Structure elucidation of bioactive natural products from Madagascar marine algae and cyanobacteria

Creator:: Andrianasolo, Eric Hajaniriana
Abstract:: This thesis is an investigation of the natural products deriving from marine algae and cyanobacteria and has resulted in the discovery of eleven new secondary metabolites. The structure elucidations of these new molecules were performed using a variety of spectroscopic techniques. Four new macrolides were isolated and characterized from the...

Image features and learning algorithms for biological, generic and social object recognition

Creator:: Zhang, Wei
Abstract:: Automated recognition of object categories in images is a critical step for many real-world computer vision applications. Interest region detectors and region descriptors have been widely employed to tackle the variability of objects in pose, scale, lighting, texture, color, and so on. Different types of object recognition problems usually require...

Perceptions of High School Student Athletes and Non-Athletes, Teachers, and Administrators Relevant to the Drug and Alcohol Prevention Policy: A Case Study

Creator:: Hess, Ashleigh E.
Abstract:: In public high schools, drug and alcohol prevention programs and policies have been ineffective in their deterrence of drug and alcohol use and abuse (Skager R., 2007). It is important to consider the needs of students and to create an effective, student centered drug and alcohol prevention program and policy....

Effect of Active Trailing Edge Motion Upon Airfoil Energy Harvester

Creator:: Strahl, Jordan D.
Abstract:: The application of a flapping foil with prescribed trailing edge motion to energy harvesting in a low reduced frequency (k = fc/U∞) regime was experimentally studied. The effects of the phase and amplitude of the applied trailing edge motion upon time-variant power extraction capability have been measured and are interpreted....

Gender bias & teachers : college students' perceptions of sexual discrimination in their high school

Creator:: Hostetler, Catherine L.
Abstract:: The field of gender bias indicates that teachers are a significant source of gender-role socialization for students. This study focuses on post hoc recollections of college students' perceptions of gender bias exhibited by their high school teachers. Specifically, this study asks students to define sex discrimination, as well as describe...

A nano-power wake-up circuit for RF energy harvesting wireless sensor networks

Creator:: Lindsley, Christopher J.
Abstract:: A fully integrated CMOS latched comparator is presented for use as a wake-up circuit that is attached to an RF energy harvester in a battery free wireless sensor network. The system consumes less than 36nA static current at 20°C and dissipates 2pJ of energy per conversion. The comparator comprises of...

Design techniques for clocking high performance signaling systems

Creator:: Hanumolu, Pavan Kumar
Abstract:: Scaling of CMOS technology has progressed relentlessly for the past several decades. In order for this unprecedented scaling to benefit the performance of large digital systems, the communication bandwidth between integrated circuits (ICs) must scale accordingly. However, interconnect technology does not scale as aggressively, making communication between chips the major...

Lift Enhancement of Pliant Wings Through Bio-Mimicry

Creator:: Osterberg, Nathaniel Brent
Abstract:: Flexible aerodynamic surfaces have been shown to favorably influence flight characteristics at low Reynolds numbers by increasing lift, angle of attack at stall, and resistance to perturbation. The objective of the research presented within this thesis is to investigate the influence of two aspects of flight observed in biological flyers,...

Fluidic and thermal modeling for the high production rate synthesis of high quality nanoparticles

Creator:: Peterson, Daniel Alan
Abstract:: Advances of colloidal nanomaterials for societal benefit have been hampered by the high cost and low quality of nanoparticles (NPs). The production of high quality nanoparticles within colloidal suspension has two related concerns; (1) current high production rates methods of synthesizing nanoparticles result in a larger range of particle size,...

Synthetic studies toward a total synthesis of paeoniflorigenin

Creator:: Hong, Zhenqiu
Abstract:: A new approach towards a total synthesis of paeoniflorigenin is discussed. The approach involves the application of regio- and stereoselective [2+2] photocycloaddition for the preparation of a key intermediate, cyclobutanone 86, and model studies on diiodosamarium (Sm12) mediated pinacol coupling of a diketone. Intermolecular [2+2] photocycloaddition of a,13unsaturated lactam 33...
