From the Angle of storage structure of the texture, texture is actually a storage array of two-dimensional image color information, and grain element is composed of color channel.
According to different color channel number and the way of compression, the texture image can be stored for a variety of formats, Creator can support a variety of universal standard image formats, main formats including: contains only one gray channel INT, contains a grayscale channels and a transparency of INTA, including red, green and blue three color RGB channels; Include red, green and blue three color channels and a transparency RGBA; As well as TGA, JPEG, TIF, GIF, BMP format.
The necessary texture memory = the texel size in X direction × the texel size in Y direction × the number of color channels Texture memory is designed for loading and storing texture image memory space, most of the real-time system has a dedicated texture memory, and some real-time system directly to the texture image loaded into the system memory.
The texture mapping of Creator can be divided into the following categories: Put Texture can determine texture mapping by setting the selected three points on the plane and can modify the number of affixed textures to change the elaboration and change the shape of the textures to realize special effects; 4 Point Put Texture can determine the basic differences between texture mapping, function and three-point plane mapping; Surface Project Texture conducts texture mapping to the selected object or plane according to plane and the elaboration of the texture can be adjusted directly; Spherical Project Texture conducts texture mapping from the symmetrical center of the object top and bottom surfaces; Radial Project Texture conducts texture mapping radially from the object top surface center; Geo-Put Texture changes texture shapes according to the ground surface situation so as to perfectly integrate the texture and ground; Environment Map Texture shows the scenes around the object by a pattern

Introduction Numbers of virtual machines (VMs) can be running on the same hardware platform with server virtualization technology [1], which brings serious security hidden troubles [2] as well as convenience.
SELinux is security-enhanced Linux with flexible and fine-grained mandatory access control (MAC) implemented on Linux system.
MAC policy is carried out in SELinux kernel in accordance with the principle of least privilege to make that user programs and system servers only get the minimum number of privileges to meet the needs of performing tasks, with which the potential harm would be greatly weakened or eliminated when user programs and system daemons are being infringed.
However, shown in figure 3, numbers of VMs run in the same server after virtualization so that a malicious VM can directly attack other VMs even the server.

PHAs are bacterial polyesters that are synthetized by a large number of microorganisms under specific cultivation conditions.
PHAs are accumulated intracellularly as carbon and energy storage compound [4] and based on the number of carbon atoms in the monomer unit, these polymers can be classified mainly into two groups: short-chain-length (scl) PHA and medium-chain-length (mcl) PHA.

Number of fatigue cycles of each phase was 1.2×107, and total cycles through both phases were 2.4×107.
Numbers of fatigue cycles in phases 1 and 2 were defined as N1 and N2 respectively.

A number of potential sources can lead to generation of new inclusions, such as reoxidation [1,2] , reaction between steel and runner refractory [3,4], While a number of sources could supply oxygen for reoxidation, the pickup of oxygen by the steel stream from the surrounding atmosphere is one of the most important. [5-7] Industrial studies have evidently shown that using a protective shroud of inert gas such as argon can reduce the number of inclusions and lower the nitrogen as well as hydrogencontents in the steel [8,9] .
The tracing particles , used in this experiment, whose average grain diameter is approximately 5μm, is produced by No.9308 smoke generators assembled by TSI Corporation.

Introduction The grain boundary structure of TiC/Fe cermet sensitively affect its combination of strength and toughness, and experimental results have found that the transition elements (such as Ni, Mo, etc.) adding to TiC/Fe cermets play an important role in improving the interfacial bonding strength and toughness [1-4].
Nslab and Nbulk are the number of formula units contained in the slab and the bulk supercells, respectively.
In Fig. 1 the atoms with numbers 1-7 represent the Ni-doped substitution position as listed in Table 2.
A is the interface area, n is the number of Ni-doped atoms, μNi is the chemical potential of Ni atom taken as a Ni atom energy in Ni unit-cell, μX is the chemical potential of X atom to be replaced by Ni atom.

It was established that, despite the presence of a large number of crystalline compounds in metakaolin, its pozzolanic activity in the absorption of calcium hydroxide from a saturated solution is quite high.
A number of indirect characteristics are used to evaluate the bulk materials’ autohesion, in particular, the angle of repose, which is determined by measuring the contours of the cone formed by the pouring material from the funnel from a certain height (Fig. 1a) or when removing a spatula from a layer of bulk material (Fig. 1 b).
An increase in the number of contacts leads to gel compaction with the dispersion medium (syneresis) release.
It has been established that, despite the presence of a large number of crystalline compounds in metakaolin, its pozzolanic activity in the absorption of calcium hydroxide from a saturated solution is quite high – αCaO=30,1 mg/g в within 50 days.

Due to the difficulty in arrangement of thermocouples, temperature measurement in grinding presents a number of challenges, particularly in high speed cylindrical-plunge grinding.
Meanwhile, as a result of the higher wheel speed, the number of grains involved in cutting became more and the friction between wheel and workpiece intensified, causing the temperature increase.

When number of cycle freezing-defrosting increases, damages of concrete are collected, and its durability decreases.
Scaling of the samples is measured after a well defined number of freeze-thaw cycles and leads to an estimate of the resistance of the tested concrete against frost damage.
The next step is to define relative decreasing in strength of material under different number of term cycles.
Concrete’s frost resistance is defined by number of thermo cycles, which necessary for decreasing in strength in limits, stipulated by the standard.

Fig. 1A shows: before adsorption of CV, PMMT grains are rough, and its dispersion is muddy, slightly yellow, even has precipitation phenomenon with a rest-time of growth.
While LMSH grains are exquisite, and its dispersion is clear, light blue, shows good dimensional stability.
These changes mainly depend on the numbers of exchangeable ions, CV molecule, and the charge distribution between the layers in the same material amount.
On the other, a large number of O atoms and -OH groups exist in the layer surface of PMMT, which also have the ability of surface adsorption. 
On the other, in the end face of LMSH layer, a large number of O atoms and -OH groups exist and can carry on the surface adsorption with CV molecule.
