avo theory was introduced around 20 years ago. in recent years, this technique was become to a major tool in hydrocarbon sources exploration. by the help of this method with the suitable understanding from underground layers and knowing how to use this technology, quantitative specifications of reservoir can be recognized. avo analysis is a seismic technique that by using of pre-stack data, est...

Each dot represents one company as the intersection of its output (X) and its costs (Y). The solid line (OLS) represents the “Ordinary Least Squares” regression line, which defines the average or expected value of Y (costs) for each value of X (output). It is defined by the intercept, a, and the gradient, b. Without delving into the details of the technique, it amounts to “drawing a line throug...

Penelitian ini dilakukan dengan menerapkan metode Amplitude Variance Frequency (AVF) terhadap data Post Stack Time Migration (3D PSTM ) yang diunduh dari laman Wiki SEG secara bebas. Dekomposisi spektral Continuous Wavelet Transform (CWT) untuk mendapatkan nilai frekuensi bervariasi 25 Hz – 70 per 5 seismik sehingga 10 volume iso CWT kemudian digunakan analisis gradien setelah gathering .

Low probability of intercept radar signals, which are often problematic to detect and characterize, have as their goal ‘to see and not be seen’. Digital intercept receivers are currently moving away from Fourier-based analysis and towards classical time-frequency analysis techniques for the purpose of analyzing these low probability of intercept radar signals. This paper presents the novel appr...

2) It is not true that determination of the "final" creep value from the plot of I/C versus I/~ gives too little weight to the long time creep data and too much weight to the short-time creep data. The opposite appears to be true. The y-intercept (i.e., point_i/~ ÷ 0) is very close (in the horizontal direction) to the points for high t (Fig. 4) and is, therefore, influenced by an error, e I, at...

consider the following consistent sylvester tensor equation[mathscr{x}times_1 a +mathscr{x}times_2 b+mathscr{x}times_3 c=mathscr{d},]where the matrices $a,b, c$ and the tensor $mathscr{d}$ are given and $mathscr{x}$ is the unknown tensor. the current paper concerns with examining a simple and neat framework for accelerating the speed of convergence of the gradient-based iterative algorithm and ...
