Likelihood-Ratio-Based Biometric Verification [PDF]
, 2004 The paper presents results on optimal similarity measures for biometric verification based on fixed-length feature vectors. First, we show that the verification of a single user is equivalent to the detection problem, which implies that, for single-user ...

Genetic Algorithm Assisted Error Probability Optimisation for Beamforming
, 2004 A novel Genetic Algorithm (GA) assisted direct error probability optimisation technique is proposed for adaptive beamforming, which reduces the achievable error probability by nearly two orders of magnitude at a signal-to-noise ratio of 10dB in the ...

Ratio-based multi-level resistive memory cells
Scientific Reports, 2021 Ratio-based encoding has recently been proposed for single-level resistive memory cells, in which the resistance ratio of a pair of resistance-switching devices, rather than the resistance of a single device (i.e.

Comparison of equalisation strategies for multi-carrier CDMA [PDF]
, 2003 This paper focuses on the bit error rate (BER) performance of equalisation strategies for a downlink MC-CDMA based system. Simulation results utilising maximal ratio combining (MRC), orthogonal restoring combining (ORC), equal gain combining (EGC) and ...

Bias caused by sampling error in meta-analysis with small sample sizes. [PDF]
PLoS ONE, 2018 BACKGROUND:Meta-analyses frequently include studies with small sample sizes. Researchers usually fail to account for sampling error in the reported within-study variances; they model the observed study-specific effect sizes with the within-study ...

Reliable random error estimation in the measurement of line-strength indices [PDF]
, 1997 We present a new set of accurate formulae for the computation of random errors in the measurement of atomic and molecular indices. The new expressions are in excellent agreement with numerical simulations.
