This diploma work has been conducted for the consulting company Ramböll inUppsala, Sweden with the purpose to perform a study with the calculation programFEM Design 9.0 made by Strusoft. The aim has been to find out if it is possible to gainadvantage by utilizing more advanced 3D software for design calculations, instead ofthe traditional methods currently used in construction works.The method of approach has been to model an existing warehouse building with theprogram FEM Design, and then compare the results with those attained with FrameAnalysis and hand calculations. These results are then analyzed. An evaluation is maderegarding to what benefits can be achieved using a more advanced 3D-model.The results of the study show that the differences between the methods are not ofany significance with regard to the design of the steel frame. However in morecomplex materials such as reinforced concrete, the differences become more notable.The conclusions drawn by the authors of this study into FEM Design are that theeducation requirements of the program are higher than for simpler programs, whosepurpose are solving predetermined problems.

An industry in distress was the breeding ground for a noted pricing strategy, labeled name-your-price. The industry was the music industry and the pricing strategy bears reminiscence of how medieval buskers earned their living during the dark ages; by letting the customers decide how much the good was worth, embodied by a thrown coin into a hat or similar collector. Translated into the contemporary corporate environment of today, where technical innovations provides access to the intellectual property for free, a few mighty economic actors have once again turned to the strategy were it all started; letting the customer set the price. The hat has been replaced by a box for your credit card number and the live music by a MP3 file, but the similarity is striking. The business model have been applied in other industries as well with various levels of success, thus the purpose of this thesis is to set up a framework for where the name-your-price strategy is applicable.

In recent years the liberal representative democracy has been subject of a substantial critique because of its inability to accommodate difference and createa genuinely democratic political process. One such critique comes from the theory of deliberative democracy. Supporters of deliberative democracy try to promote a model of democracy that take its vantage point in free and equal deliberationbetween all relevant actors in a political community. This model has with some success opposed the aggregative model of democracy, and in important ways turned the attention to the potential of deliberative processes.However, the deliberative model is still somewhat underdeveloped when it comes to issues of diversity and difference. This essay deals with such deficiencies by analysing deliberative democracy in the light of the critiquelaunched by difference- and radical democrats.

In the next few years the pollutants loading at the Slottshagen wastewater treatment plant in Norrköping is going to increase due to the reason that one of the waste water treatment plant in the district will be shut down.A survey of how these different pollutants are divided in the treatment process is therefore necessary for mapping out both the loading and treatment efficiency.This can be achieved by studying mass balances.Mass balances were carried out for the water treatment process for the mechanical/chemical,biological and the chemical stage.The mass balance studies show that the treatment efficiency was very good. However in order for the mass balances to be quite consistent and to ensure complete coverage of results and conclusions i.e. more reliable results, sludge samples should be collected and taken at different times per day and the influent rate should be investigated.In this work mass balance has been set up in order to illustrate and identify the factors that should be considered and taken care of for further estimation using mass balances in the future. Furthermore this survey results in a calculating model for the mass balances at thisplant.This calculating model is used as a tool to facilitate future calculations for mass balances for the water treatment process at Slottshagens wastewater treatment plant.Moreover it provides a basis for carrying out further estimation of the treatment process in the near future.In this project the importance of some operating parameters was also taken in consideration.This calculating model can be modified so that calculations of such operating parameters i.e. sludge loading and sludge age can be easily performed.Such information can be used further to evaluate different operation alternative in order to ensure an optimal use of the treatment process with in the plant..

Introduction: First line managers in the public sector, are under a great pressure from both senior management, leadership, politicians and often from a large group of employees. Few studies have been made on the first-linemanagers psychosocial work environment, even though in the studies found that the manager affects their employees work environment.Aim: How first line managers in municipal elderly describes the psychosocial work environment on the basis of demand-control - support model.Methods: The study was conducted through individual interviews with six first line managers. Respondents were recruited through a strategic selection in a medium-sized municipality in Västernorrland. The interviews were conducted using an interview guide. Qualitative content analysis with an deductive approach was used as a method of interpretation of the results.Results: First line managers point out the difficulty in balancing the requirements and several managers also mentioned the importance of having clear role descriptions and objectives.

In order to broaden the understanding of work motivation the aim of the study was to compare how three different teams within the same organization constructed motivation. The three teams consisted of post sorters, team leaders and mailmen. Three focus group interviews were conducted with three men and eight women. The interviews were transcribed verbatim and thematically analysed with QSR NUD*IST. The result showed both similarities and differences in the construction of work motivation in the three teams.

Computers together with Internet have been growing enormously, during the last decade and the area of information technology has been growing in the same speed. As long as the surrounding environment evolves, the business models must within the IT-area, keep the same pace. So, how do business corporations handle this change to attract customers? How do the dominant business models look like? In many cases, they are apparently much the same. But what differences can we see and what areas can be improved? We have showed that the IT area isn?t just one, it consist of several segments.

A piezoelectric injector was modeled, in this Master Thesis Project which was carried out at Scania CV AB in Södertälje, in GT-Fuel. GT-Fuel is simulation program from Gamma Technology.The simulation model for the piezo injector was divided into a hydro-mechanical system and an electrical system (Piezoelectric element). First the hydro-mechanic model was duplicated from Advance Continuous Simulation Language model (ACSL). The simulation results were then compared to the ACSL, to verify that the hydro-mechanical system was modeled correctly. The simulation results for the electrical model were also compared with a Simulink model.

Heat is distributed to the district heating customers through pipes with water as a heat carrier. The district heating system is complex. To decide what is leakages from the district heating net versus what is the water consumption of the plant, is difficult. Therefore, the purpose of this master thesis is to establish a model where the district heating net?s leakages but also the water consumption of the plant can be followed daily. The project is performed at Vattenfall´s district heating power plant in Uppsala. Information is gathered through discussions, drawings of the plant and guided tours of the plant.

The purpose of this essay is to try to understand the relationship between the structures of modern working life and the development of burnout. By using the method of qualitative interviews we wanted to see if the Effort-Reward Imbalance Model could be applied to the data we had collected. Two questions have been highlighted in our research:        ? Is it possible to establish a relationship between the structures of modern working life and the development of burnout among the subjects interviewed?  ? Is it possible to explain the development of burnout among our interviewed subjects through the Effort-Reward Imbalance Model?    Our theoretical frames are the general theories of the modern society and the modern working life as developed by Anthony Giddens, Ulrich Beck and Zygmunt Bauman. We have also used Johannes Siegrist?s medical-sociological Effort-Reward Imbalance Model (ERI-Model).

This study aims to seek knowledge of the salutogenic model within geriatric care. This is done by problematizing the female geriatric care personnel?s everyday life and conditions. The study?s comparative empirical focus includes interviews with ten women that work within geriatric care, at two different workplaces.

The aim of this thesis was to examine how a coordinator at a social welfare project in support of job seekers, achieve results in his efforts to reduce the number of clients with social assistance. The method of data collection was a mixture of open thematic interviews and semi- structured interviews with open questions. The coordinator was interviewed four times during the length of the project. In addition, two of his clients were interviewed. The data also includes a report from the relevant social services and other documents such as newspaper articles.

Due to increasing regulations regarding new diesel vehicles particulate matteremissions the new Scania truck, Scania Euro 6, has been equipped with a particulatefilter. This component effectively stores the particles in the exhaust gas but must becleaned in order to prevent itself from clogging. The filter is cleaned through aprocess named regeneration which is a thermodynamic process in which thetemperature of the filter is raised through fuel supplied to the exhaust gas.The purpose of this thesis is to contribute to the development of improved controlstrategies of the temperature during the regeneration process through thedevelopment of model-based controllers. These controllers are designed in order tohave good performance in stationary as well as automatic regeneration.In order to develop these model-based controllers a model of the system isconstructed. The model is described as a linear thermodynamic grey-box model withflow varying parameters, showing good results in validation.The model provides a simulation environment during the controller design, which isfocused around the development of linear regulators with the exhaust gas mass flowas a scheduling variable whose size determines controllers? mode of operation.

The purpose of this report is to create and develop a model that streamlines and helps the innovationprocess of an idea owner and also in the development of ideas.This model should be able to apply for workshops and in innovation advice or business devlopment. I used the qualitative method in my essay just to get a maximum clear data collection, where the seven respondents were included in the interviews. However, much of the information retrieved from the theory books and research/science articles, in order to answer the research/Sceince question in the best possible way.

Simulations of simulink models using Kalman filters are often very time-consuming. This problem depends mainly on the fact that the Kalman correction has to be performed at each sample instance through the whole simulation. The goal for this thesis work is to reduce that time-consumption for the filtering part (the integration partis treated in a complementary report) of a simulation. Furthermore a Matlab routine to perform parameter tuning and finally a graphical user interface is developed.The filtering part of the simulation in this thesis is based on an Extended Kalman Filter (EKF). The time optimization of this filter considers searching for the possibility to replace the today?s existing Matlab functions that is used to perform the filtering calculations.
