Building a human-computer interactive parachute simulator is an efficient way to avoid the high risk and high cost of field parachute training. In this paper, a novel dynamic recognition and simulation approach of parachute training is developed. Firstly we process the skeletal data acquired by Kinect and enforce the indication of the trainees' parachute posture, where principle component analysis...
An image degraded by noise is a common phenomenon. In this letter, we propose a novel adaptive fuzzy switching weighted mean filter to remove salt-and-pepper (SAP) noise. The process of denoising includes two stages: noise detection and noise elimination. In the first stage, pixels in a corrupted image are classified into two categories: original pixels and possible noise pixels. For the latter, we...
Based on part of the research results of uncertainty theory, this paper, under two conditions of fuzzy random demand and random rate, respectively in-depth investigated the coordination model of three-stage supply chain which dominated by manufacturer and consisted by supplier, manufacturer and retailer. In this paper, we established the optimal strategy model and compiled the hybrid intelligent algorithm...
Simulation of flow field over mountains usually plays an important role in atmospheric dynamics and engineering application, and some of its modeling methods are reviewed in this paper. Aiming at studying the flight dynamics of fixed wing vehicles passing through complex terrains, an engineering and three-dimensional (3D) simulation method based on potential fluid theory is modified in this paper...
Path planning is a significant problem in mission planning. For Miniature Air Vehicles (MAVs) exposed to strong winds, their flight paths are dynamically influenced by wind. Moreover, the small payload of MAVs severely restricts on-board computational resources. To alleviate the computational burden, a multi-resolution path planning approach for MAVs is presented, which is considering the knowledge...
This paper focuses on an intelligent decision-making model of surface warship modeling in Computer Generated Forces (CGF) System. Different kinds of AI technologies were used to found the decision-making model, enable the surface warship CGF system to select battle region, layout path, identify targets, estimate threat and control firing. The model was validated through simulating with other CGF systems...
In order to enhance the indication performance of Tunnel-in-the-Sky (TIS) in the flight instrument to assist the pilots' operation, flight operation-oriented strategies for tunnel are advocated. Dynamic driving strategy for tunnel is proposed to generate tunnel data dynamically, which endows the tunnel with a return-to-path guidance capacity. Transition strategy from the current flight path to the...
According to the consistency test between simulation and flight telemetry data, the credibility of tactical missile simulation model can be effectively verified. To achieve consistency test of dynamic performance based on frequency domain and improve the effectiveness of simulation model validation, the modern spectral estimation method is adopted to analyze the spectrum of dynamic performance of...
Composed of varieties of components representing behaviors from different disciplines, complex product can be described by a group of subsystem models and the interaction between them. Simulation of the product is always performed by different processes located at distributed computational resources with the rate of iteration different and inter-process communication intense. A simulation framework...
A hardware-in-the-loop simulation (HILS) system is presented for mid and terminal guidance simulation of precise imaging auto target recognizing (ATR) missiles. The system provided a simulation platform supporting the researches of ATR theories and designations of remote precise missiles. This distributed HILS system uses a multi-solution communication architecture between nodes of different real-time...
Synthetic natural environment (SNE) data is different from the general entity data. SNE data are data-field changing with time and space. The hierarchical synthetic environment database system was designed according to the SNE data characteristics and the simulation application needs. The SNE database system included primary environment database, standard environment database compatible with synthetic...
