With climate change, the temperature and relative humidity in Sweden are increasing. The majority of historical environments lack protection against this increase, which also increases the risk of mold infestation in these environments. One of these environments is N??s Slott, in which several rooms have recurring mold growth on objects and furniture. By examining one of the rooms in the castle that is in the risk zone or has mold growth, factors behind the mold growth can be investigated in order to create a basis for future actions against mold.

The aim of this thesis is to describe and evaluate the usability of two Swedish systems, Sofie and Carlotta, which are used to organize and present data regarding museum objects on the web. This thesis also presents how objects are described and made accessible to the public in the two systems. To evaluate the usability, a heuristic method combined with Systematic Usability Evaluation has been used. The description and accessibility of object representations in the systems are evaluated using indexing and classification theories from the field of Library and Information Science. Additional theoretical background that has been used is how users search and browse information systems.

With the growth of information stored over Internet, especially in the biological field, and with discoveries being made daily in this domain, scientists are faced with an overwhelming amount of articles. Reading all published articles is a tedious and time-consuming process. Therefore a way to summarise the information in the articles is needed. A solution is the derivation of an ontology representing the knowledge enclosed in the set of articles and allowing to browse through them. In this thesis we present the tool Ontolo, which allows to build an initial ontology of a domain by inserting a set of articles related to that domain in the system.

Problemet med hantering av fel vid informationsutbyte mellan system hos stora företag med komplex IT-arkitektur är bakgrunden till varför denna rapport har skrivits. Det primära företaget i denna studie har varit Sandvik AB.Typiska fel som kan uppstå i sådana sammanhang är så kallade logiska fel. Definitionen av ett logiskt fel är ett fel som påverkar processens funktionalitet vid utbyte av information mellan två eller flera system. Exempel på sådana fel är att ett visst system behöver en viss speciell information eller har vissa regler uppsatta för att kunna ta emot information från ett annat system. När det hänvisas till tekniska fel, så avses fel som kan uppstå i den tekniska infrastukturen.Problemet med logiska fel finner man mest i distribuerade system och i SOA-arkitektur där det finns en anledning till detta på grund av dess uppbyggnad och lösa kopplingar mellan system.

The Thesis purpose is in the context of system development validate the Scrum Methodology. Projects concerning information technology are difficult to manage and tend to fail in quality, time or costs. Scrum presents a new view of the system development. Better cooperation between customers and developers, continuous follow-up on daily basis and extensive communication in the development team are all characteristics of Scrum. Scrum is described as a new paradigm by its founders but has been criticized by experts of system development too.

The main purpose of this study is to investigate the productivity effects of multiple tree handling in thinnings. Other important elements have been to investigate in which extent multi-tree handling is used in stands with different stem volumes and the impact of collecting partially delimbed fuelwood assortments has on harvesting performance. The study is based on data from thinnings in Sydved and contractors' operating activities. Collection and compilation of operating schedules, number of stems and surveyed volumes from several contractors and a large number of executed orders underlying the results. Multiple tree handling is used to a much greater extent at lower average stem volumes. Prediction models for productivity of the multiple-tree handling harvesters in the study differ from the productivity models for single-tree handling. In the model developed in this study productivity is not as dependent of stem volume as reference models.

Books and reading are important elements in cultural policy. On 1 January 2002 VAT on books and magazines was reduced from 25 per cent to 6 per cent. The purpose was to increase reading in all sections of the population. A special Book Price Commission was appointed to follow and examine price trends and to work for an enhancement of reading in all groups of the Swedish population. But what form of reading are the BPC talking about? With a theoretical point of departure in the theory of power and discourse by Michel Foucault the aim of this thesis is to explore if there is an existing discourse about reading and, if so, how this discourse is operating in the BPC reports.

It is important that companies knows how to handle a complaint when they receive one from a customer. This information could the company take care of and use when they develop new services. Furthermore a good complain handling leads to satisfied and loyal customers which increases the revenue for the company. We have examined how SAS handle their internal information process and if this process affects the information and in that case how. The study is performed with a qualitative method, based on deep interviews.

This is a thesis project in the field of information technology which begins by evaluating existing food price comparison systems and subsequently aims to design an improved, web based system for said purpose. The system features interfaces for price reporting, price comparisons as well as various search and review functions. The objective is to create a system able to compete with existing price comparison systems, which requires careful selection of products that can be found in all foodstores that also represent different households; a user-friendly price reporting and price comparison interface and an efficient tool for ensuring the validity of reported prices.The designed system features a more accurate formula for calculating average prices in events where the real price is missing; a more reliable security mechanism forv alidation of reported prices and a more comprehensible interface for viewing price reports, reporting prices, reviewing stores and products in comparison with existing systems. The system does, however, suffer from some optimization issues primarily in the form of inefficient database modeling; SQL queries and JavaScript code although testing has shown that these shortcomings do not hamper overall performance to such a degree that usability is compromised. Further usability testing performed on the system with five test subjects shows that a high level of overall user-friendliness has been achieved even though some special features, such as the detailed report containing price information per product for each store need to be improved.It is not possible to say at this time whether or not the designed system will be able to compete with existing ones or if the very concept of food price comparisons per se is viable in terms of profitability and marketability.

This thesis in Art History and Visual Science is about values to graffiti and graffiti artist Banksy. I have studied values relating to Banksy´s graffiti images through which context they are placed in and where they are located. I have selected two different images of Banksy as an example on the basis of a transnational phenomenon, where the images that circulate in the public arena by street art and other images and imported into the galleries and consumption market. My conclusion is that the values of the images are based on the context in which each room have its surroundings and that therefore the impression will increase. The public space context, signal availability and the white cube context indicates art, and the commercial context signals goods and items that can be bought.

För ett par år sedan tog utvecklingen och fokuseringen kring Internet fart på allvar ute bland företag. Alla skulle ha en webbsida och anledningen till detta var ofta att konkurrenten hade en eller att man bara ville synas. Idag finns det ett antal så kallade Content Management System utvecklade för att hantera information på Internet, intranet och extranet. Det gemensamma för dessa system är att användarna skall kunna uppdatera, vidareutveckla och administrera lösningen utan någon teknisk kompetens. Syftet med den här uppsatsen var att undersöka om ett Content Management System effektiviserar uppdateringen av information, med hjälp av kategorier inom användbarhet.

Customer information is to be seen as an essential part in service development. The company should be aware of how their customers experience their services. The company can get access to customer information through complaints from their customers. All information obtained from the customers is not possible to use when developing new and existing services. The information has to be analysed before it is possible to use it for service development.This paper describes if Scandinavian Airlines (SAS) uses their customers as a source of knowledge when developing new and existing services and in that case how.

In printed text, sound is a somewhat forgotten aspect. The recitation of text is vital in areas like poetry and oratory, but still has no distinct technique of being communicated. Emphasis of a word might be expressed through italics, but no canonic character set or system for vocal delivery of texts exists. With this essay we are creating a foundation for a development of such a character set or system. By studying existing visualisations of sound and comparing these with semiotic and perception-based theories we obtain useful insights for a prospective system for visualisations of vocal sounds.We conclude that the aspects of sound one wants to visualise must be carefully defined since the viewer cannot process infinite amounts of information.

Human-computer interaction is central for computer assisted development. The aim was to investigate the user experience of a new (U2) compared to an old (U1) computer system, within a cognitive psychology frame of reference. Six subjects, frequently using the system, participated in the study. It was shown that the new (U2) compared to the old system (U1) enhanced and supported more the users? system related procedures/tasks.

Den långsiktiga bevaringen av digital information innebär nya utmaningar för svenska offentliga arkiv. I arbetet med att utveckla system för att hantera dessa utmaningar utgår svenska offentliga arkiv ifrån en konceptuell rammodell kallad Open Archival Information System (OAIS- modellen). Syftet med denna uppsats är att bidra med en ökad förståelse för hur svenska offentliga arkiv kan hantera de aktiviteter som ryms under bevarandeplanering (Preservation Planning) enligt OAIS-modellen. För att uppnå syftet har existerande forskning på området granskats och kopplats till bevarandeplanering enligt OAIS-modellen. För att kunna utvärdera den existerande forskningen har ny empirisk data samlats in genom kvalitativa intervjuer.
