... re-engineering may provide a step towards efficient multi-scale network re-engineering workflows. In this paper we will describe novel mathematical approaches which allow the efficient re-engineering of network ... of stimuli and inhibitors from k = 1, ,m, then all coefficients of F up to interactions of order m can be estimated from the data. In each experiment coefficients will be ‘active’ (...

... fixed-point numeric formats, for all data channels in the system. This transition necessitates careful consideration of the ranges and precision required for each channel, the overflow and quantisation ... feature of this approach is the use of probabilistic bounds on the distribution of values of a data channel. The authors introduce the probability factor λ, which in a nor- mal hard upper-b...

... equalized by designing a suitable equalizer. For mDECT-SB, the distor- tion caused in the subbands towards the edges of the channel selection filter will be higher and the equalizer performance will ... 12.8kbps channel is supported by mDECT-SB with a TDMA effi- ciency of 70%. This is a little higher than the efficiency of conventional GFSK-based DECT for a 32 kbps channel. At 12.8 kbps,...
