Turbulence in Natural Environments
… subsets of this general problem of turbulence in natural environments- in the context of neutral and thermally stratified atmospheric surface layer, the presence of a heterogeneous vegetation canopy and the interaction between air flow and a static water body in presence of flexible protruding …

Foliage Echoes and Sensing in Natural Environments
Foliage is very common feature in the habitats of echolocation bats and thus its echoes constitute the major input of bats' sensory systems. Acquiring useful information from vegetation echoes facilitates the bats significantly in the navigation and foraging behaviors. To better understand the …

Molecular mechanisms of microbial interactions in model systems and natural environments
… molecular mechanisms of interactions directly in natural communities. In Chapter 3, I studied metabolic capabilities and interactions of 52 novel heterotrophic bacteria isolates capable of utilizing phytoplankton-derived organic matter from the Equatorial Pacific. I generated and analyzed closed …

Scalable recognition of human activities for pervasive applications in natural environments
… is critical for systems intended to be used in natural settings, particularly, for those that require long-term deployment at a large-scale. This thesis addresses these problems by proposing an activity recognition framework that uses an incremental learning paradigm. The proposed framework …

Location Finding in Natural Environments with Biomimetic Sonar and Deep Learning
… sonar can be used to navigate in GPS-denied environments, and can be an important sensor used in a scenario when other sensors meet constraints, like in the sensor fusion applications.

Machine Learning Approaches for Biosonar Systems: Investigating Dynamic Sensing in Complex Natural Environments
… new approaches for acoustic sensing in complex environments, while the differential performance across signal types provides insights into the evolutionary pressures shaping biosonar systems. The work establishes machine learning as a powerful tool for uncovering subtle patterns in seemingly …

Investigating the impact of exposure to degraded natural environments on working memory through photographic stimuli
… in nature or in other ways become immersed in natural surroundings. However, beyond the fact that a good number of studies often use only photographic stimuli to simulate nature exposure, they have employed nature stimuli that are high in valence and low in arousal, as well as used urban …

A Seasonal Study of the Pituitary-Gonadal-Adrenal Axes in Peromyscus Leucopus from Natural Environments
Since Elton’s account and description of population cycles in 1924, a vast amount of research has been undertaken to ascertain what animals have three to four ye a r cyclic fluctuations and what mechanisms are responsible for these seemingly predictable changes. For many years the spectacular …

Early Head Start and Early Intervention: A Collaborative Approach to Serving Infants and Toddlers With Disabilities in Natural Environments
The purpose of this study was to determine the degree to which children with Part C IFSPs are served by Early Head Start programs (funded in Wave 1 and 2). In addition, the settings that Wave 1 and Wave 2 Early Head Start programs use to serve infants and toddlers were examined. Finally, this study …

Into the Wild: Deploying Brain and Physiological Sensing in Natural Environments to Enhance Wake and Sleep Cognitive Behavioral Studies
… for performing cognitive behavioral studies in natural settings: one for wake time and one for sleep. The equipment utilized today in behavioral and sleep labs is not very accessible, comfortable, portable, or simple to operate. The systems documented in this dissertation demanded the creation …

Parsimonious Biosonar-Inspired Sensing for Navigation Near Natural Surfaces
Achieving autonomous in complex natural environments has the potential to transform society by bringing the benefits of automation from the confines of the factory floor to the outdoors. There, it could benefit areas such as environmental monitoring and clean-up, precision agriculture, delivery of …

Foraging in a Complex World: From Individual Flight Performance to Collective Behavior in Bumblebees (Bombus Impatiens)
… to explore how insects cope with challenging, natural environments, scaling from individual performance to group dynamics. First, I explore how bumblebee foragers cope with structural clutter, with particular emphasis on the allometry of maneuverability and flight performance (Chapter 1). Next, …

The Role of an Urban Waterfront - Rethinking the Shanghai Bund
… interface between nature and the built and human environments. Researching both theoretical and practical resources could be helpful in determining their prospective roles and benefits. Instead of being used solely as a public space, it should be a site that combines urban and natural …
