Lightning activity in the Southern Coast of Chile
(2014)
Based on eight years of lightning data (from January 2005 to December 2012) from the World Wide Lightning Location Network (WWLLN) we describe the spatial distribution and temporal variability of lightning activity over ...
A Natural Language Instructor for pedestrian navigation based in generation by selection
(Association for Computational Linguistics, 2014)
In this paper we describe a method for developing a virtual instructor for pedestrian navigation based on real interactions between a human instructor and a human pedestrian. A virtual instructor is an agent capable ...
A comparison of preschool and elementary school children learning computer science concepts through a multilanguage robot programming platform
(2015)
This paper describes a school intervention to teach fundamental Computer Science (CS) concepts to 3-11 year old students with a multilanguage robot programming platform (using drag and drop, Python and C++ languages) in ...
Longitudinal gradient-coil with improved uniformity within the volume of interest
(2014)
We present a longitudinal magnetic fieldgradient-coil with optimized uniformity within the volume ofinterest (VOI). The accuracy of the optimization algorithm wasconfronted with measurements of the spatial dependence of ...
Corrosion of steel alloys with ferrite coating
(2015)
The corrosion protection offered by coatings of hexagonal Sr ferrites on steel samples in the presence of chloride was evaluated by electrochemical techniques. Different samples were prepared using Nd-Co doped and un-doped ...
On the robustness of standalone referring expression generation algorithms using RDF data
(2016)
A sub-task of Natural Language Generation (NLG) is the generation of referring expressions (REG). REG algorithms are expected to select attributes that unambiguously identify an entity with respect to a set of distractors. ...
Fault manifestability verification for discrete event systems
(2016)
Fault diagnosis is a crucial and challenging task in the automatic control of complex systems, whose efficiency depends on the diagnosability property of a system. Diagnosability describes the system ability to determine ...
Combining semi-supervised and active learning to recognize minority senses in a new corpus
(2015)
In this paper we study the impact of combining active learning with bootstrapping to grow a small annotated corpus from a different, unannotated corpus. The intuition underlying our approach is that bootstrapping includes ...
Sustainable chemotherapy schedules
(2015)
We used a discrete time version of viabilitytheory in order to study the sustainable therapies againstthe cancer. We assume that the tumor is composed of twosubpopulations, one resistant and the another sensitive. Weconsider ...
Logical characterization of bisimulation for transition relations over probability distributions with internal actions
(2016)
In recent years the study of probabilistic transition systems has shifted to transition relations over distributions to allow for a smooth adaptation of the standard non-probabilistic apparatus. In this paper we study ...
