Every day we make numerous decisions. Some are better than others. Intuitive decisions usually results in less good decisions when we do not reason about our choices. Research has been interested about the process that is behind how we make good decisions. Decisions we face every day, such as when we shop, determined using various mental shortcuts that we use unconsciously.

In this thesis a number of energy saving methods for a multiplier on algorithmic level are investigated. For the investigation a multiplier is constructed in VHDL, after which the circuit's performance is investigated. A number of techniques for reduced power consumption are introduced in the circuit and are then evaluated. The conclusions are that all investigated methods, pipelining, interleaving and voltage scaling, should be maximally made use of in order to minimize the power consumption..

AbstraktEn avgörande faktor för att kunna förebygga, avhjälpa eller lindra matematiksvårigheter är ifall pedagoger har kompetens att genomföra en kartläggning, som ger vägledning för fortsatta pedagogiska insatser (Lundberg & Sterner, 2009). Med detta som utgångspunkt var syftet med studien att undersöka yrkesverksamma specialpedagogers syn på kartläggning och yngre elevers räknesvårigheter samt hur de går till väga vid en pedagogisk kartläggning i matematik. Studien har en kvalitativ ansats med semistrukturerad intervju som metod. Deltagarna i undersökningen är två specialpedagoger med gedigen utbildning och erfarenhet inom området. Resultatet av undersökningen visar att informanterna har en formativ syn på kartläggning.

Botanist Kjell-Arne Olsson inventoried the plant fen ragwort Senecio paludosus 1983 in Scania andfound a big number of locations within Biosphere Reserve Kristianstad Vattenrike. In 2012, a reinventoryof the 1983 survey was carried out to study whether there has been any change in the fenragwort population in Kristianstad Vattenrike since the last inventory. The results show that therehas been no overall change in the number of fen ragwort in Kristianstad Vattenrike, on certainpremises they have increased in number while in others they have fallen. However, the inventoryshows that almost half of the locations with fen ragwort have disappeared during the same period.The main reason for this is that fen ragwort did not manage to competitive with other vegetation,taking in consideration this has been smaller premises with young plants. In addition to competitionother factors such as prolonged high water, grazing and caterpillars from Tyria jacobaeaecontributed to the decrease.

 Tidigare forskning inom studentliv och studenternas framgång är ett väl undersökt område. Könsskillnader, känsla av sammanhang (KASAM) och socialt stöd är några av de faktorer som har visats påverka studenternas akademiska self-efficacy. Studiens syfte var att undersöka relationen mellan kön, KASAM, socialt stöd och studenternas akademiska self-efficacy. 124 högskolestudenter i Mellansverige deltog genom att svara på en enkät bestående av College Academic Self-efficacy Scale, Social Support Questionnaire 6 (SSQ6) samt Sense of Coherence scale (SOC-13). Materialet analyserades med Pearsonkorrelation, regressionsanalys och t-test.

During 2006 an estimated number of 150 persons are supposed to have been killed in road accidents caused by speed limit violations. Through Automatic traffic security control (ATK) the Swedish road administration (Vägverket) is working towards lowering the number of speed related accidents. By placing the speed cameras on roads they've managed to lower the average speed at those places. The enlargement of the number of speed cameras is based upon knowledge about for example how high the risk is for speed related accidents on the roads. The speed cameras always measure the speed in which every vehicle passes, but aren't constantly activated to register speed violations.

This Master Thesis is a product development project that has been carried out in cooperation with Scania CV AB. The purpose has been to find the relationship between geometric parameters and the swirl number for an XPI- cylinder head in order to improve the design specification.The increased focus on environmental issues from society leads to tighter emission legislations for the truck manufactures. In order to drive the development forward considerable resources are spent on research and development on diesel engines and its combustion process. The inlet air has a significant impact on the formation of emissions and the flow that is desired is called swirl. Swirl is achieved by making the air rotate around the vertical axis of the cylinder.Earlier cylinder heads that has been developed at Scania CV AB have shown clear relationships between geometric parameters of the cylinder head and the swirl number.

The purpose of this study is to investigate the unaccompanied children's experiences of the support offered at group homes intended for this group. The purpose is also to find out if they feel like the stay at the group home has prepared them for an independent life. The study has a qualitative approach and results collection occurred through semi-structured interviews. Seven young men aged 18-20 years were interviewed, all of them have lived for at least one year in a group home and are now living in their own apartment. The results have shown that the adolescents had both positive and negative experiences from their stay at the group home and that they have different views about whether they have received the support they need to cope independently.

Today older people?s health and life quality are current topics of conversation in society. The number of old people is increasing and their health is deteriorating, that is why there is a need of new ways of meeting their necessities. In this study we have tried to illustrate heads of districts reasoning concerning pets? significance for old people in special housing.

The purpose of this study has been to describe and analyze how former foster children experienced foster care which have been filled with maltreatment and neglect and how this has influenced their adult life when it comes to health, education and relationships. We also wanted to study how the former foster children coped with their placement. Furthermore we wanted to study whether there has been any turningpoints during their growth. Finally we wanted to describe how the former foster children experienced the authorities control. To make the purpose of this study complete we chose to use qualitative interviews with six former foster children as our research method.

The purpose of this study was to find out if motion movements, e.g. number of lying bouts and lying time with a registered activity monitoring sensor can detect an impending calving and thereby be used as a measure and an indicator for an upcoming calving. For this, automatically step sensors were used and were attached to one of the cows? hind leg. The sensor registered the individual step and movement activity of the cow.

Several studies have investigated the relationship between different measures of innovative activity, such as patent statistics and R&D expenditures and some have looked deeper into the differences between large and small firms regarding number of patents issued per employee or per R&D dollar. In this paper, the objective is to find out if there are any indications of a barrier to entry (due to economical factors, lack of knowledge etc) for small firms to get into the field of patent handling. The approach is to first set up a hypothesis based on some simple assumptions about how firms would make decisions about whether to apply for a patent or not and thereafter use econometric methods in an empirical investigation. The data used for this study are figures on number of employees, number of patents granted and R&D expenditures for the Swedish firms in the pulp and paper industry. The main conclusion is that, based on the analysis of the data from this rather limited group of firms, no such barrier can be seen..

Parents play a major role in the care of their children during hospitalization.Purpose:The purpose of this study was to investigate parents´ experiences of having a child diagnosed with scoliosis before the age of five undergoing repeated surgeries in the back.Method:The study had a qualitative descriptive design. Five parents with children aged 5-15 years, who have undergone several operations were interviewed about there experiences of the child?s illness and treatment. Phenomenological-hermeneutical analyze where used.Results:The parents felt a sense of shock when they were told about their child?s diagnose and treatment.

In 1993 Sweden introduced a new Forest policy, with a larger freedom of action for the forest owners, but in the same time the forest owners are expected to take greater consideration of the forests and the environment, that is required by the law. This is necessary to be able to obtain the goals of the new policy. Therefore the demand for competence and guidance is larger than before. At the same period of time organisations where slimmed and trimmed during a economic recession and the question is how this has affected the number of employees on different levels in the organisations, the competence of the employees and their internal education and if these changes affects the possibility of implementing the forest policy. This study contains three points in time where measures were made, 1990, 1995 and 2000.

The number of residential fires has not declined sufficiently since the smoke alarm entranced the Swedish homes, fires lead to devastating consequences in which possessions, homes and worst of all human lives are at stake. Every year, about 80 people get killed and more than 500 get´s injured in residential fires, often due to lack of safety equipment. The number of fires caused by electrical appliances has risen and taken over a period of ten years the fire caused by a forgotten stove has increased by 70 percent. Preventing the risk that a fire would start on the stove would saves money, worry and most importantly, lives..
