In inhalation anesthesia life-support systems are used to provide gases to the patient and to monitor important parameters. These systems are used in dynamic and stressful situations where the information-load on the operators often is significant. This thesis presents a design concept of an anesthetic system. The design goal has been to keep the information-load on the operator low with the objective to minimize confusion and error.A number of contextual inquiries were made in the operating room during surgery at four hospitals in Sweden. The goal was to understand the actual use-situations when anesthetic systems are employed.

This thesis is a process oriented case-study. The studied case is a interactiondesignassignment of a databasevisualisation and the process. The goalis to do this according to the ways of a screenwriter.When the computers spread from the military and university's into homes all around the world the computers and the programs had to becomeeasier for the users to understand and use. User interfacedesign became more and more important and companies like Apple put a lot of resources intothe designprocess. This quite new and evolving area of research, interactiondesign, has been forced to search for methods in other areas like lm, gamedesign, psychology and behavioural science.

The purpose of this paper is to describe how librarians andusers think of electronic books in libraries. My questions are:-What are electronic books, and how do they work?-How has electronic books been implemented by librariansin the libraries and on the libraries? websites?-How do users describe their view of electronic books?-How do the librarians and users think of electronic book inthe future?To be able to answer these questions I have studied relevantliterature, made qualitative interviews with two librarians attwo similar libraries and I had dialogues with several usersElectronic books were introduced 2002 at the two libraries.In the beginning the libraries made different types ofmarketing, but today they only have the website withinformation. Their purpose was to try this out and offer theusers a new media. So far, there are few users who borrowthese books, and maybe it depends on technical conditions.According to the dialogues I had, most of the users have noidea what electronic books are.

Focus has been placed upon the advantages and disadvantages that could follow in the working method.The method used in this essay is qualitative in order to answer all the questions that arise along the way, and in order to use this method in interviews. The interviews that has taken place has been with five class teachers that are currently teaching at a elementary school between the years of 1-5. The purpose of this study has been answered by using its literature and the qualitative method with the class teachers.The results of the research show that teachers express gratitude towards the method in use for mathematics studies.

Researchers and practitioners have recognized the need for ?transforming? every policy of the company into a competitive advantage tool. Thus, both the pricing approach and the supply chain practices of the firm have emerged as an important determinant of success. In this study, however, we are not only interested in these two aspects, but also in a third one-namely cultural conflicts as an obstacle and challenge. The interaction of the tree factors is extensively presented against the backdrop of Skanska and four of their closest Polish suppliers.

Open source software has recently been discussed, not least in media as a revolution in IT. A number of advantages have been listed in changing proprietary software into open source software. Examples of such pros are no expenses for license fees and improved efficiency. In spite of this, few users have made this change. One of the reasons is a distrust of the quality in open source software.

In today's changing environment, an increasing number of companies are realizing thebenefits of analyzing business information and thereby stay competitive. By making use ofdecision support systems, known as Business Intelligence (BI), organizations are expected tocollect and process business data and thus get more out of their business.Nowadays it is not enough for organizations to have access to corporate data inside officewalls, they must also be able to bring the information "on the go", which has been thefoundation for the progress of mobile BI solutions. As the mobility increases and thecorporate data leaves the office, new risks arise, which is one reason as to why manycompanies hesitate at the idea of introducing mobile BI solutions.In this paper we explore two security aspects in the area of mobile BI solutions. Our researchquestion is as follows: How does security aspects affect a company's decision to acquiremobile BI solutions? The survey was conducted through interviews in cooperation with thefirm Optivasys, exclusively dedicated to the BI solution QlikView.A significant part of the theory we studied describes security as critical; however, ourresearch suggests a solution on how companies can manage the security aspects.

This paper is about the new programming language from Microsoft, C# (See Sharp) and the .NET Framework. They are still in beta-version, but will be released on the market in February 2002. This paper presents C#, not in detail but the characteristics that distinguish the language. A comparison is done with C++ and Java, since C# is most resembling to these languages. Both C# and Java have been developed from the mother- language C++.

A reform of higher education in Sweden in 1993 led to stiffer competitive climate among educational institutions. The reform meant that educational institutions now had the opportunity to plan their curriculum autonomously. Prior to the reform educational planning was restricted to the Swedish government. The new rules spelled a greater opportunity for educational institutions to profile themselves based on their educational offerings. The higher degree of competition means that marketing becomes increasingly important when recruiting new students.

This essay discusses the legal and economic functions of the trademark and furthermore the degeneration of trademarks. These two concepts are strongly connected as the primary function of the trademark is the ability to separate the proprietor of the trademark?s product from the competitors´ products. The ability to separate is the basic condition for receiving legal protection. Through degeneration the trademark loses this ability to separate the product and becomes a generic term for the category of the product.

Relationship Marketing - will banks be able to handle higher consumer mobility in the private market?The purpose of this paper is to gain an understanding of the factors that affect customer loyalty to the bank. Consumer mobility will probably increase as a result of political changes and pressures on the private banking market to become more competitive. This study was carried out using semi-structured interviews and were transcribed and analyzed with the help of models and theories centered on relationship marketing. The theories describe loyalty, the customer lifecycle and relationships between customers and organizations.

This thesis is the result of the author?s interest in music and electronics, namely the design and manufacturing of a stereo sound system with an active crossover. In short it can be stated that an active crossover has many advantages over its traditional passive counterpart. The active design naturally results in a more complex system comprised of a multiple number of components. This report deals with the theoretical aspects of preamplifiers, crossovers and power amplifiers as well as power supply and control.

The purpose of this development project is to create a model for working with a high school project in Electrical and Energy Program. It should be conducted in a form like companies do according to the goals from The Swedish National Agency for Education. In order to fully perform this we use the concept of Young Entrepreneurship. The model is created according to the new conditions from The National Electrical Safety Board. There is now an exception saying that a student during education is released from the demand of employment that is the normal procedure where you are under supervision from a certified electrician. During the project there has been theoretical and practical examinations in order to clear out the advantages and disadvantages using this model, but also to examine whether it is useful in the future and to what extent it can be used. The result indicates that the model is useful and fulfills the goals from The Swedish National Agency for Education but that the model has its limitations and difficulties.

The task in this thesis is the steering of one of Saab Bofors Dynamics robots using Sliding Mode Control, a method they never used before. The robot constitutes a system which in addition to perturbations and uncertainties due to modeling imprecision, hold the difficulty of being highly time variant. In order to be able to keep required performance with uncertainties and modeling imprecision present, the use of robust control methods like Sliding Mode Control is necessary. SMC is based on the states of the system being forced to stay on or in the direct vicinity of a hyper plane in the state space which is chosen in a way that gives the system dynamics desired properties. Other advantages with sliding mode are reduced order dynamics on the switching surface and total insensitivity to some uncertainties and perturbations.
