the process of stage designing in its traditional and usual sense, takes its basic roots from the conscious mind of the designer rather than his/her unconscious mind. in the meantime, the unconscious mind has a unique power and the modern visual arts- especially after the second world war- have tended towards by using different methods such as happenings and abstract designing. however, the tra...

Prothrombin, both by a one- and a two-stage method, and progressive antithrombin were determined on the same plasma samples from 47 patients with cirrhosis and 27 patients with acute hepatitis. In the first group prothrombin estimated by the two-stage method was significantly higher than by the one-stage method. The values were often within the normal range and were not correlated with the indi...

In the current study we investigate the two-stage iterative method for solving linear systems. Our new results shows which splitting generates convergence fast in iterative methods. Finally, we solve the Poisson-Block tridiagonal matrix from Poisson's equation which arises in mechanical engineering and theoretical physics. Numerical computations are presented based on a particular linear system...

brucella melitensis and brucella abortus are of the most important causes of brucellosis, an infectious disease which is transmitted either directly or indirectly including consuming unpasteurized dairy products. both strains are considered endemic in iran. common diagnostic methods such as bacteriologic cultures are difficult and time consuming regarding the bacteria. the aim of this study was...

the hub location decision is a long term investment and any changes in it take considerable time and money. in real situations, some parameters are uncertain hence, deterministic models cannot be more efficient. the ability of two-stage stochastic programming is to make a long-term decision by considering effects of it in short term decisions simultaneously. in the two-stage stochastic programm...

For reliability-based topology optimization (RBTO) of double layer grids, a two-stage optimization method is presented by applying “Solid Isotropic Material with Penalization” and “Ant Colony Optimization” (SIMP-ACO method). To achieve this aim, first, the structural stiffness is maximized using SIMP. Then, the characteristics of the obtained topology are used to enhance ACO through six modific...

Software testing is a task of quality assurance where the main aim is to identify errors. Graphical User Interfaces (GUIs), a class of Event-Driven Software (EDS), is increasingly used to increase the human-to-computer interaction. General tests are not applied directly to GUIs because of the increased number of states generated because of huge number of permutations of input events. This paper...
