Clean Water Act and Total Maximum Daily Loads (TMDLs) of Pollutants
Section 303(d) of the Clean Water Act requires states to identify waters that are impaired by pollution, even after application of pollution controls. For those waters, states must establish a total maximum daily load (TMDL) of pollutants to ensure that water quality standards can be attained. Implementation was dormant until recently, when states and EPA were prodded by numerous lawsuits.

Cleanliness Validation of NIF Small Optics
The National Ignition Facility will be the highest energy laser in the world when completed. Many small optics ({le} 14 inches in diameter) have stringent transport efficiency and some have very high laser fluence requirements. For optics to sustain high spectral efficiencies and survive high fluences for a 30-year operation, these optics have cleanliness requirements to assure optimal laser system performance. These optical components have insufficient surface areas to validate the particulate and organic contamination requirements by methods used for mechanical parts. Also, the common validation techniques require some sort of surface contact which is not compatible with handling of laser optics. This presentation describes alternate cleanliness validation methods developed for the NIF small optical components. An organic validation procedure was devised based on the spectral transmission sensitivity to contamination layers on coated and uncoated fused silica windows. Optics were scanned in the near infrared before and after an application of a specific amount of organic contamination onto the surface. Changes in transmission correlated to organic contamination levels and used to determine non-volatile organic contamination optics. A validation method for particulate contamination was demonstrated on a large window, showing that acceptable cleanliness levels could be achieved after a wet-wipe and …

Combustion in Homogeneous Charge Compression Ignition Engines: Experiments and Detailed Chemical Kinetic Simulations
Homogeneous charge compression ignition (HCCI) engines are being considered as an alternative to diesel engines. The HCCI concept involves premixing fuel and air prior to induction into the cylinder (as is done in current spark-ignition engine) then igniting the fuel-air mixture through the compression process (as is done in current diesel engines). The combustion occurring in an HCCI engine is fundamentally different from a spark-ignition or Diesel engine in that the heat release occurs as a global autoignition process, as opposed to the turbulent flame propagation or mixing controlled combustion used in current engines. The advantage of this global autoignition is that the temperatures within the cylinder are uniformly low, yielding very low emissions of oxides of nitrogen (NO{sub x}, the chief precursors to photochemical smog). The inherent features of HCCI combustion allows for design of engines with efficiency comparable to, or potentially higher than, diesel engines. While HCCI engines have great potential, several technical barriers exist which currently prevent widespread commercialization of this technology. The most significant challenge is that the combustion timing cannot be controlled by typical in-cylinder means. Means of controlling combustion have been demonstrated, but a robust control methodology that is applicable to the entire range …

Computational Biology: A Strategic Initiative LDRD
The goal of this Strategic Initiative LDRD project was to establish at LLNL a new core capability in computational biology, combining laboratory strengths in high performance computing, molecular biology, and computational chemistry and physics. As described in this report, this project has been very successful in achieving this goal. This success is demonstrated by the large number of referred publications, invited talks, and follow-on research grants that have resulted from this project. Additionally, this project has helped build connections to internal and external collaborators and funding agencies that will be critical to the long-term vitality of LLNL programs in computational biology. Most importantly, this project has helped establish on-going research groups in the Biology and Biotechnology Research Program, the Physics and Applied Technology Directorate, and the Computation Directorate. These groups include three laboratory staff members originally hired as post-doctoral researchers for this strategic initiative.

Computer-aided analysis of eddy current rotating probe data.
Eddy current (EC) estimate of flaw size obtained from inservice inspection is often the primary means of assessing the structural integrity of steam generator tubes. Reliable prediction of failure pressure and leak rate in tubes with complex cracking requires more detailed information about the geometry and extent of degradation than is generally available from conventional bobbin coil examinations. High-resolution inspections with EC rotating probes are thus carried out on selected regions of tubing to provide the more extensive nondestructive evaluation (NDE) information that is needed to better assess flaw size and distribution. Interpretation of signals from complex cracking that are often distorted by coherent and incoherent noise can be a challenging NDE task. Studies at Argonne National Laboratory have demonstrated that computer-aided data analysis can be used for more accurate and efficient processing of the large amounts of data collected by such probes. The basic structure of a rule-based multiparameter data analysis algorithm is described in this paper. Multiple-frequency inspection data from a standard rotating pancake coil were used for the analyses. The codes were implemented as MATLAB scripts and provide, as the final outcome, profiles of flaw depth in a section of tube. Graphical user interface tools were devised …

Contract Management: Roles and Responsibilities of the Federal Supply Service and Federal Technology Service
Correspondence issued by the General Accounting Office with an abstract that begins "GAO reviewed the roles and responsibilities of the General Services Administration's (GSA) Federal Supply Service (FSS) and Federal Technology Service (FTS). Specifically, (1) the possible impact of the current FSS/FTS overlap on the prices paid for and quality of the services provided customer agencies by FSS and FTS, (2) whether the use of streamlined practices and procedures could result in savings and increases in service effectiveness, and (3) whether the statement of work that governs the study of the FSS and FTS that GSA has under contract will likely result in the kind of information needed to assess whether the current organization needs to be restructured."

Contract Management: Taking a Strategic Approach to Improving Service Acquisitions
Testimony issued by the General Accounting Office with an abstract that begins "The Service Acquisition Reform Act of 2002 seeks to strengthen the acquisition workforce by moving toward a performance-based contracting environment and improving service acquisitions management. During the past decade, federal agencies have substantially increased their purchases of services, particularly for information technology and professional, administrative, and management support. In fiscal year 2001 alone, the federal government acquired $109 billion in services. This money, however, is not always well-spent. GAO continues to find that defense and civilian acquisitions are poorly planned, not adequately completed, and poorly managed. Some leading companies have changed their approach to acquiring services after finding themselves spending a lot of money on services without knowing how much was being spent and where these dollars were going. GAO found that these companies were able to turn this situation around by adopting a more strategic perspective to service spending. Each company focused more on what was good for the company as a whole rather than just individual business units, and each began making decisions using enhanced knowledge about service spending. The companies analyzed their spending services to answer basic questions about how much was being spent and …
