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 purpose of this thesis was to create a saw pattern program for the sawmill industry. I have chosen to focus on the module that describes the shrinking on the wood. There are several theories about how the wood deforms by shrinking. Several hypotheses were simulated in the program and after testing them I decided to use only one of them (hypothesis C). The program is written in Visual Basic .NET and I choused that program language because it is easy to do changes in the layout. Another great advantage in Visual .Net is that you can mix different languages in the same program.

The purpose of this study is to examine and compare librarian profession with different professional theories. The intention is to describe how the librarian profession meets the different professional criteria and to what extent the librarian profession can be said to be professional in expertise, service and autonomy. Nolin?s modern theory provides an opportunity to analyze occupational groups based on professionalized basic concepts. The analysis of relevant material showed that the librarian is a service profession with high skills, but does not hold a high degree of autonomy.

Maize for silage has been used as fodder in different parts of the world for a long time and has recently become more common also in Sweden. Our cold climate has been a problem as maize is very sensitive to low temperatures and frost. With new varieties and better techniques for cultivation it is now possible to grow maize in the southern and middle parts of Sweden. As for the north of Sweden the length of the cultivation season is a limiting factor as there are too few days with temperatures of over +10 ºC. Maize is well suited for silage making but oxygen-free conditions are required.

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.

This study focuses on nationalism in Central and Eastern Europe. Anchored in theories that this region historically has been characterized by a nationalism that is based on the ethnic group rather than on liberal or civic concepts, it is the purpose of this study to explore whether these theories still apply in recent times when the region has been liberalized, for example manifested in the entry to the European Union. The research question has been tested through analysis of the constitutions of a number of Central and Eastern European countries in order to investigate what type of nationalism that the states have codified in their basic political documents. The results show that some of the states give expression to the historical ethnic nationalism in their constitutions, which indicates that the theories still are relevant..

This essay examines teaching in source criticism in upper secondary school history education. Two questions are to be answered: 1. What are the conditions like for teaching source criticism? 2. What opportunities for further development in teaching source criticism are there? In order to set a standard for what knowledge and skills in source criticism the students need, I design a four step model for good source criticism based on the historical science.

This essay will analyse how Asperger?s syndrome and autism spectrum disorder is made in two municipal high schools.

The subject singing in elementary school changed its name to music in 1955 and with the name change followed a change in the content of the topic. In my study, I examine the perspective of how song as a subjekt has changed in the basic school curriculum texts. As a complement to text analysis, I used interviews in which two music teachers with long service in primary school were interviewed. My survey shows that there has been a clear change of the contents of concept song from being a pure skill where the aim was the vocal line benefits in different contexts and is today a vocal expression that can be embodied in many different ways. Curriculum texts have not been crucial to the changing content of the concept song.

Marketing in a business-to-business environment differs from its counterpart in the business-to-consumer market. Where the latter focuses on customer satisfaction, the former is all about value. This value creates loyalty between seller and buyer. Creating loyalty is becoming more and more important in the media planning industry as fierce competition reduces profit margins. Value is created through selling what a client wants at an acceptable price.

There are some key elements which distinguish a general operating system, such as Linux, from a Real Time operating system, such as OSE. The later belongs to the category of soft Real Time systems while Linux is a general operating system, with significantly improved real time properties after version 2.6. These improvements make it interesting to compare the two systems.When comparing two operating systems, there are a number of issues which have to be considered. One way to measure the performance of the systems is by studying the time consumption for the same functionality and hardware.During the study, the items that appeared as the most important for the performance of the systems, were: process primitives, system primitives, interprocess communication, context switches and interrupt latency.This work demonstrates that it is possible and reasonable to do performance testing on two different operating systems. The implemented tests cover a number of basic functionalities, which appeared to be the most crucial ones for the performance of the systems..

How do we match our education with the needs of the construction line of business and the requirementsof the Swedish National Agency for education? Is there something that we have to change?In this study I have asked our former students about their opinion of our education and I have also asked them to give me their view on what a good teacher is like. I have been able to benefit a lot from their answers in my efforts to be that good teacher. This survey took place at Facebook.The answers showed that we carry on a piece of solid workmanship. But you can always improve, try harder.
