The Geothermal Artificial Intelligence for geothermal exploration
(Pergamon-Elsevier Science Ltd, 2022)
Exploration of geothermal resources involves analysis and management of a large number of uncertainties, which makes investment and operations decisions challenging. Remote Sensing (RS), Machine Learning (ML) and Artificial ...
Tulczyjew's triplet with an Ehresmann connection I: Trivialization and reduction
(World Scientific Publ Co Pte Ltd, 2023)
We study the trivialization and the reduction of Tulczyjew's triplet, in the presence of a symmetry and an Ehresmann connection associated to it. We thus establish a geometric pathway for the Legendre transformations on ...
Minimum Length Scheduling for Discrete-Rate Full-Duplex Wireless Powered Communication Networks
(IEEE-Inst Electrical Electronics Engineers Inc, 2022)
Wireless powered communication networks (WPCNs) will act as a major enabler of massive machine type communications (MTCs), which is a major service domain for 5G and beyond systems. The MTC networks will be deployed by ...
Invariant manifolds of homoclinic orbits and the dynamical consequences of a super-homoclinic: A case study in R4 with Z2-symmetry and integral of motion
(Academic Press Inc Elsevier Science, 2022)
We consider a Z(2)-equivariant flow in R-4 with an integral of motion and a hyperbolic equilibrium with a transverse homoclinic orbit Gamma. We provide criteria for the existence of stable and unstable invariant manifolds ...
Maintenance optimization for a single wind turbine component under time-varying costs
(Elsevier, 2022)
In this paper, we introduce a new, single-component model for maintenance optimization under timevarying costs, specifically oriented at offshore wind turbine maintenance. We extend the standard age replacement policy ...
Multifractal spin-glass chaos projection and interrelation of multicultural music and brain signals
(Pergamon-Elsevier Science Ltd, 2023)
A complexity classification scheme is developed from the fractal spectra of spin-glass chaos and demonstrated with multigeographic multicultural music and brain electroencephalogram signals. Systematic patterns are found ...
Next-Generation Multiple Access Based on NOMA With Power Level Modulation
(IEEE-Inst Electrical Electronics Engineers Inc, 2022)
To cope with the explosive traffic growth expected in next-generation wireless networks, it is necessary to design next-generation multiple access techniques that can provide higher spectral efficiency as well as larger-scale ...
Asymmetric phase diagrams, algebraically ordered Berezinskii-Kosterlitz-Thouless phase, and peninsular Potts flow structure in long-range spin glasses
(Amer Physical Soc, 2022)
The Ising spin-glass model on the three-dimensional (d = 3) hierarchical lattice with long-range ferromagnetic or spin-glass interactions is studied by the exact renormalization-group solution of the hierarchical lattice. ...
Secure Transmission for THz-Empowered RIS-Assisted Non-Terrestrial Networks
(IEEE-Inst Electrical Electronics Engineers Inc, 2023)
The non-terrestrial networks (NTNs) are recognized as a key component to provide cost-effective and high-capacity ubiquitous connectivity in the future wireless communications. In this paper, we investigate the secure ...
Spin-s spin-glass phases in the d=3 Ising model
(Amer Physical Soc, 2021)
All higher-spin (s >= 1/2) Ising spin glasses are studied by renormalization-group theory in spatial dimension d = 3, exactly on a d = 3 hierarchical model and, simultaneously, by the Migdal-Kadanoff approximation on the ...
