Short-term rainfall time series prediction with incomplete data
(2015)
In order to predict short-term times series with
incomplete data, a proposed approach is presented based on the
energy associated of series. A benchmark of rainfall time series
and Mackay Glass (MG) samples are used. ...
Effects of native plants extracts from Córdoba Argentina over foraging activity of the cutting ant Acromyrmex lundi (Guérin)
(2013)
In the search for new alternatives for insect pest management, natural products from plants are an option currently studied for being substances of low toxicity and biodegradable. The leaf-cutting ant Acromyrmex lundi is ...
Fire frequency effects on soil and pollinators: what shapes sexual plant reproduction?
(Springer, 2017-12)
Increased fire frequency can significantly erode both soil properties and plant–pollinator interactions affecting plant reproductive success but they have seldom been assessed simultaneously. Here, we evaluate soil properties, ...
Suffusion in compacted loessial silts. Interaction with granular filters
(2013)
Loess soils, which occupies much of central Argentina, is characterized by its high sensitivity to change in moisture. This condition categorized loess structure as internally unstable soil. Despite this ...
A 6-bit 2GS/s CMOS Time-Interleaved ADC for Analysis of Mixed-Signal Calibration Techniques
(2014)
A 6-bit 2-GS/s time interleaved (TI) successive approximation register (SAR) analog-to-digital converter (ADC) is designed and fabricated in a 0.13 μm CMOS process. The architecture uses 8 time-interleaved track-and-hold ...
A new approach to segmentation of remote sensing images with hidden markov models
(2014)
In this work, we present a new segmentation algorithm for remote sensing images based on two-dimensional Hidden Markov Models (2D-HMM). In contrast to most 2D-HMM approaches, we do not use Viterbi Training, instead we ...
Crossing regions for supersonic cones
(2014)
The original study of a conical body of circular cross section at zero angle of attack inside a supersonic flow was developed by Taylor & Maccoll 1933, see [1]. After this year a large amount of numerical and perturbation ...
Yeasts as biocatalysts in the stereoselective reduction of acetophnone
(2015)
The asymmetric reduction of prochiral ketones represents a pivotal transformation for the
production of chiral alcohols. Several of them are considered as key starting materials in obtaining
of pharmaceuticals. Nowadays, ...
Minor Street Gaps and Capacity at Unsignalized Intersections in Argentina
(2012)
Capacity analysis for two way stop controlled (TWSC) intersections is mainly based on headway acceptance theory. Critical headways and follow up times are fundamental parameters in capacity estimation. Both factors clearly ...
Algorithm model and execution based on Petri Nets in an heterogeneous parallel computer
(2014)
Multicore - MultiGPU systems are frequently used in supercomputers design. The heterogeneity between both types of processors is a source of problems for the parallel programming: disparity in processing throughput and ...
