In this paper, we investigate the problem of link-level resource provisioning in multi-radio multi-channel (MRMC) wireless networks. A robust channel assignment algorithm is proposed that explicitly takes into consideration link-level demands. Our solution approach utilizes the dual decomposition[11] and Gibbs sampler techniques, which effectively incorporate the channel allocation (combinatori...

This is a tutorial article presenting comparison between single input single output and multi input multi output wireless channel. We have compared Shannon ergodic capacity of SISO link and its different realizations with MIMO wireless channel. It is shown that wireless channel capacity increases linearly with the increase of multiple antennas both at transmitter and receiver. MIMO wireless lin...

Background: Anatomical and histological studies of the spinal cord have always garnered anatomists’ attention because of their high importance in various fields of veterinary medicine, zoology and behavioral science. OBJECTIVES: This work was conducted to understand the detailed histomorphometric aspects of the spinal cord of Indian gray mongoose (Herpestes edwardsii). METHODS: Six adult Indian...

A four-channel wavelength multiplexer/demultiplexer for sparse wavelength division multiplexing was demonstrated using cascaded three-dimensional ~3D! vertical couplers. 17 nm channel spacing with crosstalk less than 15 dB was achieved. Strong coupled vertical couplers were fabricated using wafer bonding to invert a conventionally processed epitaxial layer and bond to a new host substrate. This...
