over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
the effect of the presence of perforations on he stresses of a plate is a problem which is of great interest in structural design and in the mathemattical theory of elasticity. among the many hole patterns that are likely to require consideration is the ring of equally spaced circular holes. the present worke investigates stress & strain analysis of a thin isotropic circular plate containing a ...
برای استفاده از روش تفاضلهای محدود (finite difference method) در حل عددی معادلات حاکم بر جریانهای لزج با مرزهای پیچیده، معمولا این معادلات در یک دستگاه مختصات محاسباتی که منطبق بر مرزهاست نوشته میشوند. برای این منظور میبایست ابتدا شبکه ای که رابطه بین حوزه های فیزیکی و محاسباتی جریان را مشخص میکند، محاسبه شود. هدف از انجام این تحقیق تولید یک شبکه متعامد منطبق بر مرزها در حوزه جریان دو بعدی ...
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
Age-related changes in al-, a?-, and 0-catecholamine receptors on membranes of rat epididymal fat cells were investigated. Both young (6 weeks old, weight about 190 g) and aged (20 weeks old, weight about 490 g) Sprague-Dawley male rats were used. For the a]-adrenoceptor binding experiment, we developed a novel analytical method using the hydrophilic a]receptor selective antagonist, [3H]bunazos...

in this research we have studied the effect of some transition-metals (cu, ag and au) substitutions on two-electron reduction potential of flavins by application of dft method. all geometries have been optimized at blyp level of theory and “6-31+g** + lanl2dz” mixed basis set. the frequency job at the same method and basis sets has been performed to obtain gibbs free energy of compounds. it h...
implicit and unobserved errors and vulnerabilities issues usually arise in cryptographic protocols and especially in authentication protocols. this may enable an attacker to make serious damages to the desired system, such as having the access to or changing secret documents, interfering in bank transactions, having access to users’ accounts, or may be having the control all over the syste...
