Structural, Dielectric, and Magnetic Properties of NiZnCu Ferrites Synthesized by Reactive Spark Plasma Sintering Process

Conventional methods for preparing ferrites are time-consuming processes, which require high temperatures in the order of 1200°C . The reactive spark plasma sintering method is a more rapid procedure involving lower temperatures. Different…

Rotational magnetic losses in non-oriented Fe-Si and Fe-Co laminations up to the kHz range

Literature data on the energy loss behavior of steel sheets under rotating induction are restricted to quite low frequencies, i.e. up to a few hundreds of hertz. This is not sufficient to predict the loss in high-speed electrical machines, where…

Closed-Loop Analysis and Control of Cavity Shear Layer Oscillations.

This paper focuses on the closed-loop control of an incompressible flow past an open cavity. We propose a delayed feedback controller to suppress the self-sustained oscillations of the shear layer. The control law shows robustness to changes in flow…

Reproducing topography and roughness of osteoconductive materials in a microfluidic device for bone tissue engineering

This paper is in the framework of tissue engineering, based on bioreactor for cultivating bone-forming cells on biomimetic materials, such as coral scaffold. In order to optimize such process and to have a better understanding of biophysical and…

Energy Recovery Power Supply for Piezoelectric Actuator

Piezoelectric actuators are used successfully to enable locomotion of micro-robot such as micro air vehicle with flapping wings. However, the use of piezoelectric actuators presents a major challenge for power electronic design: the input…

Extended braking stiffness estimation based on a switched observer, with an application to wheel-acceleration control

In the context of hybrid anti-lock brake systems (ABS), a closed-loop wheel-acceleration controller based on the observation of the extended braking stiffness (XBS) is provided. Its objective is to improve the system's robustness with respect to…
