GSM voice evolution using orthogonal subchannels
IEEE Communications Magazine, 2012The explosive growth of mobile communications, and the overly crowded and expensive spectrum have pushed both system engineers and operators to make their systems as spectrally efficient as possible in order to accommodate the increasing traffic demand. This article is a tutorial introduction to the orthogonal subchannel (OSC) technique.

A Utility Perspective on Subchannel Analysis
Nuclear Technology, 1995Utility nuclear engineering organizations are among the primary end users of subchannel analysis technology. Typically there is only a limited involvement by utility staff in the actual development of subchannel software other than the addition of user convenience features such as editing routines and automated execution of multiple cases.

Subchannel allocation for the OFDMA-based femtocell system
Computer Networks, 2013In femtocell networks, due to their small cell size, we can achieve higher spatial diversity from the channel reuse between multiple femtocells. In addition, if femtocells operate on OFDMA systems, each subchannel can be reused separately among femtocells, improving system efficiency more significantly.

The investigation of thermal hydraulic performance, either operating-steady-state or accident-transient conditions of nuclear reactor core, constitutes the topic of the present chapter. Standard nuclear thermal hydraulic equations and models, i.e., adopted for accident analysis in primary circuit and discussed in different chapters of the book, are ...

Development and validation of boron diffusion model in nuclear reactor core subchannel analysis
Annals of Nuclear Energy, 2019The diffusion characteristic of borated water in nuclear reactor core is important for the reactivity control during some possible reactivity transient scenarios. The non-uniform distributions of boron concentration increase the risk of reactor accidents
