Expert system to calculate the cofficient of friction : an approach to enhance traffic safety

Friction plays a key role in causing slipperiness as a low coefficient of friction on the road may result in slippery and hazardous conditions. Analyzing the strong relation between friction and accident risk on winter roads is a difficult task. Many weather forecasting organizations use a variety of standard and bespoke methods to predict the coefficient of friction on roads. This article proposes an approach to predict the extent of slipperiness by building and testing an expert system. It estimates the coefficient of friction on winter roads in the province of Dalarna, Sweden using the prevailing weather conditions as a basis. Weather data from the road weather information system, Sweden (RWIS) was used. The focus of the project was to use the expert system as a part of a major project in VITSA, within the domain of intelligent transport systems

Corporal Punishment : A study about attitudes and opinions to corporal punishment and the connection to children’s rights in South Africa and Sweden

Corporal punishment is a worldwide problem. The purpose withthis thesis is to promote a constructive discussion about the problem andconnect this to children’s rights. This gives the possibility to start adiscussion about suggestions and measures to reduce the problem. Thetheory is that corporal punishment is used as a disciplinary method tochange behavior. Children’s rights is regulated by conventions and nationallaws. The method is to conduct an analysis with interpretations andcommentaries of the research materials from South Africa and Sweden.The conclusion is that those who are positive to corporal punishment thinksit is an efficient working method, and it is about children’s safety. Thosewho are negative have experienced that alternative methods works. Asuggestion is to involve children in the work with children’s rights andeducate them in human and children’s rights with focus on obligations andresponsibility.
