In a first-order topological phase with sublattice degrees of freedom, change in the boundary termination has no effect on existence gapless states dimensions higher than one. However, such may strongly affect physical properties those states. Motivated by this observation, we perform systematic study impact terminations physics two-dimensional kagome lattice. We find that energies Dirac points...

We propose two perturbation-based extremum seeking control (ESC) schemes for general single input output nonlinear dynamical systems, having structures similar to that of the classical ESC scheme. novel adaptation laws excitation signal amplitudes in each scheme drive zero. The rates decay both are governed by gradient measures unknown reference-to-output equilibrium map show proposed achieve p...

in this paper, by considering a squint angle for synthetic aperture radar in the strip-map mode, a method is proposed for estimating parameters of a fixed acceleration moving target. non-zero doppler centroid and range-azimuth coupling in the squint mode add complexity to estimation equations of moving target parameters and cause doppler ambiguity. this, in turn, causes to lose the efficiency o...

In this paper, we propose a proof scheme of shuffle, which is an honest verifier zero-knowledge proof of knowledge such as the protocols by Groth and Furukawa. Unlike the previous schemes proposed by Furukawa-Sako, Groth, and Furukawa, our scheme can be used as the shuffle of the elements encrypted by Paillier’s encryption scheme, which has an additive homomorphic property in the message part. ...

Audio classification serves as the fundamental step towards the rapid growth in audio data volume. Automatic audio classification is very useful in audio indexing; content based audio retrieval and online audio distribution. The accuracy of the classification relies on the strength of the features and classification scheme. In this work both, time domain and frequency domain features are extrac...

The discovery that natural and synthetic chemicals, in the form of excreted hormones and pharmaceuticals, as well as a vast array of compounds with domestic and industrial applications, can enter the environment via wastewater treatment plants and cause a wide variety of environmental and health problems even at very low concentrations, suggests the need for improvement of water recycling. Thre...

Accurate knowledge extracted from relevant datasets is essential for making reasonable and timely decisions using data mining algorithms. In order to both guarantee data quality collected and prevent disclosure of confidential or sensitive information, privacy preservation has become a major concern in the design of practical data mining applications. In this paper, a novel data distortion appr...

Points of zero charge were determined on two highly weathered surface soils from Puerto Rico, an Oxisol and Ultisol, as well as mineral-standard kaolinite and synthetic goethite using three methods: (1) potentiometric titration measuring the adsorption of H and OH� on amphoteric surfaces in solutions of varying ionic strength (I) (point of zero salt effect), (2) direct assessment of surface cha...
