Higher-order chain rule for differential forms is used to obtain the (higher-order) moments of a random matrix from certain cumulants and vice versa. computer algorithms are written for the above chain rule. In particular, computer algorithms for finding moments and cumulants of normal and Wishart random matrices are obtained. (C) 2000 Elsevier Science B.V. All rights reserved.

The complexity of modern anesthesia procedures requires the development of decision-support systems functioning in a smart-alarm capacity. We developed computer algorithms to detect critical conditions during surgery (light anesthesia or unstable blood pressure), based on computerized anesthesia records containing hemodynamic data (heart rate, mean arterial pressure and systolic arterial pressure). Our analysis indicated that a ≥12% change in mean arterial blood pressure (MAP), compared with the median value of MAP over the preceding 10-min interval, may be chosen as the criterion for detecting LA, with a sensitivity of 96% and a specificity of 91%. The best agreement between human and computer ratings of blood pressure lability (correlation coefficient 0.78) was achieved when we used the absolute value of the fractional change of the mean arterial pressure (|FCM|) between one 2-min epoch and the next 2-min epoch. Work is under progress to develop a decision-support system to alert clinicians in the operating room environment to critical events.

In order to support education in distributed system fundamentals and to elucidate the function of distributed algorithms and protocols, we apply animations of formal models which concentrate on the mediation of aspects of the dynamic system behavior. For this purpose we adapted and extended approaches and tools supporting the animation of sequential algorithms. Besides sets of special animations, the results comprise a set of view types providing for the convenient presentation of dynamic properties. Furthermore, we report on experiences we gained from a series of corresponding educational experiments.

We apply the spatially and temporally periodic boundary conditions devised by Kraynik and Reinelt (Int. J. Multiphase Flow 18 (1992) 1045) to an atomic fluid undergoing planar elongational flow and describe several algorithms which efficiently apply the required nonstandard periodic boundary conditions. These periodic boundary conditions guarantee unrestricted simulation times, and are simply implemented if a rotational transformation is first applied to the coordinates of all atoms such that one of the cell boundaries aligns with the direction of elongation. While in the transformed frame one can apply either Lagrangian rhomboid (LR) or "deforming brick" (DB) periodic boundary conditions to all particle coordinates and relative distances. The latter (DB) scheme turns out to be very similar in form to standard Lees-Edwards periodic boundary conditions for planar shear flow, and both the LR and DB schemes are shown to be equivalent and numerically highly efficient.

Conducting polypyrrole/polyaniline colloidal composites have been prepared by deposition of the solution mixture of polypyrrole and polyaniline at negative potentials. Different substrates were dipped in the solution containing the mixture together with acrylic latex and after drying the adhesive strength and electroactivity of the paint were studied. Several colloidal composite based coatings were investigated. At last a computer facilitated with powerful artificial neural network based algorithms classified the paints.

A general two-phase coordinated planning and control algorithm is developed to determine optimal motions among obstacles and dynamic objects in a shared environment. The algorithm consists of a two-phase approach: planning a global path for each object subject to the constraints of the workspace and then locally optimizing along each global path to minimize some process dependent cost function. The order in which objects are planned will also affect the overall performance of the system. The algorithm is applied to a simulated surface-mount assembly system. The results show an improvement over other planning and control methods.
