Next to weight reduction, lightweight materials like fiber reinforced thermoplastic composites (FRTC) may also improve mechanical properties of vehicle body parts.
Thus they provide the possibility of weight reduction enabling lightweight applications [1].
The scope of this paper is to develop hybrid yarns based on glass fibers and modified nylon 6 fibers that fit the requirements related to processing to fabrics, short flow paths for cycle time reduction during heat pressing and fiber strength.
An evaluation of these data is performed to define the best parameter set for the production of a high amount of hybrid yarns.
In contrast to pressure, a reduction of the average flow path x decreases the process time T by the power of two.

Among them, greenhouse gas emission of coal-fired power generation sector is the main link in coal-energy chain and aslo the focus of regulation and emissino reduction.
The data shows that, at the end of 2010, the total capacity of the national power generation equipment achieved 966.413 million kilowatts, among them, thermal power 704,144,400 kilowatts, accounting for 72.86% of the total installed capacity.

According to the data of China Coal Research Institute in recent years, energy consumption indicators of China's raw coal mined estimates were made: power consumption mining tons of coal 36KWh; raw coal consumed mining tons of coal 30kg.
The data shows that the diesel locomotive proportion of China's railway transport in 2009 is 57.3%, diesel locomotive tons km fuel consumption of 24.6kg / (Wan t • km); the electric locomotive was 42.7%, electric locomotive Wan ton-km power consumption was 111.8kWh / (Wan t • km).

In this work, we study the effect of sintering temperature on the crystal size of CeO2 nanoparticles, which turn in the structural and electrical properties. 1.2 Theoretical part Using XRD data and the Debye-Scherrer equation (Eq. 1), the grain size of CeO2 samples was determined
The pattern of CeO2 agrees with the JCPDS data 34-0394.

Several material constitutive models were developed to match with the experimental data.
Additionally, experimentally measured data were plotted in this figure as a comparison.
Fig. 3b shows a comparison between the IH function and the experimental data obtained from the unixial tensile test for the tested material.
Fig. 4b shows a comparison between calculated cyclic stress-strain curves obtained from three hardening model and the experimentally measured data.
Numerical results were compared with the experimental measurement data to verify the influence of material models on springback prediction.

The calculation data is fitted using the Birch-Murnaghan equation of states (BM-EOS) on Eq. 1 [19].
Previous research generally does not report on data θ2 bond angle.
Tables 1 and 2 tell us that pure anatase has bond length and angle that are not very different from the reference data  [21].
There is no data for the 16% biaxial strain bond length and bond angle because the bonds between atoms in this variation have been broken.
All data from the band gap energy calculation is summarized in Table 3 and Table 4.

The control system allows the recording and archiving of process data, which are collected (on-line) by a PLC and transferred to a PC via Ethernet interface.
Registration and archiving of (on-line) process data are provided by an adaptation of PC software, and the process data from a PLC to a PC via the Ethernet interface are delivered.
An adaptation of PC software may concern the creation of a dedicated software application for the execution of the following tasks: a preliminary analysis of measurement data, a full process visualization, and remote monitoring of process data via a web browser.
The idea of the control system provides long-term achievement of process variables, analysis of process data, mathematical modelling of the process and its remote monitoring.
Moreover, the data constitute an important feedback in processes where the high risk of biofilm formation occurs, which is a general problem concerning industry of almost any type.

The loss of performance due to potential reduction, the time taken for this reduction and the time taken for recovery of the fuel cell performance was investigated by adjusting concentrations of ammonia from 8 ppm to 40 ppm [15].
A computer model based on a MATLAB code (ode45) was performed on the thermodynamic data obtained from JANAF thermochemical tables based on the experimental conditions of 1073 K – 1123 K temperatures and 1 atmospheric pressure to emphasize the advantages of the operating principle and performance of SOFC-H over those of SOFC-O.
Photocatalytic ammonia production allows for the reduction of N2 to NH3 under very mild conditions.
Hence, the efficiency of the electron-hole separation reduction by these metals is less [49]–[51].
Not much data was found for scandium compounds applied in photocatalysis.

First of all, we may use the ability of acquisition and management for powerful spatial decision support system of spatial data and attribute data to rate real estate markets across the country.
Spatial databases use a completely new object-oriented spatial data model-Geodatabase.
The spatial data used by the system is stored in large commercial databases named Oracle with Arc SDE.

From this local data, the objective is to extrapolate as accurately as possible, and thus the choice of a suitable basis is a key point.
Initially, noise polluting the data is not taken into consideration.
From this local data, the idea is then to predict the trajectory for the tool in the remaining part of the domain.
It consists of geometrical data corresponding to the z coordinate of points located on the upper surface of the part.
This information is not measured directly, the raw data must first be processed.

For analytical purposes, the data used was based on a 309 meter distance.
During data collection they were asked to drive in both directions of the road during the day and at night.
The data collection was measured in-vehicle.
