The Problem of Adhesion Methods and Locomotion Mechanism Development for Wall-Climbing Robots

This review considers a problem in the development of mobile robot adhesion methods with vertical surfaces and the appropriate locomotion mechanism design. The evolution of adhesion methods for wall-climbing robots (based on friction, magnetic forces, air pressure, electrostatic adhesion, molecular forces, rheological properties of fluids and their combinations) and their locomotion principles (wheeled, tracked, walking, sliding framed and hybrid) is studied. Wall-climbing robots are classified according to the applications, adhesion methods and locomotion mechanisms. The advantages and disadvantages of various adhesion methods and locomotion mechanisms are analyzed in terms of mobility, noiselessness, autonomy and energy efficiency. Focus is placed on the physical and technical aspects of the adhesion methods and the possibility of combining adhesion and locomotion methods

The Study of Sound Symbolism Based on Phonosemantic Association Experiment With the Vowels of the Ukrainian Language

The research deals with the relationship between sound symbolism and the theory of natural origin of the language.There is a certainassociation between particular sound sequences and different meanings in speech. But such a definition of sound-meaningdoes not explain fully the properties of wordsnot only to represent some meaning but also deal with perception caused by different sounds. It is important to demonstrate this mechanism in theory and practiceto examine correspondence between sounds and the meanings the sounds are associated with. Scholars have studied onomatopoeiaand inner meaning of words in different languages since ancient time. Most of their lexical-semantic explorations are devoted to the correlation between sounding and meaning of short onomatopoeic words on the basis of the statistical review. Chronology of the sound semantic explorations in linguistics, philosophy and psychologyis analyzed in the article with a detailed description of experimental studies. The scientific methods used to study associations arising between the proposed colors and Ukrainian sound-letters are as follows: psycholinguistic, mathematical, descriptive, inductive and method of semantic differential. The analysis of the data received finds out the presence of a sound symbolic component in all the vowels of the Ukrainian language and the correspondence of a certain color to each examined sound-letter. The term ‘sound-letter’ is first used in psycholinguistics and is determined as a unit of speech, realized in a text which forms the speaker’s certain mental image. The conclusions made on the basis of this research confirm the interconnection betweensounding, speech perception, general perception, and the speaker’s individual comprehension. Further study is needed to justify sound symbolism of vowels in different positions of short words, through series of practical experiments with a larger number of speakers

International justice as a way to settle conflicts in the world arena : the idea and the implementation

The purpose of this article is to identify the processes regarding the emergence of international justice and the start of international courts functioning. Dialectical, phenomenological and historical methods of analysis is the methodological basis of the article to allow to identify the international justice essence and the specifics of this phenomenon implementation in the initial stages of its development. In the course of this analysis the authors came to the conclusion that the international justice concept formation occurred in the turn of the XIXth and XXth centuries while the international justice formation took place in the first half of the XXth century.peer-reviewe

Integration of economic shifts in the european development in the second half of the XXth century

Purpose: The article analyzes those processes having initiated the development of the European and political integration. The article is focused on the genesis and the development of the Council for Mutual Economic Assistance, the European Union, NATO and the Warsaw Pact. Design/Methodology/Approach: By applying the system analysis method as well as dialectical and historical methods, the authors have attempted to reveal the significance of those events resulted in modern international organizations establishment. Findings: Authors have analyzed the XX century trends in integration and highlighted Western Europe as the most productive in the process. Authors have provided the USSR and post-USSR integration overview to reveal the European development patterns. Practical Implications: The research results may be implemented into political and educational courses as well as to be used by official authorities. Originality/Value: The main contribution of this study is the deep integration trends'analysis and the emphasis on the unipolar-bipolar-multipolar world's concept.peer-reviewe
