The thermal stress of molecular sieve adsorption tower under transient temperature 40-290°C is the basis for ensuring safe operation tower. In this paper, based on thermodynamics theory, finite element model full-size established. distribution at key positions body analyzed, and strength maximum equivalent position evaluated. results show that residual corner inner wall opening to take over imp...

It is hypothesized that structured sliding-surfaces improve the lubrication condition by forming an oil sump on sliding surface, redistributing oil, and trapping wear debris. For these reasons, have been used as a friction reduction method for long time. In this work, effects of microstructure laid cylinder liner internal combustion engine twin-land control ring (TLOCR) piston skirt were invest...

This paper proposes a dual-polarized filtering antenna with extracted-pole unit (EPU) using LTCC substrate. The EPU realizes the high skirt characteristic of bandpass filter transmission zeros (TZs) located near passband without cross coupling. is designed and fabricated in 28 GHz band for 5G Band-n257 (26.5-29.5 GHz). measured S11 less than -10.6 dB Band-n257, isolation between two ports dual ...

This paper presents an evaluation of the electric field criticality and potential distribution in a chain 69 kV glass insulators. The analysis was performed under different operating conditions: insulators with cement reduction, sacrificial ring, bell touching pollution effect. For this, multhiphysics simulation software used. As results, it noted that reduction ring presence intensified fields...

Ghosting artifact in the field of image stitching is a common problem and the elimination of it is not an easy task. In this paper, we propose an intuitive technique according to a stitching line based on a novel energy map which is essentially a combination of gradient map which indicates the presence of structures and prominence map which determines the attractiveness of a region. We consider...
