An evaluation: how have the goals of ?Vårdkedjeprojektet? been implemented at the treatment centre of RällsögårdenThis evaluation was commissioned on behalf of the treatment centre of Rällsögården. The aim of this study is to evaluate how the goals of ?Vårdkedjeprojektet? (VKP) have been implemented in the institutional care at the treatment centre of Rällsögården. This study was focused on the following questions: a) how is the function ?internal coordinator? experienced by staff at Rällsögården, b) in the function of internal coordinator what aspects are thought of as effective/non-effective concerning the cooperation with ?external coordinators? and contact with clients and staff, c) how is Vårdkedjeprojektet and its treatment approach ?Community Reinforcement Approach? (CRA) experienced by coordinators, clients and staff and d) how well is the aftercare functioning for clients who have finished their treatment at Rällsögården, and still participate in VKP?The choice of research method was triangulation; a combination of qualitative and quantitative methods.

There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..

This thesis has been a part of Forsmarks Kraftgrupp AB's evaluation of a turbulencemodel used in simulation of turbulent flow called PRNS (Partially Resolved NumericalSimulation). This model has promising properties and may be of use in savingcomputational resources. The purpose of this thesis was to analyze this model andcompare it with industrially applied models such as k-omega SST and LES (Large EddySimulations).PRNS works as a hybrid of the k-omega SST and DNS (Direct Numerical Simulation)where a constant, RCP (Resolution Control Parameter) with a value between 0 and 1are selected. This constant is then used in the calculations and determines thebehavior of the simulation. When RCP is set to zero the equation are the same as fora DNS simulation and when RCP is set to one the equations for k-omega SST issolved.

The project has contained everything from identification of user and customer needs and requirements to evaluation and building of a prototype.The result is a chair with a frame of tubular steel and there is nothing like it in Kinnarps AB?s assortment today.

This master thesis was done for a company called BRUKS which is active in woodprocessing,bio-energy and bulk material handling industry. The idea for the master thesis wasto develop a new reclaiming method for silos where wood chips are being stored. A mediumsegment of between 1000 ? 5000 m3was defined as the segment with the most sales potential.Two different concepts were produced, one for new constructions and one for rebuildingalready existing silos.In the beginning of the master thesis a lot of time was spent on visiting different BRUKSoffices and customers to get an overview of the industry and the product. This informationwas the basis when the idea generating phase began.

Business is changing and so are society?s expectations. Companies are expected to take responsibility for their trade and the context they are operating in, by looking at socially, economically and environmentally aspects. Many companies handle it by implementing corporate social responsibility (CSR) to their line of action. This is often handled by collaborating with other organisations, such as non-governmental organisations.

This thesis work is a 30hp D-level assignment in design as a co-operation between MälardalenUniversity and Scania CV AB in Södertälje. The purpose was to develope a close fitted catwalk.The market has seen an increasing value for these types of applications and have the ambition to keep up with the rest of the competitors. The catwalks of todays standards shall be estetical attractive, have a non slippery surface and be costefficient.While working with this project I have spent a lot of time with the concept proposals and with the evaluation of the concepts, resulting in a final CAD model and a approximation of the cost estimate. The new catwalk fulfils all the new recommendations and rules as sharp edges, ADR, the height of the stepup and a non slippery surface with built in drainage..

The purpose of this study is to the increase knowledge and understanding of the meeting between children with Arabian as native language and a Swedish school library. The study is made as a qualitative investigation built on interviews with eight-year-olds and eleven-year-olds. Only the childrens needs and views are considered. The study is centred on twelve key issues and aims to document the childrens thoughts and views of reading as well as their reading habits and their use of the school library. Through the childrens own words their evaluation of reading and literature, their abilities to assimilate the text and their de facto use of the books can be known.

Today environmental management systems (EMS) are common documents (more correctly, a combination of documents) that direct, steer and regulate environmental efforts within many companies. The intention of EMS is that its guidelines are reflected in how the employee carries out his everyday work tasks. This study aims to illuminate the attitudes that exist regarding the EMS at ALSTOM Power Sweden. By using questionnaires and interviews as a method to communicate with employees,a study of the existing attitudes regarding the EMS was carried out. The results were analyzed categorically and statistically and show that there are consistent attitudes among employees, but that there are also inconsistent attitudes.

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.

This thesis is about developing a design that provides improved vacuum seal between a lead coating and a plastic coating during plastic extrusion processes of cables. This report is a part of the course MSGC 17 for Bachelor Engineers in mechanical engineering.The work is performed at Nexans Norway AS in Halden where they have a production of high voltage cables for sea-, and offshore industry. A problem they face is that they do not get enough good seal at the attachment to the plastic extrusion machine. They want to achieve a vacuum between a lead coating on the cable and a plastic coating of the cable for plastic extrusion, which is something they do not achieve today. The thesis is thus to come up with a design that provides better sealing against the cable.The work involves a construction part with the phases of product development processes.

The automotive market is currently undergoing a historical change where stricter emission legislations and ever increasing fuel costs have intensified the search for effective alternatives to the conventional internal combustion engine, which has resulted in a substantial trend towards electrification of powertrains. Storage of electrical energy is the fundamental component in this technology where the lithium-ion batteries are currently considered as the most appropriate solution. Lithium-ion batteries, however, as other types of batteries, can only be used efficiently and durably within a specific temperature range.This Master thesis has been carried out in collaboration with Electroengine in Sweden AB, situated in Uppsala, which has an ongoing project regarding development of a modular battery system for electric powertrains. The project is at a stage where an initial prototype has been developed which provides the foundation for this thesis. The study has addressed the battery system performance from a thermal perspective, in order to validate the ability of the system to create a thermally serviceable environment for the lithium-ion battery cells.
