Synthesis of arbitrary current mode filter by LI Zhi-jun1, WANG Chun-hua2, LIU Rong1

“…A new general analytical synthesis method for arbitrary current mode filter was presented.The method was based on the analytical decomposition of a complicated high-order transfer function into n lossless integrators and n cur-rent proportional blocks by a succession of innovative algebra process.The filter structure based on MCCIIs was pro-posed with the following advantages: 1) it can be used not only for arbitrary-order filters,but also for different filter types such as Butterworth,Chebyshev and Elliptic;2) the circuit structure proposed only contains（2n+1） active elements,（2n+1） resistors and n capacitors;3) all the elements are grounded,so it is convenient to be integrated;4) the different filter functions such as high-pass,low-pass,band-pass,band-reject and all-pass can be obtained when it act as a Butter-worth filter.A third-order elliptic low-pass filter and a sixth-order Butterworth universal filter were employed to demon-strate the realization scheme.The validity of the proposed structure was verified through PSPICE simulations.…”

Outlier Detection Method of Dam Monitoring Data Based on Robust Estimation and Variable Separation by LIANG Huibin, ZHANG Han, ZHANG Linsong, CAO Yuxin, ZHOU Jingren

“…The original monitoring data of dams is the most important data to grasp the operation behavior of the dams,and the outliers in the data are the focus during the analysis.Outliers are divided into two categories.One category is caused by measurement errors and should be eliminated or supplemented to avoid affecting subsequent analysis.The other is caused by structural mutations and should be highly valued.At present,main outlier recognition methods in dam engineering are based on traditional mathematical statistics and do not consider the influence of structural anomalies,which results in low recognition accuracy.Therefore,based on an in-depth study of dam monitoring data and outlier characteristics,this paper first employs robust MM estimation to eliminate the normal influence of internal and external factors and then adopts the residual measured value to eliminate the stable abnormal influence by difference before and after.Finally,according to the minimum value method,outlier identification is conducted on the residual values.The application of the measured dam data proves that the proposed method can identify the measurement outliers more effectively and robustly,and avoid the interference of structural stability anomalies.…”

Cartographie sémantique par zonage à dires d’acteurs : Le Ferlo (Sénégal) et l’observatoire de Tessekere by Mehdi Saqalli, Amadou Hamath Diallo, Doryan Kaced, Mahamadou Belem, Raoul Iopue, Yayé Moussa, Axel Ducourneau, Benoît Gaudou

“…By GIS-merging together all the maps obtained, each corresponding to an interview, we obtain a spatialized database on the determinants structuring this territory. Although the structural, ecological and socio-historical elements remain and even tend towards the specialization of territories into production 'countries', the short 2-months period herds graze in the Ferlo and the generalized use of supplementation during the pastoral lean season suggests a reorientation of these herds towards the south. …”
