Urban Bus Services In Developing Countries And Countries In Transition: A Framework For Regulatory And Institutional Developments, Brendan Finn, Corinne Mulley

Journal of Public Transportation

Urban passenger transport has experienced major change in many developing countries in Africa, Asia, and the Middle East, as well as in countries of political and/or economic transition in the Commonwealth of Independent States (CIS) and China. Such changes have included planned market opening to private operators and new entrants; unplanned market opening by the entry of unlicensed operators; privatization and other changes to the ownership base of large public-sector transport companies; emergence of large-scale minibus and paratransit; and national and urban policies and programs to upgrade the transport supply and quality. This paper presents a framework to understand regulatory …

New Test Set For Video Quality Benchmarking, Joaquin Raventos

Electronic Theses and Dissertations

A new test set design and benchmarking approach (US Patent pending) allows a "standard observer" to assess the end-to-end image quality characteristics of video imaging systems operating in day time or low-light conditions.

It uses randomized targets based on extensive application of Photometry, Geometrical Optics, and Digital Media.

The benchmarking takes into account the target’s contrast sensitivity, its color characteristics, and several aspects of human vision such as visual acuity and dynamic response. The standard observer is part of the "extended video imaging system" (EVIS).

The new test set allows image quality benchmarking by a panel of standard observers at …

Implementation Of Medicinal Leech Preparation To Investigate The Connection Between The Motor Neuron And Muscle Fiber Via Sharp Electrode Electrophysiology, Chandra Nikole Miller

Master's Theses

There are forty registered organophosphates in the United States and they range from pesticides and insecticides to nerve agents or neurotoxins such as sarin. Organophosphates (OP’s) have been used in chemical warfare for years and tend to lead to death due to an attack on the nervous system. Chemical assays and mass microscopy have been used to assess the concentration of OP’s in the environment, but both methods require the body to metabolize the OP first, which can be detrimental to the victim. It is crucial to come up with a method to investigate and detect these neurotoxins without causing …

Digitally Controlled, Modular Electronic Load, Jason L. March

Master's Theses

This project entails the design and development of a digitally controlled, modular electronic load. The proposed load is unique from existing designs because it has the added ability to increase its maximum current level by adding identical modules in parallel. Each module is designed to sink a maximum of 5A at 60V but more modules allow for more current. The cost and simplicity of the design are considered such that it can be reproduced in-house to replace, whenever possible, the resistor box for load testing of any analog circuits but more specifically power electronic circuits.

The design process as well …

Impact Of Collateral Enlargement On Smooth Muscle Phenotype, Alexander Jerome Bynum

Master's Theses

Peripheral Artery Disease is a very serious disease characterized by an arterial occlusion due to atherosclerotic plaques. In response to an arterial occlusion, arteriogenesis occurs, causing smooth muscle cells to transition from a contractile to synthetic state. Also following an arterial occlusion, functional impairment was seen in the collateral circuit. An immunofluorescence protocol was developed in order to assess the impact of collateral enlargement (arteriogenesis) on smooth muscle phenotype at various time points. Smooth muscle α-actin was used to mark all smooth muscle cells, Ki-67 was used to label proliferating smooth muscle cells, and a fluorescent nuclear stain was used …

Experimental Investigation Of A 2-D Air Augmented Rocket: Effects Of Nozzle Lip Thickness On Rocket Mixing And Entrainment, Trevor Allen Montre

Master's Theses

Cold-flow tests were performed using a simulated Air Augmented Rocket (AAR) operating as a mixer-ejector in order to investigate the effects of varied primary nozzle lip thickness on mixing and entrainment. The simulated primary rocket ejector was supplied with nitrogen at a maximum chamber stagnation pressure of 1712 psi, and maximum flow rate of 1.67 lb_m/s. Secondary air was entrained from a plenum, producing pressures as low as 6.8 psi and yielding maximum stagnation pressure ratios as high as 160. The primary ejector nozzles each had an area ratio of approximately 20, yielding average primary exit Mach numbers …

Adhesion And Durability Of Coatings On Polypropylene Exterior Sidings, Logan Riekio Stark

Master's Theses

Plastics have become a universal material for use in a myriad of commercial and consumer products. One such product, exterior siding, is the focus of this project. Although siding products were originally made from wood, vinyl siding, which offered superior performance, was introduced in the 1950’s. More recently, polypropylene (PP) siding has been introduced; PP provides a stronger product, which allows for deeper patterns and better edge detailing. PP siding, compared to traditional wood siding, doesn’t warp, crack, or degrade as easily with extended exposure to the elements, and is cheaper to maintain. However, even plastic siding must be coated. …

Freight Truck Traffic Associated With The Port Of Oakland: A Case Study Of Roadway Impacts, James Hinkamp

Master's Theses

The Port of Oakland (“Port”) is the 5th largest container seaport by volume in the U.S. and the largest in Northern California. Maritime shipping activity at the Port exceeds 2 million import and export twenty-foot equivalent unit (TEU) containers annually. Containers may be full or empty, but nonetheless typically require hinterland shipment and intermodal transfer between maritime and land-based freight distribution systems. The freight trucking mode (“drayage”) handles approximately 80% of all TEU throughput at the Port, thus constituting the majority of landside Port traffic. The Port is also situated adjacent to dense urban development thereby exacting certain external impacts. …

2012 Nebraska Crop Budgets, Roger K. Wilson

Cornhusker Economics

Overall, average projected cash costs per unit of production for 2012 are almost 15 percent higher than the 2011 projections made in April.

Some of this increase is due to a higher labor wage. Twenty dollars per hour was used as the wage rate in 2012, compared to $12 per hour in 2011. Wage rates vary substantially from one producer to the next, and there is no suitable index for determining a representative wage. It is not likely that actual wages paid increased that much from one year to the next, so this change represents an adjustment upwards as well …

Mathematical Modeling Of Peristaltic Flow Of Chyme In Small Intestine, Daniel N. Riahi, Ranadhir Roy

Applications and Applied Mathematics: An International Journal (AAM)

Mathematical models based on axisymmetric Newtonian incompressible fluid flow are studied for the peristaltic flow of chyme in the small intestines, which is an axisymmetric cylindrical tube. The flow is modeled more realistically modeled by assuming that the peristaltic rush wave is a non-periodic mode composed of two sinusoidal waves of different wavelengths, which propagate at the same speed along the outer boundary of the tube. Both cases of flow in a tube and in an annulus that are modeled and investigated in the present paper correspond respectively to the cases of flow of chyme in the small intestine in …

Peristaltic Induced Flow Of A Two-Layered Suspension In Non-Uniform Channel, Amit Medhavi, Dharmendra Singh, Ajay S. Yadav, Ramesh S. Gautam

Applications and Applied Mathematics: An International Journal (AAM)

Peristaltic transport of a two-layered particulate suspension in a non-uniform channel has been investigated. The coupled differential equations for both the fluid and the particle phases in the central as well as in the peripheral layers have been solved and the expression for the flow rate, the pressure rise and the friction force has been derived. The results obtained are discussed both qualitatively and quantitatively in brief. The significance of the particle concentration as well as the peripheral layer has been well explained.

Reflection Of Waves In Transversely Isotropic Thermoelastic Solid, Raj R. Gupta

Introduction In last three decades, non-classical theories involving finite speed of heat transportation in elastic solids have been …

Nonlinear Ordinary Differential Equations In Fluid Dynamics, John D. Ramshaw

Physics Faculty Publications and Presentations

The equivalence between nonlinear ordinary differential equations (ODEs) and linear partial differential equations (PDEs) was recently revisited by Smith, who used the equivalence to transform the ODEs of Newtonian dynamics into equivalent PDEs, from which analytical solutions to several simple dynamical problems were derived. We show how this equivalence can be used to derive a variety of exact solutions to the PDEs describing advection in fluid dynamics in terms of solutions to the equivalent ODEs for the trajectories of Lagrangian fluid particles. The PDEs that we consider describe the time evolution of non-diffusive scalars, conserved densities, and Lagrangian surfaces advected …

Wikipedia, Ipods, And Chickens : An Active Learning Exercise To Teach Evaluation Of Information., Latisha Reynolds, Anna Marie Johnson

Faculty and Staff Scholarship

Librarians at the University of Louisville developed an evaluation of information exercise that is completely interactive. Students learn evaluation skills by participating in a small-group exercise, after which, the groups teach their classmates what they have learned.

Each small-group is assigned a different publication to evaluate such as a book, a website, a scholarly article, magazine or newspaper. They also have questions to answer in order to evaluate each source. After they evaluate the sources, each group chooses a student to present the information in front of the class.

The librarian acts as a facilitator to guide the students and …

Spatiotemporal Computed Tomography Of Dynamic Processes, Anders Kaestner, Beat Münch, Pavel Trtlk, Les Butler

Faculty Publications

Modern computed tomography (CT) equipment allowing fast 3-D imaging also makes it possible to monitor dynamic processes by 4-D Imaging. Because the acquisition time of various 3-D-CT systems is still in the range of at least milliseconds or even hours, depending on the detector system and the source, the balance of the desired temporal and spatial resolution must be adjusted. Furthermore, motion artifacts will occur, especially at high spatial resolution and longer measuring times. We propose two approaches based on nonsequential projection angle sequences allowing a convenient postacquisition balance of temporal and spatial resolution. Both strategies are compatible with existing …

Site-Specific Proteolytic Cleavage Of The Amino Terminus Of Herpes Simplex Virus Glycoprotein K On Virion Particles Inhibits Virus Entry, Nithya Jambunathan, Sona Chowdhury, Ramesh Subramanian, Vladimir N. Chouljenko, Jason D. Walker, Konstantin G. Kousoulas

Faculty Publications

Herpes simplex virus 1 (HSV-1) glycoprotein K (gK) is expressed on virions and functions in entry, inasmuch as HSV-1(KOS) virions devoid of gK enter cells substantially slower than is the case for the parental KOS virus (T. P. Foster, G. V. Rybachuk, and K. G. Kousoulas, J. Virol. 75:12431-12438, 2001). Deletion of the amino-terminal 68-amino-acid (aa) portion of gK caused a reduction in efficiency and kinetics of virus entry similar to that of the gK-null virus in comparison to the HSV-1(F) parental virus. The UL20 membrane protein and gK were readily detected on double-gradient-purified virion preparations. Immuno-electron microscopy confirmed the …

Network Covert Channels On The Android Platform, Wade Chester Gasior

Masters Theses and Doctoral Dissertations

Network covert channels are used to exfiltrate information from a secured environment in a way that is extremely difficult to detect or prevent. These secret channels have been identified as an important security threat to governments and the private sector, and several research efforts have focused on the design, detection, and prevention of such channels in enterprise-type environments. Mobile devices have become a ubiquitous computing platform, and are storing or have access to an increasingly large amount of sensitive information. As such, these devices have become prime targets of attackers who desire access to this information. In this work, we …

This application was implemented using a model protection system that was designed to simulate actual relaying operations performed in the electric power system. The implemented application provided automated testing functionality that performed phase instantaneous over-current protection and phase distance protection testing. The modularity of the implemented software application provides the framework for the automated testing of a relay’s complete protection abilities. Automated testing using this application was performed by driving the outputs of an Omicron CMC …

Social Networks And The Desire To Save Face: A Case From Singapore, Michael A. Netzley, Akanksha Rath

Research Collection Lee Kong Chian School Of Business

For five years, corporate communication undergraduates have maintained a wiki as a final course and community service project. Using Web 2.0 platforms to crowdsource and curate content, they learn to employ online communications for work purposes. When the course was launched in 2007, the dominant social media narrative invited educators to embrace a technological optimism with sub-themes of open communication, sharing, and co-creation. By 2011, student feedback had compelled the instructor to consider the limits of technological optimism and revise the course. Specifically, Singaporean students have displayed a need to save face online, which has led to a localized teaching …
