Advanced form-finding for cable dome structures

LEE, Jaehong; TRAN, Hoang Chi; LEE, Kihak (Editorial Universitat Politècnica de València, 2010-02-24)

A numerical method is presented for form-finding of cable domes. The topology and the types of members are the only information that requires in this form-finding process. Dummy elements are used to transform the cable ...
Application of the singular value and pivoted QR decompositions to reduce experimental efforts in compressor characterization

Tiseira, Andrés-Omar; Pla Moreno, Benjamín; Bares-Moreno, Pau; Aramburu-Orihuela, Alexandra (Elsevier, 2022-11)

[EN] Compressor characterization, either by running experiments in a turbocharger test rig or by detailed CFD modelling, can be expensive and time-consuming. In this work, a novel method is proposed which can be used to ...
Approximating the inverse and the Moore-Penrose inverse of complex matrices

Cordero Barbero, Alicia; Torregrosa Sánchez, Juan Ramón; Zafar, Fiza (John Wiley & Sons, 2019-11-30)

[EN] A parametric family of fourth-order schemes for computing the inverse and the Moore-Penrose inverse of a complex matrix is designed. A particular value of the parameter allows us to obtain a fifth-order method. ...
Generalized inverses estimations by means of iterative methods with memory

Artidiello, Santiago; Cordero Barbero, Alicia; Torregrosa Sánchez, Juan Ramón; Vassileva, María P. (MDPI AG, 2020-01)

[EN] A secant-type method is designed for approximating the inverse and some generalized inverses of a complex matrix A. For a nonsingular matrix, the proposed method gives us an approximation of the inverse and, when the ...
Inelastic nonlinear analysis of beam with under-tension cables

LEE, Jaehong; PARK, DukKun; KIM, Yeontae; WOO, Sungwoo (Editorial Universitat Politècnica de València, 2009-12-15)

For long span structures, the size of the structural members should be determined by considering the esthetic view. As a result, the slenderness ratio of members is increased and the structures may be suffered from ...
Using the GSVD and the lifting technique to find {P; k+ 1} reflexive and anti-reflexive solutions of AXB = C

Herrero Debón, Alicia; Thome, Néstor (Elsevier, 2011-07)

The generalized singular value decomposition (GSVD) and the lifting technique combined with the Kronecker product are exploited to find reflexive and anti-reflexive (with respect to a generalized k+1-reflection matrix P) ...
Ventricular activity morphological characterization: Ectopic beats removal in long term atrial fibrillation recordings

Martínez, A.; Alcaraz, R.; Rieta, J J (Elsevier, 2013-03)

Ectopic beats are early heart beats remarkably different to the normal beat morphology that provoke serious disturbances in electrocardiographic analysis. These beats are very common in atrial fibrillation (AF), causing ...
