How can the interface be improved to become more user friendly?Theories that this work is based on is Jacob Nielsens ten usability principles and Ben Schneidermans eight golden rules.

In the EU there are EC Directives that Member States of EU should follow. Sweden has undertaken to transpose EC Directives regarding the working environment to Swedish Provisions.  In 4 April 2006, the European Commission had some criticism against the Swedish implementation of the Construction Sites Directive. The Swedish Work Environment Authority has in response to this criticism reworked the Work Environment Act and related provision about building and civil engineering work. The changes came into force 1 January 2009.These changes have resulted in some working methods and even new responsibility subjects must be reviewed. The purpose of this exam project was to investigate if contractors and clients in the construction sector, had have time to update themselves on this front and adapt to these changes.

This thesis is about developing a design that provides improved vacuum seal between a lead coating and a plastic coating during plastic extrusion processes of cables. This report is a part of the course MSGC 17 for Bachelor Engineers in mechanical engineering.The work is performed at Nexans Norway AS in Halden where they have a production of high voltage cables for sea-, and offshore industry. A problem they face is that they do not get enough good seal at the attachment to the plastic extrusion machine. They want to achieve a vacuum between a lead coating on the cable and a plastic coating of the cable for plastic extrusion, which is something they do not achieve today. The thesis is thus to come up with a design that provides better sealing against the cable.The work involves a construction part with the phases of product development processes.

The euthropthication of the Baltic Sea is a threat that is beginning to be taken seriously by the governments concerned. In Sweden, regulations concerning the allowed nitrogen (N) concentration in the effluent water from wastewater treatment plants are being tightened up. The Rimbo wastewater treatment plant has been imposed to reduce the annual mean concentration of total N in the effluent water to levels below 15 mg l-1. A more and more common way to reduce the nitrogen level in wastewater is to let the water pass through a wetland. This study investigates the possibility to build this kind of wetland at the outlet of the Rimbo wastewater treatment plant.A prestudy of the topography, soil characteristics and groundwater flow indicates that the land area in question is well suited for the construction of a wetland.

AbstractConcrete foundation slabs are usually exposed to unilateral drying during the curing process. The unilateral drying causes an axial shrinkage and a concave curvature of the construction. The curvature results from the fact that the upper part of the slab is drying and shrinking faster than the lower part. This is called gradient shrinkage.A problem occurs when the slab is considered fully restrained by adjoining structural parts. The deformations caused by axial contraction due to the constant part of the shrinkage and the curvature caused by gradient shrinkage of the slab are then prevented by the fact that the slab is fully restrained.

Denna magisteruppsats redogör för en anpassning av COCOM (Contextual Control Model) till flygledningsdomänen. COCOM är en modell som kan användas för att beskriva och förutse kontroll hos operatörer i komplexa system. En central del av modellen är begreppet kontrollnivå vilket beskriver hur graden av kontroll hos ett JCS (Joint Cognitive System) beror av och påverkar de parametrar som beskriver dess prestation. Fokus i denna uppsats ligger på det JCS som omfattar flygledaren i sin arbetsposition.I uppsatsen anpassas Hollnagels generella beskrivning av kontrollnivåer i COCOM till flygledningsdomänen. Till grund för anpassningen ligger en kvalitativ studie i form av observation och intervju av sju operativa flygledare vid en svensk kontrollcentral.

This report is the result of a degree project in building engineering, at an advanced level. The project evaluated a building from a technical and historical point of view, and focused on its energy consumption, particularly the energy used for heating. The building in question was a small apartment building in Strömsholm, Sweden. It was made in 1902, from vertical logs, a not so common form of the traditional log house. The goal of the project was to evaluate if the energy consumption could be reduced in accordance with building preservation regulations, that is without damaging any of the building?s cultural or historical values.The building was surveyed with the help of archive and literature studies, interviews and inspections.

Vid Industriellt UtvecklingsCentrum i Olofström AB utförs bland annat slitageprov av verktygsstål vid plastisk formning av plåt. Parametrar som undersöks är verktygstålsmaterial, plåtkvalitéer, ytbehandlingsmetoder, smörjning och olika kombinationer av dessa faktorer. Den nuvarande testmetoden upplevs av IUC som icke tillräckligt produktionslik. Därför skulle det vara önskvärt med ett mer produktionslikt slitagetest än det nuvarande. Vårt uppdrag var förutom att utforma ett nytt slitagetest även att undersöka intressenters synpunkter på den nuvarande testmetoden och önskemål om ett framtida slitagetest. Inledningsvis inventerades befintliga slitagetestmetoder för att försäkra sig om att särskilja det nya testet från befintliga testmetoder och kartlägga vilka egenskaper som undersöks. Eftersom önskemål om ett mer produktionslikt slitagetestmetod fanns behovet av att göra en studie för att definiera begreppet mer produktionslik.

Som grund för denna uppsats ligger en tidigare undersökning med titeln Undersökning av mental arbetsbelastning under instrumentflygövningar (Andreas Johnsson, 2004). Denna uppsats utgör en fortsättning på ovan nämnda undersökning. Liksom i Johnssons (2004) undersökning har en subjektiv mätmetod baserad på en niogradig skala använts för att utvärdera svaren på den enkät som använts för att få fram data. I denna uppsats undersöktes samma kurs som i den tidigare undersökningen. Det vill säga studenterna i kurs 03:2 vid Trafikflyghögskolan, Lunds universitet.

Background and problem: The abolishment of the mandatory audit in Sweden resulted in a marketorientation in which the small sized enterprises gained a stronger position. Theaudit firms are faced with the challenge to better meet the clients need and todemonstrate the value of audit now when it is optional. In coherence with thisclient focus it is endorsed to implement a value-based pricing that primarilyconsiders the client?s value and willingness to pay. The value of audit andaccounting services to small sized enterprises is not yet fully investigated, whyit is difficult to implement a value-based strategy.Aim: The aim of this study is to investigate the value of audit and accounting servicesto the small sized enterprises through the study of which attributes theseservices consist of and which priority the small sized enterprises attach to thedifferent attributes.

Hur kan man skapa en fungerande, kostnadseffektiv distributionslösning för direktleverans med en hög servicenivå för att tillfredställa kund- och konsumentbehovet? Problemet kan delas upp i en teoretisk och en praktisk del. Den teoretiska delen är att det inte finns en generell lösning på problemet. Det praktiska problemet är att företaget vi studerar, Lifebox, idag inte har någon lösning.Syfte Huvudsyftet med examensarbetet är att ge Lifebox förutsättningar för en fungerande, kostnadseffektiv distributionslösning med direktleverans med en hög servicenivå för att tillfredställa kund- och konsumentbehovet. Vi har också definierat ett delsyfte vilket är att skapa förståelse för de krav, behov och förväntningar som finns i Lifebox och dess intressenter.Metod För att uppfylla detta syfte måste vi använda oss av en metod som möjliggör att vi kan studera ett projekt i förändring och som samtidigt ger en lösning som knyter an till verkligheten i ett så brett perspektiv som möjligt.

The situation at Plastal AB is following; the plant in Simrishamn has not capacity enough but the plant in Kristinehamn has unused capacity. My task with this master thesis is to build a logistic flow between this two plants, optimize purchase quantities and ensure delivery safety.The production of the Intermediate Section (LS) will be divided between the plants. The LS will be produced in the following way; the injection moulding process will be done in Simrishamn and the assembling and lacquering processes in Kristinehamn, The reason to divide the production is to ensure delivery safety. Plastal AB can not move the whole production of the l.S because the two plants have different processes (moulding res. injection moulding).When the 1.5 has been transported to Kristinehamn following moments are included in this order; lacquering, welding and assembling.

Den här kandidatavhandlingen undersöker fördelarna och begränsningarna med Internetbaserade operativsystem i molnet, så kallade Internet OS, och hur IT-företag ser på ämnet. Internet OS är operativsystem som placerar sina resurser och processorkraft ute på Internet, ofta med hjälp av olika molnettjänster. Det finns problem och utmaningar med Internet OS. Dessa problem kan vara ett hinder för företag att överge de traditionella operativsystemen, som exempelvis Windows, och övergå till Internet OS. Det saknas undersökningar om IT-företag vill eller kan flytta sin verksamhet till molnet. Vi vill ge en tydligare bild och bidra med ny kunskap om företags syn på Internet OS. Arbetet har genomförts med en litteraturstudie som har fokuserats på vad den akademiska världen vet om Internet OS med fokus på Chrome OS. Litteraturstudie går in på fördelar och nackdelar, samt framtida visioner.

Environmental destruction is a growing problem in our world. Almost every day there are new reports concerning that we have to do something about the greenhouse gasses. Simultaneously is the human constantly more eager to have a life with higher standards and therefore uses more energy. The environment is a question that is highly up-to-date and more people try to find solutions on how to save our planet. One way to decrease the energy demand is to build passive houses, where the houses don?t have any active heating.
