Finite elements allow smoothness to be enforced on the measurement of the image-dependent term in active contours. This improves the stability of the solution, with less computational cost than is incurred by increasing the number of elements. Performance is best when the size of the element matches the scale of the image detail sought. This property of Finite elements can be used deliberately ...

OBJECTIVE To compare the parasitological and clinical efficacy of four weeks versus two weeks of treatment with aminosidine (paromomycin) ointment in patients with cutaneous leishmaniasis caused by Leishmania major in the Islamic Republic of Iran. METHODS Double-blind, randomized trial of four weeks of aminosidine ointment (n = 108) vs two weeks of aminosidine ointment and two weeks of placeb...

This research shows that active learning is not universally effective and, in fact, may inhibit learning for certain types of students. The results of this study show that as increased levels of active learning are utilized, student test scores decrease for those with a high grade point average. In contrast, test scores increase as active learning is introduced for students in the lower level g...

AbsfrucfThe use of energy-minimizing curves, known as “snakes” to extract features of interest in images has been introduced by Kass, Witkin and Tenopoulos [W]. A balloon model was introduced in [12] as a way to generalize and solve some of the problems encountered with the original method. A 3-D generalization of the balloon model as a 3-D deformable surface, which evolves in 3-D images, is pr...

Twenty two patients with multiple sclerosis, complaining of frequency of day time micturition, completed a double blind crossover trial of desmopressin (DDAVP nasal spray) versus placebo. There was a significant decrease in micturition frequency in the 6 hour post-treatment period from 3.1 voids after placebo to 2.4 voids and a significant reduction in urinary volume after desmopressin. Eighty ...

This paper presents an analysis of the involvement of the penalty parameter in exact penalty function methods that yields modiications to the standard outer loop which decreases the penalty parameter (typically dividing it by a constant). The procedure presented is based on the simple idea of making explicit the dependence of the penalty function upon the penalty parameter and is illustrated on...

A new method for the solution of minimization problems with simple bounds is presented. Global convergence of a general scheme requiring the solution of a single linear system at each iteration is proved and a superlinear convergence rate is established without requiring the strict complementarity assumption. The theory presented covers Newton and Quasi-Newton methods, allows rapid changes in t...
