The initial powders were obtained from soot and amorphous boron by the mechanochemical synthesis method, by the high-temperature synthesis (SHS) method and by the carbon reduction method.
The size of grains on the obtained sample of boron carbide obtained by reduction with carbon does not exceed 20 μm, and the size of the residual pores is about 5 μm.
Aforementioned data correlate with the findings of studies on the effect of nanosized particles on the SPS sintering process.
SEM images of the fractures of hot-pressed boron carbide specimens obtained by various methods: a) SHS method; b) reduction with carbon followed by breaking and grinding; c) mechanosynthesis of amorphous boron and soot; d) direct synthesis during hot pressing.

The main factors behind simulated performance differences are thinner n-channel layer leading to reduced operating voltages and switch to stepper-based photolithography that enables roughly 4-fold layout area reductions for functionally identical circuit blocks.
The Gen. 13 circuit beneficially enables more than 10-fold reduction in simulated maximum power consumption compared to Gen. 12 logic gate, but at the penalty of significantly reduced operating frequency/speed.
For the memory IC designs, Gen. 13 technology more than doubles single-chip data storage capacity.
This is simultaneously achieved while reducing power consumption to less than 1/3rd of the power needed to operate the corresponding Gen. 12 memory chips of much smaller data storage capacity.
Likewise, Table 3 shows even larger degree (> 8X) of power consumption improvement for the Gen. 13 Venus lander and microprocessor circuits compared to Gen. 12 (despite the expansion of the microprocessor’s data/address bus width from 8 bits to 16 bits).

ZigBee transponder is a better choice in terms of data rate and low power consumption as compared to others.
The commands will be received by the encoder and encode this data in proper format, then it will be transmitted to the ZigBee transponder, which will transmit this data using the antenna.
An ARM7 microcontroller processes images and communicates to neighboring motes via transceiver at data rates up to 76.8 kb per second.

The crack growth data of plain specimens exhibited a large scatter, resulting in a difficulty of the measurement of crack growth rate.
Fig. 3 shows S–N plots of the data collected during the stress-controlled fatigue tests.
A white triangle shows the growth data obtained from the DS.
Accordingly, the material constants C1 and n in Eq.(1) can be determined by analyzing the growth data of DS.
The value of n was 5.3 which was determined from the growth data of drilled specimens. 4.

Introduction
Resilient materials used in floor systems play an important role in the reduction of floor impact sound.
By gauging the variables dynamic stiffness and floor impact sound reduction performance changes were also examined.
Through the study results, we aimed to provide basic data for the development of resilient materials, and determine the factors that influenced impact sound insulation performance.
Data for floor impact sound was compiled using a bang machine and measured with a 1/1 octave.

A Structural
Reliability and Risk Assessment (SRRA) software code developed by WOG using input data based
upon the assessed information to quantify the probability of throughwall leak and probability of
break in the line. 937 segments that have consequences are evaluated for failure potential.
The panel reviews all risk informed selection results by utilizing their expertise (including knowledge if prior inspection results, industry data and available stress and fracture mechanics results) and probabilistic safety assessment insights to develop the final categories of high and low safety significant items to be included for inservice inspection.
Reduction in number of Inspection.
On the class 1 piping, 64 NDE inspections will be required resulting in a reduction of approximately 74% from the current requirement of 250 NDE examinations.
Additional 142 NDE examinations of Class 2 piping will be required resulting in a reduction of approximately 76% from the current 592 NDE examinations.

Marginal reduction in bending property has been observed with increase in cycles of impact load.
Flexural strength sUF = (3 Pmax L) /( 2 bh2) (1) Flexural modulus EF = (m L3 ) / (4 bh3) (2) Where, Pmax – maximum load at failure in Newton L - distance between centers of support in metre b - width of the specimen in metre h - thickness of the specimen in metre m - initial slope of the load–deflection curve Data on flexural strength has been acquired for specimen subjected to different cycles of impact loading and the same has been plotted as a graph.
Similar to that of flexural strength, it is seen that up to 2500 cycles, there is a progressive reduction in flexural modulus beyond which it is fairly raises with a mild tip up to 3500 cycles.
Data on flexural strength and flexural modulus have been acquired for different conditions for the sample of GFRP bidirectional laminate and the same are presented in Figs. 4 and 5.
