a characteristic of modern-time is incorporation of man family life in his individual and social identity, one of the consequences of which is evaluation of family rights with criteria provided in the civil code. while islamic philosophers believe that family has an eminent position, and, to manage it, these philosophers suggest principles which are exclusively applied to family and are differe...

in this paper, efforts are made to compare the safety of steel moment resistant frames designed according to different editions of the iranian code of practice for seismic resistant design of buildings. also, failure risk of a low and medium height frame which designed for high and low seismicity regions according to three editions of the code are evaluated. first, the testing cases were design...

beryllium chemical combination has a considerable effect on the design and fabrication of the241am9be neutron source. in this investigation the beryllium combinations were studied as a generator ofneutrons with various mass percentage, and the neutron yields were also calculated using the results of thealice and srim codes calculations per unit incident charge. the neutron yields of beryllium ...

A xed-length binary code is called t{unidirectional error detecting if no codeword can be transformed into another codeword by at most t unidirectional errors. In this paper we consider the problem of mapping information sequences of length k into code-words of a t{unidirectional error detecting code of length k + p. In case of systematic codes we show that the parameters p and t must satisfy t...

A generalization of Sullivan inequality on the ratio of the probability of a linear code to that of any of its cosets is proved. Starting from this inequality, a sufficient condition for successful decoding of linear codes by a probabilistic method is derived. A probabilistic decoding algorithm for “low–density parity–check codes” is also analyzed. The results obtained allow one to estimate exp...

only linearly and not exponentially with the source block length. Since a trellis approaches a tree as the constraint length grows large, this work also suggests an alternate tree coding scheme and proof of the tree coding theorem of Jakatdar and Pearlman [6]. APPENDIX A The generalized Gallager function Edk(p) is defined in (21). In the following we prove that given RN,* > RN-*(De) for allj an...

abstract memento photographs is the one in which the memory element is more recognizable than any other types of photograph like, snapshot, family photos, personal and domestic ones. in fact the role “memory” is the witness of the time. from the time which camera was invented, its capacity to record the scars of the time made it the popular art among the others. according to the camera’s abilit...
