需求响应潜力的准确评估是电网调度部门制定科学合理调度计划的数据支撑,对于需求响应实施过程中涉及的各个利益主体均有重要意义。由于工业负荷用电量大且用电规律,其可挖掘的调节潜力巨大,是最理想的需求响应资源之一。首先,针对典型可调节用户,聚类分析其主要用电计划类型,并根据最大相关最小冗余准则对各用电计划进行画像;然后,以典型可调节用户不同用电计划的数据集作为训练集进行负荷超短期预测,得到典型用户在调度时段的可调节容量;最后,基于所提出的园区响应潜力评估框架,根据用电行为聚类确定各工厂所属典型可调节负荷类别,并根据各类型可调节负荷占比得到园区内对应类型负荷的可调节容量,进而得到园区总体的调节潜力。仿真结果表明,所提评估方法可分析出园区内各类可调节负荷的调节潜力,并结合园区总调节潜力的实际数据验证了评估方法的有效性。

Impulsive effect on exponential synchronization of neural networks with leakage delay under sampled-data feedback control

引用

Chinese Physics B 2014年第7期23卷 218-229页

作者： S.Lakshmanan ju H.park Fathalla A.Rihan R.Rakkiyappan Department of Mathematical Sciences College of ScienceUAE University Nonlinear Dynamics Group Department of Electrical EngineeringYeungnam University Department of Mathematics Bharathiar University

We consider the impulsive effect on the exponential synchronization of neural networks with leakage delay under the sampled-data feedback control. We use an appropriate Lyapunov-Krasovskii functional combined with the input delay approach and some inequality techniques to derive sufficient conditions that ensure the exponential synchronization of the delayed neural network. The conditions are formulated in terms of the leakage delay, the sampling period, and the exponential convergence rate. Numerical examples are given to demonstrate the usefulness and the effectiveness of the results.

AIM：To evaluate the effect of exogenous recombinant human bone morphogenic protein-7（rhBMP-7）on transforming growth factor-β（TGF-β）-induced epithelial mesenchymal cell transition（EMT）and assessed its antifibrotic effect via topical ***：The cytotoxic effect of rhBMP-7 was evaluated and the EMT of human corneal epithelial cells（HECEs）was induced by TGF-β. HECEs were then cultured in the presence of rhBMP-7 and/or hyaluronic acid（HA）. EMT markers,fibronectin,E-cadherin,α-smooth muscle actin（α-SMA）,and matrix metaloproteinase-9（MMP-9）,were evaluated. The level of corneal fibrosis and the reepithelization rate were evaluated using a rabbit keratectomy model. Expression of α-SMA in keratocytes were quantified following treatment with different concentrations of ***：Treatment with rhBMP-7 attenuated TGF-β-induced EMT in HECEs. It significantly attenuated fibronectin secretion（31.6%; P〈0.05）,the α-SMA protein level（72.2%; P〈0.01）,and MMP-9 expression（23.6%,P〈0.05）in HECEs compared with cells grown in the presence of TGF-β alone. E-cadherin expression was significantly enhanced（289.7%; P〈0.01）in the presence of rhBMP-7. Topical application of rhBMP-7 combined with 0.1% HA significantly reduced the amount of α-SMA~＋ cells by 43.18%（P〈0.05）at a concentration of 2.5 μg/mL and by 47.73%（P〈0.05）at 25 μg/mL,compared with the control group,without disturbing corneal ***：rhBMP-7 attenuates TGF-β-induced EMT in vitro,and topical application of rhBMP-7 reduces keratocyte myodifferentiation during the early wound healing stages in vivo without hindering reepithelization. Topical rhBMP-7 application as biological eye drops seems to be feasible in diseases involving TGF-β-related corneal fibrosis with corneal reepithelization disorders.

作者： M.J.park O.M.Kwon ju H.park S.M.Lee E.J.Cha School of Electrical Engineering Chungbuk National University Department of Electrical Engineering Yeungnam University School of Electronic Engineering Daegu University Department of Biomedical Engineering School of MedicineChungbuk National University

This paper proposes new delay-dependent synchronization criteria for coupled Hopfield neural networks with time-varying delays. By construction of a suitable Lyapunov Krasovskii＇s functional and use of Finsler＇s lemma, novel synchronization criteria for the networks are established in terms of linear matrix inequalities （LMIs） which can be easily solved by various effective optimization algorithms. Two numerical examples are given to illustrate the effectiveness of the proposed methods.

We consider multi-agent systems with time-varying delays and switching interconnection topologies. By con- structing a suitable Lyapunov-Krasovskii functional and using the reciprocally convex approach, new delay-dependent consensus criteria for the systems are established in terms of linear matrix inequalities （LMIs）, which can be easily solved by using various effective optimization algorithms. Two numerical examples are given to illustrate the effectiveness of the proposed methods.

Enhancement of Au–Ag–Te contents in tellurium-bearing ore minerals via bioleaching

引用

International Journal of Minerals,Metallurgy and Materials 2018年第3期25卷 262-270页

作者： Nag-Choul Choi Kang Hee Cho Bong ju Kim Soonjae Lee Cheon Young park Department of Rural Systems Engineering Seoul National University Department of Earth and Environmental Sciences Korea University Department of Energy and Resource Engineering Chosun University

The purpose of this study was to enhance the content of valuable metals, such as Au, Ag, and Te, in tellurium-bearing minerals via bioleaching. The ore samples composed of invisible Au and Au paragenesis minerals(such as pyrite, chalcopyrite, sphalerite and galena) in combination with tellurium-bearing minerals(hessite, sylvanite and Tellurobismuthite) were studied. Indigenous microbes from mine drainage were isolated and identified as Acidithiobacillus ferrooxidans, which were used in bioleaching after adaption to copper. The effect of the microbial adaption on the bioleaching performance was then compared with the results produced by the non-adaptive process. The microbial adaption enhanced the Au–Ag–Te contents in biological leaching of tellurium-bearing ore minerals. This suggests that bioleaching with adapted microbes can be used both as a pretreatment and in the main recovery processes of valuable metals.
