Whereas the feed rate reduction reduces the cut chip thickness resulting in the lesser cutting forces and improved surface finish.
The units are connected by communication channels (connections), which usually carry numeric data, encoded by one of the various ways.
During forward pass, data is read and the weights are fixed at input nodes.

In this respect, it is likely that Ce3+ ions and oxygen vacancies in the samples are responsible for the changes in the Raman scattering as supported by the PL data.
According to the data of the absorption spectrum, the optical band gaps (Eg) of CeO2 nanoparticles can be estimated by using the following equation [26]: (αhν)n=B(hν-Eg), Where α is the absorption coefficient, B is a constant relative to the material, hν is the photon energy, and n is 2 for a direct transition.

Although the variation in leaflet angles of sensitive plant and compaction after folding were examined by using leaf models with experimental data [14], there are generally little researches concerning folding or unfolding manner in plants from mechanical point of view.
By folding with 8 creases, the surface area of the leaf can be reduced to 10 - 20% of an unfolded leaf, although the reduction depends on the number of creases, of course.
From the data of leaf-A in this figure, it is found that very slow initial growth of midrib is accompanied by almost constant growth after.

Morris et al. [3], Lloyd [4] and Westengen [6] interpreted their data in terms of an ultra-fine grained high angle boundary structures.

The main hardening contribution is explained by accounting for the slip length reductions caused by retained low-angle subgrain boundaries.

After that, the ampoule with the cement paste and reference one (empty) was put in the respective channels of the isothermal calorimeter and started collecting data.
It was observed different behavior of the cement paste with 10% w/w in the heat flow (Fig. 3a) and accumulative heat (Fig. 3c), as compared to one without colloidal silica. (4) It was noted similar heat flow of the cement paste in the deceleratory period with a gradual reduction in the rate of heat evolution and probably slow reactions, which also gives rise to calcium silicate hydrate (C-S-H) and calcium hydroxide (CH) formation. (5) The same slow stage period was found involving mainly slow reactions of dicalcium silicate hydration, reducing the porosity and increasing mechanical properties [13].

The coefficients ( )baC , describe the data both in space and scale; a small scaling parameter corresponds to a compressed wavelet function.
The use of the signal quality test based on the wavelet transform usually leads to a substantial reduction in the scatter of experimental points in the measurements of logarithmic decrement, mechanical loss angle, or mechanical damping in general.
Local irregularities (perturbations) in the strain response signal, although they may not be apparent from the measured total response data, are usually discernible from component wavelets.

However, when a compressive load is applied, the insulating layer between the particles decreases and the fillers form a chain of tunnelling paths: this brings about a large reduction in resistance value.
Considering that for soft materials physical quantities such as resistivity and electric field are not constant throughout the sample, piezoresistive data are presented in terms of the electrical resistance as a function of compressive tension.
For a better clarity of the graph, we have only reported the data related to the composites with nickel filler to polymer ratio of 3.5:1 and 5:1, but the results were similar also for the other samples.

It might be the supporting data for indicating that P. ostreatus is the health benefits of functional foods.
Data was subjected to analyses of variance (one-way ANOVA) and corrected by Turkey’s multiple comparisons tests using the GraphPad Prism 7.04 version.

., hybrid and real-time) of an RTHS, the accuracy of the simulated response depends on the employed time step size, analytical substructure model, direct integration algorithm, actuator control and many others, such as, data acquisition and proper functioning of equipments.
On the other hand, a reduction in time step size may require a simpler analytical substructure model which may not capture the realistic behaviour of the system, and thus, it can lead to inaccurate results.
The acceleration vector ( ¨Xn+1), however, can be retrieved from an offline simulation using the RTHS data as shown Block 5 of Fig. 1.
