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 ...
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 ...
Fluctuation theory of the liquid-glass transition
(Trans Tech Publications Ltd, 2004)
The glassy state and the character of the liquid-glass transition from undercooled liquid to amorphous solid is one of the biggest challenges of our time. In spite of significant progress we still cannot explain accurately ...
Theoretical calculation of the kinetic coefficient of normal crystal growth
(Trans Tech Publications Ltd, 2004)
An expression for the velocity u of migration of a diffuse simple crystal-melt interface has been derived on the basis of the theory of atomic mobility in supercooled liquids: u = K-0 (T / T-m) DeltaT, where DeltaT = T-m ...
Breakdown of the Stokes-Einstein relation in supercooled liquids
(Trans Tech Publications Ltd, 2004)
Breakdown of the Einstein-Stokes relation in undercooled liquids is one of the unsolved problems in the theory of liquids. The self-diffusion coefficient follows the temperature dependence of the Einstein-Stokes equation ...
Integrated ultrasonic imaging systems based on CMUT arrays: Recent progress
(IEEE, 2004)
This paper describes the development of an ultrasonic imaging system based on a two-dimensional capacitive micromachined ultrasonic transducer (CMUT) array. The transducer array and front-end electronics are designed to ...
A new software tool to model measured RF-data with optimum circuit topology
(IEEE, 2004)
In this paper a new S/W tool is presented to model measured RF data employing immitance interpolation techniques. This S/W tool also employs a recently developed sub-routine, which generates circuit models with least number ...
Üç boyutlu akustik görüntüleme için ön alıcı-verici tümdevre
(IEEE, 2004)
Tıbbi ultrasonik görüntüleme sistemleri, genel olarak bir çevirici elemanı ve akustik işaretin üretilip algılanmasından sorumlu elektronik oluşmaktadır. Tek boyutlu dönüştürücü dizileriyle, incelenmekte olan ortamın iki ...
3-B nesne bilgilerinin vektor nicemleme yöntemleri ile sıkıştırılması
(IEEE, 2004-10-25)
Bu çalışmanın amacı, bağlanırlık kodlaması için gerçeklenmiş [I]'deki algoritmayı bazı yenilikler ile uygulamak ve koordinat sıkıştırması için 3-B (3 Boyutlu) nesne gösterimleri alanında kullanımı kısıtlı olan kayıplı bir ...
Pilot-aided bayesian MMSE channel estimation for OFDM systems: Algorithm and performance analysis
(IEEE, 2004)
This paper proposes a computationally efficient, pilot-aided minimum mean square error (MMSE) channel estimation algorithm for OFDM systems. The proposed approach employs a convenient representation of the discrete multipath ...
