A Phase-Locked Loop for the Synchronization of Power Quality Instruments in the Presence of Stationary and Transient Disturbances
2007
Power quality instrumentation requires accurate fundamental frequency estimation and signal synchronization, even in the presence of both stationary and transient disturbances. In this paper, the authors present a synchronization technique for power quality instruments based on a single-phase software phase-locked loop (PLL), which is able to perform the synchronization, even in the presence of such disturbances. Moreover, PLL is able to detect the occurrence of a transient disturbance. To evaluate if and how the synchronization technique is adversely affected by the application of stationary and transient disturbing influences, appropriate testing conditions have been developed, taking int…
Impact of industrial environments on the PC-based measurements
2007
In the paper we present a simple and fast procedure to evaluate the impact of the electromagnetic disturbances, which can be present in the industrial locations, on the measurements performed by a generic PC-based measurement instrument. The method is conceived starting from the data obtained by subjecting the instruments to the disturbances prescribed by the IEC-61326 standard. The results show that, even under heavy disturbances, the common good practices of shielding and grounding allow a correct employment of this kind of instrumentation.
Single thermal zone balance solved by Transfer Function Method
2005
We present an algorithm that uses the Z-transform operator to face the problem of heat transmission in a single thermal zone composed by multilayered walls. The method is very flexible and could be adopted to calculate the transfer function coefficients able to simulate the thermal behaviour of a room in free floating. Knowing the transfer function coefficients, it is possible to simulate the dynamic profile of each inner surfaces temperature and furthermore of the inner air temperature. The proposed algorithm is fully described granting maximum clarity. The explicitness of all steps of the calculus make possible the definition of a method that is able to vary all of the calculus parameters…
TRACE and RELAP5 Codes for Beyond Design Accident Condition Simulation in the SPES3 Facility
2012
Code validation on qualified experimental data is a fundamental issue in the design and safety analyses of nuclear power plants. The SPES3 facility is being built at the SIET laboratories for an integral type SMR simulation, in the frame of an R&D program on nuclear fission, funded by the Italian Ministry of Economic Development and led by ENEA. The facility, based on the IRIS reactor design, reproduces the primary, secondary and containment systems with 1:100 volume scale, full elevation and prototypical fluid and thermal-hydraulic conditions. It is suitable to test the plant response to design and beyond design accidents in order to verify the effectiveness of the primary and containm…
An Approach to Rank Noise Pollution in Workplaces
2013
In this paper, we describe a method for classifying the workplaces as regards the noise risk. This method provides an univocal classification of work area and allows to correctly implement the control measures in accordance with a suitable priority scale. Finally, this method can be easily adjusted to respect various national standards.
Facilitating Elements for the Transmission of the Entrepreneurial Spirit in the Classroom
2014
There have been countless tests made to confirm that creativity is a critical skill for entrepreneurs and their entrepreneurial training (Schmidt, J. et al. 2012), even more, practices on divergent thinking increases the entrepreneurial skills of students to generate a greater number and range of ideas, but not, their approaches to solve problems in a creative way. This situation raises a number of questions that should be analyzed before adding creativity and techniques to improve the training of creative thinking to studies (classes), about and in entrepreneurship, as a training channel, improvement or even to the generation of entrepreneurs. Our goal is to show that entrepreneurship is a…
Family and non-family businesses in iran:Coupling among innovation, internationalization and growth-expectation
2021
Gallo and Sveen, in 1991, specified problems of whether family businesses can take advantage of factors facilitating internationalization. We compare family and non-family businesses in innovation, export, and growth-expectation, and consider how outcomes are aligned, with a coupling that may be loose, with a synergy that benefits the business. This raises a further issue, is governance of a business affecting not only each of the outcomes but also their coupling. A representative sample of 530 Iranian businesses was surveyed in 2018 for Global Entrepreneurship Monitor. Innovation, export, and growth-expectation are found to be lower in family businesses. Coupling between innovation and exp…
Are Problems with Violence and the Lack of Public Safety a Barrier to Entrepreneurship?
2015
Scholars cite violence as a potential barrier to entrepreneurial activity in El Salvador. Using AHP, this research aims to rank the socioeconomic and political barriers to entrepreneurship in El Salvador. The analysis stresses the importance of citizen security as a barrier to entrepreneurial activity.
Ethical Entrepreneurship Training. Theoretical Reflection and Case Analysis
2014
Abstract In this paper we first reflect on the theoretical foundation of ethical entrepreneurship training in the field of economy. In this sense, we try to establish briefly the theoretical and historical assumptions of ethical entrepreneurship, especially from a review of the work of Adam Smith, professor of Moral Philosophy and central figure in the birth of the modern economy. We then present a definition of entrepreneurial activity, which is closely linked to a social and ethical dimension of economy and to the internal goods of economic activity. On the basis of these considerations, we propose some objectives of training for ethical entrepreneurship. Finally, we present a case study …
Comunicar Conocimientos vs. Organizar el Conocimiento: la Gestión del Gen-preneur en el Aula
2014
Se han hecho innumerables pruebas para constatar que la creatividad es una habilidad crítica para los emprendedores y su formación emprendedora (Schmidt, J. et al. 2012), incluso se ha detectado que la práctica sobre el pensamiento divergente incrementa las habilidades emprendedoras de los estudiantes para generar un mayor número y rango de ideas, pero NO así, sus enfoques para la resolución creativa de problemas. Nuestro objetivo será mostrar que el emprendimiento es una faceta de la creatividad y que, el emprendedor "oculto" en el discente, necesitará observar y confirmar la existencia de condicionantes externos suficientes, para liberar su actitud emprendedora retenida, asimismo, será im…
