Tracking Reentries of Starlink Satellites During the Rising Phase of Solar Cycle 25
The exponential increase of low-Earth orbit (LEO) satellites in the past 5 years has brought into intense focus the need for reliable monitoring and reentry prediction to safeguard from space collisions and ground debris impacts. However, LEO satellites fly within the upper atmosphere region that exerts significant drag forces to their orbits, reducing their lifetimes, and increasing collision risks during dynamic events, like geomagnetic storms. Such conditions can become more severe during ge…

Leveraging 5G Physical Layer Monitoring for Adaptive Remote Rendering in XR Applications
As immersive eXtended Reality (XR) applications demand substantial network resources, understanding their interaction with 5G networks becomes crucial to improve them. This paper investigates the role of 5G physical-layer monitoring to manage and enhance the remote rendering of XR content dynamically. By observing network metrics directly from the physical layer, we propose a system to adapt streaming parameters such as bitrate, framerate, and resolution in real time based on available network …

An Attack Method for Medical Insurance Claim Fraud Detection based on Generative Adversarial Network
Insurance fraud detection represents a pivotal advancement in modern insurance service, providing intelligent and digitalized monitoring to enhance management and prevent fraud. It is crucial for ensuring the security and efficiency of insurance systems. Although AI and machine learning algorithms have demonstrated strong performance in detecting fraudulent claims, the absence of standardized defense mechanisms renders current systems vulnerable to emerging adversarial threats. In this paper, w…

Très triste de voir Montréal dans une grève de la #STM
Toronto a passé Š un cheveux l’an passé d’avoir une grève. La mairesse Chow a tout fait pour l’empêcher, ça été annulé de justesse quelques heures avant le début de la grève. Elle avait compris qu’un système déjŠ affaibli par COVID ne se remettrait pas d’une autre baisse d’achalandage et qu’il fallait Š tout pris ramener la clientèl…

Towards Underwater Detection of Diluted Bitumen with Interdigital Sensors
Diluted bitumen spills in freshwater environments pose significant challenges for detection and remediation due to the complex behaviour of the material once released, rendering traditional oil monitoring techniques, such as aerial surveys and fluorometry, ineffective. This study investigates the feasibility of utilizing interdigital capacitive sensors to detect dilbit in water via frequency-dependent impedance measurements. Three sensor designs were fabricated and tested with a vector network …
