Refuse production in leaf-cutting ants (Hymenoptera: Formicidae) and its relationship with leaf harvest
(Taylor & Francis Ltd, 1996-05-01)
We examined the relationship between fungal refuse production and vegetation input in a laboratory colony of the leaf-cutting ant Acromyrmex coronatus. We found only a strong 6-day time-delay in the production of refuse ...
Double sampling X̄ control chart for a first order autoregressive process
(2008-09-01)
In this paper we propose the Double Sampling X̄ control chart for monitoring processes in which the observations follow a first order autoregressive model. We consider sampling intervals that are sufficiently long to meet ...

Exploratory and confirmatory spatial data analysis tools in transport demand modeling
(2007-01-01)
The main goal of this paper is to discuss a method for the definition of spatial dependence indicators and their inclusion as variables into transportation demand models. The method is based on ESDA (Exploratory Spatial ...
Gráficos de controle para dados do tipo taxas e proporções autocorrelacionados
(Universidade Federal de Santa MariaBREngenharia de ProduçãoUFSMPrograma de Pós-Graduação em Engenharia de Produção, 2016-03-28)
This work discusses one of the areas for quality improvement, defined as statistical process
control (SPC). One of the most used tools in SPC is the control chart, which is used to
monitor parameters of a process. In ...
