Förenliga motsatser? : En jÀmförande studie om aggregering och deliberation i tvÄ e-petitionssystem
This essay sets out to compare political participation in two e-petition systems: The Malmö initiative in Malmö, Sweden, and Better Reykjavik in Reykjavik, Iceland. The main question of the essay concerns the aggregative and deliberative qualities of the Malmö initiative and Better Reykjavik, as well as the relationship between aggregation and deliberation. This main question is divided into four subqueries that lead the empirical analysis. These are: (1) Which similarities and differences in terms of design are there between the Malmö initiative and Better Reykjavik? (2) To what extent have these systems mobilized an aggregative political participation? (3) What similarities and differences are there concerning aspects of deliberation? and (4) What is the correlation between aggregation and deliberation like in the two e-petition systems?The method in use is a comparative cross-sectional study with a 'most similar research design'.

NFC is used in many different areas, from subway tickets to authentication systems. This paper presents possible security threats to Near Field Communication and documented attacks that have been used to target various NFC protocols. Weaknesses in different NFC protocols will be presented and suggestions on how to counter certain weaknesses will be discussed. This survey will be valuable for companies interested in protecting their data when using or planning to use NFC systems..
Teknologier för fordonsdiagnostik
The capacity to extract information from vehicles has the potential to be very beneficial. Performing analysis on information about fuel usage, emission values and other driving properties of a vehicle can lead to great economic and environmental benefits.This report contains descriptions of two prominent systems for retrieving information of this nature from a vehicle, On-Board Diagnostics and FMS-Standard, and of an implementation of FMS-Standard.The conclusion drawn after this investigation is that these systems do indeed offer access to the benefits mentioned earlier, although to varying degrees and with differing prioritisation..

SmÄhuset ? val av bergvÀrme, fjÀrrvÀrme eller pellets
This thesis describes the new construction of a small house and it includes studies of three heating systems: geothermal heating, district heating and pellet. The purpose of this thesis is to project a small house which can manage Building Regulations, BBR conditions and then examine three possible heating systems for the small house. This thesis is a literature study which gives an understanding of the heating systems technical structure, properties and costs. An empirical study completes the literature study by giving a deeper understanding of district heating costs and pellet costs. The empirical study contains two interviews, one of which was conducted in a district heating corporation and the other interview was conducted in a pellet corporation.
Faktorer som pÄverkar datakvaliteten hos affÀrs- och DW-system - En fallstudie frÄn en högteknologisk industri
This thesis aims to examine how the quality of data that is entered into and retrieved from a corporate group's ERP and Data Warehouse systems can be improved. The corporate group has already taken several measures that will improve the quality of data. For instance the corporate group has updated and merged the previous ERP systems into one. At the same time the corporate group adjusted the settings in the updated ERP system, so that it will be harder to register incorrect data in the ERP system. With regards to the processes and routines, the studied department has efficient written routines and processes.
Raalie steering systems
Under ht08 och vt09 har vi gjort ett examensarbete dÀr vi i gruppen utvecklat ett mekaniskt styrsystem för sjukhussÀngar. Det nya styrsystem ska underlÀtta det dagliga arbetet för personalen pÄ sjukhusen, dÄ det idag Àr svÄrt att kontrollera sÀngen nÀr man Àr ensam och knuffar. Men med RaaLie fastmonterad pÄ sÀngen kan man utföra arbetet sjÀlv, och det Àr mycket lÀttare att ta sig runt skarpa svÀngar och trÄnga passage..
Informationskrigföring : den nya teknikens hot
The new information society has revolutionised almost the entire world. But the new technique does not only bring good. That which was before only available on paper may today only be available on a computer system. This makes it possible to send data electronically. In the wrong hands that information can become a threat against the security of an individual, a company or even a nation.
Spolmaskangrepp Àr ett ökande problem hos vÀrphöns
This literature review summarizes available data on infection with the parasitic roundworm, Ascaridia galli, as a cause of disease in poultry, including the consequences of a conversion to alternative production systems. Ascaridia galli has a direct life cycle with resistant eggs that survive and are easily spread in the environment, especially in systems with bedding materials where the faecal contact is high. The infection is usually subclinical but depending on the infection dose, the symptoms range from weight loss and diarrhea to mortality. Factors such as the feed composition and genetic variation among different hybrids clearly affect the establishment rate of the infection. Ascaridia galli will probably become an increasing problem, with a shift from the traditional battery cages to alternative systems where the risk of re-infection is high.
Konceptstudie av eltransmission för 8-hjulsdrivet fordon
SEP Modular Armoured Tactical System is the next generation of military vehicles developedby BAE Systems HĂ€gglunds AB. At present time, BAE Systems HĂ€gglunds AB aredeveloping a 6-wheel electrical hybrid and a conventional 8-wheel vehicle. The questionformulation was summarized as: ?In which ways can the electrical transmission in a hybriddriveline for SEP be designed, when the surrounding fixed interfaces are kept and the unity ofcomponents within SEP is maximized??. The purpose of this master thesis was to study avariety of concepts for hybrid propulsion.
Systemen med rÀtt instÀllning - En studie om whistleblowingsystem i Sverige
In order to counteract and to discover unethical actions within an organisation, a growing number of Swedish companies implement a so-called whistleblowing system. The purpose of our essay is to study the mindset of companies and further analyse how this mindset affects the design and quality of companies' whistleblowing systems. To do this, we have used a qualitative approach by interviewing different Swedish companies about their mindsets and systems. The study determines that there seemingly are three different categories of systems of varying quality. In this study we have chosen to call them "internal system", "external system" and "combined system".
Gulliver Simulation - En systemarkitektur f or n atverkssimulering av
Nowadays, a lot of resources are spent on developing systems that will make it possible forvehicles to act autonomously, and make them more effective. One of the projects that isworking on this is the Gulliver Project. Gulliver has constructed a number of miniaturevehicles equipped with various sensors, to use as a physical testbed for autonomousdriving. One big disadvantage with this method is the long iteration time that occursduring the development and testing of a new software.This project has improved this process by developing a system architecture of a virtualtestbed where it is possible to simulate autonomus vehicles that communicates throughany type of wireless network. The testbed has made it possible to simulate autonomusvehicle systems that with a reasonable margin of error, acts like the system would actin a physical test.
