This paper presents a novel Ensemble Kalman Filter (EnKF) data assimilation method based on parameterised non-intrusive reduced order model (P-NIROM) which is independent of the original computational code. EnKF techniques involve expensive calculations ensembles. In this work, recently developed P-NIROM Xiao et al. [40] incorporated into to speed up ensemble simulations. A flow dynamical generated from solution snapshots, are obtained number high fidelity full simulations over specific...
ABSTRACT The accumulation of nonbiodegradable petrochemical‐based polymers in the environment motivates development and use low‐cost, eco‐friendly, biodegradable polymers. A series poly(butylene adipate‐co‐terephthalate) composites reinforced by sustainably sourced nanochitin were successfully prepared using melt blending compression molding methods. Structural, thermal, mechanical characterizations (PBAT)/nanochitin performed. SEM revealed that was uniformly dispersed throughout PBAT matrix...
The Zhurong rover from the China’s Tianwen-1 mission have collected meteorological data in Utopia Planitia during Mars Year 36 (MY36). This study first utilized column dust optical depth (CDOD) of MY36 observed by orbiter to analyze spatial and temporal variation near landing site Planitia.  Moreover, Global Open Planetary atmospheric model for (GoMars) was used simulate dynamics Planitia, further analyzing local circulation rover. Finally, thermal dynamical...
The Ara h 2 proteins are major determinants of peanut allergens. These have not been fully studied at the molecular level. It has previously proposed that there two isoforms 2, based on primary structures were deduced from reported cDNA sequences. In this report, four purified and characterized individually. Mass spectrometric methods used to determine protein sequences define post-translational modifications for all isoforms. Two pairs identified, corresponding a long-chain form is shorter...
A recent study reported that an aerosolized virus (COVID-19) can survive in the air for a few hours. It is highly possible people get infected with disease by breathing and contact items contaminated virus. However, transmission trajectories various meteorological environments remain unclear. This paper has investigated movement of viruses from high concentration source across dense urban area. The case looks at polluted areas London: University College Hospital (UCH) King's Cross St Pancras...
This paper focuses on how to effectively exploit the two-way relay cooperation for improving system physical-layer security with help of achieved diversity gain. It has been shown that users both play roles source and jammer during communication. Utilizing this duality users, a novel distributed selection criterion is proposed optimize secrecy outage performance. Particularly, can be implemented without any information eavesdroppers. The performance analysis probability provided. A order K/2...
Trajectory prediction is a critical part of many AI applications, for example, the safe operation autonomous vehicles. However, current methods are prone to making inconsistent and physically unrealistic predictions. We leverage insights from fluid dynamics overcome this limitation by considering internal symmetry in real-world trajectories. propose novel model, Equivariant Continous COnvolution (ECCO) improved trajectory prediction. ECCO uses rotationally-equivariant continuous convolutions...
Abstract An encryption method based on computational ghost imaging (CGI) with chaotic mapping and DNA encoding is proposed. To reduce the amount of keys in CGI-based system, algorithm used to generate random sequence as speckle measurement matrix CGI system. The data bucket detector subjected block operations, which introduce nonlinear characteristics process. problem linear vulnerability system has been greatly improved. Numerical simulation results show that, compared traditional method,...
Abstract In this study, an alternative local Galerkin method (LGM), the o3o3 scheme, is proposed. a variant or generalization of third-order spectral element (SEM3). It uses piecewise polynomials for representation field and third-degree fluxes. For discretization, SEM3 irregular Legendre–Gauss–Lobatto grid while regular collocation grid. can be regarded as inhomogeneous finite-difference scheme on uniform grid, which means that equations are different each group with three points. A...
Adaptive meshes are pivotal in numerical modeling and simulation, offering a means to efficiently, precisely, flexibly represent intricate physical phenomena, particularly when grappling with their intricacies varying scales. However, the transition from two dimensions (2D) three (3D) poses substantial challenge, as computational demands of dynamically adaptive mesh techniques increase exponentially. Addressing this challenge effectively, we turn cutting-edge realm artificial intelligence...
A new approach is proposed to use the covariant scalar equations of σ-coordinate (the method), in which pressure gradient force (PGF) has only one term each horizontal momentum equation, and PGF errors are much reduced computational space. In addition, validity reducing by this method physical space over steep terrain investigated. First, authors implement a set idealized experiments increasing slope compare those classic The results demonstrate that consistently much-reduced, compared...
The orthogonal curvilinear terrain-following coordinate (OS-coordinate) can create smooth vertical layers and computational grids, therefore reducing the advection errors in classic coordinate. reduction of by OS-coordinate had been validated idealized experiments using one kind terrain resolution. We have implemented two more types 2D linear to further analyze OS-coordinate. first experiment is use three kinds which are one-crest, three-crest, five-crest wavelike (multi-mountain...

Abstract This study illustrated the importance of smoothed vertical layers and orthogonal grids in an terrain‐following coordinate (an OTF ‐coordinate) reducing advection errors over steep terrain. Three coordinates, namely, classic coordinate, hybrid ( HTF ‐coordinate, were employed Schär‐type experiments for various terrains. The results demonstrated that ‐coordinate could diminish with high skewness terrain; share same layers. Therefore, are considerably reduced than those corresponding
