Proposal of a new stability concept to detect changes in unsupervised data streams
(Pergamon-ElsevierOxford, 2014-11-15)
Learning from continuous streams of data has been receiving an increasingly attention in the last years. Among the many challenges related to mining data streams, change detection is one topic frequently addressed. Being ...
Complexation of a 1-indanone thiosemicarbazone with hydroxypropyl-beta-cyclodextrin enhances its activity against a Hepatitis C Virus surrogate model
(American Scientific Publishers, 2015-02)
The current standard of care of the infection by hepatitis C virus (HCV) is effective in a limited number of patients and the high cost hinders therapy affordability and compliance. In this context, the research of new ...
Economic design of two-stage (X)over-bar charts: the Markov chain approach
(Elsevier B.V., 2005-01-28)
When the (X) over bar chart is in use, samples are regularly taken from the process, and their means are plotted on the chart. In some cases, it is too expensive to obtain the X values, but not the values of a correlated ...
In vivo phagocytosis and hematology in astyanax altiparanae, a potential model for surrogate technologyFagocitose in vivo e hematologia em astyanax altiparanae, um potencial modelo para tecnologia de propagação mediada
(2020-04-01)
Although the potential of surrogate propagation technology for aquaculture and conservation of Neotropical fish, the poor understanding of the host immune system may results in rejection and destruction of the donor material. ...
Sensitivity and uncertainty analysis of the carbon and water fluxes at the tree scale in Eucalyptus plantations using a metamodeling approach
(2015-08-25)
Understanding the consequences of changes in climatic and biological drivers on tree carbon and water fluxes is essential in forestry. Using a metamodeling approach, sensitivity and uncertainty analyses were carried out ...
An experience with surrogate functions on the design of a transcutaneous energy transfer system
(2015-01-01)
A transcutaneous Energy Transfer (TET) is a system that uses electromagnetic fields to transfer power from outside the body to an artificial organ (AO) inside the body. In this work a systematic approach to obtain an optimal ...
Detecting nonlinearity in short and noisy time series using the permutation entropy
(Elsevier Science, 2017-11)
Permutation entropy contains the information about the temporal structure associated with the underlying dynamics of a time series. Its estimation is simple, and because it is based on the comparison of neighboring values, ...
Risk estimates for persistent high-risk human papillomavirus infections as surrogate endpoints of progressive cervical disease critically depend on reference category: analysis of the combined prospective cohort of the New Independent States of the Former Soviet Union and Latin American Screening Studies
(Royal Soc Medicine Press LtdLondonInglaterra, 2011)
An approach using Lagrangian/surrogate relaxation for lot-sizing with transportation costs
(Sociedade Brasileira de Pesquisa Operacional, 2009-08-01)
Neste trabalho estuda-se um problema de dimensionamento de lotes e distribuição que envolve além de custos de estoques, produção e preparação, custos de transportes para o armazém da empresa. Os custos logísticos estão ...
