This study explores the structural, electronic, mechanical, optical, and photovoltaic properties of Ca₃PBr₃ anti-perovskite derivative material using DFT SCAPS-1D simulations. Results confirm its high stability through tolerance factor...
This study investigates the structural, electronic, mechanical, and optical properties of perovskites Mg3AsX3 (X = F, Cl, Br, I) using DFT SCAPS-1D. The tolerance factor shows that these materials are thermodynamically stable. Furthermore, Mg3AsF3, Mg3AsCl3, Mg3AsBr3, Mg3AsI3 exhibit direct bandgaps 3.48, 2.06, 1.26, 0.265 eV, respectively, confirming their semiconducting nature. Mg3AsBr3 stands out for its ductility excellent properties, such as a high dielectric constant good conductivity,...
The solar sector is shifting towards lead-free, inorganic cubic halide perovskites due to their superior structural, electronic, and optoelectronic properties. This study uses density functional theory (DFT) examine the optical properties of X
The application of a feedback linearization technique using artificial neural networks (ANNs) for nonlinear industrial process plant is considered in this paper. modeled first an ANN, and then the dynamic network model acting as emulator linearized. A novel configuration ANN only backpropagation used. Effective control linearized exhibited linear controller. Experimentation simulation results on are presented to demonstrate effectiveness technique.
This paper tries to represent the difference between single diode and two photovoltaic models in terms of efficiency simulated by MATLAB. The research activities done earlier had shown a clear preview that solar cell can act as concentrated for increasing conversion great extant so output power be improved large scale. Here showing manner action double model has been calculated observing comparison with convenient one. It observed module is highly efficient model. And this treated convert...
An electromagnet and a float are needed to be designed for magnetic suspension system.In this paper an optimized design of is being carried out based on minimum flux leakage maximum amount force that can imparted the float.This also compares different designs find advantages disadvantages these designs.Design starts from simple naïve then gradually improved until satisfactory obtained.Different shapes floats were considered optimum float.Electromagnetic analysis with commercial FEM (Finite...
Home automation has become an integral part of our daily lives and evolved since inception to bring feasibility compatibility homes workplaces. The basic foundation home is the ability control lights, fans, kitchen utensils, etc., automatically. Google Home, Amazon Echo, Apple Kit are most widely used systems. This document will build a voice-enabled project that both efficient cost-effective. Using WI-FI IOT, it can be remotely controlled monitored using Android device. We use sustainable...
The main contribution of the paper is to provide an explicit necessary and sufficient conditions for system be locally linearisable in terms parameters heat exchanger model. Examples illustrate how controllability issues which are standard linear theory can naturally extended nonlinear model via linearising transformation.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
It is well-known that an artificial agent exhibits deterministic dynamics when it moves in a closed real world environment. interesting to determine this biological being such as fish kept environment and free move it. This paper determines some of motion freely moving The task divided into several stages — image capturing, processing, time series extraction, Chaos analysis Classification. classification performance analyzed with feed forward neural network (FNN), Recurrent Neural network,...
Frequency deviations and inter-area tie-power fluctuations from their respective scheduled values following a local load disturbance which is source of great concern in interconnected power system operation control.

Software driven solutions are limited to the amount of memory size and storage capacity, but sizes databases increasing every day. Hence, now a day, handling data accessing it in an acceptable time is one biggest challenges especially large database system. In database, records can be categorized according access frequencies; some very frequently accessed (hot data), hardly (cold data) other occasionally (warm data). conventional we keep all hot, warm cold single database. case record...
The regular utilization of web-based applications is crucial in our everyday life. Model View Controller (MVC) architecture serves as a structured programming design that developers utilize to create user interfaces. This pattern commonly applied by application software construct applications. use MVC framework PHP Scripting language often essential for development.
