Allen, G.M. (author), Wright, Katherine Landau (author), Fails, Jerry Alan (author), Kennington, Casey (author), Pera, M.S. (author)We introduce a re-ranking model that augments the functionality of standard search engines to aid classroom search activities for children (ages 6–11). This model extends the known listwise learning-to-rank framework by balancing risk and reward. Doing so enables the model to prioritize Web resources of high educational alignment,...conference paper 2023

Wright, K.E. (author), Stempien, John (author), Jiang, Wen (author), van Rooyen, Isabella J. (author)Two tristructural isotropic (TRISO)-coated nuclear fuel particles were examined by electron probe microanalysis (EPMA) as part of the Advanced Gas Reactor program. The compacts’ average irradiation temperatures ranged from approximately 1260 to 1290 °C. One particle was examined in the as-irradiated condition, while the other was subject to...journal article 2022

Wright, K.E. (author), Stempien, John D. (author), van Rooyen, Isabella J. (author)Two irradiated AGR-2 TRISO particles were chosen to demonstrate a recently developed mass balance technique in which EPMA-generated concentration data were used to determine fission product mass on a layer-by-layer basis in TRISO particles. EPMA-calculated fission product masses for most fission products in the two particles were within ± 20%...journal article 2022

(author), Alon, Elad (author)We present a ring-oscillator-based sub-sampling phase-locked loop (PLL) using a generator-based design flow. A hybrid loop with a delta-sigma ($\Delta \Sigma$) modulator is applied to reduce the loop filter (LF) area and the control ripple. The generator automatically produces the ring oscillator and PLL to meet the provided specifications. The...conference paper 2022

Pearson, S.G. (author), van Prooijen, Bram (author), Poleykett, Jack (author), Wright, Matthew (author), Black, Kevin (author), Wang, Zhengbing (author)Sediment tracer studies use uniquely identifiable particles to track the pathways and fate of individual sand or silt grains in marine environments. These techniques are best applied to assess connectivity between potential sediment sources and sinks, such as between a sand nourishment and an ecologically sensitive area. Significant challenges...journal article 2021

Cristiano, E. (author), ten Veldhuis, Marie-claire (author), Wright, Daniel B. (author), Smith, James A. (author), van de Giesen, N.C. (author)Interactions between spatial and temporal variability of rainfall and catchment characteristics strongly influence hydrological response. In urban areas, where runoff generation is fast due to high imperviousness degree, it is especially relevant to capture the high spatiotemporal rainfall variability. Significant progress has been made in...journal article 2019

Bekaert, D.P.S. (author), Hooper, A. (author), Wright, T.J. (author)In Guerrero, Mexico, slow-slip events have been observed in a seismic gap, where no earthquakes have occurred since 1911. A rupture of the entire gap today could result in a Mw 8.2–8.4 earthquake. However, it remains unclear how slow-slip events change the stress field in the Guerrero seismic region and what their implications are for...journal article 2015
