Hur påverkar byggnadsmaterial av stål en induktiv hörslingas fältstyrka samt frekvensgång?
This research analyzed differences in measurements of magnetic field strength and frequency response in five audio induction loops installed in rooms of wooden construction materials and five audio inductive loops installed in rooms of steel reinforced concrete constructions. The inductive loops were installed at floor level and the measurements were made at the listening height of 1.2m. Measurements of background noise, field strength and frequency response were made at fifteen different measurement points across the room. The research measurements showed that there are differences in field strength and frequency response between these two conditions, whether the audio induction loop is installed in a wooden construction or the audio induction loop is installed in a reinforced concrete construction. The results had a significance level of p=0,05..
Kroppsfett, genus och queer sexualitet : en undersökning av meningsskapande kring kroppar och fett i queera sammanhang
This essay examine the meaning produced around bodies and body fat in the queer community, but also in the surrounding straight community. The author has interviewed fat activists, and are using queertehory, to examine and analyze the relationship between body fat and the understanding and construction of sexuality and gender. The author concludes that even if norms around body shape and body fat are overlapping between the two contexts to some degree, they also differ. In the straight community, people with larger body shapes and sizes are punished, and encouraged to stay, or become, slim. However, in the queer community, ?fat? or bigger body sizes are not frowned upon in the same degree.
Kartläggning och analys av informationsflödet vid framtagning av ny produkt
Examensarbetet utfördes på företagets produktionsanläggning, där det produceras kundspecifika butiks- och restauranginredningar i mindre skala. Företaget har expanderat snabbt och relativt nyligen startat upp sin produktionsanläggning, vilket innebär att det finns goda förutsättningar för en god och mycket gynnsam framtida produktion men företaget är inte riktigt där än. Brister i både kommunikation, projektledning och konstruktion kan ses som några av grundorsakerna till de egentliga stora problemen i och under produktion.Syftet med examensarbetet är att analysera och kartlägga grundorsakerna till detta, samt ta fram förbättringsförslag som kan leda till att uppnå de framtida målen.Några förbättringsförslag har arbetats fram med hjälp av olika Lean verktyg, några exempel på dessa är rutiner och mallar för konstruktion. Dessa förslag har även testats på skarpa projekt och gett goda resultat både under projektets gång men även i efterhand vid utvärdering..
Logistik i byggbranschen : Fo?r fo?rba?ttrad arbetsmiljo? och effektivitet
Logistics and supply chain management in the construction sector is an area with great potential for improvements. Today, a lot of the workers time is spent on non-value adding activities. Research has shown that waste is a large proportion of the total production cost in building projects today.The purpose of this report is to analyze problems concerning logistics in the construction sector. Two of Skanska?s construction projects in Uppsala have been analyzed to identify problems.

Manligt och kvinnligt ledarskap inom byggbranschen : Skillnader och likheter mellan manliga och kvinnliga egenskaper i en mansdominerad bransch
In the construction industry the number of female managers is very low, only four percent (SCB, 2010). In fact, women with management positions has risen by six percentage overall, the last seven years (SCB, 2010). If women in managerial positions continue to grow at this rate, the proportion of women managers will be equal to that of male managers in 2033. More women are needed in the maledominated construction industry in particular because it is deemed that they have a different way of thinking and acting (Granér, 1994). Nelton (1991) believes that companies can take advantage of female managers to be more competitive on the market, the reason why is because women can see other possibilities when solving problems. Rapacioli (2010) argues that the recruitment of women into management positions not only benefits the individual itself but also the company. We have used a qualitative study with a deductive approach. Six respondents from the same company were interviewed, two of them have management positions and the other four were underemployed.The research question of this paper is: What differences and similarities are seen between male and female leadership in terms of their characteristics in the construction industry?The purpose of this paper is to examine similarities and differences in leadership in the construction industry where the focus is on the female and male characteristics. To fulfill our purpose we chose a qualitative study. We have interviewed six respondents at one company in the construction industry. Two of the six respondents have management positions and the remaining four are employed. In this paper we have concluded that there are some differences and similarities between men and women´s leadership in terms of their characteristics.
Mediakonstruktionen av den brottsliga invandrarkillen
This qualitative research is about how Swedish media constructs immigrants in articles. The focus of the study will lie on ten Swedish articles and how they stereotype immigrants, but the demarcation will be for young immigrant boys related to crimes. The purpose of this paper is to highlight how media achieves its goal to construct a group as inferior. This will be implemented with the help of articles from different newspapers that reported on immigrants who have committed crimes. We have chosen to look at different newspapers to see if there is a curtain pattern in the construction of immigrant boy.
Ständiga förbättringar på en akutmottagning
Studiens syfte är att kartlägga och analysera hur ständigt förbättringsarbete i dagligt arbete fungerar på en akutmottagning samt förutsättningar som möjliggör och hindrar detta förbättringsarbete. Den teoretiska referensramen består av tidigare forskning om förbättringsarbete, Lean Production, Kaizen, ständiga förbättringar samt förutsättningar som påverkar dessa ständiga förbättringar. Metoden som använts för att besvara syftet är en kvalitativ fallstudie med semistrukturerade intervjuer.I slutsatsen framgår det att det är chefernas inställning och engagemang kring ständiga förbättringar som driver arbetet framåt, vilket smittar av sig på medarbetarna. En tro på att ständiga förbättringar långsiktigt kan utveckla verksamheten i en positiv riktning. Det som hindrar är framförallt de kontextuella faktorerna tid och resurser.
ENERGIANVÄNDING PÅ BYGGARBETSPLATSER : Analys av införandet av energieffektiva byggetableringar
This report is the final step in the Bachelor of Science program in Building Construction Engineering, Department of Engineering Sciences, Uppsala University.The purpose of this study is to highlight the difficulties and possibilities that could involve the introduction of new energy efficient technologies and changing work around this technology. This study focuses on energy use at a construction site or other temporary workplace where so-called portacabins are in place to address the need for temporary facilities.The method for obtaining knowledge on the subject was mainly interviews with site managers working in Svevia AB's various activities. In conjunction with the interviews I visited construction sites and portacabins if it was possible.My most important suggestion to Svevia AB concerns a better organization in order to make poratacabins more efficient on energy and costs. The company should also evaluate and monitor the energy efficient portacabins that are in operation.Expected energy savings of new technology may not materialize if there are gaps in information, education, technical services and technical maintenance. It is very important to utilize the experiences of new technology.
Grundläggning med cellglas : En studie av byggtid och lönsamhet
This report describes a new foundation method and compares it with a traditional founding of concrete. This new method is called the Koljern technique and uses cellular glass which is called Foamglas. The Foamglas is compounded to founding elements by lightweight steel beams. Foamglas is an insulation material with high compressive strength, and is rot, insect, vermin and acid proof. The cellular glass is also fire proof and watertight, which makes it a very good construction material.The report contains a study of a number of cases for which the Koljern technique is compared with a foundation of concrete.
Utredning av tvättning vid Volvo CE Components
Detta examensarbete är resultatet av en utredning av tvättning och rengöring av produkter som tillverkas på Volvo Construction Equipment Components AB i Eskilstuna. Arbetet är uppdelat på två huvudområden, tvättning i processen samt slutgiltig renhet. Skillnaderna mellan dessa är framförallt att det finns fastställda krav på den slutgiltiga renheten för artiklarna men en motsvarande märkning saknas för de olika tillverkningsstegen. Idag tvättas ungefär 70% av TMAs artiklar i en central tvättstation. I och med detta uppstår en hel del problem med ledtider och kvalitet.
Ljusföroreningar i stadsmiljö : Hur kan ljusföroreningar förebyggas vid nybyggnation?
Light pollution in urban areas - How to prevent light pollution at construction Jakob Sjöling Light pollution is a relatively new but rapidly growing form of pollution. Society's increasing demand for light coupled with the pace at which lighting technology evolves is accelerating that growth. The purpose of this study was to analyse how the construction industry plan and design outdoor lighting when erecting new buildings, specifically with regards to the issue of light pollution. It also investigated how local authorities work with these issues during urban planning. In both cases special interest was placed in ways to improve the planning and use of outdoor lighting in order to minimize light pollution.
Genomarbetade förfrågningsunderlag medför tids- och kostnadsbesparingar : En studie över handlingars påverkan i byggskedet
In order for construction projects to be completed within the specified time limit while at the same time be financially sustainable it requires thorough preparation and an extensive planning. Most essential is the groundwork and the design that determines the project's progress. There are many aspects to consider in order to avoid inconveniences such as delay, litigation, unexpected cost etcetera. If mistakes are made in an early stage it is very likely that the error will follow the process and become an expensive correction cost towards the later part of the project. In other words, it is expensive to rectify defects later on.
Functional Cuts
Our everyday life is becoming more active and the activities we perform influence the way we dress. Due to an increase in activities undertaken in an urban environment, demands are changing and the need for active wear that meets the new demands follow suit. The four characters represented in the research can be seen as a reflection of the functional features needed, including base layer, mid layer/insulation and shell.Despite the increase in activities, most of our clothes are still constructed on static dummies or drafted on a table in 2D and the main developments within the active sportswear field is driven by material innovation. By creating garments on a body in movement, my aim is to develop new functions and expression in active sportswear through construction.Construction methods in active sportswear are examined and understood through observations and reconstructions and constitute the foundation of a study of movement for a design recovery.The movement and features required for leading an active urban life sets the direction of the development of new func- tional garments. A series of trial and error sessions and draping fabric on a live model in movement created the prototypes used in functionality tests to establish their feasibility.
