Pulmonary tuberculosis (PTB) remains a worldwide public health problem. Diagnostic algorithms to identify the best combination of diagnostic tests for PTB in each setting are needed for resource optimization. We developed one artificial neural network model for classification (multilayer perceptron—MLP) and another risk group assignment (self-organizing(More)
—This work reports on the development of a multi-channel analyzer (MCA) circuit for use in radiation detection. The MCA is based on a fast analog-to-digital converter (ADC) plus a digital circuitry programmed on a complex programmable logic device (CPLD). The ADC digitizes the input signals with high accuracy and low nonlinearity while the CPLD performs the(More)
The estimation of the Direction Of Arrival (DOA) of signals in a set of sensors has applications in different engineering areas. In submarine acoustics, the DOA estimates for a passive sonar system has the objective to inform the presence of a target (ship) in one determined direction (bearing). In accordance to the bearing's resolution, space interference(More)
An online particle discrimination system is proposed for the ATLAS particle detector, which will be placed at one of the collision points of LHC, the next generation particle collider experiment. segmented independent component analysis (SICA) is applied over a highly segmented calorimeter (energy measurement system) in order to cope with the different(More)
