Esta investigación metodológica tiene como objetivo definir un concepto de asimetría para variables cualitativas, cuantificarlo y mostrar su validez. Se usó panel cinco jueces expertos simulaciones Monte Carlo. definió el estadístico diferencia promedio frecuencia (dpf) entre pares categorías ordenadas por homogeneidad frecuencia. El dpf mostró comportamiento ajustado a las expectativas con dis...

As a light source for the space gravitational wave detector DECIGO/DPF, we have developed space-borne frequency-stabilized lasers. The light source was an Yb-doped fiber laser with the wavelength of 1030nm. The frequency of the Yb-fiber laser was stabilized in reference to the saturated absorption of iodine molecules so as to suppress the frequency noise down to 1 Hz/rtHz at 1s. We will report ...

Recycling polyethylene terephthalate (r-PET) bottles is a sustainable solution for reducing the accumulation of r-PET in landfills. The primary goal this study to determine viability combining fibers derived from waste and date palm (DPF) produce hybrid unsaturated polyester (UP)-based composites. Hand lay-up was used make UP/r-PET/DPF composites, which had 10%, 20%, 30% by weight, with equal w...

An underwater sensor network (UWSN) has sparse and dynamic characteristics. In UWSNs, the traditional particle filter based on multi-rate consensus/fusion (CF/DPF) problems of a slow convergence rate low filtering accuracy. To solve these problems, tracking algorithm for UWSNs (TASD) is proposed. Firstly, estimation results local are processed by weighted average consensus (WACF). this way, rel...

A chemical mutagenesis to identify zebrafish eye morphological mutants was performed by screening F(3) larvae at 5 and 7 days post-fertilization (dpf) for changes in eye or pupil size. Based on histological analysis, four different phenotypic classes were obtained. The two Class I and three Class II mutants are all characterized by small eyes and exhibit defects in early retinal development or ...

To reduce particulate matter (PM) including soot in diesel exhaust gas, a diesel particulate filter (DPF) has been developed. Since it is difficult to observe the phenomena in a DPF experimentally, we have conducted a lattice Boltzmann simulation. In this study, we simulated the flow in a metallic filter. An X-ray computed tomography (CT) technique was applied to obtain its inner structure. The...

The options for the regeneration of a Diesel Particulate Filter (DPF) using hydrogen rich gas are investigated. The advantages of using hydrogen rich gas for this purpose are described. The system requirements for such a system are also evaluated. The use of a plasmatron fuel converter for the onboard generation of hydrogen rich gas from diesel fuel is discussed. The advantages of homogeneous, ...

We have developed diffraction phase and fluorescence (DPF) microscopy as a new technique for simultaneous quantitative phase imaging and epi-fluorescence investigation of live cells. The DPF instrument consists of an interference microscope, which is incorporated into a conventional inverted fluorescence microscope. The quantitative phase images are characterized by sub-nanometer optical path-l...

This article presents an original dataset of direct public funding (DPF) political parties across 27 post-communist regimes from the outset transition until 2020. It represents first systematic, and detailed account actual level DPF provided to outside established democracies in terms geographical temporal coverage. The has a panel format includes information on per registered voter cast ballot...
