This paper presents a novel process of extracting lead oxide nanoparticles from cathode-ray tube (CRT) funnel glass using self-propagating high-temperature synthesis (SHS) method. The impacts of added amount of funnel glass on the extraction ratio of lead, the lead extraction velocity and the micromorphology, as well as particle size of extracted nanoparticles were investigated. We found that s...

This work is a comprehensive extension of Abu-Salem et al. (2015) that investigates the prowess of the Funnel Heap for implementing sums of products in the polytope method for factoring polynomials, when the polynomials are in sparse distributed representation. We exploit that the work and cache complexity of an Insert operation using Funnel Heap can be refined to depend on the rank of the inse...

Using a particle-based model, we simulate the behavior of skyrmion under influence asymmetric funnel geometries and ac driving at zero temperature. We specifically investigate possibilities for controlling motion by harnessing ratchet effect. Our results show that as amplitude unidirectional drive is increased, can be set into along either easy or hard direction depending on direction. When par...
