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..

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.

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.

Användarupplevelse av ett komplext infotainmentsystem i en bil. En verklighetsbaserad studie av gränssnittet mellan människa och fordon

In recent decades here has been a huge development in information technology (IT), where we humans are increasingly using IT in our daily lives, ranging from social media to music streaming services; this has also been a reflection of the technologies developed to our cars. Infotainment systems have become an increasingly regular feature in modern cars where the high degree of integration such as navigation, mobile and Internet has become more common and more sought after. Despite this, relatively little research problemized User Experience of a complex infotainment system in a car. This study thus has the intention to consider the relevance of reality based tests by examining how the user experiences a complex infotainment system in a car. We asked ourselves; How do the user experience a complex infotainment system in a car? We conducted our qualitative study, an interview with researchers in the field of vehicle and road safety and designed a number of system-related activities in a test session where we observed three users.

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.

Utbyggnadsplan för laddinfrastruktur inom Uppsalahem AB:s bostadsområden

The electric car has existed for over a century and producers has tried to commercialize it earlier but has not succeeded. In recent years, however, a change occurred that may be significant for the electric car and it is now to commercialize in the market of passenger cars. The technology has in recent years elaborated as more car manufacturers have started to invest in development in the subject field. This thesis aims to compile an action plan for the development of charging infrastructure for electric vehicles in Uppsalahem ABs residential areas. It is based on a survey of different residential areas and a survey of charging infrastructure.

Energianvändning för markkonstruktioner förlagda med ytvärme : En teknisk och ekonomisk utredning av fördelarna med att isolera under värmerören

The need for snow-free surfaces at squares, bus stops, platforms, car parks and sports facilities increases and at the same time energy price rise and the environment is becoming a hotter issue. The construction of the ground heating systems often lack thermal insulation under the heating pipes, which means that the heat from the pipes not only warm up the soil surface but also heats the surrounding soil. The insulation also has more features, by insulating the risk of frost damage is minimized. The goal of this report is to demonstrate the large heat loss and energy costs in the absence of insulation under the heating system.The report begins with a scientific way to study and treating the soil heating system uses, and the theory involved. Furthermore it also deals with different routing principles of heat pipes depending on the facility.All calculations are made with so called finite element method (FEM), in COMSOL Multiphysics 3,5a, where models are created with different conditions.

Modell för dimensionering av AGV-system inom tung industri

Interest in the implementation of AGV-systems (Automated Guided Vehicle) has in recent decades increased. The reason is that it allows companies to perform reliably and secure internal transport while reducing the need of personnel. It is one of todays most advanced and complex material handling system that can independently make their own decisions regarding flow paths and traffic control. An AGV-system consists of transport units carrying cargo from point A to point B, and communicates using a computer.The purpose of this study is to develop a model on how to proceed in order to design an AGV system in heavy industry. The model is tested by a case study of a company in the metal industry to determine if the model works and gives the correct result.

Konceptförslag till förarmiljö : Formspråk och utvalda reglage i estetisk och kognitiv ergonomisk tappning

Ett produktutvecklingsprojekt som behandlar hur problemen kring en förarmiljös formspråk, reglage och kombinationen av dessa i högre grad kan utformas på ett kognitivtergonomiskt och estetiskt vis med anknytning till varumärke.I projektet utfördes en omfattande studie över nutidens förarmiljöer där flera tydliga trender upptäcktes.  I parallellkurs utfördes ett kognitiv ergonomiskt praktikfall tillsammans med litteratur som förankrat arbetet i att forma tekniken efter människan.  Sedan har projektet fördjupat i estetiska principer och olika studier kring förarmiljöer behandlas. Konceptframtagningen bestod av tre faser. Där det initialt togs fram en mängd övergripande formspråk. Sedan lades de åt sidan för att utforma manöverdon.

Stridsfordon 9040, en krigsmaskin i en internationell kontext

Den svenska Försvarsmakten har under en smärtsam process genomgått en reform från det gamla invasionsförsvaret till det nya insatsförsvaret. Det har i sin tur påverkat var och när uppgifter skall lösas, den mentala förberedelsen syftar inte längre till att enbart försvara rikets gränser. Svenskatrupper finns idag på ett flertal platser världen men jag vill belysa insatsen i Afghanistan. Den svensk/finska kontingenten har förstärkts med Stridsfordon 9040, ett system konstruerat för ett subarktiskt klimat. Denna uppsats vill bidra med en uppfattning om Stridsfordon 90 är lämpad att lösa uppgifter i Afghanistan och i förlängningen ge ett underlag för en diskussion om det är rätt att systemet finns i insatsområdet.

?De räknas inte som svenskar i mina ögon? En studie av attityder till islam och muslimer hos elever på gymnasiets yrkesförberedande linjer med ett intersektionellt perspektiv

This essay aims to broaden the understanding of intolerance towards people with religious and/or cultural Islamic association or background. This thesis has intolerance and Islamophobia as central components and starts with the question: In what manner do twelve pupils talk about Islam and Muslims in their third year of the vocational program, in small towns and in the countryside? The survey took place in the south of Sweden in a rural municipality where a total of twelve students from the industrial, electricity and vehicle program in the Swedish gymnasiums participated in two separate focus group interviews. The essay will use an intersectional analysis to see where the students position themselves and Muslims in relation to each other and to society. The essay also contains a comparison of Islamophobia in the country side and in the city environment.
