BACKGROUND Presbyopia if uncorrected causes inability to see and do near work. It is unavoidable as one ages. High school teachers whose work depends much on near work need proper and adequate correction of their presbyopia to increase effectiveness and efficiency. OBJECTIVES The aim was to determine the uptake of correction and prescription for presbyopia of presbyopic teachers of public Sen...

This paper discusses the money demand function in China. We use Cointegration technique and Error Correction Model to estimate the long-run and short -run money demand function. We find that M2 aggregate appears to be cointegrated with price level and income. We also specified a satisfying error correction model for M2.

This study compared the effects of immediate self-correction, delayed self-correction, and no correction on the acquisition and maintenance of multiplication facts by a fourth-grade student with learning disabilities. Data from daily and maintenance tests indicated that both correct response rate and accuracy were higher when self-correction was immediate rather than delayed or absent.

This paper presents a algorithm for the geometric correction of NOAA AVHRR data by using polynomial scan and pixel function. Preprocessings including tangent correction and earth curvature correction can be reduced the order of these functions. Using this method, it was possible to make the geometrically corrected image very fast. Also the precision of geometric correction is discussed.

This paper describes the error correction model that we used for the Automatic Correction of Arabic Text shared task. We employed two correction models, namely a character-level model and a casespecific model, and two punctuation recovery models, namely a simple statistical model and a CRF model. Our results on the development set suggest that using a cascaded correction model yields the best r...

This paper describes the salient features of designing a robust forward error correction coding scheme for satellite data communications and considers various such schemes suitable for a short message application.

A′(n,d,e), the smallest ` for which every binary error-correcting code of length n and minimum distance d is decodable with a list of size ` up to radius e, is determined for all d ≥ 2e−3. As a result, A′(n,d,e) is determined for all e≤ 4, except for 42 values of n.

The effect of atmosphere turbulence on light's spatial structure compromises the information capacity of photons carrying the Orbital Angular Momentum (OAM) in free-space optical (FSO) communications. In this paper, we study two aberration correction methods to mitigate this effect. The first one is the Shack-Hartmann wavefront correction method, which is based on the Zernike polynomials, and t...
