This paper constructs a dynamic stochastic general equilibrium (DSGE) model which incorporates money by MIU (Money-in-the-Utility Function) approach, and applies it to Chinese business cycle model analysis from 1996 to 2005. The comparison of simulation results and actual data implies that the model can reflect economic fluctuations. Quantitative analysis demonstrates that technology shock and money...
Using two related empirical models, this article estimates the effects of foreign patent applications and intellectual property protection on Chinese technology progress. The results suggest that foreign patent applications have positive effects on Chinese technology progress, but it is smaller compared with the effects of Chinese domestic R&D inputs. Intellectual property protection increases...
The exact prediction of rockburst is an urgent problem for the underground excavation in high geostatic stress environment. Set pair analysis (SPA) and variable fuzzy sets (VFS) are new methodologies to describe and process system uncertainty. In this paper, a novel model using the theory of SPA is proposed to construct the difference function of VFS by means of approaching degree between the sample...
This paper introduces the control strategy and method of non-linear dynamic inversion. Depending on the thought of dynamic inversion, the mathematical model of super-maneuverable aircraft is set up and the simulation curves are produced. Through analyzing the curves, we can draw out the feasibility and limitation of non-linear dynamic inversion.This paper introduces below contents :the feasibility...
The car-following traffic flow model proposed by Bando et al. is modified by adding an acceleration-adjustment term. Moreover this modified model is extended by incorporating multi-vehicle characteristics. Analysis of linear stability on circuitous road is done. Numerical simulations for two-type-vehicles traffic systems and three-type-vehicles traffic systems show that the growth and decay of a small...
This paper studies on dynamic order strategy for auto spare parts on a target service level. A new three-dimensional classification is proposed integrated order policy of spare parts. It improves the present the weakness of ABC classification and combines with three control variables influenced the order policy, X demand, Y item price and Z variation of demand, to classify all spare parts. Unlike...
As permanent magnet synchronous motor (PMSM) has the characteristics of high power density, high efficiency, and high torque current units, so it is extensively used in electric vehicles driving. Energy management unit (EMU) in hybrid electric vehicle (HEV) demands for good motor driving and energy regeneration capability. Based on the mathematical model of PMSM, this paper presents the PMSM vector...
A new robust watermarking 3D mesh model algorithm is presented in this paper. We embed two different watermarks into a 3D mesh. One of the two watermarks is based on feature information and another is embedded by Nielson norm. The two watermarks do not disturb each other. Since the algorithm is blind, it does not need the original model during extraction. The algorithm is applied to many mesh models...
An algorithm is presented to absolutely registration two 3-D sensors using targets that are tracked by both sensors. The algorithm estimates and removes sensor biases and sensor frame orientation errors, For illustrative purposes, the algorithm uses the difference in the position of a target, as reported by the two sensors, to compute a set of bias parameters. These bias parameters are then applied...
In order to overcome the disadvantage that only one solution can be found in particle swarm optimization (PSO), a novel niche particle swarm multi_optimizer (multi_PSOer) which combines two strategies is devised in this paper. Firstly, guaranteed convergence PSO (GCPSO) is adopted to guarantee the algorithm can converge on a local point. Secondly, niche technique is used to ensure the algorithm is...
An algorithm using finite difference to digitize a wave equation is introduced for the simulation of sound propagating in different sound intermediate. Simulation system according to algorithm is achieved using VC on a Windows 2000 platform. Simulation model according to actual noise-proof board situation in double driveway is built. Calculation project is designed to get the test result of different...
To solve the problems in modulation recognition of time-frequency overlapped two-signal in the single-channel, an algorithm based on cyclic cumulants used modulation recognition is presented. Through computing the fourth-order cyclic cumulants of pretreated band signals, the feature vector for classification was extracted, and then use the minimum-error criterion to classify time-frequency overlapped...
Round-Robin scheduling is the most popular time triggered scheduling policy, and has been widely used in communication networks for the last decades. It is an efficient scheduling technique for integration of unrelated system parts, but the worst-case timing depends on the system properties in a very complex way. The existing works on response time analysis of task scheduled under Round-Robin determine...
DC-DC converters are the kernel parts in the switching power supplies. There are abundant dynamical behaviors in them. In order to discover all these linear and nonlinear phenomena, it is demanded to put forward some appropriate modeling methods. This article discusses the modeling methods, which aimed at some familiar DC-DC converters under the control of voltage and current mode. They include exact...
