This paper reports and fully characterizes a coulometric nanotitrator and its application for four different types of titrations: precipitation, complex-formation, redox and acid-base nanotitrations. This simple device, composed of Pt or Ag planar electrod ...
We investigate the well-posedness of a phase-field model for the isothermal solidification of a binary alloy due to Warren-Boettinger [12]. Existence of weak solution as well as regularity and uniqueness results are established under Lipschitz and boundedn ...
Linear systems of equations with structured coefficient matrices arise in several applications in signal processing and communications. In this paper we develop fast algorithms for updating the solutions of such systems when the coefficient matrices underg ...
The Wold decomposition of discrete-time CS (cyclostationary) processes into regular and predictable component is considered. Using the properties of the zeros of linear periodic systems it is shown that the predictable component consists of a linear combin ...
Reasons for the continuing difficulty in making definitive measurements of pulse wave attenuation in elastic tubes and arteries in the presence of reflections are sought. The measurement techniques available were re-examined in elastic tubes mimicking the ...
We propose a numerical method for the solution of the Quasi3D hydrodynamic equations. This approach uses a combination of standard linear finite elements along the vertical direction and non-conforming Raviart-Thomas elements in the horizontal planes. We d ...
Traction tests were performed on the bovine anterior cruciate ligament-bone complex at seven strain rates (0.1, 1, 5, 10, 20, 30, 40%/s). Corresponding stress-strain curves showed that, for a given strain level, the stress increased with the augmentation o ...
The classic Preisach model is used to describe a general hysteretic behaviour, and as most nonlinear systems, its output contains higher harmonics. A Fourier analysis of a specific class of weighting functions for the Preisach model relates some free param ...
The Wold decomposition of discrete-time CS (cyclostationary) processes into regular and predictable component is considered. Using the properties of the zeros of linear periodic systems it is shown that the predictable component consists of a linear combin ...
The dielectric response of the relaxer ferroelectric PbMg1/3Nb2/3O3 (PMN) is found to be a non-analytical function of the ac field, with the absolute value of the non-linear component of the polarization given by \P-nl\ alpha E-m(gamma(omega,T)). The depen ...
