The theory of plane, elastic trusses is reconsidered from the viewpoint of the continuum theory of elastic media. A main difference between continuum and discrete theories is the following: In the continuous case all quantities are declared throughout the whole body, whereas in the discrete case each quantity has its own “carrier”. In a truss, for instance, displacements and applied forces are ...

Understanding and controlling spreading dynamics in networks presupposes the identification of those influential nodes that will trigger an efficient information diffusion. It has been shown that the best spreaders are the ones located in the core of the network – as produced by the k-core decomposition. In this paper we further refine the set of the most influential nodes, showing that the nod...

We consider semidefinite programming (SDP) formulations of certain truss topology optimization problems, where a lower bound is imposed on the fundamental frequency of vibration of the truss structure. These SDP formulations were introduced in: [M. Ohsaki, K. Fujisawa, N. Katoh and Y. Kanno, Semi-definite programming for topology optimization of trusses under multiple eigenvalue constraints, Co...

In this paper, based on maximizing the outrigger-belt truss system’s strain energy, a methodology for determining the optimum location of an outrigger-belt truss system is presented. Tall building structures with combined systems of framed tube, shear core and outrigger-belt truss system’s are modeled using continuum approach. In this approach, the framed tube system is modeled as a cantilevere...

a 15-landmark morphometric truss network system was used to investigate the hypothesis of population fragmentation of shad fish alosa braschnicowi borodin, 1904 along the southern caspian sea. a total of 181 a. braschnicowi specimens were caught from six localities, respectively from the west to the east including; astara, rezvanshahr, anzali, tonekabon, sari and miankale. principal component a...

In recent years, the optimization of truss structures has been considered due to their several applications and their simple structure and rapid analysis. DNA computing algorithm is a non-gradient-based method derived from numerical modeling of DNA-based computing performance by new computers with DNA memory known as molecular computers. DNA computing algorithm works based on collective intelli...

in this paper, matlab code for a recently developed meta-heuristic methodology, the vibrating particles system (vps) algorithm, is presented. the vps is a population-based algorithm which simulates a free vibration of single degree of freedom systems with viscous damping. the particles gradually approach to their equilibrium positions that are achieved from current population and historically b...

Rangka batang (truss) adalah sistem struktural yang terdiri dari sejumlah bagian (batang), masing-masing diyakini bertindak sebagai sambungan pada simpulnya dan hanya dapat menahan gaya aksial. Pengukuran gaya-gaya rangka sederhana (truss apparatus) merupakan salah satu modul dalam Praktikum Fenomena Dasar Mesin. ini bertujuan agar mahasiswa mampu memahami perhitungan parameter-parameter pentin...
