PID‐Like Robust Control of Non‐Minimum Phase Robotic Manipulators

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper proposes an output‐feedback tracking controller for non‐minimum phase nonlinear systems with unknown uncertainties and external disturbances, where not all states are measurable, and the zero dynamics are unstable. The approach combines a backstepping‐based stabilizing state‐feedback law with a cascade extended high‐gain observer ...

FinTech and Environmental Sustainability: Evidence From Brazil

Sustainable Development, EarlyView.
ABSTRACT This study explores the dynamic interplay between economic growth and environmental sustainability from a FinTech perspective, using Brazil as a case study. While FinTech's contribution to green transformation, sustainable finance, and resource efficiency has gained increasing attention, a notable lack of empirical research remains to assess ...

Dynamical property of interaction solutions to the Chafee-Infante equation via NMSE method

Heliyon
In this work, we study the Chafee-Infante model with conformable fractional derivative. This model describes the energy balance between equator and pole of solar system, which transmit energy via heat diffusion. To explore the multi soliton solutions and

Are human‐altered landscapes reshaping carnivore niche spaces in the Trans‐Himalaya?

Wildlife Biology, EarlyView.
Understanding carnivore interactions under growing human pressures is crucial for conservation. We examined spatial and temporal niche structuring among snow leopards Panthera uncia, Himalayan wolves Canis lupus chanco, and red foxes Vulpes vulpes; while also incorporating free‐ranging dogs Canis lupus familiaris as a human‐subsidized mesopredator ...

Bio‐Inspired Optimisation Methods Applied to Low Carbon Power and Energy Problems: A Survey

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Bio‐inspired optimisation methods have been widely applied to complex real‐world problems, particularly in low‐carbon power and energy systems, where optimisation tasks often involve high‐dimensional, constrained and mixed‐integer characteristics.

The Extended Weierstrass Transformation Method for the Biswas–Arshed Equation with Beta Time Derivative

Fractal and Fractional
In this article, exact solutions of the Biswas–Arshed equation are obtained using the extended Weierstrass transformation method (EWTM). This method is widely used in solid-state physics, electrodynamics, and mathematical physics, and it yields exact ...

A solution procedure for behavior of thick plates on a nonlinear foundation and postbuckling behavior of long plates [PDF]

Approximate solutions for three nonlinear orthotropic plate problems are presented: (1) a thick plate attached to a pad having nonlinear material properties which, in turn, is attached to a substructure which is then deformed; (2) a long plate loaded in ...

Recognition of Spatiotemporal Feature Images of Zero‐Sequence Voltage for Single‐Phase High‐Impedance Ground Faults Under Complex Conditions

High Voltage, EarlyView.
ABSTRACT Diagnosing high‐impedance ground faults (HIGFs) in distribution networks is extremely challenging because high transition resistance significantly reduces electrical signal strength and unpredictable initial fault phase angles coupled with asymmetric voltage disturbances often lead to misclassification.

Investigation of optical soliton solutions for the fractional-order nonlinear Schrödinger equation including parabolic law of nonlinearity

Boundary Value Problems
The optical soliton solutions for the fractional-order nonlinear Schrödinger equation with parabolic law are investigated in the present study. The analysis employs conformable fractional derivatives, beta derivatives, and truncated M-fractional ...

Edge Sharpness Does Not Vary Between Palaeolithic Flake Technologies, With the Possible Exception of Levallois Débitage

Archaeometry, EarlyView.
ABSTRACT Investigating why hominins adopted particular flake technologies during the Mid‐to‐Late Pleistocene is essential to understanding patterns of lithic innovation. This period witnessed the emergence of Levallois technologies (~350–250 ka) and later blades, each “replacing” earlier forms.
