Human Terrain System : En kartläggning av debatten kring vetenskapsetik

Antropologer anställs idag av amerikanska försvarsmakten inom Human Terrain System. Denna enhet skall med sin expertiskunskap leverera socio-kulturell data till militära beslutsfattare på högre nivåer. Detta har i USA vållat stor debatt, främst vad gäller den vetenskapsetiska aspekten av projektet. Kritiker till HTS menar att det strider emot vetenskapsetiska riktlinjer och god vetenskaplig sed att bedriva forskning på människor där risk föreligger att de kan komma till skada. Syftet bakom uppsatsen är att kartlägga debatten för att se hur denna har förts mellan debattörerna.Debatten har analyserats utifrån artiklar, internetmaterial, samt litterära källor.

On-line uppdragsplanering baserad på prediktionsreglering

Modern air battles are very dynamic and fast, and put extreme pressure on pilots. In some unpredictable situations, like new discovered threats or mission plan deviation because of enemy aircraft, the pilots might need to replan their predefined flight route. This is very difficult, if not impossible, to do since numerous factors affect it. A system that can help the pilots to do such a thing is needed. Previous work in this field has involved methods from artificial intelligence like A*-search.

Sånger från graven: En kartläggning av krafterna som hämnar den digitala revolutionen inom svensk musikdistribution

Songs from the Crypt: Mapping the Forces that Hinder the Digital Revolution of Music Distribution This paper seeks an explanation to the low market share growth of the commercial digital music distribution in Sweden. The analysis identifies a spectrum of obstacles that hinder the digital distribution technology from becoming the main form of music distribution in Sweden. These obstacles make the digital music distribution less favourable in comparison with physical distribution from the consumer?s point of view. The authors suggest that in order for the digital distribution of music to become competitive the digital product would either have to be developed further to offer more customer value or the so called a là carte retail model would have to be replaced by a subscription-based distribution model.

En fordonsförares upplevelse av accelerationer som grund för en effektiv simuleringsmodell

Saab Aerosystems has a long tradition and a lot of competence in the field of flight simulation. Their ambition to broaden the market horizon has led to a discussion about also selling vehicle simulation solutions, both for military and civilian use.The aim of this thesis is to investigate the driver?s experiences of the accelerations he or she is exposed to whilst driving in rough terrain. The results may be used as a basis for future decisions and can act as a platform for the construction of an effective simulation model.To investigate the driver?s exposure of acceleration, some kind of dynamic simulation is needed.

Den elektroniska handelns förutsättningar via digital-TV kontra Internet

Syftet med denna undersökning är att ta reda på vad den elektroniska handeln via digital-TV har för förutsättningar att slå sig in på den redan befintliga marknaden där bland annat Internet finns. Elektronisk handel via digital-TV är en tjänst som inte finns idag, men som skall introduceras under hösten 1999.Eftersom handel via digital-TV inte finns i dagsläget, har en jämförelse gjorts mellan digital-TV och Internet för att på så sätt få ett mer konkret resultat vad det gäller digital-TV. Den elektroniska handeln via Internet är på frammarsch och om tekniken fungerar bra på Internet, kan erfarenheterna även utnyttjas och användas på digital-TV.Rapportens resultat visar att den elektroniska handeln via digital-TV kommer att fungera och även att handel via digital-TV kommer att bli ett komplement till Internet. Rapporten visar också vilka produkter och tjänster som kommer att finnas tillgängligt via digital-TV..

Vad tycker Mario om bibliotek? ? Onlinespelares användning och uppfattning av bibliotek

The aim of this thesis is to fill a knowledge gap regarding how online players use libraries, their attitude towards libraries and what they want out of future libraries. We see it as a problem that the library world of today does not have much knowledge about an audience that is so prevalent in society.The theory used in the thesis is Henrik Jochumsen, Casper Rasmussen Hvenegaard & Dorte Skot-Hansens model that divides libraries into four functions. The four functions are meetings, knowledge, inspiration and experiences. In the analysis we added a suggested fifth function, a digital space, giving the digital interaction and information needs of today´s society. The method was focus groups on online forums for gamers.

Tetratermmodellering och regressionsanalyser mellan topografi, tetraterm och tillväxt hos sitkagran och lärk : en studie i norra Island

This study was made in an attempt to give the forest research centre Mógilsá a producedtetratherm map and a better understanding of how topography and temperature influencethe growth of two tree species. The digital tetratherm map model, covering the northernpart of Iceland, was developed to investigate the correlation between tetratherm and thegrowth of Picea sitchensis and Larix (sukaczewii + sibirica). The study confirms theusefulness of Digital terrain models in providing data for a lot of different factors and forthe tetratherm model. Hopefully will this tetratherm map be used in future studies.Secondly, investigations were made correlating the growth of the two species againsttopographic factors representing height above sea level, distance to the sea, slope andtopex. Thirdly, investigations were made comparing the aspect and the ground shape tothe growth.The growth rate of Larix had strong significant correlations to the tetratherm and thedistance to the sea- factors.

Real-time rendering of large terrains using algorithms for continuous level of detail

Three-dimensional computer graphics enjoys a wide range of applications of which games and movies are only few examples. By incorporating three-dimensional computer graphics in to a simulator the simulator is able to provide the operator with visual feedback during a simulation. Simulators come in many different flavors where flight and radar simulators are two types in which three-dimensional rendering of large terrains constitutes a central component.Ericsson Microwave Systems (EMW) in Skövde is searching for an algorithm that (a) can handle terrain data that is larger than physical memory and (b) has an adjustable error metric that can be used to reduce terrain detail level if an increase in load on other critical parts of the system is observed. The aim of this paper is to identify and evaluate existing algorithms for terrain rendering in order to find those that meet EMW: s requirements. The objectives are to (i) perform a literature survey over existing algorithms, (ii) implement these algorithms and (iii) develop a test environment in which these algorithms can be evaluated form a performance perspective.The literature survey revealed that the algorithm developed by Lindstrom and Pascucci (2001) is the only algorithm of those examined that succeeded to fulfill the requirements without modifications or extra software.

Gapet: En studie om gapet mellan leverantörer och köpare av digital skyltning

The aim of this study is to describe the market for Digital Signage in Sweden and give the reader an increased insight and understanding of the problems that suppliers and buyers of Digital Signage may encounter. The study is abductive and based on a number of qualitative interviews with representatives from potential buyers, an existing user, a supplier and a number of companies with insight into Digital Signage. Our findings show that the companies in this study have not yet reached the stage of being ready to invest in a system for Digital Signage, since the effects on for instance increased sales and potential savings on marketing communication have not yet been clearly proven. Furthermore the study shows that it is important that a supplier has a fundamental understanding of the business model of the buyer. In addition to this, service, support and IT-related issues are of great importance for the potential buyers.

Metod för användning av Geografiska Informations System vid långsiktig vägplanering : en studie genomförd på Sveaskogs marker i Norrbotten

The forest industry is one of the most important industry branches in Sweden. Since the demand of high precision wood deliveries has increased, the demand on a well constructed forest road net also has increased. A good road net gives the wood-supplier competition advantages and also increases its service level towards its customers, lumber-mills and pulp-mills. In some parts of Norrbotten, the road net is still insufficient and not yet built out enough, and that is why it is important to know how to act and where to improve the road net in these areas. The purpose of this thesis was to create a work-model for long term road planning in areas with no road net or a not yet complete road net. The model has been created in an ArcGis environment, where a long chain of tools has been tied together with the program ?Model builder?.

Simulering av översvämningar i Nedre Dalälven

Mosquitoes are found in extremely large numbers in the lower parts of the River Dalälven. In the year 2000 the mosquito nuisance was especially high, resulting in foundation of the Biological mosquito control project. Since 2001 mosquito larvae are controlled by using a biological pesticide BTI (Bacillus thuringiensis ssp israelensis). The mosquito fauna in the area is dominated by flood water mosquitoes, a group of mosquitoes that are very aggressive and form new generations of mosquitoes during every single flooding event during the summer. To be able to efficiently control the mosquitoes it is essential to know the extension and locality of the flooding.

Kombinerad bekämpning i strid i bebyggelse

Even though battles have been fought in built-up areas for a long time, there have not been any specific theories connected to it. As the world becomes increasingly urbanized, the problem of not having any complete theories with which to analyze military operations in urban terrain becomes bigger. This essay aims to contribute to the field of military theory by investigating if Robert Leonhard?s theory of combined arms can be used in analyzing such operations and to be able to explaining the outcome of them. The main question posed in this essay is; to what extent can Leonhard?s theory explain the outcome of military operations in urban terrain? The method used to answer this question is a comparative method formed as a case study of two military operations in urban terrain, Operation Vigilant Resolve and Operation Phantom Fury, which both took place in Fallujah during the Iraq war 2004. The intention is to test Leonhard?s theory in both cases by assigning the theory several indicators, which are tested in each case. The result shows that the indicators appeared almost equally in both cases, even though one of the operations was said to be a success and the other a failure.

Tjänsteorienterad arkitektur : Ett arkiv- och informationsvetenskapligt perspektiv på tjänsteorienterad arkitektur

The starting point of this paper has to do with rapid changes within the information technology and the need for agile and fast systems. The primary goal is to investigate what happens with recordkeeping practices in agile environments like service oriented architecture (SOA). It is in the possible transfer between IT architecture and digital archive the area of this paper resides. The paper relates to the Records Continuum model by which records will be considered historical and active at the time of creation. In the Records Continuum model recordkeeping practices and archival requirements will have to be taken into account at the time of creation.This paper concerns SOA from the perspective of Archival and Information science.
