Stroke is one of the most common diseases in Sweden and the third most common cause of death (National guidelines concerning stroke, 2000). Dysphagia is a common problem for stroke patients with almost 50 percent of patients suffering from severe swallowing dysfunction (Axelsson, Asplund, Norberg & Eriksson, 1989). The purpose of this study was to investigate how stroke patients with dysphagia experience their swallowing disorders. The method used was a qualitative literature study. An analysis of content was carried out using ideas and inspiration from Graneheim and Lundman (2003).

This work aims to evaluate the possibility of using a graphical programming language to develop software for a digital signal processor. A fixed-point digital signal processor called Blackfin BF-537 is used for this. Instead of using conventional programming languages, like C or assembler, for software development the possibilities to use a graphical environment to fill the same purpose are examined. The development environment primarily used is NI LabVIEW, but also the use of Mathworks Matlab Simulink is investigated. A variety of programs consisting of various signal processing operations and utilities are developed using these development environments.

This report describes the procedure in which we accomplished our task, which was to implement a present algorithm. This was made using C++. The algorithm is developed by Sasan Gooran, who is our examiner in this project. The algorithm uses an iterative method to produce the halftoned images. The reason for this project is to speed up the existing program which is made in Matlab.

This report describes a synchronous machine model with magnetic saturation in d-axis, neutralconnection and electrical exciter interface for the transient simulator PSCAD/EMTDC. It hasbeen designed and verified in comparison to the regular machine model in EMTDC.The performance of the model is very good when incorporating a linear as well as a saturatedmagnetising inductance. The dynamic deviation is only thousandths to ten thousandths perunit. By using a cubic interpolation of the saturation curve, the model gives a good representationof the saturation effect. The open source code implementation of the synchronousmachine model gives the possibility to easily adapt the model to specific requirements.The derived model makes it possible to simulate a synchronous machine with its excitationsystems, e.g.

The purpose of this paper is to examine how seams in an interactive system should be managed. Seamsin this study refer to the boundaries that arise when users move between for example differentsoftware, products or positioning systems. These seams are a cornerstone of the relatively unexploredarea called seamful design, which is based on that users can avail highlighted seams through activeparticipation in the use of a system. To analyze this area, seamful design is applied to the developmentof an interface of a smoothie vending machine. This smoothie machine thus provides the analyzedinteractive system, which the research questions are applied to as well as answered by.

Rapporten tar upp och behandlar ämnet betalväxlar utifrån en utvecklares perspektiv. Två företag som varit i eller nära inpå processen att utveckla en webbshop har intervjuats och jämförts med utbudet hos ett antal olika betalväxlar. Intervjuerna har visat ett resultat som är mycket troligt att man som ny utvecklare kommer i kontakt med i början. Positionen kan då vara både som utvecklare eller som ägare till webbshoppen. Det gick även att konstatera att det fanns ett antal betalväxlar lämpade för olika kunskapsnivåer.

Detta examensarbete har haft som uppgift att undersöka möjligheterna för hur man skulle kunna förbättra gränssnittet för användarna av WIS, Webbaserat informationssystem (1), genom att göra webbapplikationerna mindre dataintensiva. Examensarbetet görs i samarbete med Know IT Candeo AB i Luleå som är utvecklare och förvaltare av systemet. Examensarbetet tar upp några exempel på hur många webbapplikationer fungerar och är uppbyggda idag och försöka se det från ett perspektiv på hur man skulle kunna förbättra gränssnittet för användarna med hjälp av asynkron webbkommunikation. De bakomliggande principerna för asynkron webbkommunikation kommer att behandlas för att sedan kunna beskrivas mer specifikt i AJAX(Asynchronous JavaScript and Xml) tekniken och Microsofts implementation av AJAX som heter ASP.NET AJAX (3). För att kunna utvärdera om asynkron webbkommunikation är användbart i just detta specifika projekt ska några enkla prototyper tas fram..

Storing kinetic energy in a flywheel allows for more efficient driving of electricvehicles. Research in this area is in progress at Uppsala University, where a flywheelwith magnetic bearings encased in a vacuum chamber is being constructed. To makethis possible methods for measuring the current through the electromagnets in thebearings and temperatures in the flywheel need to be developed. This has been thepurpose of this report. The current measurement resulted in a resistive method, andthe implementation of eight measurement circuits in the system.

In today's social work there is an ambition to work evidence-based in order to improve quality and competency in business. This study is made in a disability administration which has introduced a common approach towards users for all employees. The approach is called low arousal approach. The purpose of the study is to investigate how a method takes hold and implements within an organization. The empirical data is analyzed by theories of professionalization, idea dissemination and translation.

In a comparing survey this thesis investigatesclassification systems for dams in Sweden, Norway,Finland, Switzerland, Canada and USA. Theinvestigation is aiming at an understanding of howpotential consequences of a dam failure are takeninto account when classifying dams. Furthermore,the significance of the classification, regarding therequirements on the dam owner and surveillanceauthorities concerning dam safety is considered andreviewed. The thesis is pointing out similarities anddifferences in the line of dam safety.The survey of dam safety is firstly based upon legalrequirements in the different countries andsecondly on guidelines regarding dam safety. Damowners generally are ultimately responsible for thesafety of their dam, and often have their ownroutines regarding how this safety is to be achieved.In this thesis, however, the legal requirements aremainly focused upon.The investigation has resulted in an outlining ofeight areas, where the classification systems in thevarious countries have been compared.

The purpose of our qualitative study is to investigate how the caretakers, in the elderly care,interpret and manage the issue of alcohol problems in elderly people. We have beenperforming semi-structured interviews on 9 people, on different levels in the elderly care.There were 3 elderly care managers, 1 nurse, 1 assistance administrator and 4 auxiliarynurses, who all, at some level, work with alcohol problems in elderly people. Thoseinterviews were performed singularly, with one exception: we interviewed an elderly caremanager and her 2 auxiliary nurses at the same time. To analyse our empirics, we have usedthe theories of Power and Ageism. Our study shows that the auxiliary nurses, who are theones who must deal with these problems, have great difficulties to perform their work becausethey have no qualified knowledge about alcohol problems.

The aim of this Masters thesis is to examine the accessibility in public libraries for persons with dyslexia and visually impaired persons. In order to do this, library services, information and attitudes have been studied. Data have been collected through interviews and studies of documents, in particular guidelines for library service to disabled persons. The theoretical starting point of the analysis is Professor Michael Bucklands different aspects of access to information. He discusses six types of barriers that must be overcome if access is to be achieved.

?This is a study of two school extern homework activities dedicated to helping students with their homework. The questions at issue are 1) how are the homework activities organized when it comes to financing, planning, marketing and implementation? 2) Who participates as staff as well as students and what are the requirements for participants? 3) What are the reasons for students to attend school external homework sessions? Material was gathered by a survey among the students at the activities and by interviews with principals for each activity. Two main findings are that the homework activities are almost exclusively visited by students with immigrant background and that the main reasons for participating are difficulties with the Swedish language, and parents not being able to help their children with homework.

This study of leadership is comprised of two parts. The first part presented in this study is a theoretical study of leadership and the second part is an empirical study. The empirical study is comprised of six qualitative interviews that examine the perception of leadership among educators working at a school in the inner city.The work is based on the following issues; Do educators think that there is a link between educational work and leadership? Do educators see a link between leadership and goals, and guidelines that are written in Lgr11 and the Education Act? Does the perception of leadership depend on what training the educators have?In this study I use a hermeneutical approach where I try to create an understanding of the interviewees by interpreting their responses, actions and opinions during the interviews.The material gained from the empirical study has been analyzed and interpreted and then related to the theoretical study. The results show that leadership is something that everyone in the school system is in need of whatever their education.

Value-at-Risk (VaR) is among financial institutions a commonly used tool for measuring market risk. Several methods to calculate VaR exists and different implementations often results in different VaR forecasts. An interesting implementation is historical simulation, and the purpose of this thesis is to examine whether historical simulation with dynamic volatility updating is useful as a model to calculate VaR and how this differs in regard to type of asset or instrument. To carry out the investigation six different models are implemented, which then are tested for statistical accuracy through Christoffersens test. We find that incorporation of volatility updating into the historical simulation method in many cases improves the model.
