IETO: An Improved Exponential–Trigonometric Optimisation Algorithm for Dynamic 3D UAV Trajectory Planning

IET Networks, Volume 15, Issue 1, January/December 2026.
This paper proposes an improved Exponential–Trigonometric Optimisation algorithm for dynamic 3D UAV trajectory planning in cluttered and uncertain environments. By integrating optimised Latin hypercube sampling, adaptive exploration–exploitation control and probabilistic local refinement, the method improves search robustness, convergence stability and

Grounded Series and Parallel RL/RC Immittance Simulators Using a Single Second‐Generation Voltage Conveyor

Journal of Engineering, Volume 2026, Issue 1, 2026.
This work proposes the active simulation of grounded series and parallel resistive‐inductive (RL) and resistive‐capacitive (RC) immittance functions employing a single second‐generation voltage conveyor (VCII) and three passive components. The two configurations are designed for series RL and RC immittance simulation and RL and parallel RC immittance ...

Fault Diagnosis of Variable Load Bearing Based on Quantum Chaotic Fruit Fly VMD and Variational RVM

Shock and Vibration, Volume 2019, Issue 1, 2019., 2019
Under normal circumstances, bearings generally run under variable loading conditions. Under such conditions, the vibration signals of the bearing malfunctions are often nonstationary signals, which are difficult to process effectively. In order to accurately and effectively diagnose the failure types and damage degree of bearings under variable load ...

A Versatile Cell of Multimode First‐Order Universal Filter Using VCIIs

Journal of Electrical and Computer Engineering, Volume 2025, Issue 1, 2025.
This article presents a new generic core cell for designing the first‐order universal filter employed second‐generation voltage conveyor (VCII+). With appropriate admittance selection, the proposed core cell can derive four different filter types, namely, low‐pass, high‐pass, inverting all‐pass, and noninverting all‐pass functions and encompassing four

Multiphase sinusoidal oscillator using the CFOA pole [PDF]

IEE Proceedings - Circuits, Devices and Systems, 1995
A multiphase sinusoidal oscillator using the parasitic poles of current feedback operational amplifiers (CFOAs) is presented. The oscillator can generate n signals which are equal in amplitude and equally spaced in phase. The oscillator using the parasitic poles of CFOAs is suitable for high frequency applications and monolithic IC fabrication.
