The direct hot charge rolling process can reduce energy consumption, increase production output, and shorted waiting times between production stages, but the integrated planning and scheduling problem for hot charge rolling process was an NP hard. An intelligent integrated planning and scheduling system for direct hot charge rolling process was introduced in this paper. The intelligent system frame and function, especially the integrated planning and scheduling models and the optimization method, have been described in detail. The actual application showed that the solution for integrated planning and scheduling problem of direct hot charge rolling was feasible and effective.

Integrated with performance of disturbance rejection, a new cascade control program is proposed for integrating and delay process based on modified internal model control. Because the set-point tracking and disturbance rejection in the secondary control loop exercise influence on performance of primary loop simultaneously, they are decoupled completely and can be adjusted independently. It realizes two-degree-of-freedom control in the primary loop, and on the basis of stabilizing the integrating process, the controller in the primary loop is devised using the method of minimum sensitivity, which guarantees not only the nominal performance but also the robust stability of the system. Finally, simulations example demonstrates the validity of the proposed control scheme.

This paper presents an optimal method based on combination of artificial potential field (APF) and ant colony optimization (ACO) algorithms for global path planning of mobile robots working in partially known environments. Two steps constitute this approach. Firstly, free space model of mobile robot is established by using visible graph method and ACO algorithm is utilized in this model to search a global collision-free path which is the shortest routine through known static obstacles. Secondly, when unknown obstacles are encountered, APF algorithm is employed to generate a real-time local path so as to avoid collision. Results of simulation experiments show that the proposed approach has good performance in convergence speed, dynamic behavior and is fit for complex environment.

Due to discrepancies in manufacturing process and the probabilistic nature of quantum mechanical phenomenon, faulttolerant architectures are a prerequisite to build reliable nanoelectronic systems from unreliable nanoelectronic devices. Various defects and interference such as doping discrepancies, supply noise and cross-talks could lead to clock irregularity and malformed clock signals in nanoelectronic systems, thus resulting in faulty operations of sequential circuits. As a result, fault tolerance clock distribution is more and more important in nanoelectronic systems. In this paper, a novel architecture for clock recovery is delivered. Very simple circuit is designed for time-to-voltage converter with transforming the error of time to the error of voltage. In order to illustrate the fault-tolerance capability by the detection and recovery circuitry, a prototype CMOS design of this proposed circuit is presented. Simulation shows that the proposed architecture is very suite for integration to nanoelectronic circuit design to realize clock recovery. Keywordstime-to-voltage convertion; self-recovery; faulttolerance; clock

For multi-objective optimization problems, an improved multi-objective genetic algorithm based on Pareto Front and Fixed Point Theory is proposed in this paper. In this Algorithm, the fixed point theory is introduced to multi-objective optimization questions and K1 triangulation is carried on to solutions for the weighting function constructed by all subfunctions, so the optimal problems are transferred to fixed point problems. The non-dominated-set is constructed by the method of exclusion. The experimental results show that this improved genetic algorithm convergent faster and is able to achieve a broader distribution of the Pareto optimal solution.

TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) algorithm is a typical comprehensive evaluation method for ranking the alternatives by similarity to ideal solution. In traditional TOPSIS algorithm, the weights for each evaluation attribute are obtained by questionnaires or expert investment, which reflects the different important degree of each attributes. To overcome the subjective influence on weights, TOPSIS algorithm with optimal weights was proposed in this paper, which calculates the optimal weighting scheme for alternatives by DEA (Data Envelopment Analysis) multiplier model. Our proposed TOPSIS algorithm can identify the distance ratio for each alternative with optimal weights.

The tradition way of recognition of coal-rock interface was usually done by detecting the gamma ray which has several shortcomings such as influence impurities in coal. Moreover, the geological conditions restrictions may have so much influence on the results that may lead this method to out of function. In order to overcome these shortcomings, in this paper the responses of shearer's cutting force was detected to monitor the shearer's cutting state. The response of shearer's cutting force was influenced by multiple factors, such as coal rupture form and working environment. This requires the signal should be processed by using multiple waveforms which can represent multiple factors and finally can find the response of shearer's signal which hide behind the mixed total signal. In order to solve this problem, a multiple scaling functions based multiwavelet algorithm was proposed which can represent the coal-rock interface characteristic signal. A characteristic library was been built by using multiwavelet band energy which can represent the coal-rock response feature of Shearer. By doing numbers of physical simulation tests, it is found that the multiwavelet band energy extract the coal-rock response feature has more advanced than that of the single wavelet analyses. Finally the paper propose a method of detecting the cutting coal-rock state by using Support Vector Machines (SVM) which provide the theoretical basis of the development of simple practical coal-rock Interface Recognition devices.

To assure the accuracy and safety of thermal detection, the thermal flowmeter must be calibrated before using. In order to reduce the uncertainty in a calibration system, the paper presents to build a calibration system for large flowmeter based on the combination of the mass method and master meter method. Meanwhile, the system simulation, monitor function and data process will be achieved through Lab VIEW basing on NI's Virtual Instruments. This method can avoid the large error due to the using of mass method or master meter method separately. It is helpful to improve the autoimmunization degree and reduce the uncertainly of the results during the measuring process.
