The scope of this master´s thesis is the issue of usability in relation to interface design,in particular the interface of a university library´s online public accessed catalogue, orOPAC. Since the OPAC can be seen as the library´s ?shop window? to the world, it isof great importance that the interface to the OPAC can be used by patrons witheffectiveness, efficiency and satisfaction.The master´s thesis is based on a qualitative study performed at Karolinska InstitutetsUniversity library, and contains both a usability evaluation and an interview study. Twointerfaces were evaluated: a standard web interface provided by the system supplier, andan interface developed in-house by Karolinska Institutet´s systems department. The twointerfaces are both connected to the same online library catalogue, thus making possiblea comparative study..

In order to counteract and to discover unethical actions within an organisation, a growing number of Swedish companies implement a so-called whistleblowing system. The purpose of our essay is to study the mindset of companies and further analyse how this mindset affects the design and quality of companies' whistleblowing systems. To do this, we have used a qualitative approach by interviewing different Swedish companies about their mindsets and systems. The study determines that there seemingly are three different categories of systems of varying quality. In this study we have chosen to call them "internal system", "external system" and "combined system".

Nowadays, a lot of resources are spent on developing systems that will make it possible forvehicles to act autonomously, and make them more effective. One of the projects that isworking on this is the Gulliver Project. Gulliver has constructed a number of miniaturevehicles equipped with various sensors, to use as a physical testbed for autonomousdriving. One big disadvantage with this method is the long iteration time that occursduring the development and testing of a new software.This project has improved this process by developing a system architecture of a virtualtestbed where it is possible to simulate autonomus vehicles that communicates throughany type of wireless network. The testbed has made it possible to simulate autonomusvehicle systems that with a reasonable margin of error, acts like the system would actin a physical test.

Wastewater handling of private sewage systems has become an all increasing matter. In Stockholm region the 90 000 private sewage systems contribute with larger phosphorus flows to the Baltic Sea than the two biggest sewage plants in the area, Henriksdal and Käppala, contribute together, even though these two plants purify wastewater from more than one million inhabitants. When summer house areas turn into areas for permanent living ? transition areas ? the load on the existing systems increases, systems that already often are unsatisfying. In those areas it is not clear what the best system choice is; On-site systems for single households; Local collective systems or Connection to central systems.

The aim of this Master's thesis is to compare the 6th and the 7th editions of the classification scheme of the Swedish classification system (SAB) to reveal which principles are used concerning the development of this system during the period 1985-1997. Guiding questions are: What kind of changes has been conducted? How do these changes relate to development of other general classification schemes and to theories concerning revision work? The results of the analysis show that possibilities to use synthesis have increased by an extension of use of geographic and chronological subdivisions. The classification scheme has also been easier to use by elimination of parallel subdivisions and regularization of the scheme. To maintain stability revision is performed on selected subclasses.

Detta examensarbete är den avslutande delen av utbildningen inom maskinteknik på Linnéuniversitetet i Växjö under våren 2013. Arbetet utfördes i samarbete med Rottne Industri AB där skogsmaskiner utvecklas och tillverkas för skogsbruk. Projektet innefattar utveckling av en hjulupphängningskomponent kallad ?hjularm? tillhörande företagets ledande produkt, skördaren H-8. Resultatet slutade i en ny design av hjularmen med hjälp av CAD-modellering, Systems Engineering och FEM-analysering..

For many decades the increase in traffic volume, expansion of highways and infrastructure has lead to an increase of wildlife vehicle collisions which are unfortunately very common in many countries today. They cause great deal of material damage and even kill humans or wildlife. Measures in the form of warning signs, under- and overpasses and fencing have been implemented for a long time with the help of observation by hunters and collisions sites. However this study focuses on the moose?s perspective and the variables that, both spatially and temporally, could have an effect on why and when moose are close to certain types of roads.

The aim of this thesis is to examine one part of Amazon.coms recommender systems: Similar Items. The purpose is also to show the difficulties with subject access, i. e. to find a similar book to the one you just read; problems with traditional systems versus the usefulness with recommender systems like Amazon.coms Similar Items. Similar Items presents a set, a cluster of related items to a given item based on customers co-purchase.

Earlier studies of musculoskeletal problems with milkers working in milking parlour operators have shown that it is a physically demanding occupation. The extremities that are most exposed are neck, shoulders, hands and wrists. Those systems that have been studied in present cases are fishbone and some tandem barns. There have been changes in the working environment during the past ten years. The mechanisation has been developed for the better with automatically removers of the milking units and vertically adjustable floors in almost every daily milking barn. In other hand the milk production are more industrialised and more related to stress today.

I en konkurrenskraftig omvärld, finns det ett behov hos företag av väl integrerade informationssystem. Systemen har till uppgift att se till att aktuell information i verksamheten kommer alla till godo när personalen har behov av den. Idag har företag standardiserade affärssystem till sin hjälp för att hantera den information de har behov av i sin verksamhet. Studien har haft som syfte att beskriva hur anskaffningsprocessen kan se ut på olika företag och att besvara följande frågor:·       På vilka grunder togs beslutet om införskaffande av ett nytt affärssystem?·       Har ledningen varit involverad i anskaffningsprocessen?·       Ledde implementeringen till ett system företaget blev nöjda med?Studien har gjorts med en kvalitativ ansats, där halvstrukturerade intervjuer användes för att samla in empiri.

VSEM project and the need for a more efficient way of handling requirements andinformation are highly apparent.The overall objective of this thesis is divided into two parts:1. To identify criteria/factors leading to a successful introduction of an informationmanagement system.2. To develop an implementation process for a requirement management system ?the first step towards a PLM system in EE development at VCC.This will be done through interviews with employees, a literature review and an analysisof studies of three earlier projects within VCC.The conclusion of this study shows the great need for change in work methods fordesigners handling information and requirements. An implementation process has beenidentified with guidelines on how to handle different phases of the process.

There exist several known methods for calculation of radio coverage for ground-based systems. As far as we know there are no equivalent methods for the case of flying platforms when the altitudes and speeds are significantly different to those of ground-based systems. This thesis describes the theoretical concepts behind calculations of radio coverage for flying platforms. An investigation is made to sort out what is important and possible to employ in a model for simulations. A method is described and implemented in a program for evaluation of flying radio systems.

Abstract PurposeThis thesis aims to focus on how master students administer scholarly articles after they have found them. The purpose of the study is to detect how and to what extent people administer their articles from a personal information management-perspective (PIM).MethodTo answer the research questions, a web-based questionnaire survey was distributed which was announced to around 2,000 master students from different universities in Sweden. Most of the items in the survey focused on individual storage methods. The respondents were asked to rate the frequency of their different information administration behaviors on a seven level Likert-type-scale. Subsequently, items concerning specific information administration behaviors were posed, followed by questions on the respondent's sociodemographic status.

The domain of this thesis is Personal Information Management (PIM) which is a sub-domain to human-computer interaction (HCI) that specifically concerns the interaction between human and information. The purpose of the study is to make an exploration of information management in a scientific research setting, to study which tools and strategies for information interaction that are used in the context and to suggest possible improvements of today's practices. Three in-depth interviews with scientific researchers have been conducted followed by a qualitative analysis of the results. The results show that there are great variations among the three respondents and that there can be distinguished as much as 15 different dimensions that when put together forms a unique PIM profile for each individual. The recommendation following this is that tools for PIM have to allow a high degree of individualisation.

The main aim in this Master thesis is to analyse how an ideological view may have influenced the shape of hierarchies with a specific concentration on the concept of fiction genre in the latest versions of the systems SAB and DDC. Our thesis is that no theoretical classification scheme can be recognized as objective. With an ideological/institutional perspective we look at the structures behind these systems. As a vehicle we use the hermeneutic circle to show the play between part and unit by focusing and analysing three different levels: the content level the concept level the ideological level. The first level is in the shape of a historical background and an analysis of concept with focus on content.
