Patient-specific Glucose Metabolism Models for Model Predictive Control of T1DM Glycemia

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

Wave splitting of the Timoshenko beam equation in the time domain

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

Crystal Structures in GaAs Nanowires: Growth and Characterization

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

Comparison of LTI and Event-Based Control for a Moving Cart with Quantized Position Measurements

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

Application of Software Design Patterns to DSP Library Design

The design of a hardware data path library is one of the harder problems in design for reuse. Due to the appearance of hardware modeling libraries based on C++, it is possible to apply advanced software techniques to design such a library. This paper shows how software design patterns can be applied to hardware design. Design patterns yield a twofold advantage: a faster design process, and a libra

Evaluating automated support for requirements similarity analysis in market-driven development

In market-driven software development, there is a considerable risk for congestion in the requirements engineering process, as the demand of short time-to-market is combined with a rapid arrival of new requirements from many different sources. Automated analysis of the continuous flow of incoming requirements provides an opportunity to increase the efficiency of the requirements engineering proces
