experimental investigation on double-impulse

PRINCIPLES OF HEAT TRANSFER MODELLING USING

An important issue in the experimental heat transfer investigation of ribbed channels is the adopted measuring flow pattern produced by transverse vortex generators was visualized using a planar beam of double-impulse laser tailored by a cylindrical lens and oil particles Sequential images of the particles in a cross sectional plane taken with

The situation when the critical double impulse inputs into the irregular shaped building structure in the worst direction is defined as the worst-case situation in this paper These difficulties were caused by various factors especially delay of current investigation procedure of earthquake-damaged houses The experimental parameters

Double impulse tests of long airgaps Part 3: Voltage

Withstand voltage ratings for air insulation are partly based on test data obtained with standard biexponential impulses The importance of the time parameters of the test impulse with the distinction between lightning (LI) and switching (SI) standard impulses is well established The paper (Part 3) describes tests on a 6 m rod-plane gap with stresses which depart substantially from the

1 Introduction

Based on a set of independent modal equations obtained by adopting modal approach the double-impulse control with reverse direction is proposed which is aiming at not only suppressing vibration but also avoiding the variation of the equilibrium position of the boom system after active control action And the characteristic of time-lag

A brief history of bullshit: Why we've learned to ignore

Sep 14 2019That is the more scientific knowledge develops the more it becomes – bizarrely and ironically – fuzzy and unreliable at least to the public Think also of the "replicability crisis" that plagues the experimental sciences Scientists have not been able to replicate 70 percent of existing psychology experiments some of them very well

Research on Satellite Formation Establishing in Elliptical

In order to solving the establishment problem of satellites formation establishing in elliptical orbits the problem of Lambert transfer based on two-impulse control with unfixed time and initial position is studied The Niche Genetic Algorithms (NGA) is used to locating the optimal transfer orbit and the transfer time and initial position are coded into genetic algorithms as well as the

double impulse welding: The purpose of the double impulse welding cycle is that the first impulse (shorter) will soften the material and allow for belter surface contact at the welding spot The second impulse (usually longer) will finish the weld and will completely fuse the welded materials

Momentum Change and Impulse

A force acting upon an object for some duration of time results in an impulse The quantity impulse is calculated by multiplying force and time Impulses cause objects to change their momentum And finally the impulse an object experiences is equal to the momentum change that results from it

Escapement

An escapement is a mechanical linkage in mechanical watches and clocks that gives impulses to the timekeeping element and periodically releases the gear train to move forward advancing the clock's hands The impulse action transfers energy to the clock's timekeeping element (usually a pendulum or balance wheel) to replace the energy lost to friction during its cycle and keep the timekeeper
