FPGA Implementation of Embedded Fuzzy Controllers for Robotic Applications
(Institute of Electrical and Electronics Engineers, 2007)
Fuzzy-logic-based inference techniques provide efficient solutions for control problems in classical and emerging applications. However, the lack of specific design tools and systematic approaches for hardware implementation ...

Application of total least squares to the derivation of closed-form green's functions for planar layered media
(Institute of Electrical and Electronics Engineers, 2007)
A new technique is presented for the numerical derivation of closed-form expressions of spatial-domain Green's functions for multilayered media. In the new technique, the spectral-domain Green's functions are approximated ...

Design of compact low-pass elliptic filters using double-sided MIC technology
(Institute of Electrical and Electronics Engineers, 2007)
A novel implementation of stepped-impedance low-pass elliptic filters is presented in this paper. The filters are based on the well-known technique of cascading high- and low-impedance sections to simulate the ladder LC ...

Types of gas fluidization of cohesive granular materials
(American Physical Society, 2007)
Some years ago it was shown that gas-fluidized powders may transit from solidlike to fluidlike fluidization prior to bubbling, shedding light on a long-standing controversy on the nature of “homogeneous” fluidization. In ...

Enhanced backward wave propagation in evanescent waveguides loaded with split ring resonators
(AIP Publishing, 2007)
This paper reports on the design and experimental characterization of evanescent waveguides loaded with split ring resonators SRRs supporting enhanced backward wave propagation. With respect to previous negative refractive ...

A design tool for high-resolution high-frequency cascade continuous- time Σ∆ modulators
(SPIE, 2007)
This paper introduces a CAD methodology to assist the de signer in the implementation of continuous-time (CT) cas- cade Σ∆ modulators. The salient features of this methodology ar e: (a) flexible behavioral modeling ...

Towards a systematic design of isotropic bulk magnetic metamaterials using the cubic point groups of symmetry
(American Physical Society, 2007)
In this paper, a systematic approach to the design of bulk isotropic magnetic metamaterials is presented. The roles of the symmetries of both the constitutive element and the lattice are analyzed. For this purpose, it is ...

Design of wide-band semi-lumped bandpass filters using open split ring resonators
(Institute of Electrical and Electronics Engineers, 2007)
Open split ring resonators (OSRRs) are used in this letter to design wide-band semi-lumped bandpass filters. OSRRs work as lumped LC series elements due to their small electrical size and can be then used as building blocks ...
