Interactive Simulation of Fire, Burn and Decomposition. (December 2007) Zeki Melek, B.S., Bogazici University; M.S., Bogazici University Chair of Advisory Committee: Dr. John Keyser This work presents an approach to effectively integrate into one unified modular fire simulation framework the major processes related to fire, namely: a burning process, chemical combustion, heat distribution, deco...

Semi-solid processing (SSP) is a popular near-net-shape forming technology for metals, while its application is still limited in titanium alloy mainly due to its low formability. Recent works showed that SSP could effectively enhance the formability and mechanical properties of titanium alloys. The processing parameters such as temperature and forging rate/ratio, are directly correlated with th...

Tropospheric ozone, derived from the Scan-Angle Method (SAM) and the Convective Cloud Differential (CCD) method, exhibits a noticeable abundance over the South Atlantic, where it is associated with biomass-burning in the austral spring. This feature is also seen in the distribution of carbon monoxide observed from Measurements Of Pollution In The Troposphere (MOPITT). In the boreal burning seas...

Context. The lower limit for the mass of white dwarfs (WDs) with C-O core is commonly assumed to be roughly 0.5 M⊙. As a consequence, WDs of lower masses are usually identified as He-core remnants. Aims. However, when the initial mass of the progenitor star is in between 1.8 and 3 M⊙, which corresponds to the so called red giant (RGB) phase transition, the mass of the H-exhausted core at the ti...

At its meeting on September 17, 2002, you asked the National Research Council’s Burning Plasma Assessment Committee (BPAC) to report in December on two aspects of its charge and to comment on whether the United States should reenter the negotiations on the International Thermonuclear Experimental Reactor (ITER), an international burning plasma experiment. This interim report, submitted in respo...

Longleaf pine (Pinus palustris Mill.) forests of the Gulf Coastal Plain historically burned every 2–4 years with low intensity fires, which maintained open stands with herbaceous dominated understories. During the early and mid 20th century however, reduced fire frequency allowed fuel to accumulate and hardwoods to increase in the midstory and overstory layers, while woody shrubs gained underst...

In many contracting settings, actions costly to one party but with no direct benefits to the other (money-burning) may be part of the explicit or implicit contract. A leading example is bureaucratic procedures in an employer-employee relationship. We study a model of delegation with an informed agent, where the principal may impose money-burning on the agent as a function of the agent’s choice ...

Information on the effect of open-field burning of agricultural residues on ambient black carbon (BC) mass and size-resolved particle number concentrations is scarce. In this study, to understand the effect of such open-field burning on short-term air quality, real-time variations of the BC mass and size-resolved particle number concentrations were monitored before and during a corn straw open-...

We report on the spectroscopic and hole burning properties of free-base naphtophthalocyanine with and without 1chloranthracene in polymer host. These materials exhibit a strong 0–0 absorption band in the region 800 nm matching the wavelength range of most semiconductor and Ti:Sapphire lasers. The materials studied feature two persistent hole burning photochemical mechanisms, i.e. one-photon pro...

Understory prescribed burning is being suggested as a viable management tool for restoring degraded oak–pine forest communities in the southern Appalachians yet information is lacking on how this will affect ecosystem processes. Our objectives in this study were to evaluate the watershed scale effects of understory burning on total aboveground biomass, and the carbon and nitrogen pools in coars...
