In 1974 R. V. Monopoli published a paper [1] in which he posed the now classical model reference adaptive control problem, proposed a solution and presented arguments intended to establish the solution's correctness. Subsequent research [2] revealed a flaw in his proof which placed in doubt the correctness of the solution he proposed. Although provably correct solutions to the model reference a...

Error management training (EMT) is a training method that involves active exploration as well as explicit encouragement to make errors during training and to learn from them. Past evaluation studies, which compared skill-based training outcomes of EMT with those of proceduralized error-avoidant training or exploratory training without error encouragement, yielded considerable variation in effec...

Many scientific applications and experiments, such as high energy and nuclear physics, astrophysics, climate observation and modeling, combustion, nano-scale material sciences, and computational biology, generate extreme volumes of data with a large number of files. These data sources are distributed among national and international data repositories, and are shared by large numbers of geograph...

We present the first efficient, adaptive oblivious transfer protocol which is fully-simulatable under a simple assumption in the standard model. The sole complexity assumption required is that given (g, g, g, g, Q), where g generates a bilinear group of prime order p and a, b, c are selected randomly from Zp, it is hard to decide if Q = g. In an adaptive oblivious transfer protocol, a sender wi...

With the development of high performance computing and increasing of network bandwidth, more and more applications require fast data transfer over high-speed long-distance networks. Research shows that the standard TCP Reno cannot fulfill the requirement of fast transfer of massive data due to its conservative congestion control mechanism. Some works have been proposed to improve the TCP throug...

In this paper, a moving mesh technique and a non-standard finite difference method are combined, and a moving mesh non-standard finite difference (MMNSFD) method is developed to solve an initial boundary value problem involving a quartic nonlinearity that arises in heat transfer with thermal radiation. In this method, the moving spatial grid is obtained by a simple geometric adaptive algorithm ...

This dissertation mainly focuses on implementation techniques for adaptive switching control. Adaptive switching control can generate bad transients in controller output. These bad transients can be reduced by various bumpless transfer techniques. A new bumpless transfer technique is developed based on slow-fast controller decomposition. This technique is especially well-suited to situations in...

This paper proposes an adaptive controller for a class of multi-input multi-output (MIMO) plants where the number of outputs is larger than the number of inputs, an example of which is very-flexible aircraft (VFA). A dominant presence of model uncertainties and actuator anomalies necessitates an adaptive approach for control of VFA. The proposed controller, denoted as the adaptive SPR/LTR contr...

Understanding speech in the presence of background sound can be challenging for older adults. Speech comprehension in noise appears to depend on working memory and executive-control processes (e.g., Heald and Nusbaum, 2014), and their augmentation through training may have rehabilitative potential for age-related hearing loss. We examined the efficacy of adaptive working-memory training (Cogmed...
