Strategy Design For Community Response To Distress And Decline Using Data Analytics, Michael P. Johnson Jr.

Michael P. Johnson

The foreclosure crisis in the U.S. has resulted in immense economic and social losses for individuals and neighborhoods. Some neighborhoods face long-term declines in population and economic activity that have been compounded by the foreclosure crisis. How can government and non-profit organizations design responses to neighborhood distress that reflect distinctive community characteristics and are consistent with long-term policy and planning goals? In this talk, I discuss alternative decision modeling strategies that support neighborhood health. Where foreclosure responses are likely to ensure that neighborhoods remain vital places for residential housing, productive strategies may include property acquisition and redevelopment. Other neighborhoods ...

Plutonium Worlds. Fast Breeders, Systems Analysis And Computer Simulation In The Age Of Hypotheticality, Sebastian Vehlken

communication +1

This article examines the media history of one of the hallmark civil nuclear energy programs in Western Germany – the development of Liquid Metal Fast Breeder Reactor (LMFBR) technology. Promoted as a kind of perpetuum mobile of the Atomic Age, the "German Manhattan Project" not only imported big science thinking. In its context, nuclear technology was also put forth as an avantgarde of scientific inquiry, dealing with the most complex and 'critical' technological endeavors. In the face of the risks of nuclear technology, German physicist Wolf Häfele thus announced a novel epistemology of
"hypotheticality". In a context where traditional experimental engineering ...

A Stochastic Model For Self-Scheduling Problem, Lili Zhang 2014 University of Tennessee, Knoxville

A Stochastic Model For Self-Scheduling Problem, Lili Zhang

Masters Theses

The unit commitment (UC) problem is a typical application of optimization techniques in the power generation and operation. Given a planning horizon, the UC problem is to find an optimal schedule of generating units, including on/off status and production level of each generating unit at each time period, in order to minimize operational costs, subject to a series of technical constraints. Because technical constraints depend on the characteristics of energy systems, the formulations of the UC problem vary with energy systems. The self-scheduling problem is a variant of the UC problem for the power generating companies to maximize their ...


Potential To Increase Indigenous Biodiesel Production To Help Meet 2020 Targets – An Eu Perspective With A Focus On Ireland, Fionnuala Murphy 2014 SelectedWorks

Potential To Increase Indigenous Biodiesel Production To Help Meet 2020 Targets – An Eu Perspective With A Focus On Ireland, Fionnuala Murphy

Fionnuala Murphy

The biofuels penetration rate target in Ireland for 2013 is 6% by volume. In 2012 the fuel blend reached 3%, with approximately 70 million litres of biodiesel and 56 million litres of ethanol blended with diesel and gasoline respectively. For January and February 2013, the blend rate had only reached 2.7%. The target of 10% by 2020 remains which equates to approximately 420 million litres. Achieving the biofuels target would require 345 ktoe by 2020 (14,400 TJ). Utilising the indigenous biofuels outlined in this paper leaves a shortfall of approximately 12,000 TJ or 350 million litres (achieving ...

A Set Union Based Formulation For Course Scheduling And Timetabling, Jesse Paul Bukenberger

Master's Theses and Project Reports

The Course Timetabling Problem is a widely studied optimization problem where a number of sections are scheduled in concert with the assignment of students to sections in order to maximize the desirability of the resulting schedule for all stakeholders. This problem is commonly solved as a linear program with variables for each student or group of students with identical schedules. In this paper we explore an alternative formulation that aggregates binary student variables into integer variables denoting the number of students enrolled in a course. Our solution method assumes decomposition of the general schedule into time blocks, and applies a ...


Analysis Of Environmentally Friendly Marking Ink For Military Equipment And Electronics, Liang Li 2014 California Polytechnic State University

Analysis Of Environmentally Friendly Marking Ink For Military Equipment And Electronics, Liang Li

Master's Theses and Project Reports

Recent advancements in corrosion-resistance coating technology has reduce the use of environmentally harmful compounds such as Hexavalent Chromium by replacing Hexavalent Chromium in primers and topcoat. However, marking inks were neglected in the process. Products such as Enthone 50 series are still widely used, which contain compounds such as lead, hexavalent chromium, bisphenol A (BPA), Cadmium Sulfide, and more. Excluding catalyst compositions in Enthone, the chemicals in the ink alone contained three reproductive toxicant and numerous carcinogens. Therefore, it was essential to search and validate the performance of potential marking ink that would meet the standards in military applications.

Leveraging High Resolution Signalized Intersection Data To Characterize Discharge Headway Distributions And Saturation Flow Rate Reliability, Stephen M. Remias, Alexander M. Hainen, Gannon Grimmer, Alexander D. Davis, Christopher M. Day, Thomas M. Brennan Jr, James R. Sturdevant, Darcy M. Bullock

JTRP Other Publications and Reports

As highway systems become more congested, it becomes increasingly important to understand the reliability with which we can estimate important performance measures such as volume to capacity ratios, particularly as we move toward leveraging field infrastructure to obtain real-time performance measures. In 1947, Greenshields wrote a paper that characterized “green time consumed” by “car-in-line-number” that ultimately was called headway. Average headway is one of principles used by the highway capacity manual to estimate saturation flow rate at signalized intersections. However, the current analytical techniques calculate a deterministic value for saturation flow rate that does not consider the stochastic variation of ...
