Analys av off-design prestanda för ett absorptionskylsystem
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.
Taket och botten: tre amerikanska remakes av japanska förlagor
Det kommer konstant ut amerikanska nyinspelningar av andra länders filmer. Vad är det som skapar behovet av nyinspelningar? Vi har analyserat och jämfört tre japanska skräckfilmer med amerikanska nyfilmatiseringar (s.k. ?remakes?) för att försöka förstå vad det finns för kulturella särdrag i respektive länders gestaltning av filmberättartekniska konventioner av rum och tid och skillnader i kunskapsnivå om filmens händelser mellan protagonist och åskådare..
Växthusvävens fukttransmission ? Hur struktur och materialval påverkar växthusvävens fuktgenomsläpplighet
Växthus används för att ge ett bättre odlingsklimat åt grödor och växter. För ytterligare förbättring av förhållandena används växthusvävar som exempelvis kan reglera temperatur, fuktighet och ljustillförsel. Väven som behandlas i denna rapport är en så kallad energiväv som främst har till uppgift att minska energiåtgången vid uppvärmning.När väven är fördragen nattetid, ökar luftfuktigheten då grödorna avger fukt dygnet runt. Fukten kan kondenseras mot energiväven, vilket gör att det bildas droppar på väven som kan falla ned på växtligheten. Den höga luftfuktigheten kan medföra svampsjukdomar och i övrigt också bidra till att tillväxten avstannar.
Offentliganställda kvinnor, tid och stress : fem röster om tidsupplevelsens koppling till stress
Jeanine Basingers bok The World War II Combat Film presenterar en annars väldigt oupmärksammad genre, den amerikanska Andra Världskrigs-stridsfilmen. Utifrån den mall som Basinger beskriver i boken har jag här diskuterat och analyserat hur Saving Private Ryan håller sig till mallen som skapats av tidigare stridsfilmer. Mallen består i korthet av en mängd element som används genomgående i genren; såsom gruppen, hjälten, målet och fienden. Dessa element förekommer från den första andra världskrigs-stridsfilmen Bataan från 1943 och har konsoliderats och utvecklats sedan dess. Slutsatsen blir att även om SPR blivit känd som en nydanande och orginell film så är håller den sig nästan slaviskt till mallen, det enda som möjligt kan skilja den lite från andra filmer i genren är det ursprungliga målet, det är inte vanligt att ha ett såpass politiskt inkorrekt mål som att rädda en enda man..
Analys av energianvändningen i kvarteren Carolina och Jenny : en fallstudie
An energy study has been performed on two blocks in an area called Gävle Strand. The buildings are owned by a tenant-owner?s association called brf Carolina and were built by the company Skanska 2008. The builder as well as brf Carolina are pussled by the fact that electricity use is higher than expected while heating is less. Skanska is also very interested in finding out how much heat recovery from stale exhaust air through a geo-thermal heat pump is contributing to the general heating requirement and energy balance in four out of the ten buildings located on the properties.To find possible answers to the higher electricity use a literature survey on user behaviour was conducted.
Blomgren - en mönsterkollektion
This report is about the exam project; Blomgren- a collection ofpatterns. During eight weeks I have from the family Blomgren, whowas my grandfather?s family with siblings and parents, produced fivepatterns for textiles into interior and space. In addition to thefamily as an inspiration, I have taken into account of the collection?sname - as a word and the meaning of the word.
Stubblyftningens initiala effekt på emissioner av växthusgaser från en granmark i Småland :
In order to reduce greenhouse gas emissions from human activities fossil fuels will have to be replaced with renewable energy alternatives, such as bioenergy. Sweden has a great potential to produce bioenergy derived from forest products and there is currently a great interest within Sweden in using stumps for bioenergy production. However, the environmental consequences of the method need to be investigated before stump removal can be performed on a large scale. Swedish forest soils contain large carbon pools and a different land use may change conditions so that soils that presently act as sinks of carbon could potentially turn into sources of carbon release instead.
This study investigates the initial effects of stump harvesting on the emissions of three greenhouse gases, carbon dioxide, methane and nitrous oxide. The emissions were measured from the soil surface in a Norway spruce forest located in the southern part of Sweden.
Ett gårdsbesök : ger besöket någon kunskap om mjölkproduktion?
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas. The transport of pesticides used in the agricultural area in Sweden is monitored with continuous environmental supervision every year. During 2002-2008 an average of 10 pesticides were found in each sample and 40% of the samples contained substances with concentrations higher than the Water Quality Standards. Chemical risk management is normally based on single-test evaluations. A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.
Pålarna i Alvastra : En analys av möjliga använda huggverktyg vid byggandet av Alvastra pålbyggnad
This paper deals with the question of with witch tools the Alvastra pile dwelling was built. To reach a result I calculate the curvature on 29 stone axes, 8 double-edged axes and 21 simple-edged axes, used in the middle-neolithic in what today is Sweden. These results are then compared with two jams (the point in the pole where the axes edged stopped and left a mark) on two piles from Alvastra pile dwelling..
Narrativ i visuell media
Denna undersökning omfattar kamerans inverkan på narrativet i visuella medium. Syftet är att få en insikt i hur kunskap om kameratekniker och ?vinklar påverkar hur åskådaren uppfattar vad regissören vill förmedla, och undvika att fokus sätts på element i filmscener som riskerar att förvirra åskådaren. För att undersöka detta problemområde har litteratur om filmhistoria och kamerateknik använts för att sammanfatta kunskap om hur kameran skall användas, för att förmedla relevant information och bygga upp den effekt som regissören strävar efter. Informationen utifrån detta har därefter tjänat som utgångspunkt för att skapa en kort animerad film med rymdtema där kameran eftersträvar att leverera en konkret visuell upplevelse där vinklar används för att understryka vad varje scen vill förmedla.
Klimatförändringars påverkan på kulturmiljöer i Uppsala stad ur ett geovetenskapligt perspektiv
Cultural heritages are environments created by humans that are considered to have a conservation value for the posterity. They can be seen as one of society's non renewable resources. It is important to have knowledge of how cultural heritages are affected by future climate changes.The water flow in Uppsala is estimated to increase during winter and decrease during spring and summer. Precipitation will gradually increase as well as the intense short period precipitation. The average temperature is estimated to increase as well.
Informationsförmedlingen till Försäkringskassans handläggare
The main purpose of this master thesis is to study the information support by the head office of the Swedish social insurance office to its administrators. The thesis only focuses on information that concerns laws, regulations and instructions. The study is based on an interview with the head of the division of law at the social insurance head office and a questionnaire answered by administrators in four different counties. The purpose with the interview was to find out about the information strategy of the head office and in the questionnaire the administrators could describe their opinion of their information support. Our special interest was the information channels and how the administrators were able to absorb the essential information.
Planering och gestaltning för träning och motion
Aquatic organisms are usually not exposed to single substances but rather to mixtures of toxicants in streams located in agricultural areas.

A problem when assessing mixture toxicities is that the constituents and concentrations of pollutants in the environment vary greatly.
Känsla kontra information i fotokommunikation
Photography has a big role in information sharing today. Especially in the hotel
industry where it is the closest thing a customer can get to the product that
is being
sold. This study intends to find out how you can make use of rhetorical models
and
techniques of photography to enhance the communication skills of photos of hotel
rooms. The main focus was to understand the difference between informative and
emotional photographs and what consumers themselves focus on when choosing a
hotel, and also how to use the collected information to create a larger buying
interest
through hotel photography. Using previous research work and quantitative data
collection method, we have concluded that the informational and emotional
photography methods have obvious differences but also many similarities, and are
most effective used together and that the hotel consumer is more aware of the
images
influence then we assumed..
Koldioxidavgång vid ekologisk odling på organogen jord
The background of this work is the media discussion about the effect of cultivation on peatsoils on greenhouse gas emissions. It has been argued that row sown and intensivelycultivated crops such as carrots are more likely to emit carbon dioxide than for example grassleys. The association KRAV (an association promoting organic farming) shall, from this yearadapt their environmental policy to be more climate smart and have asked the question if thecultivation of some crops is more climate smart than others? Carbon dioxide emissions fromsoil are due to degradation of organic material and the rate is controlled by microbial activity.The microbial activity is determined by a variety of factors such as temperature, soil organicmatter quality and water content. I have measured the carbon dioxide emission from fourdifferent crops at two different farms.
