Improvement of digital human models

In a design process major decisions are often taken at an early phase, i.e. at the CAD screen. In order to consider ergonomics in a proper way, a designer then needs a valid human model (digital manikin). The paper describes several experiments that were done to improve human models

Postural behaviour in static reaching sidewards

This paper describes postural behaviour in static reaching sidewards, and the role of the trunk in particular. It turned out that the trunk (chest, pelvis) is not involved when reaching sidewards up to roughly 40-50°(depending on the reach distance). At greater angles the arm, the chest, and the pelvis each contribute at a particular rate to get the index finger onto target. These rates are reasonably similar to the average contributions of the arm, chest, and pelvis to the total of the range of motions of the arm, chest, and pelvis, suggesting that these segments share the musculoskeletal load equally.

Three ways to show 3D fluid flow

Visualizing 3D fluid flow fields presents a challenge to scientific visualization, mainly because no natural visual representation of 3D vector fields exists. We can readily recognize geometric objects, color, and texture: unfortunately for computational fluid dynamics (CFD) researchers, vector fields are harder to grasp. Thus, we must construct simplified representations that human observers can understand. Simplification means focusing on relevant aspects of the flow. This offers many options, making a wide variety of flow visualization techniques both feasible and desirable. This article presents an overview of three different visualization techniques developed in the Netherlands. The three useful techniques for visualizing 3D flows are: implicit stream surfaces, turbulent particle animation, and a flow probe
