Magnetic nanoparticle systems can be divided into single-core nanoparticles (with only one magnetic core per particle) and magnetic multi-core nanoparticles (with several magnetic cores per particle). Here, we report multi-core nanoparticle synthesis based on a controlled precipitation process within a well-defined oil in water emulsion to trap the superparamagnetic iron oxide nanoparticles (SP...

Previous density functional theory (DFT) studies of the 1/3 h1 210i screw dislocation in titanium have shown metastable core structures depending on the initial position of the dislocation line. We investigate this problem by modeling a screw dislocation with two initial positions using both DFT and a modified embedded atom (MEAM) potential for Ti with flexible boundary conditions. Both DFT and...

A new integrated magnetic full wave dc/dc converter1 that provides flexible transformer design by incorporating an independent output inductor winding is introduced. The transformer is implemented on a traditional three-leg magnetic core. The inductor winding can be separately designed to control the output current ripple. The cross-sectional area of the inductor core leg can be reduced dramati...

This paper presents the Gaspar data-centric framework to develop high performance parallel applications in Java based on a map pattern of computation. The framework provides an efficient data Application Programming Interface(API) that supports data tiling and flexible data layout. Data tiling and layout control enables the improvement of data locality, which is essential to foster application ...

Extensible client-server software requires a clear separation of core services from those that are customizable. This separation is difficult, as these customizable features tend to crosscut the primary functionality of the core services. We believe that an aspect-oriented approach to client-server architectures supports extensibility in a way that is more flexible than traditional approaches. ...

We present a Monte Carlo simulation study of the phase behaviour and molecular organizations observed in a system of nanoparticles constituted by a central spherical core with attached mesogenic groups, which we model with a set of suitable Gay-Berne units connected by flexible spacers. We show that the choice of radial or tangential orientation of the attached mesogenic groups with respect to ...

Even today, some types of fuel cells have been already used in practical applications such as combined heat and power generation applications and space vehicle applications. Though research and development activities are still required, the fuel cell technology is one of the most important technologies that allow us to draw the environment friendly society in the twenty-first century. This sect...
