Datorstödd implementering med hjälp av Xilinx System Generator
The development in electronics increases the demand for good design methods and design tools in the field of electrical engeneering. To improve their design methods Ericsson Microwave Systems AB is interested in using computer tools to create a link between the specification and the implementation of a digital system in a FPGA. Xilinx System Generator for DSP is a tool for implementing a model of a digital signalprocessing algorithm in a Xilinx FPGA. To evaluate Xilinx System Generator two testcases has been designed. The testcases are selected to represent the FPGA designs made at Ericsson Microwave Systems.
Framtagande av ny höjdmätningsmetod till försvarets antennhiss 861
This bachelor degree project was carried out at Saab AB Service and Repair, Arboga, Sweden. The objective was to design, construct and implement a new stable and reliable method of measuring the continuous vertical displacement (height) of the military search radar PS861 mounted on a hydraulic powered elevator. The end product needs to be durable enough to be fully operational in the harsh environment of an outdoor elevator shaft and yet as accurate and precise as possible since one of its purposes is to calibrate control equipment. Previously used technique has proven not to meet any of the above mentioned properties.A prototype using a high resolution quadrature output rotary encoder has been developed, allowing a completely digital interface. This new method has been evaluated in laboratory environment where tests have been conducted regarding both reliability and validity.
Antropologins informationsvärldar: En biblioteks- och informationsvetenskaplig studie kring socialantropologer och etnografiska fältarbeten.
The aim of this thesis is to examine information behavioursamongst a group of social anthropologists. The thesis alsohas a special focus on issues concerning information andinformation behaviour during periods of ethnographicfieldwork. As a empirical foundation for this studyinterviews where made between may ? september in 2011with seven social anthropologists active at a swedishuniversity. The results from the conducted interviews areanalysed with the theoretical framework of the informationbehaviour theory as presented by T.D Wilson.
Digital röntgentomosyntes vid lungcancerdiagnostik: möjligheter och begränsningar
Lungcancer är den femte vanligaste cancerformen i Sverige och ofta blir patienten diagnostiserad i ett senare stadium. Inom radiologin utförs oftast först en konventionell tvåbilds-lungröntgen och sedan en datortomografiundersökning (DT) för att med säkerhet kunna diagnostisera och mäta tumören. Eftersom patienten kan genomgå många olika röntgenundersökningar i samband med sitt sjukdomsförlopp, har det därför blivit vanligare att använda sig av digital röntgentomosyntes (DTS). DTS innefattar en betydligt mindre stråldos till patienten i jämförelse med datortomografi men är ändå en mer sensitiv undersökningsmetod i jämförelse med konventionell lungröntgen. Syfte: Vårt syfte var att undersöka om DTS är diagnostiskt försvarbart jämfört med en DT-undersökning, DTS möjligheter och begräsningar vid lungcancerdiagnostik.
Videoproduktion och distribution av gudstjänster
Sammanfattning: Det är minst lika många människor som besöker arrangemang och gudstjänster i kyrkor som besöker idrottsevenemang. Det behövs studiogudstjänster dock sänds det allt färre Tv-gudstjänster direkt från kyrkor och medlen för att göra detta är också på väg att minskas. Många som ser dessa gudstjänster har av olika orsaker inte möjlighet att besöka en kyrka. Detta kan t ex bero på funktionshinder och sjukdom men också att många äldre har svårt att förflytta sig och se gudstjänster live. Ett sätt för kyrkorna att nå ut på bredare front skulle kunna vara att använda sig av Internet som media.Syftet med uppsatsen är att genom intervjuer, användningstestning och slutligen prototyptestning, ta fram en lösning för digital överföring av ljud och bild från ett ställe till ett annat via ett IP-nätverk och finna en avvägning mellan det tekniska och användbarheten då användaren har begränsad teknisk kunskap.Vid datainsamlingen användes en kvalitativ forskningsprocess med intervjuer och observation som insamlingstekniker.
DRM - utveckling, konflikter och framtid : konsumenters reaktioner på och företags användande av DRM
With the digital revolution within video games, the need for Digital Rights Management (DRM) has increased significantly, alongside with the increasing problem of copyright pirates. To counter pirates, DRM was created to prevent illegal copying of software, this to ensure that the Distributors received an income for their work. DRM has, since the start of its use, been getting, a lot of bad criticism from the users of the software protected by DRM. The main function of this paper is to describe the creation and development of DRM by analysis of the vision of different groups on this phenomenon. The main questions are as follows, is it possible to define the very reason for why DRM was created and if so, can its development through time be defined too? What differences in opinions are there when it comes to DRM, counting the two major groups of creators, sellers, distributors (referred to as distributors) versus individual users (referred to as consumers)? In what way will the research results suggest that the future DRM will develop?The development has gone from solving puzzles in a handbook to start the game each time the user wants to play, to serial numbers that is needed during the installation of the game.
Djuren och den ädla människan : Aristokratins roll i den svenska djurskyddsrörelsens framväxt 1875-1905
The aim of this paper is to analyze the influence that aristocrats in Sweden had on the Swedish movement for the prevention of cruelty to animals, and why especially aristocrats started it. The sources I have been using are speeches and texts written by persons who were involved in the movement. I have also studied rapports from the three largest societies for the prevention of cruelty to animals. In the sources I looked for terms, expressions and opinions that can be paralleled whit the aristocratic ideal and opinion. Things that can relate to aristocratic urban people.
Papperstidning eller surfplatta? : En studie om hur surfplattan kommit att påverka svensk tidningspappersindustri.
Vårt sätt att ta till oss nyheter förändras allt mer under digital medias framfart. Informationsflödet är idag snabbare än någonsin tidigare och användandet avelektroniska verktyg som surfplattor blir allt vanligare. Svenska producenter av tidningspapper upplever idag en nedgång i efterfrågan på deras produkt och befinner sig i ett viktigt skede där man måste ta hänsyn till ersättningsprodukter. Tidningspappersindustrins betydelse för det svenska samhället har varit och är idag av stor betydelse. Dess framtid kommer direkt att påverka Sverige på många sätt.
?Ju mer man vet desto mer kan man bestämma? ? En undersökning av behov, sökning och användning av information vid beslutsfattande i kommunala nämnder.
The purpose of this master thesis is to examine some information aspects of decision-making in Swedish municipal committees. Which are the information needs and how do they emerge? How is the needed information sought and received and which are the sources? How do the members of the committees use information when making decisions? To answer these questions qualitative interviews were conducted with four politicians (two chairpersons representing the political majority and two vice-chairpersons representing the opposition) and three officials in a municipality with a population of about 50 000. The politicians were interviewed in capacity of decision-makers, whereas the officials from the local administration are of interest through their decision-supportive role, which includes providing of reports and other information. The examination indicates that even if the conditions to some extent differ between the committees, the administration is highly influential: Notions and proposals about action may come from inhabitants, organizations, politicians etc., but are handled by the administration, which often is the problem formulating actor, through which the informational needs nearly always are canalized.
Ledföljdsvariation i svenska : Verb, semantik och syntax i samband med lång objektsflytt
The term ?Object Shift? means that a weak object pronoun has been raised to a position to the left of a sentence adverbial. Primarily, there are two positions to which a weak object pronoun can be raised; one of them is called Long Object Shift.In this paper, I primarily deal with finite verb frequencies in sentences with Long Object Shift in Swedish. Also, in order to further define the verbs in these sentences I discuss verb semantic and syntactic valence in relation to the shifted object. Furthermore, I discuss the search methods which have generated sentences with Long Object Shift in written sources in Swedish; an equivalent study has never been done before.
Kan vi se, så kan alla det : En studie om hur blinda förhåller sig till Internet i Sverige idag och vilken betydelse det har för deras självständighet och delaktighet.
The purpose of this media scientific study is to contribute to a better understanding about how blind people?s empowerment and participation may affect their role in the digital society.Earlier international studies in this area have shown that blind people not only need more knowledge then the seeing population about the computer, but also about the technology behind their tools for using Internet. The results from these studies have also shown that Internet increases the blind people?s independents and that those who use Internet feel more involved in the society.A qualitative method was chosen to study the three most common categories from the earlier studies: knowledge of technology, empowerment and participation. Are there differences in the results compared to our study in Sweden 2014?Interviews with eight blind, experienced computer users have shown that knowledge of technology is essential for their use of Internet and that the Internet increases their empowerment and their participation.
Miljöpåverkansbedömning vid tillverkning av etanol från cellulosabaserade råvaror : ekologisk gård självförsörjande med drivmedel
Fuel produced from renewable resources is of big interest. In this project the difference between a few different renewable materials are compared on the matter of environmental load when ethanol is produced. The renewable materials that are compared are Salix, straw and reed canary-grass (rörflen). The cellulose in the material is cut down to small pieces and then hydrolysed so that the sugar from the cellulose can be fermented into ethanol.
Tha amount of ethanols that is studied in this work is the smount of ethanol needed to cultivate 1000 ha. The functional unit in the report is 1000 ha.
Mattepainting för heltäckande greenscreen
Vid filminspelning används ofta gröna eller blå skärmar som en del av en bakgrund som förberedelse för infogning av visuella effekter vid postproduktion. Dessa enhetligt färgade ytor kan även omfatta hela scener. Inom digital kompositing används olika element för att ersätta dessa områden med önskat innehåll som integreras med det som filmats. En form av sådant material är den digitala mattepaintingen. Till skillnad från konceptdesign är resultatet inte endast en idé eller ett verktyg utan presenteras i det slutliga klippet.
Digitalisering av bilder vid två museer
The aim of this thesis is to describe digitization of images in two Swedish museums. We want to examine their reasons to digitalize; the administrative and organizational aspects of their work and how they handle the problems of preservation and access to the digitalized images. These problems will be examined through our main questions: Why do the museums choose to digitize their image collections? How are their work organized in terms of staff and economical matters? What kind of software do they use, and which technical solutions do they choose? Which preservation and access strategies for ensuring long-term preservation and access of the digital images do the museums work with? How do the museums select material for digitization? How do they handle the matter of discarding of materials? The study was conducted both by reading text material and interviewing personnel at the two museums. The museums? main reasons for digitization seem to be to protect fragile materials from deterioration and provide greater access to the collections.
Ska Google eller Facebook verkligen få fälla det sista avgörandet? : En kvalitativ studie om hur rekryterare inom mediebranschen ser på arbetssökandes användning av sociala medier
In this thesis recruiter?s attitudes and usage of social media within the media business has been examined. The purpose was to find out whether a certain type of behavior in social media could or could not lead to a future employment. How much weight is put on the virtual identity and what does recruiters look for when the look someone up on the internet. Personal interviews with recruiters were done in six different media companies in Stockholm to find out how they used social media when searching and employing new employers.
