Copper distribution in Mediterranean forest ecosystems Distribución del cobre en ecosistemas forestales de tipo Mediterraneo
(2002)
We have analyzed the distribution of copper concentrations, and the effects of anthropogenic inputs, in the components of two forest ecosystems using a comparative approach. Ecosystem components were defined using a ...
A functional trait based approach to understand tropical forest composition and function in a Costa Rican landscape
(CATIE, Turrialba (Costa Rica), 2014)
Quantifying the factors driving tropical forest composition, structure and function is a continuous area of ecological research. Recently, novel approaches have enabled research
questions on this topic to be addressed not ...
A parallel approach of COFFEE objective function to multiple sequence alignment
(2015-09-21)
The computational tools to assist genomic analyzes show even more necessary due to fast increasing of data amount available. With high computational costs of deterministic algorithms for sequence alignments, many works ...
A unified approach to the study of sums, products, time-aggregation and other functions of ARMA processes
(John Wiley & Sons Ltd, 1984)
Conditions under which sums, products and time-aggregation of ARMA processes follow ARMA models are derived from a single theorem. This characterizes these processes in terms of difference equations satisfied by their ...
A nonparametric bayesian approach for modeling and comparison of functional data
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Estatística - PIPGEsCâmpus São Carlos, 2022-09-02)
The current advances of technology provides, among other things, several ways of collecting
data, which enlarges the possibility of studying new phenomena. Researches focused on studying
the functional relation between ...
Entropy Measures for Stochastic Processes with Applications in Functional Anomaly Detection
(Molecular Diversity Preservation International, 2018-01)
We propose a definition of entropy for stochastic processes. We provide a reproducing kernel Hilbert space model to estimate entropy from a random sample of realizations of a stochastic process, namely functional data, and ...
Managerial styles of small business owners: a study based on the organizational life cycle and on concepts concerning managers' functions and roles
(Fund Escola Comercio Alvares Penteado-fecap, 2015-07-01)
Objective - To identify the managerial styles of small business managers at every stage of the organizational life cycle, considering managers' work, approaches to process and roles. Methodology - This research was considered ...
