An effective strategy to predict the remaining useful life (RUL) of a cutting tool could maximise utilisation, optimise machining cost, and improve quality. In this paper, novel approach, which is enabled by hybrid CNN-LSTM (convolutional neural network-long short-term memory network) model with an embedded transfer learning mechanism, designed for predicting RUL tool. The innovative characteri...

Nanoparticle (<100 nm size) exposure in workplaces is a major concern because of the potential impact on human health. National Institute for Occupational Safety and Health (NIOSH)-approved particulate respirators are recommended for protection against nanoparticles based on their filtration efficiency at sealed conditions. Concerns have been raised on the lack of information for face seal leak...

Medicinal and pesticidal plant propagation is hampered by poor seed germination due to dormancy. This study aimed enhance seedling growth using various pre-sowing treatments. A triplicated two-factor experiment in a Randomized Complete Block design was used. Soaking water at 25&deg;C for 24 h (T1), soaking 60&deg;C hot 10 min (T2), ppm Potassium nitrate (KNO3) treatment (T3), 20 (T4), Treating ...

In current times, noise pollution is especially apparent in urban areas due to rapid development transportation, industrialization, and urbanization. The worsening detrimental human health behaviour as it can contribute disorders psychological disturbance. Thus, regulation crucial must be addressed with immediate effect. Micro-perforated panels (MPP) a potential solution mitigate on commercial ...

Photovoltaic (PV) systems-based energy generation is relatively easy to install, even at a large scale, because it scalable in size and thus transport. Harnessing maximum power only possible if tracking (MPPT) functionality available as part of the converter control that interfaces PV panels grid. Solar exposure covering all unlikely happen time, which known partial shading (PS) phenomenon. As ...

In recent years, metamaterial-structures and Microperforated panel (MPP) absorbers have been proposed as a valid alternative to porous materials for sound absorption in the low frequency range. However, high broadband cannot be achieved range required some engineering applications where large thicknesses of are unsuitable. this work, deep subwavelength hybrid parallel-arranged MPP Archimedean-i...

This paper presents new findings on partial discharge (PD) phenomena under high-repetition nanosecond pulsed voltages, essential for the insulation design of electrical motors fed by silicon carbide (SiC) inverters with high-switching frequencies. Here, a twisted pair sample simulating turn-to-turn random-wound motor coil winding was subjected to voltages generated SiC inverter-based pulse gene...
