It is a problem needs to overcome that steel rails induce eddy current when the maglev train runs. Most of the existing studies are about lower speed operations, and there are few studies aim at the situation of EMS high-speed maglev train. This paper simplifies the construction of EMS high-speed maglev train, simulates it by electromagnetic field simulation software Ansoft Maxwell, and researches...
Gesture as a natural and efficient interactive mode, which has been widely used in the field of human-computer collaboration, as the present existing gesture acquisition method is difficult to meet the users' immersion experience and ensure the real-time requirements, in this paper, we design a wearable interactive system which can meet the need of real-time hand gesture acquisition and 3D display...
The ion selectivity of nanochannel due to the wall surface charges is capable of inducing strong coupling between fluidic and ionic motion within the system, which has been overlooked in the study of nanofluidics. This interaction opens up the prospect of operating nanochannel as nanoscale devices for electrokinetic energy conversion. However, the very short channel lengths make the ionic movement...
In this paper, we propose a path planning framework for underwater exploration and rugosity estimation using Autonomous Underwater Vehicles (AUVs). Rugosity, a measure of variation in the height of a surface, is commonly used to characterize seafloor habitat. The goal of this work is to optimize the survey of an unknown area in order to efficiently estimate its rugosity. To this end, we propose a...
An approach to studying composite EM scattering from 2-D rough surface and half-buried 3-D target is proposed in this paper, from accurate geometry modeling to RCS analysis. First, two dimensional rough surface is simulated with spectral method, which then is converted into a continuous curved surface through inverse engineering. Target model and rough surface model are combined together to be a very...
cataclastic structure rock mass is very common in superficial geological body whose stress-strain law closely concerned with the structural plane. Based on one-dimensional constitutive model presented by Professor GZ-Sun for cataclastic structure rock mass, a three-dimensional constitutive model is established in the paper, and then the model is embedded into FLAC3D by using its user defined model...
The testing system based MEMS inertial devices is a kind special measurement system which is integrated with MEMS inertial sensor, ASIC and its corresponding software. Because of having merits such as small bulk, low cost, light weight, high reliability, and anti-harsh environments, it is widely used in the military and civil fields, especially suited for the high-g guided ammunition, but use what...
In a project that numerous perception sensors consisted of accelerometers and gyroscopes will be integrated into a MIMU (Micro Inertia Measurement Unit) to measure the missile’s 3D motion data. In order to improve the development process, secure the test phase, and also to watch the missile’s 3D motion remotely after the real missile sending experiment, a simulation environment is mandatory. This...
Numerical method which can accurately predict pump's performance has been obtained in this paper. Flow in centrifugal pump equipped with a conical suction, a conical suction with swirl stop, and a center baffle suction has been simulated respectively. With comparison of the pump performance curves, it indicates that the three suctions almost have the same effect to the pump, and the center baffle...
In this paper, a Product Integrated & Collaborative Design Methodology Based on Virtual Product Prototypes (PICD) is explored. In PICD, A Product Master Model (PMM) is used as a product shared information database, which is also integrated product information model of a Virtual Product Prototype (VPP). A VPP is used to view the product during design process before creation of any physical prototype,...
To realize accurate recognition of human activities, many studies have been proposed using vision sensors. Vision sensors can reliably detect human in normal environment, but it is affected by sudden illumination changes and complex conditions, which are the major obstacles to the reliability and robustness of the system. To solve this problem, we proposed a novel integration method to combine bi-static...
