The strong ferromagnetic nanoparticles are analyzed within the band structure-based shell model, accounting for discrete quantum levels of conducting electrons. As is demonstrated, such an approach allows description observed superparamagnetic features these nanocrystals. Assemblies superparamagnets incorporated into nonmagnetic insulators, semiconductors, or metallic substrates shown to displa...

This paper considers the problem of learning dynamic spatiotemporal fields using sensor measurements from a group of mobile sensing robots. We first introduce a general dynamical model for the spatiotemporal field. We then propose a family of motion strategies that can be used by a group of mobile robotic sensors to move along a uniformly observable periodic trajectory to collect point samples ...

Optical oxygen sensors were used to ascertain the level of oxygen consumed by individual salad leaves for optimised packaging of ready-to-eat (RTE) Italian salad mixes during refrigerated storage. Seven commonly found leaves in Italian salad mixes were individually assessed for oxygen utilisation in packs. Each leaf showed varying levels of respiration throughout storage. Using the information ...
