In fed-batch fermentation of glycerol bio-dissimilation to 1,3-propanediol (1,3-PD) by Klebsiella pneumoniae, glycerol and alkali are fed into the reactor to provide nutrient and maintain a suitable environment for cells growth. Taking the feeding process as a time-continuous process, we present a nonlinear multistage dynamical system to formulate the fed-batch fermentation. In view of the big errors between experimental data and computational values, a parameter identification model is established. Finally, an improved Nelder-Mead simplex search method is developed to seek the unknown parameters in the model. Numerical simulations show that the multistage dynamical system can describe the fed-batch process better, compared with the previous results. © 2010 IMACS.

Due to its remarkable approximation ability, neural network is widely applied in pattern recognition, model prediction and data mining. However, the approximation error of neural network at the peak value of the approximated nonlinear function is great, especially the error is greater when the slope difference at both sides of the peak value. An improved rough set-based neural network algorithm is proposed and applied in short-term load forecasting. Taking the load in current time interval, load in prior time interval, load difference between current time interval and prior time interval and current time as the inputs of neural network forecasting model, and the forecasted load in next time interval as the output of neural network forecasting model, the forecasted load, i.e., the output of neural network forecasting model, is compensated according to rough set theory to improve the forecasted result. Simulation results show that using the proposed method the precision of load forecasting can be evidently improved.

Heap sort algorithm is studied thoroughly, a new incomplete heap sort algorithm is designed, and then a novel image median filtering algorithm based on incomplete heap sort algorithm is proposed to improve the filtering speed. The new algorithm considers in detail the characteristic of image median filtering (In median filtering algorithm, the sorting operation of all pixel values is not necessary, getting the median value is the real purpose) and heap sort algorithm, and can give the median value by sorting only part of the pixels value in the neighborhood, thus it can reduce many data move operations, and then greatly improve the efficiency of image median filtering. Algorithm analysis and a lot of experiment results all show that, the new algorithm greatly improves the efficiency of image median filtering, and can keep the edge, outline, texture and much other information to a great extent.

In order to detect coal-gangue interface on fully mechanized mining face, time frequency analysis is applied to the vibration signals of top coal and gangue. This paper introduces short time Fourier transform, wavelet transform and Wigner-Ville distribution to analyze vibration signals under coal mining caving. From the spectrogram, scalogram and smoothed-pseudo Winger-Ville distribution, we can find the short time shock characteristic when coal-gangue caving, which indicates that there are gangues shock to steel plate. Experimental results show that the three time frequency analysis approaches can be used as coal-gangue interface detection well.

The atmospheric turbulence is an important factor which affects the laser atmosphere communication. Particularly, the probability distribution of the light intensity fluctuation is the focus of the research when the laser transfers in the strong turbulence or long distance transmission. And the multi-beam transmission is one of the most important ways to settle the impact on the atmospheric turbulence. This paper takes the negative exponential distribution, I-K distribution as the basis to establish the distribution model of the light intensity under the weak and strong turbulence. Moreover, it uses the test result of related document s for verification. The result shows that the simulation result agrees with the test result relatively; the distribution curve is corresponded; and the degree of fitting is relatively high. With the increase of the beams, the function value for the light intensity distribution is increased; and with the increase of the receiving aperture, the function value for the light intensity distribution is increased.

The connective eccentricity index of a graph G is defined as ξce(G) = ∑ /v ε V (G) d(ν)/ ε(v), where ε(v) and d(ν) denote the eccentricity and the degree of the vertex ν, respectively. In this paper we derive upper or lower bounds for the connective eccentricity index in terms of some graph invariants such as the radius, independence number, vertex connectivity, minimum degree, maximum degree etc. Moreover, we investigate the maximal and the minimal values of connective eccentricity index among all n-vertex graphs with fixed number of pendent vertices and characterize the extremal graphs. In addition, we study the cactus on n vertices with k cycles having the maximal connective eccentricity index.

This paper, by adopting the carbon emission calculating method for all kinds of energy proposed by IPCC in 2006, calculates the amount of carbon emissions of Shandong province. It turns out that carbon emissions in Shandong increased 2.63 times, carbon emission intensity increased 2.45 times and the carbon emission intensity and the energy intensity by GDP is obvious higher than the average level of China from 1997 to 2008.Taking into account the characteristics of carbon emissions in Shandong Province, the paper tries to propose the corresponding strategies to develop low-carbon economy. © 2011 Published by Elsevier Ltd.

Low carbon economy is the inevitable result of the capitalist production model, and is economic development model which mankind is forced to adopt. The measures to reduce carbon emissions mainly include laws and regulations, carbon taxes or carbon trading, subsidies or tax cuts on clean production, technological innovation and demand reduction. These measures have respective advantages and disadvantages. The paper believes that technological innovation and demand reduction are long-term solution of these measures. © 2011 Published by Elsevier Ltd.

This paper investigates the scheduling problem of minimizing makespan on parallel batch processing machines encountered in different manufacturing environments, such as the burn-in operation in the manufacture of semiconductors and the aging test operation in the manufacture of thin film transistor-liquid crystal displays (TFT-LCDs). Each job is characterized by a processing time, a release time and a job size. Each machine can process multiple jobs simultaneously in a batch, as long as the total size of all jobs in the batch does not exceed machine capacity. The processing time of a batch is represented by the longest time among the jobs in the batch. An approximation algorithm with worst-case ratio 2 +ε is presented, where ε >0 can be made arbitrarily small. © 2012 Academy Publisher.
