(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 ...

(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 ...

(Optical Society of America, 2012-02)The statistical properties of speckles in paraxial optical systems depend on the system parameters. In particular, the speckle orientation and the lateral dependence (x and y) of the longitudinal speckle size can vary ...

(Optical Society of America, 2012-03)In [1,2] an error (by a factor of 1000) in the diffusion rate of monomer in a photopolymer material used by the authors of [3], is presented. In [3] no errors are identified in our analysis and our physical evidence is not ...

(Taylor & Francis, 2012-09)Growing worldwide interest in the exploitation of geothermal energy resources has led to a scenario where the technology routinely forms part of building-scale renewable energy feasibility studies. A thorough understanding ...

(Taylor & Francis, 2012-04-13)Ireland is one of a very small number of countries in the world which do not charge for domestic drinking water supply. Recent developments have indicated that the reintroduction of domestic charges in Ireland is being ...

Oil refinery wastewater treatment using physicochemical, Fenton and Photo-Fenton oxidation processes (Taylor & Francis, 2012-02-09)The objective of this study was to investigate the application of advanced oxidation processes (AOPs) to the treatment of wastewaters contaminated with hydrocarbon oil. Three different oil-contaminated wastewaters were ...

(Elsevier, 2012-05)A companion paper considers travelling and standing waves in cascaded, lumped, mass-spring systems, controlled by two boundary actuators, one at each end, when the system is uniform. It first proposes definitions of waves ...
