Weighted parsimony phylogeny of the family Characidae (Teleostei: Characiformes)
(Wiley Blackwell Publishing, Inc, 2009-07)
The family Characidae, including more than 1000 species, lacks a phylogenetic diagnosis, with many of its genera currently considered as incertae sedis. The aims of the present study are to propose a phylogenetic diagnosis ...
A transmission power self-optimization technique for wireless sensor networks
(2012)
Wireless sensor networks (WSNs) are generally used to monitor hazardous events in inaccessible areas. Thus, on one hand, it is preferable to assure the adoption of the minimum transmission power in order to extend as much ...
La actividad física como variable diferenciadora en la autoeficacia y el optimismo en trabajadores del sector retail
(Universidad Católica de Pereira, 2020-07-10)
La actividad física está asociada a estilos de vida saludable y al bienestar físico y psicológico. La autoeficacia y el optimismo benefician a las organizaciones. Este estudio examina el papel diferenciador de la actividad ...
Self-Organized Hybrid Wireless Sensor Network for Finding Randomly Moving Target in Unknown Environment
Unknown target search, in an unknown environment, is a complex problem in Wireless Sensor Network (WSN). It does not have a linear solution when target’s location and searching space is unknown. For the past few years, ...
A self-learning simulated annealing algorithm for global optimizations of electromagnetic devices
(Institute of Electrical and Electronics Engineers (IEEE), 2014)
Relationship between age, category and experience with the soccer referee's self-efficacy
Soccer referees (SRs) encounter stressful situations during competitions and sometimes even outside them, which may affect their decision making. Therefore, it is important that they possess or acquire optimal levels of ...
Statistical Simplex Method for Experimental Design in Process Optimization
(American Chemical Society, 2005-11)
Experimental optimization with scarce and noisy process data is a key issue in laboratory automation for faster chemical process research and development, real-time process optimization, and the ability to embed a learning ...
Full-duplex amplify-and-forward relays with optimized transmission power under imperfect transceiver electronics
(Springer, 2017-12)
In-band full-duplex (FD) relays are useful for extending coverage areas and increasing overall throughput in wireless networks. The main technical difficulty hindering their implementation and use is their inherent ...
A Model of reputation with self-revelation choice
(2020-03-25)
This paper seeks to show how firms act in an environment where certification is available and shocks that reveal its quality can occur at any moment. We study the optimal timing of certification and the optimal price (in the ...
