From Wikipedia: "Exascale computing refers to computing systems capable of at least one exaFLOPS. Such capacity represents a thousandfold increase over the first petascale computer that came into operation in 2008. One exaflop is a thousand petaflops or a quintillion 1018 floating point operations per second. At a supercomputing conference in 2009 Computerworld projected exascale implementation by 2018. In January 2012 Intel purchased the InfiniBand product line from QLogic for US $125 million in order to fulfill its promise of developing exascale technology by 2018. The initiative has been endorsed by two US agencies: the Department of Energy and the National Nuclear Security Administration. The technology would be useful in various computation-intensive research areas including basic research engineering earth science biology materials science energy issues and national security. The United States has put aside $126 million for exascale computing beginning in 2012. Three projects aiming at developing technologies and software for exascale computing have been started in 2011 within the European Union. The CRESTA project Collaborative Research into Exascale Systemware Tools and Applications the DEEP project Dynamical ExaScale Entry Platform and the project Mont-Blanc. The Indian Government has committed USD 2 Billion to ISRO and Indian Institute of Science IISc Bangalore to develop a supercomputer with a performance of 132.8 exaflops by 2017. ISRO has already booked key equipment to develop the first Indian exaflop supercomputer. Most of the sub-systems will be developed in India." United States, Department of Energy paperback

Significant Finding Investigations were addressed in DOE/IG-0535 Audit Report Management of the Stockpile Surveillance Program's Significant Finding Investigations December 2001. The Directors of the three nuclear weapons laboratories annually assess and report the condition of the weapon systems for which their laboratories are responsible. A critical event in this process is the identification of a defect or malfunction during surveillance testing. This is especially important when dealing with an aging weapons stockpile. Departmental procedures require preliminary tests or evaluations to establish whether a Significant Finding Investigation SFI should be initiated. Such investigations are then conducted to determine the identified problem's cause and impact and to recommend corrective actions. Weapons surveillance began in the US in the mid-1960s when weapons testing was done through underground explosions of nuclear devices. Such testing continued until the early 1990s. If tests on a weapon system show an anomaly - a possible problem with a part that could jeopardize the system operation - with a system evaluation engineer SEE is notified. It is the SEE's job to determine if the anomaly could affect the surety safe use or reliability of the weapon. If the SEE makes that determination he/she opens a "significant finding investigation SFI. The responsibility of the investigation team is to determine the cause and impact of the defect and to make recommendations for corrective actions.

CD. As new. This item is still in its original plastic wrap. The rear of the sleeve lists the contents: Overview Defense Applications and Modeling; Simulation and Computer Science Integrated Computing Systems University Partnerships Special Projects ASCI's future ASCI's Multidisciplinary Applications. Among the subsections are: Visualization Technilogies at the Los Alamos National Laboratory Visualization Technologies at Sandia National Laboratories ASCI White at Lawrence Livermore National Laboratory Science at the Level 1 Alliances and Technology Prospectus. The U.S. Department of Energy DOE established the Accelerated Strategic Computing Initiative ASCI in 1996. The goal of ASCI is to simulate the results of new weapons designs as well as the effects of aging on existing and new designs all in the absence of underground nuclear tests. The ASCI is an applications-driven effort with a goal to develop reliable computational models of the processes involved in the design manufacture and degradation of nuclear weapons. Based on discussions with scientists and engineers with expertise in weapons design manufacturing and in computational physics a goal of simulating full-system three-dimensional nuclear burn and safety simulation processes by the year 2004 was established. A number of applications-based milestones were identified to mark the progress from current simulation capabilities to full-system simulation capabilities. Codes development to simulate casting material aging safety forging welding of microstructures and so on. unknown

Washington DC: United States Department of Energy Energy Information Administration 1994. Presumed first edition/first printing. Wraps. Very good. No dust jacket. Covers have slight wear and soiling. 2 volume set. xiii 91 v159 p. Includes illustrations. Glossary. From an EPA website: "Reformulated gasoline RFG is gasoline blended to burn more clearly than conventional gasoline and to reduce smog-forming and toxic pollutants in the air we breathe. The RFG program was mandated by Congress in the 1990 Clean Air Act amendments. The first phase of the RFG program began in 1995 and the second current phase began in 2000. RFG is required in cities with high smog levels and is optional elsewhere. RFG is currently used in 17 states and the District of Columbia. About 30 percent of gasoline sold in the U.S. is reformulated. The air quality benefits RFG has achieved represent a significant part of the country's smog reduction strategy. The RFG program combined with other industrial and transportation controls aimed at smog reduction is contributing to the long-term downward trend in U.S. smog levels. About 75 million people breathe cleaner air because of RFG." United States Department of Energy, Energy Information Administration paperback

Various paginations approximately 125 pages. References. From Wikipedia: "The Stratospheric Observatory for Infrared Astronomy SOFIA is a joint project of NASA and the German Aerospace Center DLR to construct and maintain an airborne observatory. NASA awarded the contract for the development of the aircraft operation of the observatory and management of the American part of the project to the Universities Space Research Association USRA in 1996. The DSI Deutsches SOFIA Institut manages the German parts of the project which are primarily science and telescope related. SOFIA's telescope saw first light on May 26 2010. SOFIA is the successor to the Kuiper Airborne Observatory.SOFIA is based on a Boeing 747SP wide-body aircraft that has been modified to include a large door in the aft fuselage that can be opened in flight to allow a 2.5 meter diameter reflecting telescope access to the sky. This telescope is designed for infrared astronomy observations in the stratosphere at altitudes of about 41 000 feet about 12 km. SOFIA's flight capability allows it to rise above almost all of the water vapor in the Earth's atmosphere which blocks some infrared wavelengths from reaching the ground. At the aircraft's cruising altitude 85% of the full infrared range will be available. The aircraft can also travel to almost any point on the Earth's surface allowing observation from the northern and southern hemispheres. Once ready for use the expectation is for observing flights to be flown 3 or 4 nights a week for the next 20 years. SOFIA is now based at NASA's Dryden Aircraft Operations Facility at LA/Palmdale Regional Airport California while staff at NASA Ames Research Center in Mountain View California operate the SOFIA Science Center where astronomical observation missions are planned for the flying observatory. The NASA logo reflected in SOFIAs 2.5-meter primary mirror. SOFIA uses a 2.5-meter reflector telescope which has an oversized 2.7 meter diameter primary mirror as is common with most large infrared telescopes. The optical system uses a Cassegrain reflector design with a parabolic primary mirror and a remotely configurable hyperbolic secondary. In order to fit the telescope into the fuselage the primary is shaped to an f-number as low as 1.3 while the resulting optical layout has an f-number of 19.7. A flat tertiary dichroic mirror is used to deflect the infrared part of the beam to the Nasmyth focus where it can be analyzed. An optical mirror located behind the tertiary mirror is used for a camera guidance system. The telescope looks out of a large door in the side of the fuselage near the airplane's tail and will initially carry nine instruments for infrared astronomy at wavelengths from 1 655 micrometres and high-speed optical astronomy at wavelengths from 0.3 1.1 micrometres. The main instruments are the FLITECAM a near infrared camera covering 1 5 micrometres; FORCAST covering the mid-infrared range of 5 40 micrometres and HAWC which spans the far infrared in the range 42 210 micrometres. The other four instruments include an optical photometer and infrared spectrometers with various spectral ranges. SOFIA s telescope is by far the largest ever to be placed in an aircraft. For each mission one interchangeable science instrument will be attached to the telescope. Two groups of general purpose instruments are available. In addition an investigator can also design and build a special purpose instrument. On April 17 2012 two upgrades to HAWC were selected by NASA to increase the field of view with new detector arrays and to add the capability of measuring the polarization of dust emission from celestial sources. The open cavity housing the telescope will be exposed to high-speed turbulent winds. In addition the vibrations and motions of the aircraft introduce observing difficulties. The telescope was designed to be very lightweight with a honeycomb shape milled into the back of the mirror and polymer composite material used for the telescope.
