Delay-Dependent Robust Asymptotically Stable for Linear Time Variant Systems
In this paper, the problem of delay dependent robust asymptotically stable for uncertain linear time-variant system with multiple delays is investigated. A new delay-dependent stability sufficient condition is given by using the Lyapunov method, linear matrix inequality (LMI), parameterized first-order model transformation technique and transformation of the interval uncertainty in to the norm ...
متن کاملAllophone-based acoustic modeling for Persian phoneme recognition
Phoneme recognition is one of the fundamental phases of automatic speech recognition. Coarticulation which refers to the integration of sounds, is one of the important obstacles in phoneme recognition. In other words, each phone is influenced and changed by the characteristics of its neighbor phones, and coarticulation is responsible for most of these changes. The idea of modeling the effects o...
متن کاملFuzzy adaptive tracking control for a class of nonlinearly parameterized systems with unknown control directions
This paper addresses the problem of adaptive fuzzy tracking control for aclass of nonlinearly parameterized systems with unknown control directions.In this paper, the nonlinearly parameterized functions are lumped into the unknown continuous functionswhich can be approximated by using the fuzzy logic systems (FLS) in Mamdani type. Then, the Nussbaum-type function is used to de...
متن کاملInterpretive Structural Modeling of Urban Development Empowerment
Cities are centers of technology-based transformations and play pivotal role in economic procedures. Moreover, cities are the social, cultural pivots and center for political challenges either in peace or violence and war. Cities possess a distinguishing share in societies’ economic growth and development. Future of the development of the developing countries is concentrated in cities. Theref...
متن کاملVelocity Modeling in a Vertical Transversely Isotropic Medium Using Zelt Method
In the present paper, the Zelt algorithm has been extended for ray tracing through an anisotropic model. In anisotropic media, the direction of the propagated energy generally differs from that of the plane-wave propagation. This makes velocity values to be varied in different directions. Therefore, velocity modeling in such media is completely different from that in an isotropic media. The vel...
متن کاملCardboard People : A Parameterized Model of Articulated I
We extend the work of Black and Yucoob on the tracking and recognition of human facial expressions using parameterized models ($optical $ow to deal with the articulated motion of human limbs. We define U "cardhoard perJon model" in which a person's limbs are represented b y U set of connected planar patches. The pcm"er ized image motion of these patches is constrained to enforce articulated mot...
