Introduction. Determining educational needs is the first step in educational planning. Need assessment influences all the decisions regarding educational content, objectives & effective use of resources. To determine the correspondence of educational needs & content in the psychiatry & pediatrics prevalent diseases workshops. Methods. To do this cross- sectional study, 50 physicians participat...

The condition of linear instability for a converging cylindrical shock wave in an arbitrary inviscid medium is obtained. shape resulting front not changed significantly, but the restriction energy cumulation can be caused by exponential grows rotation behind front. correspondence with experimental and simulation data considered.

This paper is devoted to the construction of multi-dimensional schedules for a system of uniform recurrence equations. We show that this problem is dual to the problem of computability of a system of uniform recurrence equations. We propose a new study of the decomposition algorithm rst proposed by Karp, Miller and Winograd: we base our implementation on linear programming resolutions whose dua...

 Recently, Khodabakhshi and Aryavash have introduced a ranking method [Applied Mathematics Letters, 25 (2012) 2066-2070.], which is based on an optimistic-pessimistic approach of data envelopment analysis (DEA). This method ranks all decision making units according to a combination of their minimum and maximum possible efficiency scores which are determined by solving two linear programming mo...

the output on the amplitude of the input in a series of simulations, which showed that the peak and the plateau values of the response are nonlinear monotonic increasing functions of J and nonlinear monotonic decreasing functions of I. Together, these results suggest that the circuit encodes the contrast rather than the absolute amplitude of the input. Fig. 3 shows that the peak and the plateau...

In this paper, we use image moments to solve the problem of estimating deformation fields given a pair of images as input. We use a single family of polynomials to parameterize the deformation field and to define image moments. In this way, variations in image moments can be represented by a set of linear equations. We solve these equations iteratively for the deformation parameters between two...

— This paper begins by comparing Henri Caussinus’ concept of quasi-symmetry with a related but different concept that I shall call Karl Pearson’s quasi-symmetry; and we shall find that Caussinus’ concept is preferable to and more useful than Pearson’s concept. I shall then introduce a set of quasi-symmetric log-bilinear models that are more (∗) Reçu le 18 septembre 2001, accepté le 18 septembre...
