Graphical model driven methods in adaptive system identification
Identifying and tracking an unknown linear system from observations of its inputs and outputs is a problem at the heart of many different applications. Due to the complexity and rapid variability of modern systems, there is extensive interest in solving the problem with as little data and …

Modeling an Adaptive System with Complex Queuing Networks and Simulation
An adaptive system differs from a non-adaptive system in that an adaptive system uses a specific process to identify and implement adaptations to system parameters during run time in an effort to increase system performance.;In order to develop an adaptive system one of the most important aspects …

Stochastic adaptive system theory for identification, filtering, prediction and control
… asymptotic properties of various stochastic adaptive systems for identification, filtering, prediction and control. These include the convergence of long-term averages of signals of interest (self-optimality), the convergence of adaptive filters or controllers (self-tuning property), the …

Humanitarian Intervention at Mt. Sinjar, Iraq: A Complex Adaptive System Analysis
… to existing civil-military frameworks. Complex Adaptive System (CAS) analysis is used to explain actions in a non-hierarchical environment. Salient strategies that worked to produce a positive humanitarian outcome at Mt. Sinjar are identified. The results suggest that only the humanitarian …

Speed sensorless field oriented control of ac induction motor using model reference adaptive system
… is used as a feedback for the vector control system. The model reference adaptive control system is predicated on the comparison between the outputs of adjustable model and reference model. The error between them is employed to drive a suitable adaptation mechanism which generates the …

To explore the holistic behaviour of the UK Intellectual Property Office using the Complex Adaptive System paradigm
… Intellectual Property Office, using the complex adaptive system paradigm. The study contributes to knowledge and practice through the refinement of the complexity strategy matrix, which portrays organisations as degrees of mechanistic and emergent behaviour. Consequently this understanding of …

An Effective Communication Framework For Inter-Agent Communication In a Complex Adaptive System With Application To Biology
Multi-Agent Systems (MASs) and Partial and Ordinary Differential Equations (PDEs and ODEs respectively) have often been employed by researchers to effectively model and simulate Complex Adaptive Systems (CASs). PDEs and ODEs are reduction based approaches which view the system globally and ignore …

Adaptive restoration of text images containing touching and broken characters
For document processing systems, automated data entry is generally performed by optical character recognition (OCR) systems. To make these systems practical, reliable OCR systems are essential. However, distortions in document images cause character recognition errors, thereby, reducing the …

Graduated Persistent Excitation and steady state margins for adaptive systems
… control architectures such as model reference adaptive control. The first step for the development of Verification and Validation (V&V) techniques for this class of nonlinear control systems is presented in this thesis in the context of controlling uncertain flight vehicle dynamics. Using a …

Real-Time Anticipatory Suspension Control for Single Event Disturbances
… are still equipped with a passive suspension system, while some luxury brands may already use an adaptive suspension. Active suspension systems on the other hand are rarely found, however, they offer great opportunities to close the gap of the well-known trade-off between ride comfort and …

Identifying Complex Adaptive Systems Using Quantitative Approaches At A Midsized Biotechnology Firm
… upgrade to detect the presence of a complex adaptive system, the fundamental component of complexity. Results showed that after the upgrade, animal care technicians did not significantly increase their collective efficiency; instead, they appeared to significantly increase their collective …

Robustness of adaptive control systems to unmodeled dynamics : a describing function viewpoint
… it was shown that a standard model reference adaptive controller modified with a suitably tuned projection algorithm ensures robustness (global boundedness) of the overall adaptive system to a class of unmodeled dynamics with minimal restrictions. However, extensive first-principle based …

Adaptation For Multi-Antenna Systems
Previous attempts to adapt MIMO systems in the presence of varying channel conditions typically focus on characterizing the performance of a limited and predefined set of joint MoDem/CoDec and MIMO configurations over a representative set of channel realizations. Other work has attempted to adapt …
