In this paper, we generalize the Boltzmann–Hamel equations for nonholonomic mechanics to a form suited for the kinematic or dynamic optimal control of mechanical systems subject to nonholonomic constraints. In solving these equations one is able to eliminate the controls and compute the optimal trajectory from a set of coupled first-order differential equations with boundary values. By using an...

Background. The No Return Point hypothesis is one of the research areas that has been done in line with the motor program. In this hypothesis emphasized an inability to inhibition move after its start by the motor program. Several factors are affecting the mechanism of this inhibition. Objectives. In this study, we investigate the effects of audio and visual stimuli on blocking quick moves to ...

Mosquitoes are important living organisms that participate in the different levels of food chains. However, many families include vector species capable to transmit viruses, bacteria and parasites both humans animals, threatening public health. The goal this work was describe biological diversity mosquito areas M'sila; Algeria based on ecological nature their habitat. breeding sites found were ...

We consider a nonlocal semi-linear parabolic equation on connected exterior domain of the form $${\mathbb {R}}^N\setminus K$$ , where $$K\subset {\mathbb {R}}^N$$ is compact “obstacle”. The model we study motivated by applications in biology and takes into account long range dispersal events that may be anisotropic depending how given population perceives environment. To formulate this meaningf...

The article is devoted to the study of various aspects formation innovative strategies for economic development regions. authors presented several variants definitions innovation strategy, essentially compared and analyzed them. Various approaches definition concept strategy were considered, including G. Hamel K.K. Prahalada, M.Yu. Porter, C. Macmillan, M.Mescon A. Chandlenr, on their basis aut...
