Identification and identity in the development of historical memory: the Kingdom of Murcia and the Middle Ages
La realidad histórica de una actual Comunidad Autónoma de la Región de Murcia hunde sus raíces en plena Edad Media. Si bien esto es común a la inmensa mayoría de regiones europeas, lo particular de este territorio es el modo en que la memoria que aquella época dejó en sus pobladores hasta el día de hoy ha reflejado una concreta manera de entender su propia existencia como institución regional, con su cultura específica fruto de ese complejo devenir histórico.The historical reality of an actual region of Murcia has its roots in the Middle Ages. While this is common to the vast majority of European regions, particularly in this area is the way that the memory that time left its inhabitants to this day reflected a concrete way to understand your own existence as a regional institution with its specific culture result of this complex historical process
Poderes locales, dominio territorial y control central en la Castilla meridional (ss. XIII-XVI): gobernar fronteras
Controlling such territories as were most remote from the centres of power has always been one of the objectives of those who sought to set up a political organization based on a centralized system of power. The example of Castile and the lands bordering the Nasrid sultanate of Granada during the Late Middle Age affords a model for analyzing this phenomenon. The process of monarchical rule over outlying territories near an asymmetric boundary as was the Castilian-Nasrid frontier line additionally involved two intermediate factors: the landed gentry and the local power groups. These helped define the slow but inexorable path to the political praxis of a powerful Crown and gave rise to procedures that would later be used, already in the Modem Era, to incorporate the vast American dominions.El control de los territorios más alejados de los núcleos de poder siempre ha sido uno de los objetivos de quienes pretendían configurar un organigrama político de autoridad y potestad centralista. El ejemplo de Castilla y sus tierras fronterizas con el sultanato nazarí de Granada durante los siglos bajomedievales se erige como un modelo de análisis para este fenómeno. El proceso de dominio monárquico sobre territorios periféricos, en una frontera asimétrica como lo era la castellano-nazarí, contó además con dos factores intermedios, nobleza territorial y grupos de poder local, que contribuyeron a definir el lento pero inexorable camino hacia la praxis política de una Corona poderosa, método que sirvió para incorporar los extensos dominios americanos, ya en época moderna
The Need for Unification and Harmonization in a Maritime Licensing Standard for Recreational Craft
The objective of this document is to make clear the importance of simplifying the transit of pleasure boats and their skippers safely in the European territory with the foreseeable improvement of the functioning of the internal market. In many European countries recreational skippers are required to have specific training and experience in order to demonstrate their maritime competence. These licenses for navigation allow a recreational vessel to be skippered in each national territory. One of the main objectives of these qualifications is to reduce the number of accidents in recreational boating. Generally speaking, in the European Union, as regards the requirements for the management of pleasure craft, both private and professional, the requirements are very different depending on the member state
Deep Neural Networks for the Recognition and Classification of Heart Murmurs Using Neuromorphic Auditory Sensors
Auscultation is one of the most used techniques for
detecting cardiovascular diseases, which is one of the main causes
of death in the world. Heart murmurs are the most common abnormal
finding when a patient visits the physician for auscultation.
These heart sounds can either be innocent, which are harmless, or
abnormal, which may be a sign of a more serious heart condition.
However, the accuracy rate of primary care physicians and expert
cardiologists when auscultating is not good enough to avoid most
of both type-I (healthy patients are sent for echocardiogram) and
type-II (pathological patients are sent home without medication or
treatment) errors made. In this paper, the authors present a novel
convolutional neural network based tool for classifying between
healthy people and pathological patients using a neuromorphic
auditory sensor for FPGA that is able to decompose the audio into
frequency bands in real time. For this purpose, different networks
have been trained with the heart murmur information contained in
heart sound recordings obtained from nine different heart sound
databases sourced from multiple research groups. These samples
are segmented and preprocessed using the neuromorphic auditory
sensor to decompose their audio information into frequency
bands and, after that, sonogram images with the same size are
generated. These images have been used to train and test different
convolutional neural network architectures. The best results
have been obtained with a modified version of the AlexNet model,
achieving 97% accuracy (specificity: 95.12%, sensitivity: 93.20%,
PhysioNet/CinC Challenge 2016 score: 0.9416). This tool could aid
cardiologists and primary care physicians in the auscultation process,
improving the decision making task and reducing type-I and
type-II errors.Ministerio de Economía y Competitividad TEC2016-77785-
NAVIS: Neuromorphic Auditory VISualizer Tool
This software presents diverse utilities to perform the first post-processing layer taking the neuromorphic auditory sensors (NAS) information. The used NAS implements in FPGA a cascade filters architecture, imitating the behavior of the basilar membrane and inner hair cells and working with the sound information decomposed into its frequency components as spike streams. The well-known neuromorphic hardware interface Address-Event-Representation (AER) is used to propagate auditory information out of the NAS, emulating the auditory vestibular nerve. Using the information packetized into aedat files, which are generated through the jAER software plus an AER to USB computer interface, NAVIS implements a set of graphs that allows to represent the auditory information as cochleograms, histograms, sonograms, etc. It can also split the auditory information into different sets depending on the activity level of the spike streams. The main contribution of this software tool is that it allows complex audio post-processing treatments and representations, which is a novelty for spike-based systems in the neuromorphic community and it will help neuromorphic engineers to build sets for training spiking neural networks (SNN).Ministerio de Economía y Competitividad TEC2012-37868-C04-0
"Han quedado tan amedrentados…": The Indian rebellion of 1792-93 in the plains of Valdivia and the treatment of non-combatant during the Spanish repression
En 1792, confusos incidentes vinculados con la actuación de los misioneros franciscanos entre los indios huilliche de los llanos de Valdivia (Chile), derivaron en una venganza y rebelión nativa. Los hechos violentos que se sucedieron, incluyendo la muerte de un fraile, En 1792, confusos incidentes vinculados con la actuación de los misioneros franciscanos entre los indios huilliche de los llanos de Valdivia (Chile), derivaron en una venganza y rebelión nativa. Los hechos violentos que se sucedieron, incluyendo la muerte de un fraile, dieron inicio a una rigurosa represión por parte del ejército español cuyo seguimiento, facilitado por las abundantes fuentes que lo documentan, abre el acceso a un escrutinio de las formas de castigar a los insumisos. La actuación del cuerpo armado y de su comandante, así como las instrucciones que recibió de sus superiores, permiten examinar las prácticas militares hispano-criollas a la luz tanto de las normas entonces vigentes acerca de la manera aceptable de hacer la guerra, como de su accionar bélico real sobre el campo, respaldado por una larga tradición en las fronteras de la monarquía hispánica.In 1792, confuse incidents linked with the performance of Franciscan missionaries among the huilliche Indians in the plains near Valdivia (Chile), led to native revenge and rebellion. The violent facts which came along, including the death of a Friar, triggered a rigorous repression by the Spanish army, the following of which (facilitated by the abundant sources available) opens access to a scrutiny on the ways of punishing the resisting. The performance of the armed corps and its commander, as well as the instructions he received from his superiors, allow examination of Spanish military practices under de light of the norms then in force regarding not only the acceptable way of making war, but also their actual warfare action on the field, backed by a long tradition in the frontiers of the Hispanic monarchy.Fil: Alioto, Sebastián Leandro.
