This report is concerned with ergodic theorems for Abel means of nonlinear contraction mappings and nonlinear contraction semigroups in a Hilbert space.

Two ergodic theorems are presented for means of nonlinear contraction semigroups in a Hilbert space. These means are generated by a class of averaging kernels which includes the usual Abel and Cesaro-(C,cap alpha) kernels.

Let E be a reflexive Banach space with a uniformly Gateaux differentiable norm, D a closed convex subset of E, and C a nonexpansive retract of D.

Report discusses the development of the existing ALICE Image Processing System into a computer-aided digitization, encoding, analysis and display system for mapped information pertaining to the environment and its elements.

Volume 2 presents information which is directly related to the actual computer code arid operational characteristics (keys and subroutines) of the software. The authors expect that Volume I will be of more interest to developers of software than to users of the software. However, developers of software should be aware that the code developed for the ALICE System operates in an environment where much of the peripheral hardware to the PDP-10 is ANL/AMD built. For this reason, portions of the code may have to be modified for implementation on other computer system configurations.

Evaluation of melt-slagging techniques as a decontamination and consolidation step for metals contaminated with oxides of plutonium and americium.

Creep data from the literature search is reinterpreted by SGI, resulting in a better understanding of the temperature and stress state dependence of the octahedral creep rate and the octahedral shear strength. The concept of a transition strength between the elastic and the plastic states is in agreement with the data. The elastic and rheological properties of salt are described, and a set of constitutive equations is presented. The dependence of material properties on parameters such as temperature is considered. Findings on the permeability of salt are summarized, and the in-situ behavior of openings in bedded salt is described based on extensive engineering experience. A stress measuring system utilizing a finite element computer code is discussed. Geological factors affecting the stability of salt openings are considered, and the Stress Control Technique for designing stable openings in bedded salt formations is explained.

This volume contains brief appendixes of three types: (1) some topics, although their analyses were not directly requested in the contract work statement, are examined because they are central to determining the validity of the Energyplex concept (e.g., socioeconomic effects and anaerobic digestion of animal wastes to recovery energy). (2) Methane from Illinois coal beds is discussed as a potential energy resource; however detailed analysis has been prevented by the paucity of necessary geological data. (3) Those Energyplex elements whose brief examination revealed some barrier are noted. For example, recovering energy from the relatively small amount of municipal waste generated by Charleston and Mattoon shows no economic promise, and cement production in the southeast quadrant of Illinois appears to be limited by inadequate quantities of limestone of the proper quality.

Optical ionization effects in gases appear to be very sensitive indicators of nonuniformities caused by contamination, deformation, and other factors affecting a metal surface. These optical effects are influenced by surface electron emission, which is influenced in turn by the chemical, metallurgical, and mechanical condition of the metal surface. Based on these effects, a general technique for inspection of critical parts that is fast, inexpensive, nondestructive, and not limited by size or geometry is presented. Ionization effects that reveal nonuniformities and were recorded with standard photographic equipment are shown.

This primer was developed as part of the study conducted by the Laboratory for Nuclear Science (LNS) on the feasibility of networks for computer resource sharing. The primer is an instructinal guide for the LNS user who would like to access and use computers at other government sites on the ARPA network. The format is a series of scenarios of actual recorded on-line terminal sessions' showing the novice user how to access the foreign site, obtain help documentation, run a simple program, and transfer files to and from the foreign site. Access to the ARPA network in these scenarios is via Multics or the Massachusetts Institute of Technology Terminal Interface Processor. The foreign government sites accessed are the computing facilities at Argonne National Laboratory, Brookhaven National Laboratory, Lawrence Livermore Laboratory, and New York University Courant Institute. This technique of auditing actual terminal sessions as a teaching aid can be extended to include other computing facilities as well as other networks.

The technical and economic feasibility of retrofitting thermal power plants in Minnesota to accommodate both heat and power generation for district heating was examined and is discussed. Three communities were identified as viable sites for co-generation district heating. (LCL)

This report summarizes the results of an economic evaluation of the MIT process for the manufacture of ethanol from cellulosic residues. Conceptual process designs were developed for two cases, Case A which is based on the experimental data obtained to date, and Case B which hypothesizes the suppression of acid byproducts. Manufacturing costs, including profit, were estimated at $12.20/million Btu for Case A and $9.40/million Btu for Case B. These are equivalent to about $1.05 and $0.80/gal ethanol respectively. These economic estimates may be slightly on the low side since they do not consider feedstock storage nor working capital requirements. Nevertheless, the manufacturing costs for Case A appear to be comparable to those of the manufacture of ethanol from corn. The plant size used for this analysis was 1500 ton/day corn stover. This is considered to be a realistic size. The conceptual plants make about 27 million gal/yr ethanol in Case A and 41 million gal/yr in Case B. The MIT process appears to be one of the more promising programs being developed under contract for DOE. It is recommended that the process research be continued. Three areas of concern were identified which must be investigated before the process can …

A summary is presented of the experimental development and testing of a muon polarimeter, a device to be used in an experiment proposed for the PEP facility. The work consisted of two phases. Phase one was the cosmic ray studies, done at Brown University during the summer of 1978, using a small model of the actual polarimeter. A second series of tests, done on a much more sophisticated version of the polarimeter, was conducted at the Brookhaven AGS A2 test beam. A discussion of the polarimeter concept and a brief description of some of the hardware used in the experimental work are given. Results of the summer tests are discussed, and theoretical calculations of the quantities of interest in the Brookhaven tests are presented. (GHT)

The use of a biphase turbine system to recover waste heat from diesel engines was examined and found to have many favorable attributes. Among these were low rpm, high torque, low heat exchanger cost, and simplicity. Several candidate working fluid combinations were tested at temperatures of interest. The contact heat exchanger concept was substantiated by large scale experiment. The program includes subscale tests of key hardware components of a biphase turbine bottoming system. These are the two-phase nozzle, two-phase turbine, and direct contact heat exchanger. A comprehensive cost analysis was completed. A three-year program leading to a full-size system field demonstration has been planned. Progress in the first year of this program and the effort started on the second year program are reported.

A number of materials are commonly used as vacuum system walls. The desorption of gases from these materials may contribute significantly to the internal pressure of an unpumped device or to the gas load which a pump must handle in a dynamic system. This report describes the thermodesorption measurements made on a number of metals (molybdenum, nickel, Kovar alloy, copper, copper-2% beryllium alloy) and two insulators (molybdenum sealing glass ceramic and high alumina ceramic). All of the materials after typical cleaning and air exposure contain considerable gas. With a long 400/sup 0/ to 500/sup 0/ vacuum bake, however, all can be cleaned sufficiently so that they will not contribute appreciable gas to their surrounding when vacuum stored at room temperature for many years. Most materials display desorption kinetics which are first order (a single bond or trap energy must be overcome for desorption). It appears that the desorption of CO from Kovar is rate limited by carbon diffusion (D/sub 0/ approx. = .4 cm/sup 2//s and E/sub d/ approx. = 27,000 cal/mol). The desorption of hydrogen from glass ceramic also appears to be diffusion rate limited (D/sub 0/ approx. = 1 x 10/sup -3/ cm/sup 2//s and E/sub d/ approx. …

The design and public demonstration of the MIVAC Drying System for drying peanuts, corn, sorghum, corn, and rice and the drying times with various dryer systems are reported. (LCL)

The goal of this research was to convert the organics and sulfur in sulfite spent liquor (SSL) now classified as pollutants from sulfite pulp mills, into synthetic methane and protein by means of a combination chemical-biological process. Ozonization was used to break the high molecular weight lignosulfonate molecules present in SSL into lower weight fractions which could be metabolized by methane-producing bacteria and protein-producing yeast. Ozonization experiments showed that this treatment is effective in partially oxidizing and fragmenting lignosulfonates into fermentable substrates. This process is initiated at low ozone concentrations and proceeds rapidly until nearly 30% of the Chemical Oxygen Demand (COD) has been consumed. The conditions under which ozonization is conducted greatly affect the degree of oxidation and the molecular weight of the cleaved fragments. In spite of the appreciable oxidative cleavage of the lignosulfonate molecules, continuous-flow fermentation studies showed rather low yields of methane and yeast from ozonated SSL. Under optimum conditions, methane production averaged only 1.7 1/1 of SSL or approximately 3% of the total organics present. Protein production was somewhat more favorable with 6% of the organics being converted to yeast biomass. (6g/1). Neither fermentation fully used all of the oxygenated fragments produced by ozonization, and …

The Department of Energy contracted with Gibbs and Cox, M. Rosenblatt and Son and Lockheed Missile and Space Corporation to prepare conceptual designs, cost estimates and analyses for a 400 MWe OTEC Commercial Size platform. Each contractor was directed to investigate two predetermined hull configurations and to relate them to one operating site, selected by DOE. A total of 6 designs, covering sphere, spar, ship and semisubmersibles were studied by the three contractors. The results of their investigations were presented by DOE in Washington on May 8, 1978. The presentations showed that whereas a considerable data base has been built, no clear conclusions had emerged with respect to the direction that future design of the commercial platform should take. JJMA has been directed by Value Engineering on behalf of DOE to review the conceptual designs and the accompanying data base prepared by the three contractors. The intent of this review is to propose to DOE the answers to the following questions, based on the results of studies by the three contractors: (1) If DOE were to build a 400 MW OTEC plant, starting now, what should they build. (2) What are the reasons for the decisions. (3) What would it …

The Composite Bearingless Wind Turbine was developed at the United Technologies Research Center following many years of bearingless rotor research and development for helicopter applications. The current 8 kW contract was begun in October 1977 with delivery of the prototype scheduled for November 1979. The contract consists of two phases. Phase I encompasses the complete design of the system and supporting analytical and experimental studies. The Phase I final report has been completed, and this executive summary highlights the principal findings described in that report.

The results of a Bevalac experiment to measure the single electron attachment and stripping cross sections for relativistic (0.5 < ..beta.. < 0.95) C, Ne and Ar ions passing through thin solid targets ranging in atomic number from 4 (Be) to 79 (Au) are reported. Magnetic analysis was used to separate the single electron, N/sub 1/, and fully stripped, N/sub 0/, ion beams emerging from the targets. Separate counters measured the number of ions in each charge state. The ratios N/sub 1//N/sub 0/ for different target thicknesses were fit to a simple growth curve to yield electron attachment and stripping cross sections. The data are compared to relativistic extrapolations of available theories. Clear evidence for two separate attachment processes, radiative and non-radiative, is found. Data are compared to a recently improved formulation for the stripping cross sections.

The following appendices are included: (1) instruments, (2) electrical specifications, (3) protective coverings, (4) welding requirements, (5) engineering specifications, and (6) administrative. (MOW)

The task accomplished during the first six months of the cooperative agreement between the US Department of Energy and the Idaho Office of Energy is summarized, concentrating on geothermal resource data, regional and local development plans, energy and economic factors and institutional factors.

The potential hazard to man arising from the hypothetical release of radioactive spent fuel waste into various water systems has been evaluated. Radionuclide transport and human exposure were simulated for six water systems: a large Northwestern river, a small Northeastern river, a small Northwestern river, a large Central Region river, a lake with no outflow in an arid region, and an aquifer discharging directly into an ocean.
