Modelos série de potência com excesso de zeros observáveis e latentes
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Estatística - PPGEsCâmpus São Carlos, 2016-09-28)
The present work's main objective is to study the significance of zeros in an observable
and latent data. In observable data set that occur excess of zeros, its common to have
sobredispersion. In this sense, the models ...
Modelos de sobrevivência bivariados induzidos por fragilidade
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2022-07-18)
Frailty models have been developed to quantify both heterogeneity as well as association in multivariate time-to-event data. The frailty distributions used in many studies include the gamma, inverse Gaussian (IG) or stable ...
Aplicação do método dos elementos discretos formados por barras na simulação de processo de ruptura de materiais quase frágeis
(Universidade Federal do PampaUNIPAMPABrasilCampus Alegrete, 2017)
Materiales compuestos reforzados por fibras cortas : estudio utilizando el método de los elementos discretos formado por barrasShort fiber reinforced composites : analysis using lattice model
(Asociación Sudamericana de Ingeniería Estructural. Asociación Paraguaya de Estructura, 2016-11-02)
El uso de materiales multifásicos permite obtener un nuevo material con propiedades más adecuadas al uso que se le quiera dar al compuesto. En la interacción de las fases influyen tanto las propiedades mecánicas intrínsecas ...
An improved multi-unit nuclear plant seismic probabilistic risk assessment approach
(Elsevier Science BV, 2018)
This paper proposes an improved approach to external event probabilistic risk assessment for multi-unit sites. It considers unit-to-unit dependencies based on the integration of the copula notion, importance sampling, and ...
Multi-factor authentication model based on multipurpose speech watermarking and online speaker recognition
(Springer, 2017-03)
In this paper, a Multi-Factor Authentication (MFA) method is developed by a combination of Personal Identification Number (PIN), One Time Password (OTP), and speaker biometric through the speech watermarks. For this reason, ...
H∞ And H2 Nonquadratic Stabilisation Of Discrete-time Takagi-sugeno Systems Based On Multi-instant Fuzzy Lyapunov Functions
(Taylor and Francis Ltd., 2015)
Scenario-based seismic performance assessment of a Chilean hospital
(2015)
Hospitals are critical facilities that are essential for providing first-aid response to communities in the aftermath of disasters such as earthquakes. The seismic performance of these facilities is highly dependent on the ...
Análise da influência do empacotamento dos agregados na porosidade do concreto
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Construção Civil, 2014-09-09)
The resistance to external actions which the concrete element is subject is related to the porosity of concrete. One of the factors that interfere in resistance is the water / cement ratio, where the higher the water / ...
