In this paper, with respect to the advantages of geometric phase in quantum computation, we calculate the geometric phase of the optomechanical systems. This research can be considered as an important step toward using the optomechanical systems in quantum computation with utilizing its geometric phase.
The Stein-Chen method for Poisson approximation is adapted to the setting of the geometric distribution. This yields a convenient method for assessing the accuracy of the geometric approximation to the distribution of the number of failures preceding the first success in dependent trials. The results are applied to approximating waiting time distributions for patterns in coin tossing, and to ap...
heuristics are often used to provide solutions for flow shop scheduling problems.the performance of a heuristic is usually judged by comparing solutions and run times on test cases.this investigation proposes an analytical alternative ,called asymptotic convergence ,which tests the convergence of the heuristic to a lower bound as problem size grows. the test is a stronger variation of worst cas...
Consider two real-life problems. First, suppose you have a collection of nails hammered into a board. If you were to stretch a rubber band around the outside of the nails and let it snap, what shape would the rubber band take? Second, imagine two planes whose trajectories and flight patterns show that they must, at one instance in time, fly dangerously close to one another—will they collide? In...
the brush-tailed mice of the genus calomyscus are distributed in the mountains of central asia and the middle east. the genus calomyscus represents five nominate species from iran (c. bailwardi, c. grandis, c. hotsoni, c. urartensis and c. elburzensis). in total 64 specimens from four species of calomyscus were studied for morphometric analyses the morphological differences among 10 populations...
This chapter focuses on three computer-aided geometric design (CAGD) techniques that are often needed to \prepare" a complex geometry for grid generation. Standard grid generation methods, as discussed in [George '91], [Knupp & Steinberg '93], and [Thompson et al. '85], assume that parametric surfaces are well parametrized and free of undesired discontinuities. We describe CAGD techniques that ...
By using a second quantized formulation of level crossing, which does not assume adiabatic approximation, a convenient formula for geometric terms including offdiagonal terms is derived. The analysis of geometric phases is reduced to a simple diagonalization of the Hamiltonian in the present formulation. If one diagonalizes the geometric terms in the infinitesimal neighborhood of level crossing...
Qavam al-Din Shirazi is one of the prominent architects of the Timurid era who has memorized many works such as the Goharshad Mosque in Mashhad and the Herat Goharshad Mosque. What is considered as an architectural work in the study of a building is the material and physical aspects of the architectural space. Due to the destruction of Heratchr('39')s Goharshad Mosque, one of the ways to unders...
The output maneuvering problem involves two tasks. The first, which is the geometric task, is to force the output to converge to a desired path parametrized by a continuous scalar variable θ. The second task is to satisfy a desired speed assignment along the path. The main concern is to satisfy the geometric task. However, the speed assignment will ensure that the output follows the path with s...
The maneuvering problem involves two tasks. The first, called the geometric task, is to force the system output to converge to a desired path continuously parametrized by a scalar θ. The second task, called the dynamic task, is to satisfy a desired dynamic behavior along the path. In this paper, this dynamic behavior is further specified as a speed assignment for θ(t). While the main concern is...
