Voice over IP (VoIP) is a relatively new technology that enables voice calls over data networks.With VoIP it is possible to lower expenses, and increase functionality and flexibility. FromSwedish Armed Forces point of view, the security issue is of great importance, why the focus inthis report is on the security aspect of the two most common open-source VoIP-protocols H.323and SIP, some of the most common attacks, and counter-measures for those attacks.Because of the level of complexity with a network running H.323 or SIP, and the fact that it hasyet to stand the same level of trial as of traditional telephony, a VoIP-system includes manyknown security-issues, and probably at present many unknown security flaws.The conclusion is that it takes great knowledge and insight about a VoIP-network based onH.323 or SIP to make the network satisfyingly safe as it is today, and is therefore perhaps not asuitable solution for the Swedish Armed Forces today for their more sensitive communications..

This is a degree project performed at Halmstad University in Sweden on the subject carpet ofreinforcement. This project is developed in association with Celsa Steel Service in Halmstad.The purpose of this report is to investigate how much time that can be saved if carpet ofreinforcement is used instead of the traditional way to work with reinforcement and seewhat kind of parameters that is important between the choices. We are also going to seehow this product affects the situation for reinforcement workers from an ergonomic point ofview.Carpet of reinforcement is made by straight reinforcement?s bars that are welded togetherwith steel bands. These rolls are made at a factory with a machine that welds together thebars in determined centre distance, with desired dimensions after the constructionengineers? blueprints.

The emphasize of this study is to evaluate security issues for home users having a personal computer connected to the Internet. It focus on the usage of advantages and disadvantages when using a firewall while connected to the Internet. The hypothesis is that it gives a better protection to install and use a firewall compared not to do so, due to security flaws in the operating system. The prediction was tested on a home user's personal computer. The testwork was divided into two major tests, each of them performed with, respectively without, a firewall. These major tests were divided into five smaller semi­ tests. The first semi­test without a firewall suffered from a virus or worm attack resulting in loss of data and log files.

AbstractThis essay analyse, from a normative perspective, what can be exspected of an etical asylum policy. The theorical base is derived from Gerard Delanty´s notion of civil cosmopolitism.The ethical outlook is based on utilitarianism. The questions this essay answers are:1) Which are the basic premises for an ethical asylum policy?2) Does the Swedish asylum policy forfill these premises?The study analyses in general terms the Swedish asylum policy. It analyses both the asylum law and the work of the executive authority.The analyse also includes a brief look at two asylum cases.

A unified model of stress and affect consciousness was proposed. The connection between affect consciousness and perceived stress was studied. Teachers (n = 19) were interviewed using Monsens affect interview, followed one month later by a questionnaire containing Perceived Stress Scale (PSS), State-Trait Anxiety Inventory (STAI-S, STAI-T) and Twenty Item Toronto Alexithymia Scale (TAS-20).Statistical analysis showed no connections between level of total affect consciousness and perceived stress. Though there were some indications of a negative relationship between affect consciousness and trait anxiety. There were also indications, using a complementary analysis, of a connection between level of affect consciousness on the subscale distress in the interview and perceived stress.

Scania provides a fleet management system for hauliers who want to control their fleets in anefficient way. The system includes an onboard computer with touch screen called ScaniaInteractor where the driver can access GPS navigation, order support, message service and otherfunctionalities. The purpose of this thesis is to develop a concept for logging the user interactionon the Interactor and analyze the result which enables further development and optimization ofthe interface.A demonstration application is designed, implemented and tested for the purpose of showing thepossibilities and difficulties with logging of interaction. The result shows that logging is quiteeasy to implement and that the amount of produced data is small and therefore not expensive totransfer via GPRS to a central server where searching and analysis can be done. On the otherhand, the biggest challenge lies in the analysis and interpretation of the logged data and to applyit to the development of the interface.

In this thesis, it is investigated if it is possible to create a common factor of the work tasks done by an air traffic controller, which then can measure workload. This will lead to the development of a tool to measure workload at small airports. In the research project a questionnaire is created to measure the different tasks an air traffic controller has. The same questionnaire will also measure the number of environmental factors that exists around the air traffic controller. To measure the validity of the questionnaire, the authors are using NASA-TLX.

Men abuse women every day. It has become a Health Problem which we affects all of us. Help is available for those women who have the strength to seek it. Health care personnel are often these women?s only contact with the surrounding world.

This thesis is based on an assignment from a unit within an international group manufacturing industrial products. The purpose of the thesis is to analyze and suggest ways to improve the cost accounting system in use at the unit. The main source of empirical data has been interviews with employees. The theoretical framework is based on a comparison between traditional/standard costing and activity-based costing (ABC). The cost accounting system in use is described in detail and classified as a traditional/standard cost accounting system.

The purpose of this thesis is to analyze and propose improvements to the current procedure for cost estimations of purchased maintenance work at Banverket, the Swedish rail administration. This governmental institution is responsible for the procurement of maintenance services for the country?s railroad network through open tenders. Due to the generally low number of contractors, it is particularly necessary to establish accurate cost estimates in order to assess the offers and ensure that a fair price is being paid to the suppliers. Several flaws associated with the current practice are identified and analyzed according to cost accounting theories.

Denna uppsats undersöker huruvida den dramaturgiska strukturen är en förutsättning för att en situationskomedi ska fungera väl ? det vill säga, vara underhållande och locka till skratt. I en komparativ analys av den mycket väl fungerande amerikanska situationskomedin Friends och den mindre bra svenska situationskomedin Svensson, Svensson framkom dock inga större strukturella brister hos något av analysobjekten. Följaktligen är inte den dramaturgiska strukturen avgörande för slutresultatets förmåga att roa. The aim of this study is to find out if dramatic structure is essential to the sitcom's ability to entertain and make audiences laugh. This study is a comparative analysis of the more humorous American situation comedy Friends and the less humorous Swedish situation comedy Svensson, Svensson.

This thesis evaluates the user board of the elememtary school in Veberöd, Sweden. In this process an evaluation model is developed. The model itself gets evaluated in a meta-evaluation to improve the model for future use.The starting point of the evaluation is the deliberative democracy theory. Although Sweden is a representative democracy an official desire exists to have a democracy with deliberative qualities. The evaluation model is constructed to fit this context and is therefore, not only, set out from classical goal-based evaluation but also from deliberative democratic evaluation.

The rural development programme is a tool for promoting sustainable development in the Swedish countryside. The master plan should, for example, give directions for the national interest and describe how it will follow up national and regional targets such as the EU's environmental quality standards. Because the municipality has considerable freedom to formulate the plan in its sole discretion, and that it contains the municipality's political vision, it is also feasible to make a discourse analysis of the plan text.In discourse analysis, including articles and documents written by Rural Network Working Group on land use planning to be included. The purpose of discourse analysis is to see if there are differences in the way rural areas are described and if there are any flaws in how the designer interprets the rural development programme. Furthermore, the analysis result in tools that are adapted to the standards we create and choose.The standards we have are being designed based on our values, which differ.

In 2010 Swedish political parties used commercials broadcasted on TV for the first time in order to gain votes in a general election. In connection with the election the parties were criticized for not succeeding to formulate a story to the voters that conveyed how they wanted to change Sweden. In this paper I use central concepts from rhetoric, storytelling, postmodernism and psychology to formulate three demands each on the narrator, the story and its reception. Using the resulting image of what distinguishes a good narrator, a good story and a good reception as a starting point, I investigate to what extent the critique was justified. My findings indicate that the degree to which the commercials fulfill these demands vary greatly.
