This report discusses questions concerning wear on forest roads. The purpose of the work is to investigate if the wear on the roads will decrease when the speed limit gets lower for the trucks that transport the wood. A normal forest road, class B, was used in the study. In total 5000 m3f timber was transported on the road. Data about the road was measured with a profilograph car before and after the timber transport.

The Swedish curriculum says that the education will adapt and take notice of every child?s individual condition and needs. Every child has the right to development, to feel the happiness of growing and to experience satisfaction of making progress and overcome difficulties. In every class it is often children who need adapted physical education. The earlier these children can get support and practice, the bigger the chance is that they will catch up.

The purpose of this study is to show the importance of task texts for students in grades 5 when solving mathematical problems. It was conducted in a class 5 (where the children are 11 years old). The pupils were assigned two different tests with mathematical problems; one where the problems were described in text and one where the problems were presented with numbers and mathematical signs. Previously done research, done on bilingual children, (Bernardo, 2002) shows that pupils tend to do better on mathematical tests when no text is presented. My research supports that theory even though the correlation is not that strong.

The purpose of this thesis was to determine what materials should be used when creating a stimulating garden for intellectually handicapped people and whether there are materials that are better than others to use in this kind of environment. How the materials preferably can be used and how the environment should be designed to satisfy the need of each individual will also be discussed. Seriously intellectually handicapped people have the same level of intelligence as a normal 0-2 year old child. It is important to point out that these individuals can not be compared to a normal child in other aspects than the level of abstract thinking and perception of reality. As the grown up intellectually handicapped people have remained a lot longer on this stage of intelligence they have got more experience. (Kylén 1981) It is important with a lot of different experiences for the brain to develop normally, which implies the use of many different materials to achieve the best stimulation (Kylén 1981).

Invoxicated is an interactive play sculpture where children can explore the wonderful and playful opportunities of sound. Talk into one end of the sculpture, and the sound will travel through the sculpture and come out in the other end. On its way, the sound gets distorted by a number of sound effects. By bending the sculpture?s body, and pressing the sculpture?s buttons, the sound effects gets altered in real time.

Study objects: Three different productions companies which the authors have chosen to be anonymous. Purpose: The purpose with this study is to examine why production companies choose to use 3D-animations in television commercials, and what different kind of aspects affects their decisions. Theoretical: The theoretical chapter reviews the history of 3D-animation andtelevision commercials and other fields that will be relevant laterin the analysis and discussion. Method: A case study has been made on three different companies, two of the companies are active in post-production and the other one is active in the consulting area. Data was collected through semistructured interviews with two of the companies.

The purpose with the report is to show that it is possible to design a class-D amplifier, using a programmable FPGA mounted on a developing card from Xess and a H-bridge. The FPGA was programmed in VHDL which is the language the software from Xilinx use to implement a logical function into the FPGA The logical function corresponds to a modeling of the music signal and the modeling can be described as a comparator which compare the music signal with a triangle wave and as a out signal produce a pulse width modulated (PWM) signal. The report is also a review and evaluating of two different modulating technologies, AD- modeling and BD-modeling. A detailed part about how the H-bridge was designed and how it works. The result of this project is a working audio amplifier to a significant lower price than the products in todays market..

The purpose of the present study is to explore differences in the musical opinions and preferences and the quality of written language between pupils of two age groups (12 and 17 resp). Two classes were chosen, one from each age level. Each class/group was also divided by gender. The pupils asked to write an essay on their musical opinions and preferences. The essays were analyzed with respect to musical content and linguistic form.

Every year about 210 000 tones dry weight of sewage sludge is produced in Sweden. Most of the sludge is applied to agricultural land, plantsoil and landfill cover. Sewage sludge contains essential nutrients such as nitrogen and phosphorus. Nitrogen is limiting growth on solid ground in Sweden and can therefore be used as fertilizer to increase productivity. In order that the sludge can be spread to forest land it requires first a conversion of sludge to pellets, to make it more manageable.

As an increasingly rationalized forestry and agriculture have human interference in the form of tradition, grazing and use declined. There is a strong link between biodiversity and disturbance of the landscape. In sandy soils many insects and plants require exposed sand to survive while the disorder may contribute to seed dispersal in the woodlands. On behalf of O-Ringen Skåne 2014, a study of the interference from orienteering in sandy soil and the forest during competitions conducted. The aim is to clarify the interference of which orienteering runners contributes, through to inventory presence before and after the competitions in the bottom and field layer in three locations.

A substation must be properly protected against lightning and other external effects to the equipment in the station or staff, for that we use relay protection. They should also protect against internal errors which may occur as ground faults. There are different types of protection relays, but most common are overcurrent-, distance-, residual current- and differential protection.The purpose of this thesis was to deepen our knowledge of relay protection and to use the theoretical knowledge we got from the university studies in the work process. In the process we discovered which parameters were the most essential and calculated these for all relay protections on the substation. We also carry out a comparison between two brands of relay protection, ABB and Alstom.During our work we will test and simulate the over-current relays in a program called NEPLAN, the program will also calculate the fault currents.

The study was carried out as a time study of five wood chippers placed on trucks,so?called huggbilar. They are trucks with built?in wood chipper, chip bowl and crane pulling a chip trailer. The system is used for chipping wood fuel, transporting, and delivering the chips to heating plants.

What drove me to write this paper is the will to  examine if there is a philosophically and scientifically viable  alternative foundation for an objective morality other than what we like to refer to as "God". The  American philosopher and neuroscientist Sam Harris presents in his book The Moral Landscape a thesis for an objective morality based on science in which he states that  science can determine human values. The purpose of this paper is to perform a theoretical trial of The Moral Landscape, examining Harris' thesis and it's relations to the philosophical obstacles that stands in its way, these being mainly the famous philosophical principle "Hume's Law" and G.E. Moore's "Naturalistic Fallacy and Open Question Argument" and thus will serve as my main theoretical foundation. The results of my study was not conclusive since Harris in fact doesn't succeed in bridging the gap between facts and values on a scientific ground.

This study investigates the curriculum for English in Gymnasium class 10 in Baden-Württemberg, Germany and compares it with the Swedish curriculum for English 5. A special focus it put on the politics that decide how the curriculum is written. The German and Swedish curricula for English are quite different, although they have some main points in common. The study includes a textual analysis and observations of English classes. Furthermore, nine teachers of English in Germany are interviewed about their views of the curriculum.

This study investigates how assistive technology tools are used in the classroom by students in reading and writing disabilities in the school years immediately prior to moving to gymnasium. Through observations and interviews with two students and two teachers this study also considers if the use of these tools can lead to increased accessibility and goal fulfilment, and whether these elements are prerequisites for success. The result shows that the students use laptops in the classroom, primarily for writing longer texts, and that in order to be successful, an early start, equipment, time and positive attitudes towards the tools are important. The students use the tools in the classroom, but they have very different feelings about how included they are in the class. The participants see a clear link between the use of assistive technology tools and increased goal fulfilment. .
