Oil rents and domestic price dynamics: evidence from ten OPEC economies

Oil-exporting economies face overlapping domestic price pressures, global energy shocks, and changes in resource income. This study examines relationships among consumer prices, oil rents, and the GDP deflator in ten OPEC economies from 1990-2021, accounting for country differenc...

Intelligent Control of an Autonomous Octorotor Flight Drone Using Image-Based Visual Servoing (IBVS) Under Wind Disturbances

This paper presents a fuzzy-adaptive image-based visual servoing (FAIBVS) command and control system for an octorotor UAV that operates in both wind-disturbed (WD) and nominal circumstances. By combining image-based visual servoing (IBVS) with a fuzzy logic supervisor (FLS), the...

Molecular Hybridization-Guided Design and Synthesis of Novel Pyrazolylidene–Thiazolopyrimidine Derivatives

Abstract The development of hybrid heterocyclic scaffolds represents an effective strategy for expanding the structural diversity of heterocyclic compounds. Herein, we report the synthesis of a new series of pyrazolylidene–thiazolopyrimidine hybrids through a concise and efficien...

An EV-Assisted Dual T-Type Inverter SAPF with Model Predictive Control for Advanced Power Quality Enhancement

In order to improve power quality in low-voltage distribution networks with nonlinear, distorted, and unbalanced loads, this research suggests an innovative design for Shunt Active Power Filters (SAPFs). Compared to conventional single-inverter SAPF structures, the improved metho...

2D-unsteady chaotic flows for mixing two different non-Newtonian fluids: optimization and flow control

Mixing of non-Newtonian fluids has been widely studied, yet numerical investigations of the simultaneous mixing of two different shear-thinning fluids inside chaotic mixers remain limited. In this work, we numerically investigate, for the first time, the mixing of two shear-thinn...
