Atrial fibrillation subtypes classification using the General Fourier-family Transform

Ortigosa, Nuria; Cano, O.; Ayala Gallego, Guillermo; Galbis Verdu, Antonio; Fernandez Rosell, Carmen (Elsevier, 2014-04)

Atrial fibrillation patients can be classified into paroxysmal, persistent and permanent attending to the temporal pattern of this arrhythmia. The surface electrocardiogram hides this differentiation. A classification ...
Information retrieval in multimedia databases using relevance feedback algorithms. Applying logistic regression to relevance feedback in image retrieval systems

Zuccarello, Pedro Diego (Universitat Politècnica de València, 2011-10-19)

This master tesis deals with the problem of image retrieval from large image databases. A particularly interesting problem is the retrieval of all images which are similar to one in the user's mind, taking into account ...
Looking for representative fit models for apparel sizing

Vinue, G.; Leon, T.; Alemany Mut, Mª Sandra; Ayala Gallego, Guillermo (Elsevier, 2014-01)

This paper is concerned with the generation of optimal fit models for use in apparel design. Representative fit models or prototypes are important for defining a meaningful sizing system. However, there is no agreement ...
MATHEMATICAL MODELLING AND PARENTAGE ANALYSIS OF HYBRID ZONES

Palero Pastor, Ferran Eustaquio (Universitat Politècnica de València, 2011-12-19)

The theoretical framework behind the mathematical analysis of clines in nature is reviewed. Then, a simplified version of these models implemented in Mathematica is presented. Finally, parentage analysis methods are tested ...
Modeling of female human body shapes for apparel design based on cross mean sets

Domingo, J.; Ibanez, M.V.; Simo, A.; Dura, E.; Ayala Gallego, Guillermo; Alemany Mut, Mª Sandra (Elsevier, 2014-10-15)

This paper is concerned with a method to build prototypes of human bodies that can be used for apparel design. One of the most important issues in the apparel development process is to define a sizing system to provide a ...
Relationship between neck kinematics and neck dissability index. An approach based on functional regression

Aragón-Basanta, Elisa; Venegas, William; Ayala, Guillermo; Page Del Pozo, Alvaro Felipe; Serra-Añó, Pilar (Nature Publishing Group, 2024-01-02)

[EN] Numerous studies use numerical variables of neck movement to predict the level of severity of a pathology. However, the correlation between these numerical variables and disability levels is low, less than 0.4 in the ...
Statistical tools and control of internal lubricant content of inhalation grade HPMC capsules during manufacture

Ayala, Guillermo; Diez, Fernando; Gasso Matoses, María Teresa; Jones, Brian E.; Martin-Portugues, Rafae; Ramiro-Aparicio, Juan (Elsevier, 2016-04)

The internal lubricant content (ILC) of inhalation grade HPMC capsules is a key factor to ensure good powder release when the patient inhales a medicine from a dry powder inhaler (DPI). Powder release from capsules has ...
Variation of P-wave indices in paroxysmal atrial fibrillation patients before and after catheter ablation

Ortigosa, Nuria; Ayala, Guillermo; Cano, Óscar (Elsevier, 2021-04)

[EN] The effects of pulmonary vein isolation in the surface electrocardiogram of patients with paroxysmal atrial fibrillation are analyzed in this paper using non-invasive markers for early detection of the arrhythmia ...
