Application of frequency ratio and logistic regression to active rock glacier occurrence in the Andes of San Juan, Argentina
(Elsevier Science, 2010-01)
This study employs statistical modeling techniques and geomorphological mapping to analyze the distribution of active rock glaciers in relation to altitude, aspect, slope, lithology and solar radiation using optical remote ...
Comparing lumped and distributed parameters models in transmission lines during transient conditions
(2014-01-01)
The solutions of differential equations of transmission line are generally difficult to obtain due to the convolution integral present. Considering this, there are models proposed for the study of electromagnetic transients ...
Nonlocal frequency analysis of nanosensors with different boundary conditions and attached distributed biomolecules: an approximate method
(Springer Wien, 2016-04-26)
Nanosensors are simple engineering devices designed to detect and convey informations about nanoparticles and biomolecules. The nanosized mass sensors are based on the fact that the resonant frequency is sensitive to the ...
Modeling and measuring double-frequency jitter in one-way master-slave networks
(ELSEVIER SCIENCE BV, 2009)
The double-frequency jitter is one of the main problems in clock distribution networks. In previous works, sonic analytical and numerical aspects of this phenomenon were studied and results were obtained for one-way ...
Hopf Bifurcation Analysis of Distributed Delay Equations with Applications to Neural Networks
(World Scientific, 2015-11)
In this paper, we study how to capture smooth oscillations arising from delay-differential equations with distributed delays. For this purpose, we introduce a modified version of the frequency-domain method based on the ...
High frequency input impedance modeling of low-voltage residential installations - influence on lightning overvoltage simulations results
(2014-11-25)
The overvoltage level of a system is strongly dependent on the connected loads and with more precise models, better and more reliable simulation results are obtained. This paper presents the input impedance characteristics, ...
Heterogeneous self-arrested ruptures leading to spatial variability of radiated energy and Doppler effect of the observed corner frequency
(2023)
The study of the strong ground motion is of utmost relevance because the amplitude of seismic waves and their frequency content could severely damage structures. As both the amplitude and the frequency content directly ...
Dinâmica da distribuição diamétrica de povoamentos de Pinus taeda L. em diferentes idades e espaçamentos
(Universidade Federal de Santa MariaBRRecursos Florestais e Engenharia FlorestalUFSMPrograma de Pós-Graduação em Engenharia Florestal, 2008-07-03)
The diameter distribution through of mathematical formulations can be a factor of importance to the planning and control of forest activities, determining the production and growth of the trees, allowing the knowledge of ...
