A new method for computing the component values of LC ladder equalizers for broadband matching purposes is presented. The method is inspired by the theory of recursive identification and results in a very compact algorithm. As in the usual real frequency t ...
Light propagation in two-layered turbid media having an infinitely thick second layer is investigated in the steady-state, frequency, and time domains. A solution of the diffusion approximation to the transport equation is derived by employing the extrapol ...
We stufy inhomogeneous transmission lines for which the product of the series impedance and the shunt admittance is a constant. In these devices, we can show that the dynamics of the voltage and current is described by a supersymmetric Hamiltonian. The for ...
We study the fairness of TCP Vegas. The latter is an alternative to the commonly used TCP Reno, and uses measures of the round trip time as feedback on congestion. We consider two cases that depend on the value of the two parameters α and β co ...
BACKGROUND AND OBJECTIVE: Photodynamic therapy (PDT) is an efficient technique to treat superficial early cancers in the pharynx, esophagus, and tracheo-bronchial tree. However, the lack of selectivity of some of the clinically used photosensitizers can re ...
Single mode guided optics have recently taken a predominant place in communications systems. For instance single mode fibres enable long span, high data rate transmission links to be installed. In such fibers the data rate is ultimately limited by the chro ...
The analysis of reactive systems requires models representing the system, its interaction with the environment, and taking into account features of the underlying execution structure. It is important that such models are timed if analysis concerns performa ...
Considerable efforts are presently being made in the fabrication of miniaturized optical devices. An automated assembly technique for small optical components based on standardized holders and on-line alignment of the optical elements has been developed. T ...
