In this paper, a method for estimating cell capacity from network measurements in a multiservice long-term evolution (LTE) system is presented. Unlike previous work, the proposed method takes into account multiple service-specific constraints, including both delay and throughput constraints. For this purpose, services are first classified by their quality-of-service (QoS) class identifier (QCI). Then,...
In their most general form, wave-interface problems are inherently angular in nature. For instance, the interaction between light waves and material boundaries essentially defines the entire field of optics. The seminal works of Aceves et al. [1,2] considered scalar bright spatial solitons impinging on the planar interface between two Kerr-type media with different χ(3) susceptibilities. While these...
An event-based method to perform the set-point following task for second order processes with time delay (SOPTD) is investigated in this work. The aim of the research is to extend an event-based controller that has been tested previously in processes responding to the first-order with time delay (FOPTD) model. The controller is based on feedforward and feedback actions to do the two main tasks of...
Among nonlinear-phenomena in propagation trough a nonlinear stack, switching describes change from an evanescent mode to a cavity stack mode. We use the analysis of Winful to extend previous results of a 1D nonlinear Stack.
We give a brief overview of some new results in Helmholtz soliton theory. Firstly, fundamental considerations are made in terms of new contexts for Helmholtz solitons that arise directly from Maxwells equations. We then detail applications of Helmholtz solitons in material interface geometries: generalising Snells law to nonlinear beams and reporting new qualitative phenomena. Novel families of bistable...
