Because of the pitch rate for the different amplitude of the sinus wave, flow deflection angle δ, pivot position, and the Mach numbers, this paper presents the influence of curved leading edges on the damping derivative. Results show that there is a gradual rise in the pitch damping derivatives from h = 0 with the […]

The article describes a complex method of design, in situ visualisation and control of the surface treatment process widely used: the process of gas nitriding. As a result, the possibilities of poly-optimization and poly-parametric simulations of the direction of the process were obtained, together with a visualisation of the value changes of the time function […]

The approach to system identification is a data-driven approach that constructs a mathematical system model that has been widely applied to astronomy, automatic control, economics and society. Currently, in the field of biomedical engineering, device recognition is widely used. The behaviour of the system is defined by a series of procedures in which the chemical […]

This study introduces an integrated hybrid cooling, heating and power (RES-CCHP) system for renewable energy sources, powered by a biogas-fueled internal combustion engine ( ICE) and photovoltaic ( PV) panels, distinct from the conventional CCHP system for natural gas. Renewable energy sources (RES) exploration is an important way of resolving the energy and environmental crisis, […]

This work focuses on the extraction of harmonic current and the compensation of reactive power using the shunt active power philtre (SAPF). An algorithm based on (ADALINE) Neural Network and Real and Imaginary Instantaneous Forces (ANN-RIIP) is designed to extract and classify harmonic components in order to achieve this goal. In addition, this algorithm independently […]

For incremental static analysis of a collection of inter-colliding particles, simulating 2D flow, a simple method is suggested. Numerical experiments show that the proposed approach converges to a final equilibrium state if the liquid is confined within the borders of a collection of inter-communicating vessels. As a first approximation to the 2D motion of a […]

With major facilities such as sports complex, educational institutions , hospitals, flyovers, multiplex halls, etc., Guwahati, the main town in the North Eastern region of India, is growing rapidly in every aspect. In order to ensure the structural protection and serviceability of the above-mentioned structures before any building, awareness of the subsurface soil conditions is […]

The objective of this current work was to carry out biological synthesis and characterization of gold nanoparticles ( AuNPs) using plant extracts using environmentally friendly technology: cactus (Opuntia sp.), onion (Allum sp.), pear (Pyrus sp.), coffee (Coffea sp.) and laurel (Laurus sp.), as reducing agents and stabilisers. Normal methodologies have been obtained. Maximum absorbance at […]

The goal of the research was to study the composite obtained from silicon carbide, silicon and refractory clay mixture in an impure nitrogen medium. The chemical processes of burning of the aforementioned mixture in the technical nitrogen medium and the form of binder obtained, phase composition and basic properties are studied with X-ray diffraction, petrographic […]

This paper reports on 3C-SiC low-doped drain power MOSFET design and simulation, including key parameters such as the model of avalanche effect ionisation and its relationship to breakdown voltage, the doping dependence of bulk mobility, and the relationship between on-resistance and breakdown voltage. While scaling the parasitic JFET, a number of MOSFETs were built with […]
