The Nonlinear Autoregressive Moving Average with eXogenous inputs(NARMAX) approach is briefly introduced. Since its advantage on nonlinear system modeling, this paper focuses on its application for describing the dynamic energetic electron flux(>2MeV)variations at the geostationary orbit. A basic one-step-ahead nonlinear model and a Kalman Filter modified one are built to map the relationship between...
This research adopts empirical approach to investigate structure features of employees' silence in interests' expressions (ESIE) and its coping styles. The result shows that in organizations, the interests of employees are related to four aspects: survival, development, relationship, and the interest of value inclination; the ESIE mainly are negative cognition; the ESIE includes: cognitive silence,...
Evaluation of groundwater environment carrying capacity is a multi-objective, multi-criteria and multi-level comprehensive issue. Evaluation index system of groundwater environment carrying capacity was built and divided into some subsystems in accordance with each index's inherent stratification link. Every index's effect on carrying capacity system was obtained by normalization operations catastrophe-based,...
It is a multi-objective, multi-criteria, multi-level and high-dimensional comprehensive issue to assess groundwater resources and environment carrying capacity affected many factors. Projection pursuit (PP) technology was adopted to reduce dimension of the above non-linear and high-dimensional problem. Particle swarm optimization (PSO) algorithm was introduced to optimize projection index function,...
In this paper, provides three assumptions about the relation between human resource development and advanced manufacturing technology based on a detailed analysis of their relationships, and then build human resource development and advanced manufacturing technology index system in accordance with international manufacturing strategy survey (IMSS) database. We further apply analysis of variance and...
Grey incidence model is an important part of grey system theory on the basis of grey decision-making and grey cluster. A new grey incidence model is constructed by gradual tempo difference between sequence and relevant sequence based on the analyzing traditional grey incidence models. Meanwhile, the new model has some characters. A real example is presented to illustrate its simplification and practicability.
The characteristics of "poor" information in database and the requirement of "poor" information data mining are analyzed. Based on gray trend relational degree and general system theory, the model of gray trend relational system is investigated. As an application of this model, the gray trend clustering method is presented. Based on the scanty data of some examination papers in...
The quality of fingerprint images highly affects the performance of Integrated Automated Fingerprint Identification Service. An effective method is essential to enhance the fingerprint image. Based on the study of intrinsic feature of fingerprint images, we propose a new approach for fingerprint image enhancement via contourlet transform in this paper. Our method is adaptive for orientation estimation...
