This paper is partially a literature study of human error and interruptions and partially an investigation of pilots and Air Traffic Control. The aim of the investigation was to find out where interruptions occur and how to reduce or eliminate them. The objective of this paper was to investigate what type of interruptions pilots and ATC deals with and during which phases they occur. The paper has revealed that private pilots causes more interruptions for ATC personnel than commercial pilots. The cause for this is probably the less experienced private pilot and the fact that Swedish is used before English by private pilots in communication with ATC.

The objectives of this paper are to discuss experiences from in-service courses, INSET, in the new school subject Technology..

The aim of this essay was to investigate how teachers in the preschool class work with literacy. How do they justify the methods used to develop children's literacy abilities? I also wanted to know to what extent teachers enable multimodal approaches within written language practices. My study considers the impact teachers' professional identity has on working methods in the preschool class. I hope this essay will help teachers reflect on their learning approach. I gathered information by interviewing three preschool teachers and one compulsory school teacher for the early years working in three different preschool classes in three different schools.

In this thesis, a computer program that in a simple way can calculate the performance of control loops at the refinery Preemraff Lysekil has been created. The computer program has been adapted to the environment at Preemraff Lysekil. Theories for evaluation has been studied in aspect of reliability and of automatic implementation. The evaluation has been carried out from data collected directly from control loops at the refinery and from simulated control loops with implemented errors. Among the studied methods are Harris index and Stattin´s oscillation index.

The thesis demonstrates protection solutions that can be suitable for a camp during internationalmissions in order to resist complex threats. The threats could consist of small arms, machineguns,RPG 7, anti armour missiles, mortar, artillery, HPM-weapons, car bombs, biological and chemicalweapons as well as sabotage and theft. It?s not the technology itself that makes the threat scenariocomplex it?s the way the opponent acts during the operations. The opponent acts usually incivilian clothes and therefore he is difficult to distinguish from other civilians.

Internet's entry into our home has changed our communication capabilities. As a result more and more services in the digital world are available. Besides e.g. shopping, gaming and general information, different social networks now offer preventive and therapeutic health-oriented services. When being asked by several young people, with whom I have been working in a clinical setting, to offer conversations over the Internet that enables both to see and to hear each other in real time, I decided to conduct a pilot study which is presented in this paper. The aim was to investigate the feasibility of offering supportive therapy using video calls over the Internet.

AbstractIT can facilitate communication among individuals and connect people across geographical distances. On the contrary, citizens of the society who do not use communication technologies to some extent might feel excluded from the information society. As elderly citizens are already in a vulnerable position for the digital divide, communication technology becomes an important tool for interacting with friends and family. The social situation of elderly, 60 years of age and older, is a topic of current interest since they are the fastest growing age group in the world today. Further, social interaction becomes more important among elderly since it has a positive effect on well- being.

The concept of the photographic truth has had a special status for almost 200 years. Yet with the emerge of digital technology and especially digital photography there has been a loss of the particular connection photography has had in reference to reality. The aim of this study is to see in what ways digitalization has affected the credibility of photography from the perspective of professionals in the field of photography. The digital technology that has enabled the large-scale manipulation of photographies is not, however, the main reason for the decreased credibility of photography. The ongoing discussion about the available possibilities concerning digital imagery and manipulation has had a far more powerful effect on the concept of the photographic truth.

The use of vision applications are growing and the demand for integration and connectivity with other industrial automation control devices is increasing. Some businesses that are using vision technology follow US Food and Drugs Administration (FDA) regulation concerning audit trail. This thesis investigates the possibility to use vision technology for counting objects, achieving connectivity and to follow FDAs audit trail regulation. A market survey has been used to select suitable hardware and software to be used in the design of an application that is able to count objects and that uses standard industrial network connection i.e. OPC data access and Microsoft?s .NET components over Ethernet.

Music today is a big part of a person's everyday life and can influence emotions as wellas initiative and motivation. This effect together with development in technology hasled to that music today is accessible and can be played from a large amount of differentkinds of products. This in turn has meant that the demand for smaller audio playbackdevices is greater than ever.The goal of this project is to develop a concept for energy-efficient speakers withwireless communication that has the ability to obtain and play high quality music. Thespeakers will use the latest available technology and at the same time, using digitalsignal processing, have a low environmental impact through high energy efficiencyand low power consumption. Parallel to this work a pilot study will be conducted tosee trends in listener preference of sound.The result achieves the goals pledged while power consumption in sleep mode is solow that they meet the demands of tomorrow.

This diploma work has been based on finding a solution to Hälsoteknikcentrum i Halland. The task was to design the wheels of a wheelchair gear, so they can put on and remove with a locking feature.I have sketched out the solution and drawn up in Catia v5, which will be handed over to health technology centers for accounting.  .

The aim of this thesis is to study a number of standards and theories, from the two research areas human-computer interaction and psychology, about how a graphical user interface (GUI) should be composed in order to facilitate interaction between humans and computers. Special emphasis is put on how the GUI should take into consideration the strengths and limitations of human cognition and perception. A study of three web catalogues shows how these theories appear when concretised. The following questions are answered in this thesis:What guidelines and styleguides can be found that specify the design of a user-friendly GUI?How do a few library catalogues on the web match a selection of these design principles?The guidelines are extracted from literature concerning human-computer interaction, psychology, automated library systems and web design.

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.

I den här rapporten beskrivs hur elever mellan åtta och tolv år upplever användningen av datorn och Internet i skolan. Genom att studera användningen av Internet med hjälp av intervjuer, deltagande observationer och informella samtal har författaren i den här rapporten valt att utifrån elevernas perspektiv beskriva deras situation. Utifrån den etnografiska studie och de konstruktionistiska teorier författaren gjort utnyttjas sedan erfarenheter från utbildningstiden för att försökta skapa ett koncept om hur ett framtida klassrum skulle kunna komma att se ut. Undersökningar har gjorts om hur information, kunskaper och erfarenheter utbyts i klassrummet och vilken betydelse det har för användningen av Internet. Men även hur elevernas själva utvecklas och skapar sig ett kritiskt tänkande och att lära sig sortera, för dem, relevant information. Jag har även studerat hur lärarens roll förändras och hur det påverkar undervisningskulturen.

The report analyses if some common problems can be avoided by using modern technology. As a reference system ?Fartygsrapporteringssystemet? is used. It is an n-tier web application built with modern technology at time, 2003-2004. The aim is to examine whether ASP.Net MVC, Windows Communication Foundation, Workflow Foundation and SQL Server 2005 Service Broker can be used to create an n-tier web application which also communicate with other systems and facilitate automated testing.
