Linear elastic mesh deformation via localized orthotropic material properties optimized by the adjoint method
… and fluid dynamics. However, achieving the high orders of accuracy easily available to the finite element method has proven difficult due to conforming higher-order meshes to curved geometries. If higher-order nodes are not placed on the surface of the geometry error is introduced into the …

Novel photonic phenomena in nanostructured material systems with applications and mid-range efficient insensitive wireless energy-transfer
… and to support dispersionless (to unusually-high orders) broadband-slow or stopped subwavelength light, by utilizing a simple planar multilayered dielectric structure. This platform can achieve a significant reduction in all (temporal, spatial and energy) light-scales and could enable compact …

Analysis and design of high order digital phase locked loops
… particularly the behaviour and stability of high order PLL systems. This thesis presents a new design technique for high order Digital PLL (DPLL)systems with a charge pump phase frequency detector component, offering an alternative to the common design practice which is to analyze the DPLL …

Design and Implementation of Complexity Reduced Digital Signal Processors for Low Power Biomedical Applications
… phase Finite-Impulse-Response (FIR) filters with high orders that in-crease the hardware complexity [1–5]. In this thesis, the novel use of minimum phase Infinite-Impulse-Response (IIR) decimators is proposed where the hardware complexity is massively reduced compared to the conventional FIR …

Étude numérique et expérimentale du comportement non linéaire des plaques perforées en présence d’écoulement
Cette thèse étudie expérimentalement la réponse acoustique de plaques macro-perforées (pourcentage de surface ouverte (POA) jusqu’à 40% et diamètre jusqu’à 3 mm), en présence d’un écoulement rasant et soumis à des niveaux de pression acoustique (SPL) élevés jusqu’à 180 dB. Tout d’abord, une méthode …
