When searching for better and more practical interfaces between users and their computers, additional or alternative modes of communication between the two parties would be of great use. This thesis handles the possibilities of using eye and head movements as well as voice input as these alternative modes of communication. One part of this project is devoted to find possible interaction techniques when navigating in a computer interface with movements of the eye or the head. The result of this part is four different controls of an interface, adapted to suit this kind of navigation, combined together in a demo application. Another part of the project is devoted to the development of an application, with voice control as primary input method.

The purpose with this study is that examine if the contingency factors as sort of market and competition can affect the companies, which means of control they apply..

As a part of the fight against the global warming the energy production needs to be more efficient and redirected towards sustainable options. One alternative is cogeneration, which means that electricity and heat is produced in one plant. The purpose with this survey is to examine if there are any commercial available combined heat and power techniques, based on combustion of solid moist biomass, which are suitable to small-scale applications. The technique must be able to produce between 2 and 10 MW thermal and the heat demand is a Swedish district-heating system. When already published reports had been studied, the Organic Rankine Cycle (ORC) was chosen as the most suitable technique.

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.

Occupational stress and the use of alcohol to reduce stress are both separately common in our society. A few researchers have combined the two factors.The aim of this essay was to obtain an increased understanding of how male and female managers estimate their alcohol habits in relation to their occupational stress.We have interviewed nine managers who work at a social services department in Scania. Our main theories were the theory of psychosocial work environment of Lazarus, Karaseks demand/control model, epidemiology- and cultural perspective.Our results were;· Psychosocial work environment contributes to if the interviewed people experienced stress at work.· The grade of control has great influence if the interviewed people experience stress.· There weren't any correlation between stress and increased consumption of alcohol..

The purpose of this thesis is to investigate if there are any differences regarding syntactic complexity in written language between persons with (phonologically based) reading and writing difficulties and a control group. Earlier research has pointed to such a difference, indicating that texts written by subjects with reading and writing difficulties display a lower grade of syntactic complexity than text written by control groups.Two texts each from 48 subjects (24 from each category) were collected. The subjects were divided in two age groups, one consisting of 15-year-olds and the other of university students (adults in various ages). The subjects were selected through a word decoding test and a spelling test, where the lowest performing formed the group of reading and writing difficulties and the highest performing formed the control groups. All subjects had Swedish as their mother tongue.The syntactic aspects studied were number of words per syntactic sentence (Sw.

Detta examensarbete är utfört på Saab Training Systems AB i Huskvarna. Saab Training Systems utvecklar, tillverkar och säljer kompletta militära träningssystem.Syftet med arbetet var att minska ledtiderna, då korta leveranstider blir ett allt viktigare konkurrensmedel. Arbetet innebar en kartläggning av nuvarande reserv- och reparationsflöde samt att identifiera problem och komma fram till förbättringsförslag.Vidare har vi studerat reservdelslagrets lagernivå och dess kapitalbindning.Arbetet genomfördes med hjälp av intervjuer med berörd personal, observationer, enkätundersökning samt statistiska studier. Vi har även arbetat med Supply Chain Operations Reference Model som är en öppen referensmodell med vars hjälp man kan kartlägga, förändra och optimera sin verksamhet.Saab Training Systems har som mål att ledtiderna för reservdelsflödet och reparationsflödet skall vara 14 dagar, men i själva verket är det inte så. Dessa ledtider är idag längre, hur långa är dock oklart.De långa ledtiderna beror främst på att i flödena förekommer det mycket passiv tid.

During the last years the need for real-time database services has increased due to the growing number of data-intensive applications needing to enforce real-time constraints. The COMponent-based Embedded real-Time database (COMET) is a real-time database developed to meet these demands. COMET is developed using the AspeCtual COmponent-based Real-time system Development (ACCORD) design method, and consists of a number of components and aspects, which can be composed into a number of different configurations depending on system demands, e.g., Quality of Service (QoS) management can be used in unpredictable environments. In embedded systems with requirementson high up-time it may not be possible to temporarily shut down the system for reconfiguration. Instead it is desirable to enable dynamic reconfiguration of the system, exchanging components during run-time.

Examensarbete 20p Företagsekonomi Tekonomprogrammet vid Örebro Universitet ESI VT 2007Titel: -Order, var god dröj! - En studie i ledtidsanalys av ett TQM-företag utifrån ett SCM perspektiv.Författare: Pär Alfredson, Mikael Eriksson, Jonas HellmanHandledare: Leif SannerExaminator: Detlef QuastBakgrund Marknader skapar ett behov av kortare ledtider och mer effektiva leveranser när konkurrensen ökar. Utifrån denna verklighet har PartnerTech fått incitament från deras största kund att de vill förkorta den totala ledtiden på leveranser. När materialet som används i produktionen är metall som det i det här fallet så försvåras arbetet med ledtidsförkortning då efterfrågan idag är större än utbudet på den marknaden.Syfte Att i en fallstudie kartlägga och analysera företagets problematik med långa ledtider för produkt AT4CS.Metod Studien har en deduktiv forskningsansats där vi utifrån teorin undersöker vårt fallföretag. Vi har använt oss av både kvalitativ och kvantitativ data som egenhändigt samlats in men också sekundärdata. Vi har avgränsat oss till PartnerTech i Karlskoga och en av deras produkter.Teori I studien har vi använt oss av tre olika teorier, Total Quality Management, Supply Chain Management och Supply Chain Risk Management.Slutsats Den aktivitet som tveklöst står för den största andelen av den totala ledtiden är materialanskaffning.

De senaste åren har konkurrensen inom textilbranschen ökat avsevärt. Produkter på modemarknaden är fler. Den förändrade efterfrågan ifrån kunder innebär att kunden kräver nyheter oftare och det har lett till snabba trendväxlingar. Ledtider måste kortas om modeföretag ska vara beredda på de snabba trendväxlingarna. De korta ledtiderna ställer krav på effektivitet och flexibilitet i företagens processer.

Nowadays the world of football has become more commercial than before. As a result of this the clubs' financial status is getting more and more important. Therefore the UEFA has given the national federations a specific task to make sure that the clubs from each country follow certain standards of maintaining the football credibility. The Swedish federation has decided that the Swedish clubs must follow the so-called ?elitlicensen?.

The application of performance-based pay system among enterprises is becoming more frequent. Performance-based pay systems is used by organizations in hope of increasing productivity and have become more flexible. Employees may perceive the performance-based salary as a motivator or a threat depending on lifesituation and personality. At a perceived threat, the employee may become stressed. Work-related stress has become a serious social problem that can have consequences for both companies and individuals.

Logistik och Supply Chain Management som koncept har fått en ökad uppmärksamhet de senaste åren. Ett föråldrat synsätt på organisationen som en samling vertikala enheter som fungerar autonomt byts ut mot en vision om en flödesorganisation där ett helhetsgrepp om verksamheten och djupare samarbeten med leverantörer och kunder står i fokus. Ökade krav på konkurrenskraft genom effektivisering ställer nya ökade krav på en fungerande planering och styrning av varuflöden och där kan så kallade avancerade planeringssystem (APS) fungera som ett stöd och hjälpmedel. APS för produktions- och distributionsplanering är fortfarande ett nytt och relativt oprövat beslutsstödssystem. De senaste åren har företag som utvecklar affärssystem även börjat utveckla och sälja så kallade APS-moduler som genom sofistikerade matematiska algoritmer och optimeringsfunktionalitet kan stödja styrning och planering av komplexa system såsom försörjningskedjor.

A vehicle that carries a person sitting in a wheelchair has been rebuilt. The original vehicle was provided with a petrol engine, hydrostatic drive and a mechanical steering rod, making it noisy and hard to maneuver. The purpose with this project was to convert the vehicle to make it more environmental and easier to drive.A new design has been proposed where an electrical drive has replaced the noisy combustion engine and an electrical motor with joystick control has replaced the manual steering.The project was divided into two parts. One mechanical part where the construction of the drive and steering were to be decided. The other part involved programming the microprocessor and implementation of all the necessary electrical for the control system of the vehicle.
