Knock Recognition System in a PCCI Engine Powered by Diesel

Highlights in Science, Engineering and Technology, 2022
The measurement of engine vibrations components is used to identify combustion phases in a single-cylinder PCCI diesel engine in this work. A single channel Knock transducer was used to measure engine vibration caused by combustion pressure forces and knocking tendency.

A robust optimal distributed control design for simultaneous voltage regulation and current sharing in DC microgrid

IET Smart Grid, Volume 6, Issue 6, Page 653-665, December 2023., 2023
In this paper, a robust optimal distributed controller is designed for achieving average voltage regulation and current sharing in a DC microgrid. The proposed controller is formed such that the possible estimation error is considered as an uncertain parameter.

Material characterisation for optical wireless communication combining measurement and Monte Carlo simulations

IET Optoelectronics, Volume 17, Issue 4, Page 149-161, August 2023., 2023
This paper proposes a method for optical characterisation of materials, which is a very important input for realistic channel simulation based on Ray‐Tracing Monte‐Carlo algorithms. This original approach consists first in carrying out some measurements of the optical power received after propagation in the environment containing the materials sought ...

Building local decision‐making competencies during COVID‐19: Accelerating the transition from learning healthcare systems to learning health communities

Learning Health Systems, Volume 7, Issue 2, April 2023., 2023
Abstract Introduction The persisting and evolving COVID‐19 pandemic has made apparent that no singular policy of mitigation at a regional, national or global level has achieved satisfactory and universally acceptable results. In the United States, carefully planned and executed pandemic policies have been neither effective nor popular and COVID‐19 risk

Consensus based target tracking against deception jamming in distributed radar networks

IET Radar, Sonar &Navigation, Volume 17, Issue 4, Page 683-700, April 2023., 2023
In this paper, a data‐level anti‐deception jamming target tracking algorithm is proposed for distributed radar network by exploiting the spatial position differences between physical and false targets. Through numerical simulations, the effectiveness of the algorithm is verified, where both the collaborative and non‐collaborative false targets can be ...

Effect of Pilot Injection with Various Starts of Second Injection Command (SOIC2) and Fuel Injection Pressures on Gasoline Compression Ignition Combustion

International Journal of Energy Research, Volume 2023, Issue 1, 2023., 2023
This experimental study was conducted using a single‐cylinder compression ignition (CI) engine with a pilot injection strategy to determine the effect of fuel injection pressure and the timing of the second start of injection (SOI2) on combustion and emission characteristics.
