As modeling details can have a large impact on planner performance, domain transformation has been a traditional subject of interest in the planning community not only between languages, but also within languages. Herein, we automate an intra-language transformation method that has as yet been applied only manually, and that has never been formally described: action schema splitting, which tran...

Sinusoidal interferences are found in ultrasonic signals when we try to characterize a material, as for example interferences coming from PC cards. We are interested in obtain a robust method that cancels these interferences preserving the waveform of the signal. A Blind Source Separation BSS method to extract these sinusoids is presented in this paper. We will get so many linear mixtures of th...

the effect of some treatments including preserving solution (20g l-1 sucrose plus 200 ppm 8-hqs), ba and tdz (pulse or spray) with preserving solution were evaluated on senescence parameters and vase life of rose cut flowers cv. red gant. preserving solution, applying 25 mm ba with preserving solution increased solution absorbance, and prevented the cut flowers from getting decreased in relativ...

In this paper, we give a characterization of strongly Jordan zero-product preserving maps on normed algebras as a generalization of  Jordan zero-product preserving maps. In this direction, we give some illustrative examples to show that the notions of strongly zero-product preserving maps and strongly Jordan zero-product preserving maps are completely different. Also, we prove that the direct p...

یک نگاشت خطی t از یک جبر باناخ َ به جبر باناخ إ حافظ حاصلضرب صفر است هرگاه برای هر a,b در a بافرض ab=0 داشته باشیم t(a)t(b)=0 . هدف این پایان نامه بررسی این پرسش است که آیا هر نگاشت پوشا و پیوسته حافظ حاصلضرب صفر یک همریختی وزن دار است؟ نشان میدهیم که پاسخ این سئوال در مورد کلاس بزرگی از جبرهای باناخ شامل جبرهای گروهی مثبت است. روش ما شامل در نظر گرفتن یک نگاشت دو خطی ? از a×a به توی x است(برا...

 Amniotic membrane has been employed in the treatment of wounds for almost 100 years, beginning with early application of natural amniotic membrane obtained from labor and delivery to various types of burns and wounds. Amniotic membrane is rich in collagen and various growth factors that support the healing process to both improve wound closure and reduce scar formation. Unique properties...

For $A,Bin M_{nm},$ we say that $A$ is left matrix majorized (resp. left matrix submajorized) by $B$ and write $Aprec_{ell}B$ (resp. $Aprec_{ell s}B$), if $A=RB$ for some $ntimes n$ row stochastic (resp. row substochastic) matrix $R.$ Moreover, we define the relation $sim_{ell s} $ on $M_{nm}$ as follows: $Asim_{ell s} B$ if $Aprec_{ell s} Bprec_{ell s} A.$ This paper characterizes all linear p...

I Notation: I Ω ⊂ R: domain initially occupied by a material moving under the influence of interior and exterior forces I η ∈ Ω: initial position of an arbitrary particle I x = Φ(η, t): position of particle η at time t > 0 I Ω(t) = Φ(Ω, t): domain occupied by the material at time t > 0 I Basic assumptions: I Φ(·, t) : Ω→ Ω(t) is an orientation preserving diffeomorphism for all t > 0. I Φ(·, 0) ...
