Characterization And Visualization Of Sophisticated Scanning Attacks, Maggie Xiaoyan Cheng, Quanmin Ye, Robert F. Erbacher

Computer Science Faculty Research & Creative Works

Detection of sophisticated stealthy network scans requires analyzing large amounts of network data collected over long periods of time. The sheer volume of the data prohibits efficient detection from a pure algorithmic approach. However timely detection of such sophisticated scanning attacks is critical since the attacker employing these approaches is usually well-resourced and potentially can bring high impact to the network than a naive attacker can. To detect such sophisticated scans, we propose the integration of algorithmic detection and visualization for human detection to simultaneously optimize computational complexity and human analyst time. The proposed approach provides real world detection capabilities …

Luminescent Laf₃:Ce-Doped Organically Modified Nanoporous Silica Xerogels, Mingzhen Yao, Ryan Hall, Wei Chen, Dhairyashil Mohite, Nicholas Leventis, N. Lu, J. Wang, M. J. Kim, H. Luo, Hongbing Lu

Chemistry Faculty Research & Creative Works

Organically modified silica compounds (ORMOSILs) were synthesized by a sol-gel method from amine-functionalized 3-aminopropyl triethoxylsilane and tetramethylorthosilicate and were doped in situ with LaF₃:Ce nanoparticles, which in turn were prepared either in water or in ethanol. Doped ORMOSILs display strong photoluminescence either by UV or X-ray excitation and maintain good transparency up to a loading level of 15.66% w/w. The TEM observations demonstrate that ORMOSILs remain nanoporous with pore diameters in the 5-10 nm range. LaF₃:Ce nanoparticles doped into the ORMOSILs are rod-like, 5 nm in diameter and 10-15 nm in length. Compression testing indicates that …

Probability Of Failure For Slopes With Sensitivity Analysis, Michelle Deng, Ronaldo Luna

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The significance of random variables on the probability of failure of slopes is generally evaluated by changing a different set of values for each variable and repeating the approach several times to conclude a trend. This method is very straightforward but requires time and computational resources; and it is inefficient especially when the number of random variables is large. This paper presents an analysis approach in which the sensitivity analysis is introduced to quantify the influence of the random variables on the probability of failure for slopes. In this study, the factor of safety of the slope was determined using …

Effect Of Moist Curing And Use Of Lightweight Sand On Characteristics Of High-Performance Concrete, Soo Duck Hwang, Kamal H. Khayat, Dalia Youssef

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Factorial design approach was undertaken to determine the effect of initial moist-curing duration (0 and 6 days) on properties of high-performance concrete (HPC) made with different water-to-cementitious materials ratios (w/cm) of 0.30 and 0.40 and sand substitution rates with lightweight sand (LWS) of 0 and 30 %, by volume. Mechanical properties of HPC are shown to be mainly affected by w/cm and total shrinkage of concrete by the LWS replacement rate and initial moist-curing period. It should be noted that concrete made with 30 % LWS replacement that did not receive any moist-curing exhibited lower shrinkage than moist-cured concrete prepared …

Intercalation And Delamination Of Layered Carbides And Carbonitrides, Olha Mashtalir, Michael Naguib, Vadym Mochalin, Yohan Dall'agnese, Min Heon, Michel W. Barsoum, Yury G. Gogotsi

Chemistry Faculty Research & Creative Works

Intercalation and delamination of two-dimensional solids in many cases is a requisite step for exploiting their unique properties. Herein we report on the intercalation of two-dimensional Ti₃C₂, Ti₃ CN and TiNbC - so called MXenes. Intercalation of hydrazine, and its co-intercalation with N,N-dimethylformamide, resulted in increases of the c-lattice parameters of surface functionalized f-Ti₃C₂, from 19.5 to 25.48 and 26.8 Å, respectively. Urea is also intercalated into f-Ti₃C₂. Molecular dynamics simulations suggest that a hydrazine monolayer intercalates between f-Ti₃C₂ layers. Hydrazine is also intercalated …

With the increasing pressures of achieving higher student scores in emphasized content areas, teachers' instruction in science, social studies, music and art has been reduced to provide additional time for teaching reading and mathematics.These lost instructional areas often allowed students to express themselves creatively. Therefore, educators need to find a way to incorporate creativity into content areas like reading and mathematics.

This 16 week repeated measures study examined second grade students' academic and creative performance on figural transformation drawings during an extended reading-science-creativity integrated unit. A …

Simultaneous Routing And Multiplexing In Ad Hoc Networks With Mimo Links, Maggie Cheng, Quanmin Ye, Xiaochun Cheng

Computer Science Faculty Research & Creative Works

This paper addresses how to leverage the spatial multiplexing function of MIMO links to improve wireless network throughput. Wireless interference modeling of a half-duplex MIMO node is presented, based on which, routing, spatial multiplexing and scheduling are jointly considered in one optimization model. A linear program-based algorithm is proposed for the joint optimization, and numerical simulation results show that the joint optimization of routing with spatial-temporal multiplexing is superior to the separate design approaches, including separating routing from the other two designs, and separating scheduling from the other two designs. © 2013 IEEE.

Optimization Of Object Queries On Collections Using Annotations For The String Valued Attributes, Venkata Krishna Suhas Nerella, Sanjay K. Madria, Thomas Weigert

Computer Science Faculty Research & Creative Works

Object oriented programming languages raised the level of abstraction by supporting the explicit first-class query constructs in the programming codes. The query constructs can be optimized by leveraging the techniques of query optimization from the domain of databases. The existing optimization approaches such as JQL, however, incur high run time overhead as optimizations are performed only at run time. Therefore, in this paper, we propose an approach that performs the query optimization at compile time utilizing the metadata annotations in the source code. The proposed approach first collects the data from the sample execution of the program and extracts the …

Pcv: Predicting Contact Volume For Reliable And Efficient Data Transfers In Opportunistic Networks, Shiraz Qayyum, Mehrab Shahriar, Mohan Kumar, Sajal K. Das

Computer Science Faculty Research & Creative Works

Exploiting opportunistic contacts between mobile devices to enable deployment of real applications through reliable and efficient data transfers poses a significant research challenge. Indeed, accurate prediction of contact volume, defined as the maximum amount of data transferable during a contact, can improve performance of deployments. However, existing schemes for estimating contact volume that make use of preconceived patterns or contact time distributions may not be applicable in uncertain environments. In this paper, we propose a novel scheme called PCV that predicts contact volume in soft real-time to enable efficient and reliable data transfers in opportunistic networks. An Android Application that …

Sleep Duration And Breast Cancer Phenotype, Ali Khawaja, Santosh Rao, Li Li, Cheryl L. Thompson

Medical College Documents

Emerging evidence suggests that short sleep is associated with an increased risk of cancer; however, little has been done to study the role of sleep on tumor characteristics. In this study, we evaluated the relationship between sleep duration and tumor phenotype in 972 breast cancer patients. Sleep duration was inversely associated with tumor grade (univariate P = 0.032), particularly in postmenopausal women (univariate P = 0.018). This association did not reach statistical significance after adjustments for age, race, body mass index, hormone replacement therapy use, alcohol consumption, smoking, and physical activity in the entire study sample (P = 0.052), but …

Cave Ventilation Is Influenced By Variations In The Co2-Dependent Virtual Temperature, Enrique P. Sánchez-Cañete, Penélope Serrano-Ortiz, Francisco Domingo, Andrew S. Kowalski

International Journal of Speleology

Dynamics and drivers of ventilation in caves are of growing interest for different fields of science. Accumulated CO₂ in caves can be exchanged with the atmosphere, modifying the internal CO₂ content, affecting stalagmite growth rates, deteriorating rupestrian paintings or creating new minerals. Current estimates of cave ventilation neglect the role of high CO₂ concentrations in determining air density – approximated via the virtual temperature (T_v) –, affecting buoyancy and therefore the release or storage of CO₂. Here we try to improve knowledge and understanding of cave ventilation through the use of T …

The Use Of Passive Seismological Imaging In Speleogenetic Studies; An Example From Kanaan Cave, Lebanon, Carole Nehme, Christophe Voisin, Armand Mariscal, Pierre-Charles Gérard, Cécile Cornou, Badr Jabbour-Gédéon, Samer Amhaz, Nancy Salloum, Nada Badaro-Saliba, Jocelyne Adjizian-Gérard, Jean-Jacques Delannoy

International Journal of Speleology

Among many parameters that control the evolution of caves stands the volume of unconsolidated clay sediments generally produced by the alteration of the calcareous rocks. Here we introduce the use of a passive seismological imaging technique to investigate the clay deposits and estimate its total volume in a cave. Applied for the first time for speleogenesis studies, the HVSR (Horizontal / Vertical Spectral Ration) is a geophysical technique that can help better interpret cave geomorphology. We apply seismological spectral techniques (H/V ratio) on ambient noise vibrations to derive the clay volume, as well as its shape. This technique applied on …

Screening Legal Claims Based On Third-Party Litigation Finance Agreements And Other Signals Of Quality, Michael B. Abramowicz, Omer Alper

GW Law Faculty Publications & Other Works

The advent of third-party litigation finance introduces a new gatekeeper to the legal process. Before deciding to lend money to a plaintiff, a litigation finance company will conduct at least some review and make an assessment of the quality of the case.

Since litigation finance loans are generally nonrecourse, a litigation finance company is likely to refuse to loan money to plaintiffs with the weakest cases. Such voluntary claim screening may improve social welfare by reducing the incidence of frivolous claims. But the volume of frivolous claims may still be higher than it would be in a world without third-party …

Effectiveness Of Teacher Professional Learning : Enhancing The Teaching Of Fractions In Primary Schools, Derek Hurrell

Theses: Doctorates and Masters

This study was motivated by the need to develop professional learning for primary school teachers that would support them to more effectively teach the mathematics topic of fractions. What seemed evident, was that previous professional learning attended by teachers had not adequately met their needs.

The aim of this study was to investigate whether professional learning, with a focus on subject content knowledge, pedagogical knowledge and reflective practice could enhance primary school teachers’ PCK for teaching fractions and make them more confident teachers of fractions. Demonstrating this to be the case would have wide implications for the development of professional …
