Since their invention in 1999, CubeSats have become a widespread standard for small picosatellite missions. CubeSats allow for quick development of satellite payloads and launch in space without the high costs of a normal satellite. Emphasis during the CubeSat design process is placed on use of commercialoff- the-shelf (COTS) components and reuse of previously-designed units.This report describes the interfacing of a scientific magnetometer, the Small Magnetometer in Low-Mass Experiment (SMILE) to such a CubeSat mission, the Space Weather using Ion spectrometers and Magnetometers (SWIM). Design of a complete platform for use in multiple such missions is presented here.Modularity is one of the key aspects followed in the course of the work. A new board containing the analog pick-up and compensation circuitry for SMILE has been designed to fit inside a CubeSat frame.

Fuel pellets are in Sweden mainly produced from sawdust and cutter shavings. Before the pelletising process the raw material is dried to attain consistent moisture content and ground up in a hammer mill. In the densification process (pelletising) the ground material is forced through holes in a rotating die. This heats up the wood particles which cause them to soften and self bond. After the process the pellets are cooled, sieved and bagged. The milling process creates a wide range of particle sizes.

An ongoing concern within the Intellectual Technological world is the issue of security. There are severe consequences if someone without permission searches a computer for secret information that was left unlocked. In order to prevent this situation from occurring, rules about password lengths or employees bringing personal flash drives into the company should be created and followed.As Internet become a worldwide phenomenon, the use of information technology is growing more than ever. With more use and accessibility to Internet, new threats against companies have also emerged. This report brings up the main issues that a company needs to regulate today.The standard for regulations and proposals for IT-security comes in a document called ISO 17799 and very complicated for those who are not experts in the field.

When the Swedish Forestry Act was changed in 1994, brushing of young stands became non mandatory. Since then the annual need for brushing in the country has increased by about 100 000 hectares per year. In later years the price for biomass energy has increased to the same level as pulp wood. The high price on biomass energy and the large areas of stands in the need of brushing has created a new market with its own technical, economical and environmental conditions. There is a development of various techniques to manage the forestry stands with late brushing.

Cellulose nanocrystals (CNC) are great candidates for composite materials. The reasons why CNCs are such attractive materials for them are due to their great mechanical properties, high aspect ratio and low density. On the other hand, hydroxyapatite (HAp) is a kind of calcium phosphate and a main component of bones and teeth. The purpose of the present study is to make oriented nano-sized composites with CNC and HAp. Although some researchers carried out to make CNC composites with HAp for biomedical materials, nano-sized and oriented ones haven?t been achieved yet.

Vid TCF-blekning av pappersmassa är väteperoxid en av huvudkemikalierna. I dagsläget är det svårt att styra blekstegen. Operatörerna måste ta hänsyn till produktionstakt, blekbarheten på massan varierar och fördröjning i trender. PO-bleksteget på Södra Cell Värö har en ungefärlig uppehållstid på 4 timmar och det är först efter så lång tid som man kan se hur en förändring verkligen slår igenom. Överblekning kostar väldigt mycket i kemikalieåtgång och det är därför efterfrågat ett sätt att kunna styra och optimera peroxidblekningssteget.

Fallstudien delades in i två steg där första steget i studien var att kartlägga energi?ödena in och ut från bruket.Andra delen av studien innefattade att kartlägga de interna processerna och deras energi?öden.

Deposits can be formed in the paper machine due to sticky materials from wood and recycled paper. These deposits get stuck on process equipment and cause the product quality to deteriorate and the efficiency of the paper machine is reduced. The purpose of this thesis is to increase the understanding about deposits among machine operators, and to suggest methods that can be used to reduce the amount of deposits formed in Bravikens paper machines.To fulfill the purpose of the thesis a pre-study, a literature review and interviews with machine operators and production staff, were carried out. These methods led to the planning and creation of an education about deposits for machine operators.The education about deposits for machine operators consisted of an interactive lecture to introduce the subject of deposits and a subsequent discussion. This approach was chosen to give the machine operators the opportunity to discuss their work situation on the paper machines related to their new knowledge about deposits.

To investigate the possibilities for effective soil tillage, that could imply lower costs, lower negative environmental impact and in addition a meaningful occupation for foraging pigs, a field experiment was carried out in Gränna, Småland, during growing season 2006. The experiment contained two treatments that were repeated three times and were carried out on a couch grass-infected fallow on a light soil close to Sweden?s second largest lake, Vättern. Ploughing was one treatment and pig rooting followed by ploughing, was the other. The experiment was conducted according to the guidelines of organic growing and seedbed preparation was done the same way in the two treatments. The pigs, three groups of five half-year old Linderödssvin (an old Swedish breed), was encouraged to perform an even tillage by strip-grazing, i.e.

Summary:The Clinical Training Center at the Swedish University of Agricultural Sciences in Uppsala uses new methods for educating and training veterinary students. Among these methods are computer programs. The aim of this study was to create an interactive application based on data from horses CT-scanned at the Center for Medical Image and Visualization at Linköping University Hospital. The purpose of this application is for veterinary students to be able to use multidimensional visualization to study equine anatomy. The resulting application named "EQUINE VIRTUAL ANATOMY - Flash in the Tunnel" consists of data from six heads, one left foreleg and a wooden dalahorse.

In the production of pulp, paper and cardboard, a large amount of water is used daily. The water has to be purified in the internal purifying plant before it reaches the receiving body of water. In the biological purifying stage at the Stora Enso Skoghall mill, an aerated basin is used where the microorganisms, using oxygen, oxidize the organic material to carbon dioxide. The air is pumped from the bottom of the basin and the oxygen can then be transported from the air bubbles to the water through diffusion. The problem with aeration of waste water from the forest industry is that wood residues, such as fatty acids, are making the transport of oxygen in water more difficult.

As demand for renewable energy is increasing rapidly, the market for biomass pellets is expected to continue to grow in the near future. Most of the new raw materials that are discussed for pellet production have one thing in common; the production costs will increase compared to using traditional raw materials such as sawdust and planer shavings. The aim of this thesis is to investigate to what degree increased use of new raw materials for pellet production will affect the general pellet prices in Sweden and to survey what plans Swedish pellet producers have concerning new raw materials. To investigate the raw material situation of the Swedish pellet producers an industry survey was performed. Literature studies were also made on previous research in the subject field. Calculations of the production costs for pellets were done for the raw materials sawdust, wet sawmill chips and energy wood respectively. New raw materials are already used by the large-scale pellet producers in Sweden.

Vi valde som kandidatarbete att göra en webbapplikation för att hantera webb-tv-lösningar för att vi ville samla kompetenserna inom programmet medieteknik där videoproduktion, flashproduktion, grafik, webbutveckling samt serverhantering skulle ingå. Vår webbapplikation skulle skilja sig från redan befintliga lösningar genom att den enkelt skulle kunna anpassas för olika kunder snabbt och effektivt. Detta skulle vi uppnå genom att bygga webbapplikationen kring moduler som alla hade olika funktioner på plattformen, och kunde bytas ut med en knapptryckning. I projektet jobbade vi kring konceptet "från produktion till distribution" med vilket vi menar att både kan producera den bästa webb-tv:n samt ha den smidigaste lösningen för distribution som de flesta kunderna skulle ha råd med. På dagens marknad så är antingen lösningarna för enkla och avskalade eller för anpassade och dyra för att passa den normala kunden, med en normal kund så avser vi ett företag med cirka 10-100 anställda.

Forest enterprises have always searched for ways to improve efficiency. For the past few years there has been an emphasis on stock-keeping levels. Increased demand for fresh round timber and the need to decrease the amount of tied-up capital has made the forest industry reduce its inventory levels. This has brought on a higher demand on the timber supply from the forest management districts concerning both delivery in time and assortment output. As a result, the flow of timber has fluctuated a lot with serious consequence for the timber supply during 1994.
