Introduction
Accurate prediction of the reduction in strength of composite laminates containing notches such
as holes, corners or cracks is a major concern in practice, especially in the design of critical
components for aerospace applications [1].
A reduction in stiffness of components is accompanied by the growth of damage driven by the presence of notches, and ultimate fracture is induced at a lower level of remote stress.
The mechanisms that govern the reduction in strength of composite laminates with notches are more complicated than those of conventional metallic materials.
These unnotched and notched strengths are the average of two data each.

., TiO2, Fe2O3, Al2O3, SiO2) substrates, demonstrate unique catalytic activity for many reactions, such as low-temperature CO oxidation, propylene epoxidation, NO gas reduction, hydrogenation, and SO2 dissociation.
For each simulation, data were collected at the last 50 ps for further analysis.
During the fabrication of gold-TiO2 catalysts, metal hydroxide and/or citrates are used to control the pH and the reduction reaction of Au3+ to metallic Au.
As a result, the AuCl3(OH)- ions from the solution are adsorbed onto the positive sites of the network and then form the gold nanoparticle network upon the reduction reaction.

If the sequence completion time is less than , then directly transferred to the first vehicles to get a new division, and a new division of completion time is strict reduction.
In the first case the transfer can be achieved, and get a new reduction of the maximum completion time strictly.
Table 1 Calculation result It contains: [i1-i2-i3…] represent the path., after [i1-i2-i3…] the data is the arrival time of the last point of the path.
Points From 0 to 4 the shortest time is 46, so regardless of the number of vehicles the balance time of the problem will not be less than 46, and with the reduction of the number of vehicles equilibrium time will be strictly increasing.

The actuator patches are applied to the structural surface and the introduced curvature reduction of the shell is measured.
Fig. 2: Left: cross-section shape contour of sample before and after SMP patch actuation; right: summary of deformation reduction results for different specimen with different number (max. 4) and positions of actuators A considerable improvement in shape accuracy could be achieved.
On the other side, possible creep of the SMP and with that a reduction of actuation forces might be a problem possibly to be overcome by the inclusion of fillers and nano-particles.
These might come from changing communication data density or redirecting radiating beams between different parts of earth.

A reduction in mobility leads to increases in costs to society.
While the State pays a construction premium in advance, the cost savings from reductions in delays, fuel and travel time would apply directly to the traveling public [1].
(4) Calculate Savings by ABC (SAV) -Traffic Delay Reduction SAV (days) = (BCI-C)SAV – (BCI-A)SAV Convert SAV (in days) into $ amount savings
In the absence of actual vehicle count data, the VOC can be estimated conservatively by considering only commercial vehicles (light and heavy trucks) traveling the designated route due to weight restrictions on other county roads in the area.

See table 1 about the tested data.
The content of air entraining agent can reach the air content (≤20%) and also have fine keeping property, i.e. the air content reduction after one hour’s standing can not be more than 4%; at the same time, the compressive strength must reach more than 75% of the reference building mortar.
The mixing of air entraining agent helps reduce the water consumption of building mortar; the increase of air entraining agent means the increase of water reduction. 1.1.3 Relations between the air entraining agent content and compressive strength of mortar As the in crease of air entraining agent content, the compressive strength of mortar goes down. when the air entraining agent content is more than 7.98/100,000, the compressive strength ratio of mortar will be less than 75%.
From the above analysis we can find that the air entraining agent’s influence on mortar performance is: as the increase of air entraining agent, the mortar’s air content will increase and the water consumption will reduce and at the same time the bleeding water will reduce too; while as the reduction of the mortar density, the compressive strength will reduce too. 1.2 Thickening agent’s influence on building mortar performance Another important element in mortar plasticizer is the thickening agent methyl cellulose ester.

· For pursuing their aims every subject effectively uses its own tools for regulating the voltage and available local data about the grid`s mode.
Rules: - If during the regulation of the voltage level by the principle of minimum losses in the adjoining to the node of generation area of the grid increase of the voltage of generator excitation leads to reducing/increasing losses in the grid, then there is proportional increase/ reduction of the excitation voltage
- If during the regulation of the voltage level by the principle of maximum transmission of the electricity in the area of the grid increase of the voltage of generator excitation leads to increase/ reduction in transmission of electricity in the area, then there is proportional increase/ reduction of the voltage of excitation.

The following process parameters were selected based on results of the previous research [11]: an extrusion rate of 0.1 mm/s, an oscillation die frequency of 1.5 Hz and a total reduction degree of 16 (calculated as a ratio of cross section area of the rod before and after the extrusion).
The total thickness reduction of 90 % was achieved in two consecutive rolling passes.
The cold rolling to 90 % of the thickness reduction with an equal speed of both rolls (R=1, ESR) of the KoBo extruded bars leads to a formation of commonly observed in deformed metals microstructural features such as deformation bands.
These results supported by a proper literature data allows concluding that the grain refinement in both the KoBo extrusion and the DSR method is affected by a strain mode and temperature induced activation of a dynamical structure transformation.

So Gauss filter make the characteristic of image blurred during noise reduction.
Preserving the important information such as target edge during noise reduction has been the goal in this domain.
This can reduce diffusion of Gauss filter near the target edge and preserve the edge better during noises reduction.
In the literature [3], a function has been proposed to measure the oscillations in the noisy data and is given below:

A significant reduction in landfilling of ELTs is expected as well, without losing the properties of the traditional concrete.
According to [7], the class of consistency for each average slump values (mean value of two data) was identified.
Referring to Fig. 1a (single layer panel), the steel bar reinforcement was reduced from f5/20 cm to f6/40 cm in the case of RSFC with an overall reduction of 28% per square meter.
In the case of insulated double layer panel, only the non-structural layer was realized with RSFC and the reinforcement of this layer was reduced from f5/20 cm + longitudinal f8/40 cm to f6/40 cm, with an overall reduction of 55%.
