As the development of civil aviation, the aircraft noise pollution turned into a serious environmental problem in China. There are more than 100 airports at the end of 2015. In the Thirteen Five Plan of China, the government plans to build more than 500 general airports. Airport noise management and control will be a huge challenge. Environmental noise impact assessment for airport is key procedure of noise control. This paper used Beijing New Airport as an example, analyst various influence factors of airport noise. © 2016, German Acoustical Society (DEGA). All rights reserved.

This paper investigates the modified function projective synchronization, which means that the drive system and the response system are synchronized up to a desired scale matrix of function. By the active control scheme, a general method for modified function projective synchronization is proposed. Numerical simulations on chaotic Rössler system and hyper-chaotic Chen system are presented to verify the effectiveness of the proposed scheme.

Aiming at the disturbance of the roll and bar on the luggage to the automatic detection of contraband goods in the X-ray baggage security inspection process, a method to recognize the roll and bar on the luggage is studied. A method to recognize the bearing of the roll is used to locate the coordinates. According to the coordinate, the image is affine transformed and detect the lines, an integrated projection method is eventually used to recognize the bar regions. The test results prove that the method is effective to recognize the roll and bar on the luggage, and is useful for increasing the automatic detectable precision of contraband goods of the X-ray detector.

This Paper investigates the modified function projective synchronization (MFPS) of two different chaotic systems with parameter perturbations. The parameter perturbations are assumed to appear in both drive and response systems, which perturbed about the nominal parameter values. Based on the robust control techniques, the robust control law is proposed, which is able to overcome random uncertainties of all model parameters. Corresponding numerical simulations are performed to verify the analytical results. © 2012 IEEE.

Estimation of departure passenger flow is one of the prerequisites to optimize the airport terminal resources so as to meet the dynamic travel demand. This paper proposes a simulation based approach to address this problem. Firstly, the number of passenger for each scheduled flight is estimated. Secondly, the behavior of each passenger of the flight is simulated by randomly generating the departure time instant at several key stages of departure process based on the probabilistic distribution. Then, the number of passengers for each time interval can be counted with the above simulated time. The efficacy of the proposed approach is validated through the real-world data collected from Beijing Capital International Airport. © 2015 IEEE.

In this paper, the direct impact, indirect impact and induced impact are used to analysis the economic benefit of the Beijing Capital International Airport (BCIA). The representative airports, Atlanta Airport, Dallas-Fort Worth Airport and John F. Kennedy International Airport are selected to compare with the BCIA in the aspects of total impact and direct impact. Some foreign organizations regularly measure certain areas’ economic and social impact generated by the airports. BCIA is compared with a series of areas in Asia Pacific and the UK in several respects. © (2014) Trans Tech Publications, Switzerland.

Active fault is one of the main geological hazards for long-distance transportation pipeline. Ground movement caused by faults may cause large strain in pipe in the potential of leading to failures and accidents. Using loose granular sand backfill is a common aseismic measure for buried steel pipelines in seismic areas. In this paper, a rigorous finite element model for pipeline crossing active fault was established, in which the pipe and soil were simulated by shell and solid elements respectively. The pipe soil relationship is accurately considered by surface to surface contact algorithm. Effects of the geometrical trench size parameters on pipe strain were discussed in detail. Results show that the buried depth of pipeline and the slope of pipe trench are the main factors affecting the pipe strain. In the design of pipe trench, the minimum allowable value of pipe buried depth is recommended, the pipe trench slope less than 1 is preferred, and the widening allowance of the bottom of pipe trench does not need special treatment. This study can be referenced in the aseismic design of buried pipelines in seismic areas. © 2016 ejge.

Queuing is common in urban public places. Automatically monitoring and predicting queuing time can not only help individuals to reduce their wait time and alleviate anxiety but also help managers to allocate resources more efficiently and enhance their ability to address emergencies. This paper proposes a novel method to estimate and predict queuing time in indoor environments based on WiFi positioning data. First, we use a series of parameters to identify the trajectories that can be used as representatives of queuing time. Next, we divide the day into equal time slices and estimate individuals average queuing time during specific time slices. Finally, we build a nonstandard autoregressive (NAR) model trained using the previous days WiFi estimation results and actual queuing time to predict the queuing time in the upcoming time slice. A case study comparing two other time series analysis models shows that the NAR model has better precision. Random topological errors caused by the drift phenomenon of WiFi positioning technology (locations determined by a WiFi positioning system may drift accidently) and systematic topological errors caused by the positioning system are the main factors that affect the estimation precision. Therefore, we optimize the deployment strategy during the positioning system deployment phase and propose a drift ratio parameter pertaining to the trajectory screening phase to alleviate the impact of topological errors and improve estimates. The WiFi positioning data from an eight-day case study conducted at the T3-C entrance of Beijing Capital International Airport show that the mean absolute estimation error is 147 s, which is approximately 26.92% of the actual queuing time. For predictions using the NAR model, the proportion is approximately 27.49%. The theoretical predictions and the empirical case study indicate that the NAR model is an effective method to estimate and predict queuing time in indoor public areas.
