AbstractThis bachelor?s thesis at the Department of Production Engineering at the Royal Institute of Technology in Stockholm deals with the subject of automated metrology. The degree of automation of tasks within production has been a growing trend but the measurement of quality has not followed the same trend. The main thesis follows:What incentives are there to automate the measurement of quality in production?What factors are crucial and why are not all metrology automated?The thesis comes along with a number of sub-queries and delimitations.The working method includes both theoretical and empirical studies.

Syftet med detta examensarbete var att utvärdera tre olika metoder för mätningav energiomsättning hos människokroppen med förhoppningen att kunna komma fram till en enklare metod vilket kan underlätta främst för patienter men även för sjukvårdspersonalen. Utvärderingen grundas på mätningar av BMR.Det finns flera olika metoder att mäta energiomsättningen och jag har använt mig av indirekt kalorimetri (referensmetod), bioimpedansmätning (BIA) och Sensewear Armband. Den sistnämnda är en helt ny metod och det är denna metod som främst har utvärderas gentemot de andra. Mätningarna med alla tre metoderna utfördes vid samma tillfälle efter fasta för varje försöksperson (n=10)och patient (n=2). Armbandet bars i tre dygn, indirekt kalorimetri mättes under 30 min och BIA mättes vid ett tillfälle.

This thesis examines history of the subject of mechatronics and innovation. The main reason tostudy mechatronics from a historical point of view is that it has never been done to a greater extent before. An overview is justified because various definitions have been used over the decades, but nowadays the subject has become more established. Focus in this thesis is mainly on development of the subject of mechatronics at Royal Institute of Technology in Stockholm. Innovation is the other aspect of this thesis.

Kunskapsöverföring är en nödvändig förutsättning för att säkerställa organisationers existens och framåtskridande. Utgångspunkt för denna uppsats är förstudiens roll i mjukvaruprojekt och dess betydelse för den fortsatta systemutvecklingsprocessen. Fokus liggerpå kunskap som genereras under förstudien, samt hur och i vilken omfattning kunskapen förs vidare till analysfasen i systemutvecklingsprocessen. Resultatet visar att förstudien utgör ett viktigt beslutsunderlag och är en nödvändig förutsättning för att gå vidare i systemutvecklingsprocessen. Kunskapsöverföring genom dokumentation och via muntliga föredragningar är otillräcklig, eftersom det finns ett ?filter? som innebär att erfarenhetsbaserad kunskap inte överförs mellan förstudie och analys via dokument eller via muntliga föredragningar.

The main objective of this thesis was to develop appropriate strategies and find factors that affect the usability of parameterized designs. This was accomplished by investigate the user-interface and how it is designed to meet the user's information needs. The thesis also embraces the basic theories in terms of investigation, cognitive design principles and human behavior patterns in the interaction with the machine. The approach has led to an explorative investigation in this subject area.The thesis also had the purpose to achieve more efficient ways for development of motor chainsaws at Husqvarna AB's department Global Cutting Equipment. That can be achieved through reduce costs of development per sold unit.

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.

Students at Jönköping School of Engineering were given an assignment from Jönköping municipality, to evaluate their decision support system, QlikView. The students have also developed proposals for improvement with focus on usability.The Jönköpings municipality has currently got 11000 employees and consists of nine different administrations. The target group for QlikView is approximately 600 first-line managers.The intention of QlikView is that the users can get an overall picture of their business by having all information in just one system.The purpose of the thesis is to obtain a picture of what the users think about the system today and present relevant suggestions for improvement, which the Jönköping municipality can use when the introduction of the new version of QlikView takes place. The research questions that the study aims to answer are:? Has QlikView got a user friendly interface?? 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.
