We consider 50GHz-spaced WDM transmission of 100Gbit/s PM-QPSK over a 2836km link. Theoretical performance on a "lumped" dispersion map is within 1dBQ of the optimal performance achievable with no dispersion compensation. © 2010 Optical Society of America. Source

Particulate filters are a key after-treatment component employed in all modern diesel engines. Key perfor-mance criteria of particulate filters are pressure drop and filtration performance. Both are determined by geometric design parameters such as size, cell density and wall thickness, as well as intrinsic wall scale material properties. The latter are usually related to the properties of the pore space such as porosity, pore size and pore morphology. In this paper tools to simulate the motion and deposition of discrete diesel soot particles through and on a finite section of a porous filter wall are discussed. The tools and models developed are solved for the com-plex flow through the pore space, either using the commercial software (FLUENT) or an internally developed Lattice-Boltzmann solver. The flow is combined with an internally developed discrete particle dynamics tracking routine to advance the particle motions in time. In the model the flow field is continually updated, taking account of the accumulation of soot. The simulated effect of mean pore size and porosity are dis-cussed for examples of synthetic microstructures. A comparison with experimental data shows good agree-ment for clean permeability. Source

We use the analytical Gaussian noise model to assess the achievable capacity over a fully transparent network with 18 nodes and 26 physical connections. By applying a network-centric approach, we show that the use of adaptive modulation in combination with ultralow loss fiber can provide an increase in the achievable capacity. The use of ultralow loss, large effective area fibers can allow for further capacity increase. © 2015 Optical Society of America. Source

The concept of process intensification has been around for at least a decade in chemical process engineering. Conventional "batch" synthesis, with mixing and reactions done in bulky meter-scale vessels, often generates by-products and suffers from energy and material waste. Also, safety could become a concern when high-energy processes or highly toxic reagents are involved. As one of its key aspects, process intensification considers development of new equipment allowing substantially smaller, cleaner, safer and more energy-efficient and scalable methods for industrial-scale production of pharmaceutical and specialty chemical products. These needs can be addressed through the continuous-flow technology of Corning's Advanced-Flow™ glass reactors, which consist of modules with millimeter-scale channels that allow optimization of thermal and interfacial mass transfer for reducing overall heat and mass transfer resistances. This paper will describe Corning® Advanced-Flow™ reactor technology and several application cases in which these reactors demonstrated their high potential for industrial deployment and process intensification due to their ability to increase the efficiency, scalability, and quality of chemical processing - all while reducing environmental impact, performance variability and cost. © 2012 WIT Press.

We study four different measurement methods of multi-path interference (MPI) in quasi-single-mode (QSM) fibers and compare their consistency and accuracy. Three methods agree to within 1.7 dB in each case while one overestimates MPI. © 2015 IEEE. Source
