Historia del pensamiento económico
No full textFil: Perrone, Guido. Universidad Nacional de Quilmes. Departamento de Economía y Administración; Argentina.El objetivo de esta asignatura es desarrollar un curso que introduzca a los alumnos en el
estudio de los principales paradigmas desarrollados en el campo de la historia del
pensamiento económico, con la finalidad de que los mismos reconozcan y se formen una
idea pertinente acerca de las diferentes concepciones, abordajes y definiciones
disciplinarias a que estos paradigmas dieron lugar.
Para tal objetivo, el desarrollo de la asignatura se realizará presentando esos distintos
paradigmas del pensamiento económico de acuerdo a la manera en que fue evolucionando
la propia disciplina. Se buscará poner en debate la problematización de lo económico en
vinculación, por una parte, con el contexto socioeconómico en que surgieron estos
paradigmas y, por otra, con el propio desarrollo de las ideas en el campo de la economía
A Low-Cost Optical Sensor for Non contact Vibration Measurements
Full text linkThis paper presents a new noncontact method to measure vibrations by using a low-cost optical approach that is able to provide a submicrometer resolution. The transducer exploits a simple optical setup based on an intensity-detection scheme that is implemented with plastic optical fibers, whereas innovative non demanding spectral data processing allows compensation of the vibrating surface reflectivity and the gains of the measurement chain. The performance of the proposed system has been assessed, through comparison with other techniques, by performing several measurement tests that use targets vibrating at frequencies from a few hertz up to several tens of kilohertz and with different values of reflectivit
A correction to the two-dimensional BPM for the analysis of waveguide lenses
No full textA correction to the two-dimensional (2D) BPM analysis of integrated optics lenses based on the effective refractive index (ERI) method is proposed. The modification takes into account the modal conversion effects in depth, by introducing a proper fictitious element in the 2D-BPM analysis. Comparisons with the three-dimensional (3D) BPM results show the validity of this method, which overcomes the CPU time limitations of a 3D-BPM
Foundations for integrated optics modeling
No full textMicrowave Photonics: from Components to Applications and Systems deals with the rapidly growing area of Microwave Photonics, and includes an extended study of the interactions between optical signals and microwave (f > 1GHz) and millimeter-wave (f > 30 GHz) electrical signals for broadband applications. Today, the large development of photonic devices and technologies leads to an ever-increasing interest in this cross-disciplinary field. This book covers all aspects of the field of microwave photonics, including components, modeling methods, circuits and broadband systems for a wide variety of applications, such as telecommunications, radar and wireless systems. The authors of the topics presented in this book include key-note specialists from Europe, Israel, and the United State
