An algorithm for combining results of different clusterings is presented in this paper, the objective of which is to find groups of patterns which are common to all clusterings. The idea of the proposed combination is to group those samples which are in the same cluster in most cases. We formulate the combination as the resolution of a linear set of equations with binary constraints. The advantage...
Spectral characteristics of fundamental magnetic oscillation in the circular waveguide-based resonator with dielectric and metal-dielectric heterogeneities have been investigated.
In this paper, the Bragg mirrors manufactured of the macroporous silicon infiltrated with liquid crystals are investigated. The reflectance spectrum of the structure is calculated using a transfer matrix method. The influence of the applied alternating field on reflectance spectrum of the structure is considered. The comparative analysis of the Bragg lattices reflectance spectra with different anisotropy...
The thermal dependence of mirror reflective properties in oxide-confined VCSEL is investigated. The temperature distribution over the cavity versus applied current is calculated. The refractive indexes of the mirror layers are redefined by using the temperature coefficients, and changes in radial reflectance spectra of the mirror are analyzed. Results show a shift of stopband DBR at different injection...
This paper presents a novel application of in-situ dynamic reconfiguration to a multi-channel complex code matched filter. The filter forms the first stage of a UMTS basestation's searcher partition. New configuration data is generated on-chip and loaded into the active circuitry in parallel to operation using the Xilinx Virtex families SRL16 functionality. Data-folding (Foulk, 1993) produces reconfiguration...
The development of a real-time advanced dynamic robot arm controller which is cost-effective, compact and flexible is described for a six joint arm. It utilizes IBM PC-AT as a host computer and was configurated with up to seven digital signal processors. First, the controller interprets high-level control commands from the IBM PC-AT and performs a robot arm control computation based on the Newton-Euler...
