Interactive Visualization of Statistical Data using Multidimensional Scaling Techniques

This study has been carried out in cooperation with Unilever and partly with the EC founded project, Smartdoc IST-2000-28137. In areas of statistics and image processing, both the amount of data and the dimensions are increasing rapidly and an interactive visualization tool that lets the user perform real-time analysis can save valuable time. Real-time cropping and drill-down considerably facilitate the analysis process and yield more accurate decisions. In the Smartdoc project, there has been a request for a component used for smart filtering in multidimensional data sets. As the Smartdoc project aims to develop smart, interactive components to be used on low-end systems, the implementation of the self-organizing map algorithm proposes which dimensions to visualize.

The questionnaire consisted of ten questions with a Visual Analogue Scale as a main question. Questions about age, gender and dental anxiety were also included.

Fällning av kisel från avloppsvatten vid Hellisheidarvirkjun - experimentell studie

This report is about the experiments with mixing of the separated water and the vacuum pump seal water at Hellisheiði power plant. This is done to prevent silica scaling and clogging in pipes and reinjection wells as well as eliminating vacuum pump seal water from the plant. The experiments were done in four stages: the first stage comprised of tests with different flows of separated water at 70°C, the second stage was carried out by mixing the separated water at 70°C and the seal water with different amounts of the seal water, the third and the fourth stages were like the first and second but with the separated water at 120°C. The results show that this method is good if the mixture is around 50/50 separated water and seal water, to control the silica scaling in the separated water and to be able to reinject the seal water with the separated water. This does not eliminate the silica scaling in all of the separated water because the amount of separated water is much more than the amount of seal water that comes from the plant. .

Matematik, ett tråkigt ämne! Kan laborativt/praktiskt arbetssätt ändra elevers attityder till matematik?

The aim of the study was to investigate the students´ attitudes towards mathematics, their knowledge in the subject area they find the least interesting and whether laborative/practical working methods could awaken their interest and curiosity. During our work, we have looked into previous studies regarding girls´ and boys´ attitude and performance in mathematics. We handed out surveys to students in grade 9 at a School with many people from other cultures and nationalities in Malmö in order to find the answers to our questions. The result showed that most of the students thought that the subject area "scaling" was the least interesting. The implemented action program was a laborative/practical task within the "scaling" area.

Frekvens och spanningsskalning i en inbyggd mikroprocessor; for att mojliggora implementationen av schemalaggning med stod for dynamisk frekvens- och spanningsreglering for energihantering.

Minimizing power consumption is a critical part of many embedded design projects. Thechallenge is to limit the power consumption of the system and at the same time providesatisfactory service to the user. With regards to microprocessors, the main way of limiting powerconsumption during program execution is to adjust the frequency and the voltage at which theprocessor operates.To enable the implementation of real-time scheduling with support for dynamic voltage andfrequency scaling, an exhaustive study of the Freescale i.MX31 embedded microprocessor isperformed. Specifically, the power consumption relationship to all relevant frequency andvoltage settings is investigated. In addition, to enable frequency and voltage scaling in a real-timeenvironment, a complete timing analysis of proposed voltage and frequency scaling methods isperformed and their suitability for use in real-time systems is evaluated.To integrate voltage and frequency scaling capability into OSE RTOS, a software module hasbeen developed for this operating system.

Användarorienterad förarsituation för bergavläsning vid fjärrstyrt skrotningsarbete

Mechanical scaling is one of the most complex operations of all in the mining process. The operators are using both hearing, sight and feel to read the rock and to know where to scale and where to leave. They say they go on gut feeling in great extent, something that comes with experience. The scaling machine is placed into the edge of unsecured and newly blasted rock to hammer off the blocks that has become loose after the blast, but not enough to fall down. It goes without sayingthat it is a risky job.

European Union Politics ? en tidskrift och dess invisible college

Author Cocitation Analysis (ACA), Multidimensional scaling (MDS) and Social Network Analysis (SNA), has been used to analyze and visualize the invisible college of the journal European Union Politics. The concept invisible college was first introduced in the fifteenth century, through the creation of the ?the Royal Society of London?, and it was reintroduced in the 1960:ies and the 1970:ies by scholars such as Price and Crane. It is said to have been interpreted in as many ways as there are authors who have used it. Here it has been used synonymously with the term citation network.

Klinisk utvärdering av lokal antibiotikabehandling hos rökare i ett parodontalt stödbehandlingsprogram -en pilotstudie

Syfte: Syftet med den här pilotstudien är att undersöka om lokal antibiotikagel, 8,8 % doxycyklin, som tilläggsbehandling kan förbättra läkningen av inflammerade tandköttsfickor hos vuxna rökande patienter under stödbehandling. Material och metod: I den här dubbel-blinda randomiserade kontrollerade pilotstudien valdes 20 vuxna rökande patienter ut från ett parodontalt stödbehandlingsprogram. Patienterna indelades i två grupper, 10 i testgruppen (doxycyklingel 8,8 %) och 10 i kontrollgruppen (placebogel). Vid baseline och tre månader efter behandling utfördes parodontal klinisk registrering. Patienterna fick behandling med scaling och debridering i hela bettet, testgruppen fick applicering av doxycyklingel vid testtänder (PPD ? 5 millimeter, BOP) och kontrollgruppen fick placebogel applicerad vid kontrolltänder (PPD ? 5 millimeter, BOP).

Forskningsområdet biblioteks- och informationsvetenskap vid Högskolan i Borås ? En bibliometrisk studie av den intellektuella basen 2001?2006

The aim of this study was to map the intellectual base at the Swedish School of Library and Information Science (SSLIS) at the University Collage of Borås, and to compare this intellectual base to the intellectual base of the research area Library and Information Science. This was done by analysing the citations in publications published, between the year of 2001 to the first quarter of 2006, by researchers at the institution, using the technique of author cocitation analysis. Cluster analysis and Multidimensional scaling, statistical techniques that are traditional i the author cocitation analysis, formed an objective map of the intellectual base at the SSLIS. This map was then compared with three prior studies, that used the same technique to map the intellectual base of the research area. The result shows that the map of the intellectual base at the SSLIS consists of the specialities: user studies, library studies, culture/cultural policy, information retrieval, bibliometrics and information in organisations.

FATTIGDOMENS FEMININA ANSIKTE : ? En studie om fattigdom ur ett genusperspektiv

The estimated number of people living in extreme poverty is 1.3 billion and 70% of those are women. The aim of this study is to explain in what ways and why women are regarded as poorer than men.The definition of poverty has expanded and is now multidimensional. In order to answer the aim of this thesis the following dimensions will be included and work as a theory in which the analysis will be structured after. Through a gender perspective, will the role of woman emerge through a multidimensional definition of poverty. If the balance is a negative in these dimensions, the situation for women will worsen and become permanent.

Tjänligt vatten i kranen - Membranteknik gör det möjligt : En utredning av pilotförsök i Glemmingebro

Nanofiltration is a proper way of preparation of drinking water. The process has a lot in common with reverse osmosis where a semipermeable membrane is used to separate a pure water flow from the remaining water. A pilot plant was used to ensure that nanofiltration is a suitable technology for a specific waterworks station in Glemmingebro, Ystad. The purpose was also to find out if a pH-adjustment is needed for feed water in a possible full scale plant.  In this case nanofiltration is used mainly to remove sulphate and calcium since the raw water contains concentrations of these substances which exceed the limits for potable water. It is important to receive a high recovery (RC), otherwise the deliviery of water won?t be high enough.

Multilateral och unilateral säkerhetspolitisk praktik och strategi för hantering av Syrienkonflikten

This security study attempts to explain the dynamics of international conflict management of an intrastate conflict, through a combination of three theoretical frameworks. The conflict in Syria is shown to be managed mainly through strategies using coercive diplomacy, and some main contributions within the research field relating to strategies of coercion are used for guidance, to important factors which could affect coercive international conflict management, as well as to additional theories which could enhance the study?s explanatory power through a combined theoretical framework. The two added theoretical frameworks are Power Balancing and a Multidimensional concept of Power. With the aid of analytical tools derived from this combined framework the conflict management is analysed within both a multilateral and unilateral setting, offering some explanation as to why international conflict management (practiced by UNSC multilaterally and USA unilaterally) has shown so little progress in regard to the conflict, as well as why one significant, though limited, result could be achieved regarding the destruction of the Syrian regime?s chemical weapons arsenal..
