Rectangular Form Optimal Power Flow by Interior-Point Methods
, 1997
"... : The solution of an optimal power flow (OPF) problem in rectangular form by an interior-point method (IPM) for nonlinear programming is described. When formulated in rectangular form, some OPF variants have quadratic objective and quadratic constraints. Such quadratic features allow for ease of ma ..."

of matrix setup and inexpensive incorporation of higher-order information in a predictor-corrector procedure that improves the IPM performance. Besides presenting an OPF in rectangular form, the paper describes the derivation of the IPM from a general nonlinear programming problem, and discusses major
2008 Taiwan-Polish Joint Seminar on Coastal Protection C-27 VOF for the Free Surface Flows of Breaking Waves
"... A numerical model for simulating breaking waves on a sloping bed was developed. A RANS (Reynolds Averaged Navier-Stokes) based model and the embedding method for bluff body flows on a solid object were employed by taking account of the fully nonlinear, viscous and turbulent effects on the wave break ..."

Computational Modeling of FRP Reinforced Cementitious Beams
"... In the present paper, a one-dimensional elastoplastic-damage model for the analysis of the mechanical response of beams consti-tuted by cementitious materials, i.e., concrete or masonry, strength-ened by fiber reinforced polymers (FRP), is developed. The analysis is performed for a typical section, ..."
