As a result of increased energy prices more and more energy-efficient homes are coveted. An energy-efficient alternative is passive houses, which is characterized by an extremely well insulated building envelope that recovers the heat without the use of radiators or under floor heating. But a passive house requires a higher investment cost than a conventional building project, since it will require more construction materials, training of construction workers, greater land area, and long construction period. But the lower operating cost expects to pay back the higher cost of investment. We therefore question how profitable a passive house is in relation to houses built according to modern conventional building techniques.The aim of our study is to investigate the viability of passive houses compared to convent­ional houses.

This report describes the construction of a climate-cabinet for testing of HV-cards (High Voltage) produced at VG Scienta. The main part of the report describes all the different components of the cabinet. The most important parts are a PID regulator from Eurotherm model 2408, a solid state contactor (SSC), a thermocouple, a finned resistor from DBK and different fans. The report even includes the connection between components by cable wiring, isolation, grounding, fuses and shaping of metal goods.As the cabinet also communicates with a computer, the report includes the solution of the data communication using the software iTools from Eurotherm. The communication part includes information about a converter that converts EIA422 to USB.The cabinet was produced at a company, called VG Scienta, in Uppsala during the spring 2010.

As energy prices skyrocket and the environmental issues become more frequently debated, interest in energy-efficient buildings has increased sharply in the past decade. Because of this, the interest to achieve high air tightness in building envelopes have once again awakened, due to a good air tightness contributes to lower energy consumption in several ways and to a healthier indoor environment.As the regulations for energy consumption and controls of achieved air tightness has tightened considerably in recent years, the work regarding sheets for air tightness changed significantly for construction contractors. This thesis includes a study that aims to detect what kind of manuals, recommendations or instructions contractors working according, and how a number of randomly selected construction companies in Halland, Sweden, are dealing with the matter of high air tightness of the building envelopes. The study also includes a knowledge inventory of supervisors, site managers and skilled workers, and what their opinions and attitudes are like towards work regarding the sheets of air tightness. The results have been compared with a similar survey dated to 2004, conducted by the SP Technical Research Institute of Sweden in collaboration with Chalmers University of Technology.

The task was to deliver a solution that could be implemented in today?s production of the FH truck. To make the project successful it was most important that the end result had a high maturity level. For that reason an analysis of ergonomic, laws and regulations, and possible materials where conducted. To show that this project is profitable and can be realized a ruff cost estimated of material and tools is added to the research.

Wooden joist slabs is a common type of floor in residential buildings. Higher demand and production of residential buildings increases the possibilities of profiting by optimizing the system of joists in a variety of areas. Spring and deflection is something most people can relate to since it?s not that uncommon to hear furniture rattle when you walk over a wooden floor. To remove the presence of those kinds of vibrations the system of joists have to be made stiffer than the standard joist construction that is used in today?s constructions.

The idea to develop  a platform for a PID-controller came from the need to control the temperature in  an espresso machine in a more exact way than a thermostat could perform. In discussions with Syntronic AB the idea developed into PID-control for industrial use. Syntronic AB suggested that the platform should be based on a commercially available processor module to shorten the development time. The suggestion included the use of the microcomputer Raspberry Pi, which supports USB, HDMI, memory card and Ethernet.The work began with establishing a schedule for the 10 weeks of the projects duration, and after that a system specification listing all functions, implementation and limitations was made. When the foundation of the system specification was done, a preliminary system design took shape.Because of the Raspberry Pi´s lack of Analog-to-Digital converter, a circuit board containing Wheatstone bridges, differential amplifiers and a two channel Analog-to-Digital converter was fabricated.

Bakgrund: Enligt en underso?kning som Stockholms handelskammare genomfo?rt tillsammans med Infotorg sa? blir internet och de sociala medierna en allt viktigare ka?lla till information fo?r arbetsgivare. I studien visar det sig av 40 procent av alla rekryterare kontrollerar kandidater via Facebook. Detta va?ckte fra?gor hos mig, som jag valde att ga? vidare med i denna kandidatuppsats.Syfte: Uppsatsens syfte a?r att underso?ka varfo?r, och pa? vilket sa?tt, arbetsgivare anva?nder sig av internet och de sociala medierna na?r de rekryterar ny personal.

Denna studie ger ökad kunskap om hur en digital artefakt inom sociala medier skulle kunna uppmuntra till äkthet, som en motpol till profilering för att skapa en balans mellan profilering och äkthet. Studien barhandlar området ?hur och varför användare presenterar sig och för sig på ett visst vis i sociala medier?. Detta förstås och diskuteras med hjälp av de två ändpunkterna äkthet och profilering. Studien berör även designerns roll i detta sammanhang.Studien undersöker området genom en litteraturstudie, samt en egen kvalitativ studie i form av semistrukturerade gruppintervjuer.

Teckning är ett arbetsområde som har hängt med från den allra tidigaste bildundervisningen, där den ännu utgör en grundbult i en alltmer svårdefinierad sammansättning. På förtjänstfulla sätt kan man idag kombinera enkla material med modern teknologi, t ex för att skapa uttryck, lösa uppgifter eller underlätta estetisk kommunikation..

This thesis aims to illustrate how environmental impact can be reduced, through the use of lean concrete. It also illustrates how environmental data can be applied to a house through implementation with BIM. In this study a unique concrete structure developed by Swedish Cement and Concrete Research Institute is assessed for environmental impact, by calculating the carbon dioxide equivalents using LCA methodology. The construction is a sandwich element where the concrete is made ??up of three layers.

This study aims to explore how a gardening project with elderly living in Djuröhemmet, a nursing home outside Stockholm, affected them regarding psychological well-being and their experience of participation during the planning and construction of the memory garden. The gardening project is new in its kind by allowing the residents to influence the design of the garden by sharing the project leader their gardening memories from previous parts of their life and by wishing for specific plants and items.  The method being used was qualitative interviews where we interviewed seven people living in Djuröhemmet who participated in all or parts of the project. The theoretical framework is Molins (2004) definition of participation, but also theories of meaningfulness, social needs and gerotranscendence were applied. The results indicate that the participants did not realize that their involvement during the planning helped developed the garden.

?Boverket? the Design Regulations in Sweden, also called BKR has for a long timebeen the mandatory standard that has guided and regulated construction design. Butat the end of 2010 BKR was replaced with Eurocode. This report deals with thecomparison of these two standards when it comes to wood construction. Duringwinter 2009/2010 there were many roof collapses due to excessive loads on theroofs across Sweden.

The EU-funded project European Cultural Heritage Online (ECHO) aims to integrateresources from various domains within the field of cultural heritage, and make them availableon the Internet. To accomplish this integration it is necessary to describe the various resourcesin a way that will achieve cross-domain interoperability. This description of digital resourcesis commonly referred to as metadata. The most well known and used metadata standard is theDublin Core Metadata Element Set, a general standard developed for the purpose ofdescribing all types of digital resources. Since the mid-1990's a large number of specializedstandards have emerged in different communities, for example IMDI, designed for detaileddescription of language resources.This thesis aims to examine the possibility of combining a general and a specialized metadatastandard to achieve cross-domain interoperability and at the same time provide a sufficientlydetailed description of language resources for researchers within the field of linguistics.

Syftet med denna studie är att få en insyn i vilket förhållningssätt fem verksamma grundsko-lelärare har kring användning av digitala verktyg i deras undervisning och hur det påverkar deras integrering. I Läroplanen för grundskolan, förskoleklassen och fritidshemmet 2011 fram-går det tydligt att handhavandet av digitala verktyg är en viktig del då skolan ansvarar för att varje enskild elev efter genomgången grundskola kan använda modern teknik som verktyg för kunskapssökande, kommunikation, skapande och lärande (Skolverket 2011a). För att nå syftet i denna studie har vi samlat empiri genom telefonintervjuer som sedan har tolkats och analyse-rats utifrån fyra valda teoretiska begrepp, IT, IKT, digital litteracitet och MIK. Studien visade att samtliga lärare förhåller sig positivt till arbete med digitala verktyg i undervisningen där det används som stöd för elevers lärande. Vidare framkom det att lärarna arbetade med olika kunskaper och förmågor utifrån de teoretiska begreppen.

Byggbranschen brottas idag med en hel del fel och brister i byggprocessen. Exempel på problem är bl.a. höga byggkostnader, kvalitetsbrister samt att det förekommer slarv och okunskap. Produktiviteten i byggbranschen har inte utvecklats lika mycket som i tillverkningsindustrin som använder sin ledningsfilosofi Lean Production.Syftet med detta examensarbete är att få insikt i vilka vanliga fel och brister som förekommer i byggbranschen, samt att kunna ge förslag till förbättringar i enlighet med lean-tänkande. När man talar om Lean i byggsammanhang benämns det Lean Construction.
