A novel design of molecular buffer for molecule storage and delivery using a PANDA ring resonator is proposed. The optical vortices can be generated and controlled to form the trapping tools in the same way as the optical tweezers. In theory, the trapping force is formed by the combination between the gradient field and scattering photons, which is reviewed. By using the intense optical vortices generated within the PANDA ring resonator, the required molecules can be trapped and moved (transported) dynamically within the wavelength router or network, ie, a molecular buffer. This can be performed within the wavelength router before reaching the required destination. The advantage of the proposed system is that a transmitter and receiver can be formed within the same system, which is available for molecule storage and transportation. Source

With the fast development in ad hoc wireless communications and vehicular technology, it is foreseeable that, in the near future, traffic information will be collected and disseminated in real-time by mobile sensors instead of fixed sensors used in the current infrastructure-based traffic information systems. A distributed network of vehicles such as a vehicular ad hoc network (VANET) can easily turn into an infrastructure-less self-organizing traffic information system, where any vehicle can participate in collecting and reporting useful traffic information such as section travel time, flow rate, and density. Disseminating traffic information relies on broadcasting protocols. Recently, there have been a significant number of broadcasting protocols for VANETs reported in the literature. In this paper, we classify and provide an in-depth review of these protocols. © 2012 IEEE. Source


The internally heat-integrated distillation column (HIDiC) is a complex column configuration which is more energy efficient than the equivalent conventional column or the distillation column with direct vapor recompression scheme (VRC). Exploiting the heat integration between two diabatic sections operating at different pressures of the HIDiC can greatly enhance the energy performance of the system. On the other hand, the design and optimization of HIDiC is more difficult than those of the conventional distillation column or the column with VRC. The former involves many design parameters, and the most critical one is the pressure ratio between both diabatic sections. However, the heat distribution along the diabatic sections is also another significant factor not yet thoroughly investigated. In this work, two typical distribution schemes, i.e. uniform heat transfer area and uniform heat distribution, are studied by applying a novel approach to solve the simulation problem in Aspen Plus 2004.1. The comparison of both distributing schemes is discussed via two widely-used case studies, namely benzene-toluene separation and propylene-propane splitter. © 2009 Elsevier Ltd. All rights reserved.

The internally heat-integrated distillation column (HIDiC) is an interesting separation alternative to the conventional column or the vapor recompression distillation (VRC). In an HIDiC, the influence of heat distribution along the column section has a significant impact on the design and optimization in addition to the compressor pressure ratio. In this work, the optimization of heat distribution in the HIDiC is completely investigated through the application of flowsheet modeling and optimization solver in Aspen Plus. A commercial-scale propylene/propane splitter is used as a case study to illustrate the effect of heat distribution on energy or cost performance. A comparison of the optimum HIDiC structures obtained from different objective functions is discussed. Some optimum HIDiC structures could be evolved into Linde double columns with a side rectifier, which is a common application found in air separation process. This structure is potentially another interesting alternative to the conventional VRC. © 2011 Elsevier Ltd. Source


The green microalga strain, Botryococcus braunii KMITL 2, was isolated from a freshwater reservoir in central Thailand, and the effects of light, nitrogen, phosphorus, iron, cultivation time and salinity on lipid production were studied by varying parameters one at a time. When cultured in Chlorella medium containing 222mgL -1 phosphorus (PO43--P) under continuous illumination of 200μEm -2s -1 with a salinity of 0psu, a maximum lipid content of 54.69±3.13% was obtained. Its high lipid content makes strain KMITL 2 a potential source for biodiesel production in tropical regions. © 2011 Elsevier Ltd. Source
