Analys av instyrning och rolldynamik
When driving hard and cornering on a circuit good control of a car?s roll is desired, so the car reaches steady state quickly but yet in a controlled fashion. This control is mainly given by the combination of the cars springs, shock absorbers and anti-roll bars.The aim of this report is to investigate, analyze and measure a Porsche Boxster?s turn in behaviour and roll dynamics as well as with the aid of simulation results give suggestions for improvement of the previous mentioned combination.Two different simulations were made, one based on a simpler model that was based on an evolved version of the bicycle model in Matlab and one was more advanced model in the simulation software rFactor. Measurements of the real car was made using a GPS-based measurement system.

Detta examensarbete har utförts i samarbete med Svedala Compaction Equipment
AB. Examensarbetets primära mål var att reducera höjden på ROPS tillhörande
asfaltvält CC 422. En sänkning medför ett friare vägval och billigare
transporter. Hittills har vägvalet påverkats av broar, viadukter
och andra hinder.
Med hjälp av riktlinjer från Svedala Compaction Equipment AB och Fredy Olssons
modell för integrerad produktutveckling togs kriterier fram, vilka användes vid
bedömning av olika lösningsförslag. Utvärderingen resulterade i att två av de
tio ursprungliga förslagen gick vidare till nästa steg i
produktutvecklingsprocessen - primärkonstruktion.
Primärkonstruktionen inleddes med vidareutveckling av de två
principförslagen.

Det Andra Afrika En kritisk diskursanalys av SVT:s Korrespondenternas representation av Afrika
Discussions of structural racism has now moved to the forefront of the Swedish society, and many researchers have sought to understand what form it takes, how it is manifested, how it is exploited and challenged. At the core of this debate we find the media, and its logic embedded with mechanisms of simplification and polarization.Media is our key source of knowledge and information, why it also affects our norms, beliefs and preconceptions. Media thus has the power to mediate, amplify or challenge how we conceptualize the world, and subsequently our (unconscious) racist beliefs.To investigate how media content is influenced by underlying colonial or racist assumptions and stereotypes thus becomes a way to investigate our understanding of reality.In accordance with postcolonial thought, structural and symbolic racism is embedded in language and hidden in images, and surface in the form of domination and feminization, and the portrayal of the subaltern ?Other? as passive and irrational.This paper thus departs from postcolonial theory and media logic to undercover hidden patterns of structural, symbolic and historically contingent racism in one of Sweden?s most prominent in-depth foreign TV-magazines, namely Korrespondenterna.Adopting Critical Discourse Analysis (CDA), this paper explores to what extent racist and colonial stereotypes are reproduced and/or challenged in Korrespondenterna?s representation of Sub-Saharan Africa.In line with postcolonial theory it is found that historically contingent racialized stereotypes are prevalent in Korrespondenterna, and that tendencies of portraying Africa and Africans as passive, feminine and irrational are prevailing.It is thus argued that media logic, imbedded with mechanisms of simplification, polarization and intensification, contributes to the use of colonial stereotypes in media, and thus to the mediation of structural and symbolic racism..

In order to become a market leader even with their harvester, the company decided to change the harvester to have a swivel and a leveling driver cabin.The aim with this bachelor?s degree thesis was to develop a design concept for the harvester driver cabin, which Gremo AB can apply on the new harvester.
Transportsfordon för rullstolsburna
A vehicle that carries a person sitting in a wheelchair has been rebuilt. The original vehicle was provided with a petrol engine, hydrostatic drive and a mechanical steering rod, making it noisy and hard to maneuver. The purpose with this project was to convert the vehicle to make it more environmental and easier to drive.A new design has been proposed where an electrical drive has replaced the noisy combustion engine and an electrical motor with joystick control has replaced the manual steering.The project was divided into two parts. One mechanical part where the construction of the drive and steering were to be decided. The other part involved programming the microprocessor and implementation of all the necessary electrical for the control system of the vehicle.
"Att känna sig som något lätt fjäderaktigt" : äldre människors upplevda hälsa och vårdande som stödjer deras hälsoprocess på särskilt boende
Aim: The aim of this study was to describe intensive care nurses? experiences communicating with patients during mechanical ventilation.Methods/design: A qualitative interview study. Interviews where analyzed using descriptive content analysisSetting: Nine intensive care nurses from two different intensive care units were interviewed using a semi structured interview guide.Background: Past research has shown that patients during mechanical ventilation in the intensive care unit, feel very vulnerable and the helplessness of being unable to speak. These patients feels that they are completely dependent on the nurses and their competence. It has been shown to be very important that the patient feels included, acknowledged and respected.Results: The analyzed data resulted in a theme; through communication strive to preserve patients´ dignity and three main categories; create relationship to the patient, minimize patients´ vulnerability and don´t give up.
Identitetsverifiering via tangentbordsstatistik
One important issue faced by companies is to secure their information and resources from intrusions. For accessing a resource almost every system uses the approach of assigning a unique username and a password to all legitimate users. This approach has a major drawback. If an intruder gets the above information then he can become a big threat for the company and its resources. To strengthen the computer security there are several biometric methods for identity verification which are based on the human body?s unique characteristics and behavior including fingerprints, face recognition, retina scan and signatures.
Om förtryckande strukturer
This paper is a critique of an article in the Swedish magazine Filosofisk Tidskrift (Philosophical Magazine), in which professor Per Bauhn maintains that there is something wrong with having a group perspective in moral and political matters. In this article Bauhn makes three conclusions. The first one is that you violate Hume's law if you draw the conclusion that something is an oppression only from descriptive premises, which for example communitarians does according to Bauhn. He argues that ?oppression? is a normative term, and therefore it requires at least one normative premise.

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.
