An input signal used in process identification-chaos sequence

The sequences which consist of any segment of a chaos sequence are called as C-sequences. These sequences could be used as a kind of input signals to replace M-sequences in the process identification. This substitution is theoretically proved to be feasible. Inverse C-sequences are created in a way similar to inverse M-sequences to solve the problem that C-sequences have nonideal balance property, that is, the numbers of ‘0’ and ‘1’ are unequal. Besides its good pseudo-random property, the sequences have other advantages such as easy to generate, varieties of the segment and adjustable cycle time.     

Statistical analysis on protein-protein interface in crystals： Specific and non-specific interfaces are differentially distributed

The distribution of contact areas, or fractions of contacting, of protein-protein interfaces in crystals of pure polypeptides contains two components: a major exponential distribution and a minor flatter distribution. Suppose the two components belong to specific and non-specific contacts,respectively, then the probability of a contact with a givena rea, or fraction of contacting, can be estimated. By dividing the whole database into two sub-databases, one of them is known to contain more specific contacts than the other, this hypothesis is confirmed and it is also proved that the fraction of contacting is more effective than the contact area on discriminating specific and non-specific contacts in protein crystals.     

Design and Implementation of Hierarchy Cache Using Pagefile

This paper presents a novel hierarchy cache architecture for the purpose of optimizing IO performance. The main idea of the hierarchy cache is to use a few megabytes of RAM and a pagefile to form a two-level cache architecture. The pagefile is equivalent to the cache disk in DCD(Disk Caching Disk). The pagefile outperforms data disks, because data are accessed in different units and different ways. Small writes are collected in the RAM cache first, and data will be transferred to the pagefile in large writes later. When the system is idle, it will destage data from the pagefile to data disks. The performance test results show that the hierarchy cache can improve IO performance dramatically for small writes, and the mail server using the hierarchy cache driver can handle transactions about 2.2 times faster than the normal mail server. The hierarchy cache is implemented as a filter driver, so it‘s transparent to the current Windows 2000/Windows XP operating system.     

Prognosis of residual coal gas capacity made by the ‘Express’ method

An easy, reliable, and inexpensive method, called ‘Express’ method, was described to determine the residual gas capacity of deep mines using results from an air and gas balance. Air and gas balances are common elements of mine management and must be performed periodically. Using the process described here to obtain balance results, it is straightforward to obtain the residual gas capacity, which is an important parameter for decision-making in current mine operations. After a mine is closed, the residual gas capacity becomes a dominant factor used to select methods to protect against gas emissions from the closed underground area or perhaps to provide information for the use of gas reserves. The proposed ‘Express’ method is a much simpler method to obtain the residual gas capacity than other procedures used for this purpose to date.     

Two-Degrees-of-Freedom Decoupling Control for Stable Multivariable Processes

This paper proposes a decoupling control scheme with two-degrees-of-freedom （2DOF） control structure. In the proposed scheme, two multivariable controllers are designed based on Internal Model Control （IMC） theory for setpoint tracking and disturbance rejection independently. An analytical approximation method is utilized to reduce the order of the controllers. By adjusting the corresponding controller parameter, the setpoint tracking and disturbance rejection of each control loop can be tuned independently. In the presence of multiplicative input uncertainty, a calculation method is also proposed to derive the low bounds of the control parameters in order to guarantee the robust stability of the system. Simulations are illustrated to demonstrate the validity of the proposed control scheme.     

Organic-inorganic Polymer Nano-hybrids Based on Sol-gel Reaction

1 Results Nano-ordered composite materials consisting of organic polymers and inorganic materials have been attracting attention for the purpose of the creation of high-performance or high-functional polymeric materials. Especially,the word of "polymer hybrid" claims the blends of organic and inorganic components at nano-level dispersion. By using this idea,an enhancement of mechanical strength of organic polymers with silica particles is possible.High transparency of this material is another important property and indispensable for development of optical waveguides,optical biosensors,non-linear optical materials,and contact lenses. Hybrid materials are also potential candidates for catalysts and gas separation membranes.     

Modeling of Mechanical Behavior of Fractal Rock Joint

The present study shows that naturally developed fracture surfaces in rocks display the properties of self-affine fractals. Surface roughness can be quantitatively characterized by fractal dimension D and the intercept A on the log-log plot of variance: the former describes the irregularity and the later is statistically analogues to the slopes of asperities. In order to confirm the effects of these fractal parameters on the properties and mechanical behavior of rock joints, which have been observed in experiments under both normal and shear loadings, a theoretic model of rock joint is proposed on the basis of contact mechanics. The shape of asperity at contact is assumed to have a sinusoidal form in its representative scale r_c with fractal dimension D and the intercept A. The model considers different local contact mechanisms, such as elastic deformation, frictional sliding and tensile fracture of the asperity. The empirical evolution law of surface damage developed in experiment is implemented into the model to up-date geometry of asperity in loading history. The effects of surface roughness characterized by D, A and r_c on normal and shear deformation of rock joint have been elaborated.     

Contact position controlling for two-dimensional motion bodies by the boundary element method

An algorithm is presented for controlling two-dimensional motion contact bodies with conforming discretization. Since a kind of special boundary element is utilized in the algorithm, the displacement compatibility and traction equilibrium conditions at nodes can be satisfied simultaneously in arbitrary locations of the contact interface. In addition, a method is also proposed in which the contact boundary location can be moved flexibly on the possible contact boundary. This method is effective to deal with moving and rolling contact problems on a possible larger moving or rolling contact region. Numerical examples show effectiveness of the presented scheme.     

Experimental observation of deep crust fluid-NaCl aqueous solution at elevated temperatures and pressures and its significance

In order to reveal the nature of deep crust fluids, the phase relations of NaCI-saturat-ed solution at high temperatures and pressures in a hydrothermal diamond anvil cell (HDAC) are investigated. Salinity of the solutions observed is about 35%-50% . The temperatures for the observation range from 25 to 850℃ and the pressures from 1 atm to about 1 GPa. A supercritical single phase, liquid phase (L), vapor phase (V), solid phase (H), L+H, H + V+L and the near-critical phases L + V can be observed. A two-phase (L + V) immiscibility field for the NaCI solution has been discovered to lie in a wide range of temperatures and pressures: from 250( ±3) to 721℃. Within this field there are two parts, where the upper high temperature part of the two-phase regions is very unstable in character. It is possible to observe a "critical phenomenon". In some of our experiments an "explosion" almost constantly occurred at the interface between the liquid and vapor phases, making the interface obscure, and a continuous transition between the two phases could be found. By a visual microscope it was found that in the two-phase immiscible field near to the critical state the vapor phase and liquid phase compose a crystal structure geometry. It is a special solution structure that was found under a microscope. This discovery is important for us to understand the reason of increasing electronic conductivity of NaCI aqueous solution with respect to temperatures and pressures. And also, it will be easy to interpret the variation of electronic conductivity in the earth crust.     

An Efficient Multidimensional Fusion Algorithm for IoT Data Based on Partitioning

The Internet of Things (IoT) implies a worldwide network of interconnected objects uniquely addressable, via standard communication protocols. The prevalence of IoT is bound to generate large amounts of multisource, heterogeneous, dynamic, and sparse data. However, IoT offers inconsequential practical benefits without the ability to integrate, fuse, and glean useful information from such massive amounts of data. Accordingly, preparing us for the imminent invasion of things, a tool called data fusion can be used to manipulate and manage such data in order to improve process efficiency and provide advanced intelligence. In order to determine an acceptable quality of intelligence, diverse and voluminous data have to be combined and fused. Therefore, it is imperative to improve the computational efficiency for fusing and mining multidimensional data. In this paper, we propose an efficient multidimensional fusion algorithm for IoT data based on partitioning. The basic concept involves the partitioning of dimensions (attributes), i.e., a big data set with higher dimensions can be transformed into certain number of relatively smaller data subsets that can be easily processed. Then, based on the partitioning of dimensions, the discernible matrixes of all data subsets in rough set theory are computed to obtain their core attribute sets. Furthermore, a global core attribute set can be determined. Finally, the attribute reduction and rule extraction methods are used to obtain the fusion results. By means of proving a few theorems and simulation, the correctness and effectiveness of this algorithm is illustrated.     

＂The Flea＂ and ＂A Valediction：Forbidding Mourning＂

John Donne is a representative of 17th century English metaphysical poets.Donne’s poetry embraces a wide range of secular and religious subjects.His poetry is full of philosophical metaphor,and quick thinking activities are lively and strong passions-love passion and the passion of religious integration,which created a new harmony.Reading Donne’s poetry is like participating in a mental game,only use our brains in order to catch up with speeding on the poet’s imagination,his exquisite taste of the speculation.The Flea is one of representative works by John Donne.A Valediction: Forbidding Mourning is the most famous works of Donne’s works.Both "The Flea" and "A Valediction: Forbidding Mourning" are famous love poems by John Donne.The two poems have something in common and something different.Although the two poems are similar and also different to each other,they both set their own situation properly and impressively.     

Effect of coherent-light phase on tunneling process

The coherent-light-driven tunneling in double quantum wells has been studied. The electrons are coupled to a system of phonons and subjected to the two beams of coherently optical waves. By adopting a gauge to both the external field and the phonon field, the phonon field operators in the Schrodinger equations are eliminated. In this way, an expression of the tunneling current is conveniently derived considering the relaxation effect. It is shown that under the intense laser field, the tunneling current oscillates rapidly with time at low temperature. The duration of the oscillations is related to the temperature. By adjusting the phase difference of the two light-beams, the oscillation frequency can be modulated.     

Entransy: its physical basis,applications and limitations

In this paper, the physical basis and application conditions of the entransy theory are reviewed and discussed. Entransy can be obtained from the analogy between heat and electrical conductions. It is a state value and the‘‘potential energy’’ of heat. From the viewpoint of thermomass, it reflects the thermal energy of the thermomass in an object. Furthermore, it was also related to the microstate number and is a single value function of the microstate number. The concepts of entransy, entransy flux and entransy dissipation can be used to express the least action of heat transfer. The entransy balance equations for heat transfer and thermodynamic processes and their applications to thermal systems are also reviewed. The differences between the entransy theory, constructal theory, entropy generation minimization, exergy analyses method, principle of uniformity of temperature difference field and field synergy（coordination） principle are also discussed. The entransy theory is different from the other discussed theories. The limitations of the entransy theory are also discussed.

Simulation and evaluation of the quality and availability of typical GLI ocean image

ADEOS-II satellite will be launched in the near future. It collocates many remote sensing instruments in the same platform. Among them, Global Image (GLI) is considered to be a main sensor which will play a key role. In order to understand the characteristics of future GLI ocean color images, a simulation and evaluation of the quality and availability of GLI typical ocean image has been done. In the paper, we first introduce the simulation models briefly, and simulate typical cases of radiance images at visible channels, in which the radiance distribution is based on geographic location, the satellite orbital parameters and sensor properties. A method, complex signal noise ratio (CSNR) to evaluate the image quality and availability, is developed according to the characteristics of image. Meanwhile, a series of CSNR images are generated from the simulated radiance components for different cases, which can be used to evaluate the quality and availability of GLI images before the ADEOS-II is placed in orbit. Finally, the quality and availability of GLI images are quantitatively analyzed by the simulated CSNR data. The results will be beneficial to the people who are in charge of GLI mission or plan to use the data from GLI.     

组合钢模板在水工隧洞混凝土衬砌施工中的应用

This paper is to explore and analyze the representations of women in Hollywood action films-Kill Bill and Charlie’s Angels.In the former Hollywood action films such as 007,women are often depicted as a foil or assistant to the leading actors.What have been emphasized is their appearance and body;they depend on men and they need to be protected by men.However,in Kill Bill and Charlie’s Angels,women appear to be the leading roles.They become physically strong and they are able to defeat men.However,the women images in these films are still designed to meet the men’s standard,to satisfy their sexual desire towards women,and to reflect their male domination.Part I is a brief introduction of the women images in former action films and offers the thesis statement.Part II concentrates on the marginalized and specialized women images,which provide pleasant sensation to male audiences.Part III is about the male domination reflected in these mentioned films.Part IV focuses on the cinematic ways of shooting used in these films and how the women bodies are exposed in front of the audiences by using these means of shooting.Part V is the conclusion of this paper.     

Lie map for the nonlinear transport of continuous intense beams in the axial-symmetric electrostatic fields

Nonlinear transport of intense continuous beam in the axial-symmetric electrostatic fields is analyzed with the Lie algebraic method. The K-V particle distribution is adopted in the analysis. The results obtained can be used in the calculations of the intense continuous beam dynamics in the beam optical systems consisting of drift spaces, electrostatic lenses, and DC electrostatic accelerating tubes. A computer code has been designed for practical simulations. To meet the needs of accurate calculation, all the elements are divided into many small segments, the electric fields in each segment are regarded as uniform fields, and the dividing points are treated as thin lenses. Iteration procedures are adopted in the code to obtain self-consistent solutions. The code can be used to design low energy dc beam transport systems, electrostatic accelerators, and ion implantation machines.
