Produktionsplanering av tvättmaskiner

Most major companies today have a visual identity. It answers questions like: which font do I use? and when can I use the logo or not? Westinghouse Nuclear Fuel in Västerås have a visual identity but no guidelines for the employees to follow. Further-more, rollups and rollup handouts produced by Westinghouse are not mentioned in the visual identity. ?erefore the external information from Westinghouse is someti-mes, both by employees and customers, perceived as not uniform.

Styvföräldraskapet : ? Ett föräldraskap bland flera

The purpose of this study is to perform a description of how parents experience their life in a stepfamily and to examine how the parents experience the involvement from their new partner in the children?s upbringing. The issues are: (i) which expectations do the parent has on their new partner in the role as stepparent to the child, (ii) how active does the parent experience their new partners? step parenting concerning the stepchild and (iii) how does the parent expect the new family to take shape? A qualitative study has been done through interviews. The participants were sex biological parents, of which four were fathers and two mothers.

Påverkan på elektronik och sensorer i radiologisk miljö

The objective of this thesis is to make a training material for KSU, which shows how radiation affects the different electronic components in a radiological environment.All electronic systems in the presence of high ionizing radiation can experience difficulties and be destroyed.This influence may compromise the control system and thus the safety of a nuclear reactor plant.To achieve this objective requires a description of electronic components and sensors, to better understand its function.This thesis will also show the possible solutions available that the author found interesting.Organizations such as NASA, CERN and ESA have worked to develop electronic components immune to radiation. Those organizations have also developed a test protocol that guarantees to a certain extent the security of electronic components in a radiological environment.Since we know how the material reacts with the radiation, it could develop a material that can be resistant to radiation or like CMOS technology has proposed, to reduce the component to avoid the storage of charge in the oxide.Another solution can be the GRAPHENE. Its features will revolutionize the electronics and provide answer to the radiation problems, Graphene will replace Silicium and the electronic components will only have a few nanometers dimensions so the oxide area also reduces, and in this way avoid the known problem of storage of charge..

Effektiviseringspotential inom projekt

The work is performed at Forsmark Group AB as a final step in the Bachelor ofScience program in nuclear engineering at the University of Uppsala in 2013.The work is part of an ongoing process of streamlining project system model FKA.Streamlining the project model is an important aspect that affects all largecompanies that somehow have a project governing body when there is muchfinancial resources to save. Although the quality of the projects is positivelyaffected by efficiencyThe aim is to find possible common weaknesses and strengths of the project systemby interviewing a number of project managers, and using the systems in placeexamine the model.As part of the work also includes examining what project managers have to adjust tothe newly implemented system VPMM, and other newly introduced elements thathave been added to improve the efficiency in the futureProject System is a complex system that is influenced by many different parametersand participating individuals' attitude and personality. But then small changes in themodel could have major economic consequences.The thesis has generated results that show common weaknesses among the variousprojects and their project managers' general opinions about the project model. It alsopresents some possible solutions based on own thoughts and those interviewedobjects suggestions and comments..

Heteronormativ fantasy? En queerteoretisk analys av sex fantasyromaner

The aim of this Master?s thesis is to examine how six fantasynovels reflects or breaks the heteronormativity in society bylooking at how gender roles and sexuality are described.The theoretical framework is based on Judith Butler's theoryabout the heterosexual matrix which requires two separategenders and a compulsory heterosexuality and YvonneHirdman's two principles about dichotomy and hierarchy.The method used was idea analysis where dimensions basedon the theoretical framework were constructed. Thesedimensions were: behaviour, tasks, relationships and roles.The result shows that all of the books both breaks andreflects the society's values on gender and sexuality. Thereare some stereotypes present, for example that intuition isassociated with femininity and physical strength withmasculinity. However, the books also offer characters ofboth sexes that break the gender stereotypes, such asstrong women and emotional men.

Induktiv provning av ferritiskt rostfritt stå

The report examines the factors which may be a contributing cause to the problems that are present when ferritic stainless steel are eddy current tested in a warm condition. The work is carried out at Fagersta Stainless AB in Fagersta which manufactures stainless steel wire. In the rolling mill there is an eddy current equipment for detection of surface defects on the wire. The ferritic stainless steels cause a noise when testing and this noise complicates the detection of defects.Because of this, a study was made of how the noise related to factors such as steel grade, temperature, size and velocity. By observing the signal and with the possibilities to change the equipment settings the capability to let a signal filter reduce the noise level were evaluated.

Dokumentation av underhållssimulatorer för utbildning i vardagssäkerhet

At Forsmark nuclear power plant a new course called "education in everyday safety" has been started in an attempt to improve the safety culture. The goal is to spread the of expectations and approach the maintenance management has set, to all employees working at the plants. During the course, theory is mixed with practical tasks to reach a common view how work should be done to achieve safety for the plant and the people that work there.The practical tasks are done inside "maintenance simulators". They are built inside 20 ft containers which contains two dummy pipe systems. On the pipe systems some valves, a flow meter and a pump has been installed.

En titt på konsten Hur ser boråsarna på sin offentliga konst?

This thesis explores how public art is received by the general public in Borås, Sweden. As a point of departure it was assumed that a study of the local papers would offer an accurate insight in to the debate of public art. Hence, press clippings were chosen as primary source material together with the works of art. The questions addressed in the study are: what is written in the local daily press about public art? Who writes in or makes statements to the local dailies about public art? Textual analysis is the predominant method employed while hermeneutics is the underlying theory.

Påverkar behandling med magnettäcke beteendet hos friska hästar?

Magneter har använts långt tillbaka i tiden för att behandla olika åkommor. Det senaste årtiondet har de fått ett uppsving som en alternativmedicinsk metod. De påstås ha olika medicinska effekter så som att ge ökat blodföde och verka smärtlindande och avslappnande på ömma muskler. Syftet med den här studien var att studera huruvida hästtäcken med 120 stycken insydda permanenta magneter (à 900 gauss) har någon effekt på beteenden hos hästarna vilka tyder på en ökad avslappning. Sju normala, friska hästar inkluderades i en prospektiv, randomiserad, blindad, placebokontrollerad cross-over studie.

Konstruktion av säkerhetslagerför svänghjul

This thesis is the result of the investigation and solution of a mechanicalproblem regarding flywheel malfunctions. A flywheel is, in short, a devicethat relies on a rotating object?s moment of inertia to store energy overshort time spans. This project is part of the development of a fourthflywheel prototype at the division for electricity at Uppsala university,which uses magnetic levitation to keep a hollow cylinder rotating at veryhigh speeds inside a vacuum chamber. Should the magnets fail however, orsome other error occur that leads to an uncontrolled state of rotation, thecylinder needs to be stabilized mechanically by a device usually referredto as ?back-up bearing?.

Före och efter Fukushimaolyckan : Svenska dagstidningars rapportering om kärnkraft

Den 11 mars 2011 inträffade en kärnenergiolycka i Fukushima, Japan. Jag har gjort en diskursanalytisk innehållsanalys av fyra svenska dagstidningars artiklar om kärnenergi från de 90 dagarna innan kärnenergiolyckan i Japan, de första 90 dagarna efter den samt de därefter följande 90 dagarna. Jag har även jämfört de tendenser som framkommer i rapporteringen med Sveriges befolknings attityder till kärnenergi för att se om det finns något samband mellan dessa. Syftet var att utifrån mina resultat, tidigare forskning och teorin från forskningsfältet ?communication of science? analysera den eventuella påverkan medias rapportering om kärnenergi och allmänhetens syn på kärnenergi kan ha på varandra.

Utvärdering av beräkningskoden APROS för användning i inneslutningsanalyser

At Forsmark nuclear power plant the rather old-fashioned software COPTA is used in containment safety analysis. There exists a desire within the organisation to introduce a more modern software with ability to more detailed modeling and increased usability.The goal of this thesis was to evaluate the software APROS in containment safety analysis. APROS models describing one of the containments at Forsmark NPP have been developed. Two simulations of typical containment incidents, one of them a large pipe break, have been made where containment safety parameters such as pressure and temperature are studied. Results are analyzed and verified against results from corresponding COPTA models.

Normalitet i adoption och föräldraskap : En kvalitativ studie av socialtjänstens medgivandeutredningar av ensamstående som vill adoptera

The aim of the study was to illustrate how single parents who want to adopt a child are described in consent investigations made by the social service. The methodology for this study was document analysis. The analysis material consisted of 23 consent investigations from family courts in 12 different municipalities and district administrations. The theoretical starting point of the study was the perspective of social construct of reality. Based on the issues of the study, background on international adoptions, theory of norms and deviation and past research the documents were analyzed.
