Improving magnetic nanothermometry accuracy through mixing-frequency excitation

Improving Accuracy Through Selective Doubly Compensated Summation

With systems such as Road Runner, there is an early trend in super computing to offload parallel tasks to special purpose co-processors, composed of many relatively simple scalar processors. The cheaper commodity class equivalent of such a processor would be the graphics card, potentially offering super computer power within the confines of a desktop PC. Graphics cards however are not without p...

Broadband vibration-based energy harvesting improvement through frequency up-conversion by magnetic excitation

Traditional vibration-based energy harvesters are designed for a specific base excitation frequency by matching its fundamental natural frequency. This work presents the modeling and analysis of a nonlinear, magnetically excited energy harvester that exhibits efficient broadband, frequency-independent performance utilizing a passive auxiliary structure that remains stationary relative to the ba...

Polymer-C60 excitation mixing

The one-electron spectrum of C60 cluster which is coupled to PPV chain is calculated. It shows that non-rigid band scheme has to be considered for this composite system. The splitting of states in the closest valence and conduction bands is discussed. Ó 1999 Elsevier Science B.V. All rights reserved. PACS: 36.20-r; 36.20.Kd; 36.40.+d

Improving accuracy of information extraction from quantitative magnetic resonance imaging

Improving the Reconstruction Accuracy of Inversion Strategies through Energetic Constraints

Microwave imaging techniques are widely investigated in many applied sciences such as the subsurface prospecting [1] and the medical diagnosis [2]. Unfortunately, when inverse scattering approaches are considered, the drawbacks of non-linearity and ill-posedness [3] have unavoidably to be dealt with. Therefore, the problem at hand is usually recast as the minimization of a suitable cost functio...
