Finally, we could achieve results which laser irradiation affect crystallization of glass by changing crystallinity between Tx and Tp.
As this reason, there are need to know how much samarium ion affect generating crystallization by heat processing in the glass.
Glass thermal properties were measured by differential thermal analysis (DTA) and thermo mechanical analysis (TMA) at a heating rate of 10 K/min.
Glass stability (∆T = Tg - Tx) is very important factor as well as laser power and laser irradiation time in laser induced crystallization, because it is a factor to determine the crystallization ability from glassy phase.
It is thought laser induced crystallization by samarium heat processing affect nucleation and crystal growth clearly.

For improving control quality of hydraulic actuators, factors affecting system dynamics need to be studied more deeply.
Therefore, just materials properties of hydraulic oil and seals are mathematically modeled.
However, the friction force resists reciprocating motion depends on many factors.
Due to the specific properties of governing equations as mentioned above, directly analytical solving is not a good solution.
It shows that properties of fluid materials effect obviously on system dynamics.

Dielectric properties of the hybrids were also investigated.
CE1 containing 1 wt% of POSS has the best dielectric properties.
Recently, Polyhedral Oligomeric Silsesquioxane (POSS) attracts much attention as one of the most important nano-structured materials owing to its such excellent mechanical properties, thermal stability, and low dielectric constant [3-4].
Our groups have synthesized several different POSS monomers and incorporated them into epoxy and CE to prepare organic-inorganic hybrids with improved mechanical and thermal properties [5-7].
POSS-NH2/CE hybrids were studied in terms of curing reaction and dielectric properties.

The presented solution is the production of fire-resistant building material with improved mechanical properties in comparison with analogues.
As a result of tests in the specialized center "WPC-Test" (Moscow) it was proved that the mineral filler fly ash has a positive effect on the physical and mechanical properties of the material.
Effective Building Materials Based on Wastes of Wood Processing and Metallurgical Industries As a result of the influence of chemical substances and physical factors, the chemical composition of the wood pulp changes, the wood acquires new properties necessary for the production of various building materials and products.
At the heart of the technology of production of wood concrete are complex physical and chemical processes occurring in the wood under the influence of physical, mechanical and chemical factors.
According to the results of the experiments it was also found that the system" Converter slag – Portland cement " is the most effective both in terms of structural characteristics and in terms of mechanical properties [2].

As many factors act simultaneously in the process, it makes it difficult to understand the phenomenon.
Factors which affect slurry erosion depend on operating conditions, eroding particle characteristics, physical and mechanical properties of target material, fluid flow conditions etc.

This shows that the tensile strength is not the only parameter affecting the cracking of concrete under restrained conditions.
Other factors could be: modulus of elasticity, strain capacity and the relaxation of stresses due to creep [4,5].

Therefore, the mechanical properties behaviour of the alloys is very strongly related to their composition and microstructures.
Introduction Ni-based superalloys are widely used for high-temperature applications due to their excellent mechanical properties for high temperature applications.
Therefore, high-temperature mechanical properties of nickel-base superalloys are further enhanced by moderate additions of tungsten.
The overall alloy composition has a role on the mechanical properties of the materials and microhardness measurement is an important parameter to access their strength.
Conclusions The microstructure, phase stability, and mechanical properties of the alloys 70Ni-15Ti-15W and 90Ni-5Ti-5W were examined.

Introduction The dynamic characteristics of the concrete, strictly speaking, are the strain rate dependence of concrete properties.
Obviously, there will be large errors to calculat concrete by static mechanical parameters.
Bischoff [2] DM and Pavlovic (2007) [3] gathered the research results about concrete compressive properties affected by loading rate, such as fracture properties of concrete, strength, elastic modulus, critical strain and Poisson's ratio.
Malvar [4] [5] summarized the research results about uniaxial tensile properties of concrete affected by loading rate.
Dynamic increase factors for concrete.

The aims were to analyze the influence factors and the interaction of these parameters with respect to surface quality produced.
Trimming of composites is different from that of common metal cutting in many aspects, because the composites itself not only inhomogeneous but also dependent on fiber orientation and mechanical properties.
Moreover, P-Value less than 0.05 indicate the factors are significant.

Variations in DOS and HOMO–LUMO gap dictate charge transport and excitonic behavior, significantly affecting stability, band structure, and optical transitions.
The HOMO/LUMO analysis further suggests that SiQDs-2D possess strong potential for optoelectronic applications, where efficient electron transitions and exciton dispersion are critical factors.
