Evaluating XMPP Communication in IEC 61499-based Distributed Energy Applications

The IEC 61499 reference model provides an international standard developed specifically for supporting the creation of distributed event-based automation systems. Functionality is abstracted into function blocks which can be coded graphically as well as via a text-based method. As one of the design goals was the ability to support distributed control applications, communication plays a central role in the IEC 61499 specification. In order to enable the deployment of functionality to distributed platforms, these platforms need to exchange data in a variety of protocols. IEC 61499 realizes the support of these protocols via "Service Interface Function Blocks" (SIFBs). In the context of smart grids and energy applications, IEC 61499 could play an important role, as these applications require coordinating several distributed control logics. Yet, the support of grid-related protocols is a pre-condition for a wide-spread utilization of IEC 61499. The eXtensible Messaging and Presence Protocol (XMPP) on the other hand is a well-established protocol for messaging, which has recently been adopted for smart grid communication. Thus, SIFBs for XMPP facilitate distributed control applications, which use XMPP for exchanging all control relevant data, being realized with the help of IEC 61499. This paper introduces the idea of integrating XMPP into SIFBs, demonstrates the prototypical implementation in an open source IEC 61499 platform and provides an evaluation of the feasibility of the result.Comment: 2016 IEEE 21st International Conference on Emerging Technologies and Factory Automation (ETFA

Open Information Architecture for Seamless Integration of Renewable Energy Sources

Electric power systems are currently confronted with a fundamental paradigm change related to its planning and operation, mainly caused by the massive integration of renewables. To allow higher penetration of them within existing grid infrastructures, the “smart grid” makes more efficient use of existing resources by integrating appropriate information technologies. Utilising the benefits of such smart grids, it is necessary to develop new automation architectures and control strategies, as well as corresponding information and communication solutions. This makes it possible to effectively use and manage a large amount of dispersed generators and to utilise their “smart” capabilities. The scalability and openness of automation systems currently used by energy utilities have to be improved significantly for handling a high amount of distributed generators. This will be needed to meet the challenges of missing common and open interfaces, as well as the large number of different protocols. In the work at hand, these shortcomings have been tackled by a conceptual solution for open and interoperable information exchange and engineering of automation applications. The approach is characterised by remote controllable services, a generic communication concept, and a formal application modelling method for distributed energy resource components. Additionally, the specification of an access management scheme for distributed energy resources, taking into account different user roles in the smart grid, allowed for a fine-grained distinction of access rights for use cases and actors. As a concrete result of this work, a generic and open communication underlay for smart grid components was developed, providing a flexible and adaptable infrastructure and supporting future smart grid requirements and roll-out. A proof-of-concept validation of the remote controllable service concept based on this infrastructure has been conducted in appropriate laboratory environments to confirm the main benefits of this approach

Austrian Lives

Writing biographies (life stories) for a long time had been a male hegemonic project-writing the lives of great (white) men. Ever since Plutarch and Sueton composed their vitae of the greats of classical antiquity, to the medieval obsession with the hagiographies of holy men (and a few women) and saints, Vasari's lives of great Renaissance artists, down to the French encyclopedists, Dr. Johnson and Lytton Strachey, as well as Ranke and Droysen the genre of biographical writing (“the representation of self ” or “the reconstruction of a human life”) has become increasingly more refined. In the twentieth century male predominance has become contested and the (collective) lives of women, minorities and ordinary people are now the focus of biographical writing. This volume of Contemporary Austrian Studies offers a cross section of Austrian lives and biographical approaches to recent Austrian history. Here are what may be called traditional biographies of leading political figures through the twentieth century. We also suggest that the intellectual biographies (lives of the mind) of thinkers and professionals are fertile soil for biographical study. Moreover, the prosopographic study of common folks in the Austrian population lifts these lives from the dark matter of anonymous masses and gives rich insights into the lives ordinary Austrians have been leading.Das Verfassen von Biographien war lange Zeit eine Domäne der Männer. Von den antiken Biographien des Plutarch oder Sueton, über die mittelalterlichen Lebensbeschreibungen von Heiligen und die französischen Enzyklopädisten hat sich das biographische Schreiben zusehends verfeinert. Im 20. Jahrhundert werden vermehrt Frauen, Minderheiten und einfache Menschen Inhalt von Biographien. Dieser Band der Contemporary Austrian Studies bietet einen Querschnitt österreichischer Vitae der Zeitgeschichte. Neben traditionellen Biographien von hochrangigen PolitikerInnen wie Ignaz Seipel, Bruno Kreisky oder Alois Mock und DenkerInnen wie Viktor Frankl und Eugenie Schwarzwald oder Künstler wie Günther Anders beschreiben gewöhnliche Lebensläufe von Soldaten, Kriegsgefangenen und Bauern Österreich im 20.

Intravenous NPA for the treatment of infarcting myocardium early: InTIME-II, a double-blind comparison on of single-bolus lanoteplase vs accelerated alteplase for the treatment of patients with acute myocardial infarction

Aims to compare the efficacy and safety of lanoteplase, a single-bolus thrombolytic drug derived from alteplase tissue plasminogen activator, with the established accelerated alteplase regimen in patients presenting within 6 h of onset of ST elevation acute myocardial infarction. Methods and Results 15 078 patients were recruited from 855 hospitals worldwide and randomized in a 2:1 ratio to receive either lanoteplase 120 KU. kg-1 as a single intravenous bolus, or up to 100 mg accelerated alteplase given over 90 min. The primary end-point was all-cause mortality at 30 days and the hypothesis was that the two treatments would be equivalent. By 30 days, 6.61% of alteplase-treated patients and 6.75% lanoteplase-treated patients had died (relative risk 1.02). Total stroke occurred in 1.53% alteplase- and 1.87% lanoteplase-treated patients (ns); haemorrhagic stroke rates were 0.64% alteplase and 1.12% lanoteplase (P=0.004). The net clinical deficit of 30-day death or non-fatal disabling stroke was 7.0% and 7.2%, respectively. By 6 months, 8.8% of alteplase-treated patients and 8.7% of lanoteplase-treated patients had died. Conclusion Single-bolus weight-adjusted lanoteplase is an effective thrombolytic agent, equivalent to alteplase in terms of its impact on survival and with a comparable risk-benefit profile. The single-bolus regimen should shorten symptoms to treatment times and be especially convenient for emergency department or out-of-hospital administration. (C) 2000 The European Society of Cardiology
