Assessment Of Different Methods For Shadow Detection In High-Resolution Optical Imagery And Evaluation Of Shadow Impact On Calculation Of Ndvi And Evapotranspiration, Mahyar Aboutalebi, Alfonso F. Torres-Rua, William P. Kustas, Héctor Nieto, Calvin Coopmans, Mac Mckee

AggieAir Publications

Significant efforts have been made recently in the application of high-resolution remote sensing imagery (i.e., sub-meter) captured by unmanned aerial vehicles (UAVs) for precision agricultural applications for high-value crops such as wine grapes. However, at such high resolution, shadows will appear in the optical imagery effectively reducing the reflectance and emission signal received by imaging sensors. To date, research that evaluates procedures to identify the occurrence of shadows in imagery produced by UAVs is limited. In this study, the performance of four different shadow detection methods used in satellite imagery was evaluated for high-resolution UAV imagery collected over a California …

Analyzing Large Workers’ Compensation Claims Using Generalized Linear Models And Monte Carlo Simulation, Fatemeh Davoudi Kakhki, Steven Freeman, Gretchen Mosher

Faculty Publications

Insurance practitioners rely on statistical models to predict future claims in order to provide financial protection. Proper predictive statistical modeling is more challenging when analyzing claims with lower frequency, but high costs. The paper investigated the use of predictive generalized linear models (GLMs) to address this challenge. Workers’ compensation claims with costs equal to or more than US$100,000 were analyzed in agribusiness industries in the Midwest of the USA from 2008 to 2016. Predictive GLMs were built with gamma, Weibull, and lognormal distributions using the lasso penalization method. Monte Carlo simulation models were developed to check the performance of predictive …

Implementation Of Music In A Simulated Unmanned Aircraft System (Uas) Monitoring Task To Alleviate The Vigilance Decrement, Maria Chaparro

Theses and Dissertations

The vigilance decrement is a thoroughly researched phenomenon in psychological literature and has been identified in many monotonous tasks. Although the phenomenon has been recorded for approximately 80 years, no universal repair, or theory to account for its onset, has been identified. Jobs requiring monotonous task performance have been increasing as time has elapsed, in part due to the rise in automation. Furthermore, much of the vigilance literature does not address modern, more complex tasks, such as the Unmanned Aerial Systems (UAS) monitoring task. A potential method that has been proposed to combat the vigilance decrement is the inclusion of …

Since March, 2017, the cost of denied boarding began to draw the attention of all Brazilian airlines because of the Resolution 400 of the Brazilian National Civil Aviation Agency. This Resolution covers several items but here we will focus on the penalty that the airlines need to pay for each passenger who had his boarding denied involuntarily in domestic flights.

An operating restriction of an airline may result in the denial of boarding of a specified number of passengers. When this process of selecting the passengers and their accommodation on another flight happens very close to the time of departure, …

The Relationship Between Teamwork Knowledge And Teamwork Behavior, Jeeun Yi, Glenn E. Littlepage

River Cities Industrial and Organizational Psychology Conference

Many organizations utilize a team-focused work structure in the workplace. Researchers have studied how working as a team can improve organizational outcomes such as productivity and employee satisfaction (Katzenbach & Smith, 1993). However, not all teams make positive outcomes (Hackman, 1998). Previous research has shown that effective teamwork can facilitate group and organizational effectiveness (Salas, Stagl, Burke, & Goodwin, 2007). Various models of teamwork process have been developed (Marks, Mathieu, & Zaccaro, 2001; Rousseau, Aube, & Savoie, 2006; Salas, Sims, & Burke, 2005). A meta-analysis found a consistent relationship between the ten dimensions of teamwork identified by Marks et al. …
