Authors: Arundel, S.T.; Advisor: -; Participants: - (2016) - As the new National 3D Elevation Program (3DEP) prepares to provide high-resolution lidar coverage for continental United States, Hawaii, and the territories, it is important to consider that terrain information captured in elevation data are pixel-based instead of feature-based. Referencing 3DEP data for semantic access and inferencing requires the transcription of pixels into accessible features. Indeed, accessing and inferencing terrain features renders them more operational for long-term national mapping. Much progress has been made in transcribing pixels into terrain features using Geographic Object-Based Image Analysis (GEOBIA), as compared to traditional, pixel-based image anal...

Authors: Yousif, El-Sayed I.; Advisor: -; Participants: Yaseen, Attia A.; Abdel-Fatah, Abdel-Fatah A.; Shouk, Abdel-Hafeez A.; Gadlla, Mohamed G.; Mohammad, Ayman A. (2020) - Loaf volume significantly (p ≤ 0.05) decreased, while loaf weight increased by increasing the level of all tested materials as compared to control bread. Hardness and chewiness of bread samples increased, while springiness and cohesiveness decreased by increasing the level of replacement of all nano-materials. The control bread had the lowest value of alkaline water retention capacity (AWRC) being 326, 292, 265, and 237%, respectively for 3, 24, 48, and 72 h of storage time at room temperature. At all levels of replacing, noticeable increase of AWRC was detected as well as retarding staling rate of bread during storage.

Authors: Urbina, C.A.F.; Advisor: -; Participants: van den Berg, F.; van Dam, J.C.; Tang, D.W.S.; Tang, D.W.S. (2020) - The outputs analyzed were the concentration in drainage water, the average concentration in groundwater between 1 and 2 m, and the concentration in the soil system at 100‐cm depth. Influential parameters found through the Morris method were analyzed using the Sobol–Jansen method. The results for bentazon indicate that the degradation half‐life (DT50), the bottom depth of the internal catchment (zic), and the proportion of the internal catchment at the soil surface (pic_0) are critical parameters in all the outputs analyzed. For imidacloprid and compound I, the most relevant parameters for drainage output are the Freundlich sorption exponent (Fexp) and zic; for groundwater, the relevan...

Authors: Doan, Tat Khoa; Advisor: -; Participants: Le, Xuan Hung; Nguyen, Trung Thanh; Pham, Quoc Hoang (2019) - This paper addressed a multi-response optimization to enhance the power factor (PF) and decrease the energy consumption (EC) for the dry machining AISI H13 steel. The cutting speed (V), depth of cut (a), feed rate (f), and nose radius (r) were the processing inputs. The relationships between inputs and outputs were established using the response surface models (RSM). The desirability approach (DA) was used to observe the optimal values. The results showed that the technical outputs are primarily influenced by the f and V. The reduction of EC is approximately 33.84%, while the PF improves around 33.12%, respectively, as compared to the initial parameter setting.

Authors: Claes, N.; Advisor: -; Participants: Paige, G.B.; Grana, D.; Parsekian, A.D. (2020) - We assessed four model structures each with three soil types of homogeneous hydrologic properties, two of which were evaluated with and without an anisotropy factor. Wetting front arrival times, derived from time‐lapse electrical resistivity measurements during flood irrigation field experiments, were used to evaluate the different representations of soil profile structures. These data indicated both vertical and lateral preferential flow in the subsurface during flood irrigation. Inclusion of anisotropy in the saturated hydraulic conductivity field improved the ability to model subsurface hydrologic behavior when flow processes shifted from uniform to heterogeneous flow, as occurs wi...

Authors: Cai, C.; Advisor: -; Participants: Vanderborght, J.; Couvreur, V.; Mboh, C.M.; Vereecken, H. (2018) - These models were implemented in HYDRUS‐1D, and soil hydraulic parameters were optimized by inverse modeling using soil water content and potential measurements and observations of root distributions of winter wheat (Triticum aestivum L.) in horizontally installed rhizotubes. Soil moisture was equally well predicted by the three models, and the soil hydraulic parameters optimized by the models with compensation were comparable. The obtained RWU parameters of the Feddes–Jarvis model were consistent with data reported in the literature, although the pressure heads h3l and h3h for lower and higher transpirations rates, respectively, could not be uniquely identified. Response surfaces of ...

Authors: Boerboom, Luc; Malek, Žiga; Advisor: -; Participants: - (2015) - Changes to land use such as the removal of natural vegetation and expansion of urban areas can result in degradation of the landscape and an increase in hydro-meteorological risk. This has led to higher interest by decision-makers and scientists in the future consequences of these drivers. Scenario development can be a useful tool for addressing the high uncertainty regarding modeling future land use changes. Scenarios are not exact forecasts, but images of plausible futures. When studying future land dynamics, emphasis should be given to areas experiencing high rates of socioeconomic change. We have focused on the eastern Italian Alps, which face increasing pressure from tourism deve...

Authors: Layer, M.; Advisor: -; Participants: Bock, K.; Ranzinger, F.; Horn, H.; Morgenroth, E.; Derlon, N. (2020) - Hence, large fractions of influent XB likely re-suspended during aerobic fully-mixed conditions, where XB then preferentially and rapidly attached to the flocs. During fully-mixed conditions, increasing floc fractions, longer mixing times and larger XB concentrations increased XB retention. Elevated XB retention was observed after short mixing times < 60 min when flocs were present, and the contribution of flocs towards XB retention was even more pronounced for short mixing times < 5 min. Overall, our results suggest that flocs occupy an environmental niche that results from the availability of XB during aerobic fully-mixed conditions of AGS SBR. Therefore, a complete wash-out of floc...

Authors: Jiang, Y.; Advisor: -; Participants: Wang, T.; Wu, Y.; Hu, R.; Huang, K.; Shao, X. (2018) - Results showed that the model with the predictors at a 15‐km resolution achieved the highest predictive accuracy (AUC=0.946; TSS=0.880), although there was no statistically significant difference between the four models (p > 0.05). The most significant environmental variables included aridity, annual precipitation, precipitation of wettest month, precipitation of wettest quarter, and precipitation of warmest quarter, annual mean NDVI, and minimum NDVI. The predicted suitable areas for epiphyllous liverworts were mainly located in the south of Yangtze River and seldom exceed 35°N, which were consistent with the museum and herbarium records, as well as the historical records in scientif...
