UNLABELLED The aim of the present study was to describe the clinical and echocardiographic findings of ventricular noncompaction in adult patients. Fifty-three patients underwent complete clinical history, electrocardiogram, Holter and transthoracic echocardiogram. Forty patients (75%) were in class I/II of the New York Heart Association, and 13 (25%) in(More)
Transesophageal echocardiography has advantages over transthoracic technique in defining morphology of atrial structures. Even though real time three-dimensional echocardiographic imaging is a reality, the off-line reconstruction technique usually allows to obtain higher spatial resolution images. The purpose of this study was to explore the accuracy of(More)
Two of the main signal processing methods in passive SONAR are beamforming and LOFAR. In this work, an implementation in FPGA of each method was made. For beamforming, the conventional delay and sum method was selected, with free choice of time integration. A conventional FFT of 1024 points was programmed for LOFAR. Test results show the viability to(More)
In this work we describe a cognitive model to infer the more likely user's states in data-intensive contexts. Stress, mental fatigue, or even inaptitude, are selected to be inferred by the model based two sources of information: context and psycho-physiological sensors network. As long as a complex, high demanding context will predict those cognitive states(More)
