Oxidative stress and quality of life in elderly patients with obstructive sleep apnea syndrome: are there differences after six months of Continuous Positive Airway Pressure treatment?
(Faculdade de Medicina / USP, 2012-01-01)
OBJECTIVES: This study evaluated the effect of Continuous Positive Airway Pressure treatment on oxidative stress parameters and the quality of life of elderly patients with obstructive sleep apnea syndrome. METHODS: In ...
Study of alternative schemes for the parameterization step of the continuation power flow method based on physical parameters, part II: Performance evaluation
(Taylor & Francis Inc, 2003-12-01)
New parameterization schemes have been proposed by the authors in Part I of this paper. In this part these new options for the parameterization of power flow equations are tested, namely, the total power losses (real and ...
An efficient geometric parameterization technique for the continuation power flow
(Elsevier B.V., 2007-01-01)
Continuation methods have been shown as efficient tools for solving ill-conditioned cases, with close to singular Jacobian matrices, such as the maximum loading point of power systems. Some parameterization techniques have ...
Mixed integer quadratically-constrained programming model to solve the irregular strip packing problem with continuous rotations
The irregular strip packing problem consists of cutting a set of convex and non-convex two-dimensional polygonal pieces from a board with a fixed height and infinite length. Owing to the importance of this problem, a large ...
Geometric Parameterization Technique for Continuation Power Flow Based on Quadratic Curve
The electricity sector, especially in emerging countries, has experienced several transformations, mainly resulting from the increase of electricity demand. This encourages more investment in the generation sector and ...
