Feedback as a means of decreasing residential energy consumption. Report PU/CES 34 (open access)

Feedback as a means of decreasing residential energy consumption. Report PU/CES 34

When residential units are analyzed in human factor terms, it is apparent that the consumption level feedback (typically a bill, calculated once a month, over all appliances) is inadequate to give the resident useful information about his energy consuming actions. The present study tested the hypothesis that providing immediate feedback to homeowners concerning their daily rate of electric usage would be effective in reducing electric consumption. In the studied homes, central air-conditioning is the largest single source of electric power consumption during the summer. Accordingly, it was possible to predict the household's expected electric consumption in terms of the average daily outdoor temperature. Predicted electric consumption was derived from a previous month's modeling period during which a regression line was fitted to predict consumption from average daily temperature, for each home. Feedback was expressed as a percentage of actual consumption over predicted consumption. Feedback was displayed to homeowners four times a week for approximately one month. The results confirmed the prediction. Before feedback began, the feedback and control groups were consuming electricity at approximately equal rates. During the feedback period, the feedback group used 10.5 percent less electricity. The effectiveness of the feedback procedure was explained in terms of its …

Burrs produced by grinding (open access)

Burrs produced by grinding

An investigation was conducted to determine the influence of variables in controlling the size and repeatability of grinding burrs to minimize burr-removal costs and improve the quality and reliability of parts for small precision mechanisms. Each of the three types of burrs produced by surface-grinding a rectangular block responds differently to changes in cutting conditions. Reducing the downfeed rate generally produces shorter burrs. Although the size of the abrasive grain affected the thickness of one of the burrs, thickness was relatively unaffected by the variables studied. The thickest burrs occurred on low-carbon steel.

Creep of circular plates using a state-variable approach (open access)

Creep of circular plates using a state-variable approach

The technical theory of bending of circular plates under axisymmetric lateral loads is formulated in terms of Hart's state-variable equations. Then the method is applied to plates with simply supported and clamped edges through a standard algorithm. All the analytical results obtained compare qualitatively with those reported in the literature. The influence of the state variable called ''hardness'' is clearly demonstrated. Thus the analysis and the results provide a basis for acceptance of the model applied to structural components in a multiaxial state of stress.

Friction and wear studies for bonded thin-film lubricants (open access)

Friction and wear studies for bonded thin-film lubricants

Bonded dry-film lubricants were evaluated to select a suitable lubricant for use in electromechanical devices which must be highly reliable after extended periods of storage and exposure to extreme atmospheric conditions. Mechanism tolerances and clearances require that the bonded lubricants be applied in thin films from 0.0002 to 0.0005 inch in thickness and that they exhibit a low friction coefficient both at the light loads of ambient environments and the loads of high-g environments. A tribometer, needed to obtain friction data by several techniques from dry-film-lubricant samples at light and moderate loads, was developed, since a suitable instrument was not commercially available. Light-load friction and wear characteristics were determined for ten commercially available, bonded dry-film lubricants. Of the six lubricants originally evaluated, Electrofilm 4396 was judged to be the best of the group. A later preliminary study of four other lubricants revealed that Electrofilm 77S may be better than 4396 for use in the small precision electromechanical devices. After tests on the original six lubricants found 4396 to be superior, a factorial design experiment used it to find the interaction between such friction-influencing variables as substrate finish and hardness, mating-part finish and hardness, and film polishing.

Evaluation of environmental data relating to selected nuclear power plant sites: the Three Mile Island Nuclear Station Site

Environmental monitoring data for the years 1973 and 1974 pertaining to the Three Mile Island Nuclear Station Unit 1, which began operation in early 1974, were analyzed by the most practical qualitative and quantitative methods. Terrestrial biotic resources were considered for this plant. The effects of the operation of Unit 1 on the local terrestrial organisms were found to be undetectable. Although the plant has not operated long enough to reveal long-term deleterious effects, the present indications do not lead to a concerned prediction that any are developing. The data acquired, method of analysis, and results obtained are presented in detail along with recommendations for improving monitoring techniques.

Feasibility study for the computerized automation of the Annapolis Field Office of EPA region III

This report describes a feasibility study for computerized automation of the Annapolis Field Office (AFO) of EPA's Region III. The AFO laboratory provides analytical support for a number of EPA divisions; its primary function at present is analysis of water samples from rivers, estuaries, and the ocean in the Chesapeake Bay area. Automation of the AFO laboratory is found to be not only feasible but also highly desirable. An automation system is proposed which will give major improvements in analytical capacity, quality control, sample management, and reporting capabilities. This system is similar to the LLL-developed automation systems already installed at other EPA laboratories, with modifications specific to the needs of the AFO laboratory and the addition of sample file control. It is estimated that the initial cost of the system, nearly $300,000, would be recouped in about three years by virtue of the increased capacity and efficiency of operation.

Rework of multilayer printed wiring board assemblies (open access)

Rework of multilayer printed wiring board assemblies

Processes of reworking printed wiring assemblies (PWA) built with multilayer printed wiring boards (MLPWB) were investigated. Because of the MLPWBs added thickness and increased heat absorption potential, assemblies built with these boards are suspected of being more susceptible to damage during component removal than assemblies built with single-layer double-sided boards. There also have been questions raised about the effect that rework has on the internal connections of the MLPWBs. A review and limited evaluation of all known rework methods resulted in selecting ''solder wick'' and ''vacuum extraction'' as the two main rework methods for use in the evaluations. The Appendix defines and describes these rework techniques. Two different groups of units, intended to be representative of a wide range of proposed and presently used MLPWB-component configurations, were fabricated and then reworked by variations of these two techniques. Approximately 16,000 internal connections of MLPWBs were subjected to rework. No internal connections became open or degraded. In addition, 80 PTHs with internal connections were subjected to 10 cycles of rework to examine the effect of rework on MLPWB internal connections. Continuity of the internal connections was measured before and after all rework. Even though the rework did cause extensive external damage to …

ERDA artificial heart program workshop. Final report, September 1, 1975--August 31, 1976

The major conclusions of the ERDA Artificial Heart Program Workshop are that the concept of a biologically compatible mechanical device which can totally replace the heart is sound, that such a device is needed as an alternative to cardiac transplantation and that its development is a realistic goal. The major recommendation of the committee is that an ERDA program with primary orientation toward development of a total heart replacement should continue, with assured funding about 50 percent higher than at present, for a minimum of 3 additional years at which time another major review should take place. To achieve better management of the program it is recommended that the present contract effort be reorganized under one prime contractor with responsibility for development and demonstration of the ERDA artificial heart system. The formation of a joint artificial heart advisory committee to improve coordination between ERDA and NHLI is also recommended. The committee suggests future policies and directions which it believes will lead to more effective use of funds available for specific aspects of the program. These include the nuclear heart source, engine, blood pump, biomaterials and overall system reliability. Possible future goals for the program are also proposed.

Movements and behavior of largemouth bass (Micropterus salmoides) and steelhead (Salmo gairdneri) determined by radio telemetry

The organization of this thesis reflects the development of underwater radio tracking methodology for monitoring movements of freshwater fish. Equipment and techniques developed during this research are described in Part I and represent a cooperative effort between the author and the University of Minnesota's Cedar Creek engineering staff. In 1970, the equipment and techniques were tested and perfected during a study of largemouth bass movements in Mary Lake. The bass project provided an ideal situation to test the system. Since Mary Lake was small and the bass exhibited localized movements, the fish could be found easily; consequently, the performance of the system could be continually analyzed and problems could be quickly solved. The home range movements of the bass are described in Part II. After establishing the reliability and usefulness of the system, a much more difficult project was attempted. In 1971, a program was initiated to study the movements and behavior of steelhead in western Lake Superior. Results of this project (1971 to 1974) are presented in Part III.

Generalization of International Centrifugal Zone Growth of Metal-Ceramic Composites. Progress Report, December 1, 1975--November 30, 1976

Research conducted to develop a realistic model of Internal Centrifugal Zone Growth (ICZG) and to utilize the predictive capacities of this model to improve and extend present ICZG systems is reported. One-dimensional models for (hypothetical) infinitely large samples heated by long RF induction coils were previously developed and an S-curve instability phenomenon associated with spontaneous coupling of the RF field to materials whose electrical conductivity increases significantly with temperature was predicted. This model was extended to two dimensions to account for finite samples and coils. During the reporting period one-dimensional modeling was used in predicting additional instabilities (S shaped with a cusp) on melting which are ''piggy-back'' with the S-curve instabilities at lower temperatures. The low temperature S instability has been demonstrated for silicon; whereas, in cooperation with Oak Ridge, the predictive capacities of the modeling have been used to engineer around instabilities in the CrO/sub 3/-Mo systems and to extend ICZG to a number of other materials.

Calculated pressure-broadened linewidths of H/sub 2/S

Self-broadened and foreign-gas (N/sub 2/ and O/sub 2/) broadened linewidths of H/sub 2/S at 300/sup 0/K for a wide range of quantum numbers J and K/sub a/, for both type A and type B bands, have been calculated using the Anderson-Tsao-Curnutte theory of line broadening. In the case of H/sub 2/S-H/sub 2/S collisions, dipole-dipole, dipole-quadrupole, quadrupole-dipole, and quadrupole-quadrupole interactions have been included. For H/sub 2/S-N/sub 2/ and H/sub 2/S-O/sub 2/ collisions, dipole-quadrupole and quadrupole-quadrupole interactions were taken into account. Computed values for self-broadened linewidths are in good agreement with the experimental results of Helminger and De Lucia. Air-broadened linewidths of H/sub 2/S at 200/sup 0/K have also been calculated, so that the temperature dependence can be established.
