State Of Art

Clinical applications of Functional Electrical Stimulation (FES) provide both functional and therapeutic benefits. To enhance the functionality of FES systems and to improve the control of the activated muscles through open-loop or feedback controllers, solutions to gather information about the status of the system in real time and to easily detect the intention of the subject have to be optimized. This chapter summarizes the state of art of sensors used in motor neuroprostheses. These sensors can be classified in two categories: sensors of biological signals, such as electromyogram, electroencephalogram, electroneurogram, eye tracking, and voice control, and sensors of non-biological signals, such as sensors of force/pressure (e.g. force sensitive resistors and strain gauges) and sensors of movement (e.g. accelerometers, electrogoniometers, inertial measurement units, and motion capture systems). Definitions, advantages and disadvantages, and some example of applications are reported for each sensor. Finally, guidelines to compare sensors for the design of motor neuroprostheses are drawn.

Abstract: For the control problem of nonlinear discrete systems, this paper describes the status of current research and analyzes the advantages and disadvantages of open-loop and closed-loop iterative learning controller. A class of nonlinear discrete systems will be extended to the general nonlinear discrete systems. To the general nonlinear discrete systems, a open-closed-loop PD-type iterative learning controller which based on current and last output error instead of last output error only is proposed. It makes use of information on system operation more fully and accurately. Besides, based on norm of λ and mathematical induction, its sufficient condition for convergence is given. In order to test its robustness, a simulation is done in the case of a persistent interference. Simulation results show that it is efficient.

Purpose. The purpose of the work is to analyze the application of the second and third parts of Article 3692 of the Criminal Code of Ukraine to officials in the context, that defines them by the Criminal Code of Ukraine in the note to Article 364 of the Criminal Code of Ukraine. Methodology. The methodology includes a comprehensive analysis and synthesis of the available scientific and theoretical material and the formulation of relevant conclusions and recommendations. In the course of the study, the following methods of scientific knowledge were used: terminological, logical-semantic, system-structural, logical-normative. Results: in the course of research the cause of criminalization of such act as "abuse of power" is considered, the subject of the specified criminal act which has the features of "an official" in the context, that defines it by the note to Article 364 of the Criminal Code of Ukraine is analyzed and the main ways of committing criminal acts, that are provided for in this article of the Criminal Code of Ukraine are identified. Originality. The study found, that one of the key conditions for the opportunity to influence officials, that are authorized to perform government or local self-government functions, is the position held by the official and the related opportunities. Therefore, taking into account the opinion of the scientists, that the subject of crimes, that are provided for by the second and third parts of Article 3692 is special, the peculiarities of which is the cumulative feature, that denotes, that such person is not endowed with the status of an official, well-founded need to specify the criminal legislation of Ukraine in terms of the application the second and third parts of Article 3692 of the Criminal code of Ukraine concerning officials in the context, that defines them by the criminal legislation of Ukraine in the note to Article 364 of the Criminal Code of Ukraine. Practical significance. The research results can be used in lawmaking in the improvement of anti-corruption legislation.

This paper presents the comparison of LED driver topologies that include SEPIC, CUK and FLYBACK DC-DC converters. Both topologies are designed for 8W power and operated in discontinuous conduction mode (DCM) with 88 kHz switching frequency. Furthermore, inductors of SEPIC and CUK converters are wounded as coupled. Applications are realized by using SG3524 integrated circuit for open loop and PIC16F877 microcontroller for closed loop. Besides, ACS712 current sensor used to limit maximum LED current for closed loop applications. Finally, SEPIC, CUK and FLYBACK DC-DC LED drivers are compared with respect to LED current, LED voltage, input voltage and current. Also, advantages and disadvantages of all topologies are concluded.

The present paper aims to compare the principles of choosing a marriage partner and analyse the status of being in the marrriage in the frame of family traditions that are totally inherent to the both of the nations: English and Uzbek. It is known that interconnection and cross-cultural communication between the countries of these two nationalities have been recently developed. The purpose to give an idea about these types of family traditions and prevent any misunderstanding that might occur in the communications makes our investigation topical one. The research used phraseological units as an object and the marriage aspects as the subject

The subject of the research is new tools for business financing using the initial coin offering (ICO) in the context of the development of cryptocurrencies and the blockchain technologies as their basis. The purpose of the work was to analyze the advantages and disadvantages of the ICO in comparison with traditional financial tools as well as prospects, limitations and problems of using digital financial tools. Conclusions are made in relation to possibilities, limitations and application areas of digital business financing tools, particularly in the real sector, taking into account the specifics of the Russian economy and legislation. It is shown that the main problems of using the digital financial tools are related to the economic sphere and caused by the lack of adequate approaches to evaluation of assets as well as the shortage of objective information. The problems and new tasks of corporate finance in the digital economy are defined.

Marriage registration is often the subject of discussion among academics in the aspect of legal legitimacy. Is marriage registration a condition of marriage, or the harmony of marriage ?. From all the discourses available, the writer concludes that the recording of marriage in the al-maslahah review is a new witness system, but cannot replace the position of the witnesses who have been introduced and patented in the construction of classical texts and fiqh. its existence is only as complementary, but it is very mandatory to be fulfilled because it impacts on aspects of marriage, both directly and indirectly, such as to the status of the child on a birth certificate, divorce, and other aspects as a result of a marriage, also divorce.

This paper characterises the directions of innovative activities undertaken by food industry enterprises concerning the manufacturing of food products. Based on the subject literature and secondary statistical data, the status of food industry innovativeness and areas of innovative activities related to implementation of technological and non-technological innovations are presented. The activities of enterprises focus on manufacturing new products in response to the ever-changing needs and expectations of consumers. In particular, the production of so-called functional food (which seeks to promote health, minimise the risk of specific diseases, improve psychophysical fitness, lose weight, etc.) is increasingly extensive. Manufacturers must also improve the technologies and techniques of product manufacturing, packaging and storage.

The article presents a comparative analysis of fortification art monuments in such East countries from Ancient Egypt to medieval China. An attempt is made to identify the main stages of the fortification development from a stand-alone fortress (citadel, fort) to the most complex systems of urban and border fortifications, including moats, walls and gates, battle towers. It is shown that the nature of these architectural structures is determined by the status of the city or settlement, its natural landscape, building structures and materials, the development of military and engineering art. The materials from poliorceticon (Greek: poliorketikon, poliorketika), illustrate the main types of siege machines and mechanisms. The advantages and disadvantages of boundary shafts and long walls (limes). The most striking examples are the defensive systems of Assyria, New Babylon, Judea and Ancient China.
