A Top-Down Approach for Distribution Loss Evaluation
(Institute of Electrical and Electronics Engineers (IEEE), 2009-10-01)
A methodology, which can be classified as Top-Down, aimed at computing technical losses in distribution systems is proposed. It can be applied to either evaluate part of the network or to analyze the whole distribution ...
Fatigue crack growth of Al 7475 T761 under constant and variable amplitude loading
(Pergamon Press Ltd, 2014)
Passive vibration isolation using axially loaded curved beams
(2011-12-01)
A nonlinear spring element of a vibration isolator should ideally possess high static and low dynamic stiffness. A buckled beam may be a good candidate to fulfil this requirement provided its internal resonance frequencies ...
Effects of specimen geometry and loading mode on crack growth resistance curves of a high-strength pipeline girth weld
(London, 2014-02-11)
This work presents an investigation of the ductile tearing properties for a girth weld made of an API 5L X80 pipeline steel using experimentally measured crack growth resistance curves. Use of these materials is motivated ...
Effects of specimen geometry and mode loading on crack growth resistance curves of X80 pipeline girth welds
(The Chinese Society of Theoretical and Applied MechanicsBeijing, 2013-06-16)
This work presents an investigation of the ductile tearing properties for a girth weld made of an API 5L X80 pipeline steel using experimentally measured crack growth resistance curves. Use of these materials is motivated ...
Dishonest Newton Method Applied in Continuation Power Flow Through a Geometric Parameterization Technique
(2016-01-01)
The electricity sector has gone through several transformations due primarily to increased electricity demand, especially in emerging countries. This encourages more investment in the generation and leads to a growing ...
Parameterization technique for the continuation power flow using the trivial and tangent predictor
(2012-11-01)
This paper presents efficient geometric parameterization techniques using the tangent and the trivial predictors for the continuation power flow, developed from observation of the trajectories of the load flow solution. ...
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 ...
The cone loading test to estimate deformability moduli of a tropical soil
(2013)
The Cone Loading Test (CLT) consists of the execution of a load test on the piezocone probe in conjunction with the CPT test. The CLT yields the modulus ECLT, a parameter that can be used in the estimative of foundation ...
