Polymer-ceramic composites have gained considerable attention in flexible electronic devices due to their uncommon features such as high dielectric constant, low conductivity, and good mechanical flexibility. The electrical responses of various components (ceramic grain & boundary, polymer chains, interface) need be elucidated rationally design high-performance polymer-ceramic composites. This ...

BACKGROUND This study describes the use of adenosine during ablation procedures to allow conduction through adenosine-dependent accessory pathways (APs), which are inactive at the time of the procedure. The technique allows for successful mapping and ablation of these pathways. METHODS Retrospective review of all patients undergoing AP ablation from 1998 to 2008 to identify patients with abse...

This paper presents the detailed mathematical modeling of Z-source dc-dc converter (ZSC) in continuous conduction mode. Transfer function of ZSC is derived based on mathematical modeling with state space averaging method. This paper has been focused on dynamic modeling of open loop transfer function of ZSC along with design of closed loop controller. MATLAB based simulation results are presente...
