A greedy perimeter stateless routing method based on a position prediction mechanism for flying ad hoc networks

open access: yesJournal of King Saud University: Computer and Information Sciences, 2023
Today, unmanned aerial vehicles (UAVs) are very popular in military and commercial applications as well as academic research. Flying ad hoc network (FANET) is a new type of ad hoc network that organizes small drones in an ad hoc form.

Speeding up Generalized PSR Parsers by Memoization Techniques [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2019
Predictive shift-reduce (PSR) parsing for hyperedge replacement (HR) grammars is very efficient, but restricted to a subclass of unambiguous HR grammars.

Approximate Message Passing in Coded Aperture Snapshot Spectral Imaging [PDF]

open access: yes, 2015
We consider a compressive hyperspectral imaging reconstruction problem, where three-dimensional spatio-spectral information about a scene is sensed by a coded aperture snapshot spectral imager (CASSI).

Basis Pursuit Receiver Function [PDF]

open access: yes, 2014
Receiver functions (RFs) are derived by deconvolution of the horizontal (radial or transverse) component of ground motion from the vertical component, which segregates the PS phases. Many methods have been proposed to employ deconvolution in frequency as

High-Resolution, Wide-Field Imaging of the Galactic Center Region at 330 MHz [PDF]

open access: yes, 2004
We present a wide field, sub-arcminute resolution VLA image of the Galactic Center region at 330 MHz. With a resolution of ~ 7" X 12" and an RMS noise of 1.6 mJy/beam, this image represents a significant increase in resolution and sensitivity over the ...

A Max-Product EM Algorithm for Reconstructing Markov-tree Sparse Signals from Compressive Samples [PDF]

open access: yes, 2013
We propose a Bayesian expectation-maximization (EM) algorithm for reconstructing Markov-tree sparse signals via belief propagation. The measurements follow an underdetermined linear model where the regression-coefficient vector is the sum of an unknown ...
