A 31 L multilevel inverter topology with less switching devices for hybrid electric vehicle applications.

In this article, a 12 switch 31 L multi-level inverter (MLI) is proposed with the benefits of least switching devices for electric vehicle applications. In most electric vehicles (EV), conventional inverters are utilized so the lifetime of electric vehicle induction motors is reduced due to the high THD level and high voltage stress. To rectify this, a new inverter topology is proposed with minimum switching devices by increasing the level to 31, and also the THD should be maintained within IEEE standards.

Synthesis, characterization, quantum mechanical calculations and biomedical docking studies on curcumin analogs: 2, 6-(Difurfurylidene) cyclohexanone and 2, 6 - Bis (2,6-Dichloro Benzylidene) Cyclohexanone.

The initiation of colorectal cancer is controlled by various factors, including random occurrences and genetic alterations affecting oncogenes and tumor suppressor genes.Curcumin, a significant compound extracted from turmeric, has attracted interest for its robust anticancer properties, particularly regarding its analogs, 2, 6-bisdifurfurylidene cyclohexanone (DFC) and 2, 6-bis (2, 6-dichlorobenzylidene) cyclohexanone (DCC), which were synthesized and assessed for their anticancer efficacy. A combination of spectroscopic techniques and molecular docking methods was utilized to comprehensively evaluate the interaction behaviors of DFC and DCC.

The experiment was carried out in the solar still with and without integration at four different water masses within the basin, and metrics such as water, glass, basin temperature, and drinkable water generated were measured. The results showed that the daily distillate collected from the integrated system using 2.

COVID-19: Machine learning for safe transportation.

Entire world has been affected by Covid-19 pandemic. In fighting against the Covid-19, social distancing and face mask have a paramount role in freezing the spread of the disease. People are asked to limit their interactions with each other, to reduce the spread of the disease.

A machine learning approach to identify hand actions from single-channel sEMG signals.

Surface Electromyographic (sEMG) signal is a prime source of information to activate prosthetic hand such that it is able to restore a few basic hand actions of amputee, making it suitable for rehabilitation. In this work, a non-invasive single channel sEMG amplifier is developed that captures sEMG signal for three typical hand actions from the lower elbow muscles of able bodied subjects and amputees. The recorded sEMG signal detrends and has frequencies other than active frequencies.

Efficient catalytic activity of BiVO nanostructures by crystal facet regulation for environmental remediation.

Controlled growth of BiVO nanostructures along (121) and (040) crystal facets plays a crucial role in enhancing their catalytic performance. In this regard, the visible light active photocatalyst BiVO was synthesized concerning the effect of pH and surfactants by hydrothermal method. The morphology and size of BiVO are strongly dependent on the concentration of H and Bi in the reaction system while varying the pH.

Frailty Analysis of SEMG Signals for Different Hand Movements Based on Temporal and Spectral Approach.

Surface electromyography (sEMG) signal is the electrical manifestation of neuromuscular activities. It is an intricate signal that depends on the anatomical and physiological properties of the contracting muscles beneath the skin. In this work, a single channel surface EMG amplifier is designed to acquire the signals non-invasively from the skin by using bio-potential electrodes for three different hand movements.
