Reconstruction of noise-corrupted surfaces may be stated as a (in general nonconvex) functional minimization problem. For functionals with quadratic data term, this paper addresses the criteria for such functionals to be convex, and the variational approach for minimization. I present two automatic and general methods of approximation with convex functionals based on Gaussian convolution. They ...

the main purpose of this research was to study different aspects of self-employment among the agricultural female students in university of zanjan. the statistical population of the study contained of senior female students in agriculture faculty of zanjan university in 2014-2015 academic year (n= 135).according to cochran's formula, 63 student were selected using a stratified random sampl...

PROBLEM It has been established that graduated licensing systems lead to crash reductions among beginning drivers. What is the contribution of the various components of graduated licensing to these reductions, and how can their effectiveness be increased? METHOD Literature review and synthesis. RESULTS Extended learner periods, nighttime restrictions, and passenger restrictions have contrib...

abstract in iran, most english teachers’ method of teaching writing is merely to have students do some writing exercises or simply to give them writing tests without any instruction, but writing is not an easy task for students, and teachers should be able to do more to facilitate their students’ writing. one of the ways to aid writing is dynamic assessment via graduated prompt. the graduated p...

background and purpose: the application of diagnostic, therapeutic, and prognostic evidence in day-to-day management of patients has been in constant focus during the last two decades. this study is an attempt to investigate attitude and knowledge of post-graduated medical students and lecturers towards evidence-based medicine (ebm) and assess their preferences to clinical practice guidelines. ...

This is the latest in a series of reviews of research on graduated driver licensing (GDL) published in the Journal of Safety Research, covering the period January 1, 2010-June 1, 2012 and work in progress. The intent is to keep researchers and policy makers current regarding the existing state of knowledge about GDL, and to identify information gaps and areas where clarification of research fin...

Graduated compression stockings are frequently used in the prevention of deep venous thrombosis and the treatment of venous insufficiency. Two patients are discussed who sustained ischaemic complications after application of graduated compression stockings. Review of the literature demonstrates that low cutaneous pressures significantly decrease local blood flow and that the amount of pressure ...

Many high dimensional data mining problems can be formulated as minimizing an empirical loss function with a penalty proportional to the number of variables required to describe a model. We propose a graduated non-convexification method to facilitate tracking of a global minimizer of this problem. We prove that under some conditions the proposed regularization problem using the continuous piece...
