This problem is the same of a large class of non-structural components, such as mechanical and electrical hospital and laboratory equipment that can lose their functionality because of earthquake motions, and structural problem, such as isolated constructions made of superimposed rigid blocks in archaeological areas.
The method of quasi-conservative averaging to obtain the statistical properties and probability distributions for the time to overturning has been recently employed [3].
Under realistic conditions, the rocking response of a rigid block is affected by additional factors such as the vertical component of the ground acceleration and the additional energy loss due to plastic deformations at the pivot points.

Copper fiber has excellent properties such as good thermal conductivity and abrasive resistance.
Take one-dimension materials as reinforcement phase to enhance the properties of matrix material has been reported.
And the reinforcement on friction property by copper powders to resin denoted by following factors [10].Firstly, the improvement on thermal conductivity of copper powders decreases the thermal decomposition of resin, it means that in the friction process, the thermal decomposition loss is reduced.
Thereby, the interface temperature is decreased and the wear resistance properties of polyimide composites would be improved.

The study highlights the difficulty of factors influencing this balance, which is crucial for preventing scaling.
Experimental studies on mineral water have also demonstrated that the calco-carbonic balance significantly influences the properties of water [6].
Few studies have extensively analyzed the factors affecting the Langelier Index in this area, highlighting the need for a more in-depth analysis using robust statistical methods to address this gap[8].
PCA also helped reduce the dimensionality of the data [11], making it easier to identify the key factors influencing the calco-carbonic balance.
Variance Inflation Factors (VIFs) were computed to assess multicollinearity among the predictor variables included in the final regression model.

Optical properties of the touchscreen were assessed using a spectrophotometer to measure the transmitted light over the range of visible wavelengths.
Both the force-resistance profiles and the optical properties of the layer are dependent on the granule loading and composition.
The force-resistance profile and the optical properties of the resulting touchscreen can be controlled by the size and composition of the functional granules in the composite ink.
The optical properties of the ITO/glass substrate and force sensing layer were determined using a spectrophotometer to measure both total transmission and diffuse transmission (haze).

The breaking of these bonds can be affected by a number of factors, including the addition of dopants, synthesis method and thermal treatment [[] M.
These metal ion doping for high temperature stabilization of anatase TiO2 significantly improved the photocatalytic activity of anatase TiO2 since high crystallinity of anatase phase, suitable surface properties such as high surface area, meso-porosity and pore volume are the important factors that contribute to photocatalytic activity of anatase TiO2.
High crystallinity and suitable surface properties such as high surface area, meso porosity and pore volume are also important factors that contributed by the non-metal doping.

These types of connectors were endorsed by experimental push-out tests on hot-rolled steel (HRS) sections, which have different mechanical properties concerning CFS sections, mainly regarding susceptibility to local buckling.
