Energy Science &Engineering, EarlyView.ABSTRACT This attempt examines the heat transfer enhancement from unsteady bioconvective Maxwell nanofluid flow under the incidence of solar radiation influenced by viscous dissipation and chemical reaction through a porous medium. The nanofluid contains silver and titanium alloy hybrid nanoparticles with gyrotactic micro‐organisms in ethylene glycol ...

Two‐timescale design for RIS‐aided full‐duplex MIMO systems with transceiver hardware impairments
IET Communications, Volume 17, Issue 1, Page 98-109, January 2023., 2023 Abstract This paper focuses on a reconfigurable intelligent surface (RIS)‐aided full‐duplex multi‐user massive multiple‐input multiple‐output system with transceiver hardware impairments (THWIs). Different from the existing works, the two‐timescale design scheme is considered. The phase shift at the RIS is designed only based on the statistical channel

Krichever-Novikov Vertex Algebras on Compact Riemann Surfaces [PDF]
arXiv, 2015 We give a notation of Krichever-Novikov vertex algebras on compact Riemann surfaces which is a bit weaker, but quite similar to vertex algebras. As example, we construct Krichever-Novikov vertex algebras of generalized Heisenberg algebras on arbitrary compact Riemann surfaces, which are reduced to be Heisenberg vertex algebra when restricted on Riemann

A High‐Order Hybrid‐Spectral Incompressible Navier–Stokes Model for Non‐Linear Water Waves
International Journal for Numerical Methods in Fluids, EarlyView.We present a high‐order accurate CFD model for simulating nonlinear water waves using the incompressible Navier–Stokes equations. The model employs a combined Chebyshev–Fourier basis for efficient spatial discretization, and a low‐storage fourth‐order Runge–Kutta method for temporal integration. A Poisson pressure problem is solved using a geometric p$$

Sampled‐data synchronization of singular Markovian jump system: Application to DC motor model
IET Cyber-Physical Systems: Theory &Applications, Volume 7, Issue 4, Page 171-182, December 2022., 2022 Sampled‐data synchronization problem for singular Markovian jump systems (SMJSs) subject to aperiodic sampled‐data control is investigated. The validity of these approaches is demonstrated by a DC motor model. It also demonstrated that the two‐sided LBLF method possesses a larger upper bound of sampled‐data period than the one‐sided LBLF method ...

Laurent phenomenon algebras arising from surfaces II: Laminated surfaces [PDF]
arXiv, 2018 It was shown by Fock, Goncharov and Fomin, Shapiro, Thurston that some cluster algebras arise from triangulated orientable suraces. Subsequently Dupont and Palesi generalised this construction to include unpunctured non-orientable surfaces, giving birth to quasi-cluster algebras.

Dissipativity‐based adaptive integral sliding mode control of Takagi‐Sugeno fuzzy descriptor systems
IET Control Theory &Applications, Volume 17, Issue 1, Page 53-73, January 2023., 2023 Abstract This paper focuses on the problem of adaptive integral sliding mode control (ISMC) with dissipativity for a type of complex non‐linear system represented by Takagi‐Sugeno (T‐S) fuzzy descriptor models. First, T‐S fuzzy descriptor systems with different derivative matrices are transformed into augmented systems that have the same properties as ...

Deformed Hyperkähler Structure for K3 Surfaces [PDF]
arXiv, 2002 We apply the method of algebraic deformation to N-tuple of algebraic K3 surfaces. When N=3, we show that the deformed triplet of algebraic K3 surfaces exhibits a deformed hyperk\"{a}hler structure. The deformation moduli space of this family of noncommutatively deformed K3 surfaces turns out to be of dimension 57, which is three times of that of ...

A Learning Model with Memory in the Financial Markets
International Journal of Finance &Economics, EarlyView.ABSTRACT Learning is central to a financial agent's aspiration to gain persistent strategic advantage in asset value maximisation. The implicit mechanism that transforms this aspiration into an observed value gain is the speed of error corrections (demonstrating, an agent's speed of learning) whilst facing increased uncertainty.
