A full integral of a polynomial is defined as its integral with the property that any multiple root of the polynomial is a root of this integral. The paper investigates relationships between the existence of a full integral and the form of a polynomial. In particular, it is proved that a ...
The integral image of (x2, y2) corresponds to the summation of pixels from both (x1, y1) and (x2, y2). This implies that the summation of pixels at location (x, y) is the sum of pixels above and left of (x, y). The conversion of the integral image continues until all ...
The 30 keV peak in the X-ray background strongly suggests there should be a large number of highly obscured AGN in the local universe. However, the exact number of these objects remains unknown even though they could nearly double the space density of supermassive black holes. These Compton-...
In order to determine the prediction parameters of probability-integral method and to improve the prediction accuracy, a new method by combining particle swarm optimization algorithm (PSO) and BP neural network (PSO-BP) is presented. In this method, an improved hybrid PSO algorithm is used to op...
In occupational and sports physiology, reduction of neuromuscular efficiency (NME) and elevation of amplitude characteristics, such as root mean square (RMS) or integral of surface electromyographic (EMG) signals detected during fatiguing submaximal contraction are often related to changes in neural drive...
This is consistent with earlier observations using X-ray diffraction for films synthesized with various Ub [21]. Figure 2. Raman spectra of the NiTi surfaces. Order of the spectra (from bottom to top): (1) N/O = 0/1, U = 0 V; (2) N/O = 0/1, U = −100 V; (3) N/O ...

Integrate[1/x^2,{x,-1,1}]结果显示Integral of 1/x^2 does not converge on {-1,1}.我当然知道1/0是无穷,但是这软件算不出来,就把原来的式子重新给我写了一遍,而不是无穷哪个符号,没有结果。还输出了 Integral of 1/x^2 does not converge on {-1,1}....
