The aim of the work was to investigate the possibility to combine information from PPG and bio-acoustic technology to extract information that is related to the blood pressure. The measurements have been carried out with several different configurations. First the relation between arterial sounds and the PPG-signal was studied. After those measurements with both PPG and the bio- acoustic technique was concluded on people in different positions and after riding a bike. The goal was to vary the blood pressure.

The company Somas, Säffle, has assigned Fredrik Kjellin the project of finding out how ?KVTF DN250?, one of their own valves, reacts on cutting forces under production. They wish to know if and then how much it?s possible to minimize the wall thickness of the valve with neither plastic nor to big elastic deformations caused by processing.The most critical processes have been identified as rough lathing. The study has shown that the marginal for a wall thickness of two millimeters, to fall short of the yield stress in the most critical process, is good.

This report treats two assignments that concerns the biofuel furnace at Billerud Skärblacka AB and how these assignments were solved. The assignments were: reducing the number of CO-spikes and tuning the overfire air control loop. To reduce the number of CO-spikes the possibility that skewness in mass distribution affects the number of CO-spikes were study. The skewnwss of mass distribution was controled and adjusted with two experiments. The conclusion that was made is that the skewness of mass distribution were not sufficient enough to affect the number of CO-spikes.

Since prehistoric time man has used wood to build their environment. The material?s availabilitycombined with its good mechanical properties has often made it the material of choice. Like allmaterials exposed to natures degradative processes the properties of wood decreases over time.Rot, UV radiation and attacks by insects and pests damage wood if not protected. Since we wantwhat we build to consist, optimizing our building materials durability is of great interest.Techniques and methods for increasing the endurance of wood have been developed in severaldifferent places and for a long time.

I detta arbete undersöks hur bestraffningsmetoder för att bestraffa storleken på GP-program påverkar generaliseringsförmågan. Arbetet grundar sig på ett arbete som Cavaretta och Chellapilla gjort, där de undersöker skillnaden i generaliseringsförmåga mellan bestraffningsmetoden ?Complexity Penalty functions? och ingen bestraffningsmetod.I detta arbete har nya experiment gjorts med ?Complexity Penalty functions? och ?Adaptive parsimony pressure?, som är en annan bestraffningsmetod. Dessa bestraffningsmetoder har undersökts i samma domän som Cavaretta och Chellapilla och ytterligare i en domän för att ge en bättre bild av hur de generaliserar.I arbetet visar det sig att användningen av någon av bestraffningsmetoderna ?Complexity Penalty functions? och ?Adaptive parsimony pressure? oftast ger bättre generaliseringsförmåga hos GP-program.

ABSTRACTPressure ulcers are a serious health damage that causes great suffering, prolonged hospital stays and increased health care costs. Patients undergoing surgery are at high risk of developing pressure ulcers and it is the operating theatre nurse responsibility to protect against health damage through nursing. There are little research made in the area of perioperative pressure ulcer prevention. In order to investigate perioperative pressure ulcer preventive care measures that are described in the litterature and to answer the question how the operating theater nurse can protect the patient, a pilot study of a systematic literature review was carried out. Data base searches were conducted in PubMed and Cinahl from where ten articles were selected and examined for their quality and content.

Aortic insufficiency is a very common valve problem in horses and most often affects older individuals, but nevertheless existent within younger ones. The root cause for aortic insufficiency can be varied, for example; endocarditis, ventricular septum defect or congenital valve disease but the most common are progressive valve degeneration or elite competition. Depending on the root cause, different changes can be observed on the aorta valves, but they do all have the same effect, the valves do not seal properly and blood leaks backwards. Many horses can, even with this deficiency, perform highly without any visible impacts and there is therefore no need to treat those subjects. Most often the symptoms arise at a later stage in life and they are, more often than none, put down for other reasons. In the occurrence of the clinical symptoms showing, treatment guideline is to inhibit these symptoms since the valve degeneration is presently irreversible.

Background: A health damage that has been specifically related to nursing is pressure ulcers. Pressure ulcers are a complication caused by disease, care and treatment and can result in great suffering for the patient. Pressure ulcers can affect people both physically and psychosocially and is experienced, by most patients, as a serious and unnecessary complication of care. Today there are hundreds of identified risk factors for pressure ulcers described that can be divided into patient and care-related risk factors. A successful pressure ulcer prevention and treatment is to reduce or eliminate the underlying causes for the development of pressure ulcers, prevent deterioration and to treat existing ulcers.

This master thesis project at KTH is performed in the Mechanical and Aerospace Engineeringdepartment at University of Florida (UF). The thesis is a small part of a gas turbine researchproject where a vapour absorption refrigeration system (VARS) and a high pressure regenerativeturbine engine (HPRTE) are integrated together. The main objective is to build a computermodel of the VARS. The computer model is supposed to be used to analyse the off-designperformance of the VARS and should also be easy to integrate as a subroutine in a more complexsystem model. To model the VARS some knowledge of the absorbent/refrigerant mixture had tobe well known, in this case a mixture of ammonia and water.

SUMMARYThe first and most basic skill a rider needs to learn is how to sit correctly in the saddle. This decides whether or not the rider will be able to follow the horse?s movements and use her riding aids in an efficient way. This correct seat is based on a straight line between the axis of the hip and heel. The seat must rest against the saddle with equal weight on both buttocks and the inside of the thighs.

Pressure ulcers cause a lot of patients unnecessary suffering. This suffering could be decreased through improved knowledge about prevention, so that pressure ulcer will not appear. The purpose with this review was to study how nurses assess risk and prevent pressure ulcer, and to study how nurses use available knowledge. The method consisted of searches in databases and searching trough references. Our result is based on ten articles, qualitative, quantitative and reviews.

AbstractIntroductionWedged shoe insoles are used as a treatment for different problems in order to change the ground reaction force. They can secondary cause different loading patterns under the foot compared to normal. No previous study has, to the author?s knowledge, clinically evaluated the plantar foot pressure with different full-length wedges in normal persons.PurposeThe purpose was to evaluate the plantar pressure with different degrees of full-length wedges in normal persons.MethodTwenty persons with normal feet have participated in this single blind study. Wedges were produced clinically in four different shapes, 3° valgus, 0° flat, 3° varus och 6° varus.

By our employer Camatec Industriteknik AB have we been given the assignment to continue with the previous work ?Design of strip feeder?. Our goal with this work is to come up with a design basis for a strip feeder.Functionally a strip feeder consists of two rollers which with the aid of the friction between the strip and the coating on the roller create a strip force that pulls the strip through the working progress.Demands on this project:? 10 ? 600 mm in strip width and 0,1-1 mm in strip thickness.? Minimum 30m/min in production speed.? A maximum strip force on 30-40 kN.? The cost of the strip feeder?s components is to be considered of economy and quality.The need of a strip feeder occurs when the coil doesn?t manage to feed or pull the strip before or after a working process. The strip can otherwise be exposed by a permanent yield deformation or a change in the strip material if it?s pulled trough the working process only by the on ? and of-coils.

The global climate-change means increasing mean-temperature and higher precipitation in Sweden, which leads to shorter periods of frozen ground in the forest. At the same time the harvesting machines are getting bigger and more powerful. The forest industry aim at an even wood flow, and the ground damage has to be as low as possible. The two biggest causes for ground-damage is the bearing capacity of the forest ground and the ground-pressure of the harvesting machines. The aim of this study was to find out some rules for the machine choice considering ground pressure, when harvesting on ground with low bearing capacity.A field study, using a Valmet 890.3 forwarder, was carried out where different ground pressures and their effect on the ground were tested on two different types of ground.Additionally, an inventory of damaged harvesting grounds was made.
