Inverse source problem and minimum-energy sources.
We present a new linear inversion formalism for the scalar inverse source problem in three-dimensional and one-dimensional (1D) spaces, from which a number of previously unknown results on minimum-energy (ME) sources and their fields readily follow. ME sources, of specified support, are shown to obey a homogeneous Helmholtz equation in the interior of that support. As a consequence of that resu...
متن کاملMemetic Algorithm for Minimum Energy Broadcast Problem
A heuristic memetic algorithm for the minimum energy broadcasting problem in wireless ad hoc networks is discussed in this chapter. Broadcasting in wireless networks is different from broadcasting in wired networks because every node in wireless networks is equipped with omnidirectional antennas and several nodes are covered in a single transmission. Each node within the transmission range of t...
متن کاملOn the minimum latency problem
We are given a set of points p 1 ;. .. ; p n and a symmetric distance matrix (d ij) giving the distance between p i and p j. We wish to construct a tour that minimizes P n i=1`(i), wherè(i) is the latency of p i , deened to be the distance traveled before rst visiting p i. This problem is also known in the literature as the delivery-man problem or the traveling repairman problem. It arises in a...
متن کاملOn the minimum vocabulary problem
The “minimum vocabulary problem” for a dictionary has applications in indexing and other domains of information retrieval. A simple directed-graph model of a dictionary results in a linear-time algorithm for this problem. Since it is known that many minimum vocabularies can exist for a dictionary, a computationally useful criterion for finding a “desirable minimum vocabulary” is suggested and a...
متن کاملReservoir Computing on the Hypersphere
Reservoir Computing (RC) refers to a Recurrent Neural Networks (RNNs) framework, frequently used for sequence learning and time series prediction. The RC system consists of a random fixedweight RNN (the input-hidden reservoir layer) and a classifier (the hidden-output readout layer). Here we focus on the sequence learning problem, and we explore a different approach to RC. More specifically, we...
