The objective of the laboratory study is to examine the conditions under which transition metal ions (e.g., ferrous ion, Fe2+) could activate the persulfate anion (S2O8(2)-) to produce a powerful oxidant known as the sulfate free radical (SO4-*) with a standard redox potential of 2.6 V. The SO4-* is capable of destroying groundwater contaminants in situ(More)
In situ chemical oxidation (ISCO) is a technique used to remediate contaminated soil and groundwater systems. It has been postulated that sodium persulfate (Na2S2O8) can be activated by transition metal ions such as ferrous ion (Fe2+) to produce a powerful oxidant known as the sulfate free radical (SO4-*) with a redox potential of 2.6 V, which can(More)
While early research on real-time computing was concerned with guaranteeing avoidance of undesirable effects such as overload and deadline misses, adaptive real-time systems are designed to handle such effects dynamically. Various research efforts have addressed the characterization and improvement of the dynamic behavior of real-time systems. However, to(More)
Radio frequency heating (RFH) is a technology that increases the cost-effectiveness of a variety of site remediation technologies by accelerating the rate of contaminant removal. Heating makes the physical, chemical, and biological properties of materials such as contaminants, soil, and groundwater more amenable to remediation. RFH brings controlled heating(More)
The resource management in distributed real-time systems becomes increasingly unpredictable with the proliferation of data-driven applications. Therefore, it is inefficient to allocate the resources statically to handle a set of highly dynamic tasks whose resource requirements (e.g., execution time) are unknown a prior. In this paper, we build a distributed(More)
Established in 1995, the Interstate Technology & Regulatory Council (ITRC) is a state-led, national coalition of personnel from the environmental regulatory agencies of some 40 states and the District of Columbia; three federal agencies; tribes; and public and industry stakeholders. The organization is devoted to reducing barriers to, and speeding(More)
Purpose and Scope This document has been developed to clarify and document the science requirements of the Pupil‐mapping Exoplanetary Coronagraphic Observer (PECO) mission. The PECO science team has been involved in its creation, and this document represents their consensus. This document has been written to guide the technical development of the PECO(More)
Since the first microkernel appeared, improving modularity and flexibility of operating systems, there has been support for application specific operating systems (ASOS). This term is often used to refer to the ability for cus-tomization and reconfiguration to meet the requirements of specific applications or application domains. The general idea is to(More)
