Analysis of Vibration by Component Mode Synthesis Method : Part 4, Natural Frequency and Natural Mode (II)

تحلیل مودال با استفاده از روش component mode synthesis (cms) همراه با صحه گذاری تجربی

در این پروژه روش های تحلیل مودال سازه هایی که از چند زیرسازه تشکیل شده اند بررسی شده است. از جمله این روش ها روش سنتز مودها است که ابتدا بطور مختصر تاریخچه فعالیت هایی که در این زمینه تا کنون انجام شده است بررسی شده و سپس الگوریتم های مختلف این روش مورد مطالعه قرار گرفته است. از جمله این الگوریتم ها روش سطوح مشترک ثابت و روش سطوح مشترک آزاد است طوریکه روش اول با دقت بیشتر و تنها برای داده های ت...

Overlapping Component Mode Synthesis

MPEG - 4 Natural Video Coding – Part II

Multimedia commands the growing attention of the telecommunications and consumer electronics industry. In a broad sense, multimedia is assumed to be a general framework for interaction with information available from different sources, including video information. Multimedia is expected to support a large number of applications. These applications translate into specific sets of requirements wh...

A Fault Diagnosis Method for Automaton based on Morphological Component Analysis and Ensemble Empirical Mode Decomposition

In the fault diagnosis of automaton, the vibration signal presents non-stationary and non-periodic, which make it difficult to extract the fault features. To solve this problem, an automaton fault diagnosis method based on morphological component analysis (MCA) and ensemble empirical mode decomposition (EEMD) was proposed. Based on the advantages of the morphological component analysis method i...
