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.

Bankers syn på ändringar av aktiekapital, revisionsplikt och redovisning : En fallstudie av svenska storbanker i Karlstads kommun
The amendment of a law which is expected to come may well have a significant impact on the Swedish real-estate broke market. The law change will probably have an effect in the number of ways real-estate brokers will compete as a result of the increasing variety of services offered. In order to gain competitive advantages brokers must be at the forefront in the development regarding the changing market. To do so requires that the company chooses an appropriate range of peripheral services that are profitable. The problem is to choose the ?right? services to convey. The purpose of this paper is to describe the services that are in demand for transmission and how the agents can work to meet the demand of this new market.
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.
Faktorer som stör patientens sömn under sjukhusvistelsen samt sjuksköterskans omvårdnadsåtgärder för att främja sömnen : En litteraturstudie

Studies have shown that patients found it difficult to sleep during thehospital stay and it turned out to be several factors that disturbed the sleep during the night.The nurse should note the patient?s need for sleep and take into account environmental andother sleep disturbances to be able to implement nursing interventions. Purpose: The purposeof this study was to elucidate the factors that interfere with patient?s sleep duringhospitalization and nursing care to promote the patient?s ability to sleep.
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.
The sound of scilence : Hur tyst kommunikation kan gestaltas i klassrum
Fo?religgande uppsats handlar om den tysta kommunikationen som gestaltas i klassrum av la?rare och elever i skolan. Syftet har varit att utifra?n tre valda aspekter; tyst kunskap, tysta relationer och tysta redskap analysera och kartla?gga den tysta kommunikationens uttryck. Genom en systematisk litteraturstudie besvaras fra?gesta?llningar ro?rande vardera ovan na?mnda aspekter na?mligen; Hur kan tyst kunskap komma till uttryck hos la?rare, vad kan ske i tysta relationer mellan la?rare ? elev och elev ? elev samt vad kan kropp respektive miljo? som redskap ha fo?r betydelse fo?r kommunikationen.
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.
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.
Hur inverkar kontrollbordet på frekvenskurvan vid lyssningsposition i kontrollrummet när placeringar av högtalaren och lyssningsposition placerats efter ITU-R BS.1116-1 rekommendation?
The acoustics in a control room is a complicated phenomenon. Early reflections, reverberation time and area in the room are some of the problems. This report is about the reflection on the mixing console in a control room. The control room being built, these reflections are difficult to take into consideration since the mixing console is one of the very last items you place in the room. This report will explain three main measurements that were done in order to get the answer to the following question: Does the mixing console interfere the frequency curve at listening position? Three measurements were done and the difference between the measurements was that the microphone and the loudspeakers were placed in different places in the control room.
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.
Dark Side of Wonderland : en kort 2D-animation med syfte att väcka intresse för en online serietidning
My objective for this project was to create a short but thrilling 2D-animation intended as promotion for an online comic book. The purpose of the project was to learn more about animation and graphics, to further my artistic skills and to learn how to work in Adobe After Effects. I also wanted to learn more about scheduling, project methods and how to handle stress. During the ten weeks of the project I have created the story, the storyboard, the character design, the backgrounds and the animation. The voice over was recorded with the help of a fellow student who also made the music and the sound effects.
Åtgärder för att minimera trafikbullers påverkan på ett rekreationsområde
The aim of this inquiry was to investigate the most appropriate measures to reduce noise impacts from road traffic on the Nydala recreational area in Umeå municipality due to the planned re-routing of the E4 motorway to an existing road along this area. The sound environment is an important part in the experience when we are visiting recreational areas. Noise is not only disturbing; the liberty from unwanted sounds also allows us to perceive natural sounds that are a benefit for the cultural experience. Therefore it is important to take actions to protect this well used area from traffic noise. The reasonable options to avoid noise impact in this case are to lower the speed limit, using a noise reducing coating or use noise protection screens and walls.
Scenografi till teaterpjäsen Om det här varit en Feelgoodfilm
In the project, my ambition was to make a stage design for theater withteenagers as target group. I have worked with the musical theater groupTheater ACTA in Gothenburg and independently from scripts, interpretedand shaped an outline for the basis of the set design of the play?s differentelements. The play, If this was a feel-good movie, is written by Elin Frostand Anna Lundholm, two members of Theater ACTA. The story is aboutthree people in their twenties with different relationships to each other andone week that would change their lives.
