A Practical and Simple Graphic Model to Appraise the Occurrence of Dry Spells in the Humid TropicsTítulo en español
(University of Puerto Rico Mayagüez Campus Agricultural Experiment Station, 1981)
Geomagnetic storm occurrence and their relation with solar cycle phases
(Amer Geophysical Union, 2021)
Using a time series of geomagnetic storm events between 1957 and 2019, obtained by selecting storms where Dst<-50 nT, we have analyzed the probability of occurrence of moderate, intense, and severe events. Considering that ...
Probabilidade de ocorrência de temperaturas máximas e mínimas mensais prejudiciais e favoráveis aos cultivos agrícolas em Minas Gerais, Bahia e Rio Grande do Sul
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em AgronomiaCentro de Ciências Rurais, 2020-11-27)
In the face of speculation about climate change, global warming, impact on the environment and agriculture, the study of the probability of the occurrence of harmful and environment-friendly maximum and minimum air ...
Probabilidade de ocorrência de deficiência hídrica na cultura do girassol na região central do Rio Grande do Sul
(Universidade Federal de Santa MariaBRAgronomiaUFSMPrograma de Pós-Graduação em Agronomia, 2012-03-09)
In Brazil over recent years the interest increased on the sunflower cultivation. Sunflower yield can be
decreased by water deficit. To solve this problem, is necessary to calculate the probable water deficit
in critical ...
Approximations of δ -record probabilities in i.i.d. and trend models
(Springer, 2023)
We study the probability of occurrence of -records in a model
with linear trend. While this probability has been studied in the iid case,
the existence of a trend makes its analysis much more involved. Asymptotic
properties ...
Anomalous night-time peaks in diurnal variations of NmF2 close to the geomagnetic equator: A statistical study
(Elsevier, 2007-11)
We present a study of anomalous night-time NmF2 peaks, ANNPs, observed by the La Paz, Natal, Djibouti, Kodaikanal, Madras, Manila, Talara, and Huancayo–Jicamarca ionosonde stations close to the geomagnetic equator. It is ...
Incorporating the uncertainty in geological boundaries into mineral resources evaluation
(2007)
Geological modelling is a key step prior to grade estimation in a mineral deposit and consists of a deterministic partitioning of the deposit into sub-domains called 'geological units', each with relatively homogeneous ...
Analysis and assessment risk due sliding mine waste facilities located in the north of PeruAnálisis y evaluación de riesgo por deslizamiento de un depósito de desmonte de mina ubicado en el norte del Perú
(Universidad Nacional Mayor de San Marcos, Facultad de Ingeniería Geológica, Minera, Metalúrgica y Geográfica, 2022)
