High Availability Automation Networks: PRP and HSR Ring Implementations
(IEEE, 2012-05)
The work developed has as basis the networks/protocols described in the standard IEC 62439-3 Industrial automation networks - High availability automation networks: PRP and HSR. The similarities of both networks and a ...
Memory Requirements Analysis for PRP and HSR Hardware Implementations on FPGAs
(IEEE, 2014-01-02)
The IEC62439-3 defines two ways to obtain a high availability automation network: Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR). In order to do that, those methods include different ...
Multi-GGS-groups have the congruence subgroup property
(Cambridge University Press, 2019-02-21)
We generalize the result about the congruence subgroup property for GGS-groups to the family of multi-GGS-groups; that is, all multi-GGS-groups except the one defined by the constant vector have the congruence subgroup ...
Pueblos libres y pueblos serviles en la historiografía y la literatura decimonónicas sobre el País Vasco
(Presses universitaires de Franche-Comté, 2018)
Los historiadores grecorromanos recogen mayoritariamente un discurso favorable al imperialismo romano, pero también visiones más críticas de la conquista, bien mediante la idealización
del bárbaro, bien mediante discursos ...
Impact of a resistive superconductive fault current limiter in a multi-terminal HVDC grid
(IEEE, 2018-06-11)
The relevance of multi-terminal HVDC grids is
expected to increase in next years. However, there are still several
technical, economical and legal limitations that interfere with the
construction of those multi-terminal ...

(IATED, 2019)
[ES] El texto aborda la necesidad de que exista una comunicación directa entre la Enseñanza Secundaria y la Universidad para diseñar un recorrido coherente que redunde en la calidad de la enseñanza. Analiza diversas ...
Handwriting: Important issues through Basque/Spanish materials
(2018-07-26)
In this age of new technologies, handwriting is still important. There is strong evidence showing that if children are slow as they form letters then language processing may be affected at higher levels (e.g., forming ...
Type Testing of a Highly Accurate Illuminance Flickermeter
(IEEE, 2012)
The standard IEC 61000-4-15 establishes the design specifications to measure the annoyance produced by flicker. This instrument is based on the working principles and the response to input voltage variations of an incandescent ...
PRP and HSR Version 1 (IEC 62439-3 Ed.2), Improvements and a Prototype Implementation
(IEEE, 2013-11)
The IEC62439-3: Industrial communication networks - High availability automation networks - Part 3: Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR), defines two protocols which provides ...
OLYMPUS: An intelligent interactive learning platform for procedural tasks
(ScitePress, 2012)
Providing Interactive Systems with educational capabilities is essential in order to achieve real effectiveness in simulation based training. However, the development cost of adding intelligence to those systems is huge. ...
