A unified model of stress and affect consciousness was proposed. The connection between affect consciousness and perceived stress was studied. Teachers (n = 19) were interviewed using Monsens affect interview, followed one month later by a questionnaire containing Perceived Stress Scale (PSS), State-Trait Anxiety Inventory (STAI-S, STAI-T) and Twenty Item Toronto Alexithymia Scale (TAS-20).Statistical analysis showed no connections between level of total affect consciousness and perceived stress. Though there were some indications of a negative relationship between affect consciousness and trait anxiety. There were also indications, using a complementary analysis, of a connection between level of affect consciousness on the subscale distress in the interview and perceived stress.

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.

A mobile testing application using Unity was developed to analyse what impact button sizes and button layouts has on the accuracy of touch as well as the time to finish a labyrinth. This was tested on a Nexus 4 phone. 28 users navigated a small object through a labyrinth in which they collect keys to open the door to the exit. Each participant did the test 6 times with different combinations of button size and button layout each time, done in a random order. Hits, misses, completion time, order of button size and order of button layout was collected and then visualized using R.

In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

Severe floods caused by heavy autumn rains in year 2000 raised the question whether measures to reduce the damage from high water levels, in the area surrounding lake Glafsfjorden and along the river Byälven down to lake Vänern, are possible. One option is to reduce flow resistance along the river and thereby lower the maximum water level a given inflow would cause. Good knowledge of hydraulic and hydrological conditions is necessary in order to estimate the effect of such flow-reducing measures. In order to quantify such effect a 1-dimensional hydraulic flow model has been set up for the river Byälven using the software package MIKE 11. The model is more detailed, especially concerning topography and bathymetry, than earlier models used for studies of the river.

This thesis will address a problem concerning availability of information systems at an enterprise within the financial sector and its external suppliers, so called trusted third party. The information system resides on the internal network of the enterprise and must be available to both employees of the enterprise and the trusted third party simultaneously. This contradicts the company policy which disallows third parties access to the internal network. The HAVECA-model introduced in this thesis provides a framework of methods, each solving a sub problem identified in the model. The identified methods are hardening, verification, control and assurance, together supplying a method for continuously securing the internal network against a trusted third party.

Through this study we want to enlighten how different companies work with their internal branding and how well they succeed in this process. We also want to examine if there are any differences in this work depending on the companies market position. Following question is used to investigate this process;- In what way and how well are companies working, depending on market position to implement and maintain their work with the internal brand?For the study a theoretical model was created based on our existing theory. The model contains three main variables; create, communicate and uphold; i.e.

This is a qualitative analysis that, based on systemic functional linguistics, or SFL, and genre theory, has aimed to study the genre pedagogical implications on written language as they occur in narrative stories and expositions whilst the model is introduced. Systemic functional linguistics is a linguistic theory that views the organisation of language as functional options for meaning; language is a set of resources to channel meaning through realisation. Genre theory elucidates the pragmatic and educational uses of SFL in the categorizing of language in configurations of meanings as they are set and understood in different cultures.  The purpose of the survey is to do so with focus on successful and less successful writers by attempting to answer two primal issues:How is development of written language in reference to the introduction of the genre pedagogical model visible in the studied texts?How does genre pedagogical teaching influence successful and less successful writers as visible in their writing with a certain purpose?To answer these issues the survey is based on narratives and expositions written by high school students who have been divided into two groups according to the purpose of the survey. One text in each genre has been written by the students before and after lessons based on the genre pedagogical learning wheel explaining the relevant genres.

Forecasting stock market returns is an interesting topic since more and more Swedes enter and invest in this market. Theory implies, however, that such exercises should be impossible. The aim of this thesis is to investigate the possibility to forecast future stock returns by looking at macroeconomic variables? history. The study is limited to the Swedish market as it is based on the OMXS30-index which represents the 30 most exchanged stocks on Stockholms¬börsen, the Swedish stock exchange.

This paper aims to investigate the systematic risk exposure of Swedish hedge funds using a modified Fung & Hsieh (2004) asset-based style factor model. The results show that the average Swedish equity hedge fund and fund of funds had a significant positive exposure to the equity market portfolio and the spread between small cap and large cap stocks (SMB) during the sample period. This is consistent with our a priori expectations and previous international studies. We do not find the expected systematic fixed-income related risk exposure for the fixed-income hedge funds and fund of funds in the sample. The empirical material used in this study is taken from a publicly available fund database maintained by the Swedish Financial Supervisory Authority (Finansinspektionen).

The objective of this diploma work is to investigate a set of Multiple Input Multiple Output (MIMO) channel models compatible with the emerging IEEE 802.11n standard. This diploma work validates also advanced, innovative tools and wireless technologies that are necessary to facilitate wireless applications while maximizing spectral efficiency and throughput. MIMO channel models can be used to evaluate new Wireless Local Area Network (WLAN) proposals based on multiple antenna technologies. The purpose of this thesis is to investigate means of channel models and their implementation in different environments such as: Matlab, C++ and Advanced Design Systems (ADS). The investigation considers also a comparison between the channel models based on theoretical data and parameter setup to the channel models based on statistical characteristics obtained from measured data.

Quality can be defined as the ability of a business to satisfy their customers? needs and expectations. Total Quality Management is defined as the way to prevent, appraise and improve the entire organization to increase the product quality. In order to systematically increase quality in an organization, there are different quality systems in use. One example is process management, which is to divide the activities of processes.

In Sweden approximately a half per cent of the population have diabetes mellitus type 1. Self-care responsibility is a part of the treatment. Orem?s self-care theory has been used as theoretical framework. The purpose was to describe what it means to be young and have diabetes mellitus type 1.

Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.

This thesis work contains a litterature study about electrical motors in general and how PWM-patterns for brushless DC-motors can be made. A suitable method has been implemented as a simulation model in VHDL. A simulation model of a brushless DC-motor which describes the phasecurrents, torque and angular velocity has also been made. The motor model made simulations easier for the complete PWM-system. The design was synthesised and tested with a prototypeboard including a SPARTAN II FPGA.
