Characterization of IP-Based Communication for Smart Grid Using Software-Defined Networking

2018

The smart grid (SG) approach is based on a strong interaction between the network communication infrastructure and the power grid. Usually the management of the infrastructure is done by the distribution system operators (DSOs) that are worried about the increasing managing complexity due to the presence of increasing number of distributed energy resources and electrical vehicles. The use of software-defined networking (SDN) may simplify the network configuration and management for DSO, as highlighted from previous research works. The objective of this paper is to introduce and characterize an internet protocol (IP)-based communication architecture with specialized SDN bridges operating als…

The Smart Land Paradigm in the Sicani Territorial Archipelago

2017

With the aim to identify the specific identities of the Sicani territory, to interpret them in a perspective of innovative development and to define strategies capable of intercepting programming in progress, it has been deepened the “territorial archipelago” theoretical framework , recognizing it into the Sicani territory and trying to use it as the base of a possible development of a Smart Land, as a “non-gravitational” paradigm able to recognize and to direct the new relations of the rur-urban local systems.

Enhancing the Iterative Smoothed Particle Hydrodynamics Method

2021

Motivated by recent research on the iterative approach proposed for the smoothed particle hydrodynamics (ISPH) method, some ideas to improve the process are introduced. The standard procedure is enhanced iterating on the residuals preserving the matrix-free nature of the process. The method is appealing providing reasonable results with disordered data distribution too and no kernel variations are needed in the approximation. This work moves forward with a novel formulation requiring a lower number of iterations to reach a desired accuracy. The computational procedure is described and some results are introduced to appreciate the proposed formulation.

NETWORK ANALYSIS OF A TOURIST DESTINATION

2014

This paper relates to the study of relationships within a tourist destination in order to prove the existence of structural models around which the entire supply system is developed. All this is made possible by the analysis of the links existing between businesses belonging to the destination. A useful tool for this purpose is Social Network Analysis (SNA), which provides a series of indicators and techniques to study the complexity of the network of relationships within a tourist destination and allows identifying the existence of a possible reference framework that can characterize the specificity of the destination. Based on the results from a previous analysis carried out in the San Vi…

Network analysys of a tourist destination

2014

We have focused on the role played by three families within the tourist destination assessing their role as an aggregating and driving force. This has been made possible by using one of the tools provided by SNA, namely Ego network analysis. This tool has allowed us to focus our attention on the role that individual businesses belonging to the three main families in San Vito Lo Capo (that we call Ego) play in the management of the destination. In particular, since the network of business relationships at this scarcely developed destination (i.e., in terms of density), the subjects are more likely to form relationships with those individuals who are acknowledged leaders. Within these tighter…

Guanxi, performance and innovation in entrepreneurial service projects.

2012

This paper analyzes the role played by two dimensions of entrepreneurs’ private social capital in the survival, growth and innovativeness of entrepreneurial service ventures: local size and preferential attachment degree. We build a bi-dimensional measure of social capital based on network models and a methodology to estimate this measure for any group of entrepreneurs. Based on a survey of service entrepreneurs who launched their business in the city of Shanghai, we show that roles played by each dimension are quite different. A large local size of the network increases the chances of survival of the new venture. However, the chance to become a dynamic venture is only related to entreprene…

2020

El presente estudio presenta el diseño y validación del instrumento UN-DIGECO (University Digital Ecosystem), orientado a conocer el Ecosistema Digital Universitario, identificando las dimensiones asociadas al uso que hacen los estudiantes de los medios sociales (MMSS) y/o aplicaciones digitales. La validación de contenido y comprensión se efectuó en tres fases: construcción, refinado y validación psicométrica, mediante el análisis factorial confirmatorio, apoyado en el constructo teórico inicial. Se diseñaron ítems –recabando información de instrumentos similares-, acordes a indicadores adscritos a seis dimensiones: aprendizaje, interacción social, creación de contenidos, consumo online, o…
