‎the main purpose of this paper is to study the numerical solution of nonlinear volterra integral equations with constant delays, based on the multistep collocation method. these methods for approximating the solution in each subinterval are obtained by fixed number of previous steps and fixed number of collocation points in current and next subintervals. also, we analyze the convergence of the...

Systems of differential-algebraic equations (DAEs) are generated routinely by simulation and modeling environments, such as MapleSim and those based on the Modelica language. Before a simulation starts and a numerical method is applied, some kind of structural analysis is performed to determine which equations to be differentiated, and how many times. Both Pantelides’s algorithm and Pryce’s Σ -...

The purpose of this study is to examine the possible impact of value systems on earnings management in France, Tunisia and Canada. Cultural values include power distance, uncertainty avoidance, individualism, masculinity and long-term orientation. The cross-cultural study uses the method of structural equations trough LISREL approach. The examination covers the period between 2003 and 2009. Fin...

In this paper we apply the method of inferred causation for macroeconomic analysis. First we introduce briefly the theory of inferred causation developed by Pearl and Verma (1991). We apply this method to the identification of structural vector autoregression (SVAR) models. In an example of monetary policy analysis we demonstrate how causal information embedded in the data can be used to identi...

We derive a closed form expression for the asymptotic distribution of the LIML estimator for the coefficients of both endogenous and exogenous variables in a partially identified linear structural equation. We extend previous results of Phillips (1989) and Choi and Phillips (1992) where the focus was on IV estimators. We show that partial failure of identification affects the LIML in that its m...

Presently there is a little information that relates to heat shield systems.  Also this information is not certain in so many cases.  The main reason is that accurate calculations for measuring the sacrificing rate of various materials have not been obtained yet.  Additionally, the real scale test has two disadvantages: high cost and low flexibility, and for each case we must perform a new test...
