We present a novel scheme for the transmission of H.264/AVC video streams over packet loss networks. The proposed scheme exploits the error resilient features of H.264/AVC codec and employs Reed-Solomon codes to protect effectively the streams. A novel technique for adaptive classification of macroblocks into three slice groups using Flexible Macroblock Ordering is also proposed. The optimal cl...

In this paper, we proposed an intra 16×16 line-by-line (LbL) prediction. First, we find suitable quantization parameters (QP) for the high resolution videos without the significant subjective quality degradation. Then, we show that closer reference pixels give better prediction through the experiment. Using this observation, we propose an improved intra prediction method. In the proposed method...

Introdução. O Acidente Vascular Cerebral (AVC) é uma condição que pode resultar em prejuízos neurológicos e levar à incapacidade funcional. A disfagia alteração na biomecânica da deglutição frequentemente estar presente indivíduos acometidos por AVC. trombólise endovenosa o tratamento mais indicado eficaz quando administrado no momento certo, restabelecendo fluxo sanguíneo área afetada.

PURPOSE We evaluated various preoperative anterior segment parameters measured with a Pentacam rotating Scheimpflug camera and compared them with those of conventional methods. We also evaluated the effect of different parameters on corneal endothelial cells after cataract surgery. METHODS Pentacam examination was performed in 88 eyes from 88 patients to evaluate central anterior chamber dept...

English. Human Resources are one of the most important assets in modern organizations. Their capability of facing employees’ needs is critical in order to have an effective and efficient company, where people are the center of all business processes. This work is focused on developing new techniques that, leveraging a data driven approach, can help Human Resources to find a more precise employe...

L’obesità è una condizione che interessa più del 30% della popolazione degli USA contro l’11% di quella italiana. Essa, oltre a comportare un maggior rischio di sviluppo di patologie croniche, determina un aumento della spesa sanitaria: è sempre più frequente, in sala operatoria e in terapia intensiva, la gestione di un paziente con un BMI > 30 Kg/m che richieda una strategia diversa rispetto a...

The chemical effects of acoustic cavitation are obtained in sono-reactors built-up from a vessel and an ultrasonic source. In this paper, simulations of an existing sono-reactor are carried out, using a linear acoustics model, accounting for the vibrations of the solid walls. The available frequency range of the generator (19-21 kHz) is systematically scanned. Global quantities are plotted as a...

This document describes the participation of the INGEOTEC team in SENTIPOLC 2016 contest. In this participation two approaches are presented, B4MSA and B4MSA + EvoDAG, tested in Task 1: Subjectivity classification and Task 2: Polarity classification. In case of polarity classification, one constrained and unconstrained runs were conducted. In subjectivity classification only a constrained run w...
