The art to keep in touch: The ''good use'' of Lagrange multipliers

Physically-based modeling for computer animation allows to produce more realistic motions in less time without requiring the expertise of skilled animators. But, a computer animation is not only a numerical simulation based on classical mechanics since it follows a precise story-line. One common way to define aims in an animation is to add geometric constraints. There are several methods to manage these constraints within a physically-based framework. In this paper, we present an algorithm for constraints handling based on Lagrange multipliers. After few remarks on the equations of motion that we use, we present a first algorithm proposed by Platt. We show with a simple example that this method is not reliable. Our contribution consists in improving this algorithm to provide an efficient and robust method to handle simultaneous active constraints.

Victim Support in a Changing Welfare State

This article discusses how new kinds of individual needs develop parallel to the changes in the welfare state. From a study of Victim Service in Sweden it is shown how this organisation has grown parallel to the changes in the welfare state. In the empirical material it is also shown that the need of support often comes from secondary victimisation. Those who are helped by Victim Support are often people with loose bonds to society and people of low class. As victims they can get help from Victim Support, but the need derives from lacking service in the welfare state. NGOs has replaced organisations in the public sector at the same time as the neo-liberal conception of crime, threats and risk has replaced the social democratic ideas of social security.
