The company Sound Precision has developed a new Line Array loudspeaker system (VHA-40). When using this system, their customers need computer aid to get the best possible sound-quality and control of sound levels for the whole audience. The aim of this thesis is to develop a truly useful sound quality simulator for the VHA-40. The system will help the sound engineers to position the loudspeakers for optimal sound by simulating loudspeaker configurations and visualizing the resulting sound quality and quantity. To solve this a human-centered design (HCD) approach is taken to implement a system that is truly useful for the users, meaning that they will use it more and hence deliver better sound for the audience.

This essay presents and discusses a study that was performed in a multicultural school, where the teachers, since August 2004, have obtained internal training in how to work with language development. The objective with this essay is to investigate how the connection between language development and the development of knowledge can be understood and apprehended by teachers working in this school, and furthermore, to show how a language developing way of work can be accomplished in the teachers daily work.Moreover, I have studied which objectives and strategies, the three language developers in charge of the training of the teachers, have concerning this work, furthermore I have looked into if these objectives and strategies differ from what the teachers understand and practically perform.Pauline Gibbons book, Stärk språket, stärk lärandet (2006), has become a base for this school?s work when it comes to language development. Gibbons presents theories and practical exercises which have their origin from Vygotskij, Halliday and Cummins. Their theories have also become my theoretical base in this study.I have made qualitative interviews with four teachers working in this school, and with one of the language developers.

Earlier studies shows that democracy within the preschool is an important and on-going work, but could implicate certain consequences. For example that goals regarding democracy and influence in the preschool, rarely is done in practice but instead remains just words on a paper. It could also mean that the pedagogues lack education and knowledge within the area, but also how they react to the influence of children. Preschool is expected to be a place for all children, no matter what luggage the child is carrying. The luggage is filled with the life experience, the personality and in this case the needs that the child has. The needs could be anything from nearness to physical and psychological disorders that requires more pedagogical attention.

In this project we have used the theory of analytical mechanics to derive equations of motion for complex mechanical systems in order to study their behaviour over time. Even if the theory provides powerful tools to tackle tough problems which would be very hard to solve by methods of Newtonian mechanics, you are still relatively limited without running any computer simulations. One realises that in a faster rate it will be an incredibly difficult task to find an analytical solution when the degrees of freedom increases. Even if one would succeed to derive the equations, one still has to solve them to get the information of the systems behavior. Of experience one knows that the equations in general are nonlinear and hence must be integrated numericaly.

The care for the elderly in the municipalities has recently seen the need for a formalized system for quality assurance. Under increasing demands for monetary efficiency while bound by law to retain acceptable standards in health care, there is need for efficient and at the same time quality-assured management. The municipalities often solve this puzzle by introducing systems and standards influenced by theory-clusters such as NPM (New Public Management), TQM (Total Quality Management) or other quality management theories.This essay focuses on how the public administration in the municipalities defines quality and designs and implements system for formalized quality assurance. Our basic view of organizations is institutionalist and our theoretical framework includes theories about quality, NPM and TQM..

The development of IT systems is usually accomplished by some form of system development methodology. It can be performed as the waterfall method, where each phase is completed before the next begins. One of the reasons to follow a development methodology is that the process is more structured, faster and that the product will have higher quality. One risk of not using a system development approach is that the code can be unstructured and difficult to maintain.This paper describes an alternative method in which the development occurred without the use of any system development methodology. This has been possible because there was a clear goal of the program that should be developed.

To be able to compete on the market environmental Management System has become an important part of operations work. However, many companies still haven?t implemented an environmental management systems due to lack of time and the high costs. One of the companies with this problem is Falu Bildemontering. Their goal is to accredited according to the ISO 14 001 certificate.

Bilingualism and multilingualism have always existed in Sweden. Preschool teachers must provide a stimulating pedagogical environment adapted to bilingual children.The purpose of this examination is to study the perspective of the preschool teachers and their knowledge regarding bilingual and multilingual children. Their knowledge will be examined related to their language experiences. I hope to find similarities and dissimilarities in the preschool teachers? opinions concerning teaching and learning what they actually do when they are teaching.My study is based on qualitative method, based on interviews and repeated observations.

Studies among parents of children with disabilities have shown that they experience a higher level of parenting stress as well as a lower degree of wellbeing, compared to parents of children without disabilities. However, there is a need to further explore parents? experience on this matter within a Swedish context. The aim of the current study was to examine how parents of preschool children, with and without disabilities, in Västerbotten, experience the impact of their child. A sample of 67 parents of children with disabilities and 134 parents of children without disabilities took part in the questionnaire study.

Energy costs are high nowadays and that is the reason why the energy consumption needs to become as small as possible in most of the companies. To accomplish the small energy usage one needs to map the energy flows, study them and monitor them. One method that can be used for this is energy balance calculation. The method gives an opportunity to separate different energy flows and see where each flow is heading. There is also another method which is more advanced than energy balance calculation.

There exist several known methods for calculation of radio coverage for ground-based systems. As far as we know there are no equivalent methods for the case of flying platforms when the altitudes and speeds are significantly different to those of ground-based systems. This thesis describes the theoretical concepts behind calculations of radio coverage for flying platforms. An investigation is made to sort out what is important and possible to employ in a model for simulations. A method is described and implemented in a program for evaluation of flying radio systems.

The purpose of this study is to describe and analyze how auditors are affected by quality controls and if audit practice changes because of quality controls. To fulfill the purpose of this study there has been interviews made with five auditors. The conclusion by this study is that the interviewed auditors work practices are affected by quality controls and that the extent and effect depends on the auditor and the office that the auditor works in. The auditors who worked as quality reviewers at the agencies where they are employed at, we felt that they were more secured in the response towards quality controls. This may be because they are quality reviewers themselves and they know what the quality control requires and what must be met to be approved.

AbstractThis text deals with one of the preschool everyday routine chores, and the phenomenon I have chosen to investigate is the hallway situation. The purpose of the study was to see if the hallway situation offers good communicative interactions between children and teachers, and investigate if the teachers use special strategies to make the hallway situation work. The method of this study was survey, qualitative interviews and observations. The three methods have deliberately been selected to best suite and reply to the different issues.Today?s groups of children in preschool are very big, and some of the preschools are not adapted to these large groups of children that we have today.

The aim of this study is to investigate into the use of discussions in the classroom to help the pupils develop a deeper understanding of mathematical concepts and operations. The empirical data contain interviews with two teachers and observations from their lessons. The purpose of the interviews was to find out what importance the teachers ascribed to the ability of their pupils to talk about mathematics, and how they organised their classes to encourage mathematical discussions. With the observations, I was able to see the interaction in the classroom and hear discussions between the teacher and the pupils, as well as between the pupils themselves.The interviewed teachers proved to share my own belief in the results of researchers like Malmer (1999) and Löwing (2006) about the importance of verbal discussion, argumentation and reflection during mathematics classes. But convictions derived from the research of others are one thing, the practical application of the wisdom in the classroom another.

In the context of world globalization, Sweden has today become a multicultural society, where many different cultures, religions, values and approaches are trying to co-exist. When the Swedish government's integration policy was put into effect, one sought to open the way for a more peaceful coexistence between majority and minority people. The intention was that everyone, through mutual interaction, would learn to come together and learn to respect each other's differences. It was suggested that an intercultural approach should permeate all education, including preschool activity. There are particular guidelines for a culture and tradition promotion work within the preschool in the new revised curriculum (Lpfö 98, rev.
