This work aims to evaluate the possibility of using a graphical programming language to develop software for a digital signal processor. A fixed-point digital signal processor called Blackfin BF-537 is used for this. Instead of using conventional programming languages, like C or assembler, for software development the possibilities to use a graphical environment to fill the same purpose are examined. The development environment primarily used is NI LabVIEW, but also the use of Mathworks Matlab Simulink is investigated. A variety of programs consisting of various signal processing operations and utilities are developed using these development environments.

The title of the paper aims at a comment by one of the students during an interview. It reflects how most of the students experience the lunches in a specific school where the investigation is made. The question of pedagogical lunches has always interested me. Here I have used a method called the Grounded theory. I carried out a qualitative investigation with a number of methods such as interviews and participating observations.

Textiles are made in an unsustainable way and there is a need to find alternative ways and material to reduce the negative impacts on the environment, humans and animals. Problems like pollution, excessive water consumption and loss of soil fertility is a result of this lack of diversity. It is a necessity to find innovative alternatives in other fabrics due to the unsustainable use of cotton and polyester fibers. As in many other countries in the Western part of the world, in Sweden there is a rapid turnover and increased selling of clothes that result in increased textile waste. About 15 kilogram of textiles (net inflow) is consumed per person each year.

This essay deals with the issue of children and stress, and the impact that stress can have on children. The purpose has been to explore how I, in my role as teacher, can prevent children from developing stress in preschool, and how I can prevent stress to develop inside of my own department. My essay is structured as follows: First, I describe my practical work with children. Then I analyze some research literature on stress, and finally I reflect over what I have described earlier and try to connect the practical with the theoretical.In the practical part of this essay I describe the various events that I have observed during my work in preschool, where I have seen how stress can affect both children and teachers. Then I describe how the increasing size of children?s groups can create stress because of the noisy environment of the department.

It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).

Through previous studies during my education, I have experienced that chemical deicing road salt is a known problem, mainly in southern Sweden. Road salt causes damage to the environment and also damage to vehicles and structures such as bridges, etc. Road salt causes vehicles and steel constructions to rust, leading to increased costs for repairs of damage to structures. Road salt also causes damage to the plants and the economy to suffer, when plant material and soil needs to be replaced. In order to get closer to a solution, I put up three questions.

This graduate thesis takes its hold in an idea that many values, in cultural heritage environments, other than the onesthat can be seen with the eyes are as important for the experience of the environment as the visual ones; however theenvironments are usually defined by values that can be experienced visually!Interviews were held with four visually impaired persons. This to get a better understanding for how big part othersense modalities play in the experience of the cultural heritage environments. Questions were asked about what thevisually impaired especially value in cultural heritage environments and what is of value for preservation. Also whatcan be done to make the environments more impressive for them, how they experience the material part of theheritage, architecture, shape and color and with what senses they primarily remember. Furthermore the thesis aims todraw attention to how value definitions made by the conservation field affects the experience of the environmentsand therefore the accessibility for visually impaired.

The aim of the study was to map the extent of Fe, Cu, Pb, As, Zn and S contamination in the area surrounding the Nasa silver mine. The mine operated between 1635 and 1810 with some prospecting performed in 1889, and has become infamous for the gruesome ways that the indigenous people were treated during the early years of operation. This study tested three hypotheses through a geochemical survey: 1) sulfide oxidation is still active in the abandoned mine, 2) the soil downslope of the mine is contaminated by mine drainage, and 3) the stream downslope of the mine is affected in the same way. All three hypotheses were valid, as the results showed that still, >200 years after mining operations ceased, signs of the historical mining are clearly visible in the surrounding environment. Acidic conditions were discovered in surface waters close to the waste rock piles, which indicates active sulfide oxidation.

The company Sol & Energiteknik wanted to examine the possibility to make a standardhouse totally energy independent. Based upon this I have, during the spring of 2007,examined the possibilities available at the market today through litterature studies, contactwith several companies and reading reports at the internet.The first thing to examine has been to determine the energy consumption for a standardhouse, and find out if there are better technologies to be used for energy conservation.My conclusion in this matter is that there are possibilities today for building a house moreenergy efficient.When I had reached the point at which my design for the house was decided, I also hadto choose the different products to use to produce energy as well as to store that energy.To produce heat and electricity to the house I decided to use a wind turbine and a solarwater heater.The most difficult part of designing a house that is energy independent is that theproduced energy must be stored somehow. Storing the heat is relatively easy beacuse theheat can be stored in a large water tank. The electricity is a bigger problem beacuse itmust be stored in batteries, which today are too expensive to be used in a standard house.In the future producing and storing hydrogen might be used to produce electricity, buttoday that technology is both expensive and not tested enough.My final conclusion is that a standard house can not be built to be totally energyindependent today, unless it is very expensive to connect the house to the electricitynetwork. As an alternative solution I came up with a proposal for a house which isconnected to the electricity network and have some amount of own produced energy.This house prooved to be a good investment if you choose to build it today, and it couldbe a very good investment in the long run beacuse energy prices increase every year..

In Sweden, grass is the single largest crop grown. Nearly 1 000 000 Ha grows on the fields, this is primarily used as feed for livestock. To get a good seed, you need to handle the crop carefully from planting to delivery. The part that I have been interested in, is how to dry the harvested seed with out destroying the growth in the small seed. This is very easily done if you aren?t careful during the drying period.

Title: GMO Food ProductsThe issue of marketing and selling them in Europe - A Business and Legal Perspective.Author: Shane KingSupervisors: Anneli Carlsson and Ewa RabinowiczProblemThe European Unions regulations in regard to GMO?s and the approval process for both release into the environment, and onto the market, has been under fire by the USA along with Canada and Argentina. The WTO has ruled on this issue in favour of USA et al.The problem that was identified was in regard to consumer opinion in the EU. How could the EU meet its numerous international trade obligations while at the same time meetingthe needs of the citizens of the Union? Added to that was the issue of whether or not the?EU? perspective was indeed an EU perspective or rather the perspective of a fewMember States.

Since a couple of decades the community of Jönköping has worked out an urban vision of how the city should be appropriated expanded. The prospect extends to around year 2040 and deals with the area south of lake Munksjön in Jönköping, Sweden. Today there is a proposal of how this would look like and what main public functions that should be located there. One issue in the so-called urban vision 2.0 indicates a congressional building. This report describes how such an object can be designed according to the urban vision conditions.The work is focused on three main themes;* Architectural concept and a modern form of expression.* A functional attractive congress building in a new planned town centre.* General concept of a realistic structure system that meet the spatial and architectural possibilities.Various concepts in the meeting industry and in the architecture field are identified in order to understand the concepts and ideas with today´s congress buildings.

Man spends most part of the day at work and is therefore influenced by it?s ambience. That?s why it?s important that the environment at work is health promoting and can function as a supportive environment. The purpose of this study was to describe job satisfaction among employees and to analyse a possible connection between job satisfaction and employees experiences of SOC.

Several studies has identified the locker room experience as a potential deterrent for participation in physical education. Both psychological and physical issues arise due to several factors. Psychological issues include different kinds of verbal and physical violations, comparisons between pupils, feeling of vulnerability along with a stressful schedule. The physical environment can contribute to negative experience for pupils in terms of filthy premises and cold showers. These factors may contribute to higher absentee rates in physical education.

Previous research shows that Swedish teenagers? reading of fiction have decreased during the last decade (Skolverket 2006). As future librarians we found ourselves asking why, and an interest to look into this was triggered. The purpose of this Bachelor thesis is therefore to examine why teenagers? reading of fiction is decreasing. Focus lies on students? perception of their own reading, both inside and outside the school environment.
