Recently, there has been significant interest in the study of the community search problem in social and information networks: given one or more query nodes, find densely connected communities containing the query nodes. However, most existing studies do not address the “free rider” issue, that is, nodes far away from query nodes and irrelevant to them are included in the detected community. So...

Using energy absorption systems in the structures with malfunctioning components is of paramount importance. By absorbing the seismic energy, these systems help the components of the structure to remain resilient during earthquake. In the present study, viscous dampers were applied in order to enhance the reactions of tall building with belt truss. To assess the response of a structure un...

We present results for the pion multiplet spectrum calculated using both unimproved staggered fermions and improved HYP-smeared staggered fermions. In the case of unimproved staggered fermions, we observe (consistent with previous work) that O(a2) taste symmetry breaking effects are large and comparable to the ≈ O(p2) contributions to their masses. Higher order O(a2 p2) effects are also substan...

Quasi-static uniform compression tests and low-velocity concentrated impact tests were conducted to reveal the failure mechanisms and energy absorption capacity of two-layer carbon fiber composite sandwich panels with pyramidal truss cores. Three different volume-fraction cores (i.e., with different relative densities) were fabricated: 1.25%, 1.81%, and 2.27%. Two-layer sandwich panels with ide...

When we represent real-world systems as networks, the directions of links often convey valuable information. Finding module structures that respect link directions is one of the most important tasks for analysing directed networks. Although many notions of a directed module have been proposed, no consensus has been reached. This lack of consensus results partly because there might exist distinc...

background and aim: electrical discharges in temporal lobe epilepsy can cause disorders in auditory pathways. staggered spondaic word test ( ssw) is one of the most common behavioral tests to evaluate the central auditory nervous system. this study aimed to evaluate and compare auditory processing problems in temporal lobe epileptic patients and normal subjects with persian ssw test. methods: t...

This paper presents a hybrid geometric modeling method to create CAD models of large-scale conformal cellular structures effectively and efficiently. Cellular material structures can be engineered at the mesoscopic scale for high performance and multifunctional capabilities. One type of cellular structure is conformal lightweight truss. A simple method of constructing models of uniform trusses ...

A staggered Runge-Kutta (staggered RK) scheme is the time integration Runge-Kutta type scheme based on staggered grid, which was proposed by Ghrist and Fornberg and Driscoll in 2000. Afterwords, Vewer presented efficiency of the scheme for linear and semilinear wave equations through numerical experiments. We study stability and convergence properties of this scheme for semilinear wave equation...

Abstract As an optimization that starts from a randomly selected structure generally does not guarantee reasonable optimality, the use of systemic approach, named ground structure, is widely accepted in steel-made truss and frame structural design. However, case reinforced concrete (RC) optimization, because orthogonal orientation members, chosen or architect-sketched framing used. Such one-tim...
