Integrating LEO Satellites and Multi-UAV Reinforcement Learning for Hybrid FSO/RF Non-Terrestrial Networks
Integrating low-altitude earth orbit (LEO) satellites (SATs) and unmanned aerial vehicles (UAVs) within a non-terrestrial network (NTN), we investigate the problem of […]
SCEMA
Protecting large-scale networks, especially Software-Defined Networks (SDNs), against distributed attacks in a cost-effective manner plays a prominent role in cybersecurity. One of […]
Origin of Enhanced Photocatalytic Activity in Direct Band Gap g-C₃N₄ Nanoribbons with Tunable Electronic Properties for Water-Splitting Reaction
In this work we employ density functional theory (DFT) to investigate the edge atomic structures and atomic boundaries in graphitic carbon nitride […]
Lifelong Fine-grained Image Retrieval
Fine-grained image retrieval has been extensively explored in a zero-shot manner. A deep model is trained on the seen part and then […]
Enforcing Statistical Orthogonality in Massive MIMO Systems via Covariance Shaping
This paper tackles the problem of downlink data transmission in massive multiple-input multiple-output (MIMO) systems where user equipments (UEs) exhibit high spatial […]
Spectral Efficiency Analysis of Hybrid Relay-Reflecting Intelligent Surface-Assisted Cell-Free Massive MIMO Systems
A cell-free (CF) massive multiple-input-multiple-output (mMIMO) system can provide uniform spectral efficiency (SE) with simple signal processing. On the other hand, a […]
Typical viewpoints of objects are better detected than atypical ones
Previous work has claimed that canonical viewpoints of objects are more readily perceived than noncanonical viewpoints. However, all of these studies required […]
Deep Learning for Instance Retrieval
In recent years a vast amount of visual content has been generated and shared from many fields, such as social media platforms, […]
Contrast-Phys
Video-based remote physiological measurement utilizes face videos to measure the blood volume change signal which is also called remote photoplethysmography (rPPG). Supervised […]
Free-Viewpoint RGB-D Human Performance Capture and Rendering
Capturing and faithfully rendering photorealistic humans from novel views is a fundamental problem for AR/VR applications. While prior work has shown impressive […]
