This development lead to the construction of the Ultralight Steel Automotive Body (ULSAB) using 90% of high and ultra high strength steel which allows a weight reduction of 25% and an increase in stiffness of 80% [[] Stahl-Informations-Zentrum im Stahl-Zentrum : Ultraleichte Stahlkarosserie.
Figure 3: Contribution of upper tool and lower tool to the compression of the whole tool (left); Extrapolated input data for the numerical simulation (right) At low compression forces up to about 10 kN the percentaged compression of the lower tool is higher compared to the compression of the upper tool, this changes at a compression force of about 15 kN.
Being attended to be used as tabular data in numerical simulation the compression resulting form a compression force is calculated ever 0.5 kN.
In the experiments a compression of the tool of 2.1 mm was necessary to avoid wrinkling which equates a clamping force of 150 kN at the beginning of the forming process if data out of Fig. 3 is used for the calculation of clamping forces resulting from the compression of the whole tool.

Experiments in microgravity provide unique data for testing fundamental theories of grain structure formation.
These data were used to evaluate the 3D-crystallographic orientations of the grains with respect to the solidification direction and to evaluate the distributions of sizes and shapes of the grains in the 2D sections.
For FM1 (and also for FM2) mainly an increase of the solidification velocity from v1 = 0.01 mm/s to v2 = 0.20 mm/s is expected to trigger CET, whereas for FM5 (and also for FM6) a reduction of the temperature gradient is applied.
In future, more experiments on-board the ISS will be performed with different process parameters to broaden the data basis.

Nb promotes the reduction of elasticity modulus [20], increases corrosion resistance [21], and improves the alloy’s biological properties [22].
In principle, the abovementioned findings and data suggest the possibility of producing Ti–Nb alloys with low costs.
Data were collected by an automated system, which basically measures free-decay oscillations [33].
A comparison of the oxygen diffusion coefficients of the Ti–Mo and Ti–Nb alloys with the corresponding data from existing literature is possible only to a limited degree.

Also, the reduction in the quantity of cement in the cement-sand ratio required for quality block production which is done by producers coupled with the cement grade and environmental condition are other factors that affect the quality of sandcrete blocks.

Specimen variation Specimen Binding materials Repair area length [mm] BE - - BGS Grouting mortar + GFRP 2700 BGS-DN4 Grouting mortar + GFRP + 4 anchors dyna-bolt 2700 BGS-DN8 Grouting mortar + GFRP + 8 anchors dyna-bolt 2700 The term existing beam (BE) referred to a normal RC beam filled with ready-mix concrete, where the tensile reinforcing area experienced a 41% reduction due to corrosion.
The TDS-530 data logger automatically records all data obtained from the strain gauge, LVDT, and load cell.
During the test, cracks were observed, and the collected data confirmed that the patterns in all specimens were flexural, as shown in Fig. 12-13.

Due to increased outsourcing in the automotive industry, there is growing demand for communication and data exchanges [5, 7].
Adopting advanced information technology and robust information systems for fast data flows increases information transparency [9].
Challenged by a small and slow-growing domestic market, tariff reductions after accession into the World Trade Organization, and a tight supply of production and technical workers, Taiwanese auto industry firms are restructuring their business activities to better fit the global market [10].
Various manufacturers provide different information models, data formats, systematic structures, and business applications for the logistic activities.

Preceding animal studies of the formulation have shown that the AuNPs preferentially accumulate in solid tumors, resulting in a reduction in tumor size and improved survival [15,16].
The TGA data shown in Figure 3, illustrates a decrease in the thermal degradation temperature of the polymer as it degrades in PBS.
This data suggests that the average concentration was close to 1 wt% but that the local concentration of nanoparticles varied from point to point throughout the polymer matrix.

Surface area was calculated with Brunauer-Emmett-Teller (BET) method using the adsorption data within the p/po range from 0.05 to 0.33.
These data were obtained by irradiating samples via appropriate cutoff filters for the wavelength shown i.e. photon counts decrease with increasing the wavelength.
The reason might be due to a shift of its band edge towards visible light (BE = 2.63 eV) and its fibrous morphology which is responsible to retard the e--h+ recombination process facilitating the reduction process to generate H2.
The crystallite size in the range 3.0–17.5 nm was confirmed from PXRD, FESEM and HRTEM data.

In the subsequent days of the experiment, nothing was done for the experiment besides data collection.
In the paired samples test for CODMn and Chl-a, respectively, it was showed that there were only a significant reduction in AAMs-treated and control groups (Table 2).

In this section, we compare the performance between SIR and Optimized SIR in term of reduction of communication cost and addition of space overhead.
Though our proposal can eliminate or limit a wide range of the known control-plane attacks, it cannot defend the data-plane attack.
The next step of our work is to design the details of the data plane mechanisms to defend the data plane attack in this architecture.
