This thesis has been done at the powder department (GH) at AB Sandvik Coromant in Gimo. With a rheometer measurements has been made on raw materials and powder blends. The focus of this report has been to find correlations between raw material powders and press data, comparisons have also been made between raw materials and powder blends.The rheometer can show information of how a powder act in flow conditions, together with air and with pressure. Analyses has been done comparing the rheometer data with press parameters (for example: rejected orders, weight variations and the compaction pressure) with the goal to find correlations between the powders flow properties and the powders compaction in production.The measurements and analyses have been showing that the powder flow properties depends on the powders composition and that properties like flow rate, aeration and permeability varies between powder blends and batches of the same powder sort. It seems to exist a correlation between the pressure force and the flow rate of a raw material.

Examensarbetet redogör för byggproduktionsplanering med en fördjupning inom tidsplaneringsmetoder- och verktyg, vilka kan användas som hjälpmedel inom området.  Inom fördjupningen gjordes två praktiska försök och intervjuer genomfördes för att få en verklig bild av hur planeringen fungerar, samt för att få feedback på försöken.  Arbetet resulterade i slutsatsen att olika planeringsmetoder bör användas i olika skeden av byggproduktionsplaneringen, samt att de olika planeringsmetoderna är till olika nytta för de varierande arbetsrollerna i en byggorganisation.  Man kan med fördel använda sig av en kombination av planeringsmetoderna, CPM, LOB och den relativt okända ?Kontinuitetsmetoden? när man planerar och styr sin byggproduktion.

AbstractThe aim of this essay is to bring understanding to one of the problems theinternationally adopted in Sweden might face, the identity dilemma. In order to do so, a theory of identity construction, Constructionism, is used. This theory says that the construction of identities is a constantly continuing process, influenced, not only by our own perception of ourselves, but also by how we are viewed and treated by otherpeople.Given this theoretic starting point, an examination of the adoptees? everydayencounters in the Swedish society is made, using an autobiography, a biography, a collection of interviews, and newspaper articles. The result shows that the internationally adopted, although they are Swedish both by mind and by law, experience that they have been, and sometimes still are, confronted with strong attitudes such as racism, prejudice and stereotypes.Furthermore, those who experience the identity dilemma often refer to how they are perceived by ?the others?, or to what the encounters with ? the real? Swedes have been like.

The essay presents a qualitative study, which intends to investigate how the identityconstruction of the second generation of young people with Kurdish origin has been formedconsidering the complexity of living between two or more different cultures as well theinfluence of family norms and values. The theoretical basis lies inthe identity construction and ethnic identity in which we have tried toexpress and illustrate this complexity. Previous research we have assumed includes affiliation,and a third identity, where we have used a number of researchers studies to elucidatethis topic. In order to facilitate the study, ten in-depth interviews with Kurdish youths aged18-25 years have been applied. The common factor for these respondents is that they all cameto Sweden at a young age.

Since the early 1940s in Sweden, subsidies have been a recurring feature in housing politics.Throughout history, these have been used as a management measure to control theconstruction of housing and to promote the Swedish welfare state. The political parties aretoday disagreeing on how much responsibility the state should carry for citizens housing. Tosolve the conflict, the dwelling has to be defined. Is the dwelling to be considered a socialright, like education and healthcare or is the dwelling to be considered a product for the freemarket, driven by supply and demand?The positive population growth in Stockholm has lead to an increased demand for dwellings.The supply of dwellings has not been growing at the same rate, which has implied higherhousing prices and longer wait for rented apartments.

In the automatic manual transmission system, Opticruise, the choice of gear is based on several parameters such as road incline, driving resistance and vehicle mass. Many different mass estimations are made during driving. A final vehicle mass is then used to determine the current gear. Construction vehicles are often not equipped with air suspension and can therefore not estimate the vehicle mass when standing still. If that sort of vehicle is reloaded while standing still an incorrect mass estimation will be used and as an effect of that also a wrong gear.

This thesis aims to develop proposals and models for a modular electronics construction to a future D250S Dual battery charger. The aim also includes investigation of possibilities to use some of Texas Instruments C2000 microprocessors. The reason for this is that CTEK SWEDEN AB wants to renew the present D250S Dual battery charger and lower the manufacturing costs. The thesis work has involved gathering theoretical facts for the development of a design on the modular electronic construction, the choice on which microprocessor to use, the choice of electronic components and facts about peripheral equipment to the D250S Dual. With the theoretical there has been developed different solutions to the proposed hardware and software solutions with comparisons in aspects of positive and negative.

The construction business is one of the most accident prone businesses in Sweden. In order to make it safer it?s vital that all employees of a company report all accidents and incidents that occur. This report intends through qualitative interviews, to analyze the knowledge and attitude towards incident reporting among the employees of the Swedish construction contractor JM.The goal of the thesis work is to hopefully contribute to an increase of employees? awareness on those issues.

The background for this degree thesis is a need to replace the existing seal used to protect equipment containing secret or sensitive equipment used by Swedish Defence. The target design should satisfy both the need for tamper evidence and reduce Life Cycle Cost. In developing a new design for a seal, additional benefits such as improved logistics support and indication of attack methods such as heat and solvents have been considered.The lack of guiding principles for end users of seals became evident during the interviews. Major concerns for the future are education of users, information about actions if a seal is broken and user liability.The design work was divided into several phases. A feasibility study was performed including investigation of theory of labels, materials and possible technologies.

Background: The most energy efficient houses today are so called passive houses. These houses achieve high energy-efficiency partly by having well insulated walls. U-value describes the amount of heat transfered through a building element, the more insulation, the smaller U-value. A typical passive house wall have a U-value of 0.10 W/m2,°C. The passive houses are primarily made as small family houses and not as a block of apartments.

Construction of an autonomous wind station was a project with the goal of creating a product that could collect wind data from a sensor and then transfer this data to a server wirelessly over the GSM network. The device would be powered by batteries and solar cells and function fully without requiring external power supply. This required that a small computer was constructed and programmed to store and send data at predetermined cycle times and programming of a server that received the sent data. The project also required optimization of power consumption and dimensioning of solar cells and batteries based on this. The construction of this station demanded research both for the selection of hardware and programming software. The computer was based on a microcontroller and a GSM module that sent the data over the 2G network.

A current conveyor is an active building block that can be used to implement most active and passive components. It differs from the operation amplifier in that it uses current instead of voltage. The current conveyor also has significantly higher voltage gain over a broader frequency range. To simplify the construction of analogue circuits and increase the construction efficiency it is desirable to use a top-down methodology. This means that the whole system is partitioned into a hierarchy of subsystems.

Organic material used for biogas production can also undergo other treatments. The emissions and impact from the different treatments are evaluated in this environmental assessment, with a focus on energy and climate. The materials included in the study are organic household waste, slaughterhouse waste and liquid manure. Other than biogas production, the possible treatments for organic household waste and slaughterhouse waste are incineration and composting, and for liquid manure storing and spreading. The analysis is based on data and information from current and relevant literature, and relates to the conditions in the Swedish energy system.

How do we match our education with the needs of the construction line of business and the requirementsof the Swedish National Agency for education? Is there something that we have to change?In this study I have asked our former students about their opinion of our education and I have also asked them to give me their view on what a good teacher is like. I have been able to benefit a lot from their answers in my efforts to be that good teacher. This survey took place at Facebook.The answers showed that we carry on a piece of solid workmanship. But you can always improve, try harder.
