Ljudreducering av värmepump

This degree project handles acoustic measurements of the heat pump EcoAir 107, made by Enertech CTC AB. The sound from the three sound sources of the heat pump, fan, compressor and four way valve, have been measured to find out how they affect the total sound level of the product.Measures to attenuate the sound level have been developed and tested. By comparing these with the sound of the heat pump, in its original state, we have found out the measures which have best effects.The best attenuating measures came to be: taped openings and holes around the compressor space, isolating the top and the bottom of the whole construction, support of the fan bottom part and shielding of the sound source with a screen at a distance of 110 mmThese measures have been tested together and an average attenuation of the total sound level with 3,9 dB have been accomplished. In the front of the fan where the continuous sound is the strongest, the attenuation was 4,7 dB.This project is meant to be used as a guide by Enertech CTC AB:s during their future developing process..

GIS-program för ruttplanering. En studie av nyttjandet av GIS-program för ruttplanering inom tekniska förvaltningar bland kommunder i västra Sverige

This report is a study in voltagelevel in connection with regeneration of brake energy from the tramtype M31 in Gothenburg.In the act of braking, the tram M31 uses electrical braking where the electrical motors generates energy and if possible send it back to the overheadline, where other trams in the nearby can use this regenerated energy for its own driving force. In cases where no other energyconsumers are located in the same section, there is a resistance witch task is to convert this energy into heat. The regulation of this resistance appears to cause an increase in the voltagelevel into far too high levels.Investigations of the trams regulationequipment and its construction have been done. Further have measurements on the overheadline been performed in order to map the voltagevariations during a longer period of time.The result have been showing that the voltagelevel during regeneration often is as high as 880V-920V, more extreme values have not been observed in a large scale. The values are especially high compared to the nominal voltagelevel.

Tillit, spelar det någon roll? En studie av tillit och individuella organisatoriska responser vid arbetsrelaterat missnöje

The aim of this qualitative study was to explore which inner conceptions about the abused older women the professional social workers had and how they experienced the enconter of an abused old woman in an intimate partner relation. The theoretical background is social construction by Berger and Luckmann. This theory was uset to analyze the transcribed interviews. This study is based on nine interviews with five professionals in social services, three volunteers from the voluntary sector and one social worker who worked in a community based support group for abused older women. The result of this study shows that older women were often abused, by a relative they were dependent on, in their home.

Exil hederskultur-ett narrativ

Drawing on a broad theoretical framework that includes theories about globalisation and honourculture, this thesis aim is to demonstrate that globalisation and honourculture, constitute a conceptual network, i.e a structural relational matrix in which concepts are embedded. Being part of conceptual network, these concepts are related to each other ontologically. The idea of conceptual network, and the thesis as a whole, draw upon what has been called ?relational perspective?This study aims to show the impact of globalisation on honourculture. The study shows the importance of narrative in the construction of discursive boundaries.

Hyperverklighet och gränssnitt : Gymnasieungdomars verklighets- och identitets- konstruktion i gränssnittet mellan varandra, internet och skolan

This study investigates the internet habits of students in the Swedish gymnasium. The part that internet plays in their lives and their attitude towards the educational system is reflected upon the philosophical background that stretches from Kant to postmodern philosophers such as Baudrillard. The aim is to create knowledge about how the social aspects of the internet affects their concepts of reality and their own and others identities. The method used for the collection of empirical data has been semi-structured interviews, preformed with students in a Swedish gymnasium. The data is then interpreted against the theoretical and philosophical background.

Tillbaka till framtiden : Förhållningssätt till framtiden och stadsbilder i 1900-talets science fiction-litteratur

The purpose of this paper is to develop an idea about geography in literature and through the study of science fiction literature examine the ?future city?. With the perspective that the city is a social construction and through the use of discourse theory, I have tried to emphasize how the future city is a representation of cultural discourses and in what way geography in literature can be used to increase our understanding of urban places. My intention with this paper has also been to find a way to connect the fictional future city with today?s urban planning discussion about the future city.

Ett bostadshus i prefabricerad trästomme : Ett gestaltningsarbete anpassat efter volymelementsbyggande

Den här rapporten är en sammanställning av ett gestaltningsarbete där ett bostadshus i 5 våningar projekterats fram. Huset i fråga har anpassats till att kunna byggas med prefabricerade volymelement och enbart i stommaterialet trä. Prefabricerade volymelement är färdigbyggda rumsenheter, tillverkade på fabrik. Dessa kan vara så pass färdigställda att de levereras till en byggarbetsplats med färdig fasad och fast inredning. Eftersom arbetet baserats på volymelementsbyggande, har projektering skett efter de villkor och den byggteknik som då tillämpas.

Vad gör barnen i byggrummet? : En studie om pedagogens roll vid bygg och konstruktion i förskolan

Syftet med undersökningen var att undersöka hur barn bygger utifrån en inspirationsbild samt om barnen lär sig mer då de utmanas av en pedagog. Undersökningen genomfördes med hjälp av observationer av barn på en förskoleavdelning där samtliga barn var tre år gamla.  Resultatet visade att de flesta barnen byggde vertikalt. Endast ett barn valde att bygga horisontellt och använde inspirationsbilden som underlag till sitt bygge. Resultatet visade även att det har stor betydelse om det finns en pedagog närvarande som utmanar barnen vid bygg och konstruktionslek och kan synliggöra deras lärande. Skillnaden i barnens byggande när de blev utmanande av en pedagog var att de använde sig av flera byggklossar när de byggde samt av flera olika geometriska former på byggklossarna..

Vad är problemet? - om konstruktionen av äldre invandrare som problem inom vård och omsorg.

The purpose of this essay was to see how the construction of elderly immigrants as a problem in healthcare and elderly care has been described in the relevant literature. In the course of doing so I tried to answer the following questions; What is said to be the expected problems or difficulties in work with eldely immigrants? How are the expected members of the problemgroup defined and identified? Whos perspective dominates the description of the problem, the users or the investigators? These questions were hard to answer and I had to conclude that the problem was not clearly defined; there was only an assumption of a problem. This, however, has not been a hindrance in the category of elderly immigrants being claimed to be a group with problems that need research and further investigation. The dominating perspective is that of the investigators as they are the ones who define and identify who is a part of the problemgroup..

Masshantering av schaktmassor : en jämförelse mellan traditionell masshantering och GPS-styrd masshantering i realtid

The purpose of this report is to analyze the advantages of using programme software to monitor masshauling instead of using the conventional method. A comparsion between different programs will also be conducted in an attempt to determine the most affordable. This report is written for NCC Construction AB to help them choose a software most fitting for future projects.The report is based upon literature such as information taken from the developers website, existing reports with similar context, interviews with sellers of the software and interviews with people working in the building sector.The result of this report shows that there are several advantages with investing in a software that helps the management of a project and that it is something that should be taken under consideration instead of the existing method. Topcon is a clear favorite following the inquiries comparisons as done, when they deliver a complete system and not only a supplement to the current approach. Scanlaser are just in the beginning of its development, and is so far only out with an early version of the software, while Topcon has been brought further in development and therefore has more features in the program.

SLASH : en kvalitativ undersökning om vad homoerotisk fanfiction kan vara ett uttryck för

The following study is a qualitative combination of textual analysis and interviews concerning the subject of slashfiction. Slash is a sub-category to fanfiction, which essentially means non-professionally authored short stories about already existing characters and environments, for example from TV-shows, movies or books. These stories are available on the internet. The main point is to pair two of the male characters together in a sexual relationship. According to previous studies, 90 percent of all fanfiction writers are female and this percentage is probably even higher when it comes to slash.I have looked into what these stories can be an expression of, by analyzing the construction of gender, sexuality and relationships using the following three questions:Is slash a quest for an ideal equal and romantic relationship?Do these stories represent a resistance against established norms regarding gender and sexuality?What role does transcendence of boundaries play in slash? I have used stories that are derived from the American TV show Supernatural, which generally try to explore the relationship between its protagonists, the brothers Sam and Dean Winchester.  The result gives a somewhat divided picture of slash, as some stories clearly break with traditional gender norms while others seem to uphold them..

PLATSCHEFENS FÖRMÅGA ATT ÖKA PRODUKTIVITETEN - en jämförande studie av fyra arbetsplatser hos Peab -

studier visar en låg produktivitet jämfört med andra branscher men också komplexiteten av produktivitetsmätningar. Syftet med rapporten är att undersöka platschefens roll och vilka faktorer som påverkar förmågan att få ut produktiviteten på en byggarbetsplats. Fallstudien genomfördes på fyra av Peabs projekt och frågeställningen besvarades med hjälp av kvalitativa och kvantitativa metoder i form av intervjuer och enkätundersökningar. Vidare undersöks produktivitetspåverkande faktorer såsom kommunikation, motivation, kompetens och samarbete. Vid jämförelse används en incitamentkvot som ställs i relation till enkätundersökningarna och intervjuerna.Resultatet visar tydliga skillnader mellan platschefernas förmågor, arbetssätt och egenskaper som leder till en skillnad i produktivitet på arbetsplatserna.Slutsatsen visar vilka egenskaper och arbetssätt som tenderar i att ge en hög produktivitet..
