Full Band Spectra Analysis of Gait Acceleration Signals for Peripheral Arterial Disease Patients
Frontiers in Physiology, 2018 Peripheral arterial disease (PAD) is an artherosclerotic occlusive disorder of distal arteries, which can give rise to the intermittent claudication (IC) phenomenon, i.e., limb pain and necessity to stop.

Accelerating the Detection of Spectral Bands by ANN-ED on a GPU
Computer and Information Science, 2015 Spectrum sensing is the most important technique used to implement cognitive radio; this approach allows opportunistic and dynamic allocation of spectral bands. Among the methods used for detection, there are Artificial Neural Networks (ANN) and Energy Detection (ED); those exploit the signals coming from a Fast Fourier Transformed block (FFT). In this

Stochastic Spectral and Conjugate Descent Methods
, 2018 The state-of-the-art methods for solving optimization problems in big dimensions are variants of randomized coordinate descent (RCD). In this paper we introduce a fundamentally new type of acceleration strategy for RCD based on the augmentation of the ...
