Book Description
Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1 957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna tional publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 29 (thesis year 1984) a total of 12,637 theses titles from 23 Canadian and 202 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work. While Volume 29 reports theses submitted in 1984, on occasion, certain univer sities do report theses submitted in previous years but not reported at the time.

Book Description
Decisions to accelerate construction schedules--increasing craft manning levels above what is considered normal levels--usually reduce craft efficiency. This article examines the relationship of relative manning levels to craft productivity and the relationship between manning density and productivity, all for the purpose of providing a reference point for estimating optimum project manning levels when translating man-hour inefficiencies estimated by multiple regression equations into dollars. In doing so, it explains the negative effects of compressing construction schedules and the literature on quantifying the relationship between manning levels and craft productivity. It then discusses a study involving the construction productivity losses for a nuclear power plant, one that describes a multiple regression analysis that uses such variables as construction duration, project size, number of units, nuclear reactor type, construction complexity, and location. It also details the results of the regression analysis in relation to three categories of construction: concrete, large bore pipe, and electrical work. It suggests that regression analysis enables project managers to measure the relationship between craft manpower density and bulk commodity unit rates for both nuclear power construction projects and other large-scale industrial construction projects.

Book Description
Project management is a leadership function primarily concerned with the organization, coordination and control of large undertakings, with the aim of achieving technical excellence, by working to quality standards, optimizing the schedule and the supply chain and minimizing costs. Competent project management can reduce costs through more efficient work sequences, higher productivity, shorter activity durations and the parallel reduction of accumulated interest during construction of nuclear power plants. Based on past proven practices in Member States, this publication provides advice and gu.

Book Description
One of the most important jobs of a project manager is to manage a project's budget and schedule. These tasks can easily be very difficult to accomplish on projects that are complex, especially since successful project execution relies heavily on people who are expected to perform their roles individually and as a team. One of the most difficult aspects of managing projects is estimating how fast and effectively humans will perform a task; that is, determining how productive workers collectively will be each day, each week, or within any time period during the life of a project. Because projects are unique and are typically one-off endeavors, there is usually little previous empirical data to rely upon for the project manager to forecast productivity before or during the project's execution. The crux of the problem lies with adequately identifying not only the labor work flow process, but also the influences that affect the work flow process. When scope changes are introduced into the work flow of a project, the types and number of influences and their cause and effect relationships can significantly increase in numbers. This phenomenon often turns complicated projects into extremely complex ones and the final outcome can be greater than the sum of the individual inputs. For project managers who are unable to get their arms around this very real situation, forecasting the outcome of a project often becomes out of control, especially for projects that are large and heavily labor intensive. This study takes a post-positivist approach to design and builds a system dynamic model with which construction projects that are delivered using the design-bid-build methodology can be simulated to show generically how the influences that affect construction projects can affect worker productivity. No other studies are known to exist that design or build such a model for construction projects that use the design-bid-build delivery method. The model that was designed in the study is based on the works of several academics' works as well as the input of several experts in the construction field, including this study's author. As opposed to attempting to create a simulation model based on the uniqueness of a single project, a "mosaic" approach was used in creating the model in that elements of the model were identified and taken from studies found through the literature review as well as interviews with construction industry experts. The stock and flow structure of the study's model is intended to be a composite of many construction projects and can be used for any project delivered using the design-bid-build methodology. From the research, the model was created and tested using good modeling practice in that the model testing phase followed the process created by one of the pre-eminent system dynamic modelers in the world (refer to Sterman, 2000). The result is a model that simulates the work flow of labor hours in a design-bid-build construction project which can be affected by an immeasurable number of influences that can and do occur on construction projects.

Book Description
What is Project Independence? The sources and uses of energy in the United States have changed dramatically in the last several decades. As a result, in just one generation, we have shifted from a position of domestic energy abundance to a substantial and continually growing reliance on foreign energy sources. Project Independence is a wide-ranging program to evaluate this growing dependence on foreign sources of energy, and to develop positive programs to reduce our vulnerability to future oil cut-offs and price increases.

Book Description
Several individuals noted the potentially important civilian uses of atomic energy shortly after the bombings of Hiroshima and Nagasaki in 1945. That year J. Robert Oppenheimer told a national radio audience that "in the near future" it would be possible to generate profitable electric power from "controlled nuclear chain reaction units" (reactors). It was suggested that, after fIfteen to twenty-five years of development, mature nuclear technology could provide virtually inexhaustible, cheap energy given the abundance of nuclear fuel. Admiral Lewis Strauss, the Chairman of the Atomic Energy Commission, stated that atomic power would generate electricity "too cheap to meter" (A statement that, according to Brookhaven National Laboratories' physicist Herbert Kouts, immediately "caused consternation among his technical advisors" [Kouts, 1983: 3)). For a brief period it was thought that airplanes would fly using atomic power, and homes would install small nuclear reactors for heat and hot water. 1950s and early 1960s a small number of prototype nuclear In the reactors came on line in the United States. The first power plant protoype reactor began operation in Shippingport, Pennsylvania in 1957. It was followed by the Dresden 1 unit near Chicago in 1959, the Yankee plant in Rowe, Massachusetts (1960), and the Indian Point (New York) and Big Rock Point (Michigan) plants in 1%2. These five plants had a combined 800 megawatts (800 MW), or less than one generating capacity ofless than percent of the total American electricity generating capacity in 1962.
