A Cúk converter operating in discontinuous capacitor voltage mode (DCVM) is an inherent power factor correction converter. A reduced-order switch-network model of a Cúk converter in DCVM is developed, which is valid for both dc-dc and ac-dc applications. The model can be used for controller analysis and design. Moreover, a fast dynamic(More)
The effect of the fluorine content and nano-structure of fluoridated hydroxyapatite (FHA) on human osteoblast-like (HO) cell behavior were investigated. FHA nanopowders and bulk nanostructured FHA, produced via mechanical alloying and two-step sintering, respectively, were used. The cytotoxicity of FHA nanopowders was assessed by MTT. Cell attachment to the(More)
Sensor networks are large scale networks of low power devices that collaborate in order to perform a given task. The sensors are limited in battery energy, capacity and computational power. In recent years, researcher have proposed several protocols for such sensor networks assuming that all sensors belong the same authority. In this paper, we introduce the(More)
