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 ...
Over the past few years, genes involved in the ontogenesis of tetrapod limbs have been isolated and characterized. Some of the developmental mechanisms responsible for the morphogenesis of these complex structures can now be investigated through a new appr ...
The formulation and implementation of wavelet based methods for the solution of multi-dimensional partial differential equations in complex geometries is discussed. Utilizing the close connection between Daubechies wavelets and finite difference methods on ...
This paper presents a computational analysis on forced vibration fluid-structure interaction in compressible flow regimes. A so-called staggered approach is pursued where the fluid and structure are integrated in time by distinct solvers. Their interaction ...
Due to their nature, distributed systems are vulnerable to failures of some of their parts. Conversely, distribution also provides a way to increase the fault tolerance of the overall system. However, achieving fault tolerance is not a simple problem and r ...
The authors describe a strategy for the synthesis of 'nanocrystal mols.', in which discrete nos. of Au nanocrystals are organized into spatially defined structures based on Watson-Crick base-pairing interactions. The authors attach single-stranded DNA olig ...
The solidification of eutectic alloys has been described by means of stochastic methods. These methods allow some of the hypotheses which are usually made in deterministic models to be relaxed, in particular those related to the description of grain imping ...
Previous studies of cyanide exchange on square planar tetracyanoplatinate complex [Pt(CN)4]2- have been undertaken only at a high pH. For a more complete fundamental understanding of this system we extended the investigations of these exchanges over a larg ...
A multicriteria decision support system has been developed to evaluate alternatives for sustainable and integrated energy centres for rural development in the Mediterranean area. The search for the most suitable solution for a fixed site is a complex probl ...
The field pattern of the resonator used in a quasi-optical gyrotron operating in the millimetre wave range is measured. Two resonators are studied: one composed of a spherical mirror and an ellipsoidal grating and the other symmetric using two mirrors with ...
