A Hybrid Approach To Expert And Model Based Effort Estimation., Daniel Ryan Baker
A Hybrid Approach To Expert And Model Based Effort Estimation., Daniel Ryan Baker
Graduate Theses, Dissertations, and Problem Reports (ETD)
It is important to have a good cost estimate in order to budget a new project. Unfortunately, software effort estimation methods are often inaccurate. Molokken and Jorgensen report that 60-80% of the time a software project will overrun its estimate by an average of 30% [98]. Furthermore, most estimates do not describe the uncertainty of the estimate [52,54,118]. In addition, each source of uncertainty, as described by Kitchenham and Linkman [68], has yet to be represented. In this thesis, the design principles of an effort estimation tool called 2CEE are discussed. This tool is currently being deployed at NASA’s Jet …

Essays In Trade, Foreign Aid And Investment. Essay 1: Motivation For Bilateral Aid Allocation: Altruism Or Trade Benefits. Essay 2: Does Institutional Quality Matter For Investment And Capital Mobility? Evidence From Sub -Saharan Africa. Essay 3: Do Donors Care About Declining Trade Revenue From Liberalization? An Analysis Of Aid Allocation. (With Subhayu Bandyopadhyay)., Javed Younas
Graduate Theses, Dissertations, and Problem Reports (ETD)
Essay 1: Motivation for bilateral aid allocation: Altruism or trade benefits. This paper argues that bilateral aid from developed OECD countries is disproportionately allocated to recipient nations who have a greater tendency to import goods in which donor nations have a comparative advantage in production. The estimates indicate that a substantially larger amount of aid per capita is provided to recipients who import capital goods, while imports by other category groups have no significant effects. Given that developed donor nations are major producers and exporters of capital goods, this result at least partially supports their trade benefits motive. On the …
Response And Time Allocation On Concurrent Variable -Interval Schedules Of Signaled And Unsignaled Reinforcement, Jeffrey Everly
Response And Time Allocation On Concurrent Variable -Interval Schedules Of Signaled And Unsignaled Reinforcement, Jeffrey Everly
Graduate Theses, Dissertations, and Problem Reports (ETD)
The present experiments were designed to evaluate accounts of how behavior is allocated on concurrent variable-interval (VI) VI schedules. The generalized matching law assumes that the proportion of behavior allocated to the two schedules will match the proportion of reinforcers obtained on the two schedules (Baum, 1974). An alternate view holds that under ideal conditions, behavior should "fix" almost exclusively at the richer schedule. The leaner schedule is only visited, or "sampled", when a reinforcer becomes available on that schedule (Houston & McNamara, 1981). Attempts were made to create optimal conditions for producing an ideal fix-and-sample response pattern. Pigeons were …

The Study Of Down-Hole Hydro-Cyclone Efficiency In Oil Wells Using Computational Fluid Dynamics, Ahmed A. Yusuf
The Study Of Down-Hole Hydro-Cyclone Efficiency In Oil Wells Using Computational Fluid Dynamics, Ahmed A. Yusuf
Graduate Theses, Dissertations, and Problem Reports (ETD)
Water is by far the largest waste stream associated with oil and gas production and it is unimaginable to find an oil reservoir absolutely free from connate water. Water management has become an important issue of hydrocarbon production, since the produced water increases as the field grows older and the cost of water handling, such as separation, treatment and repair is dramatically increasing. Down-Hole Separation (DOWS) and re-injection results in the production of oil to the surface, while portions of water are injected to the underground formation without ever being lifted to the surface.;DOWS depends on geological characteristics of the …

Determining Low Permeability Formation Properties From Absolute Open Flow Potential, Fatemeh Belyadi
Determining Low Permeability Formation Properties From Absolute Open Flow Potential, Fatemeh Belyadi
Graduate Theses, Dissertations, and Problem Reports (ETD)
Absolute Open Flow Potential (AOFP) is often the only productivity information available from low permeability gas formations particularly in the Appalachian Basin. Absolute Open Flow Potential (AOFP) is commonly evaluated through a single point test due to its cost effectiveness. In low permeability reservoirs, the time required for obtaining stabilized flow rate is often very long. Therefore, stabilized AOFP may not be achieved in short tests. Furthermore, most low permeability gas wells are hydraulically fractured to improve their productivity. Therefore, the post-fracture measured AOFP could be significantly influenced by fracture properties.;The objective of this was to develop a methodology to …
