Repair of Waterstop Failures: Case Histories

Description: This report discusses case studies of failures in waterstops that prevent water passage through the monolith joints of concrete dams and locks. "The primary objective of this study was to identify materials and techniques which have been used in repair of waterstop failures. Also, based on a review and evaluation of current practices, a secondary objective was to identify those areas where research is needed to supplement existing technology" (abstract).

Care and Repair of Farm Implements: No. 5, Grain Separators

Description: "An enormous waste of grain and great loss of time result every year through the inefficient work of thrashing machines that are not properly repaired and put in thorough working condition before the beginning of the working season.... The separator should be overhauled at the close of the thrashing season or during the winter, needed parts ordered, and necessary repairs and adjustments made. This will tend to lengthen the life of the machine, and prevent loss of time and money from breakdowns at the busy season. This bulletin gives instructions for overhauling and adjusting separators which will reduce to the minimum the losses and delays from breakdowns during the operating season." -- p. 2

Wind turbine reliability : a database and analysis approach.

Description: The US wind Industry has experienced remarkable growth since the turn of the century. At the same time, the physical size and electrical generation capabilities of wind turbines has also experienced remarkable growth. As the market continues to expand, and as wind generation continues to gain a significant share of the generation portfolio, the reliability of wind turbine technology becomes increasingly important. This report addresses how operations and maintenance costs are related to unreliability - that is the failures experienced by systems and components. Reliability tools are demonstrated, data needed to understand and catalog failure events is described, and practical wind turbine reliability models are illustrated, including preliminary results. This report also presents a continuing process of how to proceed with controlling industry requirements, needs, and expectations related to Reliability, Availability, Maintainability, and Safety. A simply stated goal of this process is to better understand and to improve the operable reliability of wind turbine installations.

Application of Diagnostic/Prognostic Methods to Critical Equipment for the Spent Nuclear Fuel Cleanup Program

Description: The management of the Spent Nuclear Fuel (SNF) project at the Hanford K-Basin in the 100 N Area has successfully restructured the preventive maintenance, spare parts inventory requirements, and the operator rounds data requirements. In this investigation, they continue to examine the different facets of the operations and maintenance (O&M) of the K-Basin cleanup project in search of additional reliability and cost savings. This report focuses on the initial findings of a team of PNNL engineers engaged to identify potential opportunities for reducing the cost of O&M through the application of advanced diagnostics (fault determination) and prognostics (residual life/reliability determination). The objective is to introduce predictive technologies to eliminate or reduce high impact equipment failures. The PNNL team in conjunction with the SNF engineers found the following major opportunities for cost reduction and/or enhancing reliability: (1) Provide data routing and automated analysis from existing detection systems to a display center that will engage the operations and engineering team. This display will be operator intuitive with system alarms and integrated diagnostic capability. (2) Change operating methods to reduce major transients induced in critical equipment. This would reduce stress levels on critical equipment. (3) Install a limited sensor set on failure prone critical equipment to allow degradation or stressor levels to be monitored and alarmed. This would provide operators and engineers with advance guidance and warning of failure events. Specific methods for implementation of the above improvement opportunities are provided in the recommendations. They include an Integrated Water Treatment System (IWTS) decision support system, introduction of variable frequency drives on certain pump motors, and the addition of limited diagnostic instrumentation on specified critical equipment.

Shared Norms, Hierarchical Maintenance, and International Hierarchy

Description: The dissertation studies two aspects of international hierarchy. The world of international politics is not one of completely sovereign states competing in anarchy. Patterns of hierarchy, where a dominant state has legitimate control over some actions of a subordinate state, color the globe. First, I look at shared norms and hierarchy. Most studies concerning hierarchy focus on material maximization as an explanation for hierarchy--if hierarchy increases the wealth and security of two states, then hierarchy is more likely. I argue that shared norms held by two states facilitate hierarchy. Shared norms produce a common in-group community, generate common interests, create common ways of doing business, and give rise to common values that increase subordinate states' ability to persuade the dominant state. These factors ease the creation and maintenance of international hierarchical relationships. Second, I study interstate behaviors that can be explained as actions of maintenance by dominant states over subordinates to preserve or increase a level of hierarchy. I theorize that sticks and carrots from a dominant state (like economic sanctions, military interventions, and foreign aid) help sustain a dominant state's rule by convincing subordinate states to follow the dominant state's commands and expectations. Using data on U.S. hierarchies from 1950 to 2010, I utilize multivariate regressions to test hypotheses drawn from these theories. I find that shared norms associate with hierarchy, and maintenance actions uncommonly associate with compliance.

Rehabilitation of the South Jetty, Ocean City, Maryland

Description: Partial abstract: Frequent dredging requirements and scouring at the foundation of Ocean City Inlet's south jetty resulted in a study to determine the source of the shoaling and scouring. The study concluded that sand was being transported northward along Assateague Island, through and over the south jetty, and deposited inside the inlet. The sand was then transported north by ebb currents where it encroached on the Federal navigation channel. A rehabilitation program was initiated to create a littoral barrier to eliminate the shoaling problem and to repair the scour hold. Three headland breakwaters were constructed to stabilize Northern Assateague Island. The site was selected as part of the Monitoring Completed Coastal Projects (MCCP) Program to determine how well the rehabilitation project accomplished its design purpose.

The Development and Implementation of Federal Policy Concerning Health Maintenance Organizations

Description: There is some controversy which centers around the question of whether a particular government policy or program may be Judged successful. This dissertation takes the position, with due respect to the difficulties of such a task, that policy success can be evaluated and that it is important that such evaluations be made. Traditionally, health care in the United States has been delivered by the solo medical practitioner on a fee-for-service basis. A relatively new concept in the health care delivery system combines group practice with prepayment for services. These types of practices were designated as Health Maintenance Organizations in 1970 by the Nixon Administration.The major question of this dissertation is whether or not the HMO policy of the federal government has been a success. Along with this question the primary focus of this dissertation is upon the development and evolution of the federal HMO program.
