This paper presents an energy relaxation-based approach for the modeling of single crystalline magnetic shape memor)) alloy response under general two-dimensional magnetomechanical loading. It relies on concepts of energy relaxation in the context of non-convex free energy landscapes whose wells define preferred states of straining and magnetization. The constrained theory of magnetoelasticity dev

Field study of evacuation upwards long stairs, ascending evacuation, in two different buildings, 48 meters and 109 meters high. Measuring walking speed along the stair slope and vertical speed. Presenting values for different percentiles of the studied population. The importance of not using the same value for walking speed for different stairs since the design of the stairs has a strong impact, a

In this paper we will investigate the different algebraic varieties and ideals that can be generated from multiple view geometry with uncalibrated cameras. The natural descriptor, Vn, is the image of p3 in P2×p2×...×p2 under n different projections. However, we will show that Vn is not a variety. Another descriptor, the variety Vb, is generated by all bilinear forms between pairs of views and cons

In this article I examine whether an influential theory of mechanisms proposed by Peter Machamer, Lindley Darden and Carl Craver can accommodate polygenic effects. This theory is both interesting and problematic, I will argue, because it ascribes a central role to activities. In it, activities are needed not only to constitute mechanisms but also to perform their causal role. These putative functi

There is today a lack of clinical techniques for detecting acute hypotension during conventional hemodialysis treat -ment, despite the fact that hypotension remains the - mosr common acute complication during hemodialysis. Hypotension is often followed by nausea, vomiting, and even fainting, not only strenuous for the patient but requires considerable attention from the nursing staf. The problem o

We consider the problem of stochastic control under power constraints. Problems such as linear quadratic optimal control with information constraints are instances of the problem considered. The calculations of the optimal control law can be done off-line as in the classical linear quadratic Gaussian control theory using dynamic programming, which turns out to be a special case of the new theory d

In the paper we address traffic engineering problems related to optimization of routing in IP networks applying destination-based shortest path routing (SPR) of the OSPF type. An SPR routing pattern is determined by a system of (administrative) weights defined over the set of IP links: the routes for IP forwarding are determined as the shortest paths computed locally at the nodes using the current
