In this study, a newly developed test set-up installed in a thermal vacuum chamber and the thermal performance test performed with this set-up is described.Evaporator is simulated by using mounted resistive heaters on it whereas two black painted aluminum plates in contact with the condenser are used to remove heat from heat pipe.Thanks to the vacu
ObjectiveIn response to challenges such as large sampling data, extended diagnosis time, and subjective fault feature selection in traditional bearing fault diagnosis, a CS-DMKELM intelligent diagnosis model for rolling bearings is proposed based on compressed sensing(CS) and deep multi-kernel extreme learning machine(D-MKELM) theory.MethodsFirstly
BackgroundDuring health disaster events such as the current devastating havoc being inflicted on countries globally by the SARS-CoV-19 pandemic, mental health problems among survivors and frontline workers are likely concerns.However, during such health disaster events, stakeholders tend to give more precedence to the socio-economic and biomedical
Low speed and high angle of attack are problems that must be faced in vertical launching missiles.A natural asymmetric vortex phenomenon occurs at a low speed and high angle of attack of a slender body.In this paper, the Detached Eddy Simulation (DES) method is adopted to simulate the asymmetric flow of a slender body at a high angle of attack.The
