The aim of districting problems is to get an optimized partition of a territory into smaller units, called districts or zones, subject to some side constraints such as balance, contiguity, and compactness. Logistics districting problems usuually involve additional optimization criteria and constraints. Districting problems are called continuous when the underlying space, both for facility sites...

language is the mind device to develop human’sperception from world and metaphor is the mind tool to extend the language, so poets and artists utilize metaphorsto extend language and consequently mind’sperception of reality. as we know in movement from modern to postmodern era everything including art and culture encountered a variety of changes and one of these changes was emergence of metapho...

Abstract To correctly manage the road infrastructure before and after an earthquake, it is necessary to estimate even predict seismic performance of bridge. The quantification bridge's response was present in terms displacement also based on previous research reinforced concrete bridge pier models. did define from a force lateral-displacement diagram corresponding capacity curve, calculated thr...

The bitmap obtained by scanning a printed pattern depends on the exact location of the scanning grid relative to the pattern. We consider ideal sampling with a regular lattice of delta functions. The displacement of the lattice relative to the pattern is random and obeys a uniform probability density function defined over a unit cell of the lattice. Random-phase sampling affects the edge-pixels...

A theory for the microscopic structure and the vibrational properties of soft sphere glass at finite temperature is presented. With an effective potential, derived here, the phase diagram and vibrational properties are worked out around the Maxwell critical point at zero temperature T and pressure p. Variational arguments and effective medium theory identically predict a non-trivial temperature...

The generalized parametric structural schematic diagram, the generalized structural-parametric model, and the generalized matrix transfer function of an electromagnetoelastic actuator with output parameters displacements are determined by solving the wave equation with the Laplace transform, using the equation of the electromagnetolasticity in the general form, the boundary conditions on the lo...

Localization of plastic strain induced by softening can be objectively described by a regularized plasticity model that postulates a dependence of the current yield stress on a nonlocal softening variable defined by a differential (gradient) expression. This paper presents analytical solutions of the one-dimensional localization problem under certain special nonuniform stress distributions. The...

This paper succeeded in utilizing cellular automata (CA) model to simulate the process of the train operation under the four-aspect color light system and getting the nonperiodic diagram of the mixed passenger and freight tracks. Generally speaking, the concerned models could simulate well the situation of wagon in preventing trains from colliding when parking and restarting and of the real-tim...

The top panel of Figure 1 shows a schematic diagram of the normal peripheral auditory system. The ear canal and ossicles (small bones) of the middle ear transmit acoustic signals to the cochlea where they produce a travelling wave moving from base to apex along the basilar membrane. Displacement of a segment of the basilar membrane increases the likelihood that the nerve fibers innervating hair...

Topological insulators are fascinating states of matter exhibiting protected edge states and robust quantized features in their bulk. Here we propose and validate experimentally a method to detect topological properties in the bulk of one-dimensional chiral systems. We first introduce the mean chiral displacement, an observable that rapidly approaches a value proportional to the Zak phase durin...
