Capacity of Binary State Symmetric Channel with and without feedback and transmission cost
(Institute of Electrical and Electronics Engineers Inc., 2015)We consider a unit memory channel, called Binary State Symmetric Channel (BSSC), in which the channel state is the modulo2 addition of the current channel input and the previous channel output. We derive closed form ...

Carrier relaxation dynamics in SnxNy nanowires grown by chemical vapor deposition
(2009)Carrier relaxation dynamics in tin nitride (SnxNy) nanowires have been investigated using femtosecond transient absorption spectroscopy. The nanowires were grown directly on quartz using chemical vapor deposition and had ...

High yield-low temperature growth of indium sulphide nanowires via chemical vapor deposition
(2010)Indium sulphide nanowires (NWs) have been grown on Si via the reaction of In and InCl3 with H2S using chemical vapor deposition at temperatures as low as 250 °C. We find that the growth of InxSy NWs via the direct reaction ...

High-resolution quadrature photopyroelectric spectroscopy of a-Si:H thin films deposited on silicon wafers
(1995)The recently developed photothermal technique of quadrature photopyroelectric spectroscopy (Q-PPES) has been applied to measurements of amorphous Si thin films deposited on crystalline Si substrates. Direct, meaningful ...

Nonanticipative transmission for sources and channels with memory
(Institute of Electrical and Electronics Engineers Inc., 2015)In this paper we analyze nonanticipative (delayless) transmission of source symbols with memory over channels with memory (with and without feedback). We employ duality of source, channel pairs with respect to distortion ...

Phase shifted Bragg gratings formed in optical fibres by post-fabrication thermal processing
(1996)Fibre Bragg gratings have been post-fabrication processed using localised heat treatment, with significant changes to their transmission and reflection characteristics being observed. Experimental results of the spectral ...

The Radiosity Diffusion model in 3D
(2001)We present the Radiosity-Diffusion model in three dimensions (3D), as an extension to previous work in 2D. It is a method for handling non-scattering spaces in optically participating media. We present the extension of the ...

Reversible hydrogels from amphiphilic polyelectrolyte model multiblock copolymers: The importance of macromolecular topology
(2010)The association ability of model amphiphilic polyelectrolytes with multi-block architecture, i.e. ABA, BABAB, ABABABA and BABABABAB (A hydrophobic, B polyelectrolyte block) was studied in aqueous media. The gelation ...

Study of optical fiber structures using atomic force microscopy and scanning near-field optical microscopy
(1996)Atomic force microscopy (AFM) and scanning near-field optical microscopy (SNOM) were used to study optical fiber structures. The refractive index profile of fiber was disclosed by surface topography of etched fiber endface ...

Ultrafast time-resolved spectroscopy of ZnSe nanowires: Carrier dynamics of defect-related states
(2009)In recent years, ZnSe nanowires have been widely investigated for their potential applications in optoelectronics. A typical room temperature photoluminescence spectrum of ZnSe nanowires grown by vapor-liquid-solid growth ...
