in this study, scour of mashkid bridge pier located in mashkid river of saravan county has been studied and to measure the scour rate, the numerical model hec-ras 4.0 has been used. upon selection of mashkid river as the case study and whereas the studied zone is important with respect to the climatic conditions and showery monsoon raining and flowing the great and destructive floodwaters, ther...
Abstract In this paper, I regard the Sun-as-a-star magnetic field (i.e., mean field) as a filter for spherical harmonic components of photospheric field, and then calculate transmission coefficients filter. The each harmonic, Y l m , are listed in three tables according to their dependence on B 0 observer’s latitude star’s polar coordinate system. These used interpret 46 yr sequence daily mean-...
determination of mobile localization with time of arrival (toa) signal is a requirement in cellular mobile communication. in some of the previous methods, localization with non-line-of-sight (nlos) paths can lead to large position error. also for simplicity, in most simulations suppose non stationary actual environments as stationary. this paper proposes (residual test + recursive least square)...
"his paper presents a model for channels with memory and applies that model to the process of speciflmg error performance in a digital communications system. A partitioned Markov chain with a single error state is described, based on the well-known Fritchman model, and then applied to error parameters used in perfomance allocation, including bit error rate, error-second rate, block error rate, ...
one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...
we have two part in this thesis, at first: the interaction of native calf thymus dna (ct-dna) with two anthraquinones including quinizarin (1,4- dihydroxy anthraquinone) and danthron (1,8- dihydroxy anthraquinone) in a mixture of 0.04 m brittone-robinson buffer and 50% of ethanol were studied at physiological ph by uv-vis absorption, florescence, circular dichroism spectroscopic methods, viscos...
