The Development and Evaluation of a Cumulative Exposure Integration Method Based on Fatigue Failure Theory
(2018-12-07)
Cumulative exposure to physical risk factors has been identified as one of the major contributors to the development of workplace musculoskeletal disorders (MSDs). Linear integration methods have been widely used to quantify ...
Coupling GPS/INS and IMM Radar Tracking Algorithms for Precise Collaborative Ground Vehicle Navigation
(2018-12-07)
This thesis describes a method of collaborative ground vehicle navigation utilizing shared
radar data to provide observations during periods of GPS degradation. Navigational errors that
typically arise from degraded GPS ...
The Effect of Formal Mentoring Programs on Persistence of College Sophomores
(2018-12-06)
Retention has been an issue in higher education for decades (Freedman, 1956; Noel et al., 1986; Tinto, 1987, 2012). Many attempts have been made to address this issue, with most research focusing on the freshman year. ...
Effectiveness of Home Gardening in Reducing Food Insecurity and Improving Health in Chacraseca, Nicaragua: A Pilot Study
(2018-12-06)
Nicaragua has a high rate of food insecurity determined by factors such as, poverty, employment, education, social capital and climate change. Home gardening and nutrition education can decrease food insecurity and improve ...
Obstacle Avoidance of an Unmanned Ground Vehicle using a Combined Approach of Model Predictive Control and Proportional Navigation
(2018-12-06)
This thesis presents a new approach for the guidance and control of a UGV (Unmanned
Ground Vehicle). A special focus was placed on moving obstacles that interfere with the
planned path of the vehicle, this is due to the ...
