MAEB: Routing Protocol for IoT Healthcare  [PDF]
Haoru Su, Zhiliang Wang, Sunshin An
Advances in Internet of Things (AIT) , 2013, DOI: 10.4236/ait.2013.32A002
Abstract:

Healthcare is one of the most promising applications of Internet of Things. This paper describes a prototype for the IoT healthcare systems. We propose the Movement-Aided Energy-Balance (MAEB) routing protocol. The movement and energy information of the neighbor Coordinators are collected and stored in the neighbor discovery procedure. The MAEB forwarding is used to select the most suitable neighbor to forward the data. The simulation results show that the proposed protocol has better performance than the other three routing protocols.

Self-Organized Criticality of Rainfall in Central China
Zhiliang Wang,Chunyan Huang
Advances in Meteorology , 2012, DOI: 10.1155/2012/203682
Abstract: Rainfall is a complexity dynamics process. In this paper, our objective is to find the evidence of self-organized criticality (SOC) for rain datasets in China by employing the theory and method of SOC. For this reason, we analyzed the long-term rain records of five meteorological stations in Henan, a central province of China. Three concepts, that is, rain duration, drought duration, accumulated rain amount, are proposed to characterize these rain events processes. We investigate their dynamics property by using scale invariant and found that the long-term rain processes in central China indeed exhibit the feature of self-organized criticality. The proposed theory and method may be suitable to analyze other datasets from different climate zones in China.
Research on Canal System Operation Based on Controlled Volume Method
Zhiliang Ding,Changde Wang
International Journal of Intelligent Systems and Applications , 2009,
Abstract: An operating simulation mode based on storage volume control method for multireach canal system in series was established. In allusion to the deficiency of existing controlled volume algorithm, the improved algorithm was proposed, that is the controlled volume algorithm of whole canal pools, the simulation results indicate that the storage volume and water level of each canal pool can be accurately controlled after the improved algorithm was adopted. However, for some typical discharge demand change operating conditions of canal, if the controlled volume algorithm of whole canal pool is still adopted, then it certainly will cause some unnecessary regulation, and consequently increases the disturbed canal reaches. Therefor, the idea of controlled volume operation method of continuous canal pools was proposed, and its algorithm was designed. Through simulation to practical project, the results indicate that the new controlled volume algorithm proposed for typical operating condition can comparatively obviously reduce the number of regulated check gates and disturbed canal pools for some typical discharge demand change operating conditions of canal, thus the control efficiency of canal system was improved. The controlled volume method of operation is specially suitable for large-scale water delivery canal system which possesses complex operation requirements.
Di-μ-benzoato-κ3O,O′:O′;κ3O:O,O′-bis[aquabis(benzoato-κ2O,O′)(dimethylformamide-κO)europium(III)]
Zhiliang Wang,Xianju Zhou
Acta Crystallographica Section E , 2011, DOI: 10.1107/s1600536811042735
Abstract: The title dimeric complex, [Eu2(C7H5O2)6(C3H7NO)2(H2O)2], is centrosymmetric, implying that pairs of equivalent Eu3+ ions and ligands lie trans to each other and that the two Eu3+ ions have exactly the same coordination environment. Each Eu3+ ion is nine-coordinated by two bidentate benzoate ligands, two bridging tridentate chelating benzoate ligands, and one dimethylformamide and one water molecule. The coordination polyhedron of each Eu3+ ion can be described with a distorted monocapped square-antiprismatic geometry. The molecular structure is stabilized by intra- and intermolecular hydrogen bonds between the water molecules and benzoate O atoms.

The proposed theory and method may be suitable to analyze other datasets from different climate zones in China. 1. Introduction China is not only a big country for its population but also a big agriculture one. Rain is the main source of irrigation water, and it plays a key role in the crop growing period. No rain will cause drought while storm may cause flood. To keep sufficient agriculture production sustainable, it is necessary to identify the role of the rain clearly and to understand the characteristics of the rain deeply. In particular, analyzing the rain in central China is more important because this region is the main crop source and the population density is very high. Rainis liquidprecipitation, as opposed to nonliquid kinds of precipitation such assnow andhail and so on. Rainfall is the result of the atmosphere movement, which is influenced by sun radiation, sea water evaporation, and earth rotation. In the fact, the long-term rain record is a time series which can be regarded as a random process. The rainfall process is actually a complexity system because there are too many influencing factors. In previous studies, many mathematical methods have been applied to find the rainfall pattern, such as periodic, trend, change point, and fractal. Based on the last 1033 years historic data set, Jiang analyzed the temporal and spatial climate variability by using a “Mexican hat” wavelet transform [1]. Bordi used Standardized Precipitation Index (SPI) to assess the climatic condition of this region and applied principal component to capture the pattern of co-variability of the index at different gauge stations [2]. The results suggest that the northern part of east-central China is experiencing dry conditions more frequently from the 1970s onwards indicated by a negative trend in the SPI time series. Applying the binary cubic interpolation and optimal fitting method, Wang et al. set up a statistical model [3]
Substitution of Deoxyinosine as Universal Base in Oligonucleotides for DNA Ligation  [PDF]
Zhiliang Yu
Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.510B090
Abstract:

Oligonucleotides libraries have been developed for various applications, but the library size of oligonucleotide increases dramatically with the addition of oligonucleotide length. To assess the possibility of shortening library size by using universal base, deoxyinosine (dITP), the effect of single/multiple dITP substituted in oligonucleotide on ligation was investigated. It was found that different pairs with dITP had different ligation patterns and pairs with dITP at different locations also showed different ligation patterns. With the departure of substitution position from ligation site, the ligation yield increased. Single dITP substitution at ligation site did extremely hurt the ligation efficiency, except for I:C pair. On the other hand, single substitution at two bases or more apart from ligation site, there is no obvious effect on ligation. Multiple dITP substitutions can more or less affect the ligation, besides I:C pair. This research demonstrated that dITP can be applied to reduce oligonucleotide library size after substitution.

岩石力学与工程学报 , 2004,
Abstract: The system equation for 2D soil consolidation is given and the corresponding program is developed with element-free Galerkin method based on the equilibrium differential equation and the continuous equation of soil,combined with the initial and boundary conditions. In addition,the essential boundary conditions are enforced with penalty method. This method forms the shape functions using the moving least-squares(MLS) polynomial interpolation grounded on a set of arbitrarily distributed points in an influencing domain. Time discretization adopts the Crank-Nicolson integral scheme. The accuracy and feasibility of the EFG method for consolidation problem are verified by comparing the calculation results of a numerical example with those from the analytical method and FEM.

Jizheng Yan,Zhiliang Wang,Yan Yan
Journal of Robotics , 2014, DOI: 10.1155/2014/208924
Abstract: Emotional robots are always the focus of artificial intelligence (AI), and intelligent control of robot facial expression is a hot research topic. This paper focuses on the design of humanoid robot head, which is divided into three steps to achieve. The first step is to solve the uncanny valley about humanoid robot, to find and avoid the relationship between human being and robot; the second step is to solve the association between human face and robot head; compared with human being and robots, we analyze the similarities and differences and explore the same basis and mechanisms between robot and human analyzing the Facial Action Coding System (FACS), which guides us to achieve humanoid expressions. On the basis of the previous two steps, the third step is to construct a robot head; through a series of experiments we test the robot head, which could show some humanoid expressions; through human-robot interaction, we find people are surprised by the robot head expression and feel happy. 1. Introduction Robots play an increasingly important role in our life and work, to assist and even replace the human work in more and more fields. With the development of society, the traditional robots can’t meet human beings, humanoid robots [1–3] are coming, and human beings want more and more analogue. There are many famous humanoid robots, for instance, Kismet and Leonardo made from MIT in USA, ROMAN made in Germany, and WE-robot and SAYA made in Japan, which all could surprise people and give some kind of special feelings but cannot gain some place in person’s awareness. This paper divided these humanoid robots into two domains. First like a beautiful flower vase to people, human beings find it is an amazing thing, and only like to see its actions, for instance, smile, anger; these robots are almost made in Japan and have shocking appearance; second like a toy to people, we find it interesting to play with this kind of robots, which can show some facial expressions, and these robots are always made in USA and Europe. In order to avoid these cases and simplify the whole design, this paper is meant to make a humanoid robot head instead of the whole body, which not only has good appearance, but also can show some expressions. The paper is organized as follows: in Section 1 we introduce two kinds of humanoid robots. In Section 2 we introduce the concept of the uncanny valley. In Section 3 we talk about the Facial Action Coding System (FACS). In Section 4 we design the hardware and software of the robot head and build the robot head according to the previous design.

Ting Liu, Enhao Yang, Zhiliang Wang
Journal of Human Resource and Sustainability Studies (JHRSS) , 2019, DOI: 10.4236/jhrss.2019.72014
Abstract: Income inequality is a serious social economic issue in many countries. The issue is deteriorated due to the complex social environment and demographic composition in the Unites States. This study focuses on the racial and gender factors which influence workers’ income. And the easy-qualified year of schooling and working-year are chosen as the other two factors. Basing on the Ordinary Least Square (OLS) analysis, the selected factors are qualified to understand their influence degree in income inequality. By comparing the coefficients of the factors, we find the inner relationships between the factors and income inequality. The precise results not only provide a chance for people to examine their income levels, but also help the government to develop fair policies.
A theory about induced electric current and heating in plasma  [PDF]
Zhiliang Yang, Rong Chen
Natural Science (NS) , 2011, DOI: 10.4236/ns.2011.34035
Abstract: The traditional generalized Ohm’s law in MHD (Magnetohydrodynamics) does not explicitly present the relation of electric currents and electric fields in fully ionized plasma, and leads to some unexpected concepts, such as ``the magnetic frozen-in plasma'', magnetic reconnection etc. In the single fluid model, the action between electric current and magnetic field is not considered. In the two-fluid model, the derivation is based on the two dynamic equations of ions and electrons. The electric current in traditional generalized Ohm's law depends on the velocities of the plasma, which should be decided by the two dynamic equations. However, the plasma velocity, eventually not free, is inappropriately considered as free parameter in the traditional generalized Ohm's law. In the present paper, we solve the balance equation that can give exact solution of the velocities of electrons and ions, and then derive the electric current in fully ionized plasma. In the case ignoring boundary condition, there is no electric current in the plane perpendicular to the magnetic field when external forces are ignored. The electric field in the plane perpendicular to magnetic field do not contribute to the electric currents, so do the induced electric field from the motion of the plasma across magnetic field. The lack of induced electric current will keep magnetic field in space unaffected. The velocity of the bulk velocity of the plasma perpendicular to magnetic field is not free, it is decided by electromagnetic field and the external forces. We conclude that the bulk velocity of the fully ionized plasma is not coupled with the magnetic field. The motion of the plasma do not change the magnetic field in space, but the plasma will be confined by magnetic field. Due to the confinement of magnetic field, the plasma kinetic energy will be transformed into plasma thermal energy by the Lamor motion and collisions between the same species of particles inside plasma. Because the electric field perpendicular to magnetic field do not contribute electric current, the variation of magnetic field will transfer energy directly into the plasma thermal energy by induced electric field. The heating of plasma could be from the kinetic energy and the variation of magnetic field.
