An Architectural Design And Evaluation Of An Affective Tutoring System For Novice Programmers, Hua Leong Fwa

Research Collection School Of Computing and Information Systems

Affect is prevalent in learning and it influences students’ learning achievement. This paper details the design and evaluation of an Affective Tutoring System (ATS) that tutors student in computer programming. Although most ATSs are purpose built for a specific domain, making adaptation to another domain difficult, this ATS is architected for adaptability and extensibility. This study also addresses a lack of research exploring the theories and methods of integrating affect and learning within the learning process by proposing methods of regulating the negative affect of students. Both quantitative and qualitative techniques were used for evaluation of the effectiveness of the …

Deep Air Learning: Interpolation, Prediction, And Feature Analysis Of Fine-Grained Air Quality, Zhongang Qi, Tianchun Wang, Guojie Song, Weisong Hu, Xi Li, Zhongfei Mark Zhang

Research Collection School Of Computing and Information Systems

The interpolation, prediction, and feature analysis of fine-gained air quality are three important topics in the area of urban air computing. The solutions to these topics can provide extremely useful information to support air pollution control, and consequently generate great societal and technical impacts. Most of the existing work solves the three problems separately by different models. In this paper, we propose a general and effective approach to solve the three problems in one model called the Deep Air Learning (DAL). The main idea of DAL lies in embedding feature selection and semi-supervised learning in different layers of the deep …

Using Smart Card Data To Model Commuters’ Responses Upon Unexpected Train Delays, Xiancai Tian, Baihua Zheng

Research Collection School Of Computing and Information Systems

The mass rapid transit (MRT) network is playing an increasingly important role in Singapore's transit network, thanks to its advantages of higher capacity and faster speed. Unfortunately, due to aging infrastructure, increasing demand, and other reasons like adverse weather condition, commuters in Singapore recently have been facing increasing unexpected train delays (UTDs), which has become a source of frustration for both commuters and operators. Most, if not all, existing works on delay management do not consider commuters' behavior. We dedicate this paper to the study of commuters' behavior during UTDs. We adopt a data-driven approach to analyzing the six-month' real …

Privacy-Preserving Remote User Authentication With K-Times Untraceability, Yangguang Tian, Yingjiu Li, Binanda Sengupta, Robert H. Deng, Albert Ching, Weiwei Liu

Research Collection School Of Computing and Information Systems

Remote user authentication has found numerous real-world applications, especially in a user-server model. In this work, we introduce the notion of anonymous remote user authentication with k-times untraceability (k-RUA) for a given parameter k, where authorized users authenticate themselves to an authority (typically a server) in an anonymous and k-times untraceable manner. We define the formal security models for a generic k-RUA construction that guarantees user authenticity, anonymity and user privacy. We provide a concrete instantiation of k-RUA having the following properties: (1) a third party cannot impersonate an authorized user by producing valid transcripts for the user while conversing …

Towards Scalable Characterization Of Noisy, Intermediate-Scale Quantum Information Processors, Travis Luke Scholten

Physics & Astronomy ETDs

In recent years, quantum information processors (QIPs) have grown from one or two qubits to tens of qubits. As a result, characterizing QIPs – measuring how well they work, and how they fail – has become much more challenging. The obstacles to characterizing today’s QIPs will grow even more difficult as QIPs grow from tens of qubits to hundreds, and enter what has been called the “noisy, intermediate-scale quantum” (NISQ) era. This thesis develops methods based on advanced statistics and machine learning algorithms to address the difficulties of “quantum character- ization, validation, and verification” (QCVV) of NISQ processors. In the …

In Chapters 2 and 3, I examine how female BMI varies by race and ethnicity. In Chapter 4, I study the effect of food deserts on BMI and obesity for both males and females.

In Chapter 2, I use Bayesian Model Averaging (BMA) to examine the factors that influence female BMI for the adult working age population. Results indicate 12 of the 40 covariates are strongly …

Preprocess-Then-Ntt Technique And Its Applications To Kyber And Newhope, Shuai Zhou, Haiyang Xue, Daode Zhang, Kunpeng Wang, Xianhui Lu, Bao Li, Jingnan He

Research Collection School Of Computing and Information Systems

The Number Theoretic Transform (NTT) provides efficient algorithm for multiplying large degree polynomials. It is commonly used in cryptographic schemes that are based on the hardness of the Ring Learning With Errors problem (RLWE), which is a popular basis for post-quantum key exchange, encryption and digital signature.To apply NTT, modulus q should satisfy that , RLWE-based schemes have to choose an oversized modulus, which leads to excessive bandwidth. In this work, we present “Preprocess-then-NTT (PtNTT)” technique which weakens the limitation of modulus q, i.e., we only require or . Based on this technique, we provide new parameter settings for KYBER …

Understanding And Constructing Ake Via Double-Key Key Encapsulation Mechanism, Haiyang Xue, Xianhui Lu, Bao Li, Bei Liang, Jingnan He

Research Collection School Of Computing and Information Systems

Motivated by abstracting the common idea behind several implicitly authenticated key exchange (AKE) protocols, we introduce a primitive that we call double-key key encapsulation mechanism (2-key KEM). It is a special type of KEM involving two pairs of secret-public keys and satisfying some function and security property. Such 2-key KEM serves as the core building block and provides alternative approaches to simplify the constructions of AKE. To see the usefulness of 2-key KEM, we show how several existing constructions of AKE can be captured as 2-key KEM and understood in a unified framework, including widely used HMQV, NAXOS, Okamoto-AKE, and …

Investigating The Electrodeposition Of Plutonium And Curium For Safeguarding The Electrorefiner, Chantell L. Murphy

Nuclear Engineering ETDs

This research investigated the electrochemical deposition behavior of plutonium (Pu) and curium (Cm) for safeguarding the electrorefiner (ER) in a pyroprocessing facility. The main goal of this investigation was to evaluate the feasibility of using a safeguards concept called the neutron balance method to account for Pu in the ER. The neutron balance method relies on a known Pu/Cm ratio and measures neutrons from Cm-244 coming into and leaving a unit operation to track Pu. The application of the neutron balance approach for pyroprocessing facilities requires that Pu and Cm remain together in all extraction, product recovery, and waste streams. …

Triggers, Protectors, And Predictors In Episodic Migraine., Michael J. Marmura

Department of Neurology Faculty Papers

PURPOSE OF REVIEW: A wide variety of triggers prompt attacks in episodic migraine. Although experimental triggers such as glyceryl trinitrate reliably produce migraine, natural triggers are much less predictable and vary in importance between individuals. This review describes the most common triggers in episodic migraine and provides strategies for managing them in clinical practice.

RECENT FINDINGS: Multiple migraine attack triggers have been established based on patient surveys, diary studies, and clinical trials. Stress, menstrual cycle changes, weather changes, sleep disturbances, alcohol, and other foods are among the most common factors mentioned. Clinical studies have verified that fasting, premenstrual periods in …

Use Of Pv/T Panels To Meet The Building Loads Of Light Commercialized Buildings, Sadhvi Arora

Masters Theses and Doctoral Dissertations

This thesis deals with the analysis of a Photo Voltaic Thermal (PV/T) panel that is capable of producing simultaneously electric power and low-grade heat energy by absorbing the solar energy striking on its surface. A simple mathematical model is developed to estimate the electric power and heat energy gained by the PV/T panel. A water-to-water heat pump is employed that operates by absorbing the low-grade heat energy obtained from PV/T panel, in its evaporator, in order to produce high temperature hot water in its condenser. The high temperature hot water thus produced can be employed to meet the winter heating …

Accounting For Intraspecific Variation Transforms Our Understanding Of Artiodactyl Social Evolution, Monica Miles

Masters Theses and Doctoral Dissertations

A major goal in the study of mammalian social systems has been to explain evolutionary transitions in social traits. Recent comparative analyses have used phylogenetic reconstructions to determine the evolution of social traits but have omitted intraspecific variation in social organization (IVSO) and mating systems (IVMS). My objectives were to (i) summarize the extent of IVSO and IVMS in Artiodactyla and Perissodactyla and (ii) determine the ancestral social organization and mating system for Artiodactyla. Eighty-two percent of artiodactyls showed IVSO, whereas 31% exhibited IVMS. Eighty percent of perissodactyls had variable social organization and only one species showed IVMS. The ancestral …

A Change Plan For District Professional Learning And Teacher Collaboration In The Area Of Elementary English Language Arts Instruction, Scott Carlson

Dissertations

This change plan used Wagner et al.’s (2006) framework to assess the arenas of culture, context, conditions, and competencies of a small suburban school district to create a plan for professional learning and teacher collaboration in the area of English Language Arts instruction. However, a backmapping approach could be used to plan professional learning in any subject area. Building on the judgments and recommendations from my program evaluation, I hope to move the school district toward a more comprehensive model of transformational learning. A secondary goal of this change plan is to build the capacity of the district’s staff development …

Creating Conditions For A Collaborative Relationship Between Principals And Their Supervisors: A Change Initiative, Noah Riley

Dissertations

ABSTRACT

Studies by Kelley and Peterson (2002), Drago-Severson, Blum-DeStefano & Asghar (2013) and other researchers, have shown that in order for principals and other building leaders to be able to demonstrate the required expectations of “new” principal standards, they must engage in ongoing supervision, evaluation, coaching, and continuous career-long professional development. These studies also suggest that school districts, in their support and development of principals’ growth in competency capacity building, are more effective when the principal supervisor works in collaboration with principals they supervise/evaluate in a trusting, mutually respectful relationship of shared accountability for improving instruction and learning. This change …

The Role Of Human Capital And Innovative Entrepreneurship In Developing Countries, José Rolando Torrech Jr.

Theses and Dissertations

Human capital, innovation and entrepreneurship have long been associated with economic development in different contexts. However, in the recent past, several research studies carried out show that the complexity and technical nature of the everchanging business environment necessitated by technology have superseded the current human capital required to address innovative strategies in developing countries. Several scholars assert that although inadequate skills are a great challenge for entrepreneurs, more research needs to be done to break down the varying units affecting the impact of human capital on entrepreneurial development and economic growth. The purpose of the study was to investigate the …

Are We Safe Yet? Re-Evaluation Of The Performance Diagnostic Checklist-Safety (Pdc-Safety), Nelmar Jacinto Cruz

Theses and Dissertations

This study evaluated the utility of the Performance Diagnostic Checklist- Safety (PDC-Safety) (Martinez-Onstott, Wilder, & Sigurdsson, 2016) by comparing the effectiveness of a PDC-Safety indicated intervention with a PDC-Safety nonindicated intervention. The interventions targeted participants’ hand washing behavior at a clinic serving children with intellectual disabilities. Failure to wash hands at appropriate times could pose health risks to both behavior technicians and clients, so efforts should be made to increase the likelihood of hand washing. The results of the PDC-Safety suggested that the antecedents and information domain was most problematic. First, a non-indicated intervention, which included access to additional materials …

Initial screening performed at the Naval Research Laboratory indicated an IC50 of 84 nM for inhibition of a bacterial cholinesterase. It was also found to be 50% as effective as the control antiobiotic …

On Affect: Function And Phenomenology, Andreas Elpidorou

Faculty and Staff Scholarship

This paper explores the nature of emotions by considering what appear to be two differing, perhaps even conflicting, approaches to affectivity—an evolutionary functional account, on the one hand, and a phenomenological view, on the other. The paper argues for the centrality of the notion of function in both approaches, articulates key differences between them, and attempts to understand how such differences can be overcome.

Husein Djozo And His Fatwa On Collection And Distribution Of Zakat Funds, Hazim Fazlić

Occasional Papers on Religion in Eastern Europe

With the end of the Second World War, Yugoslavia became a de facto communist country. One of the policies of the new communist regime was to relegate religion entirely to the private sphere and to reduce the influence of religious communities in the public sphere. As a number of its legacies were expropriated, the Islamic Community of Yugoslavia was in need of new sources of funding. In order to reform a centuries-long practice of collection and distribution of religious contributions, zakat, and sadaqat al-fitr, a theoretical framework was needed to allow for that reform. This paper examines the …

Estudio Contrastivo Intercultural De Las Funciones Retóricas De Las Citas: La Producción De Textos Académicos En El Nivel De Posgrado Escritos En Español E Inglés, David Sánchez-Jiménez

Publications and Research

The main objective of this research is to discover which rhetorical functions were used in the Master´s thesis writing written by eight (8) American and eight (8) Spanish postgraduates in their na-tive language. A computerized tex-tual analysis of the rhetorical func-tion of citation was used to study this phenomenon (Petrić, 2007). The results obtained from the re-search showed that the different cultural conventions in the thesis writing indicate that when com-pared with native Spanish writers, the American writers of English use the highest number of cita-tions, and write a relatively longer Introduction and Conclusion parts. On the other hand, the …

A Data Synthesis Of Melodic Intonation Therapy, Jacqueline Ulfers

Undergraduate Honors Theses

The Baby Boomers, one of the largest (modern) generations, made of 76 million people, is entering the prime age to suffer a stroke, which often leads to aphasia. Melodic Intonation Therapy (MIT)is a current rehabilitation strategy for aphasia. Determining whether MIT is an effective and efficient treatment is vital because millions are at risk to suffer a stroke and effective rehabilitation strategies must be established. This honors thesis was a systematic review of previous studies written on melodic intonation therapy. The articles reviewed were chosen based on criteria including age of the patient, type of stroke, and immediacy of therapy. …

A Systematic Review Comparison Of Ketogenic Dietary Treatment Efficacy For Alzheimer’S Disease, Joshua Chavez

Undergraduate Honors Theses

There is evidence suggesting that Alzheimer’s disease (AD) pathology can be improved through the use of mechanistic/mammalian target of rapamycin (mTOR) inhibition therapy. Regulation of mTOR is responsible for mediating cell growth by regulating cell processes such as autophagy, transcription, and translation. Evidence suggests that a ketogenic dietary (KD) treatment may result in decreased mTOR signaling, thus making KD a potential treatment for AD. The objective of this systematic review was to explore the efficacy of current AD medications and compare the results to preliminary KD treatment for AD. The biochemical relevance of mTOR inhibition for AD and the relevance …

Implementating A Transitional Care Program To Reduce Hospital Readmissions In Medicare Recipients: A Research Translation Pilot Project, Gail Rattigan

Doctoral Scholarly Projects & Capstones

Patients discharged from hospital to home, especially the chronically ill and older adults, are too frequently readmitted within 30 days. The Centers for Medicare and Medicaid Services (n.d.; 2017) along with other interdisciplinary researchers have proposed, studied, and implemented strategies to decrease this excessive and expensive phenomenon. After the implementation of the Hospital Readmission Reduction Program in 2009, preventable readmissions have decreased but remain at unacceptable levels. Care transitions from hospital to home have been implicated as perilous and fraught with communication breakdown and lack of patient support and follow up. Strategies aimed at both the hospitalization phase and the …

Morality In An Apocalypse: A Character Analysis Using Kant And Maslow, Madison Smith

Perpetua: The Journal of Undergraduate Research at UAH

This article addresses how the relationship between morality and humanity evolves upon the disintegration of societal constraints due to the apocalypse in Station Eleven and The Road through the critical analysis of both novels. It examines the characters’ different behaviors spanning their normal personality to their threatened survival state. These mannerisms are scrutinized in respect to Immanuel Kant’s Categorical Imperative, specifically the universal and humanity formulations, as criterion to judge the characters’ moral boundaries in comparison to pre-collapse values. Furthermore, Abraham Maslow’s theory of self-actualization is employed as an additional means to evaluate the ethical principles of the characters under …
