Defiltering turbulent flow fields for Lagrangian particle tracking using machine learning techniques
Tomoya Oura, Koji Fukagata
We propose a defiltering method of turbulent flow fields for Lagrangian particle tracking using machine learning techniques. Numerical simulation of Lagrangian particle tracking is…
The Comparison of Riemannian Geometric Matrix-CFAR Signal Detectors
Yusuke Ono, Linyu Peng
Essential characteristics of signal data can be captured by the autocovariance matrix, which, in the stationary scenarios, is Toeplitz Hermitian positive definite (HPD). In this pa…
LDA-MIG Detectors for Maritime Targets in Nonhomogeneous Sea Clutter
Xiaoqiang Hua, Linyu Peng, Weijian Liu +4
This paper deals with the problem of detecting maritime targets embedded in nonhomogeneous sea clutter, where limited number of secondary data is available due to the heterogeneity…
Cooperative dynamic polaronic picture of diamond color centers
Takuto Ichikawa, Junjie Guo, Paul Fons +3
Polarons can control carrier mobility and can also be used in the design of quantum devices. Although much effort has been directed into investigating the nature of polarons, obser…
PACiM: A Sparsity-Centric Hybrid Compute-in-Memory Architecture via Probabilistic Approximation
Wenlun Zhang, Shimpei Ando, Yung-Chin Chen +3
Approximate computing emerges as a promising approach to enhance the efficiency of compute-in-memory (CiM) systems in deep neural network processing. However, traditional approxima…
Bright-rimmed clouds in IC 1396 I. Dynamics
Yoko Okada, Slawa Kabanovic, Rolf Güsten +14
We investigate the dynamical and physical structures of bright-rimmed clouds (BRCs) in a nearby HII region. We focused on carbon- and oxygen-bearing species that trace photon-domin…
