Efficient algorithmic implementation of the Voigt/complex error function based on exponential series approximation

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...

Knot Placement for B-Spline Curve Approximation

Curve approximation still remains one of the di cult problems in CAD and CAGD. One of the key questions in this area is to pick a reasonable number of points from the original curve which can be interpolated with a parametric curve. This paper highlights the use of arc length and curvature characteristics of the given curve to extract the interpolation points. An algorithm is also provided to h...
