An Automated Image Processing System for Concrete Evaluation

An Automated Image Processing System for Concrete Evaluation

Date: November 23, 1998
Creator: Baumgart, C.W.; Cave, S.P. & Linder, K.E.
Description: AlliedSignal Federal Manufacturing & Technologies (FM&T) was asked to perform a proof-of-concept study for the Missouri Highway and Transportation Department (MHTD), Research Division, in June 1997. The goal of this proof-of-concept study was to ascertain if automated scanning and imaging techniques might be applied effectively to the problem of concrete evaluation. In the current evaluation process, a concrete sample core is manually scanned under a microscope. Voids (or air spaces) within the concrete are then detected visually by a human operator by incrementing the sample under the cross-hairs of a microscope and by counting the number of "pixels" which fall within a void. Automation of the scanning and image analysis processes is desired to improve the speed of the scanning process, to improve evaluation consistency, and to reduce operator fatigue. An initial, proof-of-concept image analysis approach was successfully developed and demonstrated using acquired black and white imagery of concrete samples. In this paper, the automated scanning and image capture system currently under development will be described and the image processing approach developed for the proof-of-concept study will be demonstrated. A development update and plans for future enhancements are also presented.

Applying electrical utility least-cost approach to transportation planning

Applying electrical utility least-cost approach to transportation planning

Date: September 1, 1994
Creator: McCoy, G.A.; Growdon, K. & Lagerberg, B.
Description: Members of the energy and environmental communities believe that parallels exist between electrical utility least-cost planning and transportation planning. In particular, the Washington State Energy Strategy Committee believes that an integrated and comprehensive transportation planning process should be developed to fairly evaluate the costs of both demand-side and supply-side transportation options, establish competition between different travel modes, and select the mix of options designed to meet system goals at the lowest cost to society. Comparisons between travel modes are also required under the Intermodal Surface Transportation Efficiency Act (ISTEA). ISTEA calls for the development of procedures to compare demand management against infrastructure investment solutions and requires the consideration of efficiency, socioeconomic and environmental factors in the evaluation process. Several of the techniques and approaches used in energy least-cost planning and utility peak demand management can be incorporated into a least-cost transportation planning methodology. The concepts of avoided plants, expressing avoidable costs in levelized nominal dollars to compare projects with different on-line dates and service lives, the supply curve, and the resource stack can be directly adapted from the energy sector.

Final sitewide environmental assessment for continued development of Naval Petroleum Reserve No. 3 (NPR-3), Natrona County, Wyoming

Final sitewide environmental assessment for continued development of Naval Petroleum Reserve No. 3 (NPR-3), Natrona County, Wyoming

Date: July 1, 1995
Creator: unknown
Description: The Secretary of Energy is required by law to explore, prospect, conserve, develop, use, and operate the Naval Petroleum and Oil Shale Reserves. The Naval Petroleum Reserves Production Act of 1976 (Public Law 94-258), requires that the Naval Petroleum Reserves be produced at their maximum efficient rate (MER), consistent with sound engineering practices, for a period of six years. To fulfill this mission, DOE is proposing continued development activities which would include the drilling of approximately 250 oil production and injection (gas, water, and steam) wells, the construction of between 25 and 30 miles of associated gas, water, and steam pipelines, the installation of several production and support facilities, and the construction of between 15 and 20 miles of access roads. These drilling and construction estimates include any necessary activities related to the operation of the Rocky Mountain Oilfield Testing Center (RMOTC). The purpose of RMOTC will be to provide facilities and necessary support to government and private industry for testing and evaluating new oilfield and environmental technologies, and to transfer these results to the petroleum industry through seminars and publications. Continued development activities either have no potential to result in adverse environmental impacts or would only result in adverse ...

The durability of stabilized flue gas desulfurization sludge

The durability of stabilized flue gas desulfurization sludge

Date: December 31, 1995
Creator: Chen, X.; Wolfe, W.E. & Hargraves, M.D.
Description: The effects of freeze-thaw cycling on the strength and durability of samples of compacted, stabilized, wet flue gas desulfurization (FGD) by-products are reported. The results of laboratory tests show a clear relationship between higher water contents and increasing vulnerability to freeze-thaw effects. In the samples tested, water contents at or above 40% were characteristic of all the freeze-thaw specimens exhibiting low strengths. Lime content and curing time were also shown to have a marked influence on the durability of the FGD material. It was shown that samples can maintain good strength under freeze-thaw conditions provided 5% lime was added before compaction and the time from compaction to first freeze was at least 60 days.

Repository surface design site layout analysis

Repository surface design site layout analysis

Date: February 27, 1998
Creator: Montalvo, H.R.
Description: The purpose of this analysis is to establish the arrangement of the Yucca Mountain Repository surface facilities and features near the North Portal. The analysis updates and expands the North Portal area site layout concept presented in the ACD, including changes to reflect the resizing of the Waste Handling Building (WHB), Waste Treatment Building (WTB), Carrier Preparation Building (CPB), and site parking areas; the addition of the Carrier Washdown Buildings (CWBs); the elimination of the Cask Maintenance Facility (CMF); and the development of a concept for site grading and flood control. The analysis also establishes the layout of the surface features (e.g., roads and utilities) that connect all the repository surface areas (North Portal Operations Area, South Portal Development Operations Area, Emplacement Shaft Surface Operations Area, and Development Shaft Surface Operations Area) and locates an area for a potential lag storage facility. Details of South Portal and shaft layouts will be covered in separate design analyses. The objective of this analysis is to provide a suitable level of design for the Viability Assessment (VA). The analysis was revised to incorporate additional material developed since the issuance of Revision 01. This material includes safeguards and security input, utility system input (size ...

Corrective Action Investigation Plan for Corrective Action Unit 252: Area 25 Engine Test Stand 1 Decontamination Pad, Nevada Test Site, Nevada

Date: August 20, 1999
Creator: U.S. Department of Energy, Nevada Operations Office
Description: This Corrective Action Investigation Plan contains the U.S. Department of Energy, Nevada Operations Office's approach to collect the data necessary to evaluate corrective action alternatives appropriate for the closure of Corrective Action Unit 252 under the Federal Facility Agreement and Consent Order. Corrective Action Unit 252 consists of Corrective Action Site (CAS) 25-07-02, Engine Test Stand-1 (ETS-1) Decontamination Pad. Located in Area 25 at the intersection of Road H and Road K at the Nevada Test Site, ETS-1 was designed for use as a mobile radiation checkpoint and for vehicle decontamination. The CAS consists of a concrete decontamination pad with a drain, a gravel-filled sump, two concrete trailer pads, and utility boxes. Constructed in 1966, the ETS-1 facility was part of the Nuclear Rocket Development Station (NRDS) complex and used to test nuclear rockets. The ETS-1 Decontamination Pad and mobile radiation check point was built in 1968. The NRDS complex ceased primary operations in 1973. Based on site history, the focus of the field investigation activities will be to determine if any primary contaminants of potential concern (COPCs) (including radionuclides, total volatile organic compounds, total semivolatile organic compounds, total petroleum hydrocarbons as diesel-range organics, Resource Conservation and Recovery Act metals, ...

Environmental assessment for the Area 5 radioactive waste management site access improvement at the Nevada Test Site

Date: November 1, 1997
Creator: unknown
Description: The United States Department of Energy has prepared an Environmental Assessment which analyzes the potential environmental effects of improving access to its AREA 5 RWMS at the NTS. The EA evaluates the potential impacts of constructing an extension of the Cane Springs Road between Mercury Highway and the 5-01 Road. Three alternative actions are also evaluated: (1) construction of a new road along the existing alignment of the Powerline Road between Mercury Highway and the 5-01 Road, (2) upgrading the existing 5-01 Road, and (3) taking no action. The purpose and need for improving access to the RWMS are addressed in Section 1.0 of the EA. A detailed description of the proposed action and alternatives is in Section 2.0. Section 3.0 describes the affected environment and Section 4.0 the environmental effects of the proposed action and alternatives. Health and transportation effects, accident scenarios, cumulative effects, and other relevant information are found in Sections 5.0 through 12.0 of the EA. DOE determined that the alternative action of upgrading the existing 5-01 Road would best meet the needs of the agency.

The Road Patcher

Date: July 1, 1999
Creator: unknown
Description: I rebuilt the prototype machine to the point it was ready to go into a trial mode, however after Clark Machine Inc., took the contract. to build me four machines they wanted the prototype in their yard so they could build from it. They have built one machine complete and have almost all the parts to the other three built ready to assemble. I have inspected the one that is complete and so far everything looks fine, however the engineer needs to come back and check it out and stamp the drawings. Then comes OSA to inspect the machine. After all this I feel that we have a machine that is not only good in its field it will sell to contractors and firms that sell this type of equipment, after. all this is done we will contract for a truck and start to test the machine, in this way if there are any mistakes we can correct all four machines before finishing them. I have already started a complete method to contact these people, as a matter of fact, I sent out 10 last week and will keep sending out feelers until I hit someone who will appreciate what ...

Technical progress report: Peripheral mower blade. Sixth quarter report ending 12/31/99

Technical progress report: Peripheral mower blade. Sixth quarter report ending 12/31/99

Date: January 1, 2000
Creator: Darden, John A.
Description: Machine Tech Inc. has been assisting the author with the development of the peripheral mower blade decks. Machine Tech Inc. is still developing the batwing mower deck, which was started last fall after the completion of the mounted deck. The completion date of this program is slated for February. The wing covers and the center section of the batwing have been completed, the frame and drive-lines are now under development. Information from the nineteen-foot bat-wing deck prototype that they have been testing is now being used in the development of a more acceptable bat-wing mower. This unit will be able to maintain the same peripheral mower benefits, but will be much lighter and easier to pull requiring less fuel and damage to highway right of ways in soft areas. The mounted deck has been completed and is in the pilot stage with reports yet to be compiled. Machine Tech Inc. has also worked in an agricultural deck which is closely related to the mounted peripheral mower deck developed for the highway right of way. This will be one more outlet for the peripheral mower machines into the hands of the public.
