Utvärdering av magnetiska alternativ till optisk scanning

This thesis includes an energy survey of the Herrgården pre-school, which has a modern heating- and ventilation system, and a comparison with Östers pre-school which has an older system. An energy survey of Östers pre-school has already been done by a group of three students and all the calculations and values have been collected from that survey. As of today, both pre-schools are heated thru district heating. It will be much easier to make smart and feasible energy-saving-measures by first conducting the energy survey.Herrgården pre-school in Gävle houses 81 children, therteen teachers, one cleaner and one cook. It was finished in the middle of 2009 and the staff has been very pleased with the in-door climate.

Integrerat Performance Management System -En studie om ett ledningssystems påverkan inom Volvo

The research within the management control systems-field and more specifically performance management has been rather shallow and not much has happened the last decades besides the balanced scorecard. The researchers see a lack of studies focusing on the effects of an integrated performance management system and also how it affects the different hierarchical levels and the tasks to perform.We decided to perform an essay with case study-characteristics by looking at both the strategic and tactical level at Volvo Group, or more specifically Group Trucks. We performed three different interviews, one at the group level and two at the division level. The aim was to see what effect an integrated performance management system had on the tactical level (i.e. the divisions).Our findings and corresponding analysis suggested that Volvo was a rather centralized company in order to get the performance management system to work by enabling a ?weekly control?.

Vibrationsdämpning av värmepump

Thermia Värme AB is one of the market leading manufactures of heat pumps. In order tomaintain this position, the company wants to improve the vibration characteristics of theirproducts. The aim of this thesis is to develop product design changes that lead to a reductionof vibrations in the heat pump Thermia Diplomat 8.The main cause for vibrations in the system is flow pulsation and mechanical forces inducedby the scroll compressor. Vibration is transmitted through the compressor piping and receivedby the heat exchangers, from where it is further transmitted to the connection points for theradiator and heat source circuits.A number of design changes in order to improve the vibration characteristics have beenevaluated through calculations and practical experiments. The changes have included thecompressor and heat exchanger mountings, the compressor suction and discharge line pipingand also pulsation dampening.The results of the experiments show that the vibration levels in the connections for the heatingand brine circuits can be decreased strikingly through changes in suction and discharge linepiping.

Mona-Lisas leende : Upplevelsen av ma?ns och kvinnors glada och arga ansiktsuttryck

Att kunna ge uttryck fo?r emotioner och fo?rsta? andra individers emotionella signaler kan vara skillnaden mellan liv och do?d eller mellan social gemenskap och utanfo?rskap. Det finns inom forskningen spridda resultat om hur emotioner upplevs i ma?n och kvinnors ansikten samt motstridigheter i forskningen om vilka emotioner som har fo?retra?desra?tt, a?ven kallad superiority effect. Viss forskning visar att arga ansikten har en dominerande fo?retra?desra?tt na?got som kan kopplas till o?verlevnadsmekanismen.

Att förhålla sig till den nära historien - och planera för den avlägsna framtiden :

This thesis concerns the term contemporary history and its role in landscape architecture. Today?s contemporary history is defined as the planning and architecture connected to the 60s and 70s, in Sweden carried out as a large scale planning project called ?Miljonprogrammet?, which set out to build one million new residences in ten years. Initially, the term contemporary history and its complex of problem are examined. To deepen the picture of today?s situation, a historical review has been made, starting in early 1900s ending in 2000s concerning how different planning and architectural influences has varied through the years.

Tidig elit? : En kvantitativ studie om eleverna på Sveriges elitinnebandygymnasier

Syfte och frågeställningar:Studiens huvudsakliga syfte var att undersöka vilka elever som går på Sveriges elitinnebandygymnasier efter reformen av den gymnasiala idrottsutbildningen.Ytterligare ett syfte var att urskilja påverkansfaktorer i utvecklingsprocessen som innebandyspelare.- Hur ser förekomsten av relative age effect ut på elevpopulationen?- Hur upplever eleverna sina förväntningar och egna förmåga i sitt innebandyutövande?- Hur ser elevernas idrottsbakgrund ut?Metod: Enkätundersökning har använts som metod i denna studie. Totalt har 132 elever på Sveriges elitinnebandygymnasier besvarat enkäten. Könsfördelningen var 46 flickor och 86 pojkar. Enkäten bestod av både öppna och slutna frågor där eleverna fick besvara frågor som rörde deras idrottande idag samt idrottsbakgrund.Resultat: Elevernas födelsefördelning var spridd sett till hela populationen.

Förändringar av marknadsdesign och deras påverkan på balanshållningen i det svenska kraftsystemet : En kartläggning och analys av de balansansvarigas arbetsgång

A future expansion of wind power in the Nordic power system makes the balancing for the transmission system operator Svenska Kraftnät (SvK) more complicated. Up to the hour of delivery the balance responsible parties? (BRP) makes prognoses and plans, for consumption and production, to help maintain the balance in the electrical grid. How well this is accomplished is affected by the setup of the market design. Therefore SvK has proposed the following possible changes in market design: Increase the imbalance costsIntensify the regulation of imbalancesIncrease the temporal resolution on the different marketsPresent the prices for balancing power in real-timeModify the balancing market to simplify auction of consumption bidsA mapping over the BRPs? processes within planning and trading on the day-ahead, intra-day, and the balancing market has been performed in this thesis.

En analys av försörjningskedjan inom Jens S Transmission AB

Syftet med arbetet är att vi som oberoende part skall analysera företagets försörjningskedja. Företaget, Jens S Transmissioner AB, är ett grossistföretag, finns idag representerat i fyra nordiska länderna. Vi kommer att koncentrera denna analys till de största marknaderna som finns i Sverige och Danmark. Idag arbetar länderna till större del oberoende som enskilda företag men målet är att man skall öka samarbetet och integrera verksamheterna. Metoden vi har använt bygger på att vi först gör en individuell nulägesanalys av företagen och avslutar med att jämföra dem båda i en Gap-analys.

Möjligheter och hinder för aggregerad förbrukningsflexibilitet som en produkt på reglerkraftmarknaden

Electricity production from renewable energy resources such as wind energy and photovoltaics is variable. Integration of these intermittent resources into the electricity system leads to new challenges in how to manage imbalance between supply and demand on the grid.One way to meet these challenges is to develop so-called smart grid solutions. One idea, called demand response, is to adjust the amount or timing of energy consumption, e.g. by control of household appliances, to provide flexibility that could be used to balance the grid. In aggregate, when applied to many units across the system, large volumes of energy could be made available when needed and this grid flexibility can be used as a product on the electricity regulation market.Despite the potential benefits, the number of demand response bids is currently low.

Evaluation of Ectopar for the control of the poultry red mite Dermanyssus gallinae

The poultry red mite, Dermanyssus gallinae, is a common problem in poultry facilities, causing great discomfort for the hens and effecting the production economically. Few efficient acaricides are available and there is a need for new control methods since resistance has become a problem in some cases. The aim of this study was to evaluate the efficiency of the new liquid silica control agent Ectopar, on the poultry red mite. An initial in vitro test of Ectopar and its two components individually was performed, where live mites were sealed in together with filter paper impregnated with one of the three solutions prepared. The survival of the mites was thereafter recorded repeatedly during a period of 120 hours and compared to a control. For the field study, two poultry farms with different housing systems were used, one with furnished cages (farm 1) and one with a single tier floor system (farm 2).

Nipahvirus : patologi hos en nyupptäckt zoonos

Nipahvirus is most likely spread from bats to other species and causes lethal encephalitis in humans and respiratory illness in pigs. Different species are affected with varying severity but it seems to have an unprecedented zoonotic capacity and the humans affected either die or receive permanent brain damage. Full recovery is possible but very uncommon. Pigs that live and are bread in the areas that these bats frequent are constantly in danger of contracting pneumonias and meningitis and they can spread the virus further on to the people who work with the pigs and process their carcasses. These workers could then infect other humans in their immediate surroundings, their families for instance.

Anonymous ansikten : En undersökningar av några svenska dagstidningars konstruktioner av hackernätverket Anonymous

This study examines how a couple of Swedish daily newspapers construct the hacker network Anonymous, with an aim to discuss its possible effects. The question was: In which ways is the network Anonymous constructed in a few Swedish newspapers?                      26 articles from four chosen newspaper were analysed, but because of many similarities in content, only 10 were chosen for deep analysis. With Fairclough's model of critical discourse analysis as chosen method, constructions varying from the images of heroes to villains were found as a result. The most common construction was that of Anonymous as a threat, which was most often exaggerated compared to what actions were actually described in the texts.

Normativa värden för läppkraft hos barn mellan fem och tio år : Relaterat till bilabial stavelseproduktion

Lip force has been found to affect the ability to achieve satisfying speech production and swallowing. A normative value for lip force in adults has been measured to 15 Newton (N). Corresponding value for children measured with Lip Force Meter 100 (LF100) does not exist. In the current study lip force was measured in children between the ages of five and ten years. The aim of the study was to obtain normative values for children with typical development in separate age groups.

Integrering av cirkulationspump i slutväxel för CV90

Stridsfordon 90 är ett militärfordon som BAE Systems Hägglunds i Örnsköldsvik har utvecklat och startades att produceras år 1993. Fordonet vidareutvecklas och tillverkas än idag och på grund av ökade krav på skydd och eldkraft har fordonets tjänstevikt ökat kraftigt. Från den första versionen av fordonet, Mark 1 (ca 23 ton) till senaste versionen Mark 3 (ca 35 ton). Den ökade vikten påverkar en rad av olika komponenter i fordonet och dess prestanda men det är framförallt drivlina och fjädringssystem som påverkas mest. Fordonet har i sin drivlina slutväxlar som växlar ned rotationshastigheten från motorns transmission och överför på så vis ett ökat drivmoment ut till drivhjul och band.

IT och HR varför så krångligt? : En kvalitativ undersökning av ett personaladministrationssystem i ett landsting

IT exist and are needed in larger organisations today, this creates possibilities for new applications. It has become more frequent with IT within HRM which has developed new concepts like e-HRM and HRIS which links IT and HRM together. We have through qualitative content analysis of interviews investigated how IT-tools affect HR-workmanship. The purpose is to create a basis for describing how employees experience their work with HR within a PA-system. The basis of the PA-system will then answer if it contributes or limits the employees and their activities.
