The 'Red Terror' and the Spanish Civil War
This study challenges the common view that extrajudicial executions in Republican Spain in July 1936 were the work of criminal or anarchist 'uncontrollables'.
XV International Scientific Conference “INTERAGROMASH 2022”
The book contains proceedings of the XV International Scientific Conference INTERAGROMASH 2022, Rostov-on-Don, Russia. This conference is dedicated to the innovations in the field of precision agriculture, robotics and machines, as well as agriculture biotechnologies and soil management. It is a collection of original and fundamental research in such areas as follows: unmanned aerial systems, satellite-based applications, proximal and remote sensing of soil and crop, positioning systems, geostatistics, mapping and spatial data analysis, robotics, and automation. Potential and prospects for the use of hydrogen in agriculture, for example, in high-performance tractors with hybrid electric tran...
Adaptive Implementation of Discrete Event Control Systems Based on Sequential Function Charts
In this work we have developed an adaptive implementation of Discrete Event Control Systems, the Execution Time Controller, which allows choosing in real time the most suitable algorithm to execute a Sequential Function Chart. The main function of the ETC will be to determine which algorithm executes a SFC the fastest. The proposed technique is analyzed with the two most important algorithms (from the point of view of performance): the enabled transitions and the static representing places. However, the ETC can work with any SFC implementation algorithm. The ETC executes the chosen algorithm and estimates the execution time of other nonexecuted algorithms, deciding the best one in line. The ...

Development of Customized Distribution Automation System (DAS) for Secure Fault Isolation in Low Voltage Distribution System
In this paper, we have proposed a control architecture and a development environment based on Petri Nets, SFCs and the Java language. The architecture is related with the coordination and the local control layers of flexible manufacturing systems. A centralized approach permits the easy development and debugging of new control techniques. One of the mains contributions of this paper is that the proposed architecture allows the verification of the real time constraints of control systems and the use of formal tools as PNs and SFCs.
Multichannel Bioimpedance Meter for Cardiovascular Time Interval Analysis
Impedance plethysmography (IPG) is common noninvasive technology often used to monitor and quantify physiological phenomena that involve volume changes. Recently, a new IPG signal has been proposed that is measured by using only surface contacts with the limbs. This signal carries useful information about the cardiovascular system that otherwise could be obtained only by manual methods that require a skilled medical or nurse practitioner and are lengthy to apply hence unsuitable for e-health scenarios. This new signal is protected by several patents owned by UPC as it could be a breakthrough in cardiovascular measurements. The work to be performed involves the conception, implementation and verifications of a three-channel system able to simultaneous measure three IPG signal in the same subject, which is performant enough to assess changes in time intervals measured between singulars features of these signals and those of other cardiovascular signals. This requires a low-noise design robust to interference preferably based on a low-power microcontroller.
