Three-dimensional of lingual arch form and creation of templates in Iraqi normal occlusion
Journal of Orthodontic Science, 2023 OBJECTIVES: To evaluate the lingual dental arch form types in class I canine and molar relationship based on scanning dental cast models using three-dimensional laser scan and to give a new lingual arch form pattern created on this classification to be ...

Evaluation of Combined ARMA-ARCH and BL-ARCH models in Modeling Lake Urmia water level [PDF]
علوم و مهندسی آبیاری, 2017 Many nonlinear models have been developed based on the mean errors modeling. However, the non-linear models with Autoregressive conditional heteoscedasticity are based on variance modeling. These models are combined with linear models, partly to increase

Statistical inference for time-varying ARCH processes [PDF]
, 2006 In this paper the class of ARCH$(\infty)$ models is generalized to the nonstationary class of ARCH$(\infty)$ models with time-varying coefficients. For fixed time points, a stationary approximation is given leading to the notation ``locally stationary ...

A Survey of Recent Theoretical Results for Time Series Models with GARCH Errors, [PDF]
, 2001 This paper provides a review of some recent theoretical results for time series models with GARCH errors, and is directed towards practitioners. Starting with the simple ARCH model and proceeding to the GARCH model, some results for stationary and ...

Activity autocorrelation in financial markets. A comparative study between several models
, 2003 We study the activity, i.e., the number of transactions per unit time, of financial markets. Using the diffusion entropy technique we show that the autocorrelation of the activity is caused by the presence of peaks whose time distances are distributed ...

Comparative Study of MDCT with Plaster Cast Model of Dentoalveolar Arch Morphology [PDF]
International Journal of Anatomy Radiology and Surgery, 2017 Introduction: Dentoalveolar arch morphology and its measurements are of importance in various disciplines of dental science. It is usually studied by impression plaster cast models with mechanical calipers or scanned and digitized dental models ...
