Published: February 2014

When wastewater is treated with an electronic water treatment method, hardness, alkalinity and conductivity of the wastewater decrease much slower with time on. If the operating voltage of wastewater treatment is reduced at this time, the purpose of energy saving can be realized while wastewater treatment efficiency is guaranteed. Existing electronic water treatment facilities always realize water treatment with constant low voltages and almost all of them have no optimal design about energy saving, water treatment system rust reduction, water treatment automation, etc. To solve these problems, a new energy-saving electronic water treatment facility is designed in this paper. Based on a low-power SCM MPS430F169 and circuits such as the water treatment voltage control circuit and the voltage and current sampling circuit, the facility establishes a closed-loop system with functions of water quality monitoring and automatic water treatment voltage adjustment. Experimental results show that the facility can realize real-time water quality monitoring in the process of wastewater treatment and automatically adjust operating voltage in line with the water quality, thus significantly reducing unnecessary energy consumption. The facility can be used in fields such as industrial circulating water treatment.

Chaos Control for the Unified Chaotic Systems
Authors: Tian Ling Ling , Li Dong Hai
Published: February 2014

Based on adaptive nonlinear feedback technique, two appropriate controllers are designed to suppress the chaotic behavior of the whole family of the generalized Lorenz system. The derived controllers have nonlinear compensator mechanisms to compensate the system nonlinearities and external disturbances. As a result the output trajectory control is accomplished. According to Lyapunov stability theory the stability analysis of the closed-loop control system is deduced. By numeric simulation, it has been shown that the designed controllers can successfully regulate the chaotic motion of the whole family of the system to a given point or make the output state to track a given bounded signal with great robustness. At the same time the required closed loop behavior is obtained. The most important effect of this letter is that under the actions of the universal controllers deduced from the adaptive technique the problem of chaos suppression of all the Lorenz-type systems can be solved successfully. Moreover the controllers have the ability of attenuating disturbances and the controller parameters are easy to tune according to rigorous analysis of stability. Based on theoretic analysis the designed controllers also provide a heuristic approach for other chaos suppression problems.

Authors: Wu Bo , Feng Yan Peng , Zheng Hong Yan
Published: February 2014

Bayesian reinforcement learning has turned out to be an effective solution to the optimal tradeoff between exploration and exploitation. However, in practical applications, the learning parameters with exponential growth are the main impediment for online planning and learning. To overcome this problem, we bring factored representations, model-based learning, and Bayesian reinforcement learning together in a new approach. Firstly, we exploit a factored representation to describe the states to reduce the size of learning parameters, and adopt Bayesian inference method to learn the unknown structure and parameters simultaneously. Then, we use an online point-based value iteration algorithm to plan and learn. The experimental results show that the proposed approach is an effective way for improving the learning efficiency in large-scale state spaces.

Bit Swap Established on EOC for VDSL
Authors: Liu Chen En , Li Ping
Published: February 2014

With the rapid development of VDSL (Very high-bit-rate Digital Subscriber Line) system, not all the tones have the same margin. In order to cope with the slowly-changing channel, Bit Swap is utilized to swap the tone pairs: the one has a high margin while the other one has a relatively low margin. Although the Bit Swap has been proposed before, there is no Bit Swap established on EOC and the proposed scheme also implements coarse and fine SNR margin tuning. The paper presents the architecture and process of Bit Swap based on EOC and also proposes the method to adjust the margin for tones calculated to be swapped. After thoroughly tested, the test results show that the proposed scheme functions well. Compared with the scheme without Bit Swap, it greatly improves the performance against crosstalk noise and can reduce the RS errors to zero.

NoSQL Database is fit to the management of big data because of the characteristics of high scalability, high availability and high fault-tolerance. And it is one of the technologies of the management of big data. We will improve the performance of massive data processing of NoSQL Database through the large scale data parallel data processing and data localize of computing. So how to allocate the data will be a big challenge of NoSQL Database. In this paper we will propose a data allocation strategy based on the nodes load, which can adjust the data allocation strategy by the execute status of the system. And it can keep the balance of data allocation by a small cost. At last we will use some experiments to verify the effectiveness of the strategy which is proposed in this paper. The experiments show that it can improve the systems performance than other allocation strategy.

By the division of labor cooperation the calculation precision and control speed can be ensured at the same time, thus very strong practicability does the digitized quasi-natural sampling method have.
RETRACTED: Contrasting Active Networks and B-Trees Using Carl
Authors: Zhu Jin , Zhang Shuang
Published: February 2014

Retracted paper: In recent years, much research has been devoted to the emulation of the Turing machine; unfortunately, few have simulated the emulation of the partition table. In fact, few cyberneticists would disagree with the construction of symmetric encryption, which embodies the structured principles of algorithms. We propose a novel heuristic for the synthesis of linked lists, which we call Carl.

Published: February 2014

XML query processing needs to search an XML document and return results that satisfy a request. In this paper, we proposed an effective pattern match algorithm based on structural index. This algorithm uses a suitable labeling scheme and an efficient structural index by identifying parent-child, ancestor-descendant and sibling relationships among nodes. Due to the algorithm avoids invalid immoderate results to be pushed stacks, So, It reduces the amount of joint and improves the performance of Query. Experiment results proved that our algorithm, TwigM performs about 15% better compared to TwigStack [ and 10% better than TwigINLAB[ for all types of queries.

Published: February 2014

Network coding has recently been widely applied in various distributed systems for throughput improvement and/or resilience to network dynamics. However, the computational overhead introduced by network coding operations is not negligible and has become the obstacle for practical deployment of network coding. In this paper, I exploit the computing power of commodity many-core Graphic Processing Units (GPUs) and multi-core CPUs to accelerate the network coding computation. With the implementation of the algorithms, significant encoding and decoding throughput can be achieved.

An Accident Prediction and Diagnosis Method Based on Bayesian Network
Authors: Shi Lin , Li Zhi Gang
Published: February 2014

Against the limitations of some traditional accident prediction and diagnosis methods, a new method based on Bayesian network is proposed on the basis of the Fault Tree Analysis method. Using this method, accident prediction and diagnosis can become easily, quickly and more accurately. The method includes mainly two steps: the first step, to establish Bayesian network topology; the second step, to determine conditional probability table for each node. In addition, to update the marginal probability of the leaf nodes, in order to get a more objective evaluation, changing the past methods which mainly rely on statistics or expert experiences to give the probability value, it proposes an evaluation method using Bayesian network to combine different expert opinions effectively. Finally, taking the gas explosion accident as an example, using GeNIe Software to model and reason, taking analysis of the experimental data, we strive to prove the validity of the model.
