ARAVQ som datareducerare för en klassificeringsuppgift inom datautvinning

Adaptive Resource Allocating Vector Quantizer (ARAVQ) är en teknik för datareducering för mobila robotar. Tekniken har visats framgångsrik i enkla miljöer och det har spekulerats i att den kan fungera som ett generellt datautvinningsverktyg för tidsserier. I rapporten presenteras experiment där ARAVQ används som datareducerare på en artificiell respektive en fysiologisk datamängd inom en datautvinningskontext. Dessa datamängder skiljer sig från tidigare robotikmiljöer i och med att de beskriver objekt med diffusa eller överlappande gränser i indatarymden. Varje datamängd klassificeras efter datareduceringen med hjälp av artificiella neuronnät.

Logikbaserade dokumentåtervinningsmodeller

The thesis deals with three document retrieval models based on logic: the Boolean model,the fuzzy model and the Van Rijsbergen model.In Chapter 1, the author presents the purpose of the thesis. This is to give the logical foundationof the models, to describe them and to examine them critically. In Chapter 2, some importantnotions in document retrieval are presented. Chapter 3 is devoted to the Boolean model, Chapter4 to the fuzzy model and Chapter 5 to the Van Rijsbergen model.These three chapters are organized in the same way. First, the logical foundation of the modelis given.

Space Syntax som analysverktyg vid cykeltrafikplanering

Cykeltrafiken har kommit att ta allt större plats i trafikpolitiska sammanhang och har numer ensjälvklar roll i utvecklingen av hållbara transportsystem. Såväl nationella som kommunala mål omett ökat cyklande tyder på en utbredd tro om att det finns en latent efterfrågan av nycykelinfrastruktur. I dagens cykeltrafikplanering görs ofta ingen åtskillnad mellan nuvarandecykelflöden och latent utnyttjande av infrastrukturen, vilket kan hindra utvecklingen avcykeltrafiken. Det finns därför behov av att utveckla nya metoder för att hitta och påvisa latentefterfrågan. Det har visat sig att analyser baserade på Space Syntax stämmer väl överens medobserverade flöden av gång- och fordonstrafik.

Konst Offentlighet Motstånd Om konst som motstånd i den urbana offentligheten - En fallstudie av konstprojektet (O)önskad samhällsförbättring

This thesis is a cultural theoretical case study of the art project (O)önskad samhällsförbättring.Via an analysis of the project, that is based on theories of power, resistance and contemporaryurban development, it examines the construction of urban space, its impact on public art including the ability of art to initiate evolvement of the urban public space.The last decades art has plaid an important role in what is called the creative city; to become attractive nodal points of the global economy, larger cities increasingly invest in art,culture and creative industry. Simultaneously the urban public space is limited to activitiesand expressions of art that are presumed to create economic growth. This introduces animpression of what is allowed and what is not allowed, possible and not possible, wished andnot wished which, as a consequence, evolves the public space. The events during the artproject and the reactions that followed enlightened these limitations. This tells a story, not only about the structuring process of the local urban space, but also important changes that are created as a simultaneous effect at different levels in society, as well locally as globally.

Det oerhörda i verket : En undersökning av konstverket som ort hos Martin Heidegger

The present essay aims to understand the work of art as place on the basis of Martin Heidegger?s conception of work in Der Ursprung des Kunstwerkes from 1935. That is, a place that cannot be understood in accordance with the physical-technological space, but which cannot either be thought of as mere temporal spacing. This is accomplished by reading Der Ursprung des Kunstwerkes through the shorter essay Die Kunst und der Raum from 1969. Despite the time difference, Die Kunst und der Raum opens up Der Ursprung des Kunstwerkes in such a way that the work cannot be understood as if it were only a temporal event ? as the cause initiating a temporal process or succession of truth.

Examensprojekt: Boxplay ? Utveckling av en kombinationsmöbel

When living in a small apartment one of the greatest challenges is to make to most out of the available space. Several different furniture are used for different purposes.Another issues arise when having peopleover, which requires additional space andseats.

Rum för musik på biblioteket: En fallstudie av Bibliotek 10 i Helsingfors

The aim of this master's thesis is to study how the design of the music library space affects how it is used and its role as an arena for culture. This is done in form of a case study of Library 10 in Helsinki, a public library branch that specializes in music and information technology. The backdrop to the study is the changing context for cultural activity in the information society and the role of public libraries as public space and meeting place. By analyzing the distribution of space in the library, the distribution of functions and artefacts and the spatial use of the room, I interpret the ways in which this distributional logic produces a unique place for music and culture. I discuss the music library design in a space and place perspective, utilizing theoretical tools from cultural geography and the space theories of Henri Lefebvre.

Kommersiella Fastighetshyror och Finansiell Stabilitet

In recent years, global organizations safeguarding financial stability has started to track commercial property markets. One of the reasons for this refers to the fact that commercial property constitutes a large share of bank lending. Simultaneously, bank exposures to commercial property are extensive and risky since collateral values are strongly correlated to borrowers cash flows. Since banks are viewed to play a key role for financial stability, studying the relationship is well motivated. To better understand how commercial property markets interact with financial stability, this paper develops an econometric model for studying the commercial rental market.

Modellering, identifiering och reglering av skannern i ett laserbatymetrisystem

The purpose with this masters thesis was to model the scanner in a system for laser bathymetry. The model was then used to develop a controller for the scanner so a good search pattern was achieved. Two different types of models have been tested, a physical model and a Black Box model of Box Jenkins type. The physical model has been derived from Lagranges equations. Identification experiments have been used to compute the Black Box model and to find the unknown parameters in the physical model.

Folkbiblioteket som socialt rum ? en undersökning av biblioteken i två mindre kommuner

The aim of this thesis is to investigate and increase the understanding of a present function of today´s public library, namely the function of meeting place; here called the social function or social space. Two small town libraries are included in the study, and the questions examined are:How is this function described at the two libraries and what similarities and differences are there between the two? How can one describe the relation between how the library as social space is described in research and at the libraries? The theoretical framework used in examining these questions, consists of three different discourses in culture policy (the discourse of state, market and civil society) and theories on civil society and the public library. A summary of current research makes visible eight different aspects of the public library as a social space. These aspects functions as parts of the theoretical framework as well.

Optimization of Lentivirus Production for Cancer Therapy

Vectors based on lentivirus backbones have revolutionized our ability to transfer genesinto many cell types. Lentiviral vectors integrate into the chromatin of target cells and do not transfer any viral genes causing vector replication. Both of these features arecommonly used in gene therapy and have been used clinically in individuals sufferingfrom cancer, infections and genetic diseases. It has been discovered that T-cells can be genetically modified to be used as effective weapons against cancer: therefore virus mustbe produced to deliver the gene of interest into the T-cells. In this project, lentiviralvectors have been produced to transfer the gene coding for a chimeric antigen receptor(CAR) which is directed to CD19 on B-cells.

Expression av PSI-N från Arabidopsis thaliana i E.coli

PSI-N is one of the subunits in eukaryotic Photosystem I (PSI) and is located on the lumenal side of the thylakoid membrane. It is known to interact in the electron transport chain between plastocyanin and PSI, but the mechanism behind the interaction is still unclear. To achieve a better understanding of PSI-N´s role in the photosynthesis it is necessary to develop a method for purification of PSI-N. The goal with this project was to design a plasmid that encodes a fusion protein containing PSI-N. With use of proteases the fusion protein can be cleaved into purified PSI-N.

Äga rum: Offentliga rum betraktade i ett politiskt perspektiv, fallet Pristina

In order to fully grasp the phenomena 'City' we must understand its political structure as an integrated part of its physical structure and vice versa. This thesis focuses on one crucial element of the City, the public space, and discusses it in relation to the public realm, or sphere, of the City. The aim is to see if it is possible to conceive public space as a spatial dimension of power, and if so, how to analyse this. With the help of the theoretical tool of two ideal types of the configuration of public space, "The city as civic public life" and "The city as authoritarian control" an empirical study is carried out on the case of Prishtina, capital of Kosovo.Conclusions made are that function and use of a city's public spaces can be understood in relation to changes in the political climate of the society. Furthermore, a void in the asset of concepts offered by the ideal types is found ? and therefore also need for new concepts to describe and understand a public space undergoing a dynamic transformation, as being a part of a city in political transition..
