Evaluation of three different osteosynthesis methods for mandibular angle fractures: Vertical load test
(2016-01-01)
The aim of this study was to evaluate the mechanical behavior of different rigid fixation methods in mandible angle fractures. Three different plates were tested: one 4-hole grid miniplate, one 8-hole curved grid miniplate, ...
Full-State Feedback Equivalent Controller for Active Damping in LCL-Filtered Grid-Connected Inverters Using a Reduced Number of Sensors
(Institute Of Electrical And Electronics Engineers, 2015-10)
This paper presents a method for the active damping of a grid-tie LCL inverter. This method is based solely on the feedback of the injected current into the grid, and is applicable to any linear current controller. It ...
Observer-Based Grid-Voltage Sensorless Synchronization and Control of a VSI-LCL Tied to an Unbalanced Grid
(Institute of Electrical and Electronics Engineers, 2019-07)
This paper proposes an observer-based grid-voltage sensorless strategy that allows to implement the synchronization and control of an LCL grid-tied voltage source inverter. By using exclusively the measurement of the current ...
Enhancing the BYG gridification tool with state-of-the-art Grid scheduling mechanisms and explicit tuning support
(Elsevier, 2012-01)
Grid Computing allows scientists and engineers to run compute intensive experiments that were unfeasible not so long ago. On the downside, for users not proficient in distributed technologies, programming for Grids is ...
Speed cells in the medial entorhinal cortex
(Nature Publishing Group, 2015-07)
Grid cells in the medial entorhinal cortex have spatial firing fields that repeat periodically in a hexagonal pattern. When animals move, activity is translated between grid cells in accordance with the animal's displacement ...
Malhas de amostragem retangular e hexagonal na geração de mapas de fertilidade e aplicação para agricultura de precisão
(Universidade Federal de Santa MariaBRTecnologia em Agricultura de PrecisãoUFSMPrograma de Pós-Graduação em Agricultura de Precisão, 2016-09-15)
Sample grid s are essential when we want to represent the variation in chemical and physical properties of the soil, being essential to know its features. In this way, this study aimed to relate the efficiency and practicality ...
Santiago, Capital City: Forms of the Periphery, 1836-1875
(2016)
In the first half of the XIX century, Santiago territorial scale registers, two ways of growth that precedes to the urban expansion and modernization to be inaugurated towards 1870: one, by extending the model of the ...
