Bättre arbetsberedningar med hjälp av BIM : Hur de kan utformas för implementering av BIM

During the past years Building Information Modelling (BIM), which is a digital way to work, has begun to spread amongst the parts of the construction process. At the construction phase the larger companies has started using the new way to work. This expansion has not been developed amongst smaller companies leading to the purpose of this report, to investigate in which ways the smaller companies can implement BIM by changing their way to work. The thesis is delimited to work preperations with the objective to define how the work preperations should be structured to enable the implementation of BIM. To achieve the objective of the report, information about the subject has been collected by interviews and literature studies.

Detta examensarbete försöker svara på frågan hur man optimerar värmespridningen från en oljefylld elradiator. Flera teorier används för att försöka svara på denna fråga, och slutligen ges ett förslag på en oljefylld elradiator, som enligt författarnas undersökningar borde vara optimerad för värmespridning..

Urban Vindkraft : ett nytt element i bebyggd miljö?

This paper aims to explore the phenomenon urban wind energy, its visual effect on built environment and the factors that affect the opinion towards new elements in the city. A place study of the city Gävle serves as a complement to the theoretical part of the paper. The theoretical discussion opens with an account for the technical and economical conditions of urban wind energy. It presents the technical basics, different types of turbines and a discussion occurring wind related techniques in built environment. Today, the knowledge of how the wind moves and acts in the rural landscape is quite good.

Passivhus - lönsamt eller ej? : En jämförelse mellan ett passivhus och ett konventionellt hus

As a result of increased energy prices more and more energy-efficient homes are coveted. An energy-efficient alternative is passive houses, which is characterized by an extremely well insulated building envelope that recovers the heat without the use of radiators or under floor heating. But a passive house requires a higher investment cost than a conventional building project, since it will require more construction materials, training of construction workers, greater land area, and long construction period. But the lower operating cost expects to pay back the higher cost of investment. We therefore question how profitable a passive house is in relation to houses built according to modern conventional building techniques.The aim of our study is to investigate the viability of passive houses compared to convent­ional houses.

Varför BIM?

Is the new technology always the best? This final project tries to determine if BIM is the melody of today, or if traditional 2D drawing is recommended. Perhaps a compromise is necessary, utilizing both methods.In order to answer this question, different views from the industry have been retrieved through reports, producers of software and users. The approach has consisted in building a 3D model of the school Råslättsskolan, house 01, along with interviews with people involved in the building process.When working in 2D it is hard to include the third dimension, mistakes are done and collisions happen that must be corrected, in most cases at the construction site. BIM is an incredible help since the model allows you to detect collisions and correct them.

Utveckling av biopsiinstrument : Instrumenthållare för skruvnålsbiopsi

This Master Thesis has been carried out in cooperation with Ursus Medical AB (URSUS) which markets, assembles and sells the Rotex Screw Needle Biopsy Instrument ®. The instrument is delivered with an instrument holder. Customers had expressed dissatisfaction over that they needed to use two hands during a biopsy procedure, which resulted in a project to develop a new instrument holder.The project aim was to create concepts for how the new instrument holder should be designed, with focus on the mechanics. The new instrument holder would build on the existing basic principle that the screw needle and the cannula were screwed into the tissue. The thesis work would result in a technical solution and a functional prototype of the chosen concept.To achieve this, a generic product development processes were used and began with a comprehensive literature review.

I regnbågens skugga : En analys av kommuners diskurser kring våld inom hbt-relationer

The purpose of this study is to investigate how the Swedish municipal welfare system, in their capacity as discourse makers, construct Intimate Partner Violence (IPV) in the relationships of Lesbian, Gay, Bisexual and Transgender (LGBT) people. A discourse analysis of their official plans of action regarding IPV and the information directed towards their citizens through their webpages showed that the discourse surrounding IPV revealed a gender dichotomy, where the victim was mainly constructed as being female and the perpetrator as male. As a consequence of this, gay and bisexual men were rendered invisible from the discourse surrounding victims of IPV, although they could be included in the construction of perpetrators of it. Lesbian and bisexual women were often included in the understanding of victims of IPV, but in the discourse surrounding perpetrators of it they were made invisible. The discourse about IPV also excluded the experiences and vulnerability of people who identify as being transgendered.

Varför uppförs så få bostadsrätter med passivhusstandard i Sverige? : En fallstudie mellan ett passivhus- och en konventionell fastighet

Abstract Background: In 1997 the Kyoto Protocol was signed, it?s an international agreement which is aimed to reduce greenhouse gas emissions. Sweden's goal is to reduce energy using in buildings with 20 percent by 2020 and 50 percent by 2050. This is a comparison with levels from 1995 (Glad, 2006). For Sweden to be able to reach its goals, they need to construct more low-energy buildings (Åhman, Wahlström & Lundblad, 2010).

Hur väl integreras ekobygglösningar hos bostadsbyggande byggherrar

Vi lever idag under ett klimathot som påverkar oss alla. I ljuset av detta har byggbranschen valt att börja ställa om mot en mer hållbar bransch. Under tiden har även ekohus och ekobyar byggts upp som ett alternativ sätt att bo suntSyftet med detta arbete har varit att undersöka vilka val som byggherrar/beställare gör vid projektering av nya bostäder. Jag har valt att inte titta på energianvändningen utan fokuserat på vilka miljömässiga aspekter som återfinns i arbetssätten kring projekteringen av bostadshusFör att ta reda på vilka val som kunde anses som ekologiska/miljömässiga gjordes först en litteraturstudie. Sedan gjordes en enkätundersökning där utvalda företag fick svara på bl.a.

Eldens arkitektur : En studie av de medeltida varmluftsugnarna och deras betydelse

AbstractThis thesis examines and discusses a sample of the medieval hypocausts (stone-heating ovens) in the Baltic area. The medieval construction is thoroughly explained as well as the antique hypocaust in order to establish a base for the following discussion. The medieval hypocaust has been almost forgotten for a long period of time. The last time someone dealt with this category of finds were in the 1960?s by Swedish archaeologist Iwar Andersson and in the 1970?s by Danish archaeologist Johannes Hertz.

Bilder av föräldraskap : En studie om hur föräldraskap konstrueras i barnhälsovårdens föräldragrupper

The parental education groups are an activity that attracts the majority of all couples that awaits their first child. Therefore this is a forum with strong influence on the formulation of the parenting. The aim of the study was to examine how parental education within Swedish child health care, affects the construction and shaping of parenthood. We have also studied this from a gender perspective. The starting point for our understanding of parenting is that it is socially constructed.

Implementering av BIM i ett projektledningsföretag inom byggindustrin : Implementation of BIM in a project management company within construction industry

Syftet med rapporten är att skapa en förståelse om vad BIM är och undersöka vad BIM för med sig i projekteringen. Det som kommer behandlas är BIM-samordnarens uppgifter, de olika negativa aspekter som påträffats vid användandet av BIM samt en presentation av olika program så kallade verktyg som används vid BIM-projektering. .

Hipsterism - Subkulturell Renässans

Uppsatsen är ett försök att applicera kulturvetenskaplig teori på en kontemporär subkultur. På så sätt kan den avkodas och dess kopplingar till samhällstendenser kan belysas. Tesen är att hipsterismen innehåller element som utmanar sättet vi vanligtvis tolkar och förstår ungdomskulturer på. Vidare visar forskningen att hipsterismen är ett resultat av nästan 40 år av nyliberal kapitalistisk utveckling, kombinerat med gentrifiering, konsumtionsvanor, kulturellt kapital och subkultur..

Liszt och Alkan: Den virtuosa pianoetyden : Övningsstycke eller muterat monster?

Anders Rådén: Liszt & Alkan: the virtuoso piano study ? practice study or monstrous mutation? Uppsala: Musikvetenskap, 1998. C-uppsats (60 p).The purpose of this essay is to analyse a selection of studies by Franz Liszt (1811-1886) and Charles- Valentin Alkan (1813-1888). Can they be definedas practice studies, or are they reshaped in such a manner, as to establish a larger form reminiscent of the concert study? First of all, typical study characteristics of this time period are determined, then such characteristics are looked for in three of either Liszt's and Alkan's studies (from Douze grandes études S137 and Douze études dans les tons mineurs Op.
