Fatigue And Its Management In The Aviation Industry, With Special Reference To Pilots, Rajee Olaganathan, Timothy B. Holt, Jackie Luedtke, Brent D. Bowen

Publications

Abstract Fatigue is a significant contributing factor that reduces human ability and leads to accidents and threatens the safety of aircraft and human lives. Approximately 70% of fatal accidents that occur in commercial aviation operations are due to human factors. More specifically, crew fatigue contributes to nearly 15 to 20% of the accidents (Akerstedt, 2000). These accidents and incidents are associated with pilot fatigue because of the long duty periods, disruption of circadian rhythms, and inadequate sleep that are common among both commercial and military pilots. Though fatigue is seen in all the disciplines associated with the aviation industry, this …

Knowledge Infused Policy Gradients For Adaptive Pandemic Control, Kaushik Roy, Qi Zhang, Manas Gaur, Amit P. Sheth

Publications

COVID-19 has impacted nations differently based on their policy implementations. The effective policy requires taking into account public information and adaptability to new knowledge. Epidemiological models built to understand COVID-19 seldom provide the policymaker with the capability for adaptive pandemic control (APC). Among the core challenges to be overcome include (a) inability to handle a high degree of non-homogeneity in different contributing features across the pandemic timeline, (b) lack of an approach that enables adaptive incorporation of public health expert knowledge, and (c) transparent models that enable understanding of the decision-making process in suggesting policy. In this work, we take …

Building Participatory Counternarratives: Pedagogical Interventions Through Digital Placemaking, Jordan Frith, Jacob Richter

Publications

Places are filled with stories, with histories that shape how people understand the nature of a place. Places are unique sets of trajectories – each with a story – coming into contact. However, just as much as places are defined by their histories, they are also shaped by the histories that are forgotten, or far too often, actively suppressed through dominant narratives. After all, dominant media of spatial, public memory – for example, plaques and public monuments – often reproduce dominant narratives of a place, narratives created by the powerful. This project examines how digital placemaking can be deployed through …

Creation Of Male-Sterile Lines That Can Be Restored To Fertility By Exogenous Methyl Jasmonate For The Establishment Of A Two-Line System For The Hybrid Production Of Rice (Oryza Sativa L.), Haksong Pak, Haoyi Wang, Yusin Kim, Unchol Song, Mengxin Tu, Dezhi Wu, Lixi Jiang

Publications

Male sterility is widely used in the production of hybrid seeds in rice, but the use of genic male sterility is limited because of the high labour cost for maintaining male-sterile lines. Previous studies using T-DNA insertional mutagenesis demonstrated that disrupting the expression of oxophytodienoic acid reductase 3 (OPR3), which is involved in the jasmonate biosynthesis pathway, results in a kind of male sterility that can be restored to fertility by exogenous jasmonate in Arabidopsis. Here, we created male-sterile mutations by editing the second and fourth exons of OsOPR7 in rice through clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated system …
