A Hypothesis Testing Approach For Topology Error Detection In Power Grids, Wei Biao Wu, Maggie X. Cheng, Bei Gou

Computer Science Faculty Research & Creative Works

When the grid topology is changed due to incidents and the state estimator is not updated with the topological change, it is considered a topology error. In this paper, we develop a new method for detecting topology errors in power grids. The proposed method considers the measurement data as a nonstationary Gaussian process, explores the dependence structure of the underlying process. It detects errors by testing the hypothesis of whether the mean vector of a nonstationary Gaussian process is zero and does not rely on the convergence of the standard weighted least-squares (WLS) state estimation algorithm. It is very effective …

Cast2face: Assigning Character Names Onto Faces In Movie With Actor-Character Correspondence, Guangyu Gao, Mengdi Xu, Jialie Shen, Huangdong Ma, Shuicheng Yan

Research Collection School Of Computing and Information Systems

Automatically identifying characters in movies has attracted researchers' interest and led to several significant and interesting applications. However, due to the vast variation in character appearance as well as the weakness and ambiguity of available annotation, it is still a challenging problem. In this paper, we investigate this problem with the supervision of actor-character name correspondence provided by the movie cast. Our proposed framework, namely, Cast2Face, is featured by: 1) we restrict the assigned names within the set of character names in the cast; 2) for each character, by using the corresponding actor and movie name as keywords, we retrieve …

Managing Egress Of Crowd During Infrastructure Disruption, Teck Hou Teng, Shih-Fen Cheng, Trong-Nghia Truong, Hoong Chuin Lau

Research Collection School Of Computing and Information Systems

In a large indoor environment such as a sports arena or convention center, smooth egress of crowd after an event can be seriously affected if infrastructure such as elevators and escalators break down. In this paper, we propose a novel crowd simulator known as SIM-DISRUPT for simulating egress scenarios in non-emergency situations. To surface the impact of disrupted infrastructure on the egress of crowd, SIM-DISRUPT includes features that allow users to specify selective disruptions as well as strategies for controlling the distribution and egress choices of crowd. Using SIM-DISRUPT, we investigate effects of crowd distribution, egress choices and infrastructure disruptions …

A Privacy-Preserving Outsourced Functional Computation Framework Across Large-Scale Multiple Encrypted Domains, Ximeng Liu, Baodong Qin, Robert H. Deng, Rongxing Lu, Jianfeng Ma

Research Collection School Of Computing and Information Systems

In this paper, we propose a framework for privacy-preserving outsourced functional computation across large-scale multiple encrypted domains, which we refer to as POFD. With POFD, a user can obtain the output of a function computed over encrypted data from multiple domains while protecting the privacy of the function itself, its input and its output. Specifically, we introduce two notions of POFD, the basic POFD and its enhanced version, in order to tradeoff the levels of privacy protection and performance. We present three protocols, named Multi-domain Secure Multiplication protocol (MSM), Secure Exponent Calculation protocol with private Base (SECB), and Secure Exponent …

Hashtag Recommendation With Topical Attention-Based Lstm, Yang Li, Ting Liu, Jing Jiang, Liang Zhang

Research Collection School Of Computing and Information Systems

Microblogging services allow users to create hashtags to categorize their posts. In recent years,the task of recommending hashtags for microblogs has been given increasing attention. However,most of existing methods depend on hand-crafted features. Motivated by the successful use oflong short-term memory (LSTM) for many natural language processing tasks, in this paper, weadopt LSTM to learn the representation of a microblog post. Observing that hashtags indicatethe primary topics of microblog posts, we propose a novel attention-based LSTM model whichincorporates topic modeling into the LSTM architecture through an attention mechanism. Weevaluate our model using a large real-world dataset. Experimental results show that …

Semi-Automated Tool For Providing Effective Feedback On Programming Assignments, Min Yan Beh, Swapna Gottipati, David Lo, Venky Shankararaman

Research Collection School Of Computing and Information Systems

Human grading of introductory programming assignments is tedious and error-prone, hence researchers have attempted to develop tools that support automatic assessment of programming code. However, most such efforts often focus only on scoring solutions, rather than assessing whether students correctly understand the problems. To aid the students improve programming skills, effective feedback on programming assignments plays an important role. Individual feedback generation is tedious and painstaking process. We present a tool that not only automatically generates the static and dynamic program analysis outcomes, but also clusters similar code submissions to provide scalable and effective feedback to the students. We studied …

On The Vulnerabilities Of Voronoi-Based Approaches To Mobile Sensor Deployment, Novella Bartolini, Stefano Ciavarella, Simone Silvestri, Thomas La Porta

Computer Science Faculty Research & Creative Works

Mobile sensor networks are the most promising solution to cover an Area of Interest (AoI) in safety critical scenarios. Mobile devices can coordinate with each other according to a distributed deployment algorithm, without resorting to human supervision for device positioning and network configuration. In this paper, we focus on the vulnerabilities of the deployment algorithms based on Voronoi diagrams to coordinate mobile sensors and guide their movements. We give a geometric characterization of possible attack configurations, proving that a simple attack consisting of a barrier of few compromised sensors can severely reduce network coverage. On the basis of the above …

An integrated literature review approach was chosen due to the varying methodologies and multiple variables that have been used in the study of SBAR. The combined search terms of “SBAR”, “Communication”, and “Patient Safety” were entered into PubMed, …

Super Pac Funding And Its Impact On Voting Behavior In The U.S. House Of Representatives, Michael J. Scariano

Honors Theses

In light of the increasing levels of polarization in terms of voting behavior among members of the U.S. House of Representatives over the 112th, 113th, and 114th Congresses, coupled with the recent Supreme Court decision in Citizens United v. Federal Election Commision 558 U.S. 310 (2010), which authorized the use of unlimited fundraising and expenditure by outside groups in elections, the question was raised whether or not there was a correlation between these two occurrences. Specifically, this paper asks “what role does Super PAC funding play in the roll call vote choices of House Members of the 114th Congress?” To …

Secure Page, Jeffrey A. Schmidt

Masters Theses & Doctoral Dissertations

Secure Page allows IBM customer problem management applications to send mobile push notifications to technical support members for new work items. The current method of using simple SMS text to provide paging capabilities is limited in usage and is not a secure method for transmitting confidential information to the recipient.

An American Reset – Safe Water & A Workable Model Of Federalism, Cara Cunningham Warren

Duke Environmental Law & Policy Forum

In 2015, at least 3.9 million Americans were exposed to lead in their drinking water at legally unacceptable levels. An additional 18 million Americans were at risk because their water systems were not in compliance with federal rules designed to detect the presence of lead contamination and to ameliorate its impact. What’s more, in 82 percent of the cases where the violation related to a health standard, no formal state or federal enforcement action was taken.

These startling statistics indicate that the Flint Water Crisis (“Flint Water”) is not an isolated event. In fact, it is a case study that …

The Neglected History Behind Preble V. Maine Central Railroad Company: Lessons From The "Maine Rule" For Adverse Possession, Luke Meier

Hofstra Law Review

Under the “Maine Rule” for adverse possession, only possessors who have the requisite intent can perfect an adverse possession claim. The Maine Rule has been consistently criticized. The history behind the adoption of the Maine Rule, however, and the purpose it was to serve, have been ignored. This Article fills that void. This inquiry leads to some surprising revelations about the Maine Rule. The Maine Rule was originally adopted so as to distinguish prior Maine cases rejecting adverse possession in mistaken boundary situations. The purpose behind the Maine Rule, then, was to enable—rather than prohibit— adverse possession. The history surrounding …

Relocation Redux: Labrador Inuit Population Movements And Inequalities In The Land Claims Era, Kirk Dombrowski, Patrick Habecker, G. Robin Gauthier, Bilal Khan, Joshua Moses

Department of Sociology: Faculty Publications

The importance of community relocation experiences for aboriginal land claims movements is well documented; the role played by successful land claims in prompting ongoing out-migration is not. Data collected in 2011 on the lives of migrants are used to test three hypotheses: H1, Inuit leaving the land claims area for a nearby nonaboriginal city show markedly different social outcomes based on the length of time since migration; H2, these social outcomes map onto patterns of intergroup boundaries in their new communities; and H3, both of these outcomes are better explained by migration patterns after the land claims than by the …

Carbon And Nitrogen Dynamics Of Anthropogenically Disturbed Seagrass Ecosystems, Alison Shepherd

Theses and Dissertations

As atmospheric CO2 concentrations continue to rise, understanding factors that influence size and longevity of carbon (C) pools within coastal and marine ecosystems (i.e., “blue carbon”) is critical. In 2013, the global average atmospheric CO2 concentration reached 396 ppm, which was the highest recorded level in the last 800,000 years. Recent research acknowledges the importance of “blue carbon” in the global C cycle, finding that these ecosystems capture up to 70% of organic C in the marine realm, rendering them one of the most efficient C sinks on the planet. Specifically, seagrass ecosystems are critically important to the global C …

Developing A Multimetric Index To Assess Resaca Ecosystem Health, Buford J. Lessley

Theses and Dissertations

As the only freshwater ecosystem in the lower Rio Grande Valley aside from the Rio itself, resacas are critical habitat for many species of flora and fauna. Old distributaries of the Rio Grande, resacas provided conveyance routes moving floodwater to the Laguna Madre. Today these wetlands are novel ecosystems and are artificially maintained. Urbanization and agriculture have lead to sedimentation, habitat loss, contaminants, poor water quality, and invasive species. The objective of this study was to assess and monitor resaca pools and to compose the Resaca Health Index (RHI) from selected indicators of ecosystem structure and function including leaf litter …

Fluorine Atom Influence On Intramolecular Hydrogen Bonding, Isomerization And Methyl Group Rotation In Fluorinated Acetylacetones, Brett De Vries, Mark Muyskens

University Faculty Publications and Creative Works

1-Fluoro-pentane-2,4-dione (monofluoroacetylacetone, MFAA) is an asymmetric β-diketone with a strong intramolecular hydrogen bond similar to acetylacetone (AA) and its fluorinated analogs 1,1,1-trifluoro-(TFAA), and 1,1,1,5,5,5-hexafluoroacetylacetone (HFAA). The presence of a fluorine atom in MFAA has the potential to open an HF elimination channel in its gas-phase photochemistry motivating this study of MFAA hydrogen bonding by computer modeling using Density Functional Theory (DFT). As a context, we also report DFT modeling of AA and selected fluorinated acetylacetones: 1,1-difluoro-pentane-2,4-dione (difluoroacetylacetone, DFAA), TFAA, and HFAA. The most stable molecular structure for all three asymmetric β-diketones (MFAA, DFAA and TFAA) is the isomer with the …

The Nature Of God: Perceptions Of God With Exposure To Nature And Natural Events, Holly Ann Kolberg

All-Inclusive List of Electronic Theses and Dissertations

Research studies have shown that the sense of awe evoked by natural settings may be associated with transcendental thinking about God. Similarly, other researchers have suggested that people attribute events to God when they cannot develop a sufficient naturalistic explanation for a phenomenon. People appear to prefer attributing events to a benevolent God but will modify their beliefs to assume that God is punitive if event outcomes do not appear to favor their well-being or religious attributions do not accommodate a situation. In the current study, the goal was to evaluate how exposure to photographs of different environments influenced beliefs …

Development Of A Measure Of Model Fidelity For Mental Health Crisis Resolution Teams, Brynmor Lloyd-Evans, Gary R. Bond, Torleif Ruud, Ada Ivanecka

Dartmouth Scholarship

Crisis Resolution Teams (CRTs) provide short-term intensive home treatment to people experiencing mental health crisis. Trial evidence suggests CRTs can be effective at reducing hospital admissions and increasing satisfaction with acute care. When scaled up to national level however, CRT implementation and outcomes have been variable. We aimed to develop and test a fidelity scale to assess adherence to a model of best practice for CRTs, based on best available evidence.
