Simultaneous wireless information and power transfer (SWIPT) is an appealing research area because both information and energy can be delivered to wireless devices simultaneously. In this paper, we propose a diplexer-based receiver architecture that can utilizes both the doubling frequency and baseband signals after the mixer. The baseband signals are used for information decoding and the doubl...

I will discuss index theory in the context of Poincare-Einstein manifolds of AdS/CFT fame. Complications arise because Dirac operators are not Fredholm and the Atiyah-Singer integrands are not integrable. In some cases, renormalization allows us to circumvent these difficulties.

A two-dimensional photonic crystal diplexer integrated with a waveguide coupler is proposed. The design is computer generated through an inverse design process, limited within an area measuring 5 mumx5 mum. The best working device was designed for the optical communication wavelengths, 1.50 mum and 1.55 mum, i.e. a channel spacing of 50 nm. The device exhibits crosstalks suppressed below 40dB a...

the wiener index w(g) of a connected graph g is defined as the sum of the distances betweenall unordered pairs of vertices of g. the eccentricity of a vertex v in g is the distance to avertex farthest from v. in this paper we obtain the wiener index of a graph in terms ofeccentricities. further we extend these results to the self-centered graphs.

Existing file searching tools do not have the performance or accuracy that search engines have. This is especially a problem in large-scale distributed file systems, where better-performing file searching tools are much needed for enterprise-level systems. Search engines use inverted indices to store terms and other metadata. Although some desktop file searching tools use indices to store file ...

In this paper a novel design of microstrip diplexer and triplexer using open loop resonators is presented. The proposed diplexer if formed by two band-pass filters for the Industrial Scientific Medical (ISM) applications at 5.8 GHz and the WIMAX applications (IEEE 802.16 WiMAX at 3.17 GHz to 4.2 GHz bands). The microstrip triplexer is designed for the Digital Communication System (DCS) at 1.8 G...
