This thesis has treated a three-axis robot which task is to serve a larger test machine tomove the modules to be tested, from the storage to the test site. The robot is composed ofthree linear actuators; two standard components of ball screw type and a custom-builtactuator of trapezoidal type. The work has mainly focused on the custom-built device to seeif it could be replaced with a standard component. Part of the work has been to look into thepicking tool and to see if there are any possibilities to improve its function.The report presents two different proposals which I decided to call Robot 1 and Robot 2 andthey aim to address the problems arising in the purpose-built linear unit and the X-axislinearity problems. Robot 1 focuses on eliminating the problems that arise around therobot's X-axis, with such simple means as possible and without making excessive materialchanges.

This thesis work is a 30hp D-level assignment in design as a co-operation between MälardalenUniversity and Scania CV AB in Södertälje. The purpose was to develope a close fitted catwalk.The market has seen an increasing value for these types of applications and have the ambition to keep up with the rest of the competitors. The catwalks of todays standards shall be estetical attractive, have a non slippery surface and be costefficient.While working with this project I have spent a lot of time with the concept proposals and with the evaluation of the concepts, resulting in a final CAD model and a approximation of the cost estimate. The new catwalk fulfils all the new recommendations and rules as sharp edges, ADR, the height of the stepup and a non slippery surface with built in drainage..

I dagsläget finns en stor mängd byggnader i Sverige där fasaden består av puts direkt anliggande mot antingen lättbetong eller tegel. Dessa fasader kan skapa problem för brukaren p.g.a. fukttransport via putsen direkt in i konstruktionen. Problemen som kan uppstå som följd av dessa konstruktioner är inte bara estetiska utan kan även påverka inomhusmiljön. Syftet med detta arbete var att undersöka om det gick att med ny teknik visa de resultat som framkommit från erfarenheter från praktiskt arbete samt undersöka hur en renovering påverkar de fasader som består av puts direkt mot lättbetong eller tegel.

This study titled School Model of Norrberga- a New Model of School. Some opinions that six pupils in the sixth grade have of their school is an explorative study. The purpose of this study is to some extent explain the ideas behind this quite spectacular model of school and the intentions of the City Council of Norrberga as they decided that all the schools that were to be renovated or built in the town of Norrberga had to follow a specific script.   As I first visited The Moonlight School I was puzzled. How do the teachers work it out? But, above all: Do the pupils work it out? What do they think about their school? When I was to write my final essay I wanted to try to sort this school out in more scientific terms. There is a nice, warm atmosphere at the school and the pupils make good results.

Tile covered bathrooms require a wellexecuted waterproofing in order toprotect the underlying construction frommoisture. Länsforsakringar Uppsala paysannually out millions in insurance fordamages related to poor waterproofedbathrooms. In recent years, SP (SwedishNational Testing and Research Institute)investigated and researchedwaterproofing products, resulting ingreater shortcomings of product defectsthan expected.This report raises the problemsconcerning waterproofing and discusseswhy they occur. By studying productinstructions and insurance cases anddamage reports provided byLänsforsakringar, the most commonproblems concerning bathroomwaterproofing where concluded. Animportant part of the report was tofind out the actual cause to whywaterproofing damages occur.The results of the survey indicate thata common cause of water damage usuallyis related to poor productinstallations.

Today the human being see energy as a matter of course but the resources that is used for extract energy is today not enough for the world demand. Of all the energy that is used in Sweden today approximately 40 % goes to the building stock. This number will most likely increase if not necessary actions will be made on the already existing building stock since new houses constantly are built which will be added up on the already existing energy supply. This takes cause of action on the already existing building stocks, to fulfill the demands of the future use of energy that has been set by the authority. At the same time the thermal conditions cannot be influenced by the necessary changes that must be made.

Partnering is a new and exciting way of cooperation in the Swedish construction industry. In countries like Denmark and the United Kingdom the concept has been developed during a number of years while the Swedish construction industry has been more reluctant.Partnering is seen by many as the solution to the problems that often occur in design and build contracts. Many others believe that it is a way for the big entrepreneurs to gain unfair advantage. Never the less the concept is fast getting more and more appreciation, especially in the region of Karlstad where many new buildings are built that way.We have focused on the new development of Carlstad Conference Center (CCC) which is currently built with a partnering concept. The main method that have been used in this thesis are interviews with personnel on different positions in the project.

The municipalities of Sweden have a great responsibility when it comes to adapt the physical planning to a more sustainable development. The development of the society depends upon the growth of new communities and other public services, but to build new communities in a long-term sustainable manner you need good methods and guidance. This study presents four sustainability certification scheme intended to improve and adapt the planning, implementation and performance of new communities and infrastructure project to more sustainable methods based on economic, ecological and social sustainability. These systems are the latest versions of environmental classifications and similar rating schemes, but with a broader focus since they also include the social aspect of sustainability.This study aims to investigate what role sustainability certification schemes can play in local planning for sustainable development. The study compares the certification systems criteria to the tools and goals that the Swedish municipalities have been provided with, to lead efforts towards a more sustainable society.

This master thesis has been performed at Solvina in Gothenburg for Skellefteå Kraftand Vattenfall Eldistribution. The aim of it is to investigate the consequences of theinstallation of a wind power plant on the mountain Uljabuouda in the vicinity ofArjeplog. Especially the impacts on voltage and transient stability are examined.Furthermore, the amount of extra strain on the voltage regulation equipment and theneeds for increased regulation capabilities are looked into.The wind power plant is planned to be built by Skellefteå Kraft and connected to a130 kV grid owned by Vattenfall Eldistribution. The work comprehends the followingmain parts:- Theoretical studies aimed at wind turbines and power system stability issues.- Modelling of the type of wind turbines assumed to be built on Uljabuouda.- Simulations of different operation cases and analysis of the simulation results.The results from the simulations show that, as far as voltage stability and extraworkload on tap-changers are concerned, the wind power plant does not, in anysignificant manner, worsen the present conditions. The problem of overloading theline between Arvidsjaur and Vargfors is also minor.

The reduction of coarse, dead wood is considered to be the biggest threat to flora and faunain boreal forests. Extensive harvest of logging residues would increase this reduction evenmore. However, the role of dead wood created at final felling for boreal, epixylic species isstill largely unclear. It is therefore of interest to examine whether epixylic species inhabit thedead wood in young, boreal stands, especially species considered to be confined to forests inlate successional stages.The aim of this study was to investigate whether forest-interior species in fact can inhabitearly-successional forests arisen after logging. The study was conducted in young standsbordering dead wood rich woodland key habitats.

The focus of this two year master?s thesis in Library- and Information science is the study of two Swedish Public Library buildings with the examples Lomma and Halmstad. The main goal and purpose of the thesis is to try to uncover which views and values of the public library are expressed in the examined libraries; and to what extent these views manifests are shown in its architecture.The theoretical framework is based on Raymond Williams?s cultural concepts of effective, dominant culture and the two extremities of this culture, called residual and emergent cultures. A second aspect is Yi-Fu Tuans concepts of Space and Place.

I was assigned to the thesis as part of a project GMA AB (Ground Machinery Applications AB) is running. The project aims to develop a new method for injection of drilled holes in rock walls. Currently, the injections usually involve cement but the basic idea of the project is to replace cement with a supplement called Silica sol.Silica sol is known as a gelling liquid. The gel time is controlled by a mixing of saline. Depending on the amount saline that gets mixed in, the gel time varies.

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).

The ongoing change that characterizes the landscape as a result of the development of the society as a wholeis the basis for this thesis. Even though the Scanian landscape still is dominated by arable land, other valuessuch as biological diversity, cultural heritage and economical aspects, has all been ascribed the landscape asmore and more important factors and in some respects, compete with the farming industry about the right tothe landscape. Our demand of more and more space, will of course also affect the landscape. Huge amountof land are used to build external malls and single-family houses, which gives rise to an increasing need foran extended transport system that also is land consuming.It all comes down to: how the municipalities deal with non built areas - the green structure. Do themunicipalities have separate programs describing their vision and objectives concerning the green structure?Literature studies, an inventory made of the municipality programs in the west and south west of Scaniaand interviews with employees at the municipalities clarifies the use of the green structure concept, both intheory and in practice.The green structure concept seems to be derived from the environmental debate.

Många byggnader är idag fuktskadade. Fuktskador uppstår på så väl nya som gamla byggnader. Idag provtrycker man hus för att få ett värde på dess täthet, men många hus som klarar täthetskraven drabbas ändå av fuktskador. Detta beror på att otätheterna är lokala på en eller flera delar av klimatskalet bortsett från otätheter vid anslutningar.  En studie har gjorts på två väggtyper; en standardvägg och en passivhusvägg.
