Evolutionary neuro-space mapping technique for modeling of nonlinear microwave devices
This paper presents a new advance in Neuro-space mapping (Neuro-SM) techniques for modeling nonlinear microwave devices. Suppose that existing device models (namely, coarse models) cannot match the behavior of a new device (referred to as the fine model). By neural network mapping of the voltage and current signals from the coarse to the fine model...
Providing resiliency for optical grids by exploiting relocation: a dimensioning study based on ILP
Solubility in CO(2) and carbonation studies of epoxidized fatty acid diesters: towards novel precursors for polyurethane...
Novel linear polyurethanes were synthesized by bulk polyaddition of diamines with two vegetable-based biscarbonates produced from oleic acid methyl ester. Internal carbonated fatty acid diester (ICFAD) and terminal carbonated fatty acid diester (TCFAD) were obtained by the reaction of their epoxide precursors with CO(2). Terminal epoxy fatty acid d...
The structure of the EU mediasphere.
Published in PloS one
A trend towards automation of scientific research has recently resulted in what has been termed "data-driven inquiry" in various disciplines, including physics and biology. The automation of many tasks has been identified as a possible future also for the humanities and the social sciences, particularly in those disciplines concerned with the analy...
Spectral Efficient Cooperative Diversity Technique with Multi-Layered Modulation
This paper proposes a spectral efficient cooperative diversity technique with multi-layered modulation for high data rate transmissions. The proposed system transmits with different cyclic delay and phase rotation patterns, in order to achieve cooperative diversity gain for all transmit signals from the source. Since these patterns increase the int...
Sleepless in Seoul: ‘The Ant and the Metrohopper’
One of Aesop's (La Fontain's) famous fables 'The Ant and the Grasshopper' is widely known to give a moral lesson through comparison between the hard working ant and the party-loving grasshopper. Here we show a slightly different version of this fable, namely, "The Ant and the Metrohopper", which describes human mobility patterns in modern urban lif...
Content Protective Multi-Agent Platform for MsMu Service and Pattern-Based Content Management
Recent research on mobile Internet protocol television and digital right management (DRM) interconnections has focused on multimedia technologies designed to enhance content scalability and adaptive content distribution. However, due to the architectural and scalable limitations, recent systems are not flexible and securable with respect to their a...
Hierarchical Structure in Polymer-Based Drug Delivery Systems as Probed by Calorimetric Measurements
Thermoporosimetry (TPM), a differential scanning calorimetry technique that relies on the shift of transition temperatures caused by the confinement of liquids, was applied to elucidate the complex morphology of drug-loaded polymeric microcapsules prepared by the emulsion solvent evaporation method. For the very first time, TPM has been applied sim...
