The objective of this paper is to show that under some circumstances, the sign of a sampled sinusoid sequences, briefly 􀀀, is optimal to provide maximum energy transfer to linear resonators in the context of discrete-time ...

The aim of this paper is to apply an approach that will allow us to consider different mechanical modes of a MEMS cantilever in the form of separate mass-spring-damper equations with the appropriate form of an external ...

Direct numerical simulation and large-eddy simulation have been performed for a heated sphere at Reynolds numbers of $Re=1000$ and $Re=10^4$, respectively. The Prandtl number for both simulations has been $Pr=0.7$. ...

The objective of this paper is to analyze the dynamics of heat flow in thermal structures working under constant temperature operation. This analysis is made using the tools of sliding mode controllers. The theory is ...

There exist industrial applications where an accurate estimation of a light source position is needed. That is the case for a heliostat, a device that projects sunlight upon a focus hundreds of meters distant. In this paper ...

This paper describes the design and optimization of a hot-wire air flowmeter. A low-cost design of the packaging allows good thermal contact with the airflow, as well as good thermal isolation between the hot and cold ...

This paper presents a characterization method based on diffusive representation for a class of linear or nonlinear time-varying diffusive systems. The system variation with time may come as a result of the own actuation ...
