Mismatched Estimation in the Distance Geometry Problem

2022 56TH ASILOMAR CONFERENCE ON SIGNALS, SYSTEMS, AND COMPUTERS, pp. 1031–1035.

By: M. Abdelkhalek n, D. Baron n & C. Wong n

TL;DR: This paper argues that more accurate estimates can be obtained when an estimation procedure that uses the correct likelihood function of noisy measurements is performed, and demonstrates that least-squares estimates could be suboptimal by several dB. (via Semantic Scholar)

Investigating the Relationship between Cough Detection and Sampling Frequency for Wearable Devices

2021 43RD ANNUAL INTERNATIONAL CONFERENCE OF THE IEEE ENGINEERING IN MEDICINE & BIOLOGY SOCIETY (EMBC), pp. 7103–7107.

By: M. Abdelkhalek n, J. Qiu n, M. Hernandez*, A. Bozkurt n & E. Lobaton n

MeSH headings : Algorithms; Cough / diagnosis; Humans; Neural Networks, Computer; Reproducibility of Results; Wearable Electronic Devices
TL;DR: This paper presents a new cough detection technique and preliminary analysis on the trade-off between detection accuracy and obfuscation of speech for privacy, and indicates that, using a publicly available dataset, it can sample signals at 750 Hz while still maintaining a sensitivity above 90%, suggested to be sufficient for clinical monitoring.

Resonance frequency selective electromagnetic actuation for high-resolution vibrotactile displays

SENSORS AND ACTUATORS A-PHYSICAL, 302.

By: A. Mohammadi*, M. Abdelkhalek n & S. Sadrafshari*

author keywords: Vibrotactile display; Electromagnetic actuator; Spatial resolution; Frequency multiplexing; Resonance frequency
TL;DR: A new selective electromagnetic actuation technique to control the vibrations of multiple tactile elements using a single coil based on their individual mechanical resonance frequencies is presented, allowing low-cost and highly reliable implementation of many tactile elements on a smaller area.
