infinite dimensional garch models
مدلهای گارچ در فضاهای هیلبرت پایان نامه حاضر شامل دو بخش می باشد. در قسمت اول مدلهای اتورگرسیو تعمیم یافته مشروط به ناهمگنی واریانس در فضاهای هیلبرت را معرفی، مفاهیم ریاضی مورد نیاز در تحلیل این مدلها در دامنه زمان را مطرح کرده و آنها را مورد بررسی قرار می دهیم. بر اساس پیشرفتهایی که اخیرا در زمینه تئوری داده های تابعی و آماره های عملگری ایجاد شده است، فرآیندهایی که دارای مقادیر در فضاهای ...
15 صفحه اولInter-observer agreement between 2-dimensional CT versus 3-dimensional I-Space model in the Diagnosis of Occult Scaphoid Fractures
Background: The I-Space is a radiological imaging system in which Computed Tomography (CT)-scans can be evaluated as a three dimensional hologram. The aim of this study is to analyze the value of virtual reality (I-Space) in diagnosing acute occult scaphoid fractures. Methods: A convenient cohort of 24 patients with a CT-scan from prior studies, without a scaphoid fracture on radiograph, ye...
متن کاملO-16: Comparison of Pre-Antral Follicle Culture Development during 2 Dimensional and 3 Dimensional Culture Systems
Background: Setting up an in vitro follicle culture system that resembles in vivo ovary condition has high value in research. Additionally, expression evaluation of folliculogenesis involved genes could lead us to the designing of better culture system. Materials and Methods: ovaries of 12-day-old female NMRI mice were removed, 100-130 μm pre-antral follicles were mechanically isolated from fre...
متن کامل3–Dimensional Fabric Reconstruction from 2–Dimensional Orientation Images
3–dimensional (3d) automatic crystal orientation mapping (ACOM) allows to sample parallel 2d section raster images which represent the orientation of crystal grains. The fabric, i.e. the partition of the specimen into 3d crystal grains, can be approximated given its intersections with parallel planes provided by series of 2–dimensional raster orientation images. A method to model the 3d fabric ...
متن کاملAn Example of 2-dimensional Hyperbolic Group Which Can't Act on 2-dimensional Negatively Curved Complexes
It is a long standing open problem wether or not any word hyperbolic group admits a discrete faithful cocompact isometric action on a space of negative curvature. The goal of this note is to show that the answer is negative if one restricts to the class of groups of isometries of 2-dimensional CAT(0)-complexes. Namely, we will prove the following: Theorem 0.1 There exists a word-hyperbolic grou...
