RUT-avdraget - jämställdheten i att betala för att slippa obetalt arbete i strävan efter lika villkor på arbetsmarknaden
Denna studie berör olika developer zones som idag drivs av företag i Sverige, och om hur dessa är uppbyggda. Den tar upp de problem som dessa företag har stött på, samt vad man ska tänka på vid uppstart och användning av en developer zone.Att låta sin developer zone vara helt öppen eller helt stängd är inte det mest optimala sättet eftersom man i den helt öppna versionen låter sin information vara tillgänglig för allt och alla. Den helt stängda versionen stänger ute kunskap från developer zonen. Genom att sätta upp en developer zone med båda delarna, dvs. en öppen del för utvecklare som intresserade att utveckla innovativa tjänster/produkter och en stängd del för företag som tillsammans med ägaren av developer zonen har ett ekonomiskt intresse, så uppnår man en mer kontrollerad form.
MCNP-modell för beräkning av neutrondos och DPA på reaktortanken vid Ringhals 2
In this report an MCNP (Monte Carlo N-Particle) model is described for the reactor vessel at Ringhals 2. The model is validated against the specific activity in neutron dosimeters, extracted in 1977, 1984 and 1994. The validation showed that the calculations of the model are within the requirements of a maximum of 20 percent uncertainty for every neutron dosimeter except one, extracted after the first cycle. The uncertainty of this cycle was mostly due to the operation data rather than to the MCNP model.The model has been used to investigate various questions concerning radiation damage. The reliability of the traditional measure of radiation damage, fast neutron flux (En > 1MeV) has been evaluated. This has been done by taking the ratio for this and another measure of radiation damage, DPA (Displacement Per Atom), for various positions and layers.
Optimering av ett småskaligtvattenkraftsystem
This master thesis covers the seasonal planning of a small scale hydropower system. The system in this study is owned and operated by Mälarenergi Vattenkraft AB. The total system consists of 4 different main rivers with 24 hydropower stations and several dams. The total installed power in the system is 43.75 MW. Most of the hydropower stations are regarded as small scale hydropower stations and thus entitled to green certificates.In this report the issue of planning is formulated as an optimization problem.
Avlastningsarmstöd till Grip-it : Optimal positionering av övre extremitet vid gripstyrkemätningar
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.
Volymmätare för tall- och grankott
This thesis describes the planning and development of a volume meter of pine and spruce cones. The product was designed and developed for Stigsjö Skog och Frö AB in Härnösand. It was developed taking into account a number of requirements set by the supervisor David Zetterlund. The main requirements were that the volume measurement would be fast and give accurate results. These are two requirements that are missing in today's volume measuring method which is very problematic for the company.The plant was visited several times in Härnösand, mainly to discuss the generated concepts with the supervisor and perform tests on the prototype.
Effektivare energianvändning på Totebo AB
The main goal with this thesis report was to come up with ideas of how to make the use of energy more effective and thus save money for the company.First a survey was made to find out where and how the energy consumers were divided within the company. The results were then used in calculations to find out how much money that could be saved and how long it would take to get back the investments.There is a big potential in saving money by recovering heat from the UV-lamps with a heat exchanger. It would also even out the pressure in the factory which is a source to heat loss and a cause for discomfort amongst the employees. It?s possible to save 105 000 kr in a year and the money needed for the investments is 600 000 kr.By using the recovery air more effectively the company could save up to 250 000 kr a year in lowered heat purchases, but this would require the use of automatic dampers.If you reschedule the running times for the wood chipper and invest in some kind of load management, for example Sydkraft?s ?Energidirigent? you can save at least 42 000 kr.
Effektivisering av byggproduktion med VDC och förstärkt verklighet : Streamlining construction work with VDC and augmented reality
Virtual Design and Construction (VDC) is currently used more and more within construction design and planning as well as construction as a streamlining tool aiming to improve communication and decrease the number of construction defects. VDC is constantly developing, but what comes next? The augmented reality (AR) technology is currently not used within construction in Sweden but should be considered as the next step in line regarding the integration of reality and digital information. Using this technology design can become reality even before it?s actually built.The purpose of this study has been to carry out an inventory of the existing AR technology and its shortcomings, and also to identify possible applications within the construction phase.
Översättning och validering av pVHI : för barn 6 till 10 år
Studies indicate that between 6-9% of all children has some type of voice problems. Voice problems in children may have different etiology and can affect all ages. In Sweden, there is a lack of a standardized questionnaire addressed to children with voice problems and their legal guardians. The purpose of this study was to translate and validate the Pediatric Voice Handicap Index (pVHI) in Swedish children aged 6 to 10 years. The study was carried out through an internet-based assessment form for children referred to speech and language pathologist/ phoniatrican due to voice disorders in Sweden and a matched control group of children without voice problems.
Är reducerad jordbearbetning ett alternativ? :
Today cultivation of cereal in Sweden has high costs for establishment in relation to the rest of the world, and if this cultivation will be able to continue, the farmers have to control their costs. It is important to see all costs, not the maximum harvest achieved, but the net result. All farmers have different conditions with respect to soil, direction of the farm and were the farm is located geographically. With the right knowledge and ambitions, we think most farmers could change to reduced tillage.
In this paper we have tried to find out if reduced tillage is an alternative for farmers.
Freshwater pearl mussel as indicators of Swedish streams - a comparison between freshwater pearl mussel and biological quality elements
The freshwater pearl mussel (Margaritifera margaritifera) is a large freshwater mussel. Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity. Moreover, due to the species complex life cycle, including a larval stage on the gills of salmon and trout, and sensitivity of early life stages, regeneration is often used as an indicator. The freshwater pearl mussel is also used in the expert judgement of status classification of benthic invertebrates according to the European Water Framework Directive.
The purpose of this study was to gain a deeper understanding of the freshwater pearl mussel as an indicator for Swedish streams. It was made with two types of
association analyses.

Tillfälligt sammanstatt och samtidigt interoperabelt och robust : Ledningssystemets dilemma
Ledningssystemområdet genomgår stora förändringar med anledning av Försvarsmaktens strategiska inriktning att skapa flexibla, tillgängliga och stående krigsförband. Inriktningen innebär en utmaning inom ledningssystemområdet då den medför ett tydligare krav än tidigare på att ledningsmateriel, teknik och personal är ständigt uppfyllda i samtliga krigsförband.Modulära enheter och förband som på ett flexibelt sätt skall kunna sättas samman till stridsgrupper skapar vid varje tillfälle ett behov av att designa operationen med dess ledningssystem. Ett ledningsstödsystem vars övergripande syfte är att stödja chefers utövande av ledning, det vill säga att tillgodose ledningsbehoven. Denna studie analyserar hur Försvarsmaktens strategiska inriktning påverkar ledningssystem- och ledningsstödsystemområdet, vid en insats med tillfälligt sammansatta förband på operativ och högre taktisk nivå.Syftet med studien är att analysera vilka faktorer som är centrala för effektiv ledning vid en gemensam operation.Studien menar att de centrala faktorerna vid ledning av en gemensam operation härrör sig till analys av: aktuell verksamhet och dess specifika behov, operationskonst och taktik, vald organisations behov och sammansättning. Analysen resulterar i specifika ledningsbehov och metodanpassningar.
Skatteverkets ställningstagande om kortare avbrott : Rättskällevärdet i förhållande till legalitetspricipen och förutsebarhetens påverkan
Individuals considered as tax residents in Sweden may if they are working abroad for six months alternatively one year be granted a tax exemption concerning the income originating from the work abroad. Short intermissions (kortare avbrott) are permitted without impact on the tax exemption, however this requires that the intermission is not placed in the beginning or in the end and that the stay in Sweden does not exceed 72 days a year. A time limit regarding intermissions in a third country is however not regulated. There-fore the Swedish tax agency (Skatteverket) has published a non binding standpoint which regulates the entire intermission allowed to a maximum of 96 days a year whereof 72 days may be spent in Sweden. The definition is more extensive than earlier and uncer-tainty occurs as to whether the extension contradicts the principle of legality.The purpose of the thesis is to investigate the value of the Swedish tax agency?s stand-point concerning short intermissions.
Privilegierad mobilitet? : Flygplatser, resande och säkerhet
Never before have so many moved so frequently as now. Mobility lies at the centre for the concern ofstates, business and technological development. Some even claim that we are witnessing a mobility turn inthe social sciences. However, as the capacity to move has increased so too has the control and surveillanceof mobility become more extensive. Since September 11, 2001 security has been the defining paradigm fora variety for actors.
PPM - Passivt Placerande för Många : En analytisk studie av premiepensionsspararnas avsaknad av strategier för fondval
Introduction: In 1998, the pension system was changed and the so called PPM system was introduced. The PPM system is partly fund-based, partly distribution-based. There are approximately 700 different investment funds to choose between, at a maximum five for each individual. For persons who are not familiar with the financial market, the choice might be difficult. The lions? part of the investors do not seem to have an active strategy.
