tight frame approximation for multi-frames and super-frames
در این پایان نامه یک مولد برای چند قاب یا ابر قاب تولید شده تحت عمل نمایش یکانی تصویر برای گروه های شمارش پذیر گسسته بررسی خواهد شد. مثال هایی از این قاب ها چند قاب های گابور، ابرقاب های گابور و قاب هایی برای زیرفضاهای انتقال پایاست. نشان می دهیم که مولد چند قاب تنک نرمال شده (ابرقاب) یکتا وجود دارد به طوری که مینیمم فاصله را از ان دارد. همچنین مسایل مشابه برای قاب های دوگان مطرح شده و برخی ...

OPEN ACCESS ISSN: 2473-067X Letter to the Editor We present a case of an unstable proximal interphalangeal fracture of the fifth finger. We want to review the treatment of this entity, by using a dynamic exter...
متن کاملParametric analyses of pin-bone stresses in external fracture fixation devices.
Problems occurring in the use of external fixators for bone fractures include pin-bone interface necrosis, infection, and loosening. These may be initiated and enhanced by pin-bone interface stress levels. Based on stress data from finite element method (FEM) models, an analytical "closed-form" model of the local pin-bone configuration in long-bone fracture fixation is developed. This model is ...
متن کاملExternal fixation for phalangeal and metacarpal fractures.
From 1987 to 1993 we treated 33 patients with 29 phalangeal and seven metacarpal fractures by external fixation using a mini-Hoffmann device. There were 27 open and 25 comminuted fractures. In 12 patients one or more tendons was involved. The mean follow-up was 4.4 years. Complications occurred in ten fractures; two required repositioning of the fixator. All the fractures healed. The functional...
متن کاملThe Ilizarov external fixation frame in compression arthrodesis of large, weight bearing joints.
Solid bony fusion of large joints affected with active chronic infections, is still the most effective surgical solution to establish a useful function of the affected limb. Even with extensive peri-articular bone loss and severe deformities, arthrodesis in a functional position can provide effective stability. The reported fusion rates in such patients are not encouraging however, and secondar...
