POLLUTION FROM DIESEL ENGINES AND ITS CONTROL Diesel engines and gasoline engines are the most widely used primary sources of power in automobiles and the sheer number of them makes the issue of emissions from these engines an important one. Table 1 gives a comparison of the amounts of different pollutants in the exhaust of diesel and petrol engines. FORMATION OF NOX AND CONTROL METHODS: The main source of NOx in diesel engine emissions is the oxidation of the nitrogen in the air at the high temperatures

the switching rate equals or exceeds the response rate of our human eyes‚ instead of the binary on-off switching‚ our eyes act as “averagers” and the LED is perceived to have “dimmed”. This averaging is analogous to our eyes acting as an RC low-pass filter (see Figure 2). If the switching rate is periodic‚ then the time it takes for a full switching cycle Tswc is given by ! T ≡ T +T ! swc on off (1.1) where Ton is the time the switch is on and Toff is the time that it is off. The frequency

An Application of Structural Filter and Gabor Deconvolution for AVO Processing Jiangbo Yu* and Dong Liu‚ University of Houston Summary This paper discusses two seismic data conditioning processes – Structural Filter (SF) and Gabor deconvolution. We found that these two techniques can improve AVO analysis in CMP and CRP gathers. Structural Filter greatly enhances the S/N of gathers by removing abnormal single high amplitude events‚ outliers and strong random noise. At the meantime‚ the relative
