Burnout: How To Spot It And Take Action, Geri Boyer Mar 2024

Burnout: How To Spot It And Take Action, Geri Boyer

Purdue Road School

Every project’s goal is to meet or exceed scope, schedule, and budget. However, despite excellent project management, employee burnout can hinder this objective. Burnout causes employees to lose focus, make mistakes, and take longer to finish tasks. Burnout is also terrible for your short and long-term well-being. This presentation will identify early indicators of burnout and offer a recovery plan that can help employees recover from burnout and prevent it from occurring again.

Exploration And Implementation Of Autonomous Truck Mounted Attenuator (Atma) In Indiana Roadway Maintenance Activities, Yunfeng Chen, Yiheng Feng, Jiansong Zhang Mar 2024

Exploration And Implementation Of Autonomous Truck Mounted Attenuator (Atma) In Indiana Roadway Maintenance Activities, Yunfeng Chen, Yiheng Feng, Jiansong Zhang

Purdue Road School

INDOT reported 153 truck mounted attenuator (TMA)-related accidents between 2016 and 2021. The autonomous TMA (ATMA) removes the driver from the TMA to enhance their safety; however, the functionality and workers’ perception of ATMA must be assessed comprehensively before its implementation in INDOT. This presentation summarizes the findings from 25 closed- road tests and five weeks of field tests of ATMA under four maintenance activities.

Us 33 Over Blue River: Abc’S With Steel, Brandon Arnold, Kurt Heidenreich, Stephanie Wagner

Purdue Road School

The US 33 over the Blue River Bridge Replacement project is the first INDOT project of its kind, and a great example of Accelerated Bridge Construction (ABC). The project used prefabricated steel beam modular super- structure units with prefabricated substructure units, approach slabs, terminal joints, and “steel-like” UHPC for the 8-inch closure pours. Correcting the substan- dard roadway superelevation added complexity to the design and detailing. Join us to learn more.

Assessing The Performance Of Jatropha Curcas And Moringa Oleifera Conditioners Towards Improving Fecal Sludge Treatment For Agricultural Purpose, Doglas Benjamin1 Mar 2024

Assessing The Performance Of Jatropha Curcas And Moringa Oleifera Conditioners Towards Improving Fecal Sludge Treatment For Agricultural Purpose, Doglas Benjamin1

Tanzania Journal of Engineering and Technology (TJET)

been proposed as alternative solutions to replace chemical conditioners for fecal sludge (FS) treatment. However, their effectiveness in treating FS for safe agricultural use has not been thoroughly evaluated. The aim of this study was to assess the suitability of FS treated with Moringa oleifera and Jatropha Curcas conditioners for agricultural use. Physicochemical parameters Indexes, salinity and sodium hazard levels (Wilcox Diagram analysis), and removal efficiency of nutrients and pathogens were evaluated. Qualitative experiments were conducted using dewatering treatment chambers containing untreated control FS samples, FS treated with Moringa oleifera and Jatropha Curcas conditioners at the University of Dar es …

Feature Engineering And Supervised Machine Learning To Forecast Biogas Production During Municipal Anaerobic Co-Digestion, Hunter W. Schroer, Craig L. Just Mar 2024

Feature Engineering And Supervised Machine Learning To Forecast Biogas Production During Municipal Anaerobic Co-Digestion, Hunter W. Schroer, Craig L. Just

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Municipalities with excess anaerobic digestion capacity accept offsite wastes for co-digestion to meet sustainability goals and create more biogas. Despite the benefits inherent to co-digestion, the temporal and compositional heterogeneity of external waste streams creates operational challenges that lead to upsets or conservative co-digestion. Given the complex microbial bioprocesses occurring during anaerobic digestion, prediction and modeling of the outcomes can be challenging, and machine learning has the potential to improve understanding and control of co-digestion processes. Biogas flows are a surrogate for process health, and here, we predicted biogas production from historical data collected by a water resource recovery facility …

Development Of Quantitative Structure Activity Relationships (Qsars) For Predicting The Aggregation Of Tio2 Nanoparticles Under Favorable Conditions, Jaewoong Lee Mar 2024

Development Of Quantitative Structure Activity Relationships (Qsars) For Predicting The Aggregation Of Tio2 Nanoparticles Under Favorable Conditions, Jaewoong Lee

Department of Civil and Environmental Engineering: Faculty Publications

This study developed multi-linear regression (MLR) quantitative structure-activity relationships (QSARs) to predict n-TiO2 aggregation in the presence of high concentrations of representative emerging organic contaminants (EOCs), which presented favorable conditions to interaction with n-TiO2. The largest diameter change (Δ 517 nm at 0 h and Δ 1164 nm at 12 h) of n-TiO2 was observed by estrone, while the smallest diameter change (Δ -114 nm at 0 h and – 4 nm at 12 h) was observed by lincomycin during experimental periods. In addition, the zeta potential changes of n-TiO2 were …

Accuracy Of Nitrate Hysteresis And Flushing For Agricultural Watersheds In The Midwest, Noah Rudko, Sara K. W. Mcmillian, Jane Frankenberger, François Birgand Mar 2024

Accuracy Of Nitrate Hysteresis And Flushing For Agricultural Watersheds In The Midwest, Noah Rudko, Sara K. W. Mcmillian, Jane Frankenberger, François Birgand

Graduate Industrial Research Symposium

Storm event-based metrics, such as hysteresis (HI) and flushing (FI), are used to differentiate nitrate pathways and sources, which is essential for watershed management. Estimations of these event-based metrics typically use high frequency (15-minute – hourly) measurements, but daily data are also used due to their greater availability. To date, there has been no study assessing how using lower frequency samples affect the accuracy of HI and FI, which could skew interpretation of potential nutrient pathways and sources. We used continuous measurements of nitrate collected at 9 watersheds throughout the Midwest spanning 448 storms. HI and FI were estimated from …
