Natural convection heat transfer in air between two vertical
plates 38 by 24 inches was investigated in this work with spacings
between the plates of 0.625, 1.0 and 1.75 inches. One plate was isothermal
and the other adiabatic.
To measure the point velocities in the air layer a very thin...
This report describes the Graphical Editor part of DataLab, a visual programming tool for the specification and synthesis of abstract data types (ADTs). DataLab consists of two major components: graphical editor and source code generator. The graphical editor is used to design an abstract data structure and its operations by...
The influence of surface fields on the breakdown voltage
is studied experimentally for p⁺-n silicon diodes with
a junction depth of 0.5μ in order to improve the curvature-
limited breakdown of the diffused, shallow-collector
junction of a microwave transistor.
Devices with a gap in the gate metal electrode are
also...
Economic methodology is revisited to address issues in
fishery management, and survival analysis is suggested as an
analytical tool to solve the uncertainty problem in
evolutionary economics. Survival analysis can clarify in
statistical terms the impacts of fishery regulation and
economic and biological changes on the fisherman's final
decisions of...
A functional central limit theorem for a strictly stationary
associated random field in the general d-dimension case with an added
moment condition is proven. Functional central limit theorems for
associated random measures are also proven. More specifically,
conditions are given that imply weak convergence in the Skorohod
topology of a...
Simulated Annealing and Threshold Accepting are two stochastic search algorithms that have been successfully used on a variety of complex and difficult problem sets. Due to their stochastic nature they are not guaranteed to produce the same result for each run. This means that these techniques actually produce a distribution...
High-resolution (km in space and hourly in time) surface currents observed by an array of high-frequency radars off Oregon are analyzed to quantify the decorrelation time and length scales of their near-inertial motions. The near-inertial surface currents are dominantly clockwise with amplitudes of 9-12 cm s⁻¹. However, they appear asymmetric...
Massive die-offs of Bufo bufo gargarizans were observed in May 2008 in Mangwal
Gee, Korea. To find out the causes for this disaster several different elements
were examined: pH, total nitrogen, dissolved oxygen (DO), and dissolved heavy
metal, suspension, introduced species, habitat change, disease, temperature
changes, and precipitation and humidity....
The COVID-19 pandemic was thought to be especially difficult for older adults, with high risks for social isolation due to the lockdowns necessitated by the pandemic. This study sought to understand the extent to which these community-residing older adults were receiving and providing social support. Further, we sought to disentangle...
