Effektivisering av ventilationsprojekt : Bravida Filial Uppsala
In recent years the construction industry has been exposed to increased time pressure which has resulted in a higher amount of wastage. Today 35 % of all construction projects in Sweden is "wasted". Time pressure has risen due to increased competition on the market, with more actors entering the construction business, therefore profit margins decreased which has led to a more pressing need for decreasing the amount of wastage.Bravida is Scandinavia's largest supplier of installations and provides specialist services in electrical installations (heating and sanitation), and ventilation. Mahdi Bawaqneh's task was to investigate where, how and why wastage occurs in the company's projects and how to prevent such wastage. The thesis covers the subjects of lean production, communication in projects and planning of projects.
Dimensionering av bärverk av stål : En jämförelse mellan Eurokod och BKR
The design regulations of Boverket (BKR) have long been the mandatory standard for construction design in Sweden. However from the end of the year 2010, the BKR will be replaced by the European standard Eurocode (EC). The transition to EC has been delayed and it is not until the second of May 2011 that the use of EC will be mandatory. Because EC and BKR differ from each other it is highly interesting to investigate and explain these differences.The purpose of the thesis is to compare the two standards and investigate how they give different results or not for the dimensioning of structures of steel with associated loads. The current project HVC (Pets Science Center) in Uppsala is used as a model for the design of the steel structure used in this study.
Konstruktion av 6:e axel på 5-axligportalfräsmaskin
During springterm 2010 Erik Persson and Magnus Hansson performed their ThesisWork with DIAB Laholm, in Hallands County for University of Halmstad.The project has been a product development project without exterior customers. Thusit had a great emphasis on functionality and less emphasis on marketing and such.This reflects the ambition to develop machinery to be used within the productionfacilities of DIAB Laholm, not to be sold to exterior customers.Main objective has been to create machinery which enables the production ofrotational symmetric work pieces within a NC-milling machine with 5 axles. Thework pieces milled will be made of DIAB?s material Divyncell with varyingdensities.The project has followed Fredy Olssons method involving Principal ? Primary ?Manufacturing constructions. However a complete manufacturing construction hasnot been made since DIAB just wanted a good Primary construction which will serveas a base for finishing touches at DIAB.By the end of the project material including calculations has been sent to DIAB andthey will finish the work and manufacture the machine if they find economic viabilityin this.The work method has been suited for this by several reasons, it was created withthese projects in mind and it?s also the method most familiar to us..
Samtalet på Facebook : En studie om IKEA Sveriges kommunikation i sociala medier
IntroductionIn this study, we have explained the complexities of social media, as it is still a relatively unexplored area. With the rapidly growing use of social media in recent years, companies have chosen to establish themselves in social networks to advertise themselves and communicate with their customers. In this study we analyze IKEA Sweden and their use of social media on the national market, where focus lies upon IKEA Sweden Facebook-page. The study intends to find out how the company uses social media as a marketing and communication tool and also analyzes the relations and conversations that occur on the Facebook-page. Purpose and research questionsThe purpose of the study was to gain a deeper understanding of how a large Swedish company as IKEA has chosen to use social media and how it's perceived by them. We also intended to find out how IKEA Sweden uses social media in their daily work and how the company communicates through this media channel.

Passivhus - En undersökning om varför det inte byggs fler passivhus i Sverige
This thesis tries to clarify why more houses such as passive houses is not built and at the same time the differences is described with the conventional construction as a starting point. Sweden has set environmental objectives to reduce energy consumption in buildings by 50 percent by the year 2050 compared to 1995. The passivehouse concept could have a significant role, particularly in the reconstruction of buildings with high energy consumption. For sustainable building the passivehouse technology is an economically viable concept while benefiting the environment. Initially an introduction is given of the background to the problem, purpose and objective of the thesis.
Ägarlägenheter : - framtidens investering?
AbstractBachelors thesis, Bygg och fastighetsekonomprogrammet vid Högskolan i Halmstad Vårterminen 2009Authors: Emma Stenberg och Emma SvenssonTutor: Sven-Ola CarlssonTitle: Ägarlägenheter - en framtida investering Background and problemThe concept of owner?s apartment has been discussed in Sweden since the 19th century. It was not until the first of may 2009 that it got legislated to be allowed in Sweden. The concept that people should be allowed to own their apartments instead of owning a part of the tenant-owner?s association is a new phenomenon in Sweden.
Att hålla tätt : Offentlig urinering och inkontinens som könad praktik
Urination is a biological need but the routines surrounding urination are culturally specific and ever changing. This makes the organization of public space an important part in deciding what actions are made possible for the people in it. This paper considers women?s public urination and the possibilities to merge the need to urinate and the construction of the female body as feminine.A number of texts that describe the construction of the female body and identity as both gendered and socially produced are analysed in relation to women?s experiences of incontinence. Incontinence as a medical diagnosis is by this becoming possible to question, and may be seen as one of several strategies used to manage both the organization of the public space and the expectations of the female body to be a docile body.The conclusion is that a woman who wants to enter public space has the following options when it comes to the need to urinate:To strive for the feminine ideal.
Automatisk viktkontroll av glascontainer
This degree project has been carried out in cooperation with Gedevelop in Helsingborg.Gedevelop has developed a camera that can calculate the weight of a liquid glass mass.Because of the density and viscosity changes in the glass, the weight information issometimes incorrect given. Glass industry is today addressing the problem by an operatorperforming a manual weighing of a few bottles which, in turn, calibrates the camera system.The project aimed to develop an automated system to control the weighing of glass bottles forglass industries. This system must be so flexible that it can be easily mounted on plants withdifferent production equipment around the world.The project includes design and construction of equipment that meets the requirementsformulated together with Gedevelop. Work has been done both in Halmstad and Helsingborgand has included both calculations and review of the theory to understand the forces thatinfluence the design of different construction parts. A prototype was produced that meets theoperating requirements for the design and can be used in testing features.
?DET ÄR JU MYCKET HUR MAN SKA VARA FÖR ATT PASSA IN SOM TONÅRING, OCH DÅ SPELAR JU NORMERNA I MEDIA ROLL FÖR HUR MAN TYCKER OM SIG SJÄLV? -En studie om Tv´s påverkan för ungdomars identitetsskapande
In this thesis we have examined if some young people's identity is influenced by television programs. We chose to illustrate this from a gender perspective and have made use of social construction theory. We did group interviews with 13 youngsters, in three groups, to find out how much insight they had in what they watch, if they believe that they are affected and how they believe that gender roles in television programs often look. Our questions are: Does young people's identity take influence of the TV program? How? Creates a social construction of gender in the television programs that young people are watching? Is there awareness among young people on what they watch and how is this in this case out? Important to emphasize is that our results are not necessarily representative of youngsters in general when we only had the opportunity to interview a few.
Elektrifiering av jordbruksmaskin : Direktkoppling till solföljare och elnät
The agricultural sector is currently highly dependent on fossil fuels, with diesel beingmost prominent. There are however both historical and modern alternatives thathave not been subject to enough evaluation to disregard them as suitable alternative.This report aims to theoretically investigate the feasibility of converting aconventional diesel driven tractor to run on electricity, delivered via a cableconnected to either the main power grid or on-site electric production, such asphotovoltaic. Delivering electricity to the machine via a cable is a method withhistorical roots in the early 20th century and in the present day mining industry.The economic and technological potential of the technique are evaluated, along withthe examination of several different motor powers, voltages, losses and constructionideas. The report finds the technique to be both possible as well as long termeconomically and environmentally beneficial. To realise this method however, somedeviations from the present methods of agricultural farming must be made,considering the more advanced driving patterns, the limited mobility and therequirement for extra driver awareness.
Fixare eller organisatör? : Byggledarens roll som intern kommunikatör
Construction companies in Sweden have for recent years seen an increase in the numbers ofwarranty complaints associated with the market of resident buildings and the cost for this hasbeen measured to over 1.2 billion SEK per year. Working with poor quality cost as a way ofcreating insight about defects within the company?s processes is a method developed and usedby the manufacturing industry for decades, but have not yet reached the construction industry.This study has been performed in collaboration with a Swedish construction company, wherethe author has been stationed at the aftersales division for residential buildings. Owing tocircumstances, this published report has been made anonymous regarding the company whowill further on be namedthe Company. The Company is aware that warranty claims producegreat costs and has requested a way of putting cost and cause to specific claims in order ofreceiving a more specific cost view and to make the reuse of knowledge more efficient.
Analys av leksaksrobot, skapande av monster
During spring 2009 a three meter tall and laughing robot was developed in collaboration between Royal Institute of Technology and Royal University College of Fine Arts. The robots function and esthetics is based on an existing toy robot called Elmo. Elmo is 30 cm tall but now the goal was to make it 1000 times bigger in order to present it on the spring exhibition of Royal University College of Fine Arts. Due to only four months of developing and building time a demand of fast determination and good planning was required. In order to make a good structure for the project it is divided into five phases: Analysis of Elmo, planning, concept development, detail construction and finally product development and testing.In the first phase valuable knowledge is obtained according to the movements and geometry of Elmo.
Anläggning av traditionellt VA-schakt : En fallstudie i logistik och byggstyrning
A growing issue in the construction industry is how production can become moreefficient by using logistical solutions. Companies can minimize the cost of a project byreducing the time to perform the work.The purpose of this report was to examine the logistics related to pipe trenches forSIAAB. The report's focus has been on solving problems and planning that wouldfacilitate the work of the project Vaksala-Lunda Etapp 3.The case study consists of interviews with SIAAB's employees and an observationwhere the progress of a traditional pipe trench has been documented using checklists.Questions to the report?s case study come from the theoretical part, which is basedon literature on construction management and logistics in general. The observationlasted five weeks and the biggest time-consuming events that affected the pipe trenchduring this time, has received most attention.
Pojkar bör och pojkar gör : Om maskulinitetsskapande i gymnasiet
This thesis aims to spread some light over the phenomena of gender construction in the upper secondary school. The background of this thesis is the gender gap in education. Girls are more successful in school and receive better grades than boys. The explanation that is given for this is that pupils are limited by far to rigid gender roles (DEJA 2010). The question is how these gender roles ? and specifically masculinity ? are constructed.
