After-hours Power Status of Office Equipment and Inventory of Miscellaneous Plug-load Equipment
This research was conducted in support of two branches of the EPA ENERGY STAR program, whose overall goal is to reduce, through voluntary market-based means, the amount of carbon dioxide emitted in the U.S. The primary objective was to collect data for the ENERGY STAR Office Equipment program on the after-hours power state of computers, monitors, printers, copiers, scanners, fax machines, and multi-function devices. We also collected data for the ENERGY STAR Commercial Buildings branch on the types and amounts of ''miscellaneous'' plug-load equipment, a significant and growing end use that is not usually accounted for by building energy managers. This data set is the first of its kind that we know of, and is an important first step in characterizing miscellaneous plug loads in commercial buildings. The main purpose of this study is to supplement and update previous data we collected on the extent to which electronic office equipment is turned off or automatically enters a low power state when not in active use. In addition, it provides data on numbers and types of office equipment, and helps identify trends in office equipment usage patterns. These data improve our estimates of typical unit energy consumption and savings for each …

Campaign Finance: Constitutional and Legal Issues of Soft Money
Prior to enactment of the Bipartisan Campaign Reform Act of 2002 (BCRA), P.L. 107-155, the term “soft money” generally referred to unregulated funds, perceived as resulting from loopholes in the Federal Election Campaign Act (FECA), 2 U.S.C. §§ 431 et seq. Generally, the intent of BCRA, (effective Nov. 6, 2002), which amends FECA, is to restrict the raising and spending of soft money. This Issue Brief discusses constitutional and legal issues surrounding two major types of soft money that BCRA regulates: political party soft money and soft money used for issue advocacy communications. Corporate and labor union soft money, which FECA exempts from regulation and is not addressed by BCRA, is also discussed.

Concurrent Multiscale Simulation at Finite Temperature: Coarse-Grained Molecular Dynamics
With the advent of nanotechnology, predictive simulations of nanoscale systems have become in great demand. In some cases nanoscale systems can be simulated directly at the level of atoms. The atomistic techniques used range from models based on a quantum mechanical treatment of the electronic bonds to those based on more empirical descriptions of the interatomic forces. In many cases, however, even nanoscale systems are too big for a purely atomistic approach, typically because the nanoscale device is coupled to its surroundings, and it is necessary to simulate the entire system comprising billions of atoms. A well-known example is the growth of nanoscale epitaxial quantum dots in which the size, shape and location of the dot is affected by the elastic strain developed in a large volume of the substrate as well as the local atomic bonding. The natural solution is to model the surroundings with a more coarse-grained description, suitable for the intrinsically longer length scale. The challenge then is to develop the computational methodology suitable for this kind of concurrent multiscale modeling, one in which the simulated length scale can be changed smoothly and seamlessly from one region of the simulation to another while maintaining the fidelity of …

Dual-Use Biological Equipment: Difficulties in Domestic Regulation
A question in the current debate over chemical and biological terrorism is: how well do current United States policies limit opportunities to terrorist groups for acquisition of such weapons? The domestic purchase and use of “dual-use” biological equipment, such as fermenters, centrifuges, and other equipment, is one area suggested as potentially providing opportunities for terrorist, biological weapons development. Dual-use equipment has both legitimate civilian and military use. Regulating international sale of dual-use equipment is used as a nonproliferation policy tool. Similar regulation of domestic sales has not been employed. This report will discuss the difficulties of applying domestic controls on dual-use biological equipment and the potential advantages and disadvantages of doing so.

Error Estimation for Reduced Order Models of Dynamical Systems
The use of reduced order models to describe a dynamical system is pervasive in science and engineering. Often these models are used without an estimate of their error or range of validity. In this paper we consider dynamical systems and reduced models built using proper orthogonal decomposition. We show how to compute estimates and bounds for these errors, by a combination of small sample statistical condition estimation and error estimation using the adjoint method. Most importantly, the proposed approach allows the assessment of regions of validity for reduced models, i.e., ranges of perturbations in the original system over which the reduced model is still appropriate. Numerical examples validate our approach: the error norm estimates approximate well the forward error while the derived bounds are within an order of magnitude.

Final report summary of LDRD 02-LW-022''Quantum Vibrations in Molecules: A New Frontier in Computational Chemistry''
With the trend towards needing information about chemistry at conditions significantly different from 298K and 1 atm., methods need to be developed to generate and interpret this data. This demand for information about chemistry at extreme conditions comes from many fields. The study of atmospheric chemistry requires knowledge of unusual species that are formed when molecules are exposed to ultraviolet radiation. Studying of energetic materials requires knowledge of the thermochemical and structural properties of a myriad of chemical species under a wide range of temperatures. Basic scientific understanding of the very nature of a chemical bond requires detailed information. Studying these problems computationally requires multiple capabilities. The methodology used must provide both high accuracy and computational efficiency. Studying extreme chemistry also suffers from all the challenges of studying chemistry under non-extreme conditions. Therefore, either a new method must be developed or an old method must be applied in an innovative way. The method we have chosen to use is path integral Monte Carlo (PIMC) for the nuclear degrees of freedom and ab initio electronic structure methods for the electronic degrees of freedom. PIMC and ab initio electronic structure are methods of treating the quantum nature of particles. These methods have …

A Hydrologic-geophysical Method for Characterizing Flow and Transport Processes Within The Vadose Zone
The primary purpose of this project was to employ two geophysical imaging techniques, electrical resistivity tomography and cross-borehole ground penetrating radar, to image a controlled infiltration of a saline tracer under unsaturated flow conditions. The geophysical techniques have been correlated to other more traditional hydrologic measurements including neutron moisture measurements and induction conductivity logs. Images that resulted during two successive infiltrations indicate the development of what appear to be preferential pathways through the finer grained materials, although the results could also be produced by cationic capture of free ions in clays. In addition the site as well as the developing solute plume exhibits electrical anisotropy which is likely related to flow properties. However the geologic significance of this phenomenon is still under investigation.
