Usability And Security Support Offered Through Adsl Router User Manuals, Patryk Szewczyk

Australian Information Security Management Conference

ADSL routers are often used as either the target or the means for cyber crime. Many ADSL router threats could be mitigated through the effective use of inbuilt security controls and firmware updates available from vendors. Unfortunately, end‐users typically lack the technical expertise to correctly configure and secure the device. Subsequently, end‐users are reliant on well documented procedures provided by vendors in their user manuals and quick start guides. This study investigates the usability and security recommendations and encouragements put forth by vendors in their user manuals. The study demonstrates that user manual usability does not conform to ideal technical …

Complementary Feature Level Data Fusion For Biometric Authentication Using Neural Networks, Mark Abernethy, Shri Rai

Australian Information Warfare and Security Conference

Data fusion as a formal research area is referred to as multi‐sensor data fusion. The premise is that combined data from multiple sources can provide more meaningful, accurate and reliable information than that provided by data from a single source. There are many application areas in military and security as well as civilian domains. Multi‐sensor data fusion as applied to biometric authentication is termed multi‐modal biometrics. Though based on similar premises, and having many similarities to formal data fusion, multi‐modal biometrics has some differences in relation to data fusion levels. The objective of the current study was to apply feature …

The Influence And Deception Of Twitter: The Authenticity Of The Narrative And Slacktivism In The Australian Electoral Process, Benjamin Waugh, Maldini Abdipanah, Omid Hashemi, Shaquille A. Rahman, David M. Cook

Australian Information Warfare and Security Conference

It is uncertain how many discreet users occupy the social media community. Fake tweets, sock puppets, force‐multipliers and botnets have become embedded within the fabric of new media in sufficient numbers that social media support by means of quantity is no longer a reliable metric for determining authority and influence within openly expressed issues and causes. Election campaigns, and their associated political agendas, can now be influenced by non‐specific virtual presences that cajole and redirect opinions without declaring identity or allegiance. In the lead up to the 2013 Australian Federal Election, the open source Twitter activity for the two major …

Adjusted Tornado Probabilities, Holly M. Widen, James B. Elsner, Cameron Amrine, Rizalino B. Cruz, Erik Fraza, Laura Michaels, Loury Migliorelli, Brendan Mulholland, Michael Patterson, Sarah Strazzo, Guang Xing

Publications

Tornado occurrence rates computed from the available reports are biased low relative to the unknown true rates. To correct for this low bias, the authors demonstrate a method to estimate the annual probability of being struck by a tornado that uses the average report density estimated as a function of distance from nearest city/town center. The method is demonstrated on Kansas and then applied to 15 other tornado-prone states from Nebraska to Tennessee. States are ranked according to their adjusted tornado rate and comparisons are made with raw rates published elsewhere. The adjusted rates, expressed as return periods, arestates, including …

Magnetic Inhibition Of Convection And The Fundamental Properties Of Low-Mass Stars. I. Stars With A Radiative Core, Gregory A. Feiden, Brian Chaboyer

Dartmouth Scholarship

Magnetic fields are hypothesized to inflate the radii of low-mass stars—defined as less massive than 0.8 M _☉—in detached eclipsing binaries (DEBs). We investigate this hypothesis using the recently introduced magnetic Dartmouth stellar evolution code. In particular, we focus on stars thought to have a radiative core and convective outer envelope by studying in detail three individual DEBs: UV Psc, YY Gem, and CU Cnc. Our results suggest that the stabilization of thermal convection by a magnetic field is a plausible explanation for the observed model-radius discrepancies. However, surface magnetic field strengths required by the models are significantly stronger …

The Development And Gentrification Of Musical Commerce In Williamsburg, Virginia, 1716-1775, Joshua R. Lehuray

Theses and Dissertations

This thesis explores the burgeoning musical commerce industry in Williamsburg, Virginia between approximately 1716 to 1775. It especially focuses on the gentrification of this industry and the ways in which elite Virginians made use of music to establish themselves as inheritors of British culture and musical entertainment. A diversity of musical businesses appeared in Williamsburg during the eighteenth century, including instrument sellers, music and dancing teachers, and two theaters utilized by theatrical troupes, to name a few. Drawing on evidence from the Virginia Gazette, as well as journals, letters, playhouse reports, and account books, the thesis concludes that music provided …

Drainage Structure Datasets And Effects On Lidar-Derived Surface Flow Modeling, Ruopu Li, Zhenghong Tang, Xu Li, Jessie Winter

School of Natural Resources: Faculty Publications

With extraordinary resolution and accuracy, Light Detection and Ranging (LiDAR)-derived digital elevation models (DEMs) have been increasingly used for watershed analyses and modeling by hydrologists, planners and engineers. Such high-accuracy DEMs have demonstrated their effectiveness in delineating watershed and drainage patterns at fine scales in low-relief terrains. However, these high-resolution datasets are usually only available as topographic DEMs rather than hydrologic DEMs, presenting greater land roughness that can affect natural flow accumulation. Specifically, locations of drainage structures such as road culverts and bridges were simulated as barriers to the passage of drainage. This paper proposed a geospatial method for producing …

Mechanical Properties Of Hydrated Acoustically Sensitive Alginate-Based Microcapsules Confined In A Microfluidic Device As A Function Of Size And Composition, Maryam Mobed-Miremadi, Mallika Keralapura, Tiffany Fong, Rogel Camba

Bioengineering

Understanding the mechanical properties of alginate-based microcapsules according to size and chemical composition allows researchers to zero in on the treatment and methods required to engineer optimized implantable alginate-based artificial cells for chemotherapy. Cross-linked medium viscosity alginate capsules ranging from 1.1% (w/v)-1.8% (w/v) in composition and 200 μm-1200 μm in size, encapsulating ultrasound contrast agents and blue dextran were compressed within a 40 μm high polydimethylsiloxane microfluidic device and subsequently examined using 2D microscopy for strain deformation aimed at the calculation of poisson ratios and volume loss postcompression. Results indicate a decrease in Poisson ratio as a function of alginate …

Electron-Impact Vibrational Excitation Of Vibrationally Excited H2 Molecules Involving The Resonant 2(Sigma)G+ Rydberg-Excited Electronic State, R Celiberto, R. K. Janev, V Laporta, J Tennyson, J. M. Wadehra

Physics and Astronomy Faculty Research Publications

Electron-impact theoretical cross sections and rate coefficients for vibrational excitation of vibrationally excited H2 molecules, occurring through the H−2 resonant species in the 2Σ+g Rydberg-excited electronic state, are presented. The cross sections are calculated as functions of the incident electron energy by adopting the local-complex-potential model for resonant collisions and by using ab initio calculated molecular potentials and resonance widths. The calculations have been extended to all possible vibrational transitions linking all 15 vibrational levels of the electronic ground state of the H2 molecule. The corresponding rate coefficients are also obtained as a function of the electron temperature by assuming …

The Undergrad's Dilemma: N-Person Games And Information Asymmetry In Undergraduate Course Selection, Michael A. Verlezza

Honors Program Theses and Projects

In 2012, the White House released its College Scorecards for institutions of higher education. In their overview, the White House states that Bridgewater State University in Bridgewater, MA, has a six-year graduation rate of just 51.7 percent. By approaching the question of low graduation rates as a consequence of economic inefficiency, my research led me to treat undergraduate course selection as a Nash n-person game. From there, my investigation led to an analysis of information asymmetry as I attempted to identify the various internal and external information sources driving course selection. Specific attention was given to Bridgewater State’s internal system, …

Optimization And Spatial Queueing Models To Support Multi-Server Dispatching Policies With Multiple Servers Per Station, Sardar Ansari

Theses and Dissertations

In this thesis, we propose novel optimization and spatial queueing models that expand the currently existing methods by allowing multiple servers to be located at the same station and multiple servers to be dispatched to a single call. In particular, a mixed integer linear programming (MILP) model is introduced that determines how to locate and dispatch ambulances such that the coverage level is maximized. The model allows multiple servers to be located at the same station and balances the workload among them while maintaining contiguous first priority response districts. We also propose an extension to the approximate Hypercube queueing model …

A Comparison Of Evidence Fusion Rules For Situation Recognition In Sensor-Based Environments, Susan Mckeever, Juan Ye

Conference papers

Dempster-Shafer (DS) theory, and its associated Dempster rule of combination, has been widely used to determine belief based on uncertain evi-dence sources. Variations to the original Dempster rule of combination have appeared in the literature to support particular scenarios where unreliable results may result from the use of original DS theory. While theoretical explanations of the rule variations are explained, there is a lack of empirical comparisons of the DS theory and its variations against real data sets. In this work, we examine several variations to DS theory. Using two real-world sensor data sets, we com-pare the performance of DS …

Improvement Of Dynamic Performance Of The Grid Connected Photovoltaic (Pv) System By Series Compensating Devices, Md Kamal Hossain

Electronic Theses and Dissertations Archive

This study proposes the bridge type fault current limiter (BFCL) and series dynamic braking resistor (SDBR) methodologies to enhance the low voltage ride through (LVRT) capability of the PV plant during network faults. This work also focuses on smoothing out the PV power fluctuation due to variable irradiance. To achieve this, the output power of diversely located identical and small PV plants, instead of a big PV plant in a certain area, is integrated. Simulations performed through the Matlab/Simulink software shows that the terminal voltage obtained from the proposed protection schemes maintains the grid code, and hence the PV systems …

Propensity Score Methods In Estimating Conditional Hazard Ratio, Wen Feng

Electronic Theses and Dissertations Archive

Various simulations have been done to demonstrate how propensity score methods perform in estimating mean difference, proportion, odds ratio and marginal hazard ratio, however, few rigorous simulations have been done to evaluate the performance. We conduct an extensive series of simulations to demonstrate the performance of propensity score methods in estimating conditional hazard ratio. For each propensity method, we characterize the conditions to 7 propensity score scenarios, each contains a different set of variables. For each scenario, we apply four propensity methods to estimate conditional hazard ratio. Meanwhile, we also use multivariate Cox model (conventional Cox model) to estimate conditional …

Peakon, Pseudo-Peakon, And Cuspon Solutions For Two Generalized Camassa- Holm Equations, Jibin Li, Zhijun Qiao

School of Mathematical & Statistical Sciences Faculty Publications

In this paper, we study peakon, cuspon, and pseudo-peakon solutions for two generalized Camassa-Holm equations. Based on the method of dynamical systems, the two generalized Camassa-Holm equations are shown to have the parametric representations of the solitary wave solutions such as peakon, cuspon, pseudo-peakons, and periodic cusp solutions. In particular, the pseudo-peakon solution is for the first time proposed in our paper. Moreover, when a traveling system has a singular straight line and a heteroclinic loop, under some parameter conditions, there must be peaked solitary wave solutions appearing.
