In order to study the impact of different shapes of thread section on inverse identification, the technique of parameter inverse identification based model contrast methodology was conducted in this paper, and the thread material parameters of rectangle section was identified, and then this set of parameters was adopted in finite element model with thread section shape of triangle, zigzag and trapezoid...
High-speed train control system is one complex security system with lots of functions, which means that it is necessary to build up high-speed train control system simulation & testing integration platform to start function and system verification and validation (V&V). In this paper, key techniques of high-speed train control system simulation & testing integration platform are studied;...
Relevance feedback is an iterative search technique to bridge the semantic gap between the high level user intention and low level data representation. This technique interactively determines a user's desired output or query concept by asking the user whether certain proposed 3D models are relevant or not. For a relevance feedback algorithm to be effective, it must grasp a user's query concept accurately...
We propose a new algorithm, called the central difference filter - Kalman filter (CDF-KF) for conditionally linear Gaussian state space models. The linear state equation is firstly inserted into the measurement equation, and the CDF is applied to the new measurement and the nonlinear state equations to estimate the nonlinear states, where after the estimated means of the nonlinear states are substituted...
A new mathematical tool, the geometric algebra of Euclidean 3-space (G3), is introduced for electromagnetic vector-sensor array processing herein. This paper focuses on modeling the six-component outputs of a vector-sensor holistically by an entry called as a multivector in G3. A compact polarized model for the array, termed as a geometric algebra model (G-MODEL), is then presented. Using the G-MODEL,...
