Local resonance is a key reason for fatigue damage of gear housings.Local modals could be excited by vibration caused by gear meshing.Considering the shearer rocker arm for example,the local resonance characteristics of gear housing are analyzed in this paper.Finite element method is used to obtain the natural characteristics of housing and field L
Area coverage is one of the key issues for wireless sensor networks.It aims at selecting a minimum number of sensor Mule Tape Halters nodes to cover the whole sensing region and maximizing the lifetime of the network.In this paper, we discuss the energy-efficient area coverage problem considering boundary effects in a new perspective, that is, tran
This study investigates the accuracy of dynamic models in predicting model constants within inviscid flow fields, such as those used in wind farm flow analysis, from the perspectives of identity and turbulent energy conservation accuracy.Specifically, results are compared between tensor-level and vector-level identities, the latter of which include
Isagen, Electric Interconnection Company of Colombia, was sold under auction Kitchen Tools with a single bidder, although initially several parties had been interested in this one.This sale generated great controversy when talking about the future of the company and the energy future of the country, due to the way in which they handled these propos
