Modeling induced flow anisotropy and phase transformations in air hardening steels.

In this work a material model for hardening development in sheet metals during forming processes involving loading path changes is formulated. In particular, such hardening development is due to the formation and interaction of dislocation microstructures in the material, resulting in an evolution in the size, center and shape of the yield surface. Such yield surface evolution is accounted for in

Hazardous Materials Incidents - Some Key Results of a Risk Analysis

Human safety and health, environmental and property protection and security concerning hazardous materials supply chain are important issues for many countries, industries and organisations around the world. This paper presents some key results of a comprehensive risk study on hazardous materials supply chain incidents. Based on a risk analysis framework adapted for mari-time transport of packaged

Capturing better data: The potential for better insight into user's requirements through iterative prototyping

This article aims at introducing to a wider circle a complementary research approach in user oriented work. Its most fundamental part is the use of technology as a tool for capturing the needs, wishes and dreams of a user. The incitement for us to start developing this method was an experience based, serious, questioning of conventional methods such as interviews, questionnaires, etc, and their c

Heart Failure Management in the Elderly. Focus on Health Economics and Quality of Life

The incidence and prevalence of heart failure (HF) has increased successively over the past decade. Mortality and morbidity is high. It is the most common cause of hospitalisation in the elderly and has been estimated to account for 1-3% of health care costs in many countries. There is a need therefore, to improve care for HF patients. However, due to limited economic resources, this must be done
