Dynamic and static calibration of ultra-low-voltage, digital-based operational transconductance amplifiers
(2020) [Artigo de periódico]The calibration of the effects of process variations and device mismatch in Ultra Low Voltage (ULV) Digital-Based Operational Transconductance Amplifiers (DB-OTAs) is addressed in this paper. For this purpose, two dynamic ... -
Dynamic behaviour of an electrolyser with a two phase solid-liquid electrolyte : Part I : spectral analysis of potential fluctuations
(1994) [Artigo de periódico]The dynamic behaviour of a simplified electrolyser with a two phase solid-liquid electrolyte was investigated. The current-voltage curve and the impedance of the working electrode (current collector) was measured. In ... -
Dynamic constrained coalition formation among electric vehicles
(2014) [Artigo de periódico]Background: The use of electric vehicles (EVs) and vehicle-to-grid (V2G) technologies have been advocated as an efficient way to reduce the intermittency of renewable energy sources in smart grids. However, operating on ... -
Dynamic evaluation method of lower limb joint alignment with parallel feet (MADAAMI-P) : content validation and reproducibility
(2019) [Artigo de periódico]Neutral static alignment, normal movement and a satisfactory segmental interrelationship are described as significant factors in normal asymptomatic function and, when altered, increase the risk of lesions in the lower ... -
A dynamic extension for LgV controllers
(1999) [Artigo de periódico]A dynamic state feedback control structure is proposed in this paper. The scheme is conceived as an adaptive controller with the equilibrium in an LgV control law as the uncertain parameter, which allows the implementation ... -
Dynamic facilitation picture of a higher-order glass singularity
(2010) [Artigo de periódico]We show that facilitated spin mixtures with a tunable facilitation reproduce, on a Bethe lattice, the simplest higher-order singularity scenario predicted by the mode-coupling theory (MCT) of liquid-glass transition. ... -
Dynamic fracture analysis of concrete or rock plates by means of the discrete element method
(2009) [Artigo de periódico]The authors apply the so-called Discrete Element Method (DEM) to determine the dynamic response of concrete and rock plates of various sizes that fracture under the action ofstatic and dynamic loading. When, on account of ... -
Dynamic-mechanical properties as a function of luffa fibre content and adhesion in a polyester composite
(2020) [Artigo de periódico]In this work, the characteristics of a vegetable fibre (luffa cylindrica) polyester composite are studied as a function of fibre surface treatment (with NaOH, Ca(OH)2 and silane) and fibre content (30%, 40% and 50%). ... -
Dynamic modular networks model mediated by confinement
(2019) [Artigo de periódico]We present a model for network transformation mediated by confinement, as a demonstration of a simple network dynamics that has a direct connection with real world quantities. The model has the capacity of generating complex ... -
Dynamic of Langmuir wave decay in two dimensions
(2008) [Artigo de periódico]The present paper reports on the first two-dimensional 2D self-consistent solution of weak turbulence equations describing the evolution of electron-beam-plasma interaction in which quasilinear as well as nonlinear three-wave ... -
Dynamic of pressure-deformation curve in uniaxial compression test in different load times
(2017) [Artigo de periódico]The loading application time by machinery tires and agricultural tires is one of the factors of soil compaction. We evaluated the effect of loading reduction time in uniaxial compression test, in laboratory, in some physical ... -
Dynamic output feedback for discrete-time systems under amplitude and rate actuator constraints
(2008) [Artigo de periódico]This work proposes a technique for the design of stabilizing dynamic output feedback controllers for discrete-time linear systems with rate and amplitude saturating actuators. The nonlinear effects introduced by the ... -
A dynamic perspective on L2 pronunciation development : bridging research and communicative teaching practice
(2019) [Artigo de periódico]The main goal of this paper is to raise language teachers’ awareness of the need to incorporate research-based pronunciation teaching into their communicative language classes in an ongoing and integrated manner. To do so, ... -

Dynamics of ammonium and pH in the solution of soils with different salinity levels, growing irrigated rice
(2012) [Artigo de periódico]Rice in Rio Grande do Sul State is grown mostly under flooding, which induces a series of chemical, physical and biological changes in the root environment. These changes, combined with the presence of rice plants, affect ... -
Dynamics of antiproton plasma in a timedependent harmonic trap
(2021) [Artigo de periódico]An antiproton plasma confined in a quasi-1D device is described in terms of a self-consistent fluid formulation using a variational approach. Unlike previous treatments, the use of the time-dependent variational method ... -
Dynamics of cattle production in Brazil
(2016) [Artigo de periódico]Movement of livestock production within a country or region has implications for genetics, adaptation, well-being, nutrition, and production logistics, particularly in continental-sized countries, such as Brazil. Cattle ...
