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...

Optically addressable single-use microfluidic valves by laser printer lithography.

We report the design, fabrication, and characterization of practical microfluidic valves fabricated using laser printer lithography. These optofluidic valves are opened by directing optical energy from a solid-state laser, with similar power characteristics to those used in CD/DVD drives, to a spot of printed toner where localized heating melts an orifice in the polymer layer in as little as 50...

Laser Printer Source Forensics for Arbitrary Chinese Characters

Identifying the source of the printed documents and tracing the printed documents efficiently is a major challenge in lossless document inspecting. As many methods are not independent of the character content, in this paper, a new printer identification method based on the intrinsic printing features of arbitrary Chinese character is proposed. The distinguishing features include the 24-D wavele...

P-177: The Meaning of

Compensation of printer MTFs

Preliminary experiments have shown that the quality of printed images depends on the capacity of the printing system to accurately reproduce details. We propose to improve the quality of printed images by compensating for the Modulation Transfer Function (MTF) of the printing system. The MTF of the printing system is measured using the method proposed by Jang and Allebach, in which test pages c...
