    The present study case focusses in the generation of a Matlab driver for parameterized full-wave electromagnetic (EM) simulations performed in Cadence® Sigrity™ PowerSI (PowerSI), illustrating its usage to analyze several high-frequency circuits, such as microstrip filters and antennas, as well as for design optimization of a spiral inductor. The proposed methodology drives Power SI in batch mode, generates a base file with .SPD extension that can be edited in text format through Matlab commands, sets the simulation parameters and runs the simulation without opening the Power SI graphical user interface (GUI), and finally reads the simulation results for plotting or further processing with Matlab. The application of the proposed Matlab driver for PowerSI is illustrated by simulating several microstrip circuits. Furthermore, the proposed driver enables the possibility of sweeping the dimensions and other physical characteristics of the simulated circuits. Additionally, this study case describes the implementation of an optimization technique that enhances fine-tuning of the geometry for a particular spiral inductor structure simulated in a 3D EM-FEM solver module inside Power SI, namely, Cadence® Sigrity™ PowerSI 3D-EM® (PowerSI 3D-EM). Then this works compares the 3D simulation results from our simulator with the results reported in previous work in Sonnet, a 2.5D tool that uses the MoM. Finally, the propose study case presents an optimization case employing the Broyden-based input space mapping algorithm, better known as aggressive space mapping (ASM), to obtain the geometrical dimensions of the spiral inductor structure that satisfies some given design specifications

    The current research work was done in Guasaganda parish, La Maná canton, Cotopaxi province where three planting seasons were carried out with the specific objectives. The agronomic response of radish crop (Raphanus sativus L.) was identified with the inoculation of solution of efficient microorganisms (EM) per dose at 5% (0.50 ml), 10% (100 ml), and 15% (150 ml) in the rainy season. The laboratory results were analyzed in macro and micro elements of the soil, before sowing and after each sowing period. The cost-benefit relationship of the established treatments was evaluated. A completely randomized block design (CRBD) was used with four treatments (T1 5%), (T2 10%), (T3 15%), and (T4 0%) and five repetitions for each treatment. The evaluated variables were height of plant in cm, equatorial and polar diameter of bulb in cm, and production in kilograms. The treatment that stood out in the three periods with plant height, bulb diameter, and production was with the application of solution EM with the dose of 5%; the application of the established doses with EM influenced the treated soils, the pH and MO values increased. Moreover, it is remarkable that the pH ranges in the treated soils that were obtained during the investigation are optimal for the cultivation of radish.El presente trabajo de investigación se desarrolló en la parroquia Guasaganda del Cantón La Maná, Provincia de Cotopaxi, se realizó tres periodos de siembra con los objetivos específicos, se identificó la respuesta agronómica del cultivo de rábano (Raphanus sativus L.) con la inoculación de solución con microorganismos eficientes (EM) por dosis al 5% (0.50 ml), 10% (100 ml) y 15% (150 ml) en época lluviosa, se analizó los resultados de análisis de suelo en macro y micro elementos del suelo, antes de la siembra y después de cada periodo de siembra, se evaluó la relación costo y beneficio de los tratamientos establecidos. Se utilizó un diseño de bloques completamente al azar (DBCA) con cuatro tratamientos (T1 5%), (T2 10%, (T3 15%) y el (T4 0%) y cinco repeticiones por cada tratamiento; las variables evaluadas fueron altura de planta en cm, diámetro ecuatorial y polar de bulbo en cm, producción en kilogramos; el tratamiento que resaltó en los tres periodos con altura de planta, diámetro de bulbo y producción fue con la aplicación de solución con EM con la dosis al 5%; la aplicación de las dosis con EM establecidas tuvo influencia en los suelos tratados, los valores en pH y MO subieron. Se destaca que los rangos de pH en los suelos tratados que se obtuvo en el transcurso de la investigación son óptimos para el cultivo de rábano

    Get PDF
    This paper addresses the implementation of a computationally efficient optimization technique for designing structures simulated in 3D electromagnetic field solvers. A probe of concept is done by the EM-based optimization of a planar spiral inductor for high-power applications. The optimization technique employed is based on space mapping (SM) methods, more specifically on the Broyden-based input space mapping algorithm. Our optimization results confirm the efficiency of the proposed approach

    Taking the pulse of Earth's tropical forests using networks of highly distributed plots

    Get PDF
    Tropical forests are the most diverse and productive ecosystems on Earth. While better understanding of these forests is critical for our collective future, until quite recently efforts to measure and monitor them have been largely disconnected. Networking is essential to discover the answers to questions that transcend borders and the horizons of funding agencies. Here we show how a global community is responding to the challenges of tropical ecosystem research with diverse teams measuring forests tree-by-tree in thousands of long-term plots. We review the major scientific discoveries of this work and show how this process is changing tropical forest science. Our core approach involves linking long-term grassroots initiatives with standardized protocols and data management to generate robust scaled-up results. By connecting tropical researchers and elevating their status, our Social Research Network model recognises the key role of the data originator in scientific discovery. Conceived in 1999 with RAINFOR (South America), our permanent plot networks have been adapted to Africa (AfriTRON) and Southeast Asia (T-FORCES) and widely emulated worldwide. Now these multiple initiatives are integrated via ForestPlots.net cyber-infrastructure, linking colleagues from 54 countries across 24 plot networks. Collectively these are transforming understanding of tropical forests and their biospheric role. Together we have discovered how, where and why forest carbon and biodiversity are responding to climate change, and how they feedback on it. This long-term pan-tropical collaboration has revealed a large long-term carbon sink and its trends, as well as making clear which drivers are most important, which forest processes are affected, where they are changing, what the lags are, and the likely future responses of tropical forests as the climate continues to change. By leveraging a remarkably old technology, plot networks are sparking a very modern revolution in tropical forest science. In the future, humanity can benefit greatly by nurturing the grassroots communities now collectively capable of generating unique, long-term understanding of Earth's most precious forests.Additional co-authors: Susan Laurance, William Laurance, Francoise Yoko Ishida, Andrew Marshall, Catherine Waite, Hannsjoerg Woell, Jean-Francois Bastin, Marijn Bauters, Hans Beeckman, Pfascal Boeckx, Jan Bogaert, Charles De Canniere, Thales de Haulleville, Jean-Louis Doucet, Olivier Hardy, Wannes Hubau, Elizabeth Kearsley, Hans Verbeeck, Jason Vleminckx, Steven W.
