This work focuses on the production of both stationary and traveling intrinsic localized modes (ILMs), also known as discrete breathers, in two closely related electrical lattices; we demonstrate experimentally that the interplay between these two ILM types can be utilized for the purpose of spatial control. We describe a novel mechanism that is responsible for the motion of driven ILMs in this...

Intrinsic localized modes (ILMs) have been generated and characterized in two-dimensional nonlinear electrical lattices which were driven by a spatially-uniform voltage signal. These ILMs were found to be either stationary or mobile, depending on the details of the lattice unit-cell, as had already been reported in one-dimensional lattices; however, the motion of these ILMs is qualitatively dif...

Several reliable multicast schemes using router assistance have been proposed recently, which not only promise performance gains, but also simplify applications. Since they require network assistance, the effectiveness of such schemes degrades if the deployment of the required network services is sparse, meaning that an effective deployment strategy is critical. In this paper we study the perfo...

Adaptive networks include a set of nodes with adaptation and learning abilities for modeling various types of self-organized and complex activities encountered in the real world. This paper presents the effect of heterogeneously distributed incremental least mean-square (LMS) algorithm with ideal links on the quality of unknown parameter estimation. In heterogeneous adaptive networks, a fractio...

The aim of this paper is to fully analyze the effects of free space optical (FSO) communication links on the estimation performance of the adaptive incremental networks. The FSO links in this paper are described with two turbulence models namely the Log-normal and Gamma-Gamma distributions. In order to investigate the impact of these models we produced the link coefficients using these distribu...

Web-based multimedia tutorials are being developed for use in several undergraduate courses in Electrical Engineering and Computer and Systems Engineering at Rensselaer. These interactive learning modules (ILMs) are created with the Director authoring environment and can be deployed using a standard Web browser with Macromedia's Shockwave plug-in as the interface. The ILMs can be used by facult...

background: coronary angiography, albeit a safe procedure, may cause serious complications especially in patients with left main stenosis (lms). this study was designed to investigate the efficacy of workload achieved by exercise tolerance test (ett) in predicting lms in candidates for coronary angiography. methods: a total of 743 patients with a positive ett who subsequently underwent cardiac ...

This review article discussed application of ionic liquids as matrices (ILMs) for mass spectrometry (MS). ILMs were applied for matrix assisted laser desorption/ionization, (ILMALDI-MS), electrospray ionization (ILMs-ESI-MS) and desorption corona beam ionization (DCBI-MS). Ionic liquids matrices provided several advantages such as low vapor pressure, have high stability for storage and under va...

We report the observation of spontaneous localization of energy in two spatial dimensions in the context of nonlinear electrical lattices. Both stationary and moving self-localized modes were generated experimentally and theoretically in a family of two-dimensional square as well as honeycomb lattices composed of 6 × 6 elements. Specifically, we find regions in driver voltage and frequency wher...
