(IEEE, 2012-07-25)This paper introduces a new actuation scheme for implementing Pulsed Digital Oscillators (PDOs) for electrostatic MEMS resonators. In this scheme, the capacitance of the device is biased with a voltage and it is periodically ...

(2010-04)Accurate computational methods for predicting the electrostatic energies are of major importance for our understanding of protein energetics in general, for computer-aided drug design and in the design of novel biocatalysts ...

(IEEE, 2012-07)In this paper, we present numerical bifurcation analysis of an electrostatic vibration energy harvester operating in constant-charge mode and using the in-plane gap closing transducer. We show how the system can be represented ...

(IEEE, 2012)In this paper, we present a formal analysis and description of the steady-state behavior of an electrostatic vibration energy harvester operating in constant-charge mode and using different types of electromechanical ...

(American Institute of Physics, 2012-10-24)Based on the formal analysis of a resonant electrostatic vibration energy harvester operating in constant-charge mode with a gap-closing transducer, we show that the system displays universal behaviour patterns. In this ...

(2012-05)Wave-based control (WBC) of underactuated, flexible systems considers actuator motion as launching a mechanical wave into the flexible system which it then absorbs on its return to the actuator. The launching and absorbing ...

(American Institute of Physics, 2011)The collision of two laser generated plasma plumes can result, under appropriate conditions, in the formation of ‘stagnation layer’. The processes underlying this phenomenon are complex and time dependent. The majority of ...

(IEEE, 2010-05)In this paper, we study the possible output of the pulsed digital oscillator (PDO) with multiple resonant modes of the mechanical resonator in the feedback loop. PDOs are simple circuits that allow linear resonators to ...

(Elsevier, 2012-05)This paper shows how pure travelling waves in cascaded, lumped, uniform, mass-spring systems can be defined, established, and maintained, by controlling two boundary actuators, one at each end. In most cases the control ...
