Online survey data collection is becoming popular because it provides benefits in cost, ease of collecting and managing data, flexibility in format, and access to a diverse population. Surveys are often used for health studies such as Oregon State University’s WAVE Project, which utilizes the WavePipe system, a server enabling...
As the number of students and faculty involved in online learning in recent decades has increased, we recognize that there is a limited understanding of how learners react, interact, behave, and are served by the various components in the information delivery processes. When learning online without an instructor present in...
The performance of an over 10 times larger microbial fuel cell (MFC) with double cloth electrode assembly (CEA) during 63 days of continuous operation demonstrates that the excellent performance of CEA-MFC can be further improved during scale-up. With a new separator material and U-shaped current collectors, the larger MFC produced...
Organic semiconductors have attracted considerable attention due to their applications in low-cost, solution-processable (opto)electronic devices. An important class of high-performance organic semiconductors is pentacene derivatives, which exhibit high charger carrier mobilities in field-effect transistors and ultrafast singlet fission in photovoltaic devices. These derivatives have served as benchmark materials for systematic...
Sodium-ion batteries are emerging as a highly promising technology for large-scale energy
storage applications. However, it remains a significant challenge to develop an anode with
superior long-term cycling stability and high-rate capability. Here we demonstrate that the
Na⁺ intercalation pseudocapacitance in TiO₂/graphene nanocomposites enables high-rate
capability and long cycle life...

The phragmoplast associated kinesin, PAKRP2, from the model organism Arabidopsis thaliana is categorized as an orphan, or ungrouped, kinesin due to structural divergences from the established 14 kinesin families. An early study on PAKRP2 found that it localized to the phragmoplast mid zone during the late stages of cell division...
Reliability of sub-micron analog circuits is directly related to impact ionization and
the subsequent changes in threshold voltage and drain current of n-MOSFET devices.
This thesis presents theory of the hot-electron effects on the device characteristics and
circuit performance, explores several approaches to improve performance at both the
device and...
This dissertation presents nonlinear terahertz (THz) properties of carbon nanomaterials investigated by time-resolved high-field THz spectroscopy. In order to determine THz characteristics of nanomaterials, we performed THz power spectrum measurement, THz raster imaging, THz time-domain spectroscopy (THz-TDS) and time-resolved pump-probe experiment on two different types of single layer graphene and...
The new Technical Report Management System (TRMS) is a client/server web application developed for the Compute Science Department. It provides web services like online browsing, viewing, searching and online database administration including creating and modifying the existing bibliographic records. It is a multi-tiered, component-based application that deploys the latest J2EE...
In this comprehensive thesis, we present a series of experiments and findings that highlight the
critical importance of TDC Voltage Sensors in the hardware security domain. Our research begins
by introducing a novel self-calibrating module, demonstrating its efficiency through preliminary
calibration tests. We then delve into the Peak-to-Peak tests, which...
