Situation Type, Context Coercion and the Meanings of the Chinese Aspect Marker Le
… test, and an on-line experiment which used the moving window paradigm to investigate the processing of le in situation-concordant sentences (aspectually transparent, with no situation shift) and situation-coerced sentences (through context coercion). The results of the three experiments support …

P- and S- wave tomography of the crust and uppermost mantle in China and surrounding areas
… this research are: 1) introducing the adaptive moving window method to obtain 2338 1D P and S models in China; 2) introducing a tomographic method to perform the 3D body wave travel-time tomography with the Moho discontinuity included. Both horizontal and vertical resolutions are highly …

Online Processing of Wh-Dependencies in English by Native Speakers of Spanish
… experiments run in a word-by-word non-cumulative moving window paradigm (Just et al., 1982). Experiment 1 tested if second language (L2) learners process wh-dependencies incrementally by looking at wh-extraction from positions licensed by the grammar. Experiment 2 focused on testing if learners …

Fine-grained reputation-based routing in wireless ad hoc networks
… actions in either case. We employ the moving-window mechanism which enables us to assign more weight to more recent observations and adjust responsiveness of our reputation system to changes in nodes’ behavior. We show that our fine-grained reputation system is able to improve both …

Forecasting the Prices of Cryptocurrencies using a Novel Parameter Optimization of VARIMA Models
… Models are trained on this historical data using moving window subsets, with window lengths of 100, 200, and 300 days and forecasting 1 day into the future. Validation of this prediction against the actually price from that day are done with following metrics: Directional Forecasting (DF), Mean …

GLR Control Charts for Monitoring a Proportion
… binomial GLR statistic is constructed based on a moving window of past sample statistics that follow a binomial distribution. Steady state performance is evaluated for the binomial GLR chart and the other widely used binomial charts. We find that in terms of the overall performance, the binomial …

The use of fractal dimension for texture-based enhancement of aeromagnetic data.
… FDs when applied to entire profiles or in a moving window along the profile. Generally, the accuracy of the estimated FD improves when window size is increased. Similarly, the standard deviation of estimated FD decreases as window size increases. This result implied that the use of moving …

Individual differences in syntactic processing during reading: a psycholinguist’s “two disciplines” problem
… 133 young adults read sentences via a self-paced moving window paradigm and then completed a battery of 16 tasks to assess their abilities in the following areas: language experience, phonological ability, working memory, inhibitory control, and perceptual speed. Three syntactic phenomena were …

Morphological variability in long-distance subject-verb agreement: A study of native and nonnative processing
… completed an online reading task using a moving window self-paced reading paradigm. In order to explore whether increases in structural distance between agreeing elements leads to decreases in sensitivity to agreement violations (Clahsen & Felser, 2006; Gabriele et al., in press), …

Measurement of physiological variables by dynamic Gd-DTPA enhanced MRI
… on the modification of existing approaches and moving-window algorithms for the measurement of black-box quantifiers of DEMRI. The measurements were performed in two angiogenesis dependent diseases: breast cancer and rheumatoid arthritis (RA). In a study involving QDEMRI analysis of 59 primary …

A comparative analysis of terrestrial laser scanning (TLS) and structure from motion (SfM) photogrammetry for measuring fluvial sediments
… of TLS point-clouds. For each data set, a 0.19 m moving window (consistent with the largest sediment clast b axis) was applied to the resulting point-clouds. Two times standard deviation of elevation was calculated in order to provide a surrogate measure of grain protrusion, from which sediment …

Self-efficacy and allocation of effort during reading among older and younger adults
… Questionnaire. Using the on-line word-by-word moving window method, participants read 24 two-sentence passages for immediate recall after reading either comparatively easier or more difficult texts. Younger adults reported higher Memory Self-Efficacy (MSE) and higher Reading Self-Efficacy …

Detecting the socioeconomic conditions of urban neighborhoods through wavelet analysis of remotely sensed imagery
… discrimination of urban neighborhoods; and 4) window size had great influences on the discrimination of urban neighborhoods. In addition, two technical problems related to the application of textural approach, including the edge effect and image segmentation problem, were examined. The results …

Debiasing Cyber Incidents – Correcting for Reporting Delays and Under-reporting
… delay distribution over the rolling two-year moving window, the bimodal aspect required an optimization algorithm to compute the parameters. The modeled parametric distribution is further extended to infinite domain to obtain the complete overview of the incidents occurred but not yet …

Weibull mixture model for grouped data and pattern identification in spatial and spatial-temporal data.
… are pooled to construct outlier bounds using a moving window technique. The observations whose residuals fall outside of the outlier bounds are flagged as outliers. Artificial outliers are generated and added to the ground deformation data to study the accuracy and stability of the proposed …

Alternative risk management: correlation and complexity
… equity returns (medium frequency data), using a moving window approach. This novel characterisation, dependent on both large and small eigenvalue behaviour, is shown to be consistent across different time scales. Further, frequency dependent correlations were examined for medium and …

Data Reduction in Smart Grid
… (DR-LADA). Also, the proposed approach uses a moving window technique to mitigate the dynamic measurement of the grid. Similarly, we consider their applications in load pro ling relevant to demand side management using k-means cluster algorithm. Some non-linear dimensionality reduction …

Evaluation of linear and nonlinear vibration methods to characterize induced microstructural damage in portland cement-based materials
… fast dynamic response was measured using a moving window regime on a single transient time domain response. The nonlinear slow dynamic response was measured using a simple repeated impulse vibration procedure. Linear resonant frequency data were very consistent and reduced with increasing …
