Supervisory Control And Data Acquisition (SCADA) systems represent a vulnerability in vital infrastructures. For example, an electric power system is subjected to intrusions via its SCADA systems; however, the instrumentation provides detectable variations in response to such interference. Presented herein is a strategy that augments state estimation methods using a Hybrid Fuzzy System for faul...

The advances in pervasive communication, sensing and computing of wireless sensor networks technologies are leading to the emergence of wireless sensor-actor networks. The spreading merit of WSAN has led to increasing interest in rendering them with expert knowledge to be smart and autonomous networks, which have the potential to enable a large class of applications in multiple fields. Fusion o...

In the off-grid microgrid cluster, energy storage device is mainly charged and discharged to maintain stability of bus voltage system power balance. Generally, current double closed-loop control fuzzy are adopted for converter. The traditional parameters scale factor quantization in cannot be adjusted real time during operation, resulting slower dynamic response weak anti-interference ability s...

In this paper, we present a general computational and operational framework for the Fuzzy Cognitive Network (FCN), which is a direct extension of Fuzzy Cognitive Maps (FCM). The proposed framework assumes a network operation, which continuously receives feedback from the system it describes and outputs control or decision values. This way, its knowledge is continuously updated making it suitabl...

The complexity involved in the designing of a conventional PI type speed controller for an induction motor is replaced by fuzzy logic controller, synthesized by adaptive neural fuzzy interference system (ANFIS) method. This paper presents a hybrid pulse width modulation (HPWM) algorithm to reduce the steady state ripple in current. The conventional space vector pulse width modulation (CSVPWM) m...

A "Schrodinger cat"-like state of matter was generated at the single atom level. A trapped 9Be+ ion was laser-cooled to the zero-point energy and then prepared in a superposition of spatially separated coherent harmonic oscillator states. This state was created by application of a sequence of laser pulses, which entangles internal (electronic) and external (motional) states of the ion. The Schr...

Support Vector Machine ( SVM ) is widely applied to fault diagnosis of machines. However, this classification method has some weaknesses. For example, it can not separate fuzzy information, particularly sensitive to the interference and the isolated points of the training samples. Besides, it has great demand for memory in calculation. In view of the problems mentioned above, a binary tree-base...

Universal mobile telecommunications system (UMTS) is one of the 3 generation (3G) cell phone technologies. The capacity of UMTS is interference limited. Radio resources management (RRM) functions are therefore used. They are responsible for supplying optimum coverage, ensuring efficient use of physical resources, and providing the maximum planned capacity. This paper deals with admission contro...

In previous studies we first concentrated on utilizing crisp simulationto produce discrete event fuzzy systems simulations. Then we extendedthis research to the simulation of continuous fuzzy systems models. In this paperwe continue our study of continuous fuzzy systems using crisp continuoussimulation. Consider a crisp continuous system whose evolution depends ondifferential equations. Such a ...
