Symbol detection in online handwritten graphics using Faster R-CNN
, 2017 Symbol detection techniques in online handwritten graphics (e.g. diagrams and mathematical expressions) consist of methods specifically designed for a single graphic type. In this work, we evaluate the Faster R-CNN object detection algorithm as a general

Greenhouse Gases: Science and Technology, Volume 14, Issue 1, Page 4-10, February 2024.Abstract We have developed a portable active seismic source (PASS) to monitor CO2 storage reservoirs at a depth of approximately 1 km. Despite its small size, stacking the signals generated by the PASS improves the signal‐to‐noise ratio of the seismometer data far from the source.

Sensing Optical Fibers for Earthquake Source Characterization Using Raw DAS Records
Journal of Geophysical Research: Solid Earth, Volume 129, Issue 1, January 2024.Abstract Distributed Acoustic Sensing (DAS) is becoming a powerful tool for earthquake monitoring, providing continuous strain‐rate records of seismic events along fiber optic cables. However, the use of standard seismological techniques for earthquake source characterization requires the conversion of data in ground motion quantities. In this study we

Effect of Random Parameter Switching on Commensurate Fractional Order Chaotic Systems
, 2016 The paper explores the effect of random parameter switching in a fractional order (FO) unified chaotic system which captures the dynamics of three popular sub-classes of chaotic systems i.e. Lorenz, Lu and Chen's family of attractors.
