Semi-Automatic Identification Of Synonyms In Structured Knowledge Representations, Thomas C. Taylor

Theses

Synonym support is an important aspect of querying knowledge bases, but current approaches to generating such support is difficult and error-prone. Automating the process of identifying synonyms in structured knowledge representations is therefore an important pursuit. This thesis presents an ensemble approach that incorporates several methods and knowledge sources heretofore used individually. A case study shows that the approach performs better than individual methods, and that it may be used to reduce efforts to identify synonyms.

The Study Of Cybersecurity Algorithms From Traditional Computing To The Internet Of Things, Daniel Davis

Theses

A progressive approach to teach students how to develop and deploy cybersecurity algorithms across a wide range of heterogeneous computing devices is proposed. Data confidentiality and data integrity can be ensured when sensitive information is transferred between various types of devices over insecure communication channels by using cybersecurity algorithms. A step-by-step procedure to teach students cybersecurity algorithms on devices ranging from personal computers to devices deployed in the Internet of Things ecosystem is needed. We develop four learning modules that offer students the opportunity to explore commonly utilized cybersecurity algorithms across several heterogeneous devices. Students are able to utilize our …

Second Order Sliding Mode Control Using Nonlinear Dynamic Sliding Manifold : A Lyapunov Approach, Bhargav Chava

Theses

Second order Sliding Mode Control (2-SMC) algorithms require knowledge of derivative of sliding variable, which is to be implemented using 2-SM differentiators. The use of 2-Sliding Mode differentiators causes loss of accuracy. Hence, the approach known as nonlinear dynamic sliding manifold (NDSM) approach is used to design a 2-SM control algorithm without the knowledge of derivative of sliding variable. The main contribution of the thesis is proof of finite time convergence of 2-SMC using NDSM approach by Lyapunov function technique. Also an adaptive 2-SM control law is proposed for perturbed systems with unknown boundaries using NDSM approach to avoid overestimation …

Philosophizing About God And Nature : Connections And Divisions In The Writings Of Isaac Newton, Joshua Riddle

Theses

For several decades, scholars have argued about the relationship between Isaac Newton’s works in science (or natural philosophy), “chymistry,” religion, and theology. Of particular interest has been how his natural philosophy and religion/theology related to each other. Some scholars claim a significant connection between them, even claiming they are part of a “seamless unity” in Newton’s thinking. Other, more skeptical, scholars call for a localized approach to his writings. By entering into this debate and analyzing many of Newton’s manuscripts, I argue that Newton held onto significant disciplinary distinctions in his writings, but also was willing to make small connections …

The Study Of Nf-Κb Peptide Mimics And How Proteins Bind Dna, Allee M. Murray

Honors College Theses

The protein complex nuclear factor kappa B (NF-κB) is widely considered to be one of the most influential transcription factors when studying cellular functions. Peptide mimics of NF-κB aim to inhibit DNA binding in order to displace the natural transcription factor, therefore inhibiting transcription and translation. In theory, NF-κB is not the problem; the real problem lies in directing the synthesis and expression of harmful proteins. In conjunction with this, the project aims to study NF-κB and its structure and function to determine what criteria are important for the binding of DNA in order to design a peptide that comes …

Towards A Science Of Security Games, Thanh Hong Nguyen, Debarun Kar, Matthew Brown, Arunesh Sinha, Albert Xin Jiang, Milind Tambe

Research Collection School Of Computing and Information Systems

Security is a critical concern around the world. In many domains from counter-terrorism to sustainability, limited security resources prevent full security coverage at all times; instead, these limited resources must be scheduled, while simultaneously taking into account different target priorities, the responses of the adversaries to the security posture and potential uncertainty over adversary types.Computational game theory can help design such security schedules. Indeed, casting the problem as a Bayesian Stackelberg game, we have developed new algorithms that are now deployed over multiple years in multiple applications for security scheduling. These applications are leading to real-world use-inspired research in the …

Demo: Profiling Power Utilization Behaviours Of Smartwatch Applications, Joseph Joo Keng Chan, Lingxiao Jiang, Rajesh Krishna Balan, Youngki Lee, Archan Misra

Research Collection School Of Computing and Information Systems

Smartwatches complement the main mobile phone and are able to profile user-activity as well as provide links, updates and notifications with work or personal utilities (e.g. Email, Social Media, Messaging etc.). Although very promising, smartwatches are still limited by low battery life. This is due to the small size of the battery as well as the need to continuously perform sensing. Battery drain issues by apps as well as the system are a common complaint by users. Improved tools for power analysis and profiling of smartwatch apps can help both developers (by providing a platform for pre-release analysis) and users …

Demo: Sensing Gamers' Emotions Using Physiological Sensors, Sinh Huynh, Rajesh Krishna Balan, Youngki Lee

Research Collection School Of Computing and Information Systems

Understanding emotions of gamers can benefit game designers in various ways. How gamers feel while they playing a game can be treated as valuable user feedback to improve the development process of that game. Sensing player emotions also enables game designers to create adaptive game that can adjust itself to provide best gaming experience based on player emotions. However, how to effectively evaluate emotions of gamers is still an open research challenge. Two common techniques to evaluate emotional state are using self-assessments such as questionnaires or interviews, and to recognize expressed emotions by analyzing videos or images of facial expression, …

Powerforecaster: Predicting Power Impact Of Mobile Sensing Applications At Pre-Installation Time, Chulhong Min, Youngki Lee, Chungkuk Yoo, Seungwoo Kang, Inseok Hwang, Junehwa Song

Research Collection School Of Computing and Information Systems

Today's smartphone application (hereinafter 'app') markets miss a key piece of information, power consumption of apps. This causes a severe problem for continuous sensing apps as they consume significant power without users' awareness. Users have no choice but to repeatedly install one app after another and experience their power use. To break such an exhaustive cycle, we propose PowerForecaster, a system that provides users with power use of sensing apps at pre-installation time. Such advanced power estimation is extremely challenging since the power cost of a sensing app largely varies with users' physical activities and phone use patterns. We observe …

A Tool-Free Calibration Method For Turntable-Based 3d Scanning Systems, Xufang Pang, Rynson W.H. Lau, Zhan Song, Shengfeng He, Shengfeng He

Research Collection School Of Computing and Information Systems

Turntable-based 3D scanners are popular but require calibration of the turntable axis. Existing methods for turntable calibration typically make use of specially designed tools, such as a chessboard or criterion sphere, which users must manually install and dismount. In this article, the authors propose an automatic method to calibrate the turntable axis without any calibration tools. Given a scan sequence of the input object, they first recover the initial rotation axis from an automatic registration step. Then they apply an iterative procedure to obtain the optimized turntable axis. This iterative procedure alternates between two steps: refining the initial pose of …

Current Challenges In Atrial Fibrillation Ablation, Edward John Davies

Peninsula Medical School Theses

The ablative management of atrial fibrillation, despite a number of landmark discoveries, remains one of the most challenging fields in interventional electrophysiology. It is generally accepted that successful isolation of the pulmonary veins is a highly effective way of managing paroxysmal forms of AF. However, despite almost a decade of research into alternative lesion patterns, the solution to persistent AF remains beyond our grasp. A variety of strategies have been proposed to target key areas in the atria; these use various complex mapping systems, usually based on tailored lesion sets to try and improve outcomes. None have proven to be …

Social Justice And Human Rights In Education Policy Discourse: Assessing Nelson Mandela's Legacy, Abrehet Gebremedhin, Devin Joshi

Research Collection School of Social Sciences

Twenty years after South Africa's democratisation, Nelson Mandela's passing has prompted scholars to examine his legacy in various domains. Here we take a look at his legacy in education discourse. Tracing Mandela's thoughts and pronouncements on education we find two major emphases: a view of education as a practical means to economic development, and education as a means to social justice, human rights, and democracy. Assessing the legacy of these twin emphases, we conducted qualitative and quantitative content analysis of turning point documents in education policy and annual reports from the respective South African ministries of education over the last …

Assessment Of Measured And Perceived Microclimates Within A Tropical Urban Forest, Winston T. L. Chow, Siti Nur ‘Assyakirin Binte Ali Akbar, Su Li Heng, Matthias Roth

Research Collection School of Social Sciences

Urban greenery is a favoured approach applied towards reducing urban warmth and climate discomfort, but ascertaining its measured and perceived effectiveness in tropical climates is relatively understudied. To this end, we investigated microclimate differences within an urban park (the Singapore Botanic Gardens) to assess if variations in plot-scale land cover affect both objective (measured) and subjective (surveyed) microclimate data. Over two monsoonal seasons, we obtained data from four distinct sites—a tropical rainforest stand, a palm tree valley, a water-body feature, and the park visitors’ centre. Measured climate data (e.g. air temperature, vapour pressure, wind velocity and globe temperatures) were used …

One Swallow Does Not Make Spring: A Critical Juncture Perspective On The Eu Sanctions In Response To The Arab Spring, Andreas Boogaerts, Clara Portela, Edith Drieskens

Research Collection School of Social Sciences

This article examines to what extent the Arab Spring constitutes a critical juncture – a major turning point – for the EU’s sanctions policy towards Egypt, Libya, Syria and Tunisia. Based on a multidimensional critical juncture operationalization, we find that the Arab Spring only constitutes such a turning point for the EU’s sanctions policy towards Syria. Both the level and nature of measures differ substantially from previous years. By contrast, the EU’s sanctions practice towards Libya, Egypt and Tunisia shows more resilience. More generally, changes in the nature of the measures are prominent, whereas changes in the level of the …
