Effects of ultrasound-assisted freezing on drying kinetics, mass transfer and quality of freeze-dried Abelmoschus sagittifolius root

Freeze-drying is widely recognized as an effective technique for preserving thermolabile medicinal materials. In practice, the long drying period can significantly increase both energy consumption and operating expenses. This study investigated the effects of ultrasound-assisted...

Enhanced FOC performance using a hysteresis current controller for EV induction motor drives

Electric vehicle traction drives require fast, robust, and efficient induction motor control, especially under variable speed, load torque, and thermal operating conditions. In Field-Oriented Control integrated Hysteresis Current Controller (FOC-HCC) induction motor drives, varia...

One-step method for preparation of Fe3O4/g-C3N4 composite using hydrazine for heterogeneous photocatalysis

Environmental pollution and the global energy demand have significantly increased, necessitating sustainable development strategies, with advanced functional materials emerging as key solutions. Specifically, photocatalysis technology has attracted considerable attention due to i...

From gamification to work performance: a two-wave, two-study examination of psychological needs and meaningful work of employees in China and Singapore

Purpose Organisations are increasingly adopting gamification as a strategy to enhance employee motivation, engagement, and performance. While prior research has primarily examined gamification as an organisational tool, this study shifts the focus to how employees experience gami...

Secure and reliable SWIPT in active RIS-aided downlink NOMA with hardware impairments

Abstract Due to growing system complexity and the vulnerability of wireless transmissions to information leakage, maintaining secure and private communication in sixth-generation (6G) networks continues to be a significant problem. By enabling wireless power transfer to distant I...

Deconvolution of cumulative distribution function from repeated measurements with uniform noises

This work is devoted to the estimation of a cumulative distribution function (CDF) using repeated measurements contaminated by additive noise. The noise is assumed to follow a uniform distribution on [−S,S] with an unknown S>0. Since the characteristic function of the noise exhib...
