An active design method for the building energy conservation based on modified-self-randomvariation differential evolution algorithm is proposed in order to make the active design for building energy conservation more scientific and reasonable and improve the efficiency of energy utilization of the building and the resident adaptability. Firstly, multivariate linear coefficient model is utilized and the effect of resident activities, meteorological conditions, emergency and other factors is taken into consideration to establish a distributed dynamic model of energy consumption of large-scale public building and then the optimization objectives for the model is given; secondly, research on the biological mechanism of the differential evolution algorithm is conducted to propose a new self random variation mode and give its modified form so as to increase the efficiency of disturbance variation; finally, the experiments on standard test functions and the active design analysis of building energy conservation have verified the effectiveness of the model mentioned herein.

Ethnopharmacological relevance: Semen vaccariae, the seeds of Vaccaria Segatalis, is a famous traditional herb for the treatment of stranguria disease, e.g. benign prostatic hyperplasia (BPH). The present study investigated the effect of crude polysaccharide from Semen vaccariae (SVCP) on BPH in mice in order to further understand the efficacy substance of this medicinal plant. Materials and methods: Sixty healthy adult male Kunming mice were randomly divided into five groups with 12 mice for each group: sham-operated group, BPH model group; BPH model group treated with Pule'an at a dose of 1.20 g/kg; BPH model group treated with SVCP at dose levels of 1.67 g/kg and 0.42 g/kg. The drugs were administered orally once a day consecutively for 12 days. The BPH in mice was created by subcutaneous injection of testosterone propionate for 5 mg/(kg d) to the uncastrated mice once a day consecutively for 12 days. The inhibitory effects on BPH of SVCP were evaluated by prostatic index, testicular index and histopathologic examination. Results: Comparing with BPH model group, BPH mice fed with SVCP exhibited significant differences in both the prostatic index and testicular index. On the aspect of histopathology, the SVCP treated BPH mice exhibited similar histological aspects observed in the mice of sham group while the BPH mice exhibited typical features of prostate glandular hyperplasia. Conclusions: SVCP exhibited a significant inhibitory activity on BPH by reducing the prostatic index, testicular index, and ameliorating the pathomorphology. The results indicated that the polysaccharide should be the main efficacy substance of Semen vaccariae and may contribute, in a large part, to Semen vaccariae's traditional medicinal use for the treatment of stranguria disease. © 2012 Elsevier Ireland Ltd.

The second geometric-arithmetic index GA 2(G) of a graph G was introduced recently by Fath-Tabar et al. [2] and is defined to be mathematical equation representative wnere e = uv 's one edge in G, and nu(e,G) denotes the number of vertices in G lying closer to u than to v. In this paper, we characterize the tree with the minimum GA% index among the set of trees with given order and diameter. As applications, we deduce the trees with the minimum and second-minimum GA 2 index among the set of trees of given order, respectively. In addition, all the trees minimizing the GA 2 index have been shown to have minimum Szeged index and Wiener index, which deduced a result of [7] concerning the Wiener index of trees with given diameter.

The accurate value of battery SOC is one of the prerequisites of a pure electric vehicle energy management to achieve optimal control. However, the battery is a highly nonlinear system and its charge-discharge process is difficult to establish accurate mathematical model. Taking into account nonlinear characteristics of BP neural network, and it has parallel structure and ability to learn, so it is suitable for online estimation of battery SOC value. Train BP neural network through Matlab programming, and predict the performance of the battery based on the built neural network model to get the battery SOC prediction. Simulation results show that the the established BP neural network has good adaptability, and is able to predict the mapping relationship between the battery voltage and SOC. This method is access to battery SOC prediction quickly and easily, the maximum error is less than 1% and the results meet the accuracy requirements. © 2012 IEEE.

This paper is devoted to studying the issue of modeling, forecasting, and optimal feedback control of discrete-time first-order linear stochastic systems with prospective strong intervention (PSI). First, one type of PSI is formulated. Then, one class of induced mechanisms of PSI is characterized, and, with respect to the induced mechanisms, two multi-step forecasting methods for estimating the occurrence time and terminal time of PSI are discussed. Based on these fundamental results, the problem of optimal control with respect to an improved minimum variance performance index is discussed. Finally, the effectiveness and advantages of the proposed control strategy and approach are verified and demonstrated through numerical simulations. © 2014 Chinese Automatic Control Society and Wiley Publishing Asia Pty Ltd.


The objective of Kim (2010) is to give a new delay-dependent full-order robust H∞ filter design method for uncertain discrete-time singular time-delay systems. In the analysis and design procedure, the regularity and absence of impulses of the filtering error system are studied simultaneously. However, an error appeared in the H∞ performance analysis, which is pointed out in this note. © 2015 Elsevier Ltd. All rights reserved.

The stability of impulsive fractional-order systems is discussed. A new synchronization criterion of fractional-order chaotic systems is proposed based on the stability theory of impulsive fractional-order systems. The synchronization criterion is suitable for the case of the order 0 < q ≤ 1. It is more general than those of the known results. Simulation results are given to show the effectiveness of the proposed synchronization criterion. © 2013 Chinese Physical Society and IOP Publishing Ltd.

An approach to finding digital differentiator window functions is studied. The frequency response of the truncated ideal differentiator is expressed by two parts. One is the ideal frequency response and the other is the deviation on the interval from ω = 0 to ω = π. The deviation expression is the sum of weighted functions, where the general expression of these functions is equal to the half-sum of a pair of sinc sum functions plus π, and each weight is a window constant. Using the properties of the sinc sum function eight properties of the general expression and six properties of the deviation expression are deduced. By these properties both the relative errors of the passband and the change of their ripples can be small if each weight is proper and the truncated ideal differentiator is ideal at ω = 0. From the expression of the deviation a matrix equation with window constants as unknowns can be written. Examples are given about how to write the matrix equations and how to find the optimized window constants. Four new differentiator windows as a family are obtained. These windows belong to the fixed window. Different from existing windows, the new windows are optimized in terms of reducing the relative errors of the passband. Comparisons show that new windows are better or much better than the Hanning, Hamming, Blackman, Kaiser, Chebyshev and polynomial windows in terms of differentiator performances. © Springer Science+Business Media, LLC 2012.

This paper investigates the synchronization problem of fractional-order complex networks with nonidentical nodes. The generalized projective synchronization criterion of fractional-order complex networks with order 0 < q < 1 is obtained based on the stability theory of the fractional-order system. The control method which combines active control with pinning control is then suggested to obtain the controllers. Furthermore, the adaptive strategy is applied to tune the control gains and coupling strength. Corresponding numerical simulations are performed to verify and illustrate the theoretical results. © 2012 Chinese Physical Society and IOP Publishing Ltd.

In the title complex, [Mn(C10H7N6) 2(H2O)4], the Mn2+ cation is located on a twofold rotation axis and is coordinated by two N atoms from two 5-[4-(imidazol-1-yl)phenyl]tetrazolide ligands and four O atoms from four water molecules, displaying a distorted MnN2O4 octa-hedral geometry. The crystal structure is stabilized by intermolecular O-H⋯N hydrogen bonds involving the coordinated water molecules and the N atoms of the tetrazolide group.
