Radio Frequency Identification, RFID, is a convenient way to enable contactless identification which does not require any physical nor optical contact. As with any radio-based communication the signal can be intercepted, thus making the technology vulnerable to several kinds of attacks. Interception of communication is not the only threat. Since RFID tags might contain personal information or information that will grant the owner access to secure areas, skimming and spoofing attacks are also major threats against this technology. In this thesis report, the perspective of an adversary is portrayed in an RFID-enabled environment by presenting where RFID is used and how it could be abused.
Vem är ett barn? En kritisk idéanalys av Barnkonventionen
Nearly half of the worlds population is individuals under the age of eighteen. The UN Convention on the Rights of the Child state in its first article that a child is ?every human being below the age of 18 years?. Our aim and purpose with this essay is to problemize this broad definition. Our hypothesis is that the definition brought by the UN Convention on the Rights of the Child is too wide and therefore brings difficulties when children of different ages beneath eighteen should and shall be treated the same.

Fastighetsbildning inom strandskyddat område : En studie av tillämpningen i två kommuner
Stränder och strandnära områden utgör i många avseenden en värdefull miljö som i Sverige skyddas tack vare vår strandskyddslagstiftning. Strandskyddslagstiftningen är en naturvårdsföreskrift som syftar till att trygga allmänhetens tillgång till stränder och bevara goda livsvillkor för växt- och djurlivet. Skyddet är generellt, dvs gäller alla stränder i Sverige och innebär bl a ett förbud mot uppförande av ny bebyggelse. Fastighetsbildning inom strandskyddat område utgör en åtgärd där hänsyn måste tas till strandskyddsbestämmelserna. Åtgärden kräver en bedömning där förrättningslantmätaren, efter vederbörligt samråd med kommunen eller länsstyrelsen, avgör om strandskyddets syfte motverkas eller inte.

Demokrati - skyddar det mot fred? : ? en teoriprövande fallstudie på konflikten mellan Ryssland och Georgien 2008
The aim of the following paper has been to test the democratic peace theory through applying it on the conflict between Russia and Georgia in 2008. This to either falsify the theory or come to the conclusion that the states? democracy was not satisfactory in regards to the definition of liberal democracy. The questions asked are: Was Russia and Georgia democratic states? Is democracy a protection from war? And which aspects of the liberal democratic theory, if any, were not satisfactory in either of the countries? The results show that the democratic peace theory is valid in this case and that neither one of the states were democratic.
Konstruktion av mutterdragare för stora moment
This degree project was conducted in collaboration with Gremo AB located in Ätran.The aim of the project was to develop a solution to secure quality and to help assemblingthe locknut holding the vertical hinge on the harvesters and foresters from Gremo.At this time the nut is assembled manually by the aid of an overhead crane. The nut istightened differently from time to time, and there was no specified torque to which it istightened. Another present problem was the locking washer which sometimes getsdamaged during assembly, when this happens the procedure has to be started over fromthe beginning. The current assembly procedure is very time consuming and lengthy forthe employees.Our task was to design a machine that could tighten the nut to a specified torque with amargin of error of ± 3%. The assembly procedure will be held simple and the timerequired at a minimum.The project started by developing several principle solutions, the one solution that bestmatched our specifications were developed to a primary solution.Today we have started manufacturing and assembling our prototype.
Konstruktion av elektrolytisk ozongenerator
The work has been carried out in cooperation with the company Zenit Design in Malmö. The project's goal was to restore, improve and produce an ozone generator. During the project, the authors sought relevant literature in databases, been in contact with US suppliers of fuel cell membranes, Asian suppliers for the processing of Teflon and Titanium parts in mechanical engineering and Swedish suppliers of various standard components. The authors had access to a temporary lab at Zenit and electron microscope at Halmstad University where material tests were performed. The authors have also had access to measurement equipment to measure amounts of ozone.During the work, the authors have mapped how an existing ozone generator works and then have their own development.

Erfarenheter av utedrift med köttdjur i Sverige och Kanada :
Beef cattle wintering outdoors should be provided a shelter, e.g. a type of barn or corresponding. This type of production requires appropriate soil types and secured animal welfare. For example, a clean and dry resting place needs to be provided to the animals. To receive an exemption for buildings the farmer has to have something equivalent that provides an adequate shelter.
Den försvinnande staten Tuvalu : En fallstudie om klimatflyktingars rättigheter och staters ansvar
This thesis aimed to, with the help of a case study, investigate and discuss state responsibility towards climate refugees. The state of Tuvalu was selected because of their vulnerability as a low-lying island state. This was fulfilled by on-site study how the state Tuvalu acted to climate threats, determine if the future migrants from Tuvalu can be counted as climate refugees and find out if they are by that definition included by the UN Refugee Convention. The result indicated that the state of Tuvalu is adapting to climate threats, that in the future the population can be seen as climate refugees, if they are forced from their homes due to climate change, and that they, despite that definition, can not be included by the UN Refugee Convention. The study also indicates a need for greater international protection of climate refugees by, for example, an expansion of the UN Refugee Convention so that these vulnerable people do not fall into oblivion due to a question of definition..
Industrialisering av konsumentprodukt : Från inkommande material till färdigvarulager
This report examines the industrialization of a newly developed household machine on behalf of Technogarden Engineering Resources in Karlstad, Sweden. The report is a part of the final course in the Bachelor Program in Mechanical Engineering at Karlstad University and takes place in spring 2014.An innovator, an investor and a engineering consultant firm have through collaboration developed a new type of gruel machine. The product is in its final stage of construction and is planned to be manufactured in a production located in Sweden, autumn of 2014.To compete against today?s trend in outsourcing manufacturing to low cost countries for better profitability, the industrialization of the gruel machine must be done with a minimum amount of resources in order to become successful, which also describes the problem of this study. Using pre-study material in form of Lean production literature, visiting a successful production site and gathering data from involved engineers a specification was developed which describes what this industrialization must achieve and which requests can be accomplished.

Klara färdiga gå : en gestaltning för ökad fysisk aktivitet i urbana rum
The title: ?Klara färdiga GÅ? can be translated as ?Ready steady GO?, and is ment as a request to start move. In this project I want to invite people to walk more by creating creative, demanding and playful walkways and paths, where the body can be allowed to work just a tiny bit harder.It?s because walking means exercise and fresh air, for free and without spetial equipment. Walking can also be fun, it allows people to stop, change direction and experience things.I think activity should be fun, inspired by children playground my project is a contribution to how adults might stay healthier in a city, where too often healthy activity is solely confined to the gym or sports fields.
