OBJECTIVE Evaluation of the functional results of the Delta 3 inverted shoulder prosthesis and determination of a radio-anatomical index predictive of best functional outcome. PATIENTS AND METHODS Retrospective analysis of 19 patients (21 shoulders). Clinical (pain, satisfaction, amplitudes, Constant index) and radiological (acromio-epiphyseal distance)(More)
The precise segmentation of optic disc is a major task in developing automated systems for diagnosis of retinal diseases using colored fundus images. The noise, illumination effects, blood vessels and lesions like exudates make it really challenging to build an efficient OD segmentation method using fundus images. This paper presents a novel method for(More)
A study of 79 twin pregnancies was conducted between 1973 and 1976 with particular reference to the use of ultrasound and hormone analysis. There were 17 perinatal deaths, a perinatal mortality rate of 107 per 1000 deliveries. The contributing factors were antepartum anoxia (40%), prematurity (30%), congenital abnormalities (18%), and obstetric trauma(More)
This paper deals with five existing nonlinear estimators (filters), which include Extended Kalman Filter (EKF), Extended H-infinity Filter (EHF), State Dependent Filter (SDF), State Dependent H-Infinity Filter (SDHF) and Unscented Kalman Filter (UKF) that are formulated and implemented to estimate unmeasured states of a typical biological wastewater system.(More)
