We propose the concept of nonreciprocal filtering power dividers, which are compact devices able to merge functionalities dividers and combiners, selectivity bandpass filters, magnetless nonreciprocity from time-modulation. A prototype this type operating at microwaves has been implemented in microstrip technology. The device is composed a Wilkinson divider integrated with two identical filters...

INSAR(Interferometric Synthetic Aperture Radar) has been studied and used widely in the field of generating high accuracy DEM(Digital Elevation Model). The processing of INSAR includes many key technologies, such as image matching, phase unwrapping, baseline estimation, etc. The phase unwrapping is difficult, but it can be made easy and simple by an excellent interferogram filtering, as is ofte...

extended kalman filtering (ekf) is a nonlinear dynamic data reconciliation (nddr) method. one of its main advantages is its suitability for on-line applications. this paper presents an on-line nddr method using ekf. it is implemented for two case studies, temperature measurements of a distillation column and concentration measurements of a cstr. in each time step, random numbers with zero mean ...

there have been several efforts in the literature to extract as much information as possible from the financial networks. most of the research has been concerned about the hierarchical structures, clustering, topology and also the behavior of the market network; but not a notable work on the network filtration exists. this paper proposes a stock market filtering model using the correlation - ba...

this paper presents an innovative active power filter design method to simultaneously compensate the current harmonics and reactive power of a nonlinear load. the power filter integrates a passive power filter which is a rl low-pass filter placed in series with the load, and an active power filter which comprises an rl in series with an igbt based voltage source converter. the filter is assumed...

Rule-based information filtering systems maintain user profiles where the profile consists of a set of filtering rules expressing the user’s information filtering policy. Filtering rules may refer to various attributes of the data items subject to the filtering process. In personal rulebased filtering systems, each user has his/her own personal filtering rules. In stereotype rule-based filterin...

filtering of web pages with inappropriate contents is one of the major issues in the field of intelligent network's security. having a good intelligent filtering method with high accuracy and speed is needed for any country in order to control users' access to the web. so, it has been considered by many researchers. presenting web pages in an understandable way by machines is one of the most im...
