Database Concepts In A Virtual World, Janet L. Ochs 2010 Regis University

Database Concepts In A Virtual World, Janet L. Ochs

All Regis University Theses

This project explored the use of a 3-D virtual world in an introductory database course to reduce the amount of time required to learn database concepts. A Second Life 3-D model was built to clarify database concepts and students used the model to create a Microsoft Access inventory database. Thereafter, the students provided feedback by answering a voluntary survey. Eighty two percent of the students surveyed agreed that the 3-D model clarified terms such as records, tables, primary keys and relationships. Seventy five percent of the students believed that the model reduced the amount of time required to learn these ...


Characterization Of Pollen Particles Using Lidar, Leda Sox 2010 Utah State University

Characterization Of Pollen Particles Using Lidar, Leda Sox

Leda Sox

We have observed pollen in the local troposphere using the depolarization capabilities of a LIDAR (Light Detection and Ranging) system. The polarization characteristics of the received LIDAR signal, along with supplemental pollen forecast data, allowed me to characterize the shape of the pollen particles.


Accurate Description Of The Optical Response Of A Multilayered Spherical System In The Long Wavelength Approximation, H. Y. Chung, G. Y. Guo, Hai-Pang Chiang, D. P. Tsai, P.T. Leung 2010 Portand State University

Accurate Description Of The Optical Response Of A Multilayered Spherical System In The Long Wavelength Approximation, H. Y. Chung, G. Y. Guo, Hai-Pang Chiang, D. P. Tsai, P.T. Leung

Physics Faculty Publications and Presentations

The optical response of a multilayered spherical system of unlimited number of layers (a “matryoshka”) in the long wavelength limit can be accounted for from the knowledge of the static multipole polarizability of the system to first-order accuracy. However, for systems of ultrasmall dimensions or systems with sizes not-too-small compared to the wavelength, this ordinary quasistatic long wavelength approximation (LWA) becomes inaccurate. Here we introduce two significant modifications of the LWA for such a nanomatryoshka in each of the two limits: the nonlocal optical response for ultrasmall systems (<10 >nm), and the “finite-wavelength corrections” for systems ∼100 nm. This is accomplished ...


Deep Packet Inspection And Its Effects On Net Neutrality, Michael A. DeRose 2010 Regis University

Deep Packet Inspection And Its Effects On Net Neutrality, Michael A. Derose

All Regis University Theses

Deep packet inspection (DPI) is becoming increasingly important as a means to classify and control Internet traffic based on the content, applications, and users. Rather than just using packet header information, Internet Service Providers are using DPI for traffic management, routing and security. But by being able to control traffic by content, a growing number of public policy makers and users fear ISPs may discriminately charge more for faster delivery of their data, slow down applications or even deny access. They cite such practices as endangering the principle of net neutrality; the premise that all data on the Internet should ...


Exploring The Benefits Of Buying Industry Leading It Infrastructure In A Healthcare Setting, Frank Biondolillo 2010 Regis University

Exploring The Benefits Of Buying Industry Leading It Infrastructure In A Healthcare Setting, Frank Biondolillo

All Regis University Theses

IT infrastructure leaders are under growing pressure to balance the demand for new and rapidly changing technologies in an era of fixed or declining IT budgets. They must buy wisely, make sure that every infrastructure dollar is spent wisely, and ensure it all fits into a preconceived plan that supports the organization's mission. This research looks at the IT literature, develops a qualitative research methodology and presents findings from a new study of IT infrastructure decision making in the healthcare industry. The findings show that healthcare technology leaders are building critical components of their infrastructure using the top two ...

Faculty Publications

Here, we report the initial observations of distributions of polycyclic aromatic hydrocarbons (PAH) in subsurface waters near the Deepwater Horizon oil well site (also referred to as the Macondo, Mississippi Canyon Block 252 or MC252 well). Profiles of in situ fluorescence and beam attenuation conducted during 9-16 May 2010 were characterized by distinct peaks at depths greater than 1000 m, with highest intensities close to the wellhead and decreasing intensities with increasing distance from the wellhead. Gas chromatography/mass spectrometry (GC/MS) analyses of water samples coinciding with the deep fluorescence and beam attenuation anomalies confirmed the presence of polycyclic ...

Integrating Environmental Science And Management: The Role Of System Dynamics Modelling, Kristin den Exter 2010 Southern Cross University

Integrating Environmental Science And Management: The Role Of System Dynamics Modelling, Kristin Den Exter

Dr Kristin den Exter

Institutional and epistemological differences between science and management present a challenge to the implementation of sustainable environmental management. Environmental problems are complex and require at least multidisciplinary, but most effectively transdisciplinary approaches for learning, understanding, decision-making and problem solving. This means building bridges between institutional and epistemological differences. The role of system dynamics modelling in integrating environmental science and management is examined in this thesis. An action research methodology is adopted where, over cycles of case studies, the practical application of system dynamics modelling is evaluated. The role of system dynamics modelling in the management of coastal sand dunes, tourism ...

Assisting Stakeholder Decision Making Using System Dynamics Group Model-Building, Kristin den Exter, Alison Specht 2010 Southern Cross University

Assisting Stakeholder Decision Making Using System Dynamics Group Model-Building, Kristin Den Exter, Alison Specht

Dr Kristin den Exter

Stakeholder involvement in environmental management in Australia is increasingly participatory. A community-government partnership has been the central focus of the NSW program of water reforms since the inception of the Water Act 2000. Under the Act, it is the joint responsibility of the New South Wales Government and stakeholder-based Water Management Committees to develop Water Sharing Plans. Water Management Committees typically comprise government, environmental and agricultural representatives. This paper describes a System Dynamics group model-building workshop conducted with the Northern Rivers Water Management Committee. A role of the Committee was to determine the allocation of water between the water users ...

Three Dimensional Lattice Gravity As Supersymmetric Yang-Mills Theory, Simon Catterall 2010 Syracuse University

Three Dimensional Lattice Gravity As Supersymmetric Yang-Mills Theory, Simon Catterall

Physics

We argue that a certain twisted supersymmetric Yang-Mills theory in three dimensions with gauge group SU(2) possesses a set of topological observables whose expectation values can be computed in a related Chern Simons theory. This Chern Simons theory has been proposed as a definition of three dimensional Euclidean quantum gravity. Since the YM theory admits a discretization which preserves the values of topological observables we conjecture that it can be used as a non-perturbative definition of the quantum gravity theory.


Flat Zipper-Unfolding Pairs For Platonic Solids, Joseph O'Rourke 2010 Smith College

Flat Zipper-Unfolding Pairs For Platonic Solids, Joseph O'Rourke

Computer Science: Faculty Publications

We show that four of the five Platonic solids' surfaces may be cut open with a Hamiltonian path along edges and unfolded to a polygonal net each of which can "zipper-refold" to a flat doubly covered parallelogram, forming a rather compact representation of the surface. Thus these regular polyhedra have particular flat "zipper pairs." No such zipper pair exists for a dodecahedron, whose Hamiltonian unfoldings are "zip-rigid." This report is primarily an inventory of the possibilities, and raises more questions than it answers.


Building Information Objects, Morales Cristobal Velez 2010 Regis University

Building Information Objects, Morales Cristobal Velez

All Regis University Theses

In order to stay competitive in today' business environment, organizations must realize data is a key asset that needs to be exploited in order to achieve success. The usual approach to this is the implementation of data warehouses and business intelligence applications. However, most data warehouses are underutilized by decision makers and knowledge workers due to their lack of technical knowledge about what the data represents and how to map it to the semantic business concepts of the enterprise. Through the integration of Information Objects with a Business Intelligence Reporting tool end-users can acquire consolidated view corporate information. Information Objects ...


The Design And Synthesis Of Functionalized Porphyrins And Their Applications In Group Transfer Reactions, Medicine, And Materials, Kimberly Bliss Fields 2010 University of South Florida

The Design And Synthesis Of Functionalized Porphyrins And Their Applications In Group Transfer Reactions, Medicine, And Materials, Kimberly Bliss Fields

Graduate Theses and Dissertations

Porphyrins and their analogs are a class of chemically and biologically important compounds that have found a variety of applications in different fields such as catalysis, medicine, and materials. The physical, chemical, and biological dependence of the peripheral substituents of porphyrins on their properties has prompted great effort towards the synthesis of new porphyrins with different electronic, steric, and conformational environments. To this end, porphyrins have been prepared using a modular approach from bromo- and triflate synthons. These synthons underwent palladium-catalyzed cross-coupling with chiral amines, amides, alcohols, and boronic esters to create products that were tested for biological activity.

Metalloporphyrins ...


Bromide And Other Ions In The Snow, Firn Air, And Atmospheric Boundary Layer At Summit During Gshox, Jack E. Dibb, Luke D. Ziemba, J Luxford, P Beckman 2010 University of New Hampshire

Bromide And Other Ions In The Snow, Firn Air, And Atmospheric Boundary Layer At Summit During Gshox, Jack E. Dibb, Luke D. Ziemba, J Luxford, P Beckman

Earth Sciences Scholarship

Measurements of gas phase soluble bromide in the boundary layer and in firn air, and Br in aerosol and snow, were made at Summit, Greenland (72.5° N, 38.4° W, 3200 m a.s.l.) as part of a larger investigation into the influence of Br chemistry on HOx cycling. The soluble bromide measurements confirm that photochemical activation of Br in the snow causes release of active Br to the overlying air despite trace concentrations of Br in the snow (means 15 and 8 nmol Br kg−1 of snow in 2007 and 2008, respectively). Mixing ratios of ...
