Inverkan av olika joner och jonconcentrationer på porstorleksfördelningen i trämassa-fibrer
The basic ingredient of paper is the individual wood fibers. The property of the fibers depends on a variety of factors e.g., method of pulp production and processing. The final sheet quality depends in part on how the fibers interface between each other and therefore factors that affect the fiber size are of interest.The flexibility of the fibers depends in part on the pore water i.e., the fiber swelling. The sheet becomes less flexible at low water content which gives a loss in strength. Thus it becomes desirable to increase the water uptake.The experimental investigation described in this report consists of exposing the wood fibers to different ions and ionic strength and then measure the pore size by thermoporosimetry where a DSC (Differential Scanning Calorimeter) is used.
Alternativ till fortsatt elektrisk generering i Olidan
In this thesis a possible cost effective runner change of some of the units in the hydroelectric power station Olidan is investigated. The possibility to drive a unit at the same efficiency Point through a change of the turbine shaft speed and the rate of discharge is tested. Furthermore the theories behind model testing, determination of efficiency increase from model to prototype and efficiency measurements shall be discussed and analyzed with Olidan as a starting Point.A predicted curve has been built on information from model tests and field measurements on the existing runners and runner data from the test of the new model. The predicted curve shows the difference in efficiency between an existing runner and a modern one. It is the difference in efficiency that is used in the calculations that are to show whether changing to a pair of new runners will be cost effective or not.

Riskstatusbedömning : Ett djupgående analysverktyg för sevesoanläggningar
Safety and risk management currently have a starting Point based on the negative outcome of safety, thus the lack of safety. The starting Point for the thesis is to find a way to measure the positive outcome of safety through ergonomic aspects regarding chemical plants that are covered of the Seveso II Directive.Through a literature study of safety and ergonomics fourteen key aspects of safety were found. Safety Performance Indicators (SPI's) are used to assess the fourteen identified proactive indicators of safety. An analysis in three steps - called risk status assessment - is design to give an SPI its value. A pilot study of the risk status assessment was performed at the ethanol producer Lantmännen Agroetanol in Norrköping, Sweden..

Portning och utökning av processor för ASIC och FPGA
In this master thesis, the possibilities of customizing a low-cost microprocessor with the purpose of replacing an existing microprocessor solution are investigated. A brief survey of suitable processors is carried out wherein a replacement is chosen. The replacement processor is then analyzed and extended with accelerators in order to match set requirements.The result is a port of the processor Lattice Mico32 for the FPGA curcuit Xilinx Virtex-5 which replaces an earlier solution using Xilinx MicroBlaze. To reach the set requirements, accelerators for floating Point arithmetics and FIR filtering have been developed. The toolchain for the processor has been modified to support the addition of accelerated floating Point arithmetics.A final evaluation of the presented solution shows that it fulfills the set requirements and constitutes a functional replacement for the previous solution..

Skolverkets webbresurs Länkskafferiet ur genusperspektiv.
In this paper I present a website on the Internet. The EuropeanLinkTreasury ELT is a resource to Swedish children between 10 and 15 years of age. I am looking at this resource from a gender Point of view. I want to see if ELT has thought of this perspective. Are there as many websites for girls as there are for boys? I want to see if the text is separated between gender.
Scalable Services over DAB and DVB-T from a Receiver Point of View
TV and radio services have always been distributed over analogue broadcasting networks and been received on a TV -set or a radio receiver. Today this situation is changing due to digitalization and convergence between broadcasting, telecommunications and data communications. Other terminals, such as a PC, can also receive TV and radio services. Digital TV and radio can offer additional services such as e-commerce, electronic program guides and content synchronized to the TV and radio shows. If these services are to be received by several receiving terminals with different properties, the services must be adapted to the terminals.
Vad är krig? : En idéanalys av krigets aktörer, mål och medel

By whom is war fought? Machiavelli, Clausewitz, Kaplan, Kaldor, Creveld and Krulak are just a few among others who have made valiant attempts to explain war and its nature. What did they find? This essay maps out their studies in the hope of finding some kind of continuity that can give a clearer picture of what war really is.
Försämrad korrelation mellan storleken av Kebnekaises sydtoppsglaciär och andra klimatindikatorer
Intergovernmental Panel on Climate Change (IPCC) recognizes glaciers as the best land-indicator of climate change. A variety of studies have concluded, using both modeling and field studies, that above all climate parameters precipitation, particularly winter precipitation, and summer temperature controls the change in glacier mass balance. With global warming almost all glaciers on Earth are losing mass. In this study, the summit-glacier constituting Kebnekaise's south summit (called the Southern-summit henceforth), Sweden's highest Point, is studied to see how it is affected by winter precipitation and summer temperature during the period 1968?2013.
Ungas syn på integration : En kvalitativ studie om invandrarungdomars syn på integration
The aim of this essay was to acquire an enhanced knowledge about young immigrants? Point of view of integration. During a former practical training semester I became interested in what the young immigrants thought about their own integration, what their conception was about this issue. I found that it had different meaning to different persons, to some it meant assimilation, to others it meant being able to interact with the opposite gender. To examine this I used interviews and interviewed an amount of young immigrants in different stages of their studies in Swedish.
