A spiking neural network for real-time Spanish vowel phonemes recognition
This paper explores neuromorphic approach capabilities applied to real-time speech processing. A spiking
recognition neural network composed of three types of neurons is proposed. These neurons are based on an
integrative and fire model and are capable of recognizing auditory frequency patterns, such as vowel phonemes;
words are recognized as sequences of vowel phonemes. For demonstrating real-time operation, a complete
spiking recognition neural network has been described in VHDL for detecting certain Spanish words, and it has
been tested in a FPGA platform. This is a stand-alone and fully hardware system that allows to embed it in a
mobile system. To stimulate the network, a spiking digital-filter-based cochlea has been implemented in VHDL.
In the implementation, an Address Event Representation (AER) is used for transmitting information between
neurons.Ministerio de Economía y Competitividad TEC2012-37868-C04-02/0
Linear nested Artin approximation theorem for algebraic power series
We give a new and elementary proof of the nested Artin approximation Theorem
for linear equations with algebraic power series coefficients. Moreover, for
any Noetherian local subring of the ring of formal power series, we clarify the
relationship between this theorem and the problem of the com-mutation of two
operations for ideals: the operation of replacing an ideal by its completion
and the operation of replacing an ideal by one of its elimination ideals.Comment: Last version. To appear in Manuscripta Mat
On the computation of Bernstein–Sato ideals
In this paper we compare the approach of Brianc¸onand Maisonobe for computing Bernstein–Sato
ideals—based on computations in a Poincar´e–Birkhoff–Witt algebra—with the readily available
method of Oaku and Takayama. We show that it can deal with interesting examples that have proved
intractable so far.Ministerio de Ciencia y Tecnología BFM-2001-3164Junta de Andalucía FQM-33
Explicit Comparison Theorems for D -modules
We prove in an explicit way a duality formula between two A2-modules Mlog and Mflog
associated to a plane curve and we give an application of this duality to the comparison
between Mflog and the A2-module of rational functions along the curve. We treat the
analytic case as well
The Effectiveness of Advanced Practice Nurses with Respect to Complex Chronic Wounds in the Management of Venous Ulcers
This study aims to evaluate the effectiveness of advanced practice nurses with respect to complex chronic wounds (APN-CCWs) in the care of patients with venous ulcers. A multicentric, quasi-experimental pre-post study was conducted without a control group in the sanitary management areas where the APN-CCW program is being piloted. The intervention consisted of a mass training of clinical nurses from the participating districts on the proper management of injuries and the use of compression therapy. The data were collected through a specifically constructed questionnaire with questions regarding descriptive variables of injuries and their treatment. A total of 643 professionals responded (response rate of 89.1%), attending to a total population of 707,814 inhabitants. An increase in multilayer bandage use by 15.67%, an increase in elastic bandage use by 13.24%, and a significant decrease in the referral of patients to consultation with hospital specialists was achieved, from 21.08% to 12.34%. The number of patients referred to the APNs was 13.25%, which implied a resolution rate of 94.08% of their injuries. In conclusion, the coordination by the APN-CCWs in patients with venous ulcers was effective in improving the continuity of care, in the optimization of resources, and in their care role
Spike-based control monitoring and analysis with Address Event Representation
Neuromorphic engineering tries to mimic biological
information processing. Address-Event Representation (AER) is
a neuromorphic communication protocol for spiking neurons
between different chips. We present a new way to drive robotic
platforms using spiking neurons. We have simulated spiking
control models for DC motors, and developed a mobile robot
(Eddie) controlled only by spikes. We apply AER to the robot
control, monitoring and measuring the spike activity inside the
robot. The mobile robot is controlled by the AER-Robot tool,
and the AER information is sent to a PC using the
USBAERmini2 interface.Junta de Andalucía P06-TIC-01417Ministerio de Educación y Ciencia TEC2006-11730-C03-0
