objective : the present study is investigating the attribution style in patients with the anxiety and depression comorbidity. method: subjects are 26 patients with major depression, 25 patients with generalized anxiety disorder, 17 patients with comorbidity of anxiety and depression, and 30 normal individuals. the aparatus used in the study for data collecting were beck depression inventory, be...

background: anxiety disorders and substance abuse are commonest comorbidities among bipolar i disorder (bid) patients. this study investigated the prevalence of anxiety disorders among bid patients based on their dependency on opioid. methods: in this cross sectional study the bid patients in iranian hospital of psychiatry were divided into two 89-patient groups; one group was considered as opi...

first riccati equation with matrix variable coefficients, arising in optimal and robust control approach, is considered. an analytical approximation of the solution of nonlinear differential riccati equation is investigated using the adomian decomposition method. an application in optimal control is presented. the solution in different order of approximations and different methods of approximat...

In this paper we investigate Donder-Weyl (DW) Hamilton-Jacobi equations and establish the connection between DW Hamilton-Jacobi equations and multi-symplectic Hamiltonian systems. Based on the study of DW Hamilton-Jacobi equations, we present the generating functions for multi-symplectic partitioned Runge-Kutta (PRK) methods.

A Hamilton cycle is a cycle containing every vertex of a graph. A graph is called Hamiltonian if it contains a Hamilton cycle. The Hamilton cycle problem is to find the sufficient and necessary condition that a graph is Hamiltonian. In this paper, we give out some new kind of definitions of the subgraphs and determine the Hamiltoncity of edges according to the existence of the subgraphs in a gr...

We propose a Hamilton-Jacobi equation approach for computing time-optimal trajectories of a vehicle which travels under certain curvature constraints. We derive a class of Hamilton-Jacobi equations which models such motions; it unifies two well-known vehicular models, the Dubins’ and Reeds-Shepp’s cars, and gives further generalizations. We show that the value function of the control problem so...
