VR-Spy: A Side-Channel Attack on Virtual Key-Logging in VR Headsets
Presented at the 2021 IEEE Virtual Reality and 3D User Interfaces (VR).
Event: 2021 IEEE Virtual Reality and 3D User Interfaces (VR)
TL;DR:
This is the first work that uses WiFi signals to recognize virtual keystrokes in VR headsets using channel state information (CSI) of WiFi signals, and the key idea behind VR -Spy is that the side-channel information of fine-granular hand movements associated with each virtual keystroke has a unique gesture pattern in the CSI waveforms.

Mixed-criticality real-time scheduling of gang task systems
Real-Time Systems, 57(3), 268–301.
TL;DR:
This work addresses the MC scheduling of parallel tasks of gang model that allows workloads to execute on multiple cores simultaneously, as well as the change to degree of parallelism of a task upon a mode switch, and proposes a new technique GEDF-VD, which integrates Global Earliest Deadline First (GEDF) and Earliest deadline First with Virtual Deadline (EDf-VD).

COMO: Efficient Deep Neural Networks Expansion With COnvolutional MaxOut
IEEE Transactions on Multimedia, 23, 1722–1730.
TL;DR:
The classic MaxOut strategy is extended into COnvolutional MaxOut (COMO) — a new strategy making deep convolutional neural networks wider with parameter efficiency, which outperforms the existing solutions that make networks wider, and it dominates in the comparison of accuracy versus parameter sizes.
