feature extraction is a main step in all perceptual image hashing schemes in which robust features will led to better results in perceptual robustness. simplicity, discriminative power, computational efficiency and robustness to illumination changes are counted as distinguished properties of local binary pattern features. in this paper, we investigate the use of local binary patterns for percep...

L’analisi frequentistica delle occorrenze, tipica dei modelli di ranking di information retrieval, può essere integrata con l’analisi della spaziatura fra le occorrenze di una singola parola, mutuata dallo studio dei livelli di energia dei sistemi statistici di quanti disordinati. Queste due aree di ricerca sono fortemente interrelate, perché entrambe hanno l’obiettivo di assegnare dei pesi di ...

an analytical nonlinear stress-strain model and a microscopic damage index for confined and unconfined concretes together with a macroscopic damage index for reinforced concrete (rc) structures under cyclic loading are proposed. in order to eliminate the problem of scale effect, an adjustable finite element computer program was generated to simulate rc structures subjected to cyclic loading. by...

OBJECTIVES/HYPOTHESIS Nonparalytic glottic incompetence (GI) encompasses a variety of laryngeal pathologies, and vocal outcome data for this group is limited. We report a subgroup analysis of validated, subjective, and perceptual voice outcome measures: voice-related quality of life (VRQOL), Glottal Function Index (GFI), and GRBAS (grade, roughness, breathiness, asthenia, and strain), after typ...

The clinical evaluation in pulmonary embolism (PE) is the first instrument used by practitioners in the management of this potentially fatal pathology. The necessity of develop- ing certain valid and especially affordable practical instruments has led to the emergence of various clinical prediction models. The purpose of this paper is to analyze the main clinical scores, as a diagnostic or a pr...

Background and aims Pulmonary embolism (PE) is associated with a significant mortality and morbidity. We aim to study clinical profile, management and outcome of PE at Shahid Gangalal National heart Centre, Kathmandu, Nepal. Methods It was a retrprospective, single centre study, conducted from January 2015 to December 2016. Haemodynamics was used for risk Simplified, PESI score, predisposing ...

OBJECTIVE The purpose of this study was to develop alternative Strain Index risk classification categories. BACKGROUND Strain Index scores are usually categorized into four Strain Index "risk categories." The "original" risk categories were developed in the meat-packing industry and may not be fully applicable to other industries. METHOD Daily Strain Index scores were estimated among 276 ma...
