Efficient Routing For Wireless Mesh Networks Using A Backup Path, Amir Esmailpour, Nidal Nasser, Jehad Al Dallal

Electrical & Computer Engineering and Computer Science Faculty Publications

Wireless Mesh Network (WMN) has a proven record in providing viable solutions for some of the fundamental issues in wireless networks such as capacity and range limitations. WMN infrastructure includes clusters of Mobile Ad-Hoc Networks (MANETs) connected through a fixed backbone of mesh routers. The mesh network can be constrained severely due to various reasons, which could result in performance degradation such as a drop in throughput or long delays. Solutions to this problem often focus on multipath or multichannel extensions to the existing ad- hoc routing protocols. In this paper, we propose a novel solution by introducing an alternative …

The Impact Of An Interdisciplinary Learning Community Course On Pseudoscientific Reasoning In First-Year Science Students, Timothy Franz, Kris H. Green

Psychology Faculty/Staff Publications

This case study examined the development and evaluation of an interdisciplinary first-year learning community designed to stimulate scientific reasoning and critical thinking. Designed to serve the needs of scholarship students majoring in mathematics and natural sciences, the six-credit learning community course was writing-intensive and emphasized general scientific reasoning and critical thinking skills. Success of the course was measured using a pre-test/post-test design that assessed students’ paranormal beliefs. Outcomes of the study indicated students’ paranormal beliefs were significantly lower at the end of the semester than at the beginning, which was used as a surrogate measure of scientific reasoning that was …

Eliminating Bus Stops: Evaluating Changes In Operations, Emissions And Coverage, Ranjay M. Shrestha, Edmund J. Zolnik

Journal of Public Transportation

Bus systems in the United States are unattractive to many potential riders because of their lack of efficiency, especially with regard to travel time. One of the reasons services are not more efficient has to do with the spacing of bus stops. After using a nearest facility algorithm with an 800 m walking distance threshold to identify eligible bus stops in the current bus system in the city of Fairfax, Virginia, the impacts of their elimination on operations, emissions, and coverage are estimated. Results indicate that eliminating some bus stops (about 40% of current stops) could improve travel times and …

Elementary Differential Equations With Boundary Value Problems, William F. Trench

Textbooks Collection

Elementary Differential Equations with Boundary Value Problems is written for students in science, engineering, and mathematics who have completed calculus through partial differentiation. If your syllabus includes Chapter 10 (Linear Systems of Differential Equations), your students should have some prepa- ration in linear algebra.

In writing this book I have been guided by the these principles:

An elementary text should be written so the student can read it with comprehension without too much pain. I have tried to put myself in the student’s place, and have chosen to err on the side of too much detail rather than not enough. …

Creating Safe Spaces: Bergson, Affirmation, And The Constitution Of Lgbtq Identity, Timothy Ross Johnston

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

The central claim of this dissertation is that the ability to feel comfortable, both in terms of your identity and in your fluid movement through the world, is the result of what I call affirmative feedback loops. When your environment affirms and reflects your identity back to you, you become comfortable with yourself and in that environment. This affirmation can be as direct as someone explicitly affirming you (for example, when you come out) or it can be as subtle and quotidian as being able to display photos of loved ones in your workspace. I argue that caring for other …

P12, A Novel Fibronectin Peptide, Promotes Cell Survival By Augmenting Pdgf-Bb Survival Signals, Jia Zhu

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Intensive research has demonstrated that extracellular matrix (ECM) and growth factor (GF) signaling collaborate at many different levels. Through integrins, ECM generates signals that enhance or suppress GF signaling. Some ECM activates GF receptor in the absence of GF. Furthermore, ECM contains growth factor binding-domains (GFBD) that can either sequester or present GF in ways that modify cell response. The ability of ECM to modulate GF signals has important implications in tissue engineering/regenerative medicine, and in devising therapies to treat acute and chronic wounds. Previously in our lab, a novel fibronectin peptide, P12, was shown to bind platelet-derived growth factor …

Error Reduction In Parameter Estimation With Case Studies In Risk Measurement And Portfolio Optimization, Xiaoping Zhou

Stony Brook Theses and Dissertations Collection, 2006-2020 (closed to submissions)

Parameter estimation is an important step in probabilistic and statistical modeling. Maximum likelihood estimators (MLE) are the classical parameter estimators. However, in the real world, for small samples or ill-posed problems maximum likelihood estimates may be difficult to find through direct numerical optimization, and are unstable and sensitive to outliers. In this dissertation, we study two popular problems in financial risk management and portfolio selection. The first problem is operational risk modeling. Data insufficiency and reporting threshold are two main difficulties in estimating the loss severity distributions in operational risk modeling. We investigate four methods including MLE, expectation-maximization (EM), penalized …

Electrotransfer Of Single-Stranded Or Double-Stranded Dna Induces Complete Regression Of Palpable B16.F10 Mouse Melanomas, Loree Heller, Vesba Todorovic, Maja Cemazar

Bioelectrics Publications

Enhanced tumor delivery of plasmid DNA with electric pulses in vivo has been confirmed in many preclinical models. Intratumor electrotransfer of plasmids encoding therapeutic molecules has reached Phase II clinical trials. In multiple preclinical studies, a reduction in tumor growth, increased survival or complete tumor regression have been observed in control groups in which vector or backbone plasmid DNA electrotransfer was performed. This study explores factors that could produce this antitumor effect. The specific electrotransfer pulse protocol employed significantly potentiated the regression. Tumor regression was observed after delivery of single-stranded or double-stranded DNA with or without CpG motifs in both …

St. Jude Medical: Pulmonary Edema Monitoring In Pacemakers And Icds, David Wei-Péng Chang

Master's Theses

Pulmonary edema occurs when fluid leaks from the pulmonary capillary network into the lung interstitium and alveoli. When the heart is not able to pump blood to the body efficiently, fluid can back up into the veins that take blood through the lungs to the left atrium. This then builds up the pressure in the blood vessels and fluid is pushed into the alveoli in the lungs. The fluid reduces normal oxygen movement through the lungs and can cause impaired gas exchange and respiratory failure. There are many causes of congestive heart failure that may lead to pulmonary edema such …

Active Learning Using Model-Eliciting Activities And Inquiry-Based Learning Activities In Dynamics, Jeffrey Phillip Georgette

Master's Theses

This thesis focuses on a year-long project of implementing active learning in undergraduate dynamics courses at Cal Poly San Luis Obispo from 2012-2013. The purpose is to increase conceptual understanding of critical dynamics concepts and to repair misconceptions of the students. Conceptual understanding in Dynamics is vital to understanding the big picture, building upon previous knowledge, and better understanding the behavior of engineering systems. Through various hands-on activities, students make predictions, test their conceptions, and solve real world problems. These active learning methods allow students to improve their learning of Dynamics concepts. Education research on active learning is present in …

Functional 3-D Cellulose & Nitrocellulose Paper-Based, Multiplex Diagnostic Platforms Without Coupling Agents, Mackenzie Elizabeth Tageson

Master's Theses

The purpose of this thesis was to demonstrate device functionality of 3-D paper-based, multiplex platforms, µPADs, without the use of coupling agents between layers. Previously, these platforms were fabricated with double-sided tape and cellulose powder to try to augment proper fluid routing, but difficulties with this method occurred. An acrylic housing unit with strategically placed pressure tabs was designed to aid horizontal and vertical fluid routing through the platform, thus eliminating the inconsistencies associated with coupling agents. Channel characterization studies, a COMSOL^TM simulation, and development time studies were performed to aid device design and demonstrate device functionality.

The implementation …

Design Of A Low Power Cargo Security Device Using A Micropower Ultra-Wideband Impulse Radar, Brian M. Wihl

Master's Theses

Each year, thousands of cargo containers are broken into during shipping, costing billions of dollars in lost and damaged goods. In addition to removing its contents, intruders can also add unwanted and dangerous materials to a container, posing a threat to National Security. The possibilities of cargo container break-ins require that the containers go through check points at which they are physically searched. These searches often require the opening of the container, unloading and inspecting all cargo, and then loading the container and resealing it. This is a long and costly process.

Because of the high costs of break-ins and …

Investigation Of Parameters Influencing Reverse Fault Rupture Propagation To The Ground Surface, Kevin V. Stanton

Master's Theses

Surface fault rupture poses a serious threat to infrastructure in many seismically active regions, but knowledge about the factors which control the likelihood of surface displacement is limited. Current probabilistic frameworks rely only on fault mechanism and moment magnitude to predict the probability of rupture to the ground surface. However, recent work has shown that there may be other parameters which also deserve consideration. For example, statistical analyses have demonstrated that variation in near surface material stiffness may significantly affect the probability of surface rupture over reverse faults. In addition, numerical investigations indicate that the rupture history of native soil …

Measuring The Counter/Assumption Model's Effect On Argumentation Quality, Evan D G Ovadia

Master's Theses

This thesis presents a new platform called See the Reason, built upon a tree- structured argumentation model called the Counter/Assumption model. In the Counter/Assumption model, a topic is posted first, then under that topic, reasons for and against, and for each reason, counterarguments, and for any counterargu- ment, more counterarguments. The model enables us to systematically determine whether a claim is “tentatively true” or “tentatively false,” in an effort to motivate people to make their side’s claims tentatively true and the opposing side’s claims tentatively false, thus encouraging conflict. Research suggests that debates with more conflict are better, so this …

Titanic: Consuming The Myths And Meanings Of An Ambiguous Brand, Stephen Brown, Pierre Mcdonagh, Clifford J. Shultz

School of Business: Faculty Publications and Other Works

Myths have come of age in consumer research. In the 22 years since Levy’s inaugural article, the literature has grown at an impressive rate. Yet important questions remain unanswered: What makes some myths especially meaningful to consumers? Why are certain consumer myths more prevalent and less perishable than others? This article argues that ambiguity is an influential factor. Using the RMS Titanic as an empirical exemplar, it unpacks the principal forms of myth-informed ambiguity surrounding “the unsinkable brand.” Predicated on William Empson’s hitherto unsung principles of literary criticism, the article posits that ambiguity in its multifaceted forms is integral to …

Dispersion Of A Solute In Hartmann Two-Fluid Flow Between Two Parallel Plates, J. P. Kumar, J. C. Umavathi

Applications and Applied Mathematics: An International Journal (AAM)

The paper presents an analytical solution for the dispersion of a solute in a conducting immiscible fluid flowing between two parallel plates in the presence of a transverse magnetic field. The fluids in both the regions are incompressible, electrically conducting and the transport properties are assumed to be constant. The channel walls are assumed to be electrically insulating. Separate solutions for each fluid are obtained and these solutions are matched at the interface using suitable matching conditions. The results are tabulated for various values of viscosity ratio, pressure gradient and Hartman number on the effective Taylor dispersion coefficient and volumetric …

Mathematical Modelling Of Blood Flow Through Catheterized Artery Under The Influence Of Body Acceleration With Slip Velocity, S. U. Siddiqui, Sapna Geeta

Applications and Applied Mathematics: An International Journal (AAM)

The flow of blood through stenosed catheterized artery with the effect of external body acceleration has been considered. The pulsatile flow behaviour of blood in an artery subjected to the pulsatile pressure gradient and slip velocity has been studied considering blood as a Newtonian fluid. The non-linear differential equations governing the fluid flow are solved using the perturbation method. The analytic expressions are derived for the velocity profile, flow rate, wall shear stress and effective viscosity. The computer codes are developed for the analysis of physiological parameters. The effects of various parameters on blood flow are discussed through graphs. It …

Exponentially Fitted Variants Of The Two-Step Adams-Bashforth Method For The Numerical Integration Of Initial Problems, Gurjinder Singh, V. Kanwar, Saurabh Bhatia

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, we propose new variants of the two-step Adams-Bashforth and the one-step Adams-Moulton methods for the numerical integration of ordinary differential equations (ODEs). The methods are constructed geometrically from an exponentially fitted osculating parabola. The accuracy and stability of the proposed variants is discussed and their applicability to some initial value problems is also considered. Numerical experiments demonstrate that the exponentially fitted variants of the two-step Adams-Bashforth and the one-step Adams-Moulton methods outperform the existing classical two-step Adams-Bashforth and one-step Adams- Moulton methods respectively.

Application Of The Optimal Homotopy Asymptotic Method For Solving The Cauchy Reaction-Diffusion Problem, H. Jafari, S. Gharbavy

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, the optimal homotopy asymptotic method is applied on the Cauchy reaction-diffusion problems to check the effectiveness and performance of the method. The obtained solutions show that the OHAM is more effective, simpler and easier than other methods. Moreover, this technique does not require any discretization or linearization and therefore it reduces significantly the numerical computations. The results reveal that the method is explicit.

Abstract Models Of Molecular Walkers, Oleg Semenov

Computer Science ETDs

Recent advances in single-molecule chemistry have led to designs for artificial multi-pedal walkers that follow tracks of chemicals. The walkers, called molecular spiders, consist of a rigid chemically inert body and several flexible enzymatic legs. The legs can reversibly bind to chemical substrates on a surface, and through their enzymatic action convert them to products. We study abstract models of molecular spiders to evaluate how efficiently they can perform two tasks: molecular transport of cargo over tracks and search for targets on finite surfaces. For the single-spider model our simulations show a transient behavior wherein certain spiders move superdiffusively over …

Eternal Recurrence In A Neo-Kantian Context, Michael S. Green

Faculty Publications

In this essay, I argue that someone who adopted a falsificationism of the sort that I have attributed to Nietzsche would be attracted to the doctrine of eternal recurrence. For Nietzsche, to think the becoming revealed through the senses means falsifying it through being. But the eternal recurrence offers the possibility of thinking becoming without falsification. I then argue that someone who held Nietzsche’s falsificationism would see in human agency a conflict between being and becoming similar to that in empirical judgment. In the light of this conflict only the eternal recurrence would offer the possibility of truly affirming life. …
