Determinación de la presión sonora radiada por pistones circulares y anillos no planos usando un método numérico simplificado

Alba Fernández, Jesús; Arenas, J.P.; Rey Tormos, Romina María del (Elsevier, 2014-10)

[EN] Although the study of the sound pressure radiation from membranes and plates is not new, current and future applications have produced a large body of recent research in the field. Several works have been published ...
Drug-tubulin interactions interrogated by transient absorption spectroscopy

Bosca Mayans, Francisco; Sastre Navarro, German Ignacio; Andreu, José María; Jornet, David; Tormos Faus, Rosa Esperanza; Miranda Alonso, Miguel Ángel (Royal Society of Chemistry, 2015)

[EN] Colchicine (COL) is a bioactive molecule with antitumor properties. When COL binds to tubulin (TU), it inhibits microtubule assembly dynamics. We have investigated COL-TU interactions using laser flash photolysis (LFP) ...
Estudio de los parámetros y diseño de una antena de apertura circular

Gómez-Torrijos Pérez, Daniel Antonio (Universitat Politècnica de València, 2017-11-21)

[EN] This project studies the radiation parameters in a slot ring antenna, and the variations produced in those paremeters by changin the size of the antenna and slot. First of all, a correlation is stablished between the ...
Invertibility in rings of the commutator ab-ba, where aba=a and bab=b

Benítez López, Julio; Liu, Xiaoji; Rakocevic, Vladimir (Taylor & Francis, 2012)

Let R be a ring and a, b is an element of R satisfy aba = a and bab = b. We characterize when ab - ba is invertible. This study is specialized when R has an involution and when b is the Moore-Penrose inverse of a.
Preliminary Desing and Optimization of a Power Gearbox for the Ultrafan TM Geared Engine

Valbuena Antón, Miguel Ángel (Universitat Politècnica de València, 2016-03-08)

The need for a more efficient and environmentally-friendly aviation has led to the development of low-emission, low-noise engines. Increasing the bypass ratio is known to be an effective solution in order to reduce the ...
Some additive results on Drazin inverse

Liu, X.J.; Qin, X.L.; Benítez López, Julio (Springer Verlag (Germany), 2015-12)

In this paper, we investigate additive results of the Drazin inverse of elements in a ring R. Under the condition ab = ba, we show that a + b is Drazin invertible if and only if aa^D(a+b) is Drazin invertible, where the ...
Syncronization of microresonator's based chaotic frequency combs

Moreno Gallego de la Sacristana, David (Universitat Politècnica de València, 2022-10-15)

[ES] La sincronización se manifiesta en la naturaleza como una sincronización espectral o temporal de osciladores no lineales acoplados. En el campo de la fotónica, se han propuesto peines de frecuencias basados en ...
The diamond partial order in rings

Lebtahi Ep-Kadi-Hahifi, Leila; Patricio, Pedro; Thome, Néstor (Taylor & Francis: STM, Behavioural Science and Public Health Titles, 2014)

In this paper we introduce a new partial order on a ring, namely the diamond partial order. This order is an extension of a partial order defined in a matrix setting in [J.K. Baksalary and J. Hauke, A further algebraic ...
The special elements in a ring related to the Drazin inverses

Lebtahi Ep-Kadi-Hahifi, Leila; Patrício, Pedro; Thome, Néstor (Taylor & Francis: STM, Behavioural Science and Public Health Titles, 2013)

In this article, the existence of the Drazin (group) inverse of an element a in a ring is analysed when amk ¼ kan , for some unit k and m, n 2 N. The same problem is studied for the case when a* ¼ kamk1 and for the {k, ...
VÍDEO STOP MOTION SOBRE EL PROYECTO ESCENOGRÁFICO DE LA OBRA EL SUEÑO DE LA RAZÓN DE ANTONIO BUERO VALLEJO

Alcazar Garcia, Mariano Jose (Universitat Politècnica de València, 2020-07-30)

[ES] El presente proyecto es la realización de un video con la técnica stop motion a partir de los elementos desarrollados para un proyecto escenográfico sobre la obra teatral de Antonio Buero Vallejo, El Sueño de la Razón ...
