SEPARATION AND IDENTIFICATION OF SIMULATED DIESEL ENGINE NOISE USING INDEPENDENT COMPONENTANALYSIS AND TIME-FREQUENCYANALYSIS

Narayan Time - Frequency Analysis of Diesel Engine Noise

Combustion is the main type of noise radiated from diesel engines. Several methods have been devised to reduce the noise levels. Fourier tranformation methods along with block attenuation curves have been used to study the correlation between cylinder pressure and noise radiated from engines. In this work wavelet method has been used to study noisee mitted from a dual injection diesel engine. T...

functional study of p0 proteins of two cereal yellow dwarf viruses (cydv-rpv and cydv-rps) and identification of their cellular partner

نقش سرکوبگری پروتئین p0 در دو پولروویروس کوتولگی زردی غلات cydv-rpv) و (cydv-rps، متفاوت در شدت بیماریزایی، مورد مطالعه قرار گرفت. نتایج نشان داد که هر دو پروتئین p0 p0cy-rpv) و (p0cy-rps قادر به سرکوب خاموشی آر ان ای ایجاد شده توسط ترادف های تراژن سنس و تکرار معکوس در n. benthamiana هستند. نشان داده شد که هر دو پروتئین p0 می توانند تخریب پروتئین argonaute-1 را تسهیل کنند. علاوه بر این، تمایل م...
