Typical U.S. children use their knowledge of letters' names to help learn the letters' sounds. They perform better on letter sound tests with letters that have their sounds at the beginnings of their names, such as v, than with letters that have their sounds at the ends of their names, such as m, and letters that do not have their sounds in their names, such as h. We found this same pattern amo...

In models of letter recognition, handwritten letters are considered as a particular font exemplar, not qualitatively different in their processing from printed letters. Yet, some data suggest that recognizing handwritten letters might rely on distinct processes, possibly related to motor knowledge. We applied functional magnetic resonance imaging to compare the neural correlates of perceiving h...

The impact of the Mongol invasions of the Middle East has been the subject of extensive research, especially in the last few decades. Scholars have evaluated the damage and the benefits brought by the Mongols to the Islamic world in different fields such as the military, religion, politics, economy and culture. Despite this, in the case of Anatolia, the Mongol period is still under-studied when...

Some features of SCTP provide opportunities for creating redundancies for signalling over IP networks. This paper presents the behaviour of SCTP in failover scenarios, based on literature review and simulations. Simulations were carried out using NS2 in a multi-homing environment. It was found, as expected, that when failover took place, the undelivered chunks were retransmitted to the secondar...

Rosin, P.L., A note on the least squares fitting of ellipses, Pattern Recognition Letters 14 (1993) 799-808. The characteristics of two normalisations for the general conic equation are investigated for use in least squares fitting: either setting F = 1 or A + C= 1. The normalisations vary in three main areas: curvature bias, singularities, transformational invariance. It is shown that setting ...

The problem of testing equality of several binomial proportions to a speci)ed standard is considered. An exact method of testing based on the test statistic considered in Kulkarni and Shah (Statist. Probab. Lett. 25 (1995) 213) is proposed. Exact properties of the exact method and the approximate method due to Kulkarni and Shah are evaluated numerically for the two-sample case. Numerical studie...

To investigate the use of several preferred retinal loci (PRL) when attempting to read, two patients with bilateral central scotomas were asked to decipher single words, successively projected onto the retina using a scanning laser ophthalmoscope (SLO). Video-recordings of the fundus image, on which the projected targets were superimposed, were analyzed frame by frame. One patient used two PRL ...

Various experimental comparisons of algorithms for supervised classi®cation of remote-sensing images have been reported in the literature. Among others, a comparison of neural and statistical classi®ers has previously been made by the authors in (Serpico, S.B., Bruzzone, L., Roli, F., 1996. Pattern Recognition Letters 17, 1331±1341). Results of reported experiments have clearly shown that the s...
