Note on curve and surface energies
Energies of curves and surfaces together with their discrete variants play a prominent role as fairness functionals in geometric modeling and computer aided geometric design. This paper deals with a particular discrete surface energy which is expressible in terms of curve energies, and which occurs naturally in the problem of smoothing digital elevation data with tolerance zone constraints. We ...
متن کاملA Note on Y-energies of Knots
We study a 1-form which can be given by a vector in a conformally invariant way. We then study conformally invariant functionals associated to a “Y-diagram” on the space of knots which are made from the 1-form.
متن کاملthe effects of cognitive strategies- note making and underlining- on iranian efl learners’ reading comprehension
هدف از انجام این مطالعه ، بررسی اثرات استفاده از استراتژی های شناختی یعنی "نت برداری" و "زیر خط کردن" بر روی عملکرد درک مطلب زبان آموزان ایرانی می باشد. به این منظور، 60 زبان آموز دختر سال چهارم دبیرستان از طریق آزمون پیشرفت زبان انگلیسی (نلسون)، از یک جامعه آماری بزرگتر انتخاب شدند. سپس به صورت تصادفی به سه گروه که هر گروه شامل ?0 دانش آموز همسان بود، تقسیم شدند: دو گروه آزمایش(گروه "نت برداری...
15 صفحه اولOn Some Variational Problems Involving Volume and Surface Energies
We show how some problems coming from different fields of applied sciences such as physics, engineering, biology, admit a common variational formulation characterized by the competition of two energetic terms. We discuss related problems and techniques studied by the authors and collaborators in the recent past as well open problems and further possible research directions in these topics.
متن کامل36 Curve and Surface Reconstruction
The problem of reconstructing a shape from its sample appears in many scientific and engineering applications. Because of the variety in shapes and applications, many algorithms have been proposed over the last three decades, some of which exploit application-specific information and some of which are more general. We focus on techniques that apply to the general setting and have geometric and ...
