Individuals with obstructive sleep apnea (OSA) can experience partial or complete collapse of the upper airway during sleep. This condition affects between 10-17% of adult men and 3-9% of adult women, requiring arousal to resume regular breathing. Frequent arousals disrupt proper sleeping patterns and cause daytime sleepiness. Untreated OSA has been linked to serious medical issues including cardiovascular...
A non-contact vision-based system is presented for continuous respiratory rate monitoring. The system identifies feature points in a video feed and tracks them over time. Two methods are presented for comparison — a method which uses principal component analysis (PCA) and a simple averaging approach. These methods condense the feature point trajectories into a compact set of representative signals...
Almost all plants have the experience of ACB's overcurrent relay (OCR) unexpectedly trip event. Each accident will cause a huge production loss. But manufacturers of OCR can't afford the cost-effective solution of problem. The most used solution is to install an additional relay (ex. ABB Relay B) to replace the function of the ACB's OCR or to adopt a new ACB to replace the old one. These two uneconomical...
A Real Time Power Monitoring (RTPM) System is proposed in which end-use detailed energy consumption data is provided for each load level. The data will be integrated with a BIM (Building Information Modeling) Model to create a Realtime on-line electronic BIM Model. This paper describes the RTPM system and the process leading to its creation. The basic components of the proposed system were designed...
Widely applied in many domains, data stream processing has attracted more and more attention in database and sensor network communities. In this demo, we present our system PEDS-VM, a real-time surveillance system for managing pattern variation over evolving medical streams. PEDS-VM utilizes an effective strategy and a state-based window framework to extract the evolving patterns. After extraction,...
Experiments on Z-pinch has been carried out based on a 2 MA pulsed power facility. Gas puff and wire array liners were tested at current 1.4 ∼ 2.1 MA with rise time 80 ∼ 100 ns. For Krypton specific mass of 23 and 47 µg/cm, soft X-ray yield of 55 and 62 kJ, radiation power of 1.9 and 1.7 TW have been obtained, with imploding time of 90 and 118 ns corresponding to current of 1.4 and 1.5 MA and rise...
