The aim of this project is to find a concept solution for a wireless transmitting system, installed to transmit data from a hydrophone of the ocean floor down by a wave power generator to the office on shore. The project is a literature review in which previous observations and tests are analyzed and put together to find a solution. The result was a comprehensive solution that includes an acoustic modem to transfer captured information from the bottom to the surface, wirelessly through the water. The information is then sent fron the surface on radio waves through the GSM network to the office on land. Between under and over water there are components to convert information between acoustic waves and radio waves, but also various types of modulation, such as amplitude and frequency modulation is required..

Increased competition in the IT industry has sparked a need for developing faster innovation processes with more predictable output. One of the biggest issues when it comes to achieving a faster flow through the innovation process lies in managing its high degree of variation. Proposing a solution to this problem, Lean Software Development (LSD), was developed to provide a framework for how IT companies should organize its software development process to achieve increased speed and quality. This study examines to which extent LSD, as a set of values, principles, methods and tools, can be used to improve flow efficiency in the innovation process. A case study of a multinational IT company was made by conducting ten semi-structured interviews with current employees.

The purpose of this study was to look at how clients, in the Swedish criminal justice, experience their involvement in treatment programs. The spotlight in the study was to examine which helpful and unhelpful factors are involved in a treatment process, in the view of individual experiences. The study is based on a qualitative method, with interviews as an instrument for collection of data.The result is summarized in three fields; is it possible to show vulnerable, the therapist and the meaning of the program. The result is based on interviews with six informants; five of them have been partaking in treatment programs in prison and one in the probation office. The study shows that partaking in treatment programs in prison is combined with problems in aspect of the different roles criminals play in prison.

The effects of the deregulation of the electricity market 1996 in Sweden on short-term hydropower regulation are unknown. This report investigates patterns in subdaily regulation in the Ångerman River Basin during the period 1993-2011. Differences in subdaily flows and zero flow events between the periods 1993-1995 and 1996-2011 were studied by analyzing hourly data from 8 regulated and 8 unregulated locations with four subdaily flow variation indices. No correlations between the market deregulation and the regulation intensity in the Ångerman River basin were detected. The number of days natural ranges of variability were exceeded and the magnitude of subdaily variation were significantly higher at regulated locations.

Mathematical models possible to simulate are of great importance in order to make successful projects in the aircraft manufacturing industry. An aircraft fuel system is very complex, containing pipes, tanks, orifices, valves and pumps. The principal of this thesis is using the tool Easy5, which no longer is considered reliable enough in terms of development and support. This thesis tries to evaluate the Modelica language as a possible alternative to Easy5. To make this evaluation, the components concerned in the fuel library in Easy5 are implemented to the Modelica language.

The report is about efficiency of a current production group where there is no clear production flow and there are some buffers between the operations. The efficiency is done with the help of a tool that is calledWork process of flow production which is used by Atlas Copco CTO. The most obviously results are that the lead time drops from 25 hours to 425 minutes and that the balancing loss decreases from 85 % to 8 %. The report focus on decreasing transports, decreasing buffers, more reliability in lead time and quality. And a more stimulating labour content for the workers is another result..

This report will give the reader a description of principles how to measure the abrasive mass flow in a waterjet cutting system. The work began with a visit to Water Jet Sweden AB to get a closer look at the problem. When the analysis of the problem was done the criteria were defined in the form of demands and desires. The main task of the criteria was to guide the search for the solution. The work proceeded with an extensive search for abrasive flow meters along with obtaining information about flow measurement in general. When the search for abrasive flow meters resulted in nothing all the efforts were concentrated on finding a principle of measurement that could cope with the criteria.

The study is a qualitative survey with the purpose to through interviews with Employment Office social workers examine their perception of possibilities and obstacles in the employment market for immigrants. This purpose is specified through two specific problems; how are cultural and ethnic affiliations portrayed in relation to what is perceived as Swedish in the communication with Employment Office social workers and whether they reckon that the specifications in the employment market are pragmatically or normatively motivated. The materials are presented using a social constructivist perspective and in relation to previously conducted research and our chosen theory. The results are presented and analyzed in themes. The main conclusions drawn from the interviews are that it primarily is the individual prerequisites that are central, but that structural factors also affect the entry into the employment market.

The aim of this study was to get a deeper understanding of how employees at NCC Construction Sverige AB experience health promotion activities. The purpose was to identify and uncover the process of meaning constitution concerning health promotion within each subjective individual. To achieve this deeper understanding the participants were asked to answer a carefully formulated phenomenological question in a self-report. The received reports where analysed according to the method of Meaning Constitution Analysis. The result showed that both office workers and construction workers exclusively refer health promotion to bodily functions even though there where some differences in type of activity they focused.

The public administration and its officials have a number of values which they have to relate to in their work. The values are a set of democratic and economic values.This study?s purpose is to examine how the officials at the National Insurance Office in Sweden give priority to these values. The study is performed by interviews with officials at two insurance offices.The study shows that the officials in a high degree value the democratic values legal security and public ethics. In turn they experience that productivity, which is an economic value, is being promoted in a high degree from the management.

At the turn of the year 2009/2010 there was a change in the regulations on sickness impact. This led to 328 persons in County of Kronoberg had an expired period of sickness benefit from the Social Insurance Office (Försäkringskassan) when they reached the maximum time for sickness or temporary disability compensation. These individuals were offered introductory programs with the employment services. The purpose of this study is to investigate how the population with expired period of sickness benefit from the Regional Social Insurance Office in the County of Kronoberg (Försäkringskassan Kronoberg) is described in the initial stage, and to explore how individuals who achieved expired period of sickness benefit from the Social Insurance Office (Försäkringskassan) talks about the meaning to get an expired period of sickness benefit regarding economic and social issues. The study was inspired by Grounded theory.

Flooding events are no longer rare, floods occur all over the world. Accordingly, it is vital for the society and different authorities to work with flood mapping. To meet the goal of Uppsala kommun to map the risks of floods in Uppsala län, a map of the different areas around Funboån which are inside the area of risk for flooding have been developed.In the work, cross sections and the water flow have been measured. Moreover, an echo-sounding have been carried out in Funboån to map the bottom topography. From the bottom map and laser scanned data covering the study area, a terrain model was created.

The dissertation were performed on SP, Technical Institute of Sweden. The dissertation were carried out on the measurement technical department, this dissertation is a part of a bigger project, project ClampCal. One of SP?s returning assignments are flow-measurement. When flow-measurement is performed, the flow has to be stopped so that a meter can be installed in the pipes where measurement is going to take place. At every stop there is time delay in the flow which causes the customers to loose money. This is why SP wanted to find a better solution so that measurement can be done without any stops in the flow. Usage of a so-called Clamp-on meter was considered, but since the measurement uncertainty is too large it takes some investigation on the parts where the largest uncertainties occur and thus find a solution that can diminish the uncertainty as much as possible. The parts that were considered to have an opportunity to reduce measurement uncertainties were the fluid temperature, its characteristics and the pipe geometry and its characteristics. For the fluid temperature a Pt100-sensor with four different radii for various pipes was used.

The purpose of this study is to examine how employees in an organization using flexible work practices, experience that passive face time influences the evaluated of them. Further, the study aims to understand to what extent that perception of passive face time motivates the employees to spend more time at the office than is necessary for their work situations. The study concludes that employees in general perceive that passive face time does influence how they are evaluated and that this perception motivates employees that are relatively newly employed by the company to spend more time at office..
