A time-dependent, spectral, barotropic model and a similar
two-layer primitive equation model are developed to investigate the
planetary-scale wave responses to various types of large-scale
forcing: vorticity and heat sources, and sea surface temperature (SST)
anomalies. Both models are linearized about the zonal mean states of
January climatology.
The characteristics...
This multiple case study explores issues of equity in science education through an examination of how teachers' reasoning patterns compare with students' reasoning patterns during inquiry-based lessons. It also examines the ways in which teachers utilize students' cultural and linguistic resources, or funds of knowledge, during inquiry-based lessons and the...
The purpose of this exploratory study was to examine scientific arguments constructed by secondary science teachers during instruction. The analysis focused on how arguments constructed by teachers differed based on the mode of inquiry underlying the topic. Specifically, how did the structure and content of arguments differ between experimentally and...
A Mobile Ad-hoc NETwork (MANET) is collection of wireless mobile nodes without a network infrastructure or centralized administration. Although MANETs can be used in many applications, such as mobile Internet, military communication, and disaster relief networks, a number of challenges remain. These include routing, medium access control, security, scalability, energy...
The prevalence of Internet-of-Things (IoT) applications leads to an increasing focus on the design and optimization of sensor nodes. Battery lifetime and associated costs of battery replacement often limits the long term operation and viability of sensor nodes. RF wireless energy harvesting on the other hand can be appealing since...
Multiobjective Decision Making (MODM) has been
suggested for the solution of complicated decision
problems. Decision analysis in numerous areas, including
industrial energy and environmental planning, necessarily
requires consideration of multiple conflicting
objectives. MODM has been successfully applied to
a number of these problems of this type. Moreover, it
has the...
This study investigates the evaluation of Return on Investment (ROI) in education from the perspective of high school students, introducing a theoretical model that encompasses both financial and non-financial aspects, with a primary focus on the unique insights provided by high school students. Drawing from a literature review and survey-based...
A typhoon is a highly destructive weather event, causing severe damage and losses to the economy and lives. The impacts of typhoons can be mitigated by adequately predicting their path in advance. The progress of a typhoon can be investigated by analyzing the significant changes in Precipitable Water Vapor (PWV)...
We examined how the experiences of World War II and Korean War veterans,
including prewar, warzone, and postwar factors, affected PTSD symptoms in later life.
This dissertation consists of two studies. In Study 1, four different hypotheses from a
lifespan approach were examined (King et al., 1996): stress evaporation (only...
Let G be a finite group, G₂ be a Sylow 2-subgroup of G, and L/K be a G-Galois extension. We study the trace form qL/K of L/K and the question of existence of a self-dual normal basis. Our main results are as follows: (1) If G₂ is not abelian and...
