We consider a multi-user impulse radio UWB physical layer in a multipath environment. We propose a fast and efficient method to compute the conditional bit error rate (BER), given some realizations of the channels from source/interferer to destination, and ...
The invention concerns an assembly comprising: (a) means for determining the intensity of a plurality of electromagnetic signals, (b) a correlator for correlating or autocorrelating said signals, (c) means for continuously calculating the variance and/or t ...
The finite sample performance of a nearest neighbor classifier is analyzed for a two-class pattern recognition problem. An exact integral expression is derived for the m-sample risk R(m) given that a reference m-sample of labeled points is available to the ...
This paper presents a general method for incorporating prior knowledge into kernel methods such as Support Vector Machines. It applies when the prior knowledge can be formalized by the description of an object around each sample of the training set, assumi ...
Absorption and photoluminescence excitation (PLE) spectra were recorded for colloidal CdSe quantum dots of different sizes. No significant deviation between the PLE and the absorption spectra, provided appropriate corrections and sample treatment are made ...
Solute transport in natural formations at the regional scale is influenced by several scales of heterogeneity which correspond to the presence of several geological units called facies. As customarily assumed in stochastic theories, inside the facies the t ...
We report a precise determination of the Z0-B̄0 mixing parameter Δmd based on the time evolution of same-sign and opposite-sign dilepton yields in Y(45) decays. Data were collected with the Belle detector at KEKB. Using data samples of 29.4 fb-1 recorded a ...
