Origin and implications of orbital-induced sedimentary cyclicity in Pliocene well-logs of the Western Mediterranean
(Elsevier, 2018)
The climatic origin of astronomically induced sedimentary cycles in the Mediterranean and adjacent areas during the late Neogene and Quaternary remains puzzling; as cycles have been linked to concomitant but seasonally ...
Classification of petroleum well drilling operations using Support Vector Machine (SVM)
(2007-12-01)
During the petroleum well drilling operation many mechanical and hydraulic parameters are monitored by an instrumentation system installed in the rig called a mud-logging system. These sensors, distributed in the rig, ...

Generalized log-gamma regression models with cure fraction
(SPRINGER, 2009)
In this paper, the generalized log-gamma regression model is modified to allow the possibility that long-term survivors may be present in the data. This modification leads to a generalized log-gamma regression model with ...
Dynamic entropy-compressed sequences and full-text indexes
(SPRINGER-VERLAG BERLIN, 2006)
Given a sequence of n bits with binary zero-order entropy H-o, we present a dynamic data structure that requires nH(o) + o(n) bits of space, which is able of performing rank and select, as well as inserting and deleting ...
Classification of petroleum well drilling operations with a hybrid particle swarm/ant colony algorithm
(2009-11-09)
This paper describes an investigation of the hybrid PSO/ACO algorithm to classify automatically the well drilling operation stages. The method feasibility is demonstrated by its application to real mud-logging dataset. The ...

An alphabet-friendly FM-index
(SPRINGER-VERLAG BERLIN, 2004)
We show that, by combining an existing compression boosting technique with the wavelet tree data structure, we are able to design a variant of the FM-index which scales well with the size of the input alphabet Sigma. The ...
Dynamic Entropy-Compressed Sequences and Full-Text Indexes
(ASSOC COMPUTING MACHINERY, 2008-06)
Given a sequence of n bits with binary zero-order entropy
H0, we present a dynamic data structure that requires nH0 + o(n) bits
of space, which is able of performing rank and select, as well as inserting
and deleting ...
