The pattern of degenerative joint disease (DJD) of the intervertebral and apophyseal joints of the vertebral column of 81 skeletons from the thirteenth to fourteenth century medieval priory cemetery of St. Andrew, Fishergate, York, was recorded in relation to their location of interment: eastern cemetery, southern cemetery, and intramurally (within the priory buildings). Archaeological context ...

We study the empirical meaning of randomness with respect to a family of probability distributions Pθ, where θ is a real parameter, using algorithmic randomness theory. In the case when for a computable probability distribution Pθ an effectively strongly consistent estimate exists, we show that the Levin’s a priory semicomputable semimeasure of the set of all Pθ-random sequences is positive if ...

This paper addresses the problem of real-time generation of near-optimal control for nonlinear plants. It advocates using the direct method of calculus of variations based on a priory approximation of the optimal solution by appropriate reference functions depending on several variable parameters and then applying inverse dynamics to determine the corresponding controls. The paper reviews gener...

In this article, we study the new streamline diffusion finite element for treating the linear second order hyperbolic initial-boundary value problem. We prove a posteriori $ L^2(L^2)$ and error estimates for this method under minimal regularity hypothesis. Test problem of an application of the wave equation in the laser is presented to verify the efficiency and accuracy of the method.

Vision is a crucial sensor. It provides a very rich collection of information about our environment. The difficulty in vision arises, since this information is not obvious in the image, it has to be constructed. Wheres earlier approaches have favored a bottom-up approach, which maps the image onto an internal representation of the world, more recent approaches search for alternatives and develo...

Robotized laser welding is an application, which requires high speed combined with high precision. Realistic Dynamic Simulations combined with Off-line Programming, significantly enhances the a priory prediction of the weldability of a specific product. Obviously, realistic dynamic simulations require realistic models of the robot and controller. A 3DOF robot model has been formulated which inc...
