Fusion of Channel State Information and Received Signal Strength for Indoor Localization Using a Single Access Point

Remote Sensing, 2020
: In recent years, indoor localization systems based on fingerprinting have had significant advances yielding high accuracies. Those approaches often use information about channel communication, such as channel state information (CSI) and received signal ...

Effective Modeling of Continuous Wave Z$$ Z $$‐Spectra for Quantitative CEST and CESL MRI Across Exchange Regimes

Magnetic Resonance in Medicine, EarlyView.
Purpose Chemical exchange saturation transfer (CEST) and chemical exchange‐sensitive spin‐lock (CESL) MRI enable spectroscopic imaging with high sensitivity, but conventional analysis methods often fail as exchange approaches the fast‐exchange limit.

Effects of Esketamine on Emergence Delirium in Children Undergoing Sevoflurane Anesthesia: A Systematic Review, Meta‐Analysis, and Trial Sequential Analysis

Pediatric Anesthesia, EarlyView.
ABSTRACT Background Emergence delirium is a frequent and distressing postoperative complication in children, particularly following sevoflurane‐based anesthesia. Despite its clinical importance, the optimal preventive strategy remains under investigation.

A Multifrequency Seamless Dual-Link Handover Scheme Based on Beamforming for High-Speed Railway

International Journal of Antennas and Propagation, 2023
This paper proposes a multifrequency seamless dual-link handover scheme based on beamforming for the high-speed railway (HSR) communication, i.e., when the train travels to the edge of overlapping area of the adjacent two cells, a gain beam is assigned ...

Advanced Hybrid Techniques for Cyberattack Detection and Defense in IoT Networks

SECURITY AND PRIVACY, Volume 8, Issue 2, March/April 2025.
ABSTRACT The Internet of Things (IoT) represents a vast network of devices connected to the Internet, making it easier for users to connect to modern technology. However, the complexity of these networks and the large volume of data pose significant challenges in protecting them from persistent cyberattacks, such as distributed denial‐of‐service (DDoS)

BDALT: Bilateration and Double Anchor-based Localization Technique for Wireless Sensor Networks using Angle of Arrival (AoA) and Received Signal Strength (RSS) -A Hybrid Technique

International Journal of Engineering and Advanced Technology, 2019
Anchor based localization techniques are better and cost free alternate solutions against GPS based localization techniques in Wireless Sensor Networks (WSN) applications. Anchor based localization techniques using Zigbee technology in WSN have attracted highly in the recent years.

Boosting Embodied Visual Localisation Through Multi‐Granular Semantics and Multi‐Robot Consensus

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Achieving high accuracy and synergy remains extremely difficult for multi‐robot embodied visual localisation, which suffers from persistent real‐world challenges such as viewpoint ambiguity, appearance variation and dynamic occlusion. Conventional optimisation‐based methods often lead to incorrect feature matching without domain adaptation ...

The Power Gain Difference Method Analysis

Sensors, 2020
In this paper, we propose a new approach to passively locate the 3D position of a signal source. This novel technique, called the power gain difference (PGD), is based only on measuring the received signal strength (RSS) with multiple sensors deployed in
