Authors: Wang Jing Yi , Bai Yu Kun
Published: September 2014

In this paper, the difference of core-mode effective refractive indices (RIs) and the long-period fiber grating (LPFG) resonant wavelength in an uniaxial-crystal fiber resulted from two fiber analysis models were demonstrated and analyzed. The two models are two-layered medium model which is normally used for conventional single-mode optical communications fiber and three-layered medium model. Using Transfer Matrix Method (TMM) based on Coupled-Mode Theory (CMT), the different dispersion properties of chirped long-period fiber gratings (CLPFG) calculated by both models were compared. The result shows that the difference of the core-mode effective RIs is significant especially when the cladding radius and cladding mode order are small, which indicates the limitation of the two-layer model, and that reducing the cladding radius and increasing the cladding mode order can improve the CLPFG dispersion compensation capability effectively. This paper provides guidance to the design and accurate analysis of CLPFG based dispersion compensator (DC).

Published: September 2014

With the development of public transport, many cities in China have adopted bus lanes as a preferred method to alleviate the problems associated with high traffic demand and congestion. However, especially in the intersections, permanent dedication of one lane in the cases with lower frequency of bus services is very inefficient. We put forward a conversion section the bus lane in the upstream of intersection, in which the status of a given section changes according to the presence or not of a bus in its spatial domain: when a bus is approaching such a section, the status of that lane is changed to bus lane, and after the bus moves out of the section, it becomes open to right-turning vehicles. This measure enables to shorten the travel time of the right turn vehicles by 20%, while the speed of the buses will not be affected.

This paper is aimed to evaluate the collision risk in free flight. The collision risk between aircrafts is mostly closely relates to position error, due to which the actual position of the aircraft is different from the displaying position and the former is in the vicinity of the latter. Analyzing error factors closely associated with the risk of collision, such as position error caused by CNS performance, altimeters and CDTI system, and according to the error distribution, the region of actual position of aircraft can be considered as a three-dimensional joint normal probability density ellipsoid. The two adjacent planes can be abstracted into two particles, of which one is based to determine position error ellipsoid, and the other is based to establish collision slab. A free flight collision risk model is established, then simplified by linear transformation according to the principle of relative motion. Using Monte Carlo method of mean of uniform random numbers, given initial state, the collision risk in free flight can be obtained. Numerical results demonstrate the feasibility of this model.

This study proposes a novel auditory brain–computer interface (BCI) based on dichotic listening paradigm, which allows the subject to select a target from two different sound stimulus sequences played in each ear. EEG data from 6 subjects has shown that the amplitude of N200 and P300 elicited by target was significantly higher than that of non-target ones. We found the N2ac component: a negativity wave in the N2 latency range at anterior contralateral electrodes. The target detection accuracy was assessed by support vector machine (SVM). The accuracy based on multiple electrodes is higher than a single electrode. The dichotic listening paradigm can be used for binary-class of brain-computer interface system.

The comprehensive ecological index system for cities of Jilin Province was formed by mean square difference method to analyze the annual level of social development, ecological and environmental development, economic development and comprehensive ecological environment for 4 eco-polluted cities (Jiutai, Dehui, Dunhua, Yanji) during 2002-2012. Then the effect on improving urban ecological environment by building diversion dam was evaluated quantitatively for each city. The comprehensive ecological index values of cities had all represented a smooth upward tendency except a marked growth in 2007. The diversion dam could significantly promote the comprehensive urban ecological environment level for cities of Jiutai, Dunhua and Yanji, but not for the city of Dehui.

Authors: Zhang A Ying , Lu Hai Bao
Published: September 2014

A method of synthesizing the FLG/CNF nanopaper on hydrophilic polycarbonate membrane was investigated. The synergistic effect of few-layer graphene (FLG) and carbon nanofiber (CNF) on the electrical conductivity of shape-memory polymer (SMP) composites reinforced by the FLG/CNF nanopaper was explored. The conductive FLG/CNF nanopaper facilitates the actuation in SMP composite induced by electrically resistive heating. The heat conduction in a nanopaper depends greatly on FLG/CNF network formation. The morphology and structure of the FLG/CNF nanopaper are characterized with scanning electronic microscopy (SEM). The flat surface and tunable network structures observed from the microscopic images indicate that the FLG/CNF nanopaper could have highly conductive property. Detailed structural characterization indicates that the three-dimensional networks of nanopaper, result in both the reduction of thermal contact resistance and the enhancement of conductive property along the thickness.
