In this paper, a new method for dynamic balancing of double four-bar crank slider mechanism by metaheuristic-based optimization algorithms is proposed. For this purpose, a proper objective function which is necessary for balancing of this mechanism and corresponding constraints has been obtained by dynamic modeling of the mechanism. Then PSO, ABC, BGA and HGAPSO algorithms have been applied for...

The paper reveals the essence of administrative and legal support for activities Bar Ukraine. Different approaches to understanding category “administrative support” are considered. activity bar is defined as state-authorized subjects regulated by norms law, which aimed at creating conditions providing guarantees proper functioning bar. features this definition highlighted, namely: one types la...

Sorghum seedling transplanting is an essential agricultural activity in Sub-Saharan Africa. However, conventional manual of sorghum a time-consuming, labour-intensive, costly with low rate, uneven plant distribution, and degree accuracy. In order to realize rapid precise seedlings transplanting, duckbill-type mechanism has been designed. This five-bar linkage consisting two crankshafts, connect...

Implant-supported craniofacial prostheses are made to restore defective areas in the face and cranium. This clinical report describes a technique for fabrication of an orbital prosthesis with three adjacent implants in the left lateral orbital rim of a 60-year-old woman. Selection of appropriate attachment system (individual magnetic abutments versus bar-clip attachment) for implant-supported o...
