Water Quality Evaluation of the Cabra River Using Biological Indicators
(2019 7th International Engineering, Sciences and Technology Conference (IESTEC)2019 7th International Engineering, Sciences and Technology Conference (IESTEC), 2019-10-09)
The objective of this study was to evaluate the water quality of the Cabra River through the use of aquatic macroinvertebrates implementing the EPT and BMWP/Pan indexes. The diversity of orders and families of macroinvertebrates ...
Automatic generation of ETL processes from conceptual models
(11/06/2009)
Data warehouses (DW) integrate different data sources in order to give a multidimensional view of them to the decision-maker. To this aim, the ETL (Extraction, Transformation and Load) processes are responsible for extracting ...
Informational kiosk interactive
(08/21/2013)
This paper presents the implementation of the System user interface KINFO-UTP using video game technology. We discuss the cataloging facilities building # 3 of the Technological University of Panama, which are displayed ...
Semi-supervised 3D object recognition through CNN labeling
(04/01/2018)
Despite the outstanding results of Convolutional Neural Networks (CNNs) in object recognition and classification, there are still some open problems to address when applying these solutions to real-world problems. Specifically, ...
Assessing usability in dof: an Activity for children with speech disorders
(IADIS International Conference e-Society 2017IADIS International Conference e-Society 2017, 06/01/2017)
This paper presents the findings of an empirical study of a prototype for children with speech disorders. --- the purpose of this work was to evaluate the interaction process of children on the Dice of Phoneme DoF (DoF) ...
Tunable optical filters using compound ring resonators for DWDM
(07/28/2003)
The device is based on a loop mirror in a ring resonator. The loop mirror allows tuning by changing the coupling coefficient of a directional coupler. The loop mirror is implemented using a Sagnac configuration to have the ...

The prospect of using humanoid robots in practical applications attracts an important research effort and the latest steps forward in robot technology show many remarkable achievements where design aspects, control systems ...
Scintillometer networks for calibration and validation of energy balance and soil moisture remote sensing algorithms
(05/07/2007)
Accurate estimation of sensible and latent heat fluxes as well as soil moisture from remotely sensed satellite images poses a great challenge. Yet, it is critical to face this challenge since the estimation of spatial and ...
Lithium-ion battery pack arrays for lifespan enhancement
(2017 CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON)2017 CHILEAN Conference on Electrical, Electronics Engineering, Information and Communication Technologies (CHILECON), 12/21/2017)
Depending on the application, power and energy requirements may differ significantly and, most likely, a single lithium-ion cell will not suffice. Battery packs offer cell interconnections that allow to obtain several ...
Characterization of Biochar from Rice Hulls and Wood Chips Produced in a Top-Lit Updraft Biomass Gasifier
(2016-01-01)
The objective of this study was to characterize biochar produced from rice hulls and wood chips in a top-lit updraft gasifier. Biochar from four airflows (8, 12, 16, or 20 L min-1) and two insulation conditions (not insulated ...
