An Advanced Study on Two Stroke Internal Combustion Engine to Enhance Clean Combustion by the Improved Method of the Airflow

Posted on May 31, 2021Categories EngineeringTags , , , ,   Leave a comment on An Advanced Study on Two Stroke Internal Combustion Engine to Enhance Clean Combustion by the Improved Method of the Airflow

The goal of this project is to build a new model of two-stroke spark-ignition engine in order to decrease scavenging issues. This style permits fresh air to enter the cylinder through intake valves at the bottom and burned gases to depart through exhaust ports at the top. As the piston pulls towards the bottom of the cylinder, the exhaust ports close, and the fuel is pumped. As a result, the chances of fuel and exhaust gases combining are reduced. Due … Continue reading “An Advanced Study on Two Stroke Internal Combustion Engine to Enhance Clean Combustion by the Improved Method of the Airflow”

Research on Interband Optical Transitions in Gd2O3: Er Nanoparticles – Prospective System for Energy Convertors

Posted on May 31, 2021Categories EngineeringTags , ,   Leave a comment on Research on Interband Optical Transitions in Gd2O3: Er Nanoparticles – Prospective System for Energy Convertors

In Gd2O3 nanoparticles doped with Er3+ ions at 0.25-8 mol percent concentration, the properties of electron transitions in the region of fundamental absorption edge, as well as vibrational characteristics, are examined. For cases of direct and indirect interband transitions, initial reflection data is analysed. The related energy gaps are shown to be dependent on activator concentration. The effect of a large decrease in phonon frequency when a matrix is doped with a modest amount of Er3+ is discovered. The information … Continue reading “Research on Interband Optical Transitions in Gd2O3: Er Nanoparticles – Prospective System for Energy Convertors”

Model Reduction Method based on Rational Canonical Form of System Matrix and Krylov Subspace: A Scientific Explanation

Posted on May 31, 2021Categories EngineeringTags , , ,   Leave a comment on Model Reduction Method based on Rational Canonical Form of System Matrix and Krylov Subspace: A Scientific Explanation

The rational canonical form of the system matrix and the Krylov subspace are used to propose a new projection approach for obtaining simplified models for single input and single output time-invariant linear systems. Using linear transformation, the system matrix is first changed to its rational canonical form. The model is subsequently reduced using both the projection approach and the Krylov subspace approach. The advantage of this strategy is that the reduced system’s poles are identical to those of the original … Continue reading “Model Reduction Method based on Rational Canonical Form of System Matrix and Krylov Subspace: A Scientific Explanation”

In most cases, a seismic hazard analysis is carried out for a location in an active seismicity region. In a low-to-moderate region like East Malaysia, such an examination is rarely carried out. The seismic hazard analysis procedure necessitates the application of a suitable ground motion prediction equation, or GMPE, to estimate ground motion intensity. The research calculates peak ground acceleration (PGA) as a function of earthquake magnitude and distance. The characteristics of low-to-moderate databases were employed in this study, and … Continue reading “Peak Ground Acceleration of East Malaysia Based on a Proposed Ground Motion Prediction Equation”
