Background: Autism spectrum disorder (ASD) is characterized by difficulty in the areas of social functioning, communication , and the presence of stereotypic and repetitive behaviors. Video modeling has been found to be an effective procedure for teaching a variety of skills to persons with autism. The purpose of the current study was to investigate the efficacy of video modeling procedure on...
there are many different ways to subdivide the spectrum of a bounded linear operator; some of them aremotivated by applications to physics (in particular, quantum mechanics). in this study, the relationship betweenthe subdivisions of spectrum which are not required to be disjoint and goldberg's classification are given.moreover, these subdivisions for some summability methods are studied.
Optical spectrum analysis and polarization analysis are not generally related by conventional wisdom. In this paper, we show that the spectrum of a light beam can be obtained using a polarimeter, with a resolution and a speed that cannot be achieved with traditional spectrum analysis methods. We experimentally demonstrate a novel polarimeter-based optical spectrum analyzer (P-OSA) and show that...
We describe what we believe to be novel methods for waveform synthesis and detection relying on longitudinal spectral decomposition of subpicosecond optical pulses. Optical processing is performed in both all-fiber and mixed fiber-free-space systems. Demonstrated applications include ultrafast optical waveform synthesis, microwave spectrum analysis, and high-speed electrical arbitrary waveform ...

OBJECTIVES To investigate the long-term development of the post-cure degree of conversion (DC) for two flowable bulk-fill composites. MATERIALS AND METHODS Tetric EvoFlow Bulk Fill (TEFBF) and SDR were chosen due to their distinct compositional modifications that enable the decrease of translucency during polymerization and lower polymerization rate, respectively. DC was assessed using FT-Ram...
Highly-ordered, parallel gradient P3HT stripes are fabricated through a facile deposition method based on controlled evaporative self-assembly (CESA). Confocal polarized Raman spectroscopy is employed to determine the orientation of P3HT chains in individual stripes and spacing. This is the first report on orientation at the molecular level, beyond sole morphology, in the patterns assembled by ...
High vocal effort has characteristic acoustic effects on speech. This study focuses on the utilization of this information by human listeners and a machine-based detection system in the task of detecting shouted speech in the presence of noise. Both female and male speakers read Finnish sentences using normal and shouted voice in controlled conditions, with the sound pressure level recorded. Th...
In this paper, we develop a new extension of the singular spectrum analysis (SSA) called functional SSA to analyze time series. The methodology is constructed by integrating ideas from data and univariate SSA. Specifically, introduce trajectory operator in world, which equivalent matrix regular SSA, one needs obtain value decomposition (SVD) decompose given Since there no procedure extract SVD ...
