Fast Adaptive Laws for Adaptive Control Under Stochastic Disturbances
In this work, we consider two classes of adaptive laws for the adaptive control of a class of discrete-time nonlinear systems with all states accessible perturbed by a stochastic disturbance. First, we consider high-order tuner algorithms based on accelerated gradient methods for the optimization …

Adaptive Brake By Wire: From Human Factors to Adaptive Implementation
… could be highly improved by means of adaptive pedal feelings. The starting points of this research were humans factors in the braking domain. Literature and relevant studies have been taken into consideration to put into evidence human mechanisms and behaviors during braking phases. On …

Adaptive parameter servers
… in this direction, each making the PS more adaptive. In particular, we explore (i) to dynamically adapt the allocation of model parameters, i.e., to relocate parameters among nodes during training, according to where they are accessed, (ii) to adapt the management technique of the PS to the …

Adaptive defibrillator design
… adjustment of the TTR has not been attempted (adaptive defibrillation). In this thesis, a method is described for implementing such an adaptive defibrillator by control of the defibrillator current.

Adaptive video segmentation
The efficiency of a video indexing technique depends on the efficiency of the video segmentation algorithm which is a fundamental step in video indexing. Video segmentation is a process of splitting up a video sequence into its constituent scenes. This work focuses on the problem of video …

Homeostatic adaptive networks
… homeostasis and develop a theory of homeostatic adaptive systems. We study homeostatic adaptive networks by looking at specific examples of homeo-static systems: the Homeostat, homeostatic plasticity in neural networks, and homeostatic regulation of the environment by the biota. Investigation of …

Multivariable Adaptive Control
This thesis treats the problem of direct adaptive control of linear multivariable systems. The parametrization problem of adaptive control is discussed extensively. A pole-placement problem and a model-matching problem are formulated and interpreted in terms of model reference control. The problem …

Adaptive Robust Control
… we present a novel approach to the problem of adaptive robust control. The essential idea involved is to fragment the modeling uncertainty in a physical plant into "small" families of plant models for which robust linear time-invariant controllers can be readily designed. We then implement a …

Rethinking adaptive reuse
Adaptive reuse of manufacturing plants in post-industrial countries has become an increasing trend. In the United States, evidence of our industrial past is present in both urban and rural landscapes. The appearance of "brownfields" is due to the change in the U.S. economy from heavy industry and …

Adaptive vibration absorber
Rapid changes in the drafting profession have left gaps in skills and resources which hinder the ability of community college drafting instructors to provide students with the advanced skills needed for employment. To minimize these problems and to facilitate the integration of CAD into drafting …

Adaptive Preference Tradeoffs
… practitioners and political philosophers call an adaptive preference (AP): a preference, formed under oppressive circumstances, that seems to perpetuate the agent’s own oppression. Prevailing opinion is that forced tradeoffs—especially following Serene Khader’s taxonomy—, like the case presented …

The Adaptive Optics Lucky Imager: combining adaptive optics and lucky imaging
… were obtained by combining the techniques of adaptive optics and lucky imaging. The Adaptive Optics Lucky Imager (AOLI), being developed at Cambridge as part of a European collaboration, combines these two techniques in a dedicated instrument for the first time. The instrument is designed …

Adaptive intelligence: Integrating recurrence, deep reinforcement learning, and neuro-adaptive techniques for dynamic unified guidance & control of adaptive systems
Submission original under an indefinite embargo labeled 'Open Access'. The submission was exported from vireo on 2024-03-01 without embargo terms

Simulation of Adaptive Array Algorithms for OFDM and Adaptive Vector OFDM Systems
… intersymbol interference (ISI). Deploying an adaptive antenna array at the receiver can help separate the desired signal from interfering signals which originate from different spatial locations. This enhancement of signal integrity increases system capacity. In this research, we apply …

Query-driven adaptive sampling
… develop a single approach for a broad range of adaptive sampling missions with risk and limited prior knowledge. To achieve this, we present contributions in planning adaptive missions in service of queries, and modeling multi-attribute environments. First, we define a query language suitable …
