We study dark solitons, namely density dips with a phase jump across the density minimum, in a here one-dimensional, weakly lossy nonlinear acoustic metamaterial, composed of a waveguide featuring a periodic array of side holes.Relying on the electroacoustic analogy and the transmission line approach, we derive a lattice model which, in the continu
Self-compacted concrete (SCC) is a highly flowable concrete, with no segregation which can be quest fryer spread into place by filling the structures framework and permeate the reinforcement without any compaction or mechanical consolidation ACI 237R-14.One of the most important problems faced by concrete industry in Iraq and Gulf Arab land is dete
Abstract Background Several criteria exist to identify the optimal model for quantification of tracer here kinetics.The purpose of this study was to evaluate the correspondence in kinetic model preference identification for brain PET studies among five model selection criteria: Akaike Information Criterion (AIC), AIC unbiased (AICC), model selectio
E-books embody diverse features, each of which could contribute towards increasing their user-agreeability and attracting more users.In order to select an ice blue graphic tee Ebook best suited to their needs, both users and librarians consider a set of criteria.The present study aims at providing the evaluation criteria from the standpoint of both
