Design of a CMG for underwater robots
(2011)
In this paper we present a Control Moment Gyroscope (CMG) for underwater robots. This is a single gimbal CMG with pyramid type configuration. This device has a modular design and is self-contained (i.e., all mechanical and ...
Extension of the B3LYP-dispersion-correcting potential approach to the accurate treatment of both inter-and intra-molecular interactions
(2013)
We recently demonstrated that dispersion-correcting potentials (DCPs), which are atom-centered Gaussian-type functions that were developed for use with B3LYP (Torres and DiLabio in J Phys Chem Lett 3:1738-1744, 2012), ...
Modeling and control of a small hydro-power plant for a DC microgrid
(Elsevier Ltd, 2020)
This paper presents the modeling and control of a small hydro-power plant (SHP) for a DC microgrid based on passivity theory. The SHP is made up of a turbine, a permanent magnet synchronous generator (PMSG), a voltage ...
Women's perceived risk of sexual harassment in a Bus Rapid Transit (BRT) system: The case of Barranquilla, Colombia
(Elsevier Ltd, 2019)
Background: Sexual harassment in public transportation is a growing concern, particularly among women. Over the years, there have been several programs and policies to mitigate sexual harassment while using public transport. ...
Density-functional theory with dispersion-correcting potentials for methane: Bridging the efficiency and accuracy gap between high-level wave function and classical molecular mechanics methods
(2013)
Large clusters of noncovalently bonded molecules can only be efficiently modeled by classical mechanics simulations. One prominent challenge associated with this approach is obtaining force-field parameters that accurately ...
Leveraging speculative architectures for runtime program validation
(2013)
Program execution can be tampered with by malicious attackers through exploiting software vulnerabilities. Changing the program behavior by compromising control data and decision data has become the most serious threat in ...
Blind restoration of retinal images degraded by space-variant blur with adaptive blur estimation
(2013)
Retinal images are often degraded with a blur that varies across the gield view. Because traditional deblurring algorithms assume the blur to be space-invariant they typically fail in the presence of space-variant blur. ...
Exact relativistic models of thin disks around static black holes in a magnetic field
(2014)
The exact superposition of a central static black hole with surrounding thin disk in presence of a magnetic field is investigated. We consider two models of disk, one of infinite extension based on a Kuzmin-Chazy-Curzon ...
Relaxed convex model for optimal location and sizing of DGs in DC grids using sequential quadratic programming and random hyperplane approaches
(Elsevier Ltd, 2020)
This report addresses the problem of optimal location and sizing of constant power sources (distributed generators (DGs)) in direct current (DC) networks for improving network performance in terms of voltage profiles and ...
Application of genetic algorithm to job scheduling under ergonomic constraints in manufacturing industry
(Springer Verlag, 2019)
This research proposes a mathematical model of the problem of job rotation considering ergonomic aspects in repetitive works, lifting tasks and awkward postures in manufacturing environments with high variability. The ...
