    Electrical Loads and Power Systems for the DEMO Nuclear Fusion Project

    EU-DEMO is a European project, having the ambitious goal to be the first demonstrative power plant based on nuclear fusion. The electrical power that is expected to be produced is in the order of 700–800 MW, to be delivered via a connection to the European High Voltage electrical grid. The initiation and control of fusion processes, besides the problems related to the nuclear physics, need very complex electrical systems. Moreover, also the conversion of the output power is not trivial, especially because of the inherent discontinuity in the EU-DEMO operations. The present article concerns preliminary studies for the feasibility and realization of the nuclear fusion power plant EU-DEMO, with a special focus on the power electrical systems. In particular, the first stage of the study deals with the survey and analysis of the electrical loads, starting from the steady-state loads. Their impact is so relevant that could jeopardy the efficiency and the convenience of the plant itself. Afterwards, the loads are inserted into a preliminary internal distribution grid, sizing the main electrical components to carry out the power flow analysis, which is based on simulation models implemented in the DIgSILENT PowerFactory software

    BPM, Agile, and Virtualization Combine to Create Effective Solutions

    The rate of change in business and government is accelerating. A number of techniques for addressing that change have emerged independently to provide for automated solutions in this environment. This paper will examine three of the most popular of these technologies-business process management, the agile software development movement, and infrastructure virtualization-to expose the commonalities in these approaches and how, when used together, their combined effect results in rapidly deployed, more successful solutions

    The Impact Of Interactive Experience And Online Service Quality On Customer Satisfaction With The Mediation Of Consumer Value Perception

    Get PDF
    This article explores the intricate dynamics influencing customer satisfaction in the digital commerce landscape, with a specific focus on interactive experiences, online service quality, and consumer value perception. The research reveals significant direct effects, indicating that both interactive experiences and online service quality play crucial roles in shaping consumer value perception, subsequently influencing customer satisfaction. Furthermore, the study uncovers significant indirect effects, illustrating that enhancements in interactive experiences and online service quality not only directly impact customer satisfaction but also exert substantial influence through the mediating role of consumer value perception. The findings highlight the interconnected nature of these factors and emphasize the need for businesses to adopt a holistic approach to optimize overall customer satisfaction. This research provides valuable insights for companies, including those in dynamic markets like PT. Bali Indoraya, guiding them in refining digital strategies and fostering enduring customer relationships in the continually evolving digital commerce landscape.

    Predictable Disruption Tolerant Networks and Delivery Guarantees

    Full text link
    This article studies disruption tolerant networks (DTNs) where each node knows the probabilistic distribution of contacts with other nodes. It proposes a framework that allows one to formalize the behaviour of such a network. It generalizes extreme cases that have been studied before where (a) either nodes only know their contact frequency with each other or (b) they have a perfect knowledge of who meets who and when. This paper then gives an example of how this framework can be used; it shows how one can find a packet forwarding algorithm optimized to meet the 'delay/bandwidth consumption' trade-off: packets are duplicated so as to (statistically) guarantee a given delay or delivery probability, but not too much so as to reduce the bandwidth, energy, and memory consumption.Comment: 9 page

    How to use the International Classification of Functioning, Disability and Health as a reference system for comparative evaluation and standardized reporting of rehabilitation interventions

    Get PDF
    Rehabilitation aims to optimize functioning of persons experiencing functioning limitations. As such the comparative evaluation of rehabilitation interventions relies on the analysis of the differences between the change in patient functioning after a specific rehabilitation intervention versus the change following another intervention. A robust health information reference system that can facilitate the comparative evaluation of changes in functioning in rehabilitation studies and the standardized reporting of rehabilitation interventions is the International Classification of Functioning, Disability and Health (ICF). The objective of this paper is to present recommendations that Cochrane Rehabilitation could adopt for using the ICF in rehabilitation studies by: 1) defining the functioning categories to be included in a rehabilitation study; 2) specifying selected functioning categories and selecting suitable data collection instruments; 3) examining aspects of functioning that have been documented in a study; 4) reporting functioning data collected with various data collection instruments; and 5) communicating results in an accessible, meaningful and easily understandable way. The authors provide examples of concrete studies that underscore these recommendations, whereby also em-phasizing the need for future research on the implementation of specific recommendations, e.g. in meta-analysis in systematic literature reviews. Furthermore, the paper outlines how the ICF can complement or be integrated in established Cochrane and rehabilitation research structures and methods, e.g. use of standard mean difference to compare cross-study data collected using different measures, in developing core outcome sets for rehabilitation, and the use of the PICO model. © 2019 EDIZIONI MINERVA MEDICA

    En las siguientes líneas se plantea un artículo de reflexión que tiene en cuenta parte del marco teórico que sustenta la investigación titulada “Prácticas pedagógicas que promueven la competencia argumentativa escrita (CAE) en niños campesinos de los grados 4° y 5° del Centro Educativo Municipal La Caldera, Sede Principal de Pasto”, desarrollada en el año 2012. En él se contemplan los aportes de las ciencias del lenguaje y la comunicación, la teoría de la argumentación, la didáctica de la lengua escrita y los géneros discursivos, que dan cuenta de la necesidad de desarrollar la capacidad crítica en los estudiantes a través de la argumentación, lo cual implica transformar las prácticas pedagógicas para que se alejen de la transmisión de conocimientos y den paso a la comunicación, para que la palabra escrita sea apropiada de manera significativa
