hardware is a NI Single-Board RIO (Reconfigurable Input Output), sbRIO, development board including a Field-Programmable Gate Array, FPGA, from Xilinx and a microprocessor from FreescaleSemiconductor. Graphical programming is performed in the LabVIEW environment, andthrough Xilinx tools the LabVIEW FPGA code is compiled to VHDL code.A pre-study was carried out to clarify the concept of RCP and investigate different systems forRCP and their traits.

This study centres on learning to read and methods for teaching reading skills. The aim is to provide a survey of the concept reading skills and the methods developed on the basis of different theories and the methods preferred when teaching children in primary school and why. The study is based on interviews with eight teachers who are working on a dailybasis teaching Swedish in preschool class or lower primary school. The result of my study is that the majority of teachers do not use a specific method, but rather combine several different methods, thus adapting instruction to each individual pupil. .

The aim of the study was to look at a particular work group of housing supporters, whomhave implemented two special working methods in their work. The methods have been implemented by two of the housing supporters that also have special education in the methodsSOC (Sense of Coherence) and solution focused brief therapy. The study is based on anethnographic observation and analysis of documents that are used in the implementation. To analyse the information that was given at the observation and in the document I´ve used a theory which illustrates the significance of developing professions so their knowledge become legitimate. I´ve also used a theory that illustrates the importance of implementation and how it´s done at its best.

Abstract The purpose of writing this thesis was to improve methods during requirements engineering phase. Usercentred system engineering has some problem areas, which are examined and verified to create a new guideline for developers. This guideline tends to make requirements engineering more effective and help developers create more concrete requirements. It is not uncommon that system development projects ends up with unsatisfied users or delay in deliveries. The reasons are different kinds of communication problems between users and developers during verification of requirements. There is a therapy model, called solution-focused therapy, used in family and individual therapy. The model focuses on solutions for the future instead of problems in the past.

The purpose of this study is to investigate the reading methods that pedagogues, active in classes 1-3, use in the first stage of learning to read and how they consider their own choices of methods. In the theoretical background I sort out the basic differences between synthetic and analytic methods of acquiring the skills of reading. The analytic reading method means that the skills of reading starts with the complete text in order to later analyze the parts of the text. The synthetic method approach is based on a reading method where the parts are linked as a whole. The two methods are considered antipodes but can also be looked upon as complements in the current governing documents.

The aim of this thesis is to analyse and if possible improve the communication, mainly seen from a pedagogical perspective, between the IT company (Nostratic) and their clients in a first meeting. The analysis covers the preparation part, communication during the meetings, the technical terminology used during the meetings as well as the follow up of the meetings. Due to the lack of research within this area and the lack of personal experience on my part, the conducted study has been explorative with the use of qualitative methods. Although my first aim was to put emphisis on the pedagogical part of the communication, I found while conducting the study that there were other areas of higher importance to analyse in order to improve the customer meetings. Unfortunately the company went bankrupt in the middle of my study which resulted in me not beeing able to try out the potential improvements.

In this report a new gear concept is evaluated using the magnetic finite element method (FEM)software MagNet and Ansys as well as the mechanical FEM software Abaqus. The gear conceptis evaluated in terms of maximum torque capability, torsional stiffness, gear ratio and efficiency.ABB Corporate Research has proposed a new gear concept which should be less expensive thangearboxes used today. The new concept is called aMagnetic Harmonic Traction Drive and usesthe principles of a harmonic drive gear to achieve a high reduction ratio. The gear conceptreplaces the wave generator used in traditional harmonic drives with magnets and uses tractioninstead of gear teeth to transfer the torque. The main components in the gearbox are the magnets,the flexspline, the magnetic portion and the circular spline.

Very often the interesting variables are explained by several underlying variables and in statistical analyses it is common to study the relationship between variables and groups of variables. Because of this multivariate analysis is commonly used in both science and industry. There are two problem with both univariate and multivariate analyses. One is when the variables are correlated. The other is when the number variables of exceeds the number of observations which makes the matrices algebra used in the analysis impossible to execute.

Since the demands from authorities regarding lower energy consumption havebecome increasingly strict, this puts new pressure on designers and builders, who notonly have to ensure an esthetically pleasing building, but also make sure it issufficiently efficient to pass under new laws and regulations.This thesis takes into consideration a wide range of various parameters and theireffect on a building?s energy consumption. For this evaluation a computer softwarecomparison between the two programs Autodesk Ecotect Analysis and AutodeskProject Vasari was performed.Autodesk Ecotect Analysis is better suited for studies made on individual factors whileAutodesk Project Vasari is better used in experiments regarding the geometricalshape of the stucture itself.The results from the two different software tools used, give us both differences andsimilarities. For instance, both software programs produced the same resultsregarding the importance of the windows of the buildings to ensure a highly energyefficient building, both when it comes to the windows size and their U-value..
