The Squares Family is a game developed as a learning aid in mathematics. With its graphical representation of the decimal system, the four basic arithmetic operations and positive and negative numbers together with a learning agent as pedagogical approach, the game?s primary purpose is to motivate students in their learning of mathematics. Although the game is strictly based on mathematical rules it attempts to encourage students to play and work with math without experiencing it as mathematics as this is initially not obvious. The game being internationally tested on normal performing students, this project introduced the game to six Swedish students who experience low motivation for and/or difficulties in mathematics.

In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.

In today?s technological society, there are increasingly less physical demands on the locomotor system. However, despite that notion strength and function in the hand?s complex biomechanical system are in fact both needed to cope with daily life. The grip function is a main function in the hand and is used in many examples of scientific research, for instance when assessing physical health and predicting the probabilities of premature mortality.

År 2005 implementerades IFRS 3 och IAS 36 i Sverige. I och med detta genomför företag nedskrivningsprövningar av goodwill. Dessa kan inbegripa nuvärdesberäkningar av framtida kassaflöden. Forskarna Carlin och Finch utförde år 2009 en studie på australiensiska börsnoterade företag för att undersöka om diskonteringsräntor, vilka används vid en nedskrivningsprövning, sätts opportunistiskt. Studien genomfördes genom att de visade på förekomsten av avvikelser mellan diskonteringsräntan som företagen redovisat och en av forskarna estimerad teoretisk diskonteringsränta beräknad genom the Capital Asset Pricing Model [CAPM].

For most pupils homework is a natural part of school and their education and there are several providers of homework assistance: the pupil's parents, sibblings, friends, Internet forums, hired private tutoring, non-profit organisations and at times even the pupil's school. This study has investigated the use of the school-based homework assistance programme at the Upper Secondary School of Psychology in Stockholm and why the programme is not more frequently used by its pupils. The school offers homework assistance two hours each Thursday afternoon, with at least two teachers being present to tender for the school's 127 pupils. The cost of the programme has been estimated to approximately 12 500 Swedish kronor per week. Through the main use of a questionnaire given to both the school's students and teachers, as well as an interview with the school's headmaster, this study will show that despite receiving the opportunity few pupils take part of the programme on a regular basis.

Today 70 percent of the people residing in nursing homes are undernourished. One way to avoid that an individual is affected by malnutrition it is a necessity that the meals is customized after special needs current among other things as energy and protein. Food record is a method that can be used to examine and evaluate if an individual is getting sufficient nutrition and energy to cover the daily needs. For those suffering from malnutrition it is recommended to eat energy and protein enriched diet.AimsThe aim is to compare the intake of energy and macronutrients in a group of elderly people living in a nursing home in southern Sweden before and after the introduction of an energy and protein enriched diet based on newly developed recipes.MethodsFood record was made during four days. Food record means that everything that is consumed by an individual is noted precisely.

The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

Internet is used today as a traditional medium for information exchange and social interaction. One of these is virtual meeting places where people meet and exchange information, socialize and exchange knowledge with each other. The group has chosen to examine the factors affecting the use of web forums, one of the virtual meeting places that exist on the Internet today. And look at how people use the web forum today in the current situation and how to design a web forum.A survey was conducted to find out how people look at web forums today, 80 people participated, and they got to talk about what they think about different web forums regarding how and why the use these them. Guidelines on how a web forum should be designed were also developed.

Hägglunds Drives in Mellansel, Sweden, manufacture radial piston hydraulic motors foremostwithin applications in the industry. These motors have several sliding contacts, one of these, isthe contact between piston ring and cylinder bore. The radial piston hydraulic motors advantageis to produce high torque in very low rotation velocity, this result in that the maximum slidingvelocity between piston ring and cylinder bore, during the whole stroke, is very low. Theconsequence of this low sliding velocity is that the contact between piston ring and cylinderbore, during the whole stroke, is bound to the boundary lubrication regime. This result in, thatthe piston ring is exposed to wear, thus affect the service life of the complete hydraulic motor.To minimize wear of piston ring, it is essential to determine the oil film thickness between thepiston ring and cylinder bore.

AimThe main aim of the study was to investigate the difference in bilateral deficit between rowers and sprinters during maximal eccentric/concentric muscle actions.? Are there any significant differences in bilateral deficit between rowers and sprinters?? Do the amount of years in practice effect the bilateral deficit?MethodFourteen male subject participants divided in 2 equal sized groups (7 individuals in each group; rowers and sprinters) performed maximal unilateral/bilateral eccentric and concentric muscle actions in a leg press machine at a velocity of 0.2m/s. The range of motion in the knee joint was 70° ? 140°. Dependent t-tests have been performed within each group pre and post test.

This report was written as a result of a Bachelor Degree Project at the School of Technology and Society at University of Skövde spring 2007, together with Jede AB in Mariestad. The report covers the development of a door to a coffee vending machine that is under construction, and will in a chronological order describe the project from ideas to final product.The project started with a rather extensive feasibility study that thru market research and user tests sorted out the opinions of potential customers, concerning today?s available assortment. Technical areas concerning materials and manufacturing methods were also scrutinized for the consideration of the possibilities of a future production.The next step was to constructively generate ideas and thoughts that later on could grow to be potential solutions. After several weeks of hard work and pieces of good advice and recommendations from the assigner, four comprehensive concepts were built up.
