A long-term field study on the adoption of smartphones by children in Panama
(MobileHCI '14 Proceedings of the 16th international conference on Human-computer interaction with mobile devices & service, 09/23/2014)
Computing technology is currently adopted in emerging countries. Especially mobile phones and smart phones become widely used - with a much higher penetration than traditional computers. In our work we investigate how ...
Lithium-ion battery pack arrays for lifespan enhancement
(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 ...
Low power consumption silicon photonics tuning filters based on compound microring resonators
(03/14/2013)
Scalable integrated optics platforms based on silicon-on-insulator allow to develop optics and electronics functions on the same chip. Developments in this area are fostered by its potential as an I/O technology that can ...
SoC control for improved battery life and throughput performance under VST-TDMA
(IET, 02/09/2017)
Energy independence is a wireless device quality that demands the utmost exigency. Energy harvesting devices (EHD) alleviate the energy constraints demanded by these nodes and with the use of protocols, such as variable ...
Sagnac loop in ring resonators for tunable optical filters
(08/01/2005)
General filter architecture using co-and counterpropagation signals are studied. A specific configuration based on a Sagnac loop within a ring resonator is analyzed. Novel tuning, apart from conventional tuning,is achieved ...
A Web and Mobile Applications for Self-control of Patient Blood Pressure Through Mobiles and Biometrics Devices
(International Conference on Ubiquitous Computing and Ambient Intelligence, 10/07/2017)
In this article, we want to present a platform that allows the integration of different applications for the follow-up of patients with chronic diseases. We are developing two elements: the first one, is a mobile application ...
Advances in the adsorptive particulate flotation process
(09/18/2003)
The removal of contaminants from liquid effluents by the adsorptive particulate flotation (APF) process, including new adsorbents and flotation devices, are reported. Herein, contaminants are adsorbed (and/or absorbed) ...
Virtual world interaction
(04/04/2014)
The research paper describes the development of a user friendly 3D virtual world. For the research, we modeled building number 3 of the Technological University of Panama, Victor Levi Sasso Campus.
For the virtual world ...
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 ...
State-of-charge estimation to improve energy conservation and extend battery life of wireless sensor network nodes
(2017 Ninth International Conference on Ubiquitous and Future Networks (ICUFN), 07/27/2017)
Wireless sensor networks are pervasive systems that continuously demonstrate increase in growth by branching into diverse applications. The state of charge is an indicator that conveys the amount of energy available in the ...
