Frame retransmission using a modified VST-TDMA access protocol in Picocell/WPAN
(2017 IEEE 9th Latin-American Conference on Communications (LATINCOM)2017 IEEE 9th Latin-American Conference on Communications (LATINCOM), 12/28/2017)
The VST-TDMA access protocol has shown to have many advantages over existing protocols in centralized (star) wireless network architectures. As most data-link layer protocols, it does not have a recovery feature as data ...
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)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 ...
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 ...
Spatio-temporal probabilistic modeling based on Gaussian mixture models and neural gas theory for prediction of criminal activity
(Annual Conference of the Prognostics and Health Management Society 2017Annual Conference of the Prognostics and Health Management Society 2017, 2017-08-18)
Criminal risk models are used to assist security forces both in the identification of zones with high of criminal activity for better resource allocation and prediction of future criminal events for the prevention of new ...
Modelling the degradation process of lithium-ion batteries when operating at erratic state-of-charge swing ranges
(2017 4th International Conference on Control, Decision and Information Technologies (CoDIT)2017 4th International Conference on Control, Decision and Information Technologies (CoDIT), 11/09/2017)
Manufacturers of lithium-ion batteries inform capacity degradation for regular, symmetrical charge/discharge cycles, which is clearly problematic in real life applications where charge/discharge cycles are hardly regular. ...
Electric Bicycle Energy Management Given an Elevation Traveling Profile
(Annual Conference of the Prognostics and Health Management Society 2017Annual Conference of the Prognostics and Health Management Society 2017, 2017-09-06)
This research proposes a method for energy management in electric bicycles with Lithium-Ion batteries. This method optimizes the way energy is consumed to maximize the rider’s comfort, subject to constraints on the battery ...
SoC control for improved battery life and throughput performance under VST-TDMA
(IETIET, 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 ...
Panama Metro Bus System and Metro Line 1: An externalities analysis of CO2 emissions spectre
(2017-07)
In recent years there is has been a need to reduce traffic congestion with the objective of contributing to the reduction of CO2 emissions or air pollution. This argument could be seen as a new tariff or tax to make society ...
Perspectiva de las externalidades socio económicas de la línea 1 del metro de Panamá en la productividad urbana
(2017-02)
En este trabajo de investigación se analizan algunas de las externalidades de corte económico generadas por la Línea 1 del Metro en la Ciudad de Panamá. La congestión vehicular de las urbes produce pérdidas anuales ...
Ahorro en tiempos de viajes: externalidad socio económicas de la línea 1 del metro de Panamá en la productividad urbana
(2017-03)
La congestión vehicular de las urbes produce pérdidas anuales en millones de dólares, afectando sensitivamente la productividad. Los beneficios sociales de los sistemas masivos de transporte público producen un impacto ...
