Abstract The change in water flow required at the BFP pump Barru Power Plant is only regulated by a valve located on pressure side, causing excess power consumption and its own consumption. One effort to save energy usage make frequency adjustments that refer right flow. To determine effect of expected pressure, simulation inverter modeling performed using SPWM switching method based affinity l...

Fractal behavior and long-range dependence have been observed in an astonishing number of physical, biological, geological, and socio-economic systems. Time series, profiles, and surfaces have been characterized by their fractal dimension, a measure of roughness, and by the Hurst coefficient, a measure of long-memory dependence. Either phenomenon has been modeled and explained by self-affine ra...

In this article, we introduce Newtonian spectral clustering, a method that employs Newtonian preprocessing to promote cluster perspicuity and trajectory analysis to gain valuable affinity information. A simple two-body potential is used to model the interaction under the influence of which the points move according to Newton’s second law. This procedure produces a transformed data set with redu...

In this communication we present results concerning a generalization of the preferential attachment (PA) model to heterogeneous complex networks. The PA model by Barabási and Albert constitutes a minimal account of the mechanisms sufficient for the emergence of scale-free networks, characterized by a power-law scaling in their degree distribution. We define a class of heterogeneous PA models, w...

Emotions, a complex state of feeling results in physical and psychological changes that influence human behavior. Thus, in order to extract the emotional key phrases from psychological texts, here, we have presented a phrase level emotion identification and classification system. The system takes pre-defined emotional statements of seven basic emotion classes (anger, disgust, fear, guilt, joy, ...

the term electronegativity .was introduced by linus pauling, who characterized on the basis ofthermodynamic data from the energies of the single bonds. in present study, the density functional theory(dft) was used to calculate electronegativity of atoms. the base of calculation is similar to pauling andmulliken methods. the results indicate that the largest value of electronegativity for fluori...

background: the ability of polyclonal antibodies to react with many epitopes of an antigen makes them valuable reagents in research and diagnosis. the aim of this study was purification of mouse igg2a and production of polyclonal antibody against purified mouse igg2a subclass. materials and methods: mouse igg2a was purified by proa affinity. verification method of the purified antibody was sds-...
