critical discourse analysis has proved to be of great help in analyzing the form and meaning of literary works. certain scholars such as norman fairclough have greatly improved such studies. the present study deals with one of the political letters of mas'ud i of ghazni to arsalan khan written by his secretary abul-fazl bayhaqi. the complete version of the letter has been recorded in bayhaqi’s ...

In early mathematics development the development of symbolic skills is critical to math learning. Our mathematical system is based on Arabic number symbols which do not provide any semantic meaning relevant to the number words and symbols. In order to succeed in math one must be able to recognize and understand the meaning of numeric and other mathematical symbols. Little is known about the dev...

Let S be the affine plane C together with an appropriate T = C∗ action. Let S be the incidence Hilbert scheme. Parallel to [LQ], we construct an infinite dimensional Lie algebra that acts on the direct sum

In this article, we combine the DLA model of Witten and Sander with ideas from optimal transportation. We propose a modification of the DLA model in which the probability of sticking is inversely proportional to the additional transport cost from the point to the root. We used a family of cost functions parametrized by a parameter α as studied in ramified optimal transportation. α < 0 promotes ...

The acquisition of definite articles has often been related to the acquisition of functional categories (see e.g. Radford, 1990; Clahsen, 1996; Penner & Weissenborn, 1996), since definite articles belong to the functional category (FC) D. Under this view, a problem that remains unsolved is why children pass through a stage in which they produce some definite articles, while at the same time the...

Until ca. 2000, information security was seen as a technological discipline, based on computer science but with mathematics helping in the design of ciphers and protocols. That perspective started to change as researchers and practitioners realized the importance of economics. As distributed systems are increasingly composed of machines that belong to principals with divergent interests, incent...

Based on the Kennaugh-Huynen decomposition, the Target Scattering Vector Model (TSVM) allows to extract four rollinvariant parameters. Those parameters are necessary for an unambiguous description of the target scattering mechanism. The proposed method consists in applying the TSVM prior to the GLRT-LQ detector for the detection of any oriented target.

We prove two cases of a strong version of Dejean’s conjecture involving extremal letter frequencies. The results are that there exist an infinite “ 5 4 + ” -free word over a 5 letter alphabet with letter frequency 1 6 and an infinite “ 6 5 + ” -free word over a 6 letter alphabet with letter frequency 1 5 . 1991 Mathematics Subject Classification. 68R15.
