Investigating Surface Performance Trade-offs of Unimpeded Taxiways

Optimizing usage of unimpeded taxiways is a near-term operational change to mitigate emission impact on aviation and increase efficiency at airports. An unimpeded taxiway is a path for an aircraft to taxi around an active runway. Unimpeded taxiways provide benefits such as increased departure throughput, increased safety, reduced surface congestion, more efficient taxi-in procedures, and thereby also yield environmental benefits. The goals of this work are to investigate the use of current taxiways, examine surface performance and fuel burn trade-offs, and to develop a decision-support model based on potential fuel savings of unimpeded taxiways. This study analyzes unimpeded taxiway use at Hartsfield-Jackson International Airport (ATL), Dallas/Fort-Worth International Airport (DFW), and Detroit Metro Airport (DTW) using ASDE-X data from 10 September 2012 to 28 February 2013. The trends and patterns of aircraft taxi routes show the unimpeded taxiway is used the most during peak arrival and peak departure hours. This study provides decision-makers at the operations level a practical guidance tool with the necessary information to effectively use unimpeded taxiways and conventional taxiways from an environmental perspective. Decision rules were developed to maximize fuel savings. The decision scenario analysis concluded that the most promising decision rule at ATL, DFW, and DTW to yield the most environmental benefit is based on multiple factors. The multi-factor decision rule based on terminal destination, arrival time, and aircraft type resulted in an average aircraft fuel savings of 8.1% to 20.4%

The Impact of Adult Attention Deficit Hyperactivity Disorder Symptoms on Maternal Parenting Behaviors

The purpose of this qualitative research project is to examine the impact of maternal ADHD symptoms on managing the responsibilities related to parent-ing. The primary researcher conducted three interviews with mothers who exhibit ADHD symptoms in order to gain insight into their perceived difficulties related to the disorder. Analysis of the data indicates these mothers have diffi-culty completing tasks, are disorganized, and are easily overwhelmed with the responsibilities of parenting resulting in difficulty managing their own behavior and being consistent in disciplining their children. Due to these areas of defi-ciency, it is suggested the presence of maternal ADHD symptoms results in less than optimal parenting behaviors, which could result in negative out-comes for children

MoMA and Nazi-Era Art Restitution: Contexts and Thoughts for the Future

Holocaust-era restitution remains one of many issues troubling the museum world in recent years. These types of cases expose the persistent concern over ownership of the material culture held within museums that, in part, make up the philosophies and cultural traditions underlying them. In the wake of the 1998 Washington Conference on Holocaust-Era Assets, the American museum community asserted they could properly regulate restitution claims without need for an independent commission, as was being established in many European countries at the time. This thesis reflects upon developments following 1998 and assesses the current value systems of American museums and their commitment to the international issue of restitution by examining the actions and policies of the Museum of Modern Art (MoMA) in New York City. Since the establishment of the Washington Conference Principles, museums holding Nazi-era misappropriated works have continually tried to mischaracterize applicable policy. MoMA has not only experienced difficulties resulting from its early acquisitions, but in recent years, it has been very visible in a series of recent restitution claims and debates. This thesis argues that MoMA could set a different example, through its statements and actions, for Holocaust-era restitution by acknowledging its historical complicity and urging other institutions and the public to go beyond notions of possession. MoMA is an institution that has undoubtedly become more complex and internationally implicated in the past few years. However, the issue of restitution and its inadequate treatment in the United States has brought into scrutiny museums like MoMA, impacting upon the public’s willingness to place confidence in the museum in its role as trustee of works of art. I contend that, should MoMA wish to maintain its position of influence in the museum system in the United States and abroad, it needs to become more invested in the future and be conscious of how it is transmitting memory and the meaning of the past to an increasingly transnational and diverse public. Although this case study examines the treatment of Nazi-looted art in one American institution, the issues under consideration have transferable moral significance across the larger debate of stolen cultural property

Physics Students' Mindsets and Their Impact on Learning and Perceived Satisfaction

Characterizing a mindset landscape within the physics classroom is crucial to portray the variation and context of mindset in the classroom. This paper will be looking at students enrolled in Oregon State University’s PH20x series, which is a series of three algebra-based introductory physics courses. This project is an exploratory model which intends to obtain data on students’ fixed or growth mindsets through mixed methods. The approach will utilize a three-pronged method to get an in-depth, yet large scope of understanding of students’ mindsets. This will be achieved by conducting interviews on several students, supplemented with a follow-up email to explore whether having a fixed or growth mindset leads to greater outcomes or perceived satisfaction. Interviews were analyzed utilizing Angie Little’s Codebook [1]. For a broader understanding of the student population, a Likert scale will be distributed to all students within the class. Themes of context and conditional dependency emerged during the analysis of the transcripts. Contextual dependency seems to affect both mindset and response, and applicability to the future was seen as the greatest influence in transcripts showing contextual dependency. For students showing a conditionally dependent mindset, performance is a large component in dictating a student’s response to challenge.Keywords: physics, mindset theory, motivation, fixed, growth, satisfaction, learning, implicit, entity, incrementa

SegICP: Integrated Deep Semantic Segmentation and Pose Estimation

Recent robotic manipulation competitions have highlighted that sophisticated robots still struggle to achieve fast and reliable perception of task-relevant objects in complex, realistic scenarios. To improve these systems' perceptive speed and robustness, we present SegICP, a novel integrated solution to object recognition and pose estimation. SegICP couples convolutional neural networks and multi-hypothesis point cloud registration to achieve both robust pixel-wise semantic segmentation as well as accurate and real-time 6-DOF pose estimation for relevant objects. Our architecture achieves 1cm position error and <5^\circ$ angle error in real time without an initial seed. We evaluate and benchmark SegICP against an annotated dataset generated by motion capture.Comment: IROS camera-read

Filling Jars to Measure Time

If water is flowing at the same constant rate through each of H>3 hoses, so that any one hose will fill any one of J>2 available jars in exactly one hour, then what are the fillable fractions of a jar, and what are the measurable fractions of an hour? Learning to systematically answer such questions will not only equip readers to fluently use fractions, but also introduce or reintroduce them gently to the Queen of Mathematics – Number Theory

Lessons Learned in the Early Stages of a Community-Academic Partnership to Address Health Disparities in a Rural Community

In rural Georgia, African American men are burdened by chronic health diseases such as cancer, diabetes, and cardiovascular disease. Community-academic partnerships that leverage community-based participatory research (CBPR) principles can facilitate the adaptation and translation of multilevel programs to address chronic disease prevention and management in rural areas. The objective of this study was to explore key components of the CBPR process that bolstered the early stages of a partnership established between rural-residing community leaders and academic partners in Georgia. Qualitative methodology was used to collect and assess data regarding the initial engagement between the community and academic partners. Findings indicate that five components supported initial engagement: utilizing the public service and outreach arm of the university to connect with rural communities; creating synergy around identified community health needs; encouraging community members to provide input into the research design to ensure the research goals reflect community values; enhancing the capacity of community partners; and following the lead of the community. Findings provide insights into how to begin engaging rural communities in the southeast in order to strengthen the adaptation and translation of initiatives to improve cancer, diabetes and cardiovascular disease outcomes
