Complex modal analysis of a slender vertical rotor by finite elements method
(Inegi-inst Engenharia Mecanica E Gestao Industrial, 2012-01-01)
In this paper, natural frequencies were analyzed (axial, torsional and flexural) and frequency response of a vertical rotor with a hard disk at the edge through the classical modal and complex analysis. The equation that ...
ℋ∞ Static Output Feedback Control Of Discrete-time Markov Jump Linear Systems With Uncertain Transition Probability Matrix
(Institute of Electrical and Electronics Engineers Inc., 2014)
Analysis of the Influence of PSS and IPFC-POD Controllers in Small-Signal Stability Using a Simulated Annealing Algorithm
This work presents an analysis of the influence of Power System Stabilizers and the Interline Power Flow Controller-Power Oscillation Damping set in small-signal stability of electric power systems using a modified Simulated ...
Particle Competition and Cooperation in Networks for Semi-Supervised Learning with Concept Drift
Concept drift is a problem of increasing importance in machine learning and data mining. Data sets under analysis are no longer only static databases, but also data streams in which concepts and data distributions may not ...
Stresses in implant-supported overdentures with bone resorption
(Porto Alegre, 2010)
Objectives: This 3D-finite elements method study evaluated the effect of bone resorption on the stress distribution in overdentures with bone loss surrounding implants and resorption of the distal ridge. Methods: Tridimensional ...
A single-phase single-stage buck-boost inverter intended for low power alternative energy conversion systems: Analysis, design and experimentation
This paper presents the operational analysis of the single-phase integrated buck-boost inverter. This topology is able to convert the DC input voltage into AC voltage with a high static gain, low harmonic content and ...
Minimum energy DP heading control : critical analysis and comparision of different strategies
(Ocean, Offshore and Arctic Engineering DivisionNantes, 2013-06-09)
DP offshore operations require that the vessel reference point is controlled in relation to a fixed reference frame. In some cases, the heading is allowed to change, searching for an adequate angle in which the environmental ...
