Mathematical modeling tools are extensively used in Geosciences to delineate the earth structure at various spatial scales as well as to simulate coupled earth processes involving multiphysics concepts. COMSOL, a Multiphysics finite element method based numerical modeling package, can be used to analyze complex systems like earth where various physical parameters are involved and interlinked. ...
This paper covers the following: * All-Optical Light Modulation of surface plasmon polaritons (SPPs) is achieved using asymmetric single nanoslits. A high on/off switching ratio of >20 dB and phase variation of >? were observed with the device lateral dimension of only about 2 ?m. * Efficient unidirectional excitation of SPP as well as beam splitting are achieved using the dielectric–film ...
Tim Poole graduated from Cambridge University with a Masters degree in Engineering in 2008 and immediately joined JDR Cables Systems, a leading supplier of custom subsea oil and gas umbilical systems and renewable energy cables. He started in the Research and Development team, working on creating new products lines and testing umbilicals, which included fatigue, tensile and bend stiffness ...

A three phase transformer with very low harmonic pollution transferred back to power line is here presented. In fact, thanks to the described setup, intermediate harmonics (5th and 7th) are not going out back to the power line feeding the primary. These results has been extensively validated versus measurements performed on produced and shipped machine. With these results, TMC is then featuring ...

Calibration of field instruments used in radiation treatment clinics is currently traceable to NIST primary standards via protocols involving static, flat-field radiation beams. By contrast, radiation beams prescribed for treating cancer incorporate temporal and spatial modulation strategies in order to maximize dose to the tumor while sparing healthy tissue. Differences in the detector ...

The model can be utilized for a virtual design of a hybrid joint interms of corrosion prevention. Structures can be optimized by the simulations by tailoring the parameters to get the most suitable result towards a Computer-Aided Engineering CAE regarding corrosion protection. This kind of computer based studies is a very useful method to accelerate developments in light weight structural design ...

Capacitive deionization (CDI) is a desalination technology which is based on the storage of ions in the electrical double layer of a pair of oppositely polarized porous carbon electrodes, which are usually assembled using activated carbon particles (Figure 1). It is efficiently deployed for desalinating water with moderate salt content (eg in domestic water softening). To broaden its ...

Internal combustion engine components have been a main research interest over many decades. The structural mechanics and dynamics of the piston rings has been a large focus of work in order to gain a greater understanding of the how the piston ring dynamics affect the piston ring. Piston rings are often coated to reduce the level of wear on the ring as they will suffer substantial levels of ...

We present an optimization procedure to improve the propagation properties of the depressed-cladding, buried micro-structured waveguides formed in a z-cut lithium niobate (LN) crystal by high repetition rate femtosecond (fs) laser writing. It is shown that the propagation wavelength for which the confinement losses of ordinary (O) and extraordinary ordinary (E) polarizations are below 1 dB/cm ...

The use of piezoelectric materials in hearing aid loudspeakers, also called receivers, presents technical and economic advantages such as reducing the number of parts of the system and its manufacturing cost. However, the performance of such systems is still not competitive when compared to traditional electrodynamic loudspeakers. In order to achieve an appropriate performance, one option is to ...
