Frame retransmission using a modified VST-TDMA access protocol in Picocell/WPAN
(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 ...
Laser scanner based heading angle and distance estimation
(03/17/2013)
Towards autonomous vehicle navigation the problem of guidance is a major difficulty faced by fully autonomous vehicle. This paper proposes a new method to estimate the heading angle for safe autonomous navigation purpose. ...
ROBOCLIMBER: Control System Architecture
(07/01/2004)
The paper shows the complete system architecture of a walking and climbing robot developed to make slope consolidation, where heavy duty equipment is employed for drilling up to 20m holes. ROBOCLIMBER a quadruped robot ...
Characterization of the degradation process of lithium-ion batteries when discharged at different current rates
(05/08/2018)
The use of energy storage devices, such as lithium-ion batteries, has become popular in many different domains and applications. Hence, it is relatively easy to find literature associated with problems of battery state-of-charge ...
Stairway tracking based on automatic target selection using directional filters
(02/09/2011)

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 ...
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 ...
