Temporal analysis of 911 emergency calls through time series modeling
(Springer, 2020)
We present two techniques for modeling time series of emergency events using data from 911 emergency calls in the city of Cuenca-Ecuador. We study state-of-the-art methods for time series analysis and assess the benefits ...
Emergence prediction of common Groundsel (Senecio vulgaris)
(WEED SCI SOC AMER, 2008)
Common groundsel is an important weed of strawberry and other horticultural crops. Few herbicides are registered for common groundsel control in such crops, and understanding and predicting the timing and extent of common ...
A comparative study between non-linear regression and artificial neural network approaches for modelling wild oat (Avena fatua) field emergence
(Cambridge University Press, 2013-01)
Non-linear regression (NLR) techniques are used widely to fit weed field emergence patterns to soil microclimatic indices using S-type functions. Artificial neural networks (ANNs) present interesting and alternative ...
Weed Emergence Models
(Springer Nature Switzerland AG, 2020)
Weed emergence models are practical tools that aim to describe the dynamics of emergence in the field. Such models can be conceptualized from two main perspectives: a reductionist/mechanistic approach and an empirical ...

Time-series analysis of ambient PM2.5 and cardiorespiratory emergency room visits in Lima, Peru during 2010-2016.
(Springer, 2019)
Introduction: There have been no time-series studies of air pollution in Peru. Here we evaluate the effect of ambient PM2.5 on emergency room (ER) visits in Lima. Methods :We estimated daily PM2.5 levels at a 1 km2 resolution ...
Dinamicity and unpredictability of emerging markets: an implementation of Goetzamnn and Jorion (1999)
(2015-02-27)
This research is to be considered as an implementation of Goetzmann and Jorion (1999). In order to provide a more realistic scenario, we have implemented a Garch (1,1) approach for the residuals of returns and a multifactor ...
Modeling Avena fatua seedling emergence dynamics: An artificial neural network approach
(Elsevier, 2012-08-11)
Avena fatua is an invasive weed of the semiarid region of Argentina. Seedling emergence patterns are very irregular along the season showing a great year-to-year variability mainly due to a highly unpredictable precipitation ...
