Abstract The present work aims at the application of different optimization strategies in the electromagnetic analysis of the Variable Reluctance Motor (VRM) through Finite Element (FE) simulation. Two case studies are i...

Weed species present high competitive capacity, rapid adaptability and herbicide resistance, hindering their effective control across worldwide cropping regions. Since field-conducted experiments are very time-consuming ...

The study explores modulation disks as high-precision optical sensors for measuring angular positions and rotational velocities, crucial for industrial and military use. Laser ablation is employed to refine microstructur...

Unbalanced field length exists when ASDA and TODA are not equal. Airport authority may add less expensive substitutes to runway full-strength pavement in the form of stopways and/or clearways to basic TORA to increase op...

Abstract In this study, aluminium (Al) matrix composites reinforced with 0, 5, and 10 vol% silicon carbide (SiC) particles were fabricated by direct hot-pressing under 35 MPa pressure at 600 °C for a holding time of 5...

Abstract The study proposes a multidimensional mathematical modeling of antennas using coaxial cables for 5G, with emphasis on the relationship between cable length, frequency, and VSWR. By employing a final configuratio...

Abstract Given the global lack of effective analysis methods for the impact of design parameter tolerance on performance deviation in the vehicle proof-of-concept stage, it is difficult to decompose performance tolerance...

ObjectiveAiming at the problem that the gear transmission system of aero-engines is prone to traveling wave resonance under complex operating conditions, which further restricts high-reliability lightweight design, a vib...

Abstract The research on surface texture is developing from single macro-texture to composite micro-nano texture. The current research on the anti-friction mechanism and theoretical models of textures is relatively weak....

Abstract Topology Optimization (TO) is a powerful numerical technique to determine the optimal material layout in a design domain, which has accepted considerable developments in recent years. The classic Finite Element ...

The determination of trends and prediction of stock prices is one of the main tasks of the MACD (Moving Average Convergence Divergence) and the RVI (Relative Volatility Index) indicators of the technical analysis. The re...

Abstract To improve the design speed and reduce the design cost for the previous blade design method, a modified inverse design method is presented. In the new method, after a series of physical and mathematical simplifi...
