background: the human seminal fluid is a complex body fluid. it is not known how many proteins are expressed in the seminal plasma; however in analog with the blood it is possible up to 10,000 proteins are expressed in the seminal plasma. the human seminal fluid is a rich source of potential biomarkers for male infertility and reproduction disorder. methods: in this review, the ongoing list of ...

We derive an explicit system of Picard–Fuchs differential equations satisfied by Abelian integrals of monomial forms and majorize its coefficients. A peculiar feature of this construction is that the system admitting such explicit majorants, appears only in dimension approximately two times greater than the standard Picard–Fuchs system. The result is used to obtain a partial solution to the tan...

In this paper the authors relate to the robotic systems to avoid the obstacles while positioning end-effectors. A new strategy to on-line collision-avoidance of the redundant robots with obstacles is presented. The strategy allows the use of redundant degrees of freedom such that a manipulator can avoid obstacles while tracking the desired endeffectors trajectory. The strategy is based on the r...

Fast Fourier Transform (FFT) processors employed with pipeline architecture consist of series of Processing Elements (PE) or Butterfly Units (BU). BU or PE of FFT performs multiplication and addition on complex numbers. This paper proposes a single BU to compute radix-2, 8 point FFT in the time domain as well as frequency domain by replacing a series of PEs. This BU comprises of fused floating ...

Feature selection is a pre-processing technique used for eliminating the irrelevant and redundant features which results in enhancing the performance of the classifiers. When a dataset contains more irrelevant and redundant features, it fails to increase the accuracy and also reduces the performance of the classifiers. To avoid them, this paper presents a new hybrid feature selection method usi...

The conversion of solar energy into electricity makes it possible to generate a power resource at the relevant location, independent availability electrical network. application technology greatly facilitates supply objects that, due their cannot be connected Typical areas use are nature reserves, game management areas, large-scale agricultural livestock industrial pipeline routes, water resour...
