This paper reports on the design and experimental verifications of a passive step-up rectifier for MEMS piezoelectric energy scavengers. The purpose of the proposed circuit is to improve system startup for vibration micro-generators without the need of an ...
The sun is the biggest known source of energy in our solar system. We feel its strength when it gets hot during the the day and we notice its absence during the night when we feel cold. So as to be less dependent on the sun as an energy source, we implemen ...
Today, energy saving is one of the main objectives for engineers. In the case of mobile applications, energy can be saved by two different ways. First, decreasing the total masse of the system, and second, increasing the efficiency of the overall system. T ...
We present an a priori error analysis of a practical energy based atomistic/continuum coupling method (A. V. Shapeev, Multiscale Model. Simul., 9(3): 905-932, 2011) in two dimensions, for finite-range pair-potential interactions, in the presence of vacancy ...
Contactless energy transfer is very promising in terms of property and handling. In clean rooms contactless energy transfer allows to build moving robots without any bending cable that emits particles with every movement. We want to test one possibility to ...
In industrialized countries, more than two-thirds of the energy is consumed in urban areas. Hence, energy sobriety calls for special attention to urban planning, especially regarding energy aspects. ...
We correct typos in eq. (2.41) and (2.42) of ref. [1]. This has several repercussions for the equations of section 2.3, but none for the subsequent sections or for the conclusions of the paper ...
Since its emergence as a field, optofluidics has developed unique tools and techniques for enabling the simultaneous delivery of light and fluids with microscopic precision. In this Review, we describe the possibilities for applying these same capabilities ...
HiRadMat (High Irradiation to Materials) is a new facility under construction at CERN designed to provide highintensity pulsed beams to an irradiation area where material samples as well as accelerator component assemblies can be tested. The facility uses ...
This paper presents an approach to design a contactless energy-transfer system to supply desktop computer peripherals. Energy is transferred using coreless transformers from an array of primary coils (placed on a table) to one or several secondary coils (p ...
