Forward-viewing CMUT arrays for medical Imaging
(IEEE-INST Electrical Electronics Engineers Inc, 2004-07)
This paper reports the design and testing of forward-viewing annular arrays fabricated using capacitive micromachined ultrasonic transducer (CMUT) technology. Recent research studies have shown that CMUTs have broad frequency ...
A parametric approach to construct two-variable positive real impedance functions for the real frequency design of mixed lumped-distributed matching networks
(IEEE, 2004)
In this paper, a parametric approach to construct two-variable positive real driving point impedance functions characterizing lossless ladder networks with mixed lumped and distributed elements is presented. The proposed ...
Tip singularity of the electromagnetic field at the apex of a material cone
(Springer-Verlag Berlin, 2004)
The tip Singularity of the electromagnetic field at the apex of a cone is investigated in its most general framework. To this end one considers, without loss of generality, a circularly symmetric cone which separates two ...
Influence of the velocity on the energy patterns of moving scatterers
(Taylor & Francis, 2004)
Parallel to the developments in the communication through space vehicles achieved during the last two decades, the scattering problems connected with moving objects became more and more important from both theoretical and ...
A computer-aided design technique for lossless matching networks with mixed, lumped and distributed elements
(Elsevier GMBH, 2004)
A computer-aided method for the design of lossless broadband matching networks with lumped elements and commensurate transmission lines is presented. ne method is based on combining the simplifield real frequency technique ...
Range sensing with a Scheimpflug camera and a CMOS sensor/processor chip
(IEEE-INST Electrical Electronics Engineers Inc, 2004-02)
An image-based range-sensing technique is presented. The technique is originally considered for highway collision avoidance applications, but its generality makes it suitable for application in robotics, manufacturing, and ...
Immitance data modelling via linear interpolation techniques: a classical circuit theory approach
(Wiley-Blackwell, 2004-11)
With the advancement of the manufacturing technologies to produce new generation analog/digital communication systems, immitance data modelling has gained renewed importance in the literature. Specifically, models are ...
Adaptive Kalman receiver for OFDM systems with transmit diversity in mobile wireless channels
(Walter De Gruyter GMBH, 2004-12)
A new joint channel tracking and symbol detection scheme is proposed in this paper for pilot symbol assisted transmit diversity OFDM systems by exploiting the correlation of the adjacent subchannels. Modelling the channel ...
A novel representation method for electromyogram (EMG) signal with predefined signature and envelope functional bank
(IEEE, 2004)
In this paper, a new method to model EMG signals by means of "Predefined Signature and Envelope Functional Banks (PSEB)" is presented. Since EMG signals present quasi-stationary behavior, any EMG signal Xi is modeled by ...
The general equation of motion via the special theory of relativity and quantum mechanics
(2004)
Herein we present a whole new approach to the derivation of the Newton's Equation of Motion. This, with the implementation of a metric imposed by quantum mechanics, leads to the findings brought up within the frame of the ...
