Intelligent inspection robots are widely used in substation patrol
inspection, which can help check potential safety hazards by patrolling the
substation and sending back scene images. However, when patrolling some
marginal areas with weak ...
High-resolution Power Doppler Using Null Subtraction Imaging
January 9, 2023
| | | | |
Electrical Engineering and Systems Science
Signal Processing
To improve the spatial resolution of power Doppler (PD) imaging, we explored
null subtraction imaging (NSI) as an alternative beamforming technique to
delay-and-sum (DAS). NSI is a nonlinear beamforming approach that uses three
different ap...

Analysis of PDEs
Functional Analysis
We show a result on propagation of the anisotropic Gabor wave front set for
linear operators with a tempered distribution Schwartz kernel. The anisotropic
Gabor wave front set is parametrized by a positive parameter relating the space
and f...
Reduced clique graphs: a correction to "Chordal graphs and their clique graphs"

Mathematics
Combinatorics
Galinier, Habib, and Paul introduced the reduced clique graph of a chordal
graph . The nodes of the reduced clique graph are the maximal cliques of
, and two nodes are joined by an edge if and only if they form a
non-disjoint separati...
Cross-Model Comparative Loss for Enhancing Neuronal Utility in Language Understanding

Current natural language understanding (NLU) models have been continuously
scaling up, both in terms of model size and input context, introducing more
hidden and input neurons. While this generally improves performance on average,
the extra...
EDGES of the dark forest: A new absorption window into the composite dark matter and large scale structure

We propose a new method to hunt for dark matter using dark forest/absorption
features across the whole electromagnetic spectrum from radio to gamma rays,
especially in the bands where there is a desert i.e. regions where no strong
lines fro...

This work focuses on the use of reconfigurable intelligent surface (RIS) in
dual-function radar-communication (DFRC) systems to improve communication
capacity and sensing precision, and enhance coverage for both functions. In
contrast to mo...
