OpenStack, a cloud operating system which is open source, is enable to build public and private clouds. OpenStack rely on virtualization techniques offered by different vendors through their virtualization software. VMware, Citrix and Microsoft are primary vendors for such hypervisors. There are several Open Source hypervisors like KVM, Oracle's Virtual box also offers virtualization techniques that...
This paper presents the design of a novel miniaturized dual-band band pass filter based on the composite right/left-handed (CRLH) metamaterial structure. In detail, sub wavelength resonators are realized through the zeroth order resonance (ZOR), and inverter structures are proposed to control the coupling between neighboring ZOR resonators. The Technique is validated by EM Predictions using IE3D.
Wireless Optical communication [WOC] is improved using relay assisted transmission which exploits multiple shorter hops that gives a better performance gain. Relay assisted transmission is used as a mitigation tool in combating atmospheric turbulence occurring in the communication channels. The prime aim is to minimize the outage probability and optimize relay locations for parallel and serial FSO...
Wind energy conversion systems are becoming popular in the research areas of renewable energy resources. The commonly used generators with wind energy conversion system (WECS) are Squirrel Cage Induction Generator (SCIG), Doubly Fed Induction Generator (DFIG), Wound Field Synchronous Generator (WFSG) and Permanent Magnet Synchronous Generator (PMSG). Recently PMSG is gaining popularity as it has many...
Since the US Federal Communications Commission (FCC) released the unlicensed use of the ultra-wideband (3.1-10.6 GHz) spectrum for indoor and hand-held systems in Feb-2002[1]. Recently, the development of new UWB filters has increased via different methods and structures [2]??[5]. In [2] an initial UWB filter is presented by mounting a microstrip line in a lossy composite substrate to attenuate the...
