Robotics with exoskeletons has opened a new era of research in the field of modern rehabilitation and assistive technologies. The technology promises to improve the functionality of the upper limbs, which are necessary for daily operations. Exoskeleton technology is developing rapidly but requires interdisciplinary research to solve technical problems such as kinematic compatibility and the development of effective human-robot interaction. This article presents a new design of a device that helps to rehabilitate the upper extremities. The proposed design is characterized by a lightweight structure with an adaptable geometry for various users with low cost and easy to wear characteristics. The CAD model is developed for design details and for modeling, the results of which provide data on the feasibility of the proposed design and its characteristics in the main operational characteristics.

The development of technologies for the use of renewable energy sources, especially wind energy, has so far reached a level that allows them to compete with standard energy sources even without the help of economic incentives, such as "green" tariff. Today there are many programs for assessing the effectiveness of wind turbines for a particular area. In this paper analyzes the wind flow by modeling the proposed location of the wind turbine. The object of study was a hilly area with a maximum height of about 720 meters. Using the WindSim software environment, a scale is drawn and such important parameters as wind rose, wind profile, turbulence are analyzed. This study gives the possibility of possible problems associated with the climatic conditions of the selected area. The program uses a simplified model estimate of the wind flow, which allows wind statistics to local conditions of the possible location of wind energy capacities. To solve this problem, it is assumed that that air is an incompressible medium, air the flow is turbulent, and the effect of the Coriolis forces is negligible compared to the force’s friction of air on the underlying surface. in this work, a neutral stratification of the atmosphere over the area under consideration is assumed.
