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.

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++.

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.

GPS is perhaps the future in agriculture. The next years will show it but the precision becomes only better and better and the number of users becomes only more and more. This work shows experiences from today's users and how the profitability can be improved on a farm with normal plant cultivation. The aim is to show how big the actual advantage can be to have a GPS and how good precision there is with the equipment. John Deere and Trimble are the big producers of GPS equipment to the agriculture.

The development of applications for mobile devices has exploded in recent times. This has also led to the introduction of several new mobile operating systems. To streamline application development for multiple platforms, techniques have been developed to be able to reuse the same application regardless of the operating system. If the same application can be used on multiple platforms it will save both a lot of time and money. Today there are three types of techniques to develop an application; web, hybrid and native application, where the latter is specific to the operating system it has been developed to.

Today, maintenance is a big part of the daily life on board ships. It is also one of the bigger expenses a shipping company has and without any loss of quality tries to run as economically advantageous as possible. In the hunt for economical savings the shore-based industry has subsequently applied the use of condition based maintenance, CBM, were a component is maintained according to its actual state. This leads to a reduction of maintenance costs since no parts are unnecessarily replaced. However, within the maritime sector a periodical maintenance is still the most commonly used maintenance system.The purpose of this paper is to chart the factors that are the reason for the low implementation of CBM on board the Swedish merchant fleet's ships.

Background: An accountant is supposed to secure that the information from a company is true and fair. Recently consulting, or giving advice, has grown to be a major part of an accountants daily work particularly in smaller companies which may have insufficient financial competence themselves.

The purpose of this essay is to describe how probation service officers regard their professional role and their liberty of action within the motivational treatment program, MIK, and the probation organization. To answer the purpose three questions were formulated: 1) Does the probation service organization affect the individual discretion for the probation service officers, and in that case how? 2) Does the motivational treatment program, MIK, influence the probation officers? professionalism and their professional role? 3) What advantages and disadvantages do the probation service officers consider MIK being related to? The method conducted in the study was interviews with five probation service officers in Stockholm. The interviews were combined with a theoretical framework based on themes as organization, professional role, professionalism and motivation. The result showed that probation officers consider themselves to have a relatively high discretion within their work.

This study deals with teachers ideas about the physical environment of a mobile preschool and how it affects children?s learning. The essay describes how the preschool bus is decorated and how a normal day works in the mobile bus. The survey was based on the following questions:Are there disadvantages and advantages in terms of physical environment in the mobile preschool from an educator based perspective?What are the teacher?s thoughts about the impact on children?s learning in terms of the physical environment on the bus?Summary: To answer my questions I have participated in activities during the day and I have used the interviews to find out the teachers thoughts.

This study aims to explore managers? experiences and perceived conditions for exercising leadership in both hybrid and physical work environments. The empirical material consists of eleven semi-structured interviews and four policy documents. The sample includes eleven managers, of whom six work in a physical environment and five in a hybrid setting. The study follows an inductive approach, where the interviews were first collected and later analyzed by identifying patterns and connecting them to theories on different leadership styles, monitoring, and trust.

The study is based on the pragmatic question whether one can apply the theoretical perspectives priming, experience space and relationship marketing in a practical context. The authors visualize how these concepts appear practical and what advantages and disadvantages can be discerned in the particular case of HV71. The method used is a hypothetico-deductive approach, which is not entirely conventional in the humanistic and social scientific context. Consequently, it has been proven to be particularly suitable as it could expose the theoretical perspectives for a difficult scientific test.The result of the study demonstrated that a marketer could benefit from using the theoretical perspectives when exercising the profession. It also showed that the object of study applied these perspectives.

Background: The trademark is something that surrounds us almost all the time wherever we are. Studies show that brands are becoming increasingly more and more important and that it is important to have a strong trademark. This may be a reason for acquisitions. A business is carried out for various reasons, but usually it is to gain market shares or to get advantages in the market, such as a trademark can help with. A contributory effect on the market can be customer loyalty to the trademark.
