In this work, I consider an inflation model with a quadratic potential and negative cosmological constant. An analytical solution of the equation motion for inflaton field is found without slow-roll approximation. The result that rolling at constant speed. prediction perturbation calculated.

in this paper the author considers a general method, based on time domain samples for spectral manipulation of time limited signals. first, the original signal is divided into some frames in the time domain. then, by presenting a suitable theoretical and computational algorithm, and using a method for improving the speed of convergence, we find the local bandwidth of each frame; thereby, each f...

Based on the β-estimate that captures interest rate differential effect in uncovered parity (UIP) regressions, we show an empirical model includes proxy variables for unobservable factors and allows to have time-varying weights parameters can reduce UIP deviation. However, specification alleviated failure does not variability of β-estimate. The explanatory exhibit coefficient estimates shifting...

The rate-monotonic algorithm is arguably one of the most popular algorithms for scheduling systems of periodic real-time tasks. The rate-monotonic scheduling of systems of periodic tasks on uniform multiprocessor platforms is considered here. A simple, sufficient test is presented for determining whether a given periodic task system will be successfully scheduled by this algorithm upon a partic...
