A Stochastic Segmentation Model For Recurrent Copy Number Alterations In Grouped Array-Cgh Data, Ying Cai

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

With the recent advances in high resolution microarrays and next generation sequencing, DNA copy number can now be profiled in a high throughput global manner. This has enabled the systematic study of DNA copy number alterations in tumors, as well as the profiling of inherited population-wide copy number variants. Studies of DNA copy number usually involve many samples that fall into different groups, e.g. tumor subtype or ethnic group. It is often of interest to find recurrent alterations within each group. We develop a stochastic segmentation model for detecting recurrent DNA copy number alterations in grouped array-CGH data. In our …

Synthesis And Structures Of New Three-Dimensional Copper Metal-Organic Frameworks, Nitin Kumar Pally

Masters Theses & Specialist Projects

Metal-organic frameworks (MOFs) are crystalline materials with metal ions covalently bonded to organic ligands. The ligands act as spacers often creating a porous structure with very high pore volume and surface area. MOFs are known for their robust structures, high porosity, and different chemical functionalities and are considered for applications in adsorptions, separations, catalysis and gas storage. This work focuses on the synthesis of new MOFs using copper compounds. Different types of carboxylate ligands were used for the synthesis. Two new copper-organic frameworks, [Cu₃(pyz)(btc)] (1), and [(Cu₃(btc))•xH₂O] (2) (btc= benzene-1,3,5-tricarboxylate, pyz= pyrazine) have been …

Simulation-Based Regression Models To Estimate Bus Routes And Network Travel Times, Yaser E. Hawas

Journal of Public Transportation

This paper presents an approach to estimate bus route and network travel times using micro-simulation. This can be used in predicting the effectiveness of bus route designs using some network traffic measures or indicators. The used indicators are average network traffic intensity, posted speeds, route length, frequency of bus operation, and average passenger loadings (boarding and alighting). Regression models are calibrated to predict both route and overall network travel times. The prediction errors of these models were investigated and analyzed, and regression models were validated. Results indicated the validity of the calibrated regression models. Conclusions are made on how the …

Ridership And Revenue Implications Of Free Fares For Seniors In Northeastern Illinois, Paul Metaxatos

Journal of Public Transportation

This paper reports on the ridership and revenue impacts for transit providers of a short-lived Seniors Free Ride Program in the Chicago metropolitan area. The discussion presents survey-free and survey-based approaches specifically developed to capture such effects during the program implementation. The analysis shows that instituting a free fare policy for seniors expectedly increased the demand for and associated costs of providing the service. In particular, the program had attracted approximately 75 percent additional senior rides at an associated cost of between $26.1 and $78.6 million. The Illinois legislature modified the program in 2011 to run as a means-tested program …

Humor As A Tool For Addressing The Affective Domain During Information Literacy Instruction, Joshua Vossler, John Watts

LOEX Conference Proceedings 2011

Gaining and maintaining student attention during information literacy instruction can be a challenge. To address this challenge, entertainment value, as well as instructional efficacy, ought to be factored into assessment and design of instructional materials. Information literacy instruction should be as much about building bridges with students as it is about imparting useful information and skills. Entertaining while educating (edutaining), promotes student attention and helps build a positive learning environment. In this interactive session, attendees will participate in a practical approach to producing creative and entertaining content for information literacy instruction.

Demonstrating the production of digital objects will help promote digital wisdom in the classroom by making the process transparent. To this end, we will demonstrate the following:

- A LibGuide that is interactive, welcoming, personal, and helpful and that will focus on how to teach students or faculty about video editing. …

Funds Of Knowledge And Literacies In Latino/A Youths' Community-Based Engineering Design Work, Amy Wilson-Lopez, Joel Alejandro Mejia, Indhira María Hasbún, Daniel L. Householder, Chris Hailey

Teacher Education and Leadership Faculty Publications

STEM fields in the US continue to be dominated by people whose cultural backgrounds are White, English-speaking, and middle class (National Academy of Engineering and National Research Council, 2009). Many reasons have been offered to explain this phenomenon: Students’ backgrounds may include worldviews, beliefs, and communicative practices that do not cohere with those practiced in STEM classrooms (Aikenhead & Jegede, 1999; Lee, 1999); instructional materials may present STEM fields as a-cultural, decontextualized practices with no evident connection to students’ lives and communities, such as the routine completion of numerical exercises (O’Halloran, 2005); students’ identities—shaped in part by their desired life …

Brave New World Reloaded: Advocating For Basic Constitutional Search Protections To Apply To Cell Phones From Eavesdropping And Tracking By Government And Corporate Entities, Mark Berrios-Ayala

HIM 1990-2015

Imagine a world where someone’s personal information is constantly compromised, where federal government entities AKA Big Brother always knows what anyone is Googling, who an individual is texting, and their emoticons on Twitter. Government entities have been doing this for years; they never cared if they were breaking the law or their moral compass of human dignity. Every day the Federal government blatantly siphons data with programs from the original ECHELON to the new series like PRISM and Xkeyscore so they can keep their tabs on issues that are none of their business; namely, the personal lives of millions.

Simultaneous Energy Harvesting And Vibration Control Of Tall Buildings Using Electricity-Generating Tuned Mass Dampers, Xiudong Tang

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

Tall buildings, slender towers and long-span bridges are very susceptible to dynamic load from wind, and consequently vibrations are persistent in these civil structures during daily operation, which are serious concerns to both engineers and architects for the protection of the structure safety and occupant comfort. In order to mitigate the vibration, different approaches have been proposed, among which Tuned Mass Dampers (TMDs) are one of the most preferable and have been widely used in practice. Instead of dissipating the vibration energy into heat waste via the viscous damping element, we proposed an innovative structural vibration control method in this …

Task Driven Geometric Synthesis Of Planar And Spherical Mechanisms, Ping Zhao

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

This dissertation deals with the classical problem of designing planar and spherical mechanisms for motion generation from a new, task driven perspective. The field of mechanism synthesis dates back to the days of Industrial Revolution and the traditional approach to the problem involves two major steps: type synthesis and dimensional synthesis, where the former deals with the selection of the joint types as well as the topology of a mechanism, and the latter aims at finding the link dimensions of the mechanism. The problem of dimensional synthesis lends itself naturally to mathematical treatment and thus became a highly developed field. …

Teaching Geophysics With A Vertical-Component Seismometer, Kasper Van Wijk, Ted Channel, Karen Viskupic, Martin L. Smith

Geosciences Faculty Publications and Presentations

Earthquakes are some of the more dramatic expressions of the dynamics of our planet. The sudden release of stress built up slowly by tectonic or volcanic processes often has far-reaching consequences, and can be measured (in classrooms) around the world. This is one reason why designing and building seismometers has been a popular activity,^1,2 and why different versions of “Seismometer in Schools” projects thrive in the United States, Australia, and Europe. We present a cheap, robust, and easy-to-build seismometer—called the TC1 —to measure seismic displacements in the vertical direction. Its components are easy to obtain and assemble, yet the …

An Argument And Plan For Promoting The Teaching And Learning Of Neglected Tropical Diseases, Kevin M. Bonney

Publications and Research

Neglected tropical diseases constitute a significant public health burden, affecting over one billion people globally, yet this group of diseases is underrepresented in the appropriation of both monetary and intellectual capital for developing improved therapies and public health campaigns. The topic of neglected tropical diseases has been similarly marginalized in the biology classrooms of our nation’s high schools and colleges, despite offering an opportunity to teach and learn about a diverse area of microbiology with far-reaching public health, social, and economic implications. Discussed herein is an argument for increasing the representation of neglected tropical diseases in microbiology education as a …

Speech Enhancement By Exploiting The Baseband Phase Structure Of Voiced Speech For Effective Non-Stationary Noise Estimation, Sanjay Patil

All Theses

Speech enhancement is one of the most important and challenging issues in the speech communication and signal processing field. It aims to minimize the effect of additive noise on the quality and intelligibility of the speech signal. Speech quality is the measure of noise remaining after the processing on the speech signal and of how pleasant the resulting speech sounds, while intelligibility refers to the accuracy of understanding speech. Speech enhancement algorithms are designed to remove the additive noise with minimum speech distortion.The task of speech enhancement is challenging due to lack of knowledge about the corrupting noise. Hence, the …

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 …

Physics Faculty Research & Creative Works

We measure the sum of the neutrino particle masses using the three-dimensional galaxy power spectrum of the Sloan Digital Sky Survey III (SDSS-III) Baryon Oscillation Spectroscopic Survey Data Release 9 the constant MASS (CMASS) galaxy sample. Combined with the cosmic microwave background, supernova and additional baryonic acoustic oscillation data, we find upper 95 per cent confidence limits (CL) of the neutrino mass ∑m_ν < 0.340 eV within a flat Λ cold dark matter (ΛCDM) background, and ∑m_ν< 0.821 eV, assuming a more general background cosmological model. The number of neutrino species is measured to be N_eff = 4.308 ± 0.794 and 4.032+0.870 _-0.894 for these two cases, respectively. We study and quantify the effect of several factors on the neutrino measurements, including the galaxy power spectrum bias model, the …

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 …

Teacher Evaluations And Merit Pay: An Uneasy Mix, David Alan Dolph

Educational Leadership Faculty Publications

Teacher evaluations are undergoing significant changes in response to demands for school reform and higher accountability. States are now including value-added data in teacher evaluations, experimenting with merit pay based on evaluations, or both. Colorado, Florida, New Jersey, New York, and Texas are but a few states that have altered the way teachers are evaluated or that are incorporating value-added data.

Changes in evaluation practice will likely mean significant modifications in how building-level administrators evaluate teachers. Moreover, approaches to teacher salary systems are just as likely to be altered if merit pay is introduced. School business officials (SBOs) are typically …

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. …
