During polymer melt extrusion from a circular nozzle, the extrudate at low flow rate shows a stable linear shape with smooth surface but the extrudate at higher flow rate shows unstable shapes with spiral, rosary, or zig-zag structures.This phenomenon is known as melt fracture and hampers high throughput production in polymer processing.For linear
A micro-energy harvesting device proposed in the literature was numerically studied.It consists of two bluff bodies in a micro-channel and tumbler skins a flexible diaphragm at its upper wall.Vortex shedding behind bodies induces pressure fluctuation causing vibration of the diaphragm that converts mechanical energy to electrical by means of a piez
The aim of an article.The purpose of the study is to prove the necessity of forming a national brand strategy for economic development of Ukraine.The results of the analysis.Search an effective solution of economic crisis in Ukraine requires the use of innovative approaches to the choice of strategy development, economic management mechanism, integ
In the 3-D space, this paper implements vehicle convoy and curash water wipes 6x80 interception by using guidance strategy.Based on the differential equations for the range, the pitch angle and the yaw angle between successive vehicles, the deviated pursuit and the proportional navigation are proposed to derive decentralized control strategy for ve
This study aims to analyze and obtain empirical evidence that budget participation affects budgetary slack.Another objective is to prove that good governance and organizational commitment can weaken the effect of budget participation on budgetary slack.This study is quantitative.The population of the study was all Regional Apparatus Organizations (
