Detecting Undetectable Computer Viruses, Sujandharan Venkatachalam

Master's Projects

Signature-based detection relies on patterns present in viruses and provides a relatively simple and efficient method for detecting known viruses. At present, most anti-virus systems rely primarily on signature detection. Metamorphic viruses are one of the most difficult types of viruses to detect. Such viruses change their internal structure, which provides an effective means of evading signature detection. Previous work has provided a rigorous proof that a fairly simple metamorphic engine can generate viruses that will evade any signature-based detection. In this project, we first implement a metamorphic engine that is provably undetectable—in the sense of signature-based detection. We then …

Geometrical Structure And Analysis Of Association Rule, Rajat Sar

Master's Projects

Association rule mining helps us to identify the association between items from a large transactional data set. It has always been a time consuming process because of repeatedly scanning of the data set. Apriori Algorithm [1] and FP-Tree Algorithm [2] are the two methods to find out the association of items in a large transactional item set. Both the above algorithm works differently (Apriori follows Bottom-Up Approach & FP-Tree follows Top-Down Approach) in order to get the association. Associations of items generated from the above two algorithms can be represented in geometry. The geometrical form of associations is called Simplical …

Security In Peer-To-Peer Sip Voip, Richa Marwaha

Master's Projects

VoIP (Voice over Internet Protocol) is one of the fastest growing technologies in the world. It is used by people all over the world for communication. But with the growing popularity of internet, security is one of the biggest concerns. It is important that the intruders are not able to sniff the packets that are transmitted over the internet through VoIP. Session Initiation Protocol (SIP) is the most popular and commonly used protocol of VoIP. Now days, companies like Skype are using Peer-to-Peer SIP VoIP for faster and better performance. Through this project I am improving an already existing Peer-to-Peer …

Spatial And Spatial-Temporal Analysis Of Grizzly Bear Movement Patterns As Related To Underlying Landscapes Across Multiple Scales, Barbara Lynn Carra

Theses and Dissertations (Comprehensive)

Studying the movements of grizzly bears (Ursus arctos) in Alberta is imperative for scientifically informed management practices. To properly balance industry requirements with conservation imperatives, it is necessary to understand the spatial and spatial-temporal movement patterns of grizzly bears as they relate to underlying landscape properties. As part of the Foothills Research Institute Grizzly Bear Research Program, this dissertation explored both fine and largescale movement patterns generated from global positioning system (GPS) radiotelemetry data.

Between 1999 and 2005, grizzly bears were captured and radio-collared across western Alberta. The temporal resolution of GPS data collection had a large impact …

Littoral Cells, Longshore Transport And Wave Climate: An Examination Of Littoral Transport Along The Western Shore Of Prince Edward County, Ontario, Jayson A. Childs

Theses and Dissertations (Comprehensive)

This study discusses the wave climate and potential littoral transport along the western shore of Prince Edward County approximately two hours east of Toronto along the northern shoreline of Lake Ontario. The limestone headlands and barrier bars of the western coast are exposed toward a southwesterly fetch of approximately 200 km that can produce large offshore wave heights of 2–5 m. The wave model STWAVE was used to transform a standard set of wave conditions developed from recent hindcast data to examine fair weather, storm and extreme conditions for five directions between south and west-northwest along the shore. The resulting …

Spawning-Related Movements Of Barred Sand Bass Paralabrax Nebulifer, In Southern California: Interpretations From Two Decades Of Historical Tag And Recapture Data, E. T. Jarvis, Christi Linardich, C. F. Valle

Biological Sciences Faculty Publications

During the 1960s and 1990s, the California Department of Fish and Game tagged 8,634 barred sand bass in southern California, and 972 fish (11%) were recaptured. Tag returns suggest barred sand bass are transient aggregate spawners that form spawning aggregations consisting of both resident and migrant individuals. Spawning residency at a historic spawning location was estimated by the frequency of returns over time; most same-year returns (82%, n  =  141) were recaptured within a 7 to 35-day period. The maximum recapture distance was 92 km. The average (± SD) non-spawning season recapture distance from peak spawning season tagging locations was …

Financial Securities Under Nonlinear Diffusion Asset Pricing Model, Andrey Vasilyev

Theses and Dissertations (Comprehensive)

In this thesis we investigate two pricing models for valuing financial derivatives. Both models are diffusion processes with a linear drift and nonlinear diffusion coefficient. The forward price process of these models is a martingale under an assumed risk-neutral measure and the transition probability densities are given in analytically closed form. Specifically, we study and calibrate two different families of models that are constructed based on a so-called diffusion canonical transformation. One family follows from the Ornstein-Uhlenbeck diffusion (the UOU family) and the other—from the Cox-Ingersoll-Ross process (the Confluent-U family).

The first part of the thesis considers single-asset and multi-asset …

Training Children Where They Learned Information: A Test Of Two Techniques, Justine Renner

Theses and Dissertations (Comprehensive)

Source-monitoring abilities are crucial skills for children’s social and cognitive development, thus, source-monitoring training (SMT) has the potential to benefit children in many practical settings. While some previous research reported that older (7- to 8-years-old) but not younger children (3- to 4-year-olds) benefitted from SMT (Poole & Lindsay, 2002), other studies have found training effects with younger children (Thierry & Spence, 2002; 2004). The current study examined younger and older children's source monitoring trainability by comparing the two different training used in these previous studies: training to a criterion versus a set amount of training. 158 children (aged 3-4 and …

Isolation And Characterization Of Ligands For The Goldfish Testicular Androgen Receptor From Kraft Mill Chemical Recovery Condensates, Philip David Scott

Theses and Dissertations (Comprehensive)

An investigation of cause was started in the 1990s at a bleached Kraft mill (BKM), located in Saint John NB, Canada. The 5th effect chemical recovery condensates waste stream (derived from wastewater generated during the pulping process) was identified as having the greatest potential for affecting mummichog (Fundulus heteroclitus), compared to the rest of the inmill waste streams. A solid phase extraction (SPE) protocol was utilized to isolate the causative chemicals in the condensate stream. Goldfish testicular androgen receptors (ARs) were exposed to five extracts: filter paper non-polar/polar, solid phase extraction nonpolar/polar, and residual condensates. The filter paper …

Carbon Dioxide Exchange In A Permafrost-Dominated Boreal Wetland In The Northwest Territories, Canada, Andrea J. Kenward

Theses and Dissertations (Comprehensive)

Northern boreal wetland complexes are substantial reservoirs for carbon and play a crucial role in both regional and global carbon budgets but they are showing significant signs of impact by climate change. This study examined the carbon dioxide flux of a high boreal wetland during the snowmelt and growing season of 2008 in Scotty Creek Basin, located near Fort Simpson (61°18'N, 121°18'W), Northwest Territories. This basin is not only responding to shifts in atmospheric temperatures, but it is also under additional pressure from increasing permafrost degradation. A dynamic closed-system chamber was used to monitor and quantify mid-day total respiration (R …

Microporous Organic Polymers: Synthesis And Post Synthetic Modifications, Phillip Andrew Kerneghan

Theses and Dissertations (Comprehensive)

Microporous solids are an important class of materials that have been studied extensively. Newer to this field are Microporous Organic Polymers (MOPs) which are networks constructed from smaller organic building blocks and exhibit large surface areas, small pore sizes and low densities. It is due to these characteristics that MOPs have attracted attention because of their potential use in applications such as catalysis, chemical separations and gas storage.

In this thesis is described the synthesis of two novel MOPs, the first of which being a network based on benzenediboronic acid and triptycene building blocks linked together by boronate esters. This …

Ancient Dna Analyses Exclude Humans As The Driving Force Behind Late Pleistocene Musk Ox (Ovibos Moschatus) Population Dynamics, Paula F. Campos, Eske Willerslev, Andrei Sher, Ludovic Orlando, Erik Axelsson, Alexei Tikhonov, Kim Aaris-Sorensen, Alex D. Greenwood, Ralf-Dietrich Kahlke, Pavel Kosintsev

Biological Sciences Faculty Publications

The causes of the late Pleistocene megafaunal extinctions are poorly understood. Different lines of evidence point to climate change, the arrival of humans, or a combination of these events as the trigger. Although many species went extinct, others, such as caribou and bison, survived to the present. The musk ox has an intermediate story: relatively abundant during the Pleistocene, it is now restricted to Greenland and the Arctic Archipelago. In this study, we use ancient DNA sequences, temporally unbiased summary statistics, and Bayesian analytical techniques to infer musk ox population dynamics throughout the late Pleistocene and Holocene. Our results reveal …

Taxing Inheritances, Taxing Estates, James R. Hines Jr.

Articles

This Article considers two aspects of converting the U.S. transfer tax system to one in which burdens are imposed on the basis of receipt rather than gift. The first aspect is the economic impact of distinguishing transfer tax liabilities by numbers of children in a family in addition to the total amount of transferred wealth. The second aspect is the nature of the event that triggers tax liability. Taxing on the basis of receipt raises complicated issues about generation-skipping transfers, transfers to trusts, and transfers that involve foreign as well as domestic parties, all of which are potentially influenced by …

Applying The “Contextual Integrity” Model Of Privacy To Personal Blogs In The Blogoshere, Frances Grodzinsky, Herman T. Tavani

School of Computer Science & Engineering Faculty Publications

In this paper, we analyze some controversial aspects of blogging and the blogosphere from the perspective of privacy. In particular, we focus on Helen Nissenbaum’s theory of privacy as “contextual integrity” and apply it to personal blogs, in general, and the case of the “Washingtonienne” blogger, in particular. We examine the question of whether personal blogs that are not password protected can be considered “normatively private contexts” according to Nissenbaum’s principles of privacy. We argue that they cannot. Using Nissenbaum’s original model, we conclude that privacy expectations for those who disclose personal information in such blogs are unrealistic. We also …

Should Individual Investors Use Technical Trading Rules To Attempt To Beat The Market?, Thomas S. Coe, Kittipong Laosethakul

WCBT Faculty Publications

Problem statement: Despite widespread academic acceptance of the Efficient Markets Hypothesis, some stock traders still use technical trading rules in an attempt to beat the market. Approach: This study looked at four trading rules, namely, the arithmetic moving average, the relative strength index, a stochastic oscillator and its moving average. These trading rules compare the relationship of current prices to past price patterns to generate a signal when to buy and sell stocks. The trading rules were tested over the years 2000-2009, a period of time that exhibited bull and bear markets, to determine if traders could actively …

Orthodox Jewish Women And Eligibility For The Parsonage Exemption, Jacob Lewin

Cardozo Journal of Equal Rights & Social Justice

The note examines the eligibility of Orthodox Jewish women for the parsonage exemption under Section 107 of the Internal Revenue Code, arguing that unordained women can qualify if they hold formal theological degrees, despite lacking formal ordination or certification. It critiques Michael Broyde’s proposal that functional roles alone suffice, asserting that requiring formal licensing or certification prevents abuse of the exemption while ensuring its purpose of supporting religious leadership is maintained.

Dynamical Theory Calculations Of Spin-Echo Resolved Grazing-Incidence Scattering From A Diffraction Grating, Rana Ashkar, P. Stonaha, A. L. Washington, V. R. Shah, M. R. Fitzsimmons, B. Maranville, C. F. Majkrzak, W. T. Lee, W. L. Schaich, Roger Pynn

Nebraska Center for Materials and Nanoscience: Faculty Publications

Neutrons scattered or reflected from a diffraction grating are subject to a periodic potential analogous to the potential experienced by electrons within a crystal. Hence, the wavefunction of the neutrons can be expanded in terms of Bloch waves and a dynamical theory can be applied to interpret the scattering phenomenon. In this paper, a dynamical theory is used to calculate the results of neutron spin-echo resolved grazing-incidence scattering (SERGIS) from a silicon diffraction grating with a rectangular profile. The calculations are compared with SERGIS measurements made on the same grating at two neutron sources: a pulsed source and a continuous …

Other-Centred Love: Diotima’S Lesson To Socrates, Colin A. Redmond

Theses

In this thesis I set out to determine the possible motivations in response to which Diotima agreed to teach Socrates the arts of love. In the process I develop a broader understanding of Diotima and her natural, feminine complexity. This understanding of Diotima suggests an interpretation of her teaching to show that, for all that can be said of love it is, importantly a re-orientation from self-centred interest to other-centred interest and it is this re-orientation which impacted on Socrates and by which he was persuaded.

Such an impact and its explanation offers a clear rationale for the changes which …

Racism, Eugenics, And Ernst Mayr’S Account Of Species, Ladelle Mcwhorter

Philosophy Faculty Publications

At his death at age one hundred in 2005, Ernst Mayr was hailed as the greatest evolutionary biologist of the twentieth century. His definition of species, published in 1942 in Systematics and the Origin of Species and known as the “biological species concept,” is familiar to every tenth grader: “Species are groups of interbreeding natural populations that are reproductively isolated from other such groups.” That definition, together with Mayr’s and Theodosius Dobzhansky’s theory of speciation, enabled the integration of modern genetics and Darwinian evolutionary theory. In this paper I will argue that it imported racism into the heart of modern …

Quantifying Individual Potential Contributions Of The Hybrid Sulfur Electrolyzer, John A. Staser, Maximilian B. Gorensek, John W. Weidner

Faculty Publications

The hybrid sulfur cycle has been investigated as a means to produce clean hydrogen efficiently on a large scale by first decomposing H₂SO₄ to SO₂, O₂, and H₂O and then electrochemically oxidizing SO₂ back to H₂SO₄ with the cogeneration of H₂. Thus far, it has been determined that the total cell potential for the hybrid sulfur electrolyzer is controlled mainly by water transport in the cell. Water is required at the anode to participate in the oxidation of SO₂ to H₂SO_{4 …}

This paper presents the design and implementation of a semantic web-based DMMS. Key lessons learned, technical and organizational issues encountered are summarized and directions for future research have been outlined. From a technical perspective, future research will need to explore the viability of tools specifically designed to facilitate the semantic annotation of …

An Efficient Electrochemical–Thermal Model For A Lithium-Ion Cell By Using The Proper Orthogonal Decomposition Method, Long Cai, Ralph E. White

Faculty Publications

The proper orthogonal decomposition method was applied to develop an efficient, reduced order electrochemical–thermal model for a lithium-ion cell. This model was validated for discharge simulations over a wide range of C rates and various cooling conditions of the cell. The reduced order model agrees well with the COMSOL model, a commercial finite element method solver, and requires times less computation time than the COMSOL model. The model predictions indicate that the discharge time or percent of capacity removed from the cell at an end of discharge voltage of 3.0 V depends on the rate of the discharge and heat …

Maximizing The Life Of A Lithium-Ion Cell By Optimization Of Charging Rates, Saeed Khaleghi Rahimian, Sean Rayman, Ralph E. White

Faculty Publications

Using a dynamic optimization method, the optimum charge currents as a function of cycle number during cycling for the lithium-ion cell are obtained. A single particle physics-based model, which includes capacity fade, was applied to simulate the cell performance under low earth-orbit (LEO) cycling conditions. Useful cell life is defined as the number of cycles before the end of discharge voltage drops below 3.0 V or the cell discharge capacity becomes less than 20% of the original discharge capacity. The simulated useful cell life can be increased by ∼29.28% by varying the charge current.

Theoretical Analysis Of Stresses In A Lithium Ion Cell, Sindhuja Renganathan, Godfrey Sikha, Shriram Santhanagopalan, Ralph E. White

Faculty Publications

A mathematical model to simulate the generation of mechanical stress during the discharge process in a dual porous insertion electrode cell sandwich comprised of lithium cobalt oxide and carbon is presented. The model attributes stress buildup within intercalation electrodes to two different aspects: changes in the lattice volume due to intercalation and phase transformation during the charge/discharge process. The model is used to predict the influence of cell design parameters such as thickness, porosity, and particle size of the electrodes on the magnitude of stress generation. The model developed in this study can be used to understand the mechanical degradation …
