Straight-line conventional transient rate analysis for long homogeneous and heterogeneous reservoirs
(Universidad Nacional de Colombia Sede Medellín, 2012)
A linear flow regime is a very important flow regime presented in fractured wells, horizontal wells and long reservoirs. Either pressure-transient analysis or rate-transient analysis may be affected by a linear flow regime. ...
Desenvolvimento de um software pré-processador gráfico para análise de transitórios em subestações
(Universidade Federal de Santa MariaBREngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia Elétrica, 2016-03-22)
The following work presents a graphical pre-processor software as an alternative version of
the Electromagnetic Transients Program (ATP-EMTP). It was developed to aid in the analysis
of electromagnetic transients in power ...
Sparse network equivalent based on time-domain fitting

Uma arquitetura para detecção online de transientes em sinais de eletrocardiograma sobre o protocolo PM-AH
(SBEB - Sociedade Brasileira de Engenharia Biomédica, 2012-12)
A correct identification of transients in the ECG (electrocardiogram) can assist processing methods for ECG
signals, since this type of event degrades the signal and can be misleading. Therefore, this paper proposes ...
Simulations of electromagnetic transients in a transmission line using state variables
(Ieee, 2008-01-01)
Transmission lines can be represented by a set of pi circuits. These circuits can be modeled by state variables and solved using trapezoidal integration. This paper presents a mathematical routine that, using trapezoidal ...

Theory does not meet experiment: transient dynamics changes patterns of exclusion in an intraguild predation system
(2017-10-01)
Although empirical verifications of ecological theory are essential for the advance of our understanding of ecosystems functioning, they are often hard to obtain or even impractical. In this work we perform a detailed ...
Frequency-dependent line model in the time domain for simulation of fast and impulsive transients
(2016-09-01)
A new transmission line model is proposed based on the well-established Bergeron method. The conventional Bergeron model is characterized by the line representation by concentrated longitudinal and transversal parameters, ...
