In this paper, we discuss a direct measure for aperiodic energy and periodic energy in speech signals. Most measures for aperiodicity have been indirect, such as zero crossing rate, highfrequency energy and the ratio of high-frequency energy to lowfrequency energy. Such indirect measurements will usually fail in situations where there is both strong periodic and aperiodic energy in the speech s...

introduction energy analysis of agricultural ecosystem is essential for sustainable production. the relation between agriculture and energy is very close. agriculture is an energy consumer and the energy supplier. agriculture’s use of energy is recognized in three external inputs: labor, machines, and fertilizers (connor et al., 2011). significant gains in energy efficiency were arisen in agric...

The modeling of the spectral behavior of the refractive index of AlGaInAs quaternary IIIV semiconductor alloy in the energy range from 0.4 to 4eV, including the transparent region, is presented. The extended model of interband transition contributions incorporates not only the fundamental absorption edge contribution to the dielectric function, but also contributions from higher energy and indi...

The dynamics of electronically excited helium nanodroplets are studied by femtosecond time-resolved photoelectron imaging. EUV excitation into a broad absorption band centered around 23.8 eV leads to an indirect photoemission process that generates ultraslow photoelectrons. A 1.58 eV probe pulse transiently depletes the indirect photoemission signal for pump-probe time delays <200 fs and enhanc...

The modeling of the spectral behavior of the refractive indices of the binary, ternary and quaternary III-V semiconductor alloys in the energy range from 0.2 to 4eV, including the transparent region, is presented. The extended model of interband transition contributions incorporates not only the fundamental absorption edge contribution to the dielectric function, but also contributions from hig...

Both the minimum energy consumption and smoothness, which is quantified as a function of jerk, are generally needed in many dynamic systems such as the automobile and the pick-and-place robot manipulator that handles fragile equipments. Nevertheless, many researchers come up with either solely concerning on the minimum energy consumption or minimum jerk trajectory. This research paper proposes ...

It has been well-established that single layer MX2 (M = Mo, W and X = S, Se) are direct gap semiconductors with band edges coinciding at the K point in contrast to their indirect gap multilayer counterparts. In few-layer MX2, there are two valleys along the Γ-K line with similar energy. There is little understanding on which of the two valleys forms the conduction band minimum (CBM) in this thi...

Abundant evidence indicates that tropospheric specific humidity increases in a warmer atmosphere, at rates roughly comparable to those at constant relative humidity. While the implications for the planetary energy budget and global warming are well recognised, it is the net atmospheric cooling (or surface heating) that controls the hydrologic cycle. Relative humidity influences this directly th...

We are interested in the problem of coherent energy exchange in the spin-boson model augmented with loss, in the limit of infinite loss. This model is interesting because it predicts rapid coherent energy exchange under conditions when the transition energy of the two-level systems is much greater than the characteristic energy of the oscillator. Here we introduce the local approximation, in wh...
