The current trend for multipurpose rooms requires enhanced acoustic treatments capable to meet ever more demanding specifications in terms of performance, compactness and versatility. The reason is the variety of activities to be hosted and the correspondi ...
In the past two decades, the fact that “small is different” has been established for a wide variety of phenomena, including electrical, optical, magnetic, and mechanical behavior of materials. However, one largely untapped but potentially very important ar ...
This paper presents an equivalent electrical circuit for one dimensional substrate minority carriers spice simulation. The electrical circuit parameters are extracted from substrate meshing applying the finite difference method. This model is derived from ...
Piezoelectric actuators (PEAs) have been widely used in nano-positioning applications for their high resolution of displacement. However, hysteresis, which is an inherent property of ferroelectric PEAs has been shown to significantly degrade the system per ...
This paper presents a novel high-frequency tunable band-stop filter concept based on a single MEMS capacitive shunt device which uses meander arm anchoring inductors and with a total size of 300 × 600 μm. Tuning ranges of the central frequency in the order ...
A simple phenomenological model with two coupled structural and ferroelectric order parameters is under consideration. The small-signal dielectric response, dielectric response to a strong electric field (hysteresis phenomena included), and the phase diagr ...
It is important for building designers to be able to judge if a space is likely to overheat, whether to determine if HVAC plant is required or to design this out by passive means. To this end several overheating risk criteria have recently been published. ...
The dc transformers based on an LLC converter operated in open loop near resonant frequency have several crucial advantages compared to other topologies. These advantages are the stiff voltage ratio with a natural power flow, the dc grid isolation via medi ...
SystemC-AMS currently offers modelling formalisms with specialised solvers mainly focussing on the electrical domain. There is a need to improve its modelling capabilities concerning conservative continuous time systems involving the interaction of several ...
