Adaptive radiations are important drivers of niche filling, since they rapidly adapt a single clade of organisms to ecological opportunities. Although thought to be common for animals and plants, adaptive radiations have remained difficult to document for microbes in the wild. Here we describe a recent adaptive radiation leading to fine-scale ecophysiological differentiation in the degradation ...

− The paper presents results of investigation on new adaptive Cyclic A/D Converters (CADCs) behaviour in conditions of possible nonidealities of their components, particularly of their internal ADCs transfer characteristics. The simulation results show that the adaptive CADCs do not require high quality internal components and work properly even when the components characteristics differ signif...

This paper considers application of L1 adaptive output feedback controller to a missile longitudinal autopilot design. The proposed adaptive controller has satisfactory performance in the presence of parametric uncertainties and time-varying disturbances. Simulations demonstrate the benefits of the control method and compare the results to Linear Quadratic Regulator (LQR) and Linear Quadratic G...

We show how to build a UC-Secure Oblivious Transfer in the presence of Adaptive Corruptions from Quasi-Adaptive Non-Interactive Zero-Knowledge proofs. Our result is based on the work of Jutla and Roy at Asiacrypt 2015, where the authors proposed a constant-size very e cient PAKE scheme. As a stepping stone, we rst show how a twoow PAKE scheme can be generically transformed in an optimized way, ...

Precomputed radiance transfer methods compute a global light transport model the transfer function to enable real-time rendering of scenes under dynamic distant illumination for arbitrary viewpoints. Usually this transfer function is represented for directions and surface points that are defined a priori. In this paper, we present a precomputed radiance transfer technique, which adaptively choo...

This paper describes a new interface for a barge-in free spoken dialogue system combining an adaptive sound field control and a microphone array. In order to actualize robustness against the change of transfer functions due to the various interferences, the barge-in free spoken dialogue system which uses sound field control and a microphone array has been proposed by one of the authors. However...

This paper presents a simple adaptive algorithm based on the adaptive notch two-taps filter [1] and the filtered-X LMS algorithm [2], to be used in active noise control applications, The system consists of two adaptive algorithms working together. One algorithm estimates on-line the error path transfer fi.mction as proposed in [3] and the other cancels a i%equency narrowband of the residual sig...

This paper defines haw the quality of approximation used in the error transfer function analysis affects the accuracy of the resulting steady-state mean square error (MSE) of the Least-Mean-Square (LMS) adaptive filters. It shows that the error transfer function approach is very accurate for extremely narrow bandwidth input signals, and it deteriorates as the bandwidth of input signal increases.

The purpose of this paper is to marry the two concepts of Multiple Model Adaptive Control and Safe Adaptive Control. In its simplest form, Multiple Model Adaptive Control involves a supervisor switching among one of a nite number of controllers as more is learnt about the plant, until one of the controllers is nally selected and remains unchanged. Safe Adaptive Control is concerned with ensurin...

We propose a new model reference adaptive control algorithm and show that it provides the robust stability of the resulting closed-loop adaptive control system with respect to unmodeled plant uncertainties. The robustness is achieved by using a relative error signal in combination with a dead zone and a projection in the adaptive law. The extra a priori information needed to design the adaptive...
