An optimization method of aircraft periodic inspection and maintenance on the zero-failure data analysis is proposed to effectively solve excessive maintenance in this work, and decrease aircraft unserviceable time. This method includes optimization object analysis, failure distribution recognition, zero-failure data analysis by confidence limit optimal estimate and nonlinear programming solving failure...
As a key structure in an aircraft, rudder is employed to steer the flight vehicle under the instructions of center control unit. There are three main components in rudder: actuator, transmission, and control surface. Power is usually transmitted from the actuator to the control surface via the transmission. To some degree, the performance such as the efficiency and rigidity of rudder is directly determined...
In this paper, we propose a new algorithm for image re-ranking in web image search applications. The proposed method focuses on investigating the following two mechanisms: 1) Visual consistency. In most web image search cases, the images that closely related to the search query are visually similar. These visually consistent images which occur most frequently in the first few web pages will be given...
A simplified parallel finite difference time domain algorithm is brought out based on 1-ranked Debye equation by nonlinear levenberg-marquardt least-squares curve fitting method. A safety threshold with respect to spatial average and spatial peak specific absorption (SA) is proposed, a shielded cockpit glass construction is designed, and specific absorption calculation for pilot in an aircraft is...
Chaotic Ant Swarm is a recently new and promising algorithm of Optimization Problem based on the chaotic theory and foraging food processing of ants. This paper proposes a Multi-Objective Optimization version of CAS, named MOCAS, by changing the colony behavior organization. The proposed algorithm also introduced a re-distribution operation that ensures the uniform distribution of final result. We...
This paper analyzes the equilibrium properties of the morning commuting pattern in a many-to-one corridor network. In the equilibrium state of the multi-origin corridor, no commuter can reduce his/her total commuting cost by unilaterally changing his/her arrival time or departure time. It is found that commuters living closer to the workplace always join the traffic cohorts of those who live farther...
A redundancy design strategy based on component's fault model of device was proposed for distributed control system (DCS). This paper analyzed component's fault model of typical device based on the characteristic of DCS, sorted the faults of components according to the feature which is individual and diagnostic online between the faults of redundancy devices, and put forward the invalidation rate...
In this paper, an articulatory speech synthesizer based on fluid dynamic principles is presented. The key idea is to devise a refined speech production model based on the most fundamental physics of the human vocal apparatus. Our articulatory synthesizer essentially contains two parts: a vocal fold model which represents the excitation source and a vocal tract model, which describes the positions...
