Supporting Multimedia Services Over A Token-Passing Bus Local Area Network., Hassan Soliman, T. El-Danaf

Mansoura Engineering Journal

Besides data transactions such as web surfing and e-commerce, the Internet today has been experiencing growth in audio and video streaming with the emergence of multimedia tools. However, the existing network infrastructure (e.g., Ethernet) only offers a single best effort class of service without any guarantees on delay variation, packet losses or available bandwidth. This can adversely impact the end-to-end performance of multimedia applications. Accordingly, a different class of Media Access Control (MAC) protocols must be used to support multimedia services over the existing Local Area Networks (LANs) without seeking to ehange it [3]. The token-passing bus was introduced to …

Road Development And Indigenous Hunting In Tanah Papua: Connecting The Facts For Future Wildlife Conservation Agendas, Freddy Pattiselanno, Andrew Krockenberger

Forest and Society

Road development is increasing worldwide. Generally, examples of road building in tropical countries demonstrate that road access can assist the fight against rural poverty, but such developments are also linked to deforestation, pollution, invasions of exotic species, and environmental degradation. For Papua and West Papua provinces (Tanah Papua) in Indonesia, the development of the provincial road network is intended to improve the rural economy, aiming to alleviate poverty within isolated rural areas. However, road development can pose particularly challenging problems to rural and Indigenous communities. Poorly planned roads can be devastating when they provide easy access to illegal hunting that …

Effect Of Temperature On Early‐Age Properties Of Self‐Consolidating Concrete Equivalent Mortar, Nima Farzadnia, Jing Pan, Kamal Khayat, Eric Wirquin

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

In this study, the effect of ambient temperature during casting on fresh properties, hydration kinetics, and early‐age compressive strength of self-consolidating concrete (SCC) was evaluated. Concrete equivalent mortars (CEMs) with water‐to‐binder ratios of 0.41 and 0.45 were cast based on SCC mixture designs for building and infrastructure construction and precast applications. The CEMs were prepared at temperatures ranging from 8 to 36°C. Superplasticizer (SP) and air‐entraining agent (AEA) demand were evaluated for the CEM mixtures made with different supplementary cementing material (SCM) and limestone filler types. Test results showed that the ambient temperature can significantly affect the SP and AEA …

Towards A Reduced Phase Space Quantization In Loop Quantum Cosmology With An Inflationary Potential, Kristina Giesel, Bao Fei Li, Parampreet Singh

Faculty Publications

We explore a reduced phase space quantization of loop quantum cosmology (LQC) for a spatially flat Friedmann-Lemaître-Robertson-Walker (FLRW) universe filled with reference fields and an inflaton field in a Starobinsky inflationary potential. We consider three separate cases in which the reference fields are taken to be the Gaussian dust, the Brown-Kuchař dust, and massless Klein-Gordon scalar reference fields respectively. This is a "two-fluid"model in which reference fields act as global clocks providing a physical time in an inflationary spacetime, and allow bypassing various technical hurdles in conventional quantum cosmological models. The reduced phase space is obtained in terms of the …

The Role Of Exposure To Communication Channels, Institutional Trust And Moral Norm In Predicting Pm2.5 Risk-Reduction Intention In China: A Study Of The Theory Of Planned Behavior., Tong Lin

Theses - ALL

Understanding and encouraging people to perform PM2.5 risk-reduction behaviors is essential to reduce the health risks caused by PM2.5 and to promote a healthy lifestyle. This study aims to predict the effects of psychological factors (attitude, perceived behavioral control, subjective norm and moral norm) on individual’s PM2.5 risk-reduction intention. It also looks into how contextual factors (exposure to communication channels and institutional trust) can influence behavioral intention and make contributions to the predicting powers of the theory of planned behavior. To achieve this goal, I analyze the secondary survey data that randomly selected residents living in three regions known for …

Modeling Intra-Annual Variation In Coral Extension Rate Using Multiproxy Geochemical Records From Pacific Corals, Jessie Mccraw

Theses - ALL

The relationship between coral growth and environmental parameters is not straightforward, and few studies have explored intra-annual changes in extension rate. Variations in the magnitude and timing of intra-annual extension could be influenced by various environmental parameters such as sea surface temperature (SST), light and nutrient availability, turbidity or salinity stress, as well as by inter-annual climate variations such as the El Niño-Southern Oscillation (ENSO). In this study we use SST proxy data from Porites spp. corals to model intra-annual growth using an iterative numerical model comparing growth and temperature sine functions to measured Sr/Ca data to find the best …

A Tale Of Two Nations’ Histories The Application Of Literary Fairy Tales As A Firsthand Account Of History, Nicholas Gottlob

Honors College Theses

Fairy tales are often thought to be solely for children as a means of education and entertainment. The literary fairy tale provided a medium that allowed authors to express their opinions under the guise of a story. This has not always been the case as literary fairy tales have been utilized as political instruments by authors and intended for a highly educated audience. Using fairy tales as a facade provided protection for authors, as outright criticisms against those in power usually resulted in dire consequences such as imprisonment or even death for the objector. The literary fairy tale provided a …

Nonparametric Identification And Estimation Of Stochastic Frontier Models, Jun Cai

Dissertations - ALL

This dissertation studies nonparametric identication and estimation of stochastic frontiermodels. It is composed of three chapters. The rst chapter investigates the identication and estimation of a cross sectional stochastic frontier model with Laplacian errors and unknown variance, which is built on a nonparametric density deconvolution strategy. Chapter two studies a zero-ineciency stochastic frontier model utilizing a penalized sieve estimator, which allows flexible function forms and arbitrary distributions of ineciency. The third chapter explores identication and estimation of a nonparametric panel stochastic frontier model based on Kotlarski's Lemma and moments derived from conditional characteristic functions.

A Model Of Scaffolded Encoding, Yanxiu Chen

Dissertations - ALL

Repetitions are ubiquitous and are the foundation of episodic memory. As we investigate episodic memory in a laboratory setting and with, usually, a study-test design, we have inaccurately assumed encoding happens only at study and retrieval happens only at test. However, it’s entirely possible that encoding and retrieval happen simultaneously at both study, with explicit repetition, and test, with implicit repetition. The fallacy that encoding and retrieval are separate processes coincides with the unsatisfactory status of memory process model: there is no unified memory model. Most models of memory are models of retrieval tasks. Facing these two challenges, we proposed …

Examining The Mediational Role Of Writing Motivation In The Writing Development Of Elementary-Aged Students, Brittany Eggleston

Dissertations - ALL

Motivational variables, such as writing self-efficacy and writing attitudes, are not emphasized in writing frameworks for developing writers. The purpose of this research study was to extend the research literature on elementary-aged students’ writing development by examining the potential mediational role of writing self-efficacy and writing attitudes between foundational academic skills (e.g., handwriting, spelling, and executive functioning/working memory skills) and written performance. Measures of spelling, handwriting, executive function/working memory skills, writing self-efficacy, writing attitudes, and written expression were administered to 140 third-grade and fifth-grade students. In this correlational research study, a parallel mediational analysis was conducted to examine whether writing …

Neuromodulation By Endogenous Interlukin-1Β In Hippocampus Of The Murine Brain: Regulation Of Neuronal Excitation, Spandita Seouli Dutta

Dissertations - ALL

The pro-inflammatory cytokine, Interleukin-1β (IL-1β), is well known for its ability to initiate and propagate inflammatory responses at sites of infection and tissue injury. Paradoxically at odds with this classic view, it is now clear that IL-1β signaling modulates a number of physiological functions in the central nervous system. In this regard, IL-1β is involved in sleep and body fluid regulation in the basal forebrain and hypothalamus, respectively, and plasticity changes that underlie cognition in the hippocampus. Evidence from a previous study in my laboratory further suggests that IL-1β regulates the innate seizure threshold, which arguably is a reflection of …

Discrete-Time Stable Geometric Controller And Observer Designs For Unmanned Vehicles, Reza Hamrah

Dissertations - ALL

In the first part of this dissertation, we consider tracking control of underactuated systems on the tangent bundle of the six-dimensional Lie group of rigid body motions, SE(3). We formulate both asymptotically and finite-time stable tracking control schemes for underactuated rigid bodies that have one translational and three rotational degrees of freedom actuated, in discrete time. Rigorous stability analyses of the tracking control schemes presented here guarantee the nonlinear stability of these schemes. The proposed schemes here are developed in discrete time as it is more convenient for onboard computer implementation and ensures stability irrespective of the sampling period. A …

Natural And Synthetic Ligand-Binding Induce Different Pilin Assemblies In Vitro And Control P. Aeruginosa Bioactivities In Vivo, And Development Of Bacterial-Motility Enabled Binding Assays, Arizza Chiara Siwa Ibañez

Dissertations - ALL

Proteins found on bacterial cells surfaces are capable of sensing and transducing signals from the environment to elicit a biological response. Fibrous appendages formed by assembly of pilin proteins on P. aeruginosa are surface proteins that are necessary for host colonization, adhesion on abiotic surfaces, controlling motilities, formation of biofilm, horizontal gene transfer and virulence production of the bacterium. Upon contact with stimuli, pili appendages extend and retract on the cell surface, driven by the assembly and disassembly of pili at inner membrane of the bacteria cells. The dynamic response of this protein assembly is likely caused by a conformational …

Reinforcement Learning For Mobile Robot Collision Avoidance In Navigation Tasks, Zilong Jiao

Dissertations - ALL

Collision avoidance is fundamental for mobile robot navigation. In general, its solutions include: {\it map-based} and {\it mapless approaches.} In the map-based approach, robots pre-plan collision-free paths based on an environment map and follow their paths during navigation. On the other hand, the mapless approach requires robots to avoid collisions without referencing to an environment map. This thesis first studies the map-based approach for multiple robots to collectively build environment maps. In this study, a robot following a pre-planned path may encounter unexpected obstacles, such as other moving robots and obstacles inaccurately presented on an environment map. This motivates us …

Wavelength-resolved extinction spectra of urban grime samples were also analyzed to improve our understanding of urban grime’s role in photochemistry. The research showed that the grime from the American cities was similar in composition to previous studies conducted in Europe and Canada, but …

4d Printing Shape Memory Polymers For Biomedical Applications, Kathleen Pieri

Dissertations - ALL

The development of 3D printing techniques using shape-memory polymers (SMPs) hascreated potentials for creating dynamic, three-dimensional structures that can be produced rapidly and be customized for specific and complex architectures. These qualities have made 3D printing a popular fabrication method for future SMP parts and devices. While important information about is known about the effects of printing parameters on 3D printed SMPs, there remains a gap in the understanding of these parameters on fundamental shape memory properties. Understanding the shape memory behavior of the SMPs post-printing can implicate potential advantages or weaknesses in using these materials in biomedical applications. Furthermore, …
