Abstract: The study concerned an optical tissue absorption sensor which, if applied at the chest as a novel region, offers a non-disturbing multiparametric monitoring of all three: cardiac activity, respiratory activity, and changes of the oxyhemoglobin saturation S. Contrary to the standard region (e.g., finger), the chest region yields the respiration activity and accelerated assessment of S, though restricted to relative changes. As a novelty, the mutual interrelations between the respiratory activity and …light absorption are discussed. The non-distal sensor could be combined with indispensable thoracic sensors, making distal oxygen sensor redundant if the determination of changes of S is sufficient. Show more

Abstract: The design of mold temperature control strategies (MTCS) is a challenging multi-objective optimization task which demands for advanced optimization methods. Evolutionary algorithms (EA) are powerful stochastically driven search techniques. In this paper an EA is applied to a multi-objective problem using aggregation. The performance of the evolutionary search can be improved using systematic parameter adaptation. The DACE technique (design and analysis of computer experiments) is used to find good MOEA (multi-objective evolutionary …algorithm) parameter settings to get improved solutions of the MTCS problem. SPO (sequential parameter optimization), i.e., an automatic and integrated approach, which extends DACE, is applied to find the statistically significant and most promising EA parameters. Show more

Abstract: Multi-channel electrodes are implanted in various regions in man for different medical purposes. Operating in a constant mode most of them surprise by simple stimulation strategies. For example single channel epidural stimulation of the spinal cord allows switching from tonic muscle output to a rhythmic stepping like pattern only by changing the stimulation frequency. However, speech understanding with cochlear implant needs sophisticated processing which can be done by a miniaturized computer behind the patient's …ear. Even more complex stimulation patterns are desirable for electrode arrays of retina implants. Show more

Abstract: Previous studies demonstrated that visual stimuli activate auditory cortex in deaf subjects [1,2]. In this paper, we used electroencephalography (EEG) in hearing subjects to evaluate whether auditory cortex comes to serve the visual modality after visual/auditory training. In the perceptual feedback training, the hearing subjects were trained to relate certain visual sources to particular sound sources. In the results, we found that visual activity was observed in the auditory cortex when only the visual stimuli were …given to the subjects and feedback training improved the subjects' ability to associate visual actions with particular sound sources.

Abstract: An approach based on an evolutionary algorithm for the Hysteretic Preisach model identification is presented. The proposed Symbiotic Evolutionary Algorithm is based on a synergy between Genetic Algorithm and Bacterial Chemotaxis Algorithm. The synergy allows to perform more accuracy on numerical results and more numerical stability versus the use of a single algorithm. The proposed approach has been validated by experimental hysteresis loops.

Abstract: This paper proposes an evolutionary learning acquisition method of the trajectory of a rotary crane for the residual vibration reduction by use of the dynamic analysis of the rotary crane and the genetic algorithm. The rotary crane is driven by only the rotational motion of a boom. In the design of the evolutionary learning acquisition system, the equation of motion of the rotary crane is obtained, and the trajectory of the rotational angle of the boom is …depicted with sixth-order polynomials. Then, considering the boundary and constraint conditions, the trajectory are expressed by two genes. Solving the equation of motion of the load corresponding to the trajectory of the boom, the residual vibrations of the load are computed as a function of the chromosome with the two genes, and a fitness function of the genetic algorithm for the residual vibration reduction of the load is defined. Furthermore, the evolutionary learning acquisition algorithm of the trajectory of the boom for the residual vibration reduction of the load is constructed. Moreover, it is confirmed numerically and experimentally that the residual vibrations of the load can be extremely reduced by the present evolutionary learning acquisition method. Show more

Abstract: Until now, Ultrasonic Motor (USM) have been designed by using some simple analytic equations or the trial and error method. Therefore, existent design methods of the USM have the problems such as the inaccuracy and the inefficiency. For the solution of these problems, we propose the optimal design methodology of a USM by using the Evolution Strategy (ES) and the Finite Element Method (FEM). The L1B4 USM is designed optimally by using proposed optimal design methodology.
