Full season navigation and control of ultra-compact autonomous ag-bot in GPS denied environment
No full textThis thesis describes perception and an autonomous navigation system for an ultra-lightweight ground robot in agricultural fields. The system is designed for reliable navigation under cluttered canopies using only a 2-D Hokuyo UST-10LX LiDAR and an RTK GPS as the primary sensors for navigation. Its purpose is to ensure that the robot can navigate through rows of crops without damaging the plants in narrow row-based and high-leaf-cover semi-structured crop plantations, such as corn (Zea mays), sorghum (Sorghum bicolor) and soybean (Glycine max). The fundamental contributions of this work are a GPS-INS based reliable localization system for the robot and a LiDAR-based navigation algorithm capable of rejecting outlying measurements in the point-cloud due to plants in adjacent rows, low-hanging leaf cover, or weeds. Finally, this work describes a behavior-based navigation architecture that enables the system to autonomously traverse a breeding field throughout the planting season.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2020-05-01The student, Karan Chawla, accepted the attached license on 2018-04-27 at 12:05.The student, Karan Chawla, submitted this Thesis for approval on 2018-04-27 at 12:18.This Thesis was approved for publication on 2018-04-27 at 13:38.DSpace SAF Submission Ingestion Package generated from Vireo submission #12540 on 2018-08-31 at 17:30:35Made available in DSpace on 2018-09-04T20:47:32Z (GMT).

Task-Guided and Semantic-Aware Ranking for Academic Author-Paper Correlation Inference
No full textWe study the problem of author-paper correlation inference in big scholarly data, which is to effectively infer potential correlated works for researchers using historical records. Unlike supervised learning algorithms that predict relevance score of author-paper pair via time and memory consuming feature engineering, network embedding methods automatically learn nodes' representations that can be further used to infer author-paper correlation. However, most current models suffer from two limitations: (1) they produce general purpose embeddings that are independent of the specific task; (2) they are usually based on network structure but out of content semantic awareness. To address these drawbacks, we propose a task-guided and semantic-aware ranking model. First, the historical interactions among all correlated author-paper pairs are formulated as a pairwise ranking loss. Next, the paper's semantic embedding encoded by gated recurrent neural network, together with the author's latent feature is used to score each author-paper pair in ranking loss. Finally, a heterogeneous relations integrative learning module is designed to further augment the model. The evaluation results of extensive experiments on the well known AMiner dataset demonstrate that the proposed model reaches significant better performance, comparing to a number of baselines.We would like to thank Yuxiao Dong for suggestions.

INVISIBLE STRUGGLES: EXPLORING CHALLENGES FACED BY WOMEN WITH AMPUTATION IN INDIA
No full textWomen in India, particularly those with amputation, face significant challenges, including but not limited to, unequal prosthetic access and satisfaction, societal discrimination, and the physical and emotional consequences of amputation. These challenges are further exacerbated by gender biases towards access to education and socioeconomic factors, which increases their vulnerability to unemployment and mental health issues. This article emphasizes the urgent need for affordable and customizable prosthetic options tailored to the unique needs of women with amputation, particularly those from low-income backgrounds who often face neglect. Thus, addressing these disparities would significantly enhance their overall well-being and independence.

Nature in children\u27s picture books
No full textThe question addressed by this project is how nature is portrayed in children\u27s picture books. Relevant children\u27s literature was examined for evidence of local ecosystems with plants and animals appropriate to place, and for stories and artwork that invoke the senses through accurate depictions of the natural world. A key influence is Louise Chawla\u27s (2006) research on responsible environmental behaviors. If children are to grow into adults who love and protect the environment, Chawla found that the two key factors are having opportunities to experience the outdoors and having mentors who value the environment. Can teachers and parents use carefully chosen picture books help fill the nature void in children\u27s lives? To demonstrate a model of this type of book, the author of the research wrote and illustrated a picture book about a child\u27s nature discoveries in her local urban environment
