Module 30 year life: What does it mean and is it predictable-achievable? (open access)

Module 30 year life: What does it mean and is it predictable-achievable?

The authors define what they mean by a 30-year module life and the testing protocol that they believe is involved in achieving such a prediction. However, they do not believe that a universal test (or series of tests) will allow for such a prediction to be made. They can test for a lot of things, but they believe it is impossible to provide a 30-year certification for any PV module submitted for test. They explain their belief in this paper.

Oral History Interview with Frank Muoio, April 11, 2000 (open access)

Oral History Interview with Frank Muoio, April 11, 2000

The National Museum of the Pacific War presents an interview with Frank Muoio. Muoio joined the Navy in early 1942 and went aboard the USS Thomas Jefferson (APA-30) after training in Rhode Island. His first trip was to Brisbane delivering materiel. From there, he went to the invasions of North Africa, Sicily and Italy. Muoio shares several anecdotes about his experiences aboard the Thomas Jefferson. He went ashore during the invasion of Salerno. He was also involved in the Normandy invasion as well as Okinawa.

Relative stability of silicon self-interstitial defects (open access)

Relative stability of silicon self-interstitial defects

{l_brace}311{r_brace} defects and dislocation loops are formed after ion-implantation and annealing of a silicon wafer. Recent Transmission Electron Microscopy studies by Li and Jones have shown that sub-threshold dislocation loops nucleate from {l_brace}311{r_brace} defects. In our study, the conjugate gradient method with the Stillinger Weber potential is used to relax different configurations such as {l_brace}311{r_brace} defects with a maximum of five chains and perfect dislocation loops. From the formation energies thus obtained we find that there is an optimal width for each length of the {l_brace}311{r_brace} defects. Moreover the relative stability of {l_brace}311{r_brace}s and loops is studied as a function of defect size. We observe that at very small sizes the perfect loops are more stable than the {l_brace}311{r_brace}s. This may provide an explanation for the experimental observation by Robertson et al that, in an annealing study of end of range damage of amorphized samples, 45% of the loops had nucleated in the first 10 minutes of anneal. We propose that homogeneous nucleation, as against unfaulting of the {l_brace}311{r_brace}s, could be the source of these loops.

Sandia and the Waste Isolation Pilot Plant, 1974--1999 (open access)

Sandia and the Waste Isolation Pilot Plant, 1974--1999

Engineers have learned to design and build big projects, which certainly describes the WIPP project, but also includes defense projects, highway networks, space exploration, the Internet, etc., through what has been called a messily complex embracing of contradictions. When something massive and complicated has to be built these days, it leads to a protracted political process in which every special interest makes a stand, lobbyists exert what influence they can, lawmakers bicker, contractors change things, Congress struggles with costs, environmentalists hold things up--and this is good. It may seem amazing that anything gets done, but when it does, everyone has had their say. It's an intensely democratic, even if expensive and time-consuming, process. The corporate historian of Sandia National Laboratories presents a unique background of the WIPP project and Sandia's part in it.

Seamless multiresolution isosurfaces using wavelets (open access)

Seamless multiresolution isosurfaces using wavelets

Data sets that are being produced by today's simulations, such as the ones generated by DOE's ASCI program, are too large for real-time exploration and visualization. Therefore, new methods of visualizing these data sets need to be investigated. The authors present a method that combines isosurface representations of different resolutions into a seamless solution, virtually free of cracks and overlaps. The solution combines existing isosurface generation algorithms and wavelet theory to produce a real-time solution to multiple-resolution isosurfaces.

Social Security Reform: Bills in the 106th Congress (open access)

Social Security Reform: Bills in the 106th Congress

The Social Security system is projected to have long-range funding problems. Although the system’s income currently exceeds its expenditures, its trust funds are projected to be depleted in 2037. Concern about the problem and a belief that the remedy lies partly in economic growth that could be bolstered by changes to the system have led to introduction of a number of bills incorporating varying degrees of reform. This report describes the funding problem in some detail, summarizes many of the reform bills introduced in the 106th Congress, and provides a list of other related CRS reports.

Tanks Focus Area site needs assessment FY 2000

This report documents the process used by the Tanks Focus Area (TFA) to analyze and develop responses to technology needs submitted by five major U.S. Department of Energy (DOE) sites with radioactive tank waste problems, and the initial results of the analysis. The sites are the Hanford Site, Idaho National Engineering and Environmental Laboratory (INEEL), Oak Ridge Reservation (ORR), Savannah River Site (SRS), and West Valley Demonstration Project (WVDP). During the past year, the TFA established a link with DOE's Fernald site to exchange, on a continuing basis, mutually beneficial technical information and assistance.

TRANSVERSE POLARIZATION DISTRIBUTION AND FRAGMENTATION FUNCTIONS (open access)

TRANSVERSE POLARIZATION DISTRIBUTION AND FRAGMENTATION FUNCTIONS

The authors discuss transverse polarization distribution and fragmentation functions, in particular, T-odd functions with transverse momentum dependence, which might be relevant for the description of single transverse spin asymmetries. The role of intrinsic transverse momentum in the expansion in inverse powers of the hard scale is elaborated upon. The sin {phi} single spin asymmetry in the process e {rvec p} {r_arrow} e{prime} {pi}{sup +} X as recently reported by the HERMES Collaboration is investigated, in particular, by using the bag model.

Twenty years of service at NBNM - Analysis of Spectrolab module (open access)

Twenty years of service at NBNM - Analysis of Spectrolab module

This study of adhesional strength and surface analysis of encapsulant and silicon cell samples from a Natural Bridges National Monument (NBNM) Spectrolab module is an attempt to understand from its success. The module was fabricated using polyvinyl butyral (PVB) as an encapsulant. The average adhesional shear strength of the encapsulant at the cell/encapsulant interface in this module was 4.51 MPa or {approximately} 18% lower than that in currently manufactured modules. Typical encapsulant surface composition was as follows: C 75.0 at.% O 23.2 at.%, and Si 1.6 at.%, with Ag {approximately}0.2 at.% and Pb {approximately} 0.5 at.% with some tin respectively over the grid lines and solder bond. Representative silicon cell surface composition was: K 1.4 at.%, C 20.8 at.%, Sn 0.94 at.%, O 15.1 at.%, Na 2.7 at.% and Si 59.0 at.%. The presence of tin detected on the silicon cell surface may be attributed to corrosion of solder bond. The module differs from typical contemporary modules in the use of PVB, metallic mesh type interconnection, and silicon oxide AR coating.
