This master thesis is an early concept development project about using plastic films and sheets as materials for shaping openings for Tetra Pak packages. It is also a technical introduction highlighting the areas of importance for the development of plastic film and sheets openings. The master thesis has been carried out as a co-operation between Chalmers University of Technology, KTH Royal Institute of Technology and Tetra Pak AB.The master thesis study presents an introduction that gives an understanding of the technical complexities and design possibilities of using thin plastic films and sheets in liquid carton openings. The knowledge is then transferred into five design concepts which points out the areas of opportunity. The technical introduction is widespread and extensive covering current packing trends, the liquid carton package and openings, thermoplastic material properties, and thin film and sheet manufacturing and shaping.

The Egyptian religion viewed the whole world as divine and inhabited by both gods and men. Concepts such as death was therefore explained through myths. The ancient society feared death but desired an eternal life. The Egyptians saw death as a physical dismemberment of the body as had happened in the myth of Osiris when death was first introduced to the world. Osiris functioned as a prototype for all men as he had overcome death by finding a new existence in the netherworld.

The town square is an important public space and is often described as the city´s living room. By creating a lively city center a sense of security is developed among the citizens which makes them wanting to use the town square regardless the time of the day. One important meeting point in Gävle is the centrally located Stortorget, sited between Drottninggatan and Nygatan. The town square went through an extensive renovation followed by both positive and negative reactions among the City´s inhabitants.  The aim with the study was to investigate the main walking paths and meeting points as a planning support to Gävle Municipality in their work with a new city plan. By studying the pedestrian movement patterns at Stortorget, Nygatan and Drottninggatan, the main walking paths and meeting points during all hours of the day was obtained.

AbstractIn November 2011 the Swedish Government announced that they were conducting an investigation to examine what impact the conversion of existing rental stock to condominiums could have on the development of the Million programme areas. The proposal of converting rental stocks to condominiums aims to help people living in these neighbourhoods to private ownership, while still allowing people who want to continue to rent their homes to do that. This thesis intends to investigate the effects of the proposed reform from a management perspective. The maintenance of the areas built during the Million Programme gets more neglected every year that passes. The majority of the housing stock is rental properties and extensive renovation of the surface layer, tribes and public spaces are essential in all Million programme areas studied. By transforming a portion of the housing stock into condominiums and by improve the living environment through renovations, these areas would be able to gets more attractive.

Den 10 mars år 2000 blev det i Sverigen tillåtet för noterade publika aktiebolag att förvärva och överlåta egna aktier. Ett starkt motiv för att tillåta återköp av aktier var enligt lagstiftarna att företagen skulle få möjlighet att dela ut vinstmedel till aktieägarna och att de skulle få en ökad flexibilitet att skapa en bättre kapitalstruktur.Återköpsfenomentet har enligt utländsk förebild snabbt blivit populärt hos svenska företagsledningar. Därför avsåg vi att studera vilken effekt aktieåterköpsprogram har på företagens aktiekurser, på kort och på lång sikt. Vi avsåg även studera vilka motiv som låg bakom återköpsprogrammen.I USA har återköpsfenomenet funnits en längre tid och ett flertal studier har genomförts. De amerikanska studierna visar att det uppstår en begränsad kursuppgång i samband med annonseringen.

The theory that concepts that are interpreted subjectively in building care creates problems in how the concepts are defined in practice within the current governing documents and guidelines for building care. This essay has studied concepts in the building maintenance literature to investigate whether there is consensus in compliance practice within the building process. In the study, 9 concepts have been investigated through conversational interviews and questionnaires answered by practitioners with extensive experience in building care processes. In the survey, an attempt is made, to measure how big or small the consensus is between practitioners who often need to collaborate within the building maintenance process. The investigation shows that existence of the concepts in building maintenance is very common in the theoretical literature examined but is almost completely absent in the craft area. Since laws, regulations, principles, and guidelines have defined concepts to support the decisions in the building maintenance process, it can be concluded that there is a lack of practice for compliance.

Projekt har blivit en allt vanligare arbetsform i dagens organisationer, men trots arbetsformens ökande popularitet inom flera olika sektorer så är det inte ovanligt att problem uppstår i samband med ett projekt. För att erhålla en ökad kontroll över ett projekt har därför sofistikerade projektstyrningsmetoder utvecklats, främst av militära myndigheter i USA. Syftet med denna uppsats var att beskriva hur en av de framtagna metoderna, EVM, kan vara ett verktyg för projektstyrning och hur metoden bör implementeras. Vi har också undersökt vilka problem som kan uppstå vid ett byte av projekstyrningsmetod. För att uppnå syftet med uppsatsen har vi genomfört en omfattande litteraturstudie samt en fallstudie på SSAB Tunnplåt i Luleå.

ITT Flygt is a world leading company that mainly manufactures submersible pumps. A problem of ITT Flygt is that product development projects rarely manage to hold the estimated project time. It shows that something unexpected occurs in projects quite often, which results in delays. The delays can both be due to an optimistic time plan of projects and risks in product development projects which are not discovered at an early stage. This added with unforeseen delays makes it difficult for ITT Flygt to estimate the duration of their projects.The goal with the Master thesis is to examine a suitable method for simulation of project time.

Due to recent legal enactments regarding carbon dioxide emissions, the car industry is facing higher demands. An effective way of reducing these emissions is to minimize the weight of the vehicle. This thesis constitutes a feasibility study on whether or not it is applicable for the car industry to utilize an inner floor structure comprising composite materials. The principal was the projectSåNätt, in which the main participant was Volvo Cars Corp. In consultation with a reference group, consisting of delegates from the industry and KTH, a specification of requirements was produced.

Several technical solutions are ready to step forward as the new generation of propellant, and this report aims to explore the possibility of commercializing fuel cell cars. The report is based on current research and data from today's technology and engineering solutions that are estimated to be commercially realized before 2020.A mapping of today?s different fuel cell options has shown that the most suitable fuel cell option is the Proton Exchange Membrane Fuel Cell, which uses hydrogen as fuel. The report is focusing on a techno-economic well-to-wheel analysis of hydrogen and the energy balance and costs in a system perspective. The basis for this analysis consists of two centralized methods of production, steam methane reforming (SMR), and alkaline water electrolysis.

This essay gives the reader an overview of the different problems and issues a landscape architect might meet, in the process of planning and realizing an eco-village. Its aim is to stimulate new ideas, based on the traditional, present and future working field of landscape architects. The essay does not claim to cover all imaginable aspects of social sustainability within an eco- village, but refers to the presented sources for further in-depth reading. Although the original focus has been on physical planning, the interviewees? words have been of big importance, and to a certain extent changed the constitution of this essay.

This thesis investigated the possibilities to resume cultivation of an old manor house built of timber and what this would mean from an energy and moisture perspective. The building in this case study is named Sofiedals mansion and was built in 1858 in Valbo 11 kilometers west of Gävle.The structure of the house was documented and used as a starting-point for carrying out calculations focused on energy and moisture aspects. With the help of a number of computer programs and a conducted air tightness test, the buildings energy consumption were calculated and compared with the current building regulations.In addition, the building was analyzed considering energy retrofitting and what it meant for moisture problems. The energy retrofitting consisted of additional insulation, decreasing the buildings permeability through air sealing; window and door replacements. When a building is equipped with natural ventilation it is difficult to know its precise performance and how an energy retrofitting affects it.

This thesis has been performed at Scania CV AB Technical Centre in Södertälje and its aim hasbeen to study the causes and effects of deformations in the interface between the rear axlehousing ADA1100 and the central gear house R780 during operation. Design changes that wouldincrease the sealing capability of the studied interface are also suggested. Finite element (FE)and CAD software have been the primary tools in this study.Finite element (FE) simulations are used in the industry to predict and develop engineeringdesigns. The main motive for FE simulations has traditionally been to identify weak spots in thedesign, regarding high tensions and large deformations.The FE model is an aggregation of submodels and interface models that represents the rear axlehousing, suspension, central gear, central gear housing, wheels, bolts and weldings, and theirinteractions. The submodels have different material properties and they are connected withcontact interface models.Boundary conditions are defined on the bushings in front of the rear axle and on the air bellowsbehind the rear axle.

Abstract This essay is written to answer the questions of why, how and against who employees in the service sector use humour, charm and flirt in the interaction with their customers. The service management research is quite extensive, but despite this the research partly misses studies around why employees tend to act in certain ways while interacting with their customers. To understand the reasons of why they act in these particular ways, we need to know which factors that can be crucial when it comes to the employees? behaviour in these situations. By knowing the underlying reasons of using a special way to communicate with customers, it is much easier to achieve a clearer overview of the subject.
