A real-time statistical time-series analyzer [PDF]

, 1971
Device extracts average frequency of human speech and produces second, third, and fourth moments of instantaneous frequency about this average. It operates on electrical time representation of input signal, performs statistical analysis on zero-crossing ...

Real-Time Hand Shape Classification

, 2014
The problem of hand shape classification is challenging since a hand is characterized by a large number of degrees of freedom. Numerous shape descriptors have been proposed and applied over the years to estimate and classify hand poses in reasonable time.

Optimal Data Acquisition and Height Retrieval in Repeat-Track Geosynchronous SAR Interferometry

Remote Sensing, 2015
Geosynchronous synthetic aperture radar (GEO SAR) will move in a high orbit of ~36,000 km with a long integration time of hundreds of seconds. It is obviously impacted by orbital perturbations and the Earth’s rotation, which can give rise to un-parallel ...

Adaptive Real Time Imaging Synthesis Telescopes [PDF]

, 2012
The digital revolution is transforming astronomy from a data-starved to a data-submerged science. Instruments such as the Atacama Large Millimeter Array (ALMA), the Large Synoptic Survey Telescope (LSST), and the Square Kilometer Array (SKA) will measure

Modelling of continuously distributed target for bistatic synthetic aperture radar imaging

The Journal of Engineering, 2020
The point target model is widely used in the synthetic aperture radar (SAR) imaging simulation. Based on this model, the radar echo of a continuously distributed target can be expressed as the linear summation of the echo of many point targets which are ...

Real-time, pseudo real-time, and linear-time ITA

Theoretical Computer Science, 1986
A k-ary iterative tree automaton (k-ary ITA) is a potentially infinite synchronous network of finite automata structured as k-ary tree with serial input and output at the root of the tree. The computational power of an ITA in real-time, pseudo real-time and linear-time is compared.
