Recent work has highlighted the benefits of exploiting robust Capon beamformer (RCB) techniques in passive sonar. Unfortunately, the computational requirements for computing the standard RCB weights are cubic in the number of adaptive degrees of freedom, which may be computationally prohibitive in practical situations. Here, we examine recent computationally efficient techniques for computing the
Using exact dispersion relations for electromagnetic wave propagation in layered, periodic media, consisting of two phases, we derive explicit asymptotic solutions for small wavenumbers. These solutions are compared to the numerical solutions of the exact dispersion relations, and applications to homogenization problems are discussed. The results can be used as test cases for homogenization techni
The development of a predictive control algorithm for glycaemia regulation in diabetic subjects requires patient-specific models of the glucose metabolism which are physiologically relevant, parsimonious, yet able to accurately forecast blood glucose. Given the measured data: total plasma insulin [mIU/L]; plasma glucose [mg/dL]; plasma glucose rate of appearance after intestinal absorption [mg/kg
In recent years, wave splitting in conjunction with invariant imbedding and Green’s function techniques has been applied with great success to a number of interesting inverse and direct scattering problems. The aim of the present paper is to derive a wave splitting for the Timoshenko equation, a fourth order PDE of importance in beam theory. An analysis of the hyperbolicity of the Timoshenko equat
With their nanometer size cross-section and high aspect ratio, semiconducting nanowires have properties that make them promising as building blocks in future electronic and optoelectronic devices. Because of their small size, their optical and electrical properties can differ from their bulk counterparts, and their geometry allows for material combinations not accessible in thin films. Moreover, n

Traditional linear time-invariant (LTI) control design assumes that measurements are taken at regular time intervals and have independent additive noise. A common practical case that violates this assumption is the use of encoders that give quantized position measurements; when the quantization is appreciable the measurement noise is far from LTI. This paper develops a simple event-based controlle
