This study examines and formulates the effect of acoustic parameters on the identification of Mandarin Tone2 and Tone3, which are timing of turning point (T_t), falling of F0 (F0_△), duration (T_d), and precursor register (Register). Three stimulus matrixes of tone tokens are set up with T_t and F0_△. Subjects identify tone tokens. In Experiment 1, matrixes are different in T_t or T_t/Td. In Ex...

We describea preciseflameless atomicabsorption spectrometric method requiring only 10 tL ofsample, which thus permits repeated measurements in the neonate. Standard curves covering the range of 0 to 30 mg of zinc per liter, with standards in various matrixes (albumin, glycerol, serum, or nitric acid) hadslopesranging from 0.49 to1.17, relative tothatforaqueousstandards. We prepared low-zinc mat...

This study aims to present a novel approach for determining the weights of decision makers (DMs) based on rough group decision in multiple attribute group decision-making (MAGDM) problems. First, we construct a rough group decision matrix from all DMs' decision matrixes on the basis of rough set theory. After that, we derive a positive ideal solution (PIS) founded on the average matrix of rough...

A novel random-rotation quasi-orthogonal spacetime block code(RR-QO-STBC) transmission scheme is proposed. This transmission diversity scheme randomly rotates every information symbol vector, thus the inter-symbol interference between multi-antennas of QO-STBC is randomized and alleviated. Simulation results suggest, in the high SNR scenario, under the ML detection rule, the proposed scheme out...

in customer relationship management (crm) systems, importance and performance of the attributes that define a service is very important. importance-performance analysis is an effective tool for prioritizing service attributes based on customer needs and expectations and also for identifying strengths and weaknesses of organization in the market. in this study with the purpose of increasing reli...

Solid-phase lipase/metal nanobiohybrids, generated by growth of copper nanoparticles on enzyme matrixes immobilized graphene, were used as heterogeneous catalysts with dual-activity for the regioselective production 2,3,4-triacetyl-D-gluconic acid from α-peracetylated-glucose in a one-pot parallel process combining lipase-mediated hydrolytic monodeprotection metal-catalyzed oxidation aqueous me...

In the formulation of zeolite-based catalysts for direct cracking crude, use kaolin matrixes prevents, to a large extent, zeolite dealumination. Metals and other impurities in crude oil provoke slight decrease activity selectivity patterns.

The reduction of Cu(II) oxide species in siliceous matrixes of different porosity (MFI, FAU, MCM-48) and in alumosilicate MFI was studied by temperature-programmed reduction in hydrogen (TPR), by X-ray absorption fine structure (after stationary hydrogen treatments), and by transmission electron microscopy. It was found that the reduction may proceed in one or in two reduction steps. The two-st...

The methodology developed in this study was based on digital imaging processing of plums harvested eight different weeks during their ripening process. Mean RGB data, histograms, and matrices data were used to characterise the stage plums, both qualitative quantitative approaches, by using classification quantification chemometric methods. An exploratory analysis performed principal component (...
