Effects of Electrical Parameters of Induction Generator on the Transient Voltage Stability of a Fixed Speed Wind Turbine
2008
This paper describes the effect of electrical parameters of the induction generator on the transient voltage stability of a fixed speed wind turbine connected to a simple grid; the dynamic behavior of a wind turbine connected to the grid is examined. The model of the fixed speed wind turbine has been developed in the simulation tool Matlab/Simulink. Itpsilas composed by the induction generator, the shaft system, the aerodynamic model of the wind turbine rotor and the pitch control system. Using this model, a three-phases fault is applied close to the wind turbine and cleared by disconnecting the faulted line. The effect of different electrical parameters of the induction generator on the vo…
Forms and Functions of the Real Estate Market of Palermo (Italy). Science and Knowledge in the Cluster Analysis Approach
2016
The analysis of the housing market of a city requires suitable approaches and tools, such as data mining models, to represent its complexity which derives on many elements, e.g. the type of capital asset-house is a common good and an investment good as well, the heterogeneity of the urban areas—each of them has own historical and representative values and different urban functions—and the variability of building quality. The housing market of the most densely populated area of Palermo (Italy), corresponding to ten districts, is analyzed to verify the degree of its inner homogeneity and the relations between the quality of the characteristics and the price of the properties. Five hundred set…
La Universidad podría ser mejor
2017
La universidad podría ser mejor. Todos los que hemos pensado así alguna vez lo que denota interés, puede que hasta afecto, por la institución , lo hemos hecho tras sufrir alguna decepción que ha provocado en nosotros una respuesta primaria modelo, efecto de la decepción por un servicio defectuosamente prestado: habría que regular mejor lo que queremos que la universidad sea. Esa respuesta primaria nos lleva, con mayor o menor grado de consciencia, a idear procedimientos para asegurar que las personas responsables hagan lo que creemos que deben hacer para que la universidad preste el servicio deseado. Sólo así nos protegeremos de los perniciosos efectos que sobre el buen funcionamiento de la…
¿Puede hablarse de consenso constructivista en la educación científica?
2021
Artículo colectivo sobre qué entendemos por "constructivismo" en enseñanza de las ciencias. In this paper we analyse some of the criticisms that are being made to the «constructivist paradigm» and their implications on the development of the didactic of the sciences as a theoretical body knowledge.
Considerations Regarding the Relevance of Direct Foreign Investments in the Global Economy
2019
Abstract It is well known that the current business world, and also the investments, today are based on the global markets expansion. Contemporary reality shows us the image of a world which is irreversibly evolving towards the businesses globalization and the companies’ internationalization. The internal markets often become overcrowded, and the companies access more profoundly the global marketplace, which not only provides a place for all competitors, but also represents a source of new advantages for all. In the context of globalization the investment activity has gained new dimensions, becoming a global one, with serious implications, which manifest itself over the national economies a…
Keys to success in investment rounds by immigrant entrepreneurs in Silicon Valley
2019
[EN] This study presents an updated diagnosis of the SV ecosystem itself and offers an insight into the entrepreneurial mobility trends prospects and expectations of the growing number of start-ups launched by immigrant entrepreneurs arriving in SV. The purpose is to determine and rank the attributes most valued by investors when assessing projects and start-ups founded by immigrant entrepreneurs. The model of analysis composed by three hypotheses leads to a series of findings about the profile and expectations of the immigrant entrepreneurs, and reveals remarkable hints and key targets to be met by immigrant entrepreneurs in SV in order to successfully close investment rounds in a hypercom…
The Effect of Systemic Banking Crises on Entrepreneurship
2014
Economic crises have mixed effects on entrepreneurship. Through demand shocks, credit constraints, and unemployment, systemic banking crises affect the rate of start-up business creation, although the extent of their impact varies. Consequently, previous studies on the effect of crises on Entrepreneurship are inconclusive. The surge of global demand coupled with low credit availability reduces the prospects for new businesses. On the other hand, job losses caused by an economic crisis might lead many entrepreneurs to undertake new projects. These inconsistent conclusions highlight the need for more studies that explore the effect of systemic banking crises on entrepreneurship. This article …
The performance of entrepreneurial small‐ and medium‐sized enterprises
2012
Innovation is an important driver of economic growth for it leads to new products and services, enhanced quality, and lower prices. In an increasingly competitive global market, innovation turns out to be essential to secure a viable competitive position.

To identify differences between innovative and non‐innovative small and medium enterprises in the service industry, both descriptive and statistical analyses are performed on financial dat…
