Two commonly used mathematical expressions to describe the adsorption of gallic acid (GA) on
silica: the Langmuir (eq. 2) and the Freundlich (eq. 3) one, were tested to fit the experimental data:

where Am is the maximum adsorbed amount (mol GA/g SiO2) and KL is the Langmuir equilibrium
constant (l/mol).

Some researches have studied position error of the markers how to affect attitude solving, such as Woltring et al[5] proposed an estimation method of maximum error for solving a given tracking error of the probe when markers is symmetrically distributed on the probe, Morris and Donath el at[6] extended the Woltring’s study and quantify the cumulative impact of multiple sources of error including dynamic deformation error algorithm targets and so on.
The image point of left camera coordinate system in the right coordinate system is as follows VL-R = RLT ×(AL-1×[ul vl 1]T) (5) Where, AL-1×[ul vl 1]T represents image point of markers in the left image coordinate transformating into the left camera coordinate, VL-R indicates that image points in the left camera coordinate are tanrsformating into the right camera coordinate system.

Raoet al.[2] stated that the increase of the depth of cut deteriorates the surface finish of the machined left by the carbide tool.
As M.A Elbestawiet al.,[5] stated in their research, a worn tool produces a better surface finish than a new tool (fresh tools cut well defined scallops resulting in a higher surface roughness).
Q.Liuet al.,[11] flank wear pattern produceswear lands on the side and end flanks of the account of the abrasive action of the machined surface.

Islam et al. [12] analyzed numerically mixed convection in a lid driven cavity with an isothermally heated square blockage and isothermal cold wall temperature imposed on all cavity walls.
Recently, Morshed et al. [13] studied numerically laminar mixed convection in a lid driven square cavity with two isothermally heated square internal blockages.

Zhang et al. developed an ultrasonic machine where the feeding system has a pressure detection function.
Pei et al. drilled hot-pressed silicon nitride, reaction-bonded silicon nitride and magnesia stabilized zirconia using rotary ultrasonic machining with a rotating core drill of metal bonded diamond abrasive while the workpiece being fed towards the core drill at a constant pressure [2].
EL-Wardany et al. studied on monitoring tool wear and failure in drilling using vibration signature analysis techniques [5].
Ghosh et al. fused several signals (i.e., cutting forces, spindle vibration, spindle current and sound pressure) via a neural network to estimate the average flank wear of the main cutting edge in a milling operation [10].

El-Hawary et al. [4] reported the results of experimental research on the durability and performance of various mixtures of RAC incorporating 25% GGBFS as a cement replacement.
Majhi et al. [6] designed six concrete mixes contain 0% ~ 60% GGBFS with each of 50% and 100% recycled coarse aggregate.
Majhi et al. [6] also discussed the mechanical properties and durability of RAC utilising high volume GGBFS (up to 60% replacement ratio of cement) with lime activator.
