Characteristics of the elderly in high - resolution computed tomography lung densitometry [PDF]
, 2004 To determine the characteristics of the elderly in high - resolution computed tomography (HRCT) lung densitometry, mean lung density (MLD) and relative area of the lungs showing attenuation values less than -950 HU (RA(950)) on HRCT were evaluated in ...

Energy Harvesting Noncoherent Cooperative Communications
, 2015 This paper investigates simultaneous wireless information and power transfer (SWIPT) in energy harvesting (EH) relay systems. Unlike existing SWIPT schemes requiring the channel state information (CSI) for coherent information delivery, we propose a ...

Novel multifunctional decoder for MLD codes
Electronics Letters, 1990 A multifunctional decoder based on the decoding algorithm of linear majority-logic-decodable (MLD) codes over GF(q) used for both error correction and detection is presented. Ascheme of L-step majority-logic decoding using this algorithm is also proposed.

Maximum-likelihood decoding of Reed-Solomon Codes is NP-hard
, 2004 Maximum-likelihood decoding is one of the central algorithmic problems in coding theory. It has been known for over 25 years that maximum-likelihood decoding of general linear codes is NP-hard.

Frequency dependence of the MLD in forward masking [PDF]
The Journal of the Acoustical Society of America, 1982 Detectability for the binaural conditions NOSII and NOSM was compared to that of a reference mortaural system condition (either NOSO or NMSM) in a forward masking paradigm. When signal frequency was varied, the pattern of MLDs obtained was similar to that observed in simultaneous masking: For both the NOSO and NOSM conditions the largest MLDs were ...

Interior Point Decoding for Linear Vector Channels
, 2008 In this paper, a novel decoding algorithm for low-density parity-check (LDPC) codes based on convex optimization is presented. The decoding algorithm, called interior point decoding, is designed for linear vector channels.

Noncoherent Relaying in Energy Harvesting Communication Systems
, 2015 In energy harvesting (EH) relay networks, the coherent communication requires accurate estima- tion/tracking of the instantaneous channel state information (CSI) which consumes extra power.

Jet schemes, log discrepancies and Inversion of Adjunction
, 2002 We use the theory of motivic integration for singular spaces to give a characterization of minimal log discrepencies in terms of the codimension of certain subsets of spaces of arcs.
