Multifidelity Comparison of Supersonic Wave Drag Prediction Methods Using Axisymmetric Bodies
AerospaceLow-fidelity analytic and computational wave drag prediction methods assume linear aerodynamics and small perturbations to the flow. Hence, these methods are typically accurate for only very slender geometries.

Black Holes and Complexity via Constructible Universe
Universe, 2020 The relation of randomness and classical algorithmic computational complexity is a vast and deep subject by itself. However, already, 1-randomness sequences call for quantum mechanics in their realization.

Asymptotic unbounded root loci - Formulae and computation [PDF]
1981 20th IEEE Conference on Decision and Control including the Symposium on Adaptive Processes, 1981 We study the asymptotic behavior of the dosed loop eigenvalues (root loci) of a strictly proper linear time-invariant control system as loop gain goes to \infty . The formulas are stated in terms of the eigenvalues of nested restricted linear maps of the form A(\mod S_{2})|_{S_{1}} where S 1 and S 2 are subspaces of complementary dimension.

Advanced Engineering Materials, EarlyView.We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Fast Adaptive Sparse Iterative Reweighted Super-Resolution Method for Forward-Looking Radar Imaging
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingRecently, a sparse super-resolution method based on $L_{1}$ iterative reweighted norm (IRN) has been proposed to improve the azimuth resolution of forward-looking radar.

Computing the Density of States of Boolean Formulas [PDF]
, 2010 In this paper we consider the problem of computing the density of states of a Boolean formula in CNF, a generalization of both MAX-SAT and model counting. Given a Boolean formula F, its density of states counts the number of configurations that violate exactly E clauses, for all values of E.

Advanced Engineering Materials, EarlyView.A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
Advanced Engineering Materials, EarlyView.An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

IEEE AccessWhole-body exposure to beams from fifth-generation (5G) base stations is numerically studied. Since the base stations have the capability for beamforming, the assessment of exposure to all possible beams from such stations must be performed to find the ...
