In this paper, we examine a modified Cross-Talk Resistant Adaptive Noise Canceller (CTRANC) structure that contains a delay unit on the primary channel to solve the causality constraint of conventional CTRANC. This Asymmetric CTRANC (ACTRANC) structure allows flexible alignment of noise source with the sensors array when the speech source is fixed in its position. Inserting delay unit on the pr...

One of the main controlling parameters in diesel engine combustion is the fuel – air mixing process that has direct effects on engine performance and pollutant emissions, reviewing over previous literature showed that split injection strategies could satisfy this purpose very well. For the first time and in this paper, pilot and double injection strategies were combined and formed new triple in...

A computationally restrained, single-channel, blind dereverberation method is proposed. The proposed method consists of two iterative spectral modifications, which employs spectral subtraction for noise reduction, and a complementary Wiener filter for dereverberation. Modulation transfer function is employed to calculate the dereverberation parameters. Late reverberation is estimated without an...

conventional compression ignition (ci) engines are known for their high thermal efficiency compared to spark ignited (si) engines. gasoline because of its higher ignition delay has much lower soot emission in comparison with diesel fuel. using double injection strategy reduces the maximum heat release rate that leads to nox emission reduction. in this paper, a numerical study of a gasoline fuel...

to study the response of yield,yield components,protein and oil content of soybean cultivars to delay in planting in shirvan region, an experiment was conducted at research farm of the faculty of agriculture, shirvan in 2010. in this study, nine soybean cultivars (habit, hack, black hack, cencutry, cloumbos, clark, sahar, zane and willams) were evaluated at different sowing dates (20 may, 4 jun...

computation of the second order delay in rc-tree based circuits is important during the design process of modern vlsi systems with respect to having tree structure circuits. calculation of the second and higher order moments is possible in tree based networks. because of the closed form solution, computation speed and the ease of using the performance optimization in vlsi design methods such as...
