This report contains a degree project made by the mechanical engineering students Lennart Andersson and Daniel Jansson. The project has performed in assignment by SOMAS Valves AB in Säffle. SOMAS are leading in development on control and on/off valves. To maintain this position they always want to improve their products. One way in this development is valves that are more tightened.The purpose with our project was to investigate another seat design on a HiCo (High Cobalt Alloy) seat to a SKV 150 PN 25 valve and compare this to an original HiCo seat.By modifying the seat on a ball valve we want to achieve a valve that leaks lesser then a valve whit original seat.

Jag kommer i denna uppsats beskriva den designprocess som pågått vid skapandet av en webbaserad informationsplattform från koncept till slutprodukt.Mitt uppdrag har varit att effektivisera en webbyrås nuvarande sätt att hantera och sprida information på, som bestod av en blandning mellan digital och analog information, och skapa en ny webbaserad informationsplattform. Den nya webbaserade informationsplattformen ska kunna samla all information på en plats och skapa ett effektivare informationsutbyte mellan de anställda på företaget.Jag har använt mig av två teoretiska ramverk; Nielsens tio heuristics samt Krugs visuella design hierarki.Jag har arbetat nära beställaren för att kunna skräddarsy webbplatsen till deras behov.Resultatet efter ett omfattande arbete med designmallar och front-end kodning blev grunden för webbyråns webbaserade informationsplattform, utvecklad för att effektivisera spridningen av information på företaget..

Föreliggande studie omfattar en jämförelse mellan sättningsberäkningar med datorprogrammen FEM Design 11 (senast kommersiella versionen) och FEM Design 12 (betaversion under utveckling). I FEM Design 11 modelleras jorden med fjädrar som ges egenskaper motsvarande bäddmoduler, vilka inte på ett helt rättvisande sätt kan spegla jordens komplexa respons vid belastning. Fjädrar kan t.ex. inte överföra skjuvkrafter mellan varandra, vilket får till följd att de enskilda fjädrarnas respons vid belastning är oberoende av varandra. Vid analys av en byggnads sättningar, med ett datorprogram där endast fjädrar (bäddmoduler) används för att beskriva jordens deformationsegenskaper, kan således en helt korrekt bild över jordens verkliga beteende inte återspeglas. I FEM Design 12 kan jorden även modelleras med volymelement, vars egenskaper modelleras enligt kontinuumsmekanik.

A new project has developed at the Swedish University of Agricultural Sciences in Alnarp during the spring of 2006. The garden design students has, during the course Interior Garden Design designed and built an construction with a new range of plants for Swedish conservatories. The plants are mainly from the cool temperate areas, instead of the tropical which often are the most common in public spaces. This means, among other things, that the cost for warming is very low. The working process and the construction carried on as workshops in the conservatory at Trädgårdslaboratoriet in Alnarp. During a few weeks the hole construction is completed.

Radio frequency identification (RFID) is a versatile wireless technology usedworldwide. The fields of applications are many and its popularity constantlygrows due to smaller in size, better and less expensive components. RFID isused to identify, track or share information about an object using radio waves.This master thesis describes the process of designing and implementing ahandheld UHF RFID reader. The goal was to, based on a UHF RFID-chipdesign a fully functional, small in size and power efficient device. Amicrocontroller provides the user interface and is also used to control theRFID-chip and a Bluetooth device.

Marknaden för smartphones har vuxit stort under de senaste åren och även utveckling av applikationer till dessa. Då utveckling av applikationer för smartphones skiljer sig från traditionell utveckling så passar inte traditionella utvecklingsprocesser för utveckling till smartphones på ett optimalt sätt. Denna studie undersöker mobilapplikationsutveckling med fokus på användbarhet. Då det råder brist på systemutvecklingsprocesser för mobilapplikationsutveckling så vill denna studie utvärdera ISO standarden ?ISO 9241-210 ? Användarcentrerad design för interaktiva system?.

Package design constitutes an important marketing and differentiation tool in an increasingly competitive food market, particularly in the category of daily consumer goods where the turnover rate is high and the purchases are based on self-service (Hine, 1997; Spethmann, 1994; Underwood, 1999). Media fragmentation undermines the traditional marketing tools and the demands for packaging are bigger than ever. A package must not only sell a product, but also tell, through design, how the product is used and express the values that the trademark owner wishes to convey to the end customer (Underwood, 1998). The understanding of the role of packaging as a marketing tool has increased, but the initiators inside the packaging industry in Sweden still think that the Swedish packaging industry is developing slowly. They often describe Swedish packages as homogeneous and unimaginative.

The project was carried out with SwedSafe AB, engaged in hearing and manufacture of earplugs. Since the company is a world leader in the sale of these products, it is important that they keep a higher level of quality of these products.Production of earplugs is currently a automated manufacturing process that is divided into four conveyor belts and one of the conveyor belts is what will be affected in the project. The belt affected during this process is exposed to various elements such as filling, closing, fermentation and extraction of products. Because the belt gets dirty, degraded products and the work environment is affected. To increase the quality of products and improve the working environment requires an automatic cleaning process, which collects dirt from the belt.The aim of the project is to design a machine that prevents the belt from becoming dirty, preserve molds clean and improve the working environment without disrupting production.

In motorsports competition, safety reasons require that the vehicle is equipped with some form of protective roll cage. The roll cage should withstand the forces involved in a collision to protect the driver and the co-driver from the vehicle body deformation. The roll cage also works to protect the vehicle from excessive deformations to more easily make any repairs afterwards. For the roll cage to be certified and approved for motorsports competition, it requires that the cage is built after one of the recommended options. One of those options is to design the roll cage like a cross-construction at the driver and co-driver doors.

The Swedish Armed Force is one of the largest authorities in Sweden and has as its primary mission to be responsible for Sweden's military defence. Their unique activity - to participate in armed combat ? requires leaders who can make quick and rational decisions in uncertain and conflicted environments. This study aims to gain an understanding of how individuals with leadership roles in the Swedish Armed Forces are experiencing their leadership in relation to the organization's structure and culture. In order to achieve the purpose of the study, the following research question was created: How do individuals with leadership roles experience the influences of the organization's structure and culture on their formal leadership? The theoretical starting point is Weber's organization theory, Schein's organizational culture theory, and different definitions of leadership.

Detta examensarbete beskriver processen för framtagandet av en ny design för det befintliga schemaläggningssystemet för räddningstjänsten. Ett av problemen med att schemalägga för personalen inom räddningstjänsten är att det är flera faktorer som måste tas hänsyn till. Några av dessa faktorer är vilken station de arbetar på, personalens kompetens, att det ska finnas personal på stationerna och arbetsroller. Syftet med examensarbetet var att skapa en ny design som uppskattas av de som arbetar med systemet. För att uppnå detta var de som schemalägger med och påverkade designen av systemet tidigt i designprocessen.Detta examensarbete innefattar en litteraturstudie, en förstudie, en intervjustudie, en fokusgrupp och två användartester.

This is a thesis about design of young stands of trees. A big source of inspiration has been Västerskog and Tor Nitzelius Park in Alnarp which both consists of a structure of squares. I wanted to examine if this type of planting could be valuable from an aesthetic and recreational point of view. One problem today is that many people believe that we have to wait for decades for a planting to grow up so that we can enjoy the ?ready result?.

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.
