An energy study has been performed on two blocks in an area called Gävle Strand. The buildings are owned by a tenant-owner?s association called brf Carolina and were built by the company Skanska 2008. The builder as well as brf Carolina are pussled by the fact that electricity use is higher than expected while heating is less. Skanska is also very interested in finding out how much heat recovery from stale exhaust air through a geo-thermal heat pump is contributing to the general heating requirement and energy balance in four out of the ten buildings located on the properties.To find possible answers to the higher electricity use a literature survey on user behaviour was conducted.

Many research reports mention the fact that a huge number of all system development projects never reach a successful ending; with other words never fulfil formulated goals. By identifying and forming success factors (and in some aspect risk factors) that the project manager in practice can use, this study may be seen as a step in the direction towards minimising the high number of failed system development projects. The purpose of this research report is to investigate how a system development project, where the development process is based on a specific development or process model (in this case the Waterfall model), can and should be driven. I aim to clarify what is demanded of a project leader for the specific development process and give an account for which eventual leadership qualities that can be well suited for given situation in relation to the need for technical competence. Among other things the project manager should inspire confidence, drive, be a decision maker, engage and own some form of basic knowledge in the field of system development.

HemoCue AB is a multinational corporation targeted on manufacturing point-of-care analysisinstruments for medical treatment. Their main product, the DM 201, is outdated and has bigissues gaining new market shares. For example, no medical treatment center in Sweden usesDM 201 frequently. The project of developing a new instrument to replace it was assignedtwo students at the development engineering program at Halmstad University. The projectalso included integration of the new platform for DM 202 to HemoCue AB:s remainingproducts.The project began by defining the different technical areas concerned.

The primary focus of this Master thesis is to study how industrial house building can be implemented during production of rental flats under the terms of public procurement. In order to determine a suitable working process as well as presenting a possible architectonic result of the process, a case study is carried through.A housing projekt is designed on a site i Malmö, where the commisioner is MKB Fastighets AB and the contractor is NCC Komponent with the industrial building system NCC Komplett. The focus of the design is to accomplish high quality apartments to a resonable price, as well as solving the overall scheme for the site.The housing projekt, Kv. Flaggskepparen, built on the consept of a single house model, used to handle the entire site, shows that the building system is well suited to accomodate the commisioners demands.In order to reach the best possible architectonic result with the building system, cooperation initiatded in an early stage of the process is neccesary.A model is proposed to handle the situation under the terms of public procurement. The model suggest that the geometrical design is mainly carried out after inquiry and that architectonic qualities should mainly be defined in a non geometrial way for inquiry..

This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.

In today?s society computers are getting a much more important role. To get a computer to work as intended it has to be programmed. A computer program is written with programming languages. There is an abundance of programming languages available today and there are many differences and similarities between them. The different languages have their advantages and their disadvantages where some of them are intended for fast performance, some to be cheap on memory usage, and some are developed to be easy to program on. In our thesis we have chosen to compare four of todays most common languages, C, C++, Java and Python.

The company is currently in a stage of improvement and has therefore taken the help of students at School of Engineering, Jonkoping University. The current production is batch, production layout is fixed. A bottleneck is created after the first station which leads to large efficiency loss.  The meaning of this report was to provide a layout suggestion with balanced workstations to a new production line. The conditions were that the production line would be one-way, driven by customers order and meet a demand of 40 products per week.

The Swedish industrial society has left several areas with contaminated soil and water which today is of danger for the environment and human health. One of these areas with contaminated soil and water is the region where the former Glava glassworks operated during 1859 to 1939. The main object in this study has been to study the responsibility for the contaminations according to the Environmental Code. The method used is a qualitative content analysis of relevant literature to answer the following questions:What types of contaminations can be found in the area of Glava glasswork and what health issues can these cause?What kind of activity has been conducted in the area that have caused the contaminations in soil and water?According to law, what are the responsibilities for the contaminations in soil and water at Glava glassworks?The contamination in the region has been confirmed to originate from the glasswork due to the environmental engineering survey made in the area in 2009.

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.

In Sweden the most common type of road traffic accidents involving passenger cars are single accidents (where only one vehicle is involved). The aim of this thesis is to analyse how these accidents occur, and present recommendations on how to reduce the number of deaths. Data has been collected from the Swedish Transport Administration?s in-depth studies of fatal accidents. Road traffic accidents with fatal outcome that happened on public roads during the years 2007 to 2009 have been studied.

Bakgrund och problem: Revisionsplikten avskaffades 1 november 2010 vilket betyder att mindre aktiebolag som uppfyller vissa kriterier inte längre behöver anställa en revisor. Enligt uppgifter från Bolagsverket är det en stor majoritet av de äldre aktiebolagen som väljer att behålla sin revisor medan det hos de nyregistrerade aktiebolagen är vanligare att inte ha en revisor.Syfte: Syftet med uppsatsen är att undersöka vilka faktorer som är avgörande för mindre aktiebolag i valet att ha en revisor. Vi ska även undersöka vilka fördelar och nackdelar de mindre aktiebolagen ser med revision och om synen varierar beroende på om det är ett bolag som registrerades innan eller efter avskaffandet av revisionsplikten.Metod: I studien används en kvalitativ metod i form av intervjuer. Personliga intervjuer genomfördes med sju olika mindre aktiebolag.Resultat och slutsats: Samtliga bolag är allmänt positiva till avskaffandet av revisionsplikten och menar att majoriteten av mindre aktiebolag inte har ett behov av en revisor. Majoriteten av bolagen anser att revision är en bra kvalitetsgaranti gentemot ett bolags intressenter.

Syftet med arbetet var att göra ett koncept av en robotcell som kunden skulle presentera för den Europeiska koncernen. Med konceptet som grund skulle koncernen ta ett beslut om de ville investera i en robotcell för att kunna utöka sin produktflora. Ett krav för att tillverka robotcellen var att göra den så flexibel som möjligt eftersom kunden ville producera olika varianter av samma produkt. En simulering i robotstudio blev en grund för en film som visade hur materialet tillverkades i robotcellen och även vilka materialprocesser som ingick vid förädlingen av materialet.Varje koncept började med en ritning i sketch för få en enkel överblick av hur layouten kunde se ut. Därefter bestämdes det om layouten var realistisk och om det skulle bli någon 3D modell av layouten.

AbstractArtists ? the invisible assets; a qualitative study about the view on music rights and artist brands as intangible assets within music companies.This paper is a study of what view representatives from Swedish music companies have on activating music rights and artist brands as intangible assets. Throughout the paper, a discussion is held regarding what the representatives think about activating these intangible assets. From this, we have identified and analyzed possible pros and cons to such activation.Our interest to this question was brought to us when we realized that most music companies in Sweden have intangible assets without activating them. This is, even though these are their main source of income.

This thesis looks at two sides of the same coin: how to support the production and future development at a specialist medical technology department at Danderyd Hospital. The two sides are; a pilot study of a product management system (PDM) and an interview based study on the characteristics of the silent knowledge of the technicians. The department (National respiratory centre, NRC) is facing retirement of several key employees.The technical study shows that the success of an implementation is largely dependent on the users? prior knowledge and use of a 3D Computer aided design system (CAD).The system itself is shown to fulfill the Lifecycle requirement of tracking the products (mostly tracheostomy tubes) but without a CAD centered workflow, some substantial education and preferably some new recruits, an implementation of the PDM system will fail. The author recommends development of the current ?low-tech? system of MS Excel and Access rather than redistribute the dependency from technician towards a complex, commercial software and its vendor.The analysis of the technicians? silent knowledge with the newly developed method, epithet for silent knowledge (ETK), shows that the longer employment time:the more differentiated technicians become in describing their work,practical knowledge are regarded higher andthe social and collective problem solving factors of the work becomes more important.Typically, it is shown that a new employee should preferably enjoy problem solving, being pragmatic and social as well as having some prior education or work experience in a CAD and/or a PDM system..

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.
