Av vår uppdragsgivare SOMAS i Säffle har vi fått uppgiften att konstruera ett bottenlock till kalottventil DN500 PN25. Vårt mål med arbetet är att minimera vikt och bearbetnings kostnad för locket. Materialet består av CF8M enligt Amerikansk standard.[2] Locket ska godkännas enligt SS-EN 13445-3:2002.[1] För FEM-analys används bilaga C design by analysis. [1]Locket ska analyseras i 3 lastfall.  Täthetsprovning av sätet, påverkar locket med en radiallastTryckprovning, påverkar locket med en övertryckslastDrift baklänges, både radiallast och inre övertryck Med utgångspunkt från kalottventil DN500 PN10, som har identisk axel och kalott, analyserades locket till DN500 PN10 i Abaqus med övertrycket 25bar. Där locket inte uppfyllde kraven sattes stödfjädrar för att styva upp locket.

Saab Bofors Dynamics AB is looking for ways to let the employees work wireless in the future. The security in Wireless Local Area Networks (WLAN) has not been considered very reliable, but new standards and protocols have been developed to enhance the security in WLAN. Since most wireless components soon will have built in support for wireless communication, it is important to have a model to deal with secure wireless communication ready. This is necessary because it is important to protect the company?s information related systems, ensure contingency in the daily work and maintaining the trust of the market and the authorities.

Goodwill är ett omtvistat ämne inom redovisning. I dagens samhälle har företag haft friheten att kunna välja vilken regel i anknytning till goodwill de vill använda och det med hänsyn till vilket resultat de eftersträvar. Våren 2004 offentliggjorde International Accounting Standard Board en ny standard, IFRS 3 för redovisning av företagsförvärv. IFRS 3 går ut på att goodwill inte längre är föremål för planenliga avskrivningar utan istället ska företag genomföra ett ?impairment test? som innebär att företagen genomför en ingående analys av goodwillvärdet årsvis.

This thesis looks at two sides of the same coin: how to support the production and future development at a specialist medical technology department at Danderyd Hospital. The two sides are; a pilot study of a product management system (PDM) and an interview based study on the characteristics of the silent knowledge of the technicians. The department (National respiratory centre, NRC) is facing retirement of several key employees.The technical study shows that the success of an implementation is largely dependent on the users? prior knowledge and use of a 3D Computer aided design system (CAD).The system itself is shown to fulfill the Lifecycle requirement of tracking the products (mostly tracheostomy tubes) but without a CAD centered workflow, some substantial education and preferably some new recruits, an implementation of the PDM system will fail. The author recommends development of the current ?low-tech? system of MS Excel and Access rather than redistribute the dependency from technician towards a complex, commercial software and its vendor.The analysis of the technicians? silent knowledge with the newly developed method, epithet for silent knowledge (ETK), shows that the longer employment time:the more differentiated technicians become in describing their work,practical knowledge are regarded higher andthe social and collective problem solving factors of the work becomes more important.Typically, it is shown that a new employee should preferably enjoy problem solving, being pragmatic and social as well as having some prior education or work experience in a CAD and/or a PDM system..

This thesis of 15 hp has been implemented at Halmstad University, incollaboration with Saab Dynamics in Linköping. Saab Dynamics is a companyoperating in the defence industry where competition is tough. This necessitatesnew ways to increase efficiency in the company, which is the basis for this thesis.Saab Dynamics wants to introduce simulation driven design. Since SaabDynamics engineers have little experience of simulation, required a usermethodology with clear guidelines. Due to lack of time, they chose to assign thetask to students, which resulted in this thesis.The aim of the thesis is to develop a methodology in mechanical design, wherethe designer uses the FE analysis early in the design process to develop thestructures' mechanical properties.

Forskning kring tillväxten av leasing har idag resulterat i att leasing omfattas av en femtedel av den totala externa finansieringen företag väljer att anskaffa tillgångar på. Ett företags finansieringsmöjligheter sätter prägel på huruvida företag överlever på marknaden idag. Då leasing är ett av de mest attraktiva finansieringsalternativen var det högaktuellt att undersöka vad leasing var samt hur redovisningen skiljer sig åt av leasing mellan företag och länder. Den stora frågan som företag måste ta hänsyn till är om de ska lånefinansiera eller leasa sina tillgångar. Rent teoretiskt är dessa förfaringssätt likartade vad gäller kostnader och betalningsansvar.

The ?peer to peer? (P2P) is a technology of downloading and filesharing between online - Internet - users by the mean of specified software. Since June 1999, the Napster software has made the happiness of millions of individuals who used it to obtain and share free audio files Mp3. Rapidly, the major recording companies have prosecuted the Napster Company and managed to force it to close down. They were arguing against it for it is supporting the development on a large scale traffic of files protected by copyright and thus was threatening the whole music and movies economic world.

This thesis work aims to describe the prerequisites for a distributed treatment platform for real-time sharing of rounds performed by paediatric oncologists. The work started during the autumn 2004 and is directly aimed at improving the situation for the thirty or so specialist treating children with cancer. The work is not limited to the description of such a platform but also to select suitable software and hardware for the implementation of the platform and further more to coordinate the implementation. The production of several documents describing the platform is also part of this work. The work successfully led to the implementation of such a platform as described in the published article Barnradioterapi på distans Kristenssen et.

The aim of this thesis is to map the current internal information flow at Volvo Uddevalla, to detect obstacles in the flow and to find out how these obstacles can be avoided. The aim is also to describe how a corporation, in this particular case Volvo Uddevalla, creates knowledge and use information. The study is performed in order to create a base for the coming implementation of a new information standard. The method used is conducting an information audit investigating the current management of documentation according to the changes that have to be made to carry out the claims from the standard. The investigation is made by way of interviews with 16 of the employees at Volvo Uddevalla.

Swedish studies have shown that more people than expected have problems with leg ulcers and that the yearly cost for treatment per patient is approximately 26 500kr. Since the elderly population is on the rise, there is a need to highlight this growing problem, to make sure that proper assessment tools are used and to improve the standard of care given to patients with leg ulcers. The aim was to show what a difference the nurse can make to patients with leg ulcers. With all types of wounds it is imperative to establish if there is any underlying reasons since certain illnesses can cause more wounds or delay the healing process. The doctor is responsible for making the diagnosis and to prescribe the correct treatment whereas the nurse?s responsibility is for the nursing care and its documentation.

Today?s society is one where technological advances are made daily, which increases the need to stop and assess the risks against users? integrity when integrating new technology in contemporary systems all the greater. We have taken two technologies, Near Field Communication and Certified Wireless USB, whose envisioned area of use is to be integrated into mobile phones, and evaluated what security threats are revealed for the respective technologies. The threats against security have been identified through research of the standards and existing reports for each technology. Practical experiments have not been conducted on account of us not having access to any equipment to run such trials.

Sammanfattning EDI är ett välkänt och beprövat sätt för företag att automatisera sina affärsprocesser. Det är också välkänt att EDI är dyrt att både inverstera i och att använda. EDI anses också som krångligt att lära sig och att förstå. Detta har gjort att EDI aldrig riktigt har slagit igenom bland små och medelstora företag. Det internationella standardiseringsprojektet ?ebXML?, som sponsras av bland annat av UN/CEFACT och OASIS, har släppt ett ramverk för hur XML ska kunna användas för elektronisk handel, även B2B.

This report has been performed for WSP Construction Design located at Arenavägen 7 in Stockholm. WSP Construction Design is one of the leading departments in Sweden in construction solutions regarding everything from building construction to industrial building. Great competencies regarding steel, wood and concrete constructions are available within the department which is well sought.Crane girders used in the industry are exposed to large loads that vary over time that includes instantaneous lifts and the crane girders movement which lead to the phenomenon fatigue in the crane girder and its ingoing welds. A control of fatigue needs to be performed after a certain lifespan measured in time which in turn is converted to a number of loadcycles. When the number of loadcycles amounts to a greater number the input welds resistance will have been reduced and the rate of utilization thereby increased.
