The most common way to treat wastewater in Sweden today is by a combination of an activated sludge process and a chemical treatment. These processes are not very energy efficient and may not be the most environmentally friendly. That is why it is interesting to evaluate new alternative methods to see if they can be less harmful to the environment and help to a lower resource consumption. New techniques are tested in a pilot installation at Hammarby Sjöstad, Sjöstadsverket. To be able to evaluate these techniques in a wide perspective system analyses are conducted where different impacts can be considered, advantages and disadvantages in the systems.Five system structures for water treatment have been constructed in Matlab/Simulink in this study.

In the society of information that we live in the knowledge of computers and computer system will have a greater influence than we may think. Discrimination is no longer exclusively a term that indicates lesser understanding of different cultures, the discrimina-tion that is at hand will be between ?the have and the have-nots?.This study is about the strategic methods and considerations that is of importance for planning, organizing and finally implement the work with national computer based patient documentation. The strategic planning has been done over a period of time where different actors all had their share of influence. The cost seems to be endless since it has increased after the actual program, in this case, Cosmic from Cambio Healthcare, entered the scene of healthcare.

There are around 855 000 on-site sewage systems in Sweden and some 1 800 of these are located in the municipality of Sigtuna. The Sigtuna local authority has set the goal that all sewage systems with insufficient function should be improved before the end of year 2010. A malfunctioning on-site sewage system may cause three main problems: spreading of diseases, discharge of eutrophicating compounds and wastage of resources. The municipality strives to reduce these problems already at the stage of granting permits for installation of on site sanitation systems. The municipality has recently adopted new guidelines, which demands certain minimum reductions for different compounds. The guidelines also state that it is preferred that neighboring house-owners cooperate in jointly built and operated sewage systems and that the system should be able to recycle plant nutrients.

Blekinge Hospital suffers from a budget shortage of 100 million SEK, while the government now requires that hospitals will no longer be running a deficit. Blekinge Hospital will then use their limited resources to survive in the future and the activity must be enhanced in order to keep costs low without having to lay off personnel. The idea is that the organisation should be more efficient with a more efficient resource usage. Performance measurement systems are important tools for achieving the policies set out within an organization, measuring and evaluating performance is a way to see where improvements in efficiency may be necessary in the business. Balanced Scorecard (BSC) is one of several measuring systems, where the focus is on measuring non-financial performances.

As the volumes are entering the world of computer graphics the pure volume visualisation becomes a more important tool in for example research and medical applications. But the advance in haptics --- force feedback from the computer --- is behind. In volume haptics no equal to the proxy method so popular in surface haptics has yet emerged. Some implementations of volume haptics even use surfaces as intermediate representations so that surface haptics can be used.The intention of this work was to create natural feeling haptic feedback from volumetric density data using pure volume haptics. The haptic algorithm would be implemented in Reachin API for the Reachin Desktop Display, together with other parts to build up a usable volume visualisation environment.To achieve the feeling of stiffness and friction dependent on tissue type, a proxy based method was developed.

The purpose of this essay is to find an answer to whether the methodology used by the Naturskolan conduces to learning and also if the Naturskolan, as a method of its own, leads to an increased interest in natural science for the pupils participating in the classes at the Naturskolan.The method which has been used to reach the results of the study is a quantitative opinion poll. The results reached through the study has been compared to previous research in the subject. Deeper studies were made to examine however the interest of the pupils was influenced by their visit at the Naturskolan.The results of the study show an increase of interest in natural science after visiting the Naturskolan. It also shows that the teachers? interest in natural science and outdoor pedagogy has increased by the visit at the Naturskolan.Through this study we came to the conclusion that the Naturskolan is a good method to learning..

Libraries all over the world struggle against the threat of decreased funding and a lack of governmental interest. In countries with an under-developed library sector the interest from the government is often minimal or non-existent. Since the 80´s Sida, the Swedish International Development Cooperation Agency has contributed to the library development in Central America through the Royal Library of Sweden. Nicaragua was the first country to be counterpart in the project. For a period of eight weeks I have completed a field study in Nicaragua and visited the National Library Rubén Darío and public libraries in the country.

AbstractThis study deals with NTA in preschool and the purpose of the study is to find out how the NTA project works out in practice. In the empirical study I have used questionnaires as a research method (Trost2001). Questionnaires have been sent to preschool teachers in the whole of Sweden to get as good a selection as possible. The responses received have been processed and analyzed. The results are reported below.The majority of the teachers thought it worked well to work with the NTA.

This is a thesis on D-level. In a previous course, at our program Computer Science, we came up with an idea of how to improve/complement training for new employees who are situated in a stressful workplace at companies who are in a constant need of rehiring. We developed this concept and came up with an idea for a simulator that could train staff as well as relieve stress and tension for new employees. The idea matured and became a Serious Game simulator based on a dual-wield Wii-controlled PC-based simulator with Bluetooth support.The purpose of this paper is to produce a design concept for a simulator as well as conducting research on the topics: mental and physical learning abilities, psychomotor abilities, visual perception, hand-eye coordination, confidence, simulators and Serious Games. The conducted research will be the foundation for the design concept which will be implemented in our co-workers', Henrik Djerf & Daniel Gomez-Ortega, prototype.

The demand for food, feed, fibre and fuel has increased in Uganda over the past 50 years due to population growth. Recurring extreme climate events such as drought and flooding, in combination with large-scale land degradation, have led to declining crop yields. Lack of equipment, money and socio-economic issues has contributed to low yields. However, the soils in Uganda have the potential to produce much higher yields than they do today. This study, which was carried out in April-June 2013 in Kkingo District, south-east Uganda, examined the effects of agroforestry on yield of cooking bananas in small-holder farming systems. Six farms practising agroforestry and six farms with no agroforestry, which were chosen in cooperation with the NGO Vi Agroforestry, were compared.

Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.

We live in a society that is constantly developing and where technology is getting a more major roll. The school is a very important part of our society and should therefore develop in pace with the surrounding society. Having this in our thoughts we decided that our purpose for this case study should be to study the importance of technology in a learning environment for seventh graders in a specific school. To be able to find this out, we have used constructivism and sociocultural perspective on learning. We have gathered our empirical data for the study through participant observations and a focus group interview.

BIM has been a trend in recent years when it comes to design and construction ofnew buildings. However, there has been less talk about what happens to BIM modelsafter the construction phase.This issue has been raised at the Forsmark construction documentation department.This thesis aims to look at how the information in a BIM model can be transferred tofacility management and GIS systems and thus add value, even after the constructionphase.Questions raises how such an exchange might look like and whether it is reliable.How should a claim be brought to planners for such an exchange to work.This thesis tested some of the most common methods for this kind of exchange ofinformation from BIM models to facility management and GIS. It was formats like IFC,Fi2xml and a database connectivity that was analyzed by a computer simulation of amodel provided by Forsmark. The model consisted of an existing office building atForsmark, modeled in Autodesk Revit.The results indicate that the formats tested require a precise plotting of the models.The loss of information that came to light in the simulation could be attributed tofailure modeling in Revit. Even such things as naming of areas must be consistent.

More frequent and intensified rainfalls are expected to occur due to climate change in the nearfuture. This together with a higher proportion of paved areas increases the pressure on today?sstorm water systems (Risinger, 2014; Boverket, 2013; Stahre, 2006). Traditional storm watersystems (i.e. underground pipe systems) have during last decades started to be questioned(Olshammar & Baresel, 2012).

To support uniform and fair assessment of Swedish students? English language competences, mandatory National tests are provided both for secondary and upper secondary education. The current thesis may be seen as a contribution to the further development and validation of these tests, with regard to the likely introduction of computerized testing methods. The aim is to gain further knowledge from current research in the field, to study and elucidate international experiences of implementation, and to gather and analyze feedback from students and teachers. Based on my findings, some tentative conclusions will be drawn, and recommendations made concerning future developments.
