An examination of the Effectiveness of a Cognitive Group Intervention for People with Acquired Brain Injury
… Making Test; Sustained Attention Response Task (SART); and Digit-Span Task) and questionnaires (Community Integration Questionnaire; Satisfaction With Life Scale; Hospital Anxiety and Depression Scale; Cognitive Group Self-Evaluation; and Knowledge of Brain Injury Questionnaire) at three …

The Relationship between Bilingualism, Cognitive Control, and Mind Wandering
… on Operation Span, Numerical Stroop, SART, Color- Shape, and Letter Memory tasks, which are measures of working memory, proactive inhibition, reactive inhibition, shifting, and updating, respectively. We further hypothesized that if bilinguals outperformed monolinguals on these tasks, …

Three-Dimensional Morphology of Polymer Nanocomposites Characterized by Transmission Electron Tomography
… results of MgO (cube-shape) generated by FBP, SART and SIRT tomographic algorithms under various reconstruction conditions, i.e. tilting range and increment. Examining the experimental data with known morphology permits quantitative determination of the accuracy of the reconstruction results by …

A survey of algebraic algorithms in computerized tomography
… algebraic reconstruction algorithms (ART, SART, Cimmino's Method, CAV, DROP) for extensive testing and the results are reported in this thesis. The quantitative numerical results obtained in this study, con rm the qualitative suggestion that algebraic techniques are not yet adequate for …

Image reconstruction and imaging configuration optimization with a novel nanotechnology enabled breast tomosynthesis multi-beam X-ray system
… simultaneous algebraic reconstruction technique (SART), were implemented to fit our system design. An accelerated MLEM algorithm was proposed, which significantly reduced the running time but had the same image quality. Furthermore, two statistical variants of BP reconstruction were validated for …

The Relationship Between Emotion-Related Thoughts and Emotional Recovery from Stress
… and negative affective recovery following the SART. These findings suggest that emotion-related thoughts are an important factor in recovery from a stressful stimulus.

The effects of exercise intensity and cognitive load on acute changes in attention and vigilance in healthy young adults
… a 3-min sustained attention to response test (SART) was performed before and immediately, 15, 30, 45 and 60-min after each session. Although exercise intensity was significantly different between exercise sessions (p<0.01), no significant differences (p=0.372) were observed for changes in …

Design and prototyping of a test facility to investigate the transport properties of dilute phase gas-particle flows applicable to coal-fired power plants
Understanding the properties of dilute phase gas-particle transport and the applicability of the different empirical correlations found in literature for these properties are crucial in the study of Pulverized Fuel conveying applicable to South African coal-fired power plants. Having access to a …

The Influence of Emotion on the Risk Perception and Situation Awareness of Clinicians
… under induced anger. Sub-constructs within 3-D SART correlated with emotional responses and anthropomorphic computer character intervention. Two additional items, supply of attention and complexity of the situation, were also found to be influenced by anthropomorphic computer character …

Modeling and Development of Iterative Reconstruction Algorithms in Emerging X-ray Imaging Technologies
… solved by use of the ordered subset concept (OS-SART). In addition, we also present efficient numerical implementations of the proposed algorithms that exploit the massive data parallelism of multiple graphics processing units (GPUs). Finally, we employed our developed accelerated version of …

Imaging Techniques for Proton Range Determination in Proton Therapy
… technique with total variation regularization (SART-TV). When the proposed reconstruction approach was applied, the percentage deviations from reference SPR were within ±1% in all selected ROIs. The mean absolute error of the reconstructed SPR was 0.33%, 0.19%, and 0.27% for the cylindrical …
