We investigate the viability of a two-stage innationary scenario in the context of super-gravity, so as to resolve the problem of initial conditions for hybrid innation. We allow for non-renormalizable terms in the superpotential and consider the most general form of the KK ahler potential and the gauge kinetic function. We construct a model with two stages of innation, the rst driven by D-term...

Speed humps used as a tool of traffic calming technique that applied to force drivers to reduce their vehicle’ speeds at some locations. For developed countries, the implementations of speed humps are often used within residential areas as well as at locations of schools crossing.  For developing countries (e.g. Iraq), speed humps are used even at urban and urban highways.   This paper investig...

acute respiratory infections, diarrhea and fever are very common in children below the age of five years. all children suffer from these illnesses several times each year. however, during natural disasters like floods children are even more vulnerable to these diseases and death. pneumonia, diarrhea, measles and malaria, and associated malnutrition, are responsible for over 60% deaths in childr...

some 190 specimens of sefidrud loach, oxynoemacheilus bergianus , were collected from aras river (northwestern iran) and age, size, and some biological characteristics of the samples were investigated from march to july 2013. the maximum age was 3 + years. the specimens ranged in size from 42 to 64mm for males and 45 to 61mm for females in total length, weighing from 0.62 to 2.03g for males and...

the objective of the present study was to determine factors affecting body condition score (bcs) and its association with productive and reproductive performances in holstein cows. mixed model analysis was performed on monthly records of bcs from april 2006 to july 2012 comprising 34666 records from 3134 dairy cows in a large commercial dairy herd under arid climatic conditions of isfahan in ir...

We present a formulation for the structured condition number and for the structured backward error for the linear system A Ax = b, when the rectangular matrix A is subjected to normwise perturbations. Perturbations on the data A and the solution x are measured in the Frobenius norm. Numerical experiments that show the relevance of this condition number in the prediction of the computing error w...

Prior condition synchronization primitives for memory transactions either force waiting transactions to abort (the retry construct), or force them to commit (also called punctuation in the literature). Although these primitives are useful in some settings, they do not enable programmers to conveniently express idioms that require synchronous communication (e.g., n-way rendezvous operations) bet...

The talk will present a reliable Krylov-subspace method for estimating the spectral condition number of a matrix A. The main difficulty in estimating the condition number is the estimation of the smallest singular value  min of A. Our method estimates this value by solving a consistent least-squares minimization problem with a known minimizer using a specific Krylov-subspace method called LSQR...
