Implementation Of Path Planning Methods To Detect And Avoid GPS Signal Degradation In Urban Environments
… in signal tracking leading to a decrease in navigation performance. These effects are modeled into the simulation environment and are used as part of the path planning algorithm to provide better navigation strategies. This thesis aims to provide an implementation of A* algorithm in …

Cross-Modal Interface Design in Crisis Control Systems: The Role of Gender
… with computer touch display interfaces, navigation through virtual environments (VE) and language in computer-mediated communication. In these previous studies, gender differences were found in the use of words and language in computer-mediated communication and in navigation strategies …

Seeking Sisterhood: An Exploratory Qualitative Inquiry into the Sorority Rejection Experiences of Black Women
… and participants' post-rejection social navigation strategies. Student affairs practice implications address institutions' responsibility to create interventions and support structures for Black women students outside peer-led groups like Black Greek-letter organizations. Black sororities …

How Women’s College Student Involvement Contributes to Their Career Aspirations and Navigation for Success in Technology Startup Organizations
… to career aspirations. As related to career navigation strategies, sorority membership, student government experience, and again, internships were important contributors to acquiring navigation skills and strategies. The participants listed general education courses as the least helpful …

An Examination of Hippocampal and Prefrontal Contributions to Spatial Learning and Memory using Immediate Early Gene Imaging
… encode and ultimately rely on for accurate navigation in this task remains unclear. Therefore, the primary objectives of this thesis were to conduct an in-depth investigation into the use of navigation strategies during memory encoding and retrieval in the water maze, and to characterise the …

A*-Based Path Planning for an Unmanned Aerial and Ground Vehicle Team in a Radio Repeating Operation
… non-line-of-sight conditions and naive navigation strategies can cause substantial degradations in radio link quality. Therefore, this thesis incorporates an unmanned aerial vehicle as a radio repeating node and presents a path planning strategy to cooperatively navigate the vehicle team …

An alternative audio web browsing solution: viewing web documents through a tree structural approach
… guide the user accordingly. A number of browsing/navigation strategies are presented to offset these problems. These are implemented through WebTree. This is a highly customisable web browser which rcnders documents through a dynamically expandable tree structural view. This mirrors the …

Region-specific Mechanisms of Estrogen and Age on Neuronal Ensemble Activity During Spatial Navigation
<p>Estradiol modulates the use of spatial navigation strategies in female rats. The presence of circulating estradiol enhances learning on tasks that require the use of a hippocampus-dependent place strategy and impairs learning on tasks that require the use of a dorsal striatum-dependent response …

Development and Testing of a Steerable Cruciform Parachute System
… identified earlier. Furthermore, the precision navigation potential of the system must be demonstrated; specifically, the system must be capable of arriving closer to the desired impact point on the ground than an unguided system dropped under the same conditions. The work described in this …

Parietal dysfunction in children with prenatal alcohol exposure
… confirm that boys and girls use different navigation strategies that rely on different brain regions and suggest that the regions used by boys are more susceptible to alcohol damage, while the regions used by girls are relatively spared. In conclusion, all the tasks investigated showed …

Robotic Olfactory-Based Navigation with Mobile Robots
… source is designing an effective olfactory-based navigation algorithm, which guides the robot to detect emitted odor plumes as cues in finding the source. This dissertation proposes three kinds of olfactory-based navigation methods to improve search efficiency while maintaining a low computational …

Navigating a normative world: a social psychological exploration of the experiences and identities of trans and/or non-binary adolescents and parents in the UK
… from a number of sources, and that a range of strategies, including disclosure negotiation, cognitive structuring and proactive protection, are used to navigate this environment. The findings shed light on the school experiences of gender-diverse adolescents, and suggest that the British school …

Understanding and Improving Distal Pointing Interaction
… require very high precision. We analyzed user navigation strategies and found that the high precision techniques afford users to remain stationary while performing interactions. However, we also found that individual differences have a strong impact on the decision to walk or not, and that, …

Organization of spatiotemporal information and relational memory in the hippocampus
… memory in organizing episodic memory during navigation and reconstruction. Navigation is a critical component in most organisms’ survival. Reconstruction, on the other hand, provides an incredibly rich method of evaluating the precise information remembered by an individual after attempting …
