control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

Size Distribution Measurement of Candle\'s Soot Nanoparticles by Using Time Resolved Laser Induced Incandescence

Time resolved laser induced incandescence (LII) technique is used to measure size distribution of soot nanoparticles of candle's flame. Pulsed Nd:YAG laser is used to heat nanoparticles to incandescence temperature and the resulting signal is measured. Mass and energy balance equations are numerically solved to calculate temperature of soot particles in low fluence regime. Assuming Plank black ...

The concept of model transformations is of increasing importance in different areas of Computer Science, but up to now, there is a lack of common understanding concerning the mathematical and practical point of view. In this paper, we discuss some of the different aspects. Especially interesting is the new proposal of the POPL’07 keynote speaker Don Batory claiming that model transformations sh...

Partially Ordered Monoids Generated by Operators H , S , P , and by H , S , P f Are

Let I , H , S , P , Pf be the usual operators on classes of algebras of the same type (Pf for filtered products). The partially ordered monoid generated by the operators H , S , P with respect to composition of operators, I as an identity element, and a natural ordering between operators is described by Pigozzi (Algebra Universalis 2 (1972), 346–353). Let us denote by M = 〈H,S, P 〉 and by Mf = ...
