Adaptive Second Order Recursive Terminal Sliding Mode Control for a Four-Wheel Independent Steer-by-Wire System

open access: yesIEEE Access, 2020
An adaptive second order recursive terminal sliding mode (SO-RTSM) is developed for the steering angle control of a four-wheel independent steer-by-wire (4WI-SbW) system.

Pure Second-Order Logic with Second-Order Identity

open access: yesNotre Dame Journal of Formal Logic, 2010
Pure second-order logic is second-order logic without functional or first-order variables. In "Pure Second-Order Logic," Denyer shows that pure second-order logic is compact and that its notion of logical truth is decidable. However, his argument does not extend to pure second-order logic with second-order identity.

Qualitative analysis for a variable delay system of differential equations of second order

open access: yesJournal of Taibah University for Science, 2019
This paper analyzes the stability, uniformly stability, asymptotically stability, boundedness, uniformly boundedness and square integrability of solutions of a system of differential equations of second order with variable delay by applying the direct ...

Continuous Adaptive Finite Reaching Time Control and Second-Order Sliding modes [PDF]

open access: yes, 2013
This paper focuses on the design of adaptive finite reaching time control for first- and second-order dynamic systems with perturbation terms given in a regressive form. The uncertainties considered here are assumed to be bounded with unknown bounds. The

A second order logic of existence [PDF]

open access: yes, 1969
Publisher's, offprint versionA. N. Prior in [9] has suggested an approach towards a second order logic of existence where, following medieval logicians, we distinguish “between predicates (like ‘is red’, ‘is hard’, etc.) which entail existence, and ...

A note on phase-lag computations for multiderivative methods for second order periodic initial value problems [PDF]

open access: yes, 1985
Phase—lag computations are carried out for a family of two-step multiderivative methods for solving second order initial value problems of the form y" = f(t,y), y(t0) = y0, y'(t0) = z0.

Augmented human intelligence goes beyond the AGI mirage

open access: yesDiscover Artificial Intelligence
This paper argues that contemporary Artificial General Intelligence (AGI) approaches face significant challenges that make Augmented Human Intelligence (AHI) a more promising and practically beneficial alternative.

Second order Zeeman interaction and ferroquadrupolar order in TmVO4

open access: yesnpj Quantum Materials, 2022
TmVO4 exhibits ferroquadrupolar order of the Tm 4f electronic orbitals at low temperatures, and is a model system for Ising nematicity. A magnetic field oriented along the c-axis constitutes a transverse effective field for the quadrupolar order ...

Second-Order Reversed Phi [PDF]

open access: yesPerception & Psychophysics, 1999
Abstract A second-order reversed-phi stimulus is composed of moving features (areas filled with texture) whose overall amount of texture-contrast is reversed between successive frames. In peripheral vision, the stimulus is perceived as moving in the reversed direction (opposite to the feature displacement).
