Dokumenthanteringssystem inom byggbranschen
One of the aims of this report has been to make an inventory of the building trade market to see which document handling systems that are available. The secondary aim was to document the users´ demands on the systems and other demands such as quality assurance. After this, the document handling systems Byggnet and Lotus Notes, which are rather complex systems, have been analysed. Finally a recommendation has been made. In the inventory of the marketthe internet has been used because it is there the latest information can be found.
It-säkerhetsmedvetenhet hos gymnasieungdomar : En kvantitativ studie om it-säkerhetshot och risker för Internetanvändare
Syftet med denna studie är att ta reda på hur medvetna gymnasieelever är om it-säkerhetshot och risker på Internet. Detta har gjorts genom att först undersöka aktuella hot genom att studera trendrapporter från ledande it-säkerhetsföretag. Denna information har sedan använts i en enkät för att ta reda på kunskapen och medvetenhetsnivån om dessa it-säkerhetshot bland gymnasieelever i Uppsala. Studien visar att det finns ett behov av utökad kunskap inom området. I resultatet kunde särskilda brister ses i de sociala aspekterna av it-säkerhet.
Utveckling av nytt koncept till processmaskin
Metso Paper offers a front-running range of solutions and services for the pulp and paper industry. At the baling unit, design solutions are developed for manufacturing and handling of pulp bales. The machines are continuously developed to satisfy customer needs. One big step in the development of the baling line was to remove hydraulics from the machines and replace it with electrical motors and pneumatics. This was not done on the folding machine which is still driven by mainly hydraulics.
Effekt på mark och gröda av olika bearbetningssystem, med och utan CTF
Swedish agriculture has gone through big changes in the latest 60 years. The farm sizes have increased, which has led to raised tractor and machinery sizes and therefore
increasing problems with soil compaction. A method to reduce these problems is to implement controlled traffic farming, CTF. All field operations are then concentrated
to specific tracks by using GPS guidance.
The aim of this work was to study how the tillage regime, with or without CTF, affects the soil, with the main focus on macroporosity. In Säby close to Uppsala, and Alnarp close to Malmö, randomized block trials has been carried out, and the data has mainly been taken from these trials.
Brandskydd av stålprofiler
Denna rapport är resultatet av en studie kring kostnader för brandskydd av stålprofiler. Rapporten inleds med en beskrivning av problemet att hitta den ekonomiskt bästa lösningen för brandskydd av stålpelare i en konstruktion med specificerad brandklass. Därefter följer en allmän del om brandskydd och en övergripande redogörelse för gällande lagar och föreskrifter som har betydelse för brandskyddsdimensioneringen. De laster och förutsättningar som ligger till grund för valet av pelardimensioner beskrivs och valda dimensioner redovisas i tabell. Därefter följer en beskrivning av de brandskyddsmaterial som studerats: inklädnad med gips-, fibersilikat-, och stenullsskivor samt brandskyddsmålning.
Kvinnlig chef i byggbranchen : faktorer som utgör hinder till avancemang
Background: Studies that have been made in male-dominated organisations shows that only few women have succeeded in advancing to the higher positions in all businesses. Statistics shows that merely 4 % of the managers in all building companies are female. The manager role has earlier always been classified as most suitable for men resulting in barriers for women who strive for management positions. This problem is now very renowned and is called the glass ceiling. To improve the current situation, both the organization's structure and culture, have to be modernized for more women to succeed and get the courage to get into the industry.
Översvämningsrisker längs Funboån
Flooding events are no longer rare, floods occur all over the world. Accordingly, it is vital for the society and different authorities to work with flood mapping. To meet the goal of Uppsala kommun to map the risks of floods in Uppsala län, a map of the different areas around Funboån which are inside the area of risk for flooding have been developed.In the work, cross sections and the water flow have been measured. Moreover, an echo-sounding have been carried out in Funboån to map the bottom topography. From the bottom map and laser scanned data covering the study area, a terrain model was created.
Programmering av testrigg för marindrivlina
Marinediesel Sweden AB i Ängelholm tillverkar och utvecklar båtmotorer och motorbåtsdrev. Jaggjorde mitt exobb på avdelningen MD Engineering som huvudsakligen utvecklar marina drivlinor.Marinediesel Sweden AB var i behov av ett styrprogram till den testbänk de byggt för att kunna testasina motorbåtsdrev. Denna rapport beskriver arbetet jag utfört för att färdigställa och optimera ettstyrprogram till en testrigg för marina drivlinor. I rapporten tar jag upp drevbänkens uppbyggnad, dessfunktion samt de problem jag stött på på vägen. Bland annat beskrivs hur effektförlusten beräknasmed energidifferensen i tillförd och bortförd olja i drevet, samt hur det pålagda vridmomentet, somsimulerar belastningen vid verkliga driftsförhållanden, styrs och beräknas med endast trycket ihydraulcylindrarna..
Bestämning av dagvattenflöden i Knivstaåns avrinningsområde
The purpose of the thesis was to map the hydraulic load on the Knivsta river from stormwater runoff, and build a platform for further studies of pollution loads on the rivers ecosystems. New residential areas are planned to be built in Knivsta municipality and it will have an impact on stormwater flows to Knivsta river. To examine the impact this will have, simulations were made in the area as it stands today and after expansion work. The work includes calculation of flows from the populated areas but also from the catchment area around it consisting of woodlands and fields. Because of expected climatic changes which may affect rainfall, the simulations have been performed with different return periods for rainfall data.

Analys av Husqvarna AB:s lastbilstransporter till Italien
The thesis has been written as a part of the Bachelor degree in Industrial engineering and management at the School of Engineering in Jönköping. The work is focused on the part of Husqvarna AB?s supply chain that is associated with the lorry transports to Italy. Husqvarna AB has approximately ten Italian customers, whose delivery patterns have been studied from January 2007 to July 2008. Some of the customers have a low delivery frequency and small amounts of goods that they therefore have not been fully analyzed in this report.
Konstruktion av truckmonterad hjulhanterare
GBD-Storage Systems is a company that provides the industries with products for efficient storage.The company produces pallet racks and accessories like cassettes and extending units. The companyhas also supplied tire racks for a number of tire companies. The company's CEO Gunnar Berglund hasfor some time had an idea to improve the working situation of the workers on tire firms by allowingthe wheels to be handled by a counterbalance truck. The current situation poses numerous heavy liftswhen the tires are handled and therefore is hurting the workers.This thesis has been aiming at helping the GBD-Storage Systems by developing a concept of howan accessory to counterbalanced trucks can be designed to cope with the wheels. This concept willthen be produced as prototype by the company.

Lojalitetsprogrammet Eurobonus fall inom det svenska inrikesflyget
Den 30:e september 1998 mottog Konkurrensverket ett klagomål ifrån Braathens Sverige AB, enligt vilket SAS (Scandinavian Airline System) anklagades för att på olika samverkans förfarande missbrukat sin dominerande ställning på den svenska inrikesflygmarknaden. Några veckor efter klagomålet från Braathens beslutade Konkurrensverket att avsluta klagomålsärendet och istället på eget initiativ pröva SAS förfarande. Den 12:e november 1999 beslutade Konkurrensverket att SAS inte fick tillämpa sitt Eurobonussystem på inrikeslinjerna där det fanns andra konkurrenter. I praktiken rörde det sig om linjerna Stockholm-Göteborg, Stockholm-Malmö samt Stockholm Sundsvall..
