Electric's Trojan Nuclear Facility is presented. OLAPS
is designed to simulate the thermal-hydraulics of the
primary system including core, steam generators, pumps,
piping and pressurizer. The simulations are based on a
five equation model that...
Yarding delays add significantly to the time and cost required to obtain a given quantity
of timber. In this study, they increased total yarding time by as much as 28 percent. As yarding system complexity increases, the frequency of delays can also be expected to increase. For one balloon yarding...
The purpose of this research study is to investigate and gain understanding of the factors contributing to development of the Center for Advanced Learning (CAL), a regional collaborative educational reform project and the partnerships that emerged from that process. The development process and partnerships are examined from a systems thinking...
Traditionally linear actuator applications are addressed by the use of hydraulic systems. The high maintenance cost and poor reliability will always be the most critical problem in the real applications. Benefited from both the high mechanical advantage of the roll screw and the simple structure of the switched reluctance motor,...
Advanced Very-High Resolution Radiometer 4-km data were collected over the northeast Atlantic for May-August, 1995-1999. Aerosol optical depth was retrieved in cloud-free pixels. In pixels containing clouds from only single-layered, low-level systems, a retrieval scheme that accounts for partly-cloudy pixels was used to retrieve: cloud optical depth, droplet effective radius,...
The appropriate separation of concerns is a fundamental engineering principle. A concern, for software developers, is that which must be represented by code in a program; by extension, separation of concerns is the ability to represent a single concern in a single appropriate programming language construct. Advanced separation of concerns...
A GIS analysis procedure was developed to explore relationships between imagery, yield data, soil information, and other assessments of a field or orchard. A set of conversion utilities, a spreadsheet, and an inexpensive shape file viewer were used to manipulate, plot, and display data. Specific features described include procedures used...
Innovation is a critical component for long term success of an organization. However, being innovative is rarely easy. Successful implementation of any innovation (product, process, or business system) can heavily rely on the functionality of the current innovation system in a given industry. An innovation system is composed of policies,...
The potential for nanomedicine to reduce toxicity and improve therapeutic response to radiation is vast. Clinically, this potential has thus far only begun to be realized with the recent success of the radioenhancing nanoparticle, NBTXR3 by Nanobiotix. Radioenhancing nanoparticles, however, represent only a small class of nanomaterials that may be...
Metallic nuclear fuels have long been studied for use in advanced nuclear reactors, with efforts invested in improving the viability of metallic nuclear fuel elements and overall safety of advanced reactor design concepts. During reactor operations, fuel forms undergo restructuring due to a variety of physical phenomena. Expansion of the...
The implementation of advanced hybrid (Monte Carlo/Deterministic) transport methods for realistic test problems has been a challenge due to the overhead efforts associated with interfacing a solution generated by a deterministic solver with a Monte Carlo based radiation transport code. In this work, with the help of Transpire, Inc., a...
The VISualization of Terrestrial and Aquatic Systems (VISTAS) software development project began with the proposition that visualization would increase the ability of scientists to explore and communicate their data, especially complex datasets that span multiple spatial and temporal scales. A case study of VISTAS articulates how and why scientists intend...
Our oceans surround us, and we depend upon them for food, transportation, and recreation. They affect us daily as they shape our climate and rattle our world with unexpected events. Current headlines indicate that they are in flux and perhaps in trouble. Coral reefs are dying due to rising ocean...
A healthy nation starts with healthy citizens, and participation in sports is one of the most powerful ways to promote healthy habits for a lifetime—not only for physical fitness but also for emotional wellbeing and social cohesion. The natural enthusiasm that children and adolescents (collectively referred to as “youth”) have...
The Laser Gravitational Wave Observatory, or LIGO, is built to observe gravitational waves as they propagate through space. Advanced LIGO is extremely sensitive
to movements of the test mass as small as 10⁻²¹ m/√Hz , which allows many signals other
than gravitational waves to be detected by the system. Pressure...
As manufacturing advancements continue to develop, designers must be able to consider these technologies during the design process. Unfortunately, many of these new technologies, such as additive and advanced joining, have many nuances that require expert knowledge to effectively apply. Additionally, new design techniques, such as topology optimization, allow users...
Policy and research have increased attention in K12 mathematics education on core mathematical practices such as argumentation, justification, and proof, that are central to students learning and doing mathematics. One reason for this increased focus is the empirical evidence that engaging students in mathematical practices provide more equitable opportunities for...

This article outlines results gathered from personal interviews with industry professionals and an industry survey on key...
There are numerous techniques for improving the mixing of fuel and
oxidant species. However, many of these methods cannot be applied to combustion
systems due to material limitations. A means of mixing the reacting species without
physically invading the flow stream is therefore desired.
In this work, induced electromagnetic forces...
