BIM Building Information Model : Hinder & Drivkraft

The  construction  industry  is  a  costly  business  such  in  respect  of  capital  for  most construction defects which then require rework, tear down and rebuild again. This study is  meaningful  awareness  of  tools  that  can  reduce  this  best  through  communication  and information sharing between the parties.  The  construction  industry  is  known  as  temporary  projects  organizations,  where  the construction  project  consists  of  several  actors  who  have  to  communicate  and  share information  between  them  to  avoid  mistakes  later  in  the  build  time.  These  actors  are bounded together thus for the duration of the project, then broken when the project has reached its end. The challenge here is for these actors to apply a tool that can help and simplify communications, information sharing, and perhaps the most important aspect is to  create  a  routine  for  the  association  and  the  shattering  of  these  actors.  To  implement such  behavior  using  a  tool  such  as  BIM  in  the  industry  whose  size  perhaps  is indescribable may be a very hard task.  BIM (Building Information Model) could be seen as the solution to this problem because it  acts  as  a  portal  where  the  actors  involved  must  sign  in  and  communicate,  share information, and eventually create a behavior, a routine for this association and division of  the  actors  following  the  end  of  the  project.  The  technology  could  help  the  involved from  the  beginning  of  the  project,  already  in  the  model  stage,  break  down  and  prevent any construction barriers when the building has been placed in the works.

Kvinnors drivkrafter för att lämna en kriminell livsstil : val, uppbrott och förändring

The purpose of this essay is to analyse the descriptions of young girls' experiences of internet contacts, which have led up to sexual abuse. The aim is to give additional understanding and knowledge concerning grooming.       Grooming means that somebody gets in contact with someone else with the intention of committing sexual violations at a later stage. In most cases this concerns adults who contact children. We have chosen to confine ourselves to focusing on the grooming on internet that has happened to girls. By means of thematic analyses of texts from the books Jag kände mig speciell, grooming på internet, 2012 and Alexandramannen, vår tids största nätsexhärva, 2009, we have found certain themes and linked them up with previous research-work and also theory of social psychology.

Återvinning av näringsämnen från hushållsspillvatten med omvänd osmos

Hammarby Sjöstad is a new district in Stockholm with high environmental standard. Stockholm Water Company evaluates a local wastewater treatment plant with cutting edge technology. The first step is an experimental treatment plant (Sjöstadsverket) with four parallel lines of treatment, each with a capacity to treat wastewater from 150 persons. Within the membrane technology subproject the possibility of using reverse osmosis (usually called RO) to regain nutrients is examined.Reverse osmosis separates the incoming water in a clean permeate and a concentrate that, as the name indicates, is a more concentrated version of the incoming water. Using this method in wastewater treatment, a solution high in nutrients can be obtained without the use of chemical precipitation agent and with no production of sludge.

Utvärdering av befintliga passivhus : En byggnadsfysikalisk bedömning och mätningar om temperatur, och fukt analys på ytterväggarna

Energy price are on the way up to a high level that will not diminish in the future make us to focus more on the sustainable development for a better solution of residential houses. Passive house or low energy housing are one of the solution to make residential more environment friendly, in same time it´s a financial security using less energy, and saving money. The last 10 years in Germany and all around Europe the concept of passive house been developed, and people aim to know more about these concept that leading the market more attractive for passive houses. A passive house is a well designed building highly insulated and air tight with mechanical ventilated system for the whole building envelope that minimizes the use of energy for heating [1].The housing company Mimer has chosen to invest in low energy consumption in every new housing project.  These future plan projects are decided to use less than 75 kwh per square meter annually in purchased energy [2].This thesis is about new constructed passive houses, and focuses on the evaluations of the temperature, and moisture condition for attic, external walls and joist.

När spelen blev farliga: konstruktionen av dataspel som ett socialt problem i svensk press 2000-2006

This essay focuses on the construction of so called "computer game addiction" or "computer game abuse" in the Swedish press during 2000-2006. During this period computer game addiction went from an obscure phenomenon to a legit reason for the involuntary commitment of a fourteen-year-old.The study's theory is based on several social constructionist ideas. Kitsuse and Spector's theories about constructing social problems as claims-making activities are used for understanding the actions of the individual and groups involved. Hewitt and Hall's article about quasi-theory is used to explain the construction of explainations for the new social phenomenon. Blumer's five-stage model is used for categorizing the construction of the new social problem.

Set Based Concurrent Engineering : En undersökning för Scania CV AB

This Master thesis has been carried out at Scania CV AB in Södertälje, in collaboration withKTH, The Royal Institute of Technology, Stockholm. The focus of this Master thesis isSetBased Concurrent Engineering(SBCE), with the purpose of answering the questions: what isSBCE, how does it work, and for what purposes is it applied.It was early established thatSBCE is often included as a part of Lean product development,which in its turn is often related to Toyota?s way of working. TheSBCE method includesworking with multiple solutions in parallel, eliminating weak alternatives throughout thewhole process. In opposite to a conventional product development process, where it iscommon one at an early stage tries to identify and choose the most promising alternative.Despite the appearance ofSBCE as a resource consuming method, figures from Toyotaindicates the opposite, thatSBCE is in fact a very effective way of working compared to othermore traditional methods.The process of this Master thesis was divided into three phases.
