Line spectral frequencies (LSF) are widely used in the field of speech coding. Due to its properties, the LSF are qualified for the quantisation and the efficient compression of speech signals. In this paper we introduce the line cepstral quefrencies (LCQ). They are derived from the cepstrum in the same manner as the LSF are derived from linear predictive coding (LPC) features. We show that the...

در آشکار‌ساز CMS نسبت‌های انشعاب بوزون هیگز مدل استاندارد به جفت‌‌های J/ψ(1S) و cc ترتیب برابر 2-10×1/8 2-10×2/89 اندازه‌گیری شده است. لحاظ نظری یکی از سناریوهای ممکن برای تولید مستقیم این است که آغاز جفت واپاشی نماید سپس مرحله‌ی بعد هر یک کوارک‌های c طور مزون ترکش کنند. بر اساس سناریو مقاله بطریق کوارک‎های با استفاده نظریه اختلال مکانیک کوانتومی رنگ (pQCD) نظر گرفتن حالت‌های قطبش طولی عرضی محا...

The pulsed-field gel electrophoresis (PFGE) pattern of SmaI digests of 29 strains of Lactococcus lactis subsp. lactis and subsp. cremoris were determined. Unrelated strains yielded markedly different patterns of digestion products. Bacteriophage-resistant derivatives of four strains, generated by a method analogous to that used regularly in some cheese factories, yielded patterns that were iden...

We show that a recently introduced Lax pair of the Sawada-Kotera equation is nota new one but is trivially related to the known old Lax pair. Using the so-called trivialcompositions of the old Lax pairs with a differentially constrained arbitrary operators,we give some examples of trivial Lax pairs of KdV and Sawada-Kotera equations.

the present study, on the one hand, attempted to investigate the strategies applied in dispreferred responses by iranian university students of english and the extent to which pragmatic transfer could occur.  on the other hand, the study aimed to probe into the association between dispreferred organization and turn-shape. to this end, 31 relevant naturally occurring conversations, totaling 120 ...

in searching a market-neutral arbitrage strategy in forex market, we took a portfolio of three major currency pairs, eur-usd, usd-jpy, and eur-jpy. there are eight approaches, different cases of short and long positions; for example buying 1st and selling two others, etc. historical daily fx rates were gathered since january 1990 until february 2011. monthly covariances between daily growth rat...

Submodularity is an important  property of set functions with deep theoretical results  and various  applications. Submodular systems appear in many applicable area, for example machine learning, economics, computer vision, social science, game theory and combinatorial optimization.  Nowadays submodular functions optimization has been attracted by many researchers.  Pendant pairs of a symmetric...

‎the frobenius complement of a given frobenius group acts on its kernel‎. ‎the scheme which is arisen from the orbitals of this action is called ferrero pair scheme‎. ‎in this paper‎, ‎we show that the fibers of a ferrero pair scheme consist of exactly one singleton fiber and every two fibers with more than one point have the same cardinality‎. ‎moreover‎, ‎it is shown that the restriction of a...
