The tool life at cutting speed of 60m/min is almost twice than that of 120m/min, and the tool life is decreased with the rise of cutting speed, which may attributes to the cutting temperature is increased with the rise of cutting speed at the same time, the high temperature softens the Co adhesive of PCD, which causes the diamond grain spalling from the PCD tools, and the tool wear increases immediately.
At the same time, the number of reinforcement contacting with PCD tools is increased per unit time, which aggravates the tool wear naturally.

Introduction Soil splash erosion is defined as a process of separation, dispersive and migration for soil grains when raindrops hit soil surface, which is an important part of rainfall erosion in natural.

As a prospective new technology, IOT has great potential applications in the management of urban infrastructure including the following aspects: Intelligent Traffic As the increasing number of cars in cities, the traffic becomes more and more heavy.
Moreover, environmental issues can be better tackled, e.g. the carbon footprint of logistics - and supply chains more generally processes can be optimized based on the availability of dynamic, fine-grained data, collected in the real world directly by (or also retrieved with the help of) some of the “things” (such as trucks, pallets, individual product items, etc., depending on the case).

The Drucker-Prager model was considered for the specimen to render the pressure sensitivity and dilation behaviour of concrete. 3D computations allowed defining the number of radial notches for ensuring a homogeneous stress field in the shear zone.
R30A7 concrete is a common concrete containing hard siliceous aggregates with a grain size from 2 to 8 mm, sand, cement and water.

It is only related to the chemical composition and crystal structure of the material, and almost has nothing to do with structural factors, such as grain, orientation and stress distribution.

The contour numbers represent efficiency of power dissipation expressed in percent (η).
On the other hand, the existence of reinforcement is beneficial to the formation of dynamic recrystallized α grain.

However, the volume of all types of pore sharply decreased in number when the eggshell was calcined for more than 1 hour as shown in Fig. 5a.
Nano CaO grain characteristics and growth model under calcination.

The basic task solving time R = T (fi)/IPS+SC (fi) +N (fi), IPS means the number of instructions executed per second by robot.
Compared with the basic load balancing of task, dynamic adjusting has finer-grained control, which allocates tasks after a new task happens or when special event happens.

In order to fundamentally solve the rural fuel problem in mountainous regions and to consolidate the achievements of Grain to Green Programme (GTGP) and Natural Forest Conservation Program (NFCP), the Chinese government has decided to implement the SHPF project.
