Undular bores, also termed dispersive shock waves, generated by an initial discontinuity in height as governed two forms of the Boussinesq system weakly nonlinear shallow water wave theory, standard formulation and a Hamiltonian formulation, related Whitham–Boussinesq equations, full equations for gravity surface waves are studied compared. It is found that systems give solutions excellent agre...

We solve the St. Venant torsion problem for an infinite cylindrical rod whose behaviour is described by a family of isotropic generalized continua, including relaxed micromorphic and classical model. The results can be used to determine material parameters these models. Special attention given possible nonphysical stiffness singularity vanishing diameter, because slender specimens are, in gener...

purpose: this study aimed to investigate the status of the open access policies of highly-ranked digital repositories in the world’s universities by identifying the policies regarding the components of submission, content, data, meta-data, preservation, and access. methodology: this survey was descriptive-analytical. data was collected by administrating a researcher-made questionnaire completed...

by virtue of a complete set of two displacement potentials, an analytical derivation of the elastostatic green’s functions of an exponentially graded transversely isotropic bi-material full-space was presented. three-dimensional point-load green’s functions for stresses and displacements were given in line-integral representations. the formulation included a complete set of transformed stress-p...

This paper describes an application model that couples Analytical Hierarchy Process(AHP) and fuzzy comprehensive evaluation method , which named Fuzzy-AHP(FAHP). AHP has its own superiority in computing index weight and comparing index in the same row than at classifying level. While fuzzy comprehensive evaluation method is good at classifying level. Taking into account their respective advanta...

Consider a simple two-way relaying channel where two single-antenna sources exchange information via a multiple-antenna relay. To such a scenario, all the existing works which can achieve full diversity order are based on the antenna/relay selection, where the difficulty to design the beamforming lies in the fact that a single beamformer needs to serve two destinations. In this paper, we propos...

A new adaptive technique is presented for building multidimensional parameterized analytical models for general planar microwave structures with a predefined accuracy and based on full-wave electromagnetic (EM) simulations. The models can be incorporated in a circuit simulator and the time required to calculate the circuit representation of a practical network is reduced by several orders of ma...

We study the static and dynamical properties of isolated many-body quantum systems and compare them with the results for full random matrices. In doing so, we link concepts from quantum information theory with those from quantum chaos. In particular, we relate the von Neumann entanglement entropy with the Shannon information entropy and discuss their relevance for the analysis of the degree of ...
