Section 3 contains the main characteristics of the methodology and the development of the elements with their respective Lean tools, as well as a brief compilation of data and metrics for the analysis carried out with the respective analysis tools.
The application of work standardization is facilitated with the VSM tool, a quality management tool that allows identifying processes by opening up opportunities for improvement and waste reduction [22].
Kaizen is a methodology that encompasses procedures for continuous improvement, providing qualitative and quantitative benefits for any manufacturing company, including time and cost savings through a reduction in inventory costs, and improving manufacturing processes [25].
Significant improvements were observed in the following metrics after implementing the model: Current production process efficiency increased from 33.8% to 38.7%, indicating a reduction in operational waste and improved profitability.

The most important feature of a STEM instrument is its versatility: atomic resolution images, nano-beam diffraction patterns and spectroscopy data can be obtained either simultaneously or sequentially from the same region of the specimen [13].

Next, the billets were warm rolled with a reduction of 70% at an initial temperature of 280°C, followed by recrystallization annealing at 520°C in air for 2 h.
(ii) Next, the alloy was cold rolled with a reduction of 80%, followed by recrystallization annealing at 490°C in air for 1 h.
The average density of lattice dislocations was estimated by counting individual dislocations in the grain interiors per unit area on at least six arbitrarily selected typical TEM images for each data point.
An increase in temperature or a decrease in strain rate results in decreasing flow stress and a reduction in initial work hardening; strain, at which the maxim flow stresses are attained, shifts toward higher strains (Fig. 4a).

This can lead to the creation of electrically conductive materials with a minimum consumption of conductive additives, which prevents significant reduction in mechanical performance, caused by eccessive additive volumes [16].
The use of long-fiber chrysotile leads to the destruction of the fibers and reduction of their length.
This determined the reduction of electrical resistance of the fluorohydrite matrix, gauged by sodium phosphate.
Conclusions The obtained data shows that presence of calcium nitrate in the pore solution increases the electrical conductivity of the fluorohydrite composition.

The evident advantage is the significant weight reduction.
Certain improvement could be reached by size reduction of the tiles Fig. 9 and 10.
It has been proved that the combination with technical ceramics can provide significant price reduction in comparison to armour steel while maintaining the same areal weight.

This enables a reduction of the distortion by means of optimized welding sequences without decreasing the productivity.
Thus, on the one hand, for a given seam length and a given welding process, an increase in welding speed results in a reduction of heat input per unit of length and, consequently, of total heat input.
E.g. the so-called back-step method allows the reduction of shrinkage at a sequence of stitch welds.
From its output data one line parallel and one line perpendicular to the seam were taken.

The material data was determined with the layer compression test as the forming processes predominantly exhibit compression stress state.
This causes a reduction of the cup height and results in a wall thickening respectively mould filling of the gear cavity.
To overcome these modes of failure, modifications of the tool regarding a reduction of the punch bottom radius and the drawing clearance would be possible as well as the use of blanks with increased initial sheet thickness.
This is a material and weight reduction of more than 7%.

This reduction in the number of modes needs to be carefully considered when there are strong interactions between modes [6]–[9], because in the case of surface roughness, high-energy modes may affect the transmission at low energies.
The transconductance of Near ballistic with Surface Roughness Scattering SiNW MOSFET device is degrading severely as the gate voltage increases due to the considerable reduction of the mobility along the channel.
Surface Roughness Scattering and Carrier scattering cause reduction of device current.
An Excellent agreement between the modelled and TCAD simulated data was achieved for all the device parameters, so Our proposed approach is appropriate for the modeling of Near Ballistic SiNW MOSFET in the presence of Surface Roughness Scattering.

As for post-anchor stirrup for reinforcement, the bolt’s contributions to shear capacity of concrete beam could adopt the calculation method for bent-up steel bar, referred to the equation (4): (4) Measured values are taken for such items as tensile strength of concrete and yield strength of steel bar and the number of bent-up steel bar n takes that of anchoring stirrup within horizontal range h0, and n=2 is taken for L1, n=3 for l2; bending angle takes 90°; with consideration of the hysteresis phenomenon of strain of bolt in the process of stress, it should be reduced and based on the test results, the reduction factor ξ could take 0.6-0.8, which takes ξ=0.8 for calculation in this paper.
In practice, for the hysteresis phenomenon of stress of post-anchor stirrup, certain reduction of strength of post-anchor stirrup should be taken into consideration, and based on test data, the reduction factor could take 0.6-0.8.
