Predicting Mortality of ICU Patients Using Statistics of Physiological Variables and Support Vector Machines

We began using the same variables as SAPS-1 score, adding the rest of variables one by one as recommended by physicians, to observe whether the SVM classification improves. These variables include: Age, HR, SysABP, NISysABP, Temp, RespRate, MechVent, Urine, BUN, HCT, WBC, Glucose, K,

3D modeling and parameterization of the left ventricle in echocardiographic images using deformable superquadrics

This paper proposes a new method for the quantitative analysis of the mobility of the left ventricle LV, based on a 3D dynamic model. One superquadric is used as the 3D global model. For data acquisition, an electromechanical device that allows acquiring the volume of images using ach
