Betalningsmodeller för det svenska elnätet : Vilken modell kommer att fungera bäst för konsumenten?
Recent years there has been discussed how the critical situation in the housing market threatens the Stockholm region's growth. The thesis objective is to examine whether there is a scientific link between the lack of housing supply and growth. The thesis also intends to identify solutions for increased housing construction, for instance by examining the conditions for a greater regional perspective and influence on the region's housing supply. The thesis empirical study is based on semi-structured interviews with representatives from the Government, municipalities and the housing industry.In Sweden, research on the relationship between housing shortages and growth has not been conducted to that extent it can be said to exist scientific evidence regarding the growth threat. However, in Britain and the U.S, empirical studies show that a lack of housing supply has hindered growth through negative impact on countries' gross domestic product.
Ronningsgift
This thesis examines the sheep shed called Ronningsgift, and its historical functions and geographical
location. The study aims to make a comprehensive gathering of the existing knowledge and to shed
light on new theories about the history of Ronningsgift. This is done through desk research including
literature and archive search, as well as an investigation and description of the construction and
materials, and an interview. Further, I got the opportunity to take part of the results of two C14
samples from Ronningsgift.
The literature and archive search shows that the most common theory of the historical function is as a
guest house (g?ststuga/h?gstuga) or more traditionally called, Malst?ue/Malsteuvu.
Processförbättring för tillverkandet av specialbalk
Examensarbetet genomfördes åt företaget Corus Byggsystem AB. Ett företag placerat i Halmstad som tillverkar profilplåt och lättbalk till tak och fasader. Företaget erbjuder även god rådgivning och skapar optimala lösningar för kunden.I företagets produktion finns det en maskin som pressar specialbalkar. Denna arbetsplats är varken produktionseffektiv eller ergonomiskt riktig då materialet och balkarna lyftes manuellt, i vissa fall även över huvudet. På tunga arbetsplatser är det oerhört viktigt att se över ergonomin, både för att förbättra säkerheten och för att öka produktionsvolymen.
Effektivisering av pulverlackeringslinje med inriktning på fixturer
The project has been oriented for development of fixtures to ateljé Lyktan to
provide a more efficiency line. In the year 2012 the company invested in a new
coating booth, which leads to opportunities to upgrading the fixtures and also
new design. The request is to minimize the area for storage of fixtures, and
therefore should fixtures be designed to apply as many articles as possible
The priority of products that fixtures have development to has been products
that are most frequently coated and new products that don?t have any fixtures.
The product families that the project has been having focus on is TIME and
FOVEA with RONDO.
In the developing of fixtures have ideas been discussed with the staff, and
instructions were made about how you are suppose to hang up the different
products.

The goal is to buildthe car that consumes the least fuel during a race. KTH participated for the first time in 2006.The engine for this competition, DoubleTwo, has been developed within the school. Theprinciple is a two stroke counter piston HCCI engine with variable compression ratio. HCCIstands for homogenous charge compression ignition.
Utvärdering av den biologiska reningen av processavloppsvattnet vid GE Healthcare i Uppsala
GE Healthcare operates in Uppsala (Sweden) and develops systems, equipments and medium to purify medical substances. Discussions with the local authority concerning planed far-reaching changes and upgrades of the biological process techniques for sewage management, aroused the question about revising the terms of permit for the activity. Therefore it seemed necessary to evaluate a newly installed biological process technique, which is the background of this thesis. The evaluated biological treatment process was built in 2003 and consists of a biological reactor filled with moving bed carriers with a high surface area for biological growth. At the time of the project the biological wastewater treatment plant consisted of a flow equalization facility and two following parallel biological processes; a biological reactor with moving bed carriers and a tower trickling filter.The aim of this thesis was to survey the function of the biological reactor with respect to the reduction of organic matter.
Erfarenhetsåterföring av konstruktionslösningar Optimal utformning av ett detaljbibliotek med standardiserade konstruktionslösningar
This thesis has been carried out at the Building and Civil Engineering Programme at Chalmers University of Technology in cooperation with NCC Technology. The study aims to investigate the optimal design of a library of standardized structural solutions for in-house multi-family buildings and what benefits it brings. Today NCC use technology platforms to improve efficiency and simplify the construction process. The platforms provide the constructors guidelines on how construction details should look like, but the details are not complete. NCC Technology started in the spring of 2013 a project to investigate what benefits there are to create a library of standardized structural solutions for the constructors, with more detailed solutions than in the platforms.
En såndär som alltid gör fel : En litteraturstudie om upplevelser och hantering av stämpling av individer med en ADHD-diagnos.
This study intends to investigate the experiences of labeling on people with a ADHD diagnos and how individuals with an ADHD diagnosis handles labeling. In today's society normality is is something that is pursued and the individuals that do not meet the normality are perceived as deviant. The study is conducted with a qualitative method and is based on three autobiographies where individuals with an ADHD diagnosis writes about their life. The study deals with postmodern constructivism which is explaining that the normalization and deviances are constantly changing, both depending on time and context. The results and analysis of this study are presented under three main headings that are related to the study's research questions.
LÖNSAMHETSKALKYL AV FUKTSÄKERHETSANSVARIG VID RENOVERING : En fallstudie av ett projekt där ByggaF-metoden har använts
The so called ?ByggaF-method? is a relatively new Swedish method to stop moisture from being built into a building. The method should prevent damages on buildings as a result of mould growth and moisture. The purpose of the method is to include moisture control in the entire constructionprocess, from the projecting phase and all the way to the management phase. Up until now, there is no proof if the method is profitable or not and no studies have been made on the topic.
Flexibel isolering av fönster för att minska energiförluster
The first part of this essay is about a single-family house that we have planned and projected. Thesecond part is a deeper study in ways to further insulate windows when they are not in use.In the first part the building?s design and its most important construction elements are described.The planning of all major installations (heating, domestic water, ventilation, sanitation, electricity)are reported so that one can in principle start construction of the house. In addition there arecalculations done on the building?s energy management.The result is a two stored house angled toward the south.
Konstruktionen av Sverige och en svensk identitet : Diskursanalys av två läromedel i svenska som andraspråk
This essay is written in order to expose the construction of collective identity in textbooks for Swedish as a second language. To help visualize the process that shapes and categorize sub-jects based on a relational identity formation I assume mostly from Ernesto Laclau and Chan-tal Mouffe's discourse analysis theory frame. The paper called it as discourse theory. There are two textbooks in Swedish as a second language to be studied. Based on the textual materi-al found in the textbooks I perform a discourse analysis involving mainly focus on relational identity construction.
Optimering av blekeriet i CTMP-linjen vid Rottneros Bruk
At Rottneros pulp mill mechanical pulp is bleached with hydrogen peroxide. The changes of bleaching chemicals that are used for different grades are taken from bleaching tables; however these tables are old and need to be updated. The purpose of this thesis was to be the basis of new documentation.In this thesis three pulps where studied with the aim to find the optimal bleaching chemical changes (total NaOH/VP-quote) for each pulp. The pulps were taken from the filter before the bleaching tower and the pulps were bleached in the lab. The most important pulp property in this study was the brightness and how that was influenced by the chemical dosages.
Kärleken dekonstruerad : En analys av Hjalmar Söderbergs Den allvarsamma leken
Den allvarsamma leken (1912) by Hjalmar Söderberg has been regarded as one of the greatest love novels of Swedish literature. The story about Arvid Stjärnblom and Lydia Stille and their extramarital love is marked by timeless universality.In this essay, I will examine this notion of love as a prediscursive value, by means pro¬vided by foremost poststructuralist theory. With Derrida?s conception of deconstruction, the analysis will reveal the constructedness of the true love in Söderbergs novel. Examinating typi¬cal logocentric binarisms the essay will show that the notion of true love is constituting a term in an oppositional relation with, in this specific case, the marriage sanctioned by society.
Att vara muslim i Sverige: En studie av svenska muslimers identitetskonstruktion i ljuset av globalisering och (post)koloniala narrativ
This study concerns ways in which Muslims in Sweden construct their identities. The theoretical approach of the study is based on the assumption that people construct their identities through narratives. Circumstances such as time, place, and relationships affect how narratives are told and therefore how we perceive ourselves and the world around us.In the wake of 11th of September 2001, the old colonial narrative of ?the West vs. the East? has become powerful, and makes many question the possibility of successfully integrating Muslims immigrants in Western countries.
Utveckling av styrning till solföljande MaReCo-hybrid i Hammarby Sjöstad
Turning solar collectors, heliostats, is certainly not a new idea but has been explored for at least two decades. Projects on this subject have resulted in more or less realistic constructions, in a commercial point of view. Far too often the technical goals have had higher priority than the economical, which has resulted in a few constructions having the ability to compete with conventional, fix solar collectors. The economical issues have been given high priority in this project, without decreasing the demands on reliability. The system has been given the following mechanical and electronical properties: One-axis movement, fix heat carrying fluid system, microcomputer controlled movement and automatic protection from overheating.
