The current review article investigates some variables contributing to English language teaching and learning. Three factors of age, motivation and error correction have been of importance in English language curricula in language centres. Some studies have been conducted to investigate various effects of these three components on English language acquisition, those studies, however, may lack d...

In order to correct the image distortion created by the mixing/shear layer, creative and effectual correction methods are necessary. First, a method combining adaptive optics (AO) correction with a digital micro-mirror device (DMD) is presented. Second, performance of an AO system using the Phase Diverse Speckle (PDS) principle is characterized in detail. Through combining the DMD method with P...

A method for file transfer utilizing forward error correction (FEC) to pass traffic over deployed wireless sensor networks is studied. The entire wireless sensor network is modeled as an error-prone virtual physical link. Previous work in the area of terminal communication across the sensor network is expanded upon to include file transfer in order to provide a more capable channel and a basis ...

In order to control the spatial error in the finite element solution of a time-dependent partial differential equation we consider an estimate based upon the error in approximating the time derivative of the dependent variable. It is argued that this is the natural property of the spatial part of the solution to control and, as an illustration, a two-dimensional convection-diffusion problem is ...

A stable mixed finite element method (MFEM) for the second order elliptic problems, in which the scheme just satisfies the discrete B.B condition, is discussed in this paper. The uniqueness and existence of solutions for the corresponding discrete problems are obtained, and the optimal O(h) order error estimates are derived.

objective(s): in spect, the sinogram contains scatter and lack of attenuated counts that degrade the reconstructed image quality and quantity. many techniques for attenuation and scatter correction have been proposed. an acceptable method of correction is to incorporate effects into an iterative statistical reconstruction. here, we propose new maximum likelihood expectation maximization (mlem) ...

-This paper discuss about the method for designing error tolerant systems in SRAM-based FPGAs. SRAM-based FPGAs are preferred in mission based critical space applications. But due to high radiation on the sensitive part of the circuits which introduces errors called Single Event Upset (SEU).Sometimes these types of errors results the permanent malfunction of the entire system. Different error d...

Using the sampled data of a desired pattern is a common technique in pattern synthesizing of array factor (AF) of antenna arrays. Based on the obtained data matrix, Least Square Method (LSM) is used to calculate the exciting coefficient of array elements. The most important parameter, which involves the accuracy and complexity of calculation, is the sampling rate of the desired pattern. Classic...
