Existing multi-dimensional sequential pattern mining methods only discover multi-dimensional sequential pattern in databases involving one sequential dimension. Since multi-dimensional sequential patterns may exist in databases containing more than one sequential dimension, in this paper, we present algorithm PSeq-MIDim for mining multi-dimensional sequential patterns from multiple sequential d...

A new mathematical formulation for the Cardiff nonlinear behavioral model is presented in this work which includes dc bias voltages (drain and gate) into model. It has been verified by modeling a GaN on SiC high electron mobility transistor (HEMT) at 3.5 GHz. For case presented, interpolation of load–pull data resulted more than 90% reduction density required to generate over wide range points.

Based on the concept of “economic cycle cube”, this research constructs the multi-dimension monitoring system for Xinjiang Autonomous Region. The system is able to monitor the main subjects of Xinjiang regional economy including economic growth, investment, consumption, trade, prices, industrial enterprises, coal industry and services, with the tools like diffusion index, composite index, signa...

This paper deals with the estimation of range-Doppler plane in pulse Doppler radar system, accounting both for clutter-free scenario and clutter scenario. A modified adaptive multi-pulse compression (MAMPC) algorithm including the estimation stages of range dimension and Doppler dimension is proposed for clutter-free scenario, where each stage is implemented based on the gain constraint adaptiv...

We describe a formulation of multi-reference perturbation theory that obtains a rigorous upper bound to the second order energy by minimizing the Hylleraas functional in the space of matrix product states (MPS). The first order wavefunctions so obtained can also be used to compute the third order energy with little overhead. Our formulation has several advantages including (i) flexibility with ...
