Abstract Nanosecond surface dielectric barrier discharges (ns-SDBDs) are a class of plasma actuators that utilize high-voltage pulse nanosecond duration between two surface-mounted electrodes to create an electrical breakdown air, along with rapid heating. These usually produce multiple filaments when operated at high frequencies, and the heating leads formation shock waves complex flow fields....
this study considers the level of increase in customer satisfaction by supplying the variant customer requirements with respect to organizational restrictions. in this regard, anp, qfd and bgp techniques are used in a fuzzy set and a model is proposed in order to help the organization optimize the multi-objective decision-making process. the prioritization of technical attributes is the result ...
The Continuous Wavelet Transform (CWT) has been recently proposed to model f0 in the context of speech synthesis. It was shown that systems using signal decomposition with the CWT tend to outperform systems that model the signal directly. The f0 signal is typically decomposed into various scales of differing frequency. In these experiments, we reconstruct f0 with selected frequencies and ask na...
abstract evapotranspiration (et) determination is a key factor for irrigation scheduling, water balance, irrigation system design and management and crop yields simulation. therefore many scientists have tried to estimate evapotranspiration in different spatial and temporal scales. remote sensing is a one of new technique in estimation of et in regional scales. so, in this study it’s tried to e...
Post-traumatic stress disorder (PTSD) patients have high scores on F and low scores on K scales of MMPI. The higher F scors than K scores show that they overreport their symptoms and problems. 128 subjects in four groups (32 in each group) were selected for the study. The groups included: A) out - patients combatants with PTSD (with mean age of 28) B) combatants without any psychiatric problem ...
abstract amino acids are building blocks of proteins, and play a vital role in living beings existence and their functionality. the interaction of these compounds with metal ions is of great importance to biochemists, and chemists, because their functions can be utilized as a model in understanding enzymes mechanism for transport of metal ions to tissues. among twenty essential amino acids w...
The spatiotemporal dynamics of the solar photosphere is studied by performing a proper orthogonal decomposition (POD) of line of sight velocity fields computed from high resolution data coming from the MDI/SOHO instrument. Using this technique, we are able to identify and characterize the different dynamical regimes acting in the system. Low-frequency oscillations, with frequencies in the range...
