- To study air distribution in commercial aircraft cabins so as to analyze their indoor air quality and thermal comfort, Computational Fluid Dynamics (CFD) has been frequently used. This study obtained a detailed geometric model by a laser tracking system with reverse engineering for the first-class section of an MD-82 aircraft cabin. By performing CFD simulations for the geometric model with different simplifications and by comparing the numerical results, the differences caused by the simplifications could be estimated. Our numerical simulations used the RNG k-ε model to solve the air distributions. This study concluded that some cabin geometries, such as the windows and seats, can be greatly simplified. Simplification could significantly reduce the grid number that makes the simulations faster.

- Plasmonic Fano resonances (FRs) in nanostructures have been extensively studied in recent years. Nanorod-based complexes for FRs have also attracted much attention. The basic optical properties and fabrication technology of different kinds of plasmonic nanorods have been greatly developed over the last several years. The mutipole plasmon resonances and their flexible adjustment ranges on nanorods make them promising for FR modifications and structure diversity. In this paper, we review some recently studied plasmonic nanorod based nanostructures for FRs, including single nanorods, dimers, mutipole rods and nanorod-nanoparticle hybrids. The corresponding applications of the FRs are also briefly discussed. This journal is © the Partner Organisations 2014.

- In this paper, we propose a distributed network coding (DNC) scheme based on the Raptor codes for wireless sensor networks (WSNs), where a group of sensor nodes, acting as source nodes, communicate with a single sink through some other sensor nodes, serving as relay nodes, in a multi-hop fashion. At the sink, a graph-based Raptor code is formed on the fly. After receiving a sufficient number of encoded packets, the sink begins to decode. The main contributions of this paper are the derivation of a bit error rate (BER) lower bound for the LT-based DNC scheme over Rayleigh fading channels under maximum-likelihood (ML) decoding, and the derivations of upper and lower BER bounds for the proposed Raptor-based DNC scheme on the basis of the derived BER bound of LT codes.
