After an initial functional analysis of a participant's aggression showed unclear outcomes, we conducted preference and reinforcer assessments to identify preferred forms of attention that may maintain problem behavior. Next, we conducted an extended functional analysis that included a modified attention condition. Results showed that the participant's aggression was maintained by access to pre...

An analogue functional analysis identified attention as a function for a 5-year-old boy's bruxism (teeth grinding). Functional communication training resulted in a reduction of bruxism and an increase in alternative mands for attention. Results were maintained 3 weeks following the intervention.
Functional data analysis is a growing research field and numerous works present a generalization of the classical statistical methods to function classification or regression. In this paper, we focus on the problem of using Support Vector Machines (SVMs) for curve discrimination. We recall that important theoretical results for SVMs apply in functional space and propose simple functional kernel...
In this work we propose a modern statistical approach to the analysis and modeling of dynamics in online auctions. Online auction data usually arrive in the form of a set of bids recorded over the duration of an auction. We propose the use of a modern statistical approach called functional data analysis that preserves the entire temporal dimension in place of currently used methods that aggrega...
موضوع: پوکی استخوان به عنوان شایعترین بیماری متابولیک استخوان،یکی از عوامل مهم ایجاد کایفوز پشتی ستون فقرات و افزایش احتمال خطر سقوط است. استفاده از ارتزها یکی از روش های درمانی است که در خصوص ارزشمندی آنها برای بهبود تعادل اتفاق نظر وجود ندارد. هدف از انجام این مطالعه بررسی تاثیر ارتز وزنه دار کایفوز بر میزان خطر سقوط در زنان مبتلا به پوکی استخوان اولیه بود. روش بررسی: طی یک مطالعه کارآزمائ...
This paper shows the application of a functional version of principal component analysis to build a parametrization of vocal tract area functions for vowel production. Sets of measured area values for ten vowels are expressed as smooth functional data and next decomposed into a mean area function and a basis of orthogonal eigenfunctions. Interpretations of the first four eigenfunctions are prov...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
An important aspect of the requirements engineering process is the specification of traceable, unambiguous and operationalizable non-functional requirements. This remains a non-trivial task due to the lack of well-documented, systematic procedures that facilitate a structured analysis of the qualitative data that is typically the input to this activity. This research investigates the developmen...
