Reliability allocation has an essential connection to design for reliability and is an important activity in the product design and development process. In determining the reliability of subsystems or components on the basis of goal reliability, attention must be paid to failure effect, failure information, and improvement opportunities based upon real potentials for reliability improvement. In...

The paper discusses the use of combined control for a system two parallel pumps to increase its service life. Using control, pumping is controlled together by change speed, throttling, and bypass. power consumption calculated three methods flow control: with minimum energy consumption, maximum reliability, trade-off between efficiency reliability. In case higher than in 29.2%. proposed which pr...

In this paper, the effect of the Intake Valve Deactivation (IVDA) on engine performance is investigated in detail. Based on an optimization platform with Genetic Algorithm (GA) and engine thermodynamic model, the characteristics of the engine volumetric efficiency and pumping loss were studied under the cam-drive, Single Intake Valve (SIV) and Dual Intake Valves (DIV) operating modes, and the e...

Cell based microassays allow the screening of a multitude of culture conditions in parallel, which can be used for various applications from drug screening to fundamental cell biology research. Tubeless microfluidic devices based on passive pumping are a step towards accessible high throughput microassays, however they are vulnerable to evaporation. In addition to volume loss, evaporation can l...

We have numerically studied a non-adiabatic charge transport in the quantum Hall system pumped by a magnetic flux, as one of the simplest theoretical realizations of nonadiabatic Thouless pumping. In the adiabatic limit, a pumped charge is quantized, known as Laughlin’s argument in a cylindrical lattice. In a uniform electric field, we obtained a formula connecting quantized pumping in the adia...
