The paper proposes a new method for implementing the parallel multidigit subtraction. The paper provides an analysis on the basis of which it is possible to predict carry signs between words and between groups of words into which multidigit numbers are split on the substracting. The analysis is presented in the form of a lemma. The paper presents an iterative bitwise operation for correcting carry signs for each word in a group of words. An algorithm for implementation the substraction operation using k processors is proposed.

Laughter and smiling are significant facial expressions used in human to human communication. We present a computational model for the generation of facial expressions associated with laughter and smiling in order to facilitate the synthesis of such facial expressions in virtual characters. In addition, a new method to reproduce these types of laughter is proposed and validated using databases of generic and specific facial smile expressions. In particular, a proprietary database of laugh and smile expressions is also presented. This database lists the different types of classified and generated laughs presented in this work. The generated expressions are validated through a user study with 71 subjects, which concluded that the virtual character expressions built using the presented model are perceptually acceptable in quality and facial expression fidelity. Finally, for generalization purposes, an additional analysis shows that the results are independent of the type of virtual character’s appearance.

The Individual

We present a new method to measure workload that offers several advantages. First, it uses non-intrusive means: cameras and a mouse. Second, the workload is measured in real-time. Third, the setup is comparably cheap: the cameras and sensors are off-the-shelf components. Fourth, we go beyond measuring performance and demonstrate that just using such measures does not suffice to measure workload. Fifth, by using a Bayesian Network to assess the workload from the various manifesting measures the model adapts itself to the individual user as well as to a particular task. Sixth, we use a cognitive computational model to explain the cognitive mechanisms that cause the differences in workload and performance.

The probabilistic methods are used in engineering tasks where a computational model contains random variables. The new method the Direct Optimised Probabilistic Calculation (DOProC) - which is being developed now seems to be highly efficient in terms of calculation time and accuracy of solution. The computation is purely numerical and does not use any simulation techniques. The algorithm has been implemented in several software applications which have been used in probabilistic tasks and probabilistic reliability assessments.

Investigations which require electron microscope examination of a few specific areas of non-homogeneous tissues make random sampling of small blocks an inefficient and unrewarding procedure. Therefore, several investigators have devised methods which allow obtaining sample blocks for electron microscopy from region of tissue previously identified by light microscopy of present here techniques which make possible: 1) sampling tissue for electron microscopy from selected areas previously identified by light microscopy of relatively large pieces of tissue; 2) dehydration and embedding large numbers of individually identified blocks while keeping each one separate; 3) a new method of maintaining specific orientation of blocks during embedding; 4) special light microscopic staining or fluorescent procedures and electron microscopy on immediately adjacent small areas of tissue.
