Examensarbetet visar en selektivbedömning för lågspänningställverk T15 på SCA Edet bruk. Ställverket har ett 40 tal motordrifter och matas av en 690V transformator på 3,5MVA. Grundprinciper för de vanligaste lågspänningsskydden presenteras samt mer specifika detaljer om installerade skydd i aktuellt ställverk. Olika typer av selektivitet är kortfattat presenterat i rapporten. Vid beräkning och dokumentering med hjälp av datorprogrammet Febdok visade det sig att installerade skydd inte fanns med i programmets skyddsregister.

Voltage sag indices are a way of quantifying the performance of the power supply, as far as voltage sags are concerned. Indices can be defined for individual events, for individual sites, and for a whole system. A standard method for single-event methods is part of IEC standard 61000-4-30.This thesis emphasizes the importance of voltage sag indices and different methods for calculating three-phase voltage sag characteristics. Three-phase events measured in a medium network voltage over period of one month were analyzed, results examined and statistically evaluated. An algorithm for calculating voltage sag characteristics and indices was created in Matlab.

IT (Informationsteknologi) används i dag mycket för att distribuera och förmedla information internt och externt. Ett bra verktyg för informationshantering är verksamhetens intranät. Arbetet handlar om användbarhet i små SharePoint-projekt. Med användbarhet omfattas faktorerna användarvänlighet, anpassning och användaracceptans. Små SharePoint-projekt (på under 300 timmar) innebär att det finns mindre resurser för att tillämpa användbarhet.Syftet med detta arbete är att undersöka utvecklare inom SharePoint sina åsikter och förhållningssätt kring användbarhet, samt hur användbarhet bäst kan uppnås i små projekt med begränsade resurser.

Atlas Copco Tools develops and manufactures handheld industrial tools. Heat and surface treatments are used to provide the tools with certain properties. There are no routines for the choice of treatment or for how to specify treatment on drawings. Production documents that are sent for production abroad may not be clear enough. Some treatments are known as trademarks and there are no instructions for how to specify these on drawings and in CAD-models.The purpose of this master thesis work is to create recommendations for the procedure of choosing heat and surface treatment.

To be able to maintain an adequate ITservice for various users and needs,more municipalities are looking at thepossibility for mergers of local ITdepartments. One solution for mergingmultiple services/functions and creatingsynergy opportunities is called SharedService Center (SSC). The concept of SSCis that the administrative serviceitself becomes a core activity withinthe organization. The aim of this thesisis to provide municipalities who areconsidering a merging of their local ITdepartments with recommendations on howto design the Shared IT Service Center.Recommendations are outlined based on ananalysis of IT-management literature,reports and by conducting a study onthree ongoing collaborations.The conclusions drawn from the studysuggest guidelines for the design of aShared IT Service Center formunicipalities. These are as following:Create a vision associated with aspecific and structured target state.Identify needs for different targetgroups in municipalities and set acommon standard.Create a clear and practical model/SLAappearance of the cooperation andagreement.Ensure the individual municipalitiescommissioning skills in order to notlose it in the context of a common IToperation.Find an organization that is democraticfor member municipalities andfacilitates long-term partnership.Specify the operation and maintenance sothat it can be regulated and controlledEstablish a common help desk.Establish a common standard andconsolidated infrastructure before theintroduction of a common technology platform..

The ISO 9000-series is a set of quality standards created by the International Organization for Standardization. The series is intended to provide guidance to companies in the process of deploying an effective quality management system. The series includes the requirements standard ISO 9001. This standard contains requirements on how a quality management system should be designed and how companies generally must work with quality issues. When a quality management system is introduced, if wanted, a quality certification can be implemented.

ABB and Prevas have initiated a collaboration to sell a system to optimize steel industry furnaces, called FOCS. The purpose of this thesis is to investigate possibilities for integrating Prevas FOCS and ABB 800xA.The result of the investigation is used for an implementation of a prototype of the integrated system. The study shows a general method that can be used when implementing two software systems. The prototype of the integrated systems is made with usability principles in mind. This is a very important aspect in order to create a good working environment for the operators of a steel plant.

Över hela västvärlden blir hälsoproblem som hänger ihop med övervikt och för lite rörelse allt vanligare, därför har många länder börjat med att försöka få befolkningen att röra sig mer. Vandring kan vara en lösning på detta problem och därför har man i Jönköpings län börjat se över sitt vandringsledssystem. Gislaveds kommun, i Jönköpings län, har uppmärksammat detta problem och inlett ett arbete med att hitta lösningar för en modernisering och restaurering av Gislavedsleden.Syftet med denna uppsats är att utföra en observationsstudie och analys av Gislavedsleden och framlägga åtgärdsförslag där de behövs. Med hjälp av Rainer Brämers empiriska undersökningar om vandring och vandringsleder, Patrik Grahns parkkaraktärer och Kevin Lynch analysmetod studeras ledens upplevelsevärden. Analysen resulterar i förändringsförslag som kan förbättra ledens upplevelsevärden.

Cykling f?r transport har potential att vara en del av h?llbara st?der och samh?llen genom att bidra till h?llbara transporter och fr?mja fysisk aktivitet. F?r att ?ka transportcyklandet arbetar planeringsakt?rer med att vidareutveckla utvalda cykelv?gar till s? kallade supercykelv?gar. Vidareutvecklingen best?r dels av upprustning av cykelv?garnas standard och av att synligg?ra dem genom gestaltning bland annat i form av enhetlig v?gvisning.
