A Summary of the Developmental Trajectory of Executive Functions from Birth to Adulthood
(Springer Nature Switzerland AG, 2021)
Executive functions (EFs) refer to cognitive control abilities that can sustain goal-directed behavior within complex contexts or changing contingencies. This cognitive functioning domain involves abilities such as inhibitory ...
Robust-control-based controller design for a mobile robot
(Springer, 2008-10)
The control of a mobile robot using a linear model with uncertainty for design purposes is investigated. The uncertainty arises from the variation of the operation point of the mobile robot. Robust Control Theory is used ...
Time-optimal trajectory planning for industrial robots with end-effector acceleration constraints
(Universidad de los AndesMaestría en Ingeniería MecánicaFacultad de IngenieríaDepartamento de Ingeniería Mecánica, 2023-01-14)
The implementation of manipulator robots has become indispensable in various industries, enabling efficient performance of complex tasks. Swift and efficient movement of these robots is essential to maximize productivity. ...
Strategies for plane change of Earth orbits using lunar gravity and derived trajectories of family G
(Springer, 2009-04-01)
The dynamics of the circular restricted three-body Earth-Moon-particle problem predicts the existence of the retrograde periodic orbits around the Lagrangian equilibrium point L1. Such orbits belong to the so-called family ...
Evolution of the short-fiber technological trajectory in Brazil's pulp and paper industry: the role of firm-level innovative capability-building and indigenous institutions
(Elsevier Science Bv, 2016-03)
Despite the growing interest in innovation in the pulp and paper industry (PPI) from strategic management and institutional standpoints, little empirical research exists on the role of firms' technological capabilities and ...
Swarm control designs applied to a micro-electro-mechanical gyroscope system (MEMS)
(2010-12-01)
This paper analyzes the non-linear dynamics of a MEMS Gyroscope system, modeled with a proof mass constrained to move in a plane with two resonant modes, which are nominally orthogonal. The two modes are ideally coupled ...
Evaluation of two wheelchair hand rim models: contact pressure distribution in straight line and curve trajectories
(2019-01-01)
Manual wheelchairs are essential for people with disabilities or limited mobility. However, manual propulsion causes biomechanical loads, including contact pressures on the palms of the hands. The hand rim design has ...
