Roundabouts have become an alternative for traditional intersections due to the safer operational performance. Previous research has provided crash modification factors (CMFs) as a criterion based on before-after studies as to evaluate the safety performance of roundabouts. One drawback of assessment based on crash modification factors, however, is that a...
Decon Gel 1101, is an uncomplicated, low odor, peelable polymer hydrogel for
use with radiological decontamination, manufactured by Cellular Bioengineer Inc. The
gel allows for single or multiple material applications to contaminated surfaces. As the
gel dries it binds the contaminant by encapsulating and lifting the contaminant into the
gel....
On average there are over 500 forest fires burning more than 3,700 ha each year in South Korea. Between 2014 and 2018, 62 percent of forest fires were multiple fires burning simultaneously in more than two different locations across the country. These multiple fires make it difficult to make decisions...
A transient code (TFETC) for calculating the temperature
distribution throughout the radial and axial positions of a
thermionic fuel element (TFE) has been successfully developed.
It accommodates the variations of temperatures, thermal power,
electrical power, voltage, and current density throughout the
TFE as a function of time as well as...
The purpose of this study was to document vegetation on "The Island", a
Research Natural Area at the confluence of the Crooked River and the Deschutes River in
central Oregon's Juniperus occidentalis Zone and to compare the results with an earlier
study reported in 1964 from 1960-'61 data. Present-day comparisons...
A numerical model for the simulation of fully-coupled fluid-structure
interaction is developed in this study. In modeling the fluid, the Reynolds
Averaged Navier-Stokes equations are solved for an incompressible viscous
fluid field and a k-ε model is employed for turbulence computations.
Hydrodynamic forces obtained by the integration of the fluid...
In networked control systems (NCS) information or packets usually flow from a
sensor or a set of sensors to a remotely located controller. Then the controller
processes the received information and sends a series of control commands to the
actuators through a communication network which could be either wireless or...
AE32000 microprocessor was developed mainly to address the need for the reduction in the amount of memory accesses in embedded applications. One of the primary goals of a computer architect is the design and construction of machines, that support the efficient execution of the programs that will run on them....
High early strength (HES) concrete is becoming increasingly used to repair damaged concrete pavement sections. The use of HES concrete enables the repaired pavement to be opened to traffic within hours of placing the concrete. A common approach used for the rapid repair of concrete pavement consists of closing a...
