I både kvalitets- och kontrollarbete finns det behov att kunskapsmässigt komma så nära verkligheten som möjligt vid fastställande av defektparametrar för oförstörande provning (OFP). Orsaken är att olika acceptanskrav och bedömningsgränser är svåra att klarlägga när man inte kan förlita sig på att uppgifter är realistiska. I projektet har olika erfarenheter använts för att få en bättre helhetsbild i området för defektparametrar och oförstörande provning.Denna rapport redovisar den inledande delen av forskning och utvecklingsprojektet PLANT 2, där olika defektparametrar kartlagts och en teoretisk bedömning utförts med avseende på hur signalsvaret påverkas för OFP-metoderna virvelström (ET) och ultraljudsprovning (UT) i form av puls-eko (PE) och ?time-of-flight-diffraction? (TOFD).Definitionen av redovisade defektparametrar följer i stort SKI-rapport 95:70 [1]. Defektparametrar i denna rapport redovisas i bilaga 1.Vid bedömningen av defektparametrarnas inverkan på OFP-tekniker, har drift¬inducerande defekter och tillverkningsdefekter hanterats separat.

Användbarhet är idag en del av människa-dator interaktion som bl.a. Södertörns högskola satsar på att lära ut. Syftet med denna undersökning är att belysa användbarheten på Södertörns högskolas hemsida. För att definiera användbarhet används den internationella standarden för användbarhet (ISO 9241-11, 1998) samt människa-dator interaktionsforskaren Jacob Nielsens definition av användbarhet. Detta har genomförts genom en observationsstudie med fem användare.

Our aim in this work has been to redesign ModernFamilies and make a user-friendly interface for people with aphasia. The focus has been to identify general issues they might face while using different technology and applications, in order to find better alternative design for ModernFamilies, with a focus on usability. To approach this issue, we used a qualitative method. Our study includes several interviews and observations preformed in conjunction with the AGNES project (AGeing in a NEtworked Society) and speech therapists. Aphasia requires simple design that in the same time gives them support to understand and use technology and different applications.

This thesis describes how the chip space and coolant channels are designed in today?s mills, the ideas behind the design and what is considered to be the best method of cooling. It contains ideas on how the chip space can be simplified. It contains several concepts on how the cooling could be designed for better efficiency and manufacturability. There are also suggestions on how the cooling could be stopped when the cutter isn?t cutting.

Involving prospective users in a development process is important. This makes it easier to make a more usable product. This thesis is about developing an intranet targeting a school and focus is aimed towards intranet usability.The reader is given knowledge into how to design and implement an intranet using persona. Design and develop by using persona is difficult when there is a group with large variety of knowledge, age and technology interest, so as in this case. Persona although always helps during the development phase because of the strong links to the personas that are created, which gives developers a constant reminder of the end users of the system.The thesis describes how information is collected and processed.

This report presents the redesign of the online-based non-governmental organization Equalisters? (Rättviseförmedlingen in Swedish) website. It aims to achieve an understanding of how you take into account the user and other stakeholders and their interests when developing a website. The focus was on redesigning an existing website and prioritize the different stakeholders? needs.

This report is about finding the cooperative elements in games and making a boardgame based on them. I tested different computer games and boardgames to try and get the cooperative elements and then I make a boardgame based on what I found.What I found during testing is that to be a fully cooperative game all players on the same team must win or lose together and one player should not be able to finish the game by herself. There are of course some things that can change this for example what kind of players are playing.My best advice is that you should decide that the game is fully cooperative from the beginning and build the game from that..

Due to increasing product availability and higher demands on fast deliveries, the competition between companies is growing. To be able to satisfy the customers? requests an efficient logistics system with short throughput time is required. By using tools associated with Lean production companies are able to make great improvements in their manufacturing systems and reduce lead times to satisfy customer demands.There are two classifications associated with manufacturing, high variety and low volume (HVLV) and low volume and high variety (LVHV). The general belief is that the concept of Lean production is difficult to implement in a production environment with high variety and low volume due to the concept being adapted to mass production.

When performing studies that test the reactions of horses in different situations, important information may be available about the horse?s reactivity level. With information from these tests, accidents and dangerous situations may be prevented. When the behaviours from tests are compared with race performance it may be possible to evaluate if some behaviours are more desirable at the race track than others. The aim of this study was to see if behavioural responses correlated with physiological parameters (heart rate, cortisol), the trainer?s opinions and actual race performance.

Various electromagnetic (EM) treatments has been investigated for their potential in improving crop productivity over the past century. There is today an increasing amount of scientists advocating EM treatments as an organically compatible method for improving plant growth and yield. However, failure to produce repeatable effects and defining causal mechanisms has made it a study of much controversy and debate. The subject requires indepth interdisciplinary knowledge, making it inaccessible for the majority of biologists, horticulturists and growers. In this combined literature review and pilot study, these issues are addressed by providing a comprehensive introductory review of the topic plant bioelectromagnetics and its potential horticultural usability.

Android is one of the leading software platforms for the new generation of smartphones. The market for applications is growing rapidly. So to be able to compete with such large competition the applications need a solid and stable development methodology. Therefore have we created an application based on a test-driven development, to investigate if the methodology was applicable on the Android platform. The conclusion is that Android?s suitability for test-driven development is dependent on the application that is being developed and if difficulties concerning the testing framework can be avoided.

It is in society's interest that news is conveyed in a correct and memorable manner. News contributes to general knowledge and increases awareness of other people's life situations. Because of news the population is able to follow and be a part of the political debate. Therefore, it is important that one remembers what one has seen, both in long and in short term, i.e. memorability is a critical aspect when it comes to news.The aim of this work was to study the news form a memorability perspective, that is, how long one remembers the news after watching them.

This report describes the initial work intended for updating the car sharing service Roadmate. Roadmate is one of the services received by the car rental company Hertz First Rent a Car. The goal was to present the client with design- and structure proposals for a car sharing service that includes high usability and at the same time remains aesthetically pleasing.The work is based on an initial study with data collection, mapping the target user group and its needs. Subsequent structural and design proposals for Roadmates company carpooling service are based on the facts surrounding the target group's needs. The result are well developed and tested design sketches with accompanying visual identity and sitemaps that can be the basis for the further work on the development of the service..

Randomness is a complex area of computer science, where only pseudo random numbers are possible to generate algorithmically.This report presents established algorithms for random number generation by conducting a basic study of relevant literature, while testing distribution and speed of the algorithms contained within the C++11 Random library. The results are compared to the algorithm XORShift and a modified version of it. The study shows that the modified algorithm passes all tests in Small Crush, andthat the run time is shorter than for those in the Random library. The conclusion is that it is possible to, with simple means, modify an algorithm to outperform the algorithms of the C++11 Random library..
