Metafor - Tao : En komparativ studie i metaforik mellan prekonfuciansk tanketradition och svensk nutid
Metaphors and their use as a rethorical vehicle are examined. Two texts, one in Chinese and one in Swedish, are compared and analyzed to determine the extent to which the associations they create successfully capture the author's intent. Seecondarily, a shift from the assumptions that rhetorical analyses often assume (read: antiquity and Aristotles) to a more abstract internal human platform is suggested. Neurological and cognitive research is cited in support of this shift.The essay examines the question: How can metaphoric contribute to conveying the communicator's intention? By comparing metaphorics used by an historical Chinese rhetor with those used by a contemporary Swedish rhetor.
Fundament för kompaktkran : En universell lösning
This thesis describes the universalization, improvement and further development of acompact crane support frame for flatbed trucks. The work has been conducted at Eloch Fordonsteknik AB (henceforth EFAB) in Uppsala.The aim of the work has been to shorten the assembly time of the product. By doingso, the product can be kept on shelf, which in turn results in shorter lead time. Thishas been done by universalizing the support frame to be compatible with most of thechassis EFAB works with. Additionally, the entire construction has been made lighter,which will make it a more attractive choice for customers.A pre-study was conducted and information was gathered internally, as well asexternally, in order to ascertain that no limitation or possibility was overlookedduring the course of the project.One such limitation has been the geometry of the truck bed that the support frameshall be compatible with.
Design och Implementering av en IntuitivKontrollmetod för Larvbandsdrivna UGV:er
SammanfattningDenna uppsats beskriver design och implementering av en mer effektiv metod att styrakameraförsedda radiostyrda markfordon (UGV av engelskans Unmanned GroundVehicle). Det åstadkoms genom att införa samma kontroller som är vanliga i actionspel iförsta persons perspektiv, så kallat Free Look Control (FLC). Miljontals spelare kommeratt känna igen och vara bekväma med styrprincipen, vilket borde reducera dengenomsnittliga träningstiden samt förbättra prestationsförmågan. FLC gör det möjligt föroperatören att kontrollera kamerans läge direkt istället för via fordonet den sitter på.Detta görs genom att i mjukvara sammankoppla fordonets och kamerans rörelser.Utöver författandet av denna uppsats byggs en fungerande UGV-prototyp som kanstyras enligt både FLC och dagens standard, Tank Control (TC). Detta gör det lätt attdemonstrera skillnader mellan metoderna.Arbetet utförs åt institutionen Flyg- och systemteknik inom FOI, Totalförsvaretsforskningsinstitut, för att demonstrera och marknadsföra konceptet att använda FLC förstyrning av obemannade markfordon.Nyckelord: Odometri, Kalman filter, UGV, Unmanned Ground Vehicle, obemannademarkfordon, FLC, Free Look Control, FPS, First Person Shooter, fjärrstyrning..
En undersökning av ITs nytta för transportorganisationer
Målet med studien har varit att ta reda på hur man med hjälp av IT kan stödja enimplementering av IT-baserad planering inom transportbranschen, mer specifikt ruttplaneringsamt se vad som krävs för att reducera den stora mängd komplexitet som omger den. I fleraartiklar från Computer Sweden diskuteras det att man med hjälp av IT-stöd kan minskakostnaderna, öka inkomsterna och arbeta på ett mer klimatsmart sätt. För att få kunskap omområdet har Gayialis och Tatsiopoulos artikel Design of an IT-driven decision and supportsystem for vehicle routing and scheduling använts som kunskapskälla och som ett anpassatteoretiskt ramverk efter vår studie. Vidare har litteraturstudier utförts inom logistikområdet.För att bygga upp en empiri har en kvalitativ intervju genomförts samt en undersökning avbranschanpassade IT-lösningar. Resultatet av datainsamlingen blev en punktlista på komplexaparametrar som måste hanteras av den undersökta transportorganisationen för att uppnåeffektiviseringsvinster med hjälp av IT-baserad transportplanering.
Elhybridteknik i bandvagnssystemet : Den militära nyttan i logistikfunktionen
Fossila bränslen är ändliga resurser och FMV menar i sin Tekniska Prognos 2013 att Försvarsmakten redan nu bör planera för en omställning till alternativa tekniker till dagens förbränningsmotor. Den teknik som verkar mest lämplig som interimslösning mellan framtidens vision om ren eldrift och förbränningsmotorn är elhybridteknik. Uppsatsen undersöker hur Försvarsmaktens logistikfunktion påverkas om bandvagnssystemet skulle övergå till seriehybridteknik. Uppsatsens ansats är kvalitativ med en kombination av textstudier, intervjuer samt ett frågeformulär som besvaras av totalt tre personer fördelat på Amf1, FMTS och I19 där samtliga innehar mångårig erfarenhet av bandvagnssystemet. Formulären kompletteras med intervjuer med dessa personer samt personer på BAE Systems som bidrar med teknisk expertis.
Förstärkning av betongkonstruktioner med kolfiber med avseende på olika brottstyper
The purpose of this report is to simplify the process of designing carbon fiber strengthening for existing concrete constructions, specifically beams. The intention has been to establish a flow chart containing information on the necessary testing and calculations for the design, to as far degree it is possible satisfy the requirements stipulated by Swedish and by extension, European authorities.To do this the report will examine a parking garage situated underground by Akademiska Sjukhuset, Uppsala. The parking garage was built in the mid-seventies, and has in recent years been subjected to a greater load than designed for by the construction of a road on top of it. FEM-Design has been used to obtain the internalforces of the beams and thereby determine whether they are in need of strengthening or not and thereafter design the strengthening according to Täljsten (2006) with some corrections from Täljsten (2011) due to new regulations.The result of this report is that the flow chart used is viable to design carbon fiber strengthening, atleast with the conditions met in our reference project.The conclusion drawn after working with this report is that there is a need for a clear standard for carbon fiber strengthening , preferably a standard that can be used throughout Europe..
Marknadsanalys av ett svenskt transportsystem med höghastighetsgodståg.
In Sweden plans to build high speed railways have been around since the early 1990s and the planshave developed to be more precised since. The future Swedish high-speed rail network is supposedto consist of two lines. Götalandsbanan; from Stockholm to Gothenburg, and Europabanan fromJönköping through the Öresund Region to Hamburg.The description of the aim to build high-speed railways in Sweden has in former reports always beento achieve rapid passenger traffic between big Scandinavian cities and Europe. There are almostnothing mentioned about the possibilities of high-speed transports of cargo on these railways. Thisstudy aims to clarify the freight transport market for Götalandsbanan and Europabanan.Today there is only one transport system with high-speed freight trains.
Skadeanalys och omkonstruktion av HMS Belos A-ram
In order to rescue a distressed submarine crew, the Swedish Navy is able to use a deep submergence rescue vehicle, DSRV. This mini submarine ascends, docks to the downed submarine and picks up the whole crew. The submarine rescue ship HMS Belos has a special crane located in the aft of the ship to lift the surfaced DSRV aboard, which then docks on to the on board pressure chambers located below deck. During inspections the aforementioned crane has shown to have problems with cracks in the structure, most of them located in the bolted joint between the top part of the crane and the two leg parts. A simulation of the forces acting on the structure in heavy sea condition was conducted; these values were then used as input values in a Finite Element Method, FEM, analysis of the joint.
En knuten näve i silkeshandske - Kan statliga informationskampanjer stärka samhället och medborgaren?
Public opinion can be shaped as well as transformed in a number of ways. Government authorities occasionally make use of public information campaigns to educate and steer the public. In this thesis the balance between public and private, the individual and the society is analysed in terms of dimensions of individualism and communitarianism. These dissimilar theories on how the society ought to be constructed can be used when analysing many different policy areas, however, they also pinpoint the controversies seen in the public debate regarding Swedish information policy. Based on this analysis an empirical study identifies what kind of knowledge the state wants the citizens to possess and public information campaigns can be problematic.
För sakens skull : Det omöjliga mötet i Rut Hillarps roman Sindhia - en lacansk läsning
This essay examines the love affair between the two main characters of Rut Hillarp?s novel Sindhia. It draws attention to the schism between the Surrealist version of love as an extatic-religious fusion of the sexes ? that in a way marks the relationship ? and the yet remarkable coolness between the two lovers.With the theories of French psychoanalyst Jacques Lacan, I will show how the man and the woman project their unrealistic individual fantasies on each other, thus rendering impossible the Surrealist Meeting, with its road to an absolute reality. The Surrealist "l?amour fou", I will argue, is trapped in the ritualized "l?amor interruptus"; a lacanian term for a certain kind of love that wishes to conceal the fact that desire will never find its object.
Externhandelns konsekvenser för cityhandeln, i skenet av en ny trafikled : En studie om Söderslättetableringens och Umeåprojektets betydelse förhandeln i Umeå

Umeå is the study object with interesting undergoing changes including a new external retail area south of the city and a new transport route that will lead the through traffic around the city.The study is based on a review of previous studies and a qualitative method. Four interviews were conducted with people who have a connection to commerce and/or municipal planning and where considered able to contribute with rich and relevant information. The result shows that the commerce in Umeå will be significantly strengthened in the context of a new external commercial establishment when the city?s overall attractiveness increases.
Informationssäkerhet i en mediekoncern : Ett penetrationstest med inriktning på datautvinning och social-engineering
Målet med denna rapport är att studera informationssäkerheten på ett företag i den svenska mediebranschen. Att upprätthålla en bra informationssäkerhet är särskilt viktigt för ett medieföretag, då de dagligen hanterar källskyddat material. För att komma över känslig information utfördes penetrationstester genom social-engineering och datautvinning. Resultaten av dessa tester visade att det var relativt enkelt för en angripare att få de anställda att ge ifrån sig lösenord till företagets interna nätverk och VPN-klienter. Datautvinningen visade även att i princip all information gick att utvinna eller återskapa från företagets datorer eftersom man inte använde någon form av kryptering.
Trafikstyrning med variabel trafikutrustning : en behovsanalys för Vägverket Region Stockholm
When traffic in large cities increases, it becomes more vulnerable to disturbances such as accidents, stalled vehicles or construction; therefore, traffic jams are more likely to occur. For better control of the traffic at a disturbance the Swedish National Road Administration (SNRA) has traffic equipment which can be controlled from a command centre. This traffic equipment consists of gates and signs with variable messages. This report will discuss the system used for traffic control in Stockholm. It will present proposals designed to improve it.
Modellering av ett bränslesystem i Modelica : tillämpat på ett obemannat flygplan
Mathematical models possible to simulate are of great importance in order to make successful projects in the aircraft manufacturing industry. An aircraft fuel system is very complex, containing pipes, tanks, orifices, valves and pumps. The principal of this thesis is using the tool Easy5, which no longer is considered reliable enough in terms of development and support. This thesis tries to evaluate the Modelica language as a possible alternative to Easy5. To make this evaluation, the components concerned in the fuel library in Easy5 are implemented to the Modelica language.
Längs en och samma grusväg. En studie om författarna till några handskrivna sångböcker från sekelskiftet 1900.
Title: Along one and the same road - a study of the people behind some hand written song books from around the turn of the 19th century. It is based on some hand written songbooks found in homes along the small byroad in Kruse, Alva, Gotland. My own connection to the place is that I was born in one of these houses. During the summer of 2008 interviews were made with four people who live or have lived along this road themselves. Some of them have even lived in the same houses as the owners of the books.
