The advent of Service Oriented Architecture (SOA) paradigm and increasing use of Web Services (WS) implies that the future will see a large number of services transferred between providers and consumers, using many applications or agents working on behalf of humans. Discovering and using the services is the easy part. Negotiating and selecting the best services from amongst the plethora of similar ones, depending on their cost and quality, is the challenging issue. However, existing WS-I standards neither cater to provision of Service Level Agreements (SLAs), nor their exchange between parties. These standards are confined merely to WS description (WSDL). …

Beosh: The Beowulf Cluster Shell, Mason E. Vail

Computer Science Graduate Projects and Theses

The Beowulf Cluster Shell (beosh) has been created to provide cluster users with a Single System Image (SSI) by distributing individual commands or pipelined jobs over available nodes without requiring the user to be aware of where or how jobs are distributed. Job control of distributed jobs enables management of multiple concurrent remote jobs from a single shell session. In addition to SSI features, beosh supports parallel job execution through pdsh, a commonly used parallel-only cluster shell. In either distributed or parallel mode, beosh can limit nodes to those reserved through a system like the Portable Batch System (PBS).

Synthesis Of Lanthanum-Strontium Manganites By Oxalate-Precursor Co-Precipitation Methods In Solution And In Reverse Micellar Microemulsion, Vuk Uskoković, Miha Drofenik

Pharmacy Faculty Articles and Research

Nanostructured lanthanum–strontium manganites were synthesized using two different co-precipitation approaches, one in bulk solution, and the other in reverse micelles of CTAB/1-hexanol/water microemulsion. In both cases, precursor cations were precipitated by using oxalic acid. The properties of the materials synthesized by using these two methods were compared in order to reveal potential advantages of the microemulsion-assisted approach. The influence of the annealing conditions on the properties of synthesized manganites was investigated by using X-ray diffraction, transmission electron microscopy, differential thermal analysis, thermogravimetric analysis and magnetic measurements.

Six Levels Of Financial Knowledge, George E. Manners Jr.

Faculty Articles

With the appropriate framework to shape financial knowledge, the management accounting function should become an organization's principal decision-support platform. The framework consists of six levels of financial knowledge, and the word "financial" is most operative here. The Level 1 knowledge base connects a business to the outside world. When you have output volume and variable cost per output unit, you have the basis for Level 2 vocabulary. When a business transitions to Level 3, it has learned that return on assets must be employed as the enterprise's guiding profitability gauge. There is a very distinct increment in knowledge when moving …

Finding Least Expensive Tolerance Solutions And Least Expensive Tolerance Revisions: Algorithms And Computational Complexity, Inna Pivkina, Vladik Kreinovich

Departmental Technical Reports (CS)

For an engineering design, tolerances in design parameters are selected so that within these tolerances, we guarantee the desired functionality. Feasible algorithms are known for solving the corresponding computational problems: the problem of finding tolerances that guarantee the given functionality, and the problem of checking whether given tolerances guarantee this functionality.

In this paper, we show that in many practical problems, the problem of choosing the optimal tolerances can also be solved by a feasible algorithm. We prove that a slightly different problem of finding the optimal tolerance revision is, in contrast, computationally difficult (namely, NP-hard). We also show that …

Characterization And Feasibility Study Of A Near Infrared Ccd Imager For Monitoring Tumor Hemodynamics, Manan Goel

Bioengineering Theses - Archive

Prostate cancer is one of the most common types of cancers diagnosed among North American men. Chemotherapy is generally used to target advanced metastatic prostate cancer. Near infrared spectroscopy (NIRS) has been previously investigated to monitor the hemodynamic changes in rat prostate tumors; however, the previous study with NIRS is limited by its spatial resolution. The goal of this study is to characterize an NIR, CCD imager and to explore the feasibility of using the CCD imager to non-invasively monitor hemodynamic changes in rat prostate tumors during gas intervention. Firstly, studies were conducted to characterize the CCD imager and understand …

Investigation Of The Suitability Of The Biscatecholborate Anion As A Reductive Quencher For Photoexcited Ruthenium Polyphyridyl Complexes, Alper Yarasik

Chemistry & Biochemistry Theses - Archive

Ruthenium polypyridyl complexes [Ru(L-L)3]2+, (L-L = 1,10 - phenanthroline or 2,2'- bipyridine) which covalently linked to electron donor or acceptor units are frequently used in artificial photosystems because of their high emission quantum yields, long excited-state lifetimes, favorable redox properties and excellent chemical stability. The ruthenium dimer P, [(phen)2Ru(tatpp)Ru(phen)2][PF6]4, undergoes multiple photoreductions in the presence of donors such as triethylamine (TEA); however, large amount of donors (0.3 M) are required for efficient reductions. This explores the use of a anionic donor such as [B(cat)2]- with the hypothesis that ion-pairing will result in lower required concentration of the donor. Electrochemical data …

Generalization And Enforcement Of Role-Based Access Control Using A Novel Event-Based Approach, Raman Adaikkalavan

Computer Science and Engineering Dissertations - Archive

Protecting information against unauthorized access is a key issue in information system security. Advanced access control models and mechanisms have now become necessary for applications and systems due to emerging acts, such as the Health Insurance Portability and Accountability Act (HIPAA) and the Sarbanes-Oxley Act. Role-Based Access Control (RBAC) is a viable alternative to traditional discretionary and mandatory access control. RBAC has been shown to be cost effective and is being employed in various application domains on account of its characteristics: rich specification, policy neutrality, separation of duty relations, principle of least privilege, and ease of management. Existing RBAC approaches …

Learning State And Action Space Hierarchies For Reinforcement Learning Using Action-Dependent Partitioning, Mehran Asadi

Computer Science and Engineering Dissertations - Archive

Autonomous systems are often dicult to program. Reinforcement learning (RL) is an attractive alternative, as it allows the agent to learn behavior on the basis of sparse, delayed reward signals provided only when the agent reaches desired goals. Recent attempts to address the dimensionality of RL have turned to principled ways of exploiting temporal abstraction, where decisions are not required at each step, but rather invoke the execution of temporally-extended activities which follow their own policies un- til termination. This leads naturally to hierarchical control architectures and associated learning algorithms. This dissertation reviews several approaches to temporal abstraction and hierarchical …

Some Preservation Techniques For (Deep Water) Coral Samples For Subsequent Molecular Studies: A Special Supplement From Harbor Branch Oceanographic Institute, Jose V. Lopez

Marine & Environmental Sciences Faculty Reports

Around the time that the thirteen original Atlantic colonies were fighting for independence from Britain, there existed little agreement among naturalists as to the nature of corals. Were they inanimate (stones), plants, animals, or intermediate between the latter two (zoophytes)? This diversity of definition and opinions undoubtedly produced considerable confusion and disagreement among naturalists interested in such things. The symbiotic nature of algal cells in the tissues of some corals was also not well understood. It was not until the Darwinian period in the nineteenth century that little doubt remained, and therefore it was generally agreed, that corals were actually …

Hybrid Atomistic-Coarse-Grained Treatment Of Multiscale Processes In Heterogeneous Materials: A Self-Consistent-Field Approach, Dennis J. Diestler, H. Zhou, Ruqiang Feng, Xiao Cheng Zeng

Xiao Cheng Zeng Publications

A treatment of multiscale quasistatic processes that combines an atomistic description of microscopic heterogeneous (“near”) regions of a material with a coarse-grained (quasicontinuum) description of macroscopic homogeneous (“far”) regions is presented. The hybrid description yields a reduced system consisting of the original atoms of the near regions plus pseudoatoms (nodes of the coarse-graining mesh) of the far regions, which interact through an effective many-body potential energy V_eff that depends on the thermodynamic state. The approximate nature of V_eff gives rise to “ghost forces,” which are reflected in spurious heterogeneities close to interfaces between near and far regions. The …

Novel Approaches To Photoassisted Deposition Of Semiconductors And Nanocomposite Materials, Sashikala Somasundaram

Chemistry & Biochemistry Dissertations - Archive

This dissertation research begins with the use of TiO2-based photocatalysis for the reduction of metal ions with very negative reduction potentials. The indirect photocatalytic reduction of four metal ions: Cd2+, Zn2+, Mn2+, and Tl+ using formate radical anions generated in UV-irradiated aqueous TiO2 suspensions, is described. Using Tl+ as a model metal ion, a simple kinetics scheme was developed for the indirect reduction route, and the predictions from this model were shown to be in excellent agreement with experimental data. Titania-based photocatalysis was then used for the preparation of MSe/TiO2 "coupled" semiconductors. Heterogeneous photocatalysis using photoexcited TiO2 substrates was shown …

Peak Streamflow Estimation For Kentucky Streams Using Historical Streamflow Records., John Edwin Spalding Jr., 1982-

Electronic Theses and Dissertations

This work develops a method of estimating peak daily streamflow, Qpeak, for Kentucky streams using daily average streamflow, Qave, data from the United States Geological Survey's (USGS) National Water Information System (NWIS) website. The purpose of doing this is to develop a systematic approach to increase the number of Qpeak values available for frequency analysis. Specifically, the enhanced record of Qpeak values will allow estimation of flood flow magnitudes with recurrence intervals of less than one year. Stream gages with drainage areas less than 1,000 square miles are examined to analyze stream corridors that are most commonly considered for stream …

Multiobjective Simulation-Based Methodologies For Medical Decision Making., Ahmed Hassan Youssefagha

Electronic Theses and Dissertations

A variety of methodologies have been employed for decision making related to the treatment of diseases/injury. Decision trees are a functional way in which to examine problems under uncertainty by providing a method to analyze decisions under risk (Detsky, 1996, 97). However, conventional decision trees do not completely represent "the real world" since they cannot investigate problems that are cyclic in nature (Jaafari, 2003). The stochastic tree that developed Hazen during 1992-to-1996 is one of the most relevant methods and techniques related to decision analyses that append more incorporation for medical intervention related to recurring diseases/injuries. "The approach combines features …

Teacher Education Accreditation : A Review Of National And International Trends And Practices, Lawrence Ingvarson, Alison Elliott, Elizabeth Kleinhenz, Phillip Mckenzie

Initial Teacher education

In June 2005 the National Institute for Quality Teaching and School Leadership commissioned ACER to conduct a project to provide advice on developing a national system for the accreditation of pre-service teacher education programs. The project brief fell into two main sections. The first was to conduct a literature review examining: (a) Current accreditation and course approval policies and practices in Australia to identify similarities and differences and implications for a national accreditation system; (b) Developments in the accreditation of teacher education programs in other countries and whether any of the identified approaches could provide a basis for a national …

The Impact Of Reading Programs As A Map Project Strategy, Tena Jones

Masters Theses & Specialist Projects

The No Child Left Behind (NCLB) Act of 2001 was enacted to protect the United States' most vulnerable students and was signed into law in January 2002 (U.S. Department of Education, 2002). For many years, black, Hispanic, special education, and limited English proficient students were not achieving at the same level as their white, middle-class counterparts because schools were not held accountable for their individual progress. The achievement gap is well documented in previous research at all levels of education. Scores on the National Assessment of Educational Progress  (NAEP) from 1996 to 2000, obtained from a national sample of 8th- …
