PARAMETRISERAD DESIGN APPLICERAD PÅ EN MOTORSÅGSKEDJA

The main objective of this thesis was to develop appropriate strategies and find factors that affect the usability of parameterized designs. This was accomplished by investigate the user-interface and how it is designed to meet the user's information needs. The thesis also embraces the basic theories in terms of investigation, cognitive design principles and human behavior patterns in the interaction with the machine. The approach has led to an explorative investigation in this subject area.The thesis also had the purpose to achieve more efficient ways for development of motor chainsaws at Husqvarna AB's department Global Cutting Equipment. That can be achieved through reduce costs of development per sold unit.

Users of the product value comfort, flexibility, softness, comfort and a discreet product. Users are for individuals with incontinence problems that usually receive the products via prescription. The product must also have an attractive price and good quality from the purchase / originator's perspective.Currently there are two models that Attends supplies, which the project intends to develop, (Slips / Briefs and Pull On's).

Kan Lamotrigin utgöra ett Behandlingsalternativ vid Bipolär Sjukdom?

Bipolar disorder is a severe, affective illness which causes a person to alternate between episodes of pathologically elevated mood (mania) and depression ? in between these episodes the mood is normal. The length and intervals between the episodes are highly variable among the ill, as are the severity which is divided into two major subgroups: bipolar I and II. Bipolar I disorder is the most severe because of the patient?s inability to realize that he or she is currently in a manic phase, in the case of bipolar II disorder, the patient is aware that he or she has an abnormally raised mood, a state which is called hypomanic state instead of manic.

Tjänsteorienterad arkitektur : Ett arkiv- och informationsvetenskapligt perspektiv på tjänsteorienterad arkitektur

The starting point of this paper has to do with rapid changes within the information technology and the need for agile and fast systems. The primary goal is to investigate what happens with recordkeeping practices in agile environments like service oriented architecture (SOA). It is in the possible transfer between IT architecture and digital archive the area of this paper resides. The paper relates to the Records Continuum model by which records will be considered historical and active at the time of creation. In the Records Continuum model recordkeeping practices and archival requirements will have to be taken into account at the time of creation.This paper concerns SOA from the perspective of Archival and Information science.

A rest product from the metal process is particle-polluted gas and cyclone designs are today the most commonly used abatement device for particle control. A cyclone provides a simple design with high efficiency particle percolation by using air streams.The purpose of this work is to reduce the time it takes create new cyclone designs in Outotecs projects. An extensive construction work is needed for every new cyclone order due to new designs.

Användbarhetsutvärdering av en grafiskt visualiserad patientjournal

Förstaårsstudenter vid Linköpings Universitet har utvecklat en prototyp som på ett nytt sätt visualiserar en patientjournal grafiskt. Beställare av projektet var Institutionen för medicinsk teknik vid Linköpings Universitet som nu vill att en användbarhetsutvärdering genomförs av prototypen. Prototypen riktar sig till anställda inom sjukvården och ska användas på en liten handhållen enhet med pekskärm. Av denna anledning ska den vara ett komplement till befintliga system när användarna arbetar nära patienterna. Då den ännu befinner sig tidigt i utvecklingsstadiet är det nödvändigt att fortsatt utveckling sker i nära kontakt med användarna.Detta examensarbete syftade till att peka på vilka användbarhetsprinciper prototypen bryter mot, vilka behov den måste tillgodose, att undersöka hur användarna interagerar med en Ipod touch och vad de anser om att arbeta med en sådan enhet.

Stora bostadsfastigheter i glesbygd : En studie av rättsfall och praxis

För att främja landsbygdens utveckling och till följd av förändringar i markpolitiken tilläts genom lag bildandet av stora bostadsfastigheter på landsbygden 1990. Detta skulle ske genom att öka den enskildes möjlighet att utforma sin fastighet efter egna önskemål. Glesbygd, som är landsbygd karaktäriserad av gles befolkning, är mer utsatt för de problem som landsbygden står inför. Syftet med studien är att undersöka om det finns eller borde finnas en skillnad mellan lands- och glesbygden vid fastighetsbildning av stora bostadsfastigheter. Studien utförs genom en genomgång av rättskällor, tolkning av rättsfall och analys av Lantmäteriets praxis.

Hårdfräsning i verktygsstål : Förslitning av skäregg

This thesis work is made by Torbjörn Johansson on Karlstad University for Uddeholms AB. The assignment in this thesis work was to investigate tough cutting in three different tool steels: Vanadis 4 Extra, Vancron 40 and Sverker 21. The research was to compare the wear of the tool after cutting in each one of the tool steel alloys. The research was also made to see if the tool cutting in Vancron 40 has a better wear than the tool cutting in Vanadis 4 Extra and also compare the results with Sverker 21. All three of these alloys are a part of Uddeholms AB:s range of products, and is used in applications like forming tools and knife tools. Vancron 40 is a powder steel with a very good combination of mechanical properties like ductility, adhesive strength and hardness.

Undersökningsmetodik för klorerade lösningsmedel i marken

Chlorinated solvent are volatile organic substances that can be harmful for humans and for the environment. Examples of common chlorinated solvents are perchloroethene, PCE, and trichloroethene, TCE. Chlorinated solvents appear as contaminants in soils primarily where they have been used as washing fluids in dry-cleaning facilities or as degreasers in metal industries. Chlorinated solvents are DNAPLs (dense non-aqueous phase liquids), which means that they are not easily dissolved in water and that they sink to the bottom of the aquifer. Adsorption to soils is low so chlorinated solvents are mobile in soils.

Användbarhet för e-läromedel : anpassning för olika lärstilar

Vid utveckling av elektroniska läromedel är användbarhet en viktig faktor. Vad som är användbart är beroende av användarens behov och förutsättningar och läromedel har ofta en heterogen målgrupp. Målet med den här undersökningen har varit att besvara frågan hur e-läromedel kan användbarhetsanpassas för olika lärstilar. Undersökningen har genomförts med hjälp av litteraturstudier samt intervjuer med läromedelsförlag. Delar av Dunn & Dunns lärstilsmodell, specifikt sinnespreferens och informations­bearbetning, har relaterats till aktuella riktlinjer för användbarhet i e-läromedel.

Syntes och egenskapskarakterisering av volframoxid framställd med magnetronsputtring

The system tungsten-oxygen has potential of being suitable for decorative coatings since ceramic coatings are often hard and wear resistant, and since modulations in oxygen content or incorporation of small ions could give bright colours. The aim of this report was to investigate the relationship between process parameters and  the properties of the films, with the wear resistance being of special interest.Samples with tungsten to oxygen ratios in the range of 100:0 to 25:75 at% were made using reactive sputter deposition, either with constant gas flow, or gas flow controlled by optical emission of the plasma. The hysteresis of the system, which means that a certain gas flow will cause different pressure and/or target voltage depending on in what way the flow is reached, makes it interesting to control the process where the system makes the steep change from metallic tungsten to ceramic tungsten oxide. This is difficult and thus requires precise control equipment.The samples were analysed using X-ray diffraction, X-ray photoelectron spectroscopy and an empirical wear test suitable for small components like cell phone cover for example, in order to characterize the structure, composition and wear resistance of the coatings. The results could be divided into three groups: (I) tungsten-like, with very low oxygen content; (II) mixed phase and (III) tungsten oxide like, with oxygen content close to 75 at%.

Användbarhet och begränsad navigation i en interaktiv 3D-miljö : Inredningsverktyg för MIOs möbler

Det har blivit allt mer populärt på senare tid med inredning av hemmet, och det finns idag stora möjligheter med virtuell 3D, vilket gör projektet relevant för tiden vi lever i. Projektet handlar om att skapa en första prototyp av en möblerbar 3D-miljö med tillhörande användarvänligt gränssnitt som ska kunna användas i Mios varuhus. Prototypen bygger på två demofilmer av applikationen där gränssnittet och användarens interaktionsmöjligheter har visualiserats i en vanlig skärm, och 3D-miljön i en 3D-skärm, dessa har sedan synkats med varandra för att ge ett helhetsintryck av applikationen. Gränssnittet skulle vara så pass användarvänligt att Mios kunder själva skulle kunna använda applikationen och med hjälp av speciella 3D-skärmar och renderingstekniker skulle miljön framstå som verklig. Projektet startade med en förstudie, med intervjuer och research.

Managing Positions in a Dynamic Environment - New Technology Impact on Tactel and the Telecom Industry

The Telecom industry is facing a paradigm shift, where the industry is converging with Internet technologies and the market is becoming more sophisticated. This results in more demanding customers, and the need for offering more content and services with a focus on usability for the end-users. The operators are starting to loose both their strong position and revenue in the Telecom industry, due to new technology and the fact that other actors are starting to enter the market, offering new content and services. In the end, the operators have two choices, to become bit-pipe providers, and only focusing on network management, or keeping the control over their networks. The latter would mean that they block other actors who are taking parts of their revenue, e.g.
