Mixture Model Clustering For Very Large Data Sets., Leong Siow Hoo Jan 2010

Mixture Model Clustering For Very Large Data Sets., Leong Siow Hoo

Student Works (2010-2019)

This thesis develops mixture model clustering algorithms scalable to data sets that do not fit into the computer memory buffer. Two algorithms, FlexClust and FlexClustMix, are proposed for clustering very large continuous and mixed data sets respectively. The basic framework of the algorithms is to scale down data incrementally using data compression, and incorporates the later compressed data into the current model with the ability to recover new clusters that have been missed out in the earlier compressed data. It consists of three modules: 1) incremental compression, 2) detecting change in cluster structure, and 3) update of current model. In …

Inter-Phase Mass Transport: Modelling Of Air-Water Movement Of Organic Chemicals, Darryl Hawker, Benjalak Karnchanasest Jan 2010

Inter-Phase Mass Transport: Modelling Of Air-Water Movement Of Organic Chemicals, Darryl Hawker, Benjalak Karnchanasest

Applied Environmental Research

Air-water inter-phase mass transport of organic contaminants is often an important factor in their environmental fate and behaviour. The equilibrium situation is given by the Henry's Law Constant of the compound, but is rarely attained under environmental conditions. Approach to equilibrium is commonly described by the two-film theory involving molecular (Fickian) diffusion through thin stagnant films adjacent to the air-water interface. This theory is formulated in terms of mass transfer coefficients and fugacity transport parameters. Penetration and Surface Renewal Theories of mass transfer are also discussed. The importance of the Henry's Law Constant (H) is shown. Compounds such as phenol …

Durian Peel As Biosorbent For Removal Of Cadmium Ions From Aqueous Solution, Wanna Saikaew, Pairat Kaewsarn Jan 2010

Durian Peel As Biosorbent For Removal Of Cadmium Ions From Aqueous Solution, Wanna Saikaew, Pairat Kaewsarn

Applied Environmental Research

The ability of durian peel to remove Cd(II) ions from aqueous solution by biosorption was investigated. The sorption capacities at different solution pH, agitation speed, temperatures, initial cadmium ions concentrations and contact time were evaluated on a batch scale basis. At pH 5 and agitation speed 150 rpm, the cadmium ions removal reached at a maximum value. Increases in cadmium capacity with increasing temperature indicated endothermic nature of the biosorption process. The equilibrium was better described by the Langmuir isotherm model, with a maximum biosorption capacity of 18.55 mg g-1. The biosorption was relatively quick about 15 min to reach …

Analysis Of Carrion Fly (Diptera: Calliphoridae) Population Genetics Using Amplified Fragment Length Polymorphism (Aflp) Profiles., Christine J. Picard Jan 2010

Analysis Of Carrion Fly (Diptera: Calliphoridae) Population Genetics Using Amplified Fragment Length Polymorphism (Aflp) Profiles., Christine J. Picard

Graduate Theses, Dissertations, and Problem Reports (ETD)

Worldwide, there are over 1000 species of blow flies (Diptera: Calliphoridae). Blow flies display a variety of habits, however they are best known for their role in the decomposition of carrion. As yet, there are few studies of their population genetic structure, although such data would contribute to such fields as pest management, taxonomy, forensic entomology and veterinary medicine. Although it is typically assumed that carrion fly populations are panmictic, this has been disputed. This research focused on developing a new protocol to understand the population genetic structure in carrion flies using amplified fragment length polymorphism (AFLP) profiles. My specific …

Microfranchising: A Business Approach To Fighting Poverty, Deborah Burand, David W. Koch Jan 2010

Microfranchising: A Business Approach To Fighting Poverty, Deborah Burand, David W. Koch

Articles

Imagine a franchise network that trains, guides, and supports hundreds of poor women with little or no business experience to become successful business owners. Such "microfranchise" efforts, though relatively small in number, have been gathering steam in the development community and, recently, attracting the attention of the mainstream franchising indus- Deborah Burand try. Advocates have seized on microfranchising as a natural complement or follow-on to the widely acclaimed successes of the "microfinance" sector, which provides small-scale finance services to over 150 million of the world's poor. Microfranchising today is where microfinance was a decade or more ago. It is appropriate …

Artificial Neural Networks For Reservoir Level Detection Of Carbon Dioxide Seepage Location Using Permanent Down-Hole Pressure Data., Jalal Jalali

Graduate Theses, Dissertations, and Problem Reports (ETD)

Monitoring the potential seepage of CO2 is a required practice for any CO2 sequestration project. Monitoring is used in order to ensure the efficiency of the sequestration process and that the CO 2 will remain in the target formation for extended periods of time. Different techniques that exist in the literature differ based on their resolution and location of their application. Monitoring techniques can be divided into three categories: surface techniques, which measure CO2 at or above the surface, shallow depth techniques, which monitor the concentration of CO2 in soil or shallow aquifers, or deep techniques, which monitor CO2 movement …

Considering The Curricular Impact Of Lactation Consulting/Counseling On Breastfeeding Decisions Within Two West Virginia County Wic Programs., Joni M. Johnson Gray

Graduate Theses, Dissertations, and Problem Reports (ETD)

Due to a glaring absence of research into the breastfeeding decisions of Appalachian women, this study investigates the potential influences of the WIC program and its counseling on the infant feeding decisions of West Virginia women. Using the lens of critical theory, the study employs a mixed methods research approach, including the distribution of a breastfeeding perception survey, extended interviews with WIC lactation consultants and an analysis of WV WIC’s proposed and practiced breastfeeding education curriculum. Results suggest that WV mothers are informed about the benefits of breastfeeding, but not necessarily from interactions with the WIC program. Rather, a latent …

American government rests on the principle of distrust of government. Not only is power within the federal government checked and balanced. Power is divided between the federal government and the state governments. So what if a state law conflicts with a federal law? The Constitution says that the "Constitution, and the Laws of the United States ... shall be the supreme Law of the Land; ... any Thing in the ... Laws of any State to the Contrary notwithstanding." Sometimes the conflict between federal and state law is obvious and the Supremacy Clause is easily applied. But sometimes ...

Numerical Modeling Of Near-Surface Carbon Dioxide Migration With Barometric Pumping Effects., Guoxiang Liu Jan 2010

Numerical Modeling Of Near-Surface Carbon Dioxide Migration With Barometric Pumping Effects., Guoxiang Liu

Graduate Theses, Dissertations, and Problem Reports (ETD)

With anthropogenic activities, the concentration of CO2 in the atmosphere has dramatically risen, very likely resulting in global warming and climate change. Capturing and disposing of the produced CO2 in geological formations can mitigate this problem provided that there is no substantial leakage from the subsurface back to atmosphere for hundreds of years. The detection of any CO2 leakage is essential to verify that the sequestration is effective, to initiate corrective actions if leakage is discovered, and to accurately assign storage credits in a "cap and trade" regulatory system. Natural fluctuations in atmospheric pressure are one factor that influences the …

Reply To Becker And Fuest, James R. Hines Jr.

Articles

It is an understatement to say that the appropriate taxation of foreign business income is a controversial and potentially confusing topic. One of the mysteries of international taxation has been that the prescriptions of what, until recently, was the accepted academic wisdom differs so sharply from widespread international practice. In an important contribution, Richman (1963) noted that a home government confronted with the choice of where it would prefer one of its resident taxpayers to allocate a single unit of capital would weigh the after-foreign-tax return from investing abroad against the pre-tax return from investing at home. From this observation, …

Of Coase, Calabresi, And Optimal Tax Liability, Kyle D. Logue, Joel Slemrod

Articles

The Article proceeds as follows. Part II offers a primer on the Coase Theorem, beginning with the classic case of neighbor externalizing on neighbor (farmer and rancher), and it explains the basic invariance propositions. Part III shifts the focus to Coasean situations involving buyers and sellers in a market or contractual relationship, buyers and sellers whose market interactions cause harm to third parties. Using supply-and-demand diagrams, we illustrate (in a new way) some of the most basic findings of the economic analysis of law, including both the Coasean invariance and efficiency propositions and the Calabresian least-cost avoider idea. Also in …

Is "Pay-To-Play" Driving Public Pension Fund Activism In Securities Class Actions? An Empirical Study, David H. Webber Jan 2010

Is "Pay-To-Play" Driving Public Pension Fund Activism In Securities Class Actions? An Empirical Study, David H. Webber

Faculty Scholarship

The recent emergence of public pension funds as frequent lead plaintiffs in securities class actions has prompted speculation that the funds’ litigation activism is driven by “pay-to-play”. “Pay-to-play” posits that public pension funds are driven by politician board members to obtain lead plaintiff appointments in securities class actions because of campaign contributions made by plaintiffs’ lawyers to those board members. This paper provides a comprehensive analysis of the securities litigation activity of 111 such funds from the years 2003 through 2006. Three of the paper’s findings cast doubt on the “pay-to-play” theory, including that: (1) politicians and political control negatively …

Optimal Antitrust Enforcement, Dynamic Competition, And Changing Economic Conditions, Keith N. Hylton, Haizhen Lin Jan 2010

Optimal Antitrust Enforcement, Dynamic Competition, And Changing Economic Conditions, Keith N. Hylton, Haizhen Lin

Faculty Scholarship

The recent financial crisis and recession provide an opportunity to reexamine the dynamic versus static efficiency tradeoff in antitrust enforcement policy. We examine implications of the optimal antitrust enforcement model when dynamic efficiency is incorporated. The “dynamic enforcement model” examined here provides a positive theory of Section 2 doctrine, some suggestions for modifying enforcement in light of its dynamic costs, and implies antitrust enforcers should put a greater weight on dynamic efficiency during recessions.
