Also, it is observed that there is a significant reduction in deflection in post-cracking and pre-steel yielding region along with enhancement in the attributes of ductility which is beneficial for serviceability aspects.
Fig. 1 FE model with boundary conditions [2] Fig. 2 Load-deflection response for (a) series II beams and (b) series III beams, derived from experiments and numerical data [2] 3.
The figure establishes a trend which shows that there is significant reduction in deflection with an increase in replacement percentage of steel.

It has been found that the additions of Cu and Zr cause the reduction of the difference of grain size between the hard magnetic phase and the soft magnetic phase, that increase the exchange coupling between them.
The reduction of △Tx would repress the growth of the Fe3B grain which has been crystallization first.
For illustration, the data are also plotted and displayed in Fig 2.

For example, if the building industry wants to realize environmental protection, it must realize energy conservation and emission reduction, and it shall realize environmentally friendly construction on the basis of meeting people’s comfort requirement; faced with such condition, the building industry can only adopt new technology to meet people’s living demand; the building industry shall not only adopt new construction technology, but also carry out certain technological innovation, that is to say, continuously perfecting construction scheme in the construction process so as to meet people’s building requirement; the enterprises can make construction personnel get hold of advanced construction technology only through carrying out construction skill training on construction technical personnel, thus improve core competitive of enterprises.

Lean production as a method of cost reduction which improves the efficiency has been adopted by many SMEs to survive within these dynamic markets.
According to Zhou the main motivator for SMEs to adopt LPS is cost reduction.
Christer Karlsson and Pär Åhlström utilized data from a clinical field study and explored the applicability of the lean enterprise concept and its principles to small and medium-sized firms.
As such, lean production is a method of cost reduction that has been utilized by many SMEs.

Formic acid intercalated Mg-Al layered double hydroxide (Mg-Al Fo-LDH) was prepared by calcination reduction intercalation assembly technology.
In this paper, formic acid intercalated Mg-Al layered double hydroxide (Mg2/Al Fo-LDH) ice melting agent was prepared by using the baking reduction intercalation assembly technology as raw material.
The data were collected in step-scan mode at a scanning rate of 0.02°/s.
Compared with Cl-DIA, Mg2/Al Fo-LDH has a stronger melting ability on the surface ice layer of the asphalt mixture and a better reduction effect on the surface ice layer adhesion.

All data was recorded at 5 min intervals using a data logger.
Data was recorded continuously over 24 h in real ambient conditions.
This result may be caused by the incorporation of Portland cement causing a reduction of the porosity and an increase in the density of the lightweight concretes [11,12].
This leads to a reduction of heat transfer into the inner section of the improved testing room, indicating a better insulating effect of the LWC.

PLA/NR exhibited the lowest Tg (53.9 oC) while the PLA/CSR showed slight reduction of Tg (56.2 oC) as compared to pure PLA (56.3 oC).
The drastic reduction of Tg in PLA/NR blend was attributed to a very low Tg of the NR component (-70oC).
The reduction of Tg for all PLA/rubber blends showed strong influence of rubbery properties of NR, ENR and CSR hence explains the good toughening effect displayed in the blends.

According to data in Table 3, at T10 the PLA/ENR degraded first at 269.6 oC followed by PLA/NR at 275.5 oC and PLA/CSR was slowly degraded at 313.8 oC which were below the T10 of pure PLA (321.3 oC).

M. et al. from RT-SP Computer Based Systems company in Serbia comprehensively took advantage of localization methods based on acoustic energy, time of arrival and angle of arrival, and proposed acoustic localization method based on MLE using those three kinds of measured data [7].
Experimental results showed its localization effects were better rather than only using any one of the three kinds of data.
As we know, both of the parameters and affect signal-to-noise ratio of measured data of sensor nodes.
That is, reduction of parameters or increase of parameter will result in signal-to-noise ratio reduction.
There are 72-76 locations where RMSE values by ASL-LRM method are less than MLE method among the 100 test locations with reduction by 60%-74% at most.
