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 ...

A Continuous Time GARCH Process Driven by a Lévy Process: Stationarity and Second Order Behaviour [PDF]
, 2005 We use a discrete time analysis, giving necessary and sufficient conditions for the almost sure convergence of ARCH(1) and GARCH(1,1) discrete time models, tosuggest an extension of the (G)ARCH concept to continuous time processes.

Particle modelling of an elastic arch
Applied Mathematical Modelling, 1985 A new particle-type of modelling has been developed for the simulation of phenomena related to the bending of an elastic arch. Application is made to the simulation of snap-through inversion and to the simulation of unstable equilibrium modes. Computer examples are described and discussed.

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

A Binomial Integer-Valued ARCH Model [PDF]
The International Journal of Biostatistics, 2015 Abstract We present an integer-valued ARCH model which can be used for modeling time series of counts with under-, equi-, or overdispersion. The introduced model has a conditional binomial distribution, and it is shown to be strictly stationary and ergodic.

Stationarity and geometric ergodicity of a class of nonlinear ARCH models [PDF]
, 2006 A class of nonlinear ARCH processes is introduced and studied. The existence of a strictly stationary and $\beta$-mixing solution is established under a mild assumption on the density of the underlying independent process.

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 ...

Accuracy of Digital Models in Orthodontic Diagnosis
Turkish Journal of Orthodontics, 2008 The overall objective of this study is to compare the measurements of plaster models and digital models on teeth with dental abnormalities. Pretreatment orthodontic models of 30 patients were selected from the archive of our university clinic.

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 ...
