چکیده

Due to the increasing number of power electronics-based devices in modern systems, there are concerns about impact higher-frequency interactions on system stability. The typically-used algebraic representation networks fails capture these newly emergent issues, but dynamically modelling entire network with differential equations will lead a prohibitively long simulation time. This paper proposes computationally-efficient analysis framework determine loadability electronics-rich, large consideration multiple types stabilities. developed this identifies critical elements based eigenvalue sensitivity order exploit hybrid approach. Within model, only portion is modelled rest represented by equations. Bifurcation theory used simultaneously analyze both small-disturbance rotor angle and voltage results obtained show that high-frequency accurately captured proposed framework. Additionally, applying methodology small dimension for matrix reduction computational burden. Two test networks, three-bus IEEE 39-bus system, illustrate verify

A Hybrid Framework for Building an Efficient Incremental Intrusion Detection System

In this paper, a boosting-based incremental hybrid intrusion detection system is introduced. This system combines incremental misuse detection and incremental anomaly detection. We use boosting ensemble of weak classifiers to implement misuse intrusion detection system. It can identify new classes types of intrusions that do not exist in the training dataset for incremental misuse detection. As...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
