Peer-To-Peer Botnets: Analysis And Detection, Jeet Morparia

Master's Projects

Attacks such as spamming, distributed denial of service and phishing have become commonplace on the Internet. In the past, attackers would use high bandwidth Internet connection servers to accomplish their tasks. Since desktop users today have high-speed Internet connections, attackers infect users’ desktops and harness their computing power to perform malicious activities over the Internet. As attackers develop new methods to attack from distributed locations as well as avoid being detected, there is a need to develop efficient methods to detect and mitigate this epidemic of infection of hosts on the network. In this project, we aim to analyze the …

Accelerometer Based Motion Gestures For Mobile Devices, Neel Parikh

Master's Projects

Many smart phones today use tiny sensors called accelerometers to provide enhanced user interface controls. Accelerometers measure the linear acceleration in the x, y, z directions based on the movement of the phone. These sensors basically reduce the need of dedicated navigation and function keys on the mobile device. Accelerometer based mobile devices use this principle for creating applications like games, controlling the orientation of the display screen, etc. The goal of this project is to extend the WebKit browser interface of Google’s mobile development platform called ‘Android’ by creating accelerometer based motion features like shake feature, orientation of images, …

Code Obfuscation And Virus Detection, Ashwini Venkatesan

Master's Projects

Typically, computer viruses and other malware are detected by searching for a string of bits which is found in the virus or malware. Such a string can be viewed as a “fingerprint” of the virus. These “fingerprints” are not generally unique; however they can be used to make rapid malware scanning feasible. This fingerprint is often called a signature and the technique of detecting viruses using signatures is known as signaturebased detection [8]. Today, virus writers often camouflage their viruses by using code obfuscation techniques in an effort to defeat signature-based detection schemes. So-called metamorphic viruses are viruses in which …

Constructing An Ethic Of Care In Teacher Education: Narrative As Pedagogy Toward Care, Colette Rabin

Faculty Publications

Teacher educators have a civic responsibility to prepare novice teachers to foster relationships across cultural, racial, and socioeconomic divides. Care ethics acknowledges this imperative. This study explores how to cultivate the knowledge, skills and dispositions associated with constructing a caring stance toward the work of teaching. Data come from two preservice teacher education courses. A cluster of course activities sought to foster novice teachers’ core skills for a caring stance. In particular, one assignment, an ethical dilemma case, gave the novice teachers the opportunity to write a narrative about practice and consider any potential moral implications. Since narrative methodology accounts …

Forcing Mechanisms For Washoe Zephyr - A Daytime Downslope Wind Phenomenon In The Great Basin East Of The Sierra Nevada, Shiyuan Zhong, Ju Li, Craig Clements, Stephan Dewekker, Xindi Bian

Faculty Publications, Meteorology and Climate Science

This paper investigates the formation mechanisms for a local wind phenomenon known as Washoe Zephyr that occurs frequently in the lee of the Sierra Nevada. Unlike the typical thermally driven slope flows with upslope wind during daytime and downslope at night, the Washoe Zephyr winds blow down the lee slopes of the Sierra Nevada in the afternoon against the local pressure gradient. Long-term hourly surface wind data from several stations on the eastern slope of the Sierra Nevada and rawinsonde sounding data in the region are analyzed and numerical simulations are performed to test the suggested hypotheses on the formation …

Evidence Contrary To The Statistical View Of Boosting, David Mease, A. Wyner

Faculty Publications

The statistical perspective on boosting algorithms focuses on optimization, drawing parallels with maximum likelihood estimation for logistic regression. In this paper we present empirical evidence that raises questions about this view. Although the statistical perspective provides a theoretical framework within which it is possible to derive theorems and create new algorithms in general contexts, we show that there remain many unanswered important questions. Furthermore, we provide examples that reveal crucial flaws in the many practical suggestions and new methods that are derived from the statistical view. We perform carefully designed experiments using simple simulation models to illustrate some of these …

Purpose Machines, Douglas Edric Stanley

SWITCH

This article explores how machines can be designed to have purpose - not just to follow instructions, but to react, adapt, and change based on their environment. The author compares early ideas from cybernetics and computer science with modern technologies, showing how machines today can be flexible, creative, and open-ended. He also questions the idea that artists can “re-purpose” machines, since machines are already made to be re-used.

Testing The Nature Of S0 Galaxies Using Planetary Nebula Kinematics In Ngc 1023, E. Noordermeer, M. R. Merrifield, L. Coccato, M. Arnaboldi, M. Capaccioli, N. G. Douglas, K. C. Freeman, O. Gerhard, K. Kuijken, F. De Lorenzi, N. R. Napolitano, Aaron J. Romanowsky

Faculty Publications

We investigate the manner in which lenticular galaxies are formed by studying their stellar kinematics: an S0 formed from a fading spiral galaxy should display similar cold outer disc kinematics to its progenitor, while an S0 formed in a minor merger should be more dominated by random motions. In a pilot study, an attempt to distinguish between these scenarios, we have measured the planetary nebula (PN) kinematics of the nearby S0 system NGC 1023. Using the Planetary Nebula Spectrograph, we have detected and measured the line-of-sight velocities of 204 candidate planetary nebulae (PNe) in the field of this galaxy. Out …

Stochastic Hard-Sphere Dynamics For Hydrodynamics Of Non-Ideal Fluids, Alejandro Garcia, A. Donev, B. J. Alder

Faculty Publications

A novel stochastic fluid model is proposed with a nonideal structure factor consistent with compressibility, and adjustable transport coefficients. This stochastic hard sphere dynamics (SHSD) algorithm is a modification of the direct simulation Monte Carlo algorithm and has several computational advantages over event-driven hard-sphere molecular dynamics. Surprisingly, SHSD results in an equation of state and a pair correlation function identical to that of a deterministic Hamiltonian system of penetrable spheres interacting with linear core pair potentials. The fluctuating hydrodynamic behavior of the SHSD fluid is verified for the Brownian motion of a nanoparticle suspended in a compressible solvent.

Women Disunited : Margaret Atwood's The Handmaid's Tale As A Critique Of Feminism, Alanna A. Callaway

Master's Theses

While there is plenty of traditional feminist critique of male power structures in Atwood's works, and particularly in The Handmaid's Tale, this thesis argues that the power structure of Gilead (the biblically-inflected nation Atwood imagines) also critiques the feminine roles that support and enable the repression of other women. Placing the novel in the contexts of Atwood's career, feminism, and dystopian literature, provides a fuller understanding of how the novel functions as an expression of the disunity of women.

Thus, this thesis turns the focus of The Handmaid's Tale from the consequences of patriarchal control and "traditional" misogyny, to the …

Exceptionally Preserved Jellyfishes From The Middle Cambrian, Paulyn Cartwright, Susan L. Halgedahl, Jonathan R. Hendricks, Richard D. Jarrard, Antonio C. Marques, Allen G. Collins, Bruce S. Lieberman

Faculty Publications

Cnidarians represent an early diverging animal group and thus insight into their origin and diversification is key to understanding metazoan evolution. Further, cnidarian jellyfish comprise an important component of modern marine planktonic ecosystems. Here we report on exceptionally preserved cnidarian jellyfish fossils from the Middle Cambrian (~505 million years old) Marjum Formation of Utah. These are the first described Cambrian jellyfish fossils to display exquisite preservation of soft part anatomy including detailed features of structures interpreted as trailing tentacles and subumbrellar and exumbrellar surfaces. If the interpretation of these preserved characters is correct, their presence is diagnostic of modern jellyfish …

Information Literacy For Branch Campuses And Branch Libraries, James Hooks, Carl Rahkonen, Chris Clouser, Kelly Heider, Rena Fowler

Library Philosophy and Practice (e-journal)

Although information literacy objectives are a constant, teaching methods and pedagogy must be structured differently in different teaching-learning environments. The Libraries of Indiana University of Pennsylvania (IUP) created a new model of library instruction for its branch libraries and branch campuses, based on the embedded or college librarian model. Librarians for music, science, education, and the IUP Northpointe campus have been integrated into the instruction and curricular activities of those locations, some of which include distance education programs. While this model has logistical and political challenges, it has proved beneficial in improving information literacy for both faculty and students, and …

Implementing An Embedded Information Literacy Program At The University Level: Best Practices, Ann Agee

Faculty and Staff Publications

Information literacy is the ability of individuals "to recognize when information is needed and have the ability to locate, evaluate, and use effectively the needed information" (American Library Association, 1989, para. 3). At San Jose State University (SJSU), information literacy has been traditionally taught through one-shot, 50-minute lectures delivered by university librarians to students enrolled in a select few undergraduate courses. This method of instruction has proven to be neither sustainable nor effective. The lectures are not tailored by discipline and students might receive the same lecture several times while completing their lower-division coursework. SJSU wants to replace this format …

Faculty Publications, Meteorology and Climate Science

[1] Simulations from eleven coupled chemistry-climate models (CCMs) employing nearly identical forcings have been used to project the evolution of stratospheric ozone throughout the 21st century. The model-to-model agreement in projected temperature trends is good, and all CCMs predict continued, global mean cooling of the stratosphere over the next 5 decades, increasing from around 0.25 K/decade at 50 hPa to around 1 K/decade at 1 hPa under the Intergovernmental Panel on Climate Change (IPCC) Special Report on Emissions Scenarios (SRES) A1B scenario. In general, the simulated ozone evolution is mainly determined by decreases in halogen concentrations and continued cooling of …

Bedrock Channel Geometry Along An Orographic Rainfall Gradient In The Upper Marsyandi River Valley In Central Nepal, William Craddock, Douglas Burbank, Bodo Bookhagen, Emmanuel Gabet

Faculty Publications

Pronounced rainfall gradients combined with spatially uniform exhumation of rocks at Quaternary timescales and uniform rock strength make the upper Marsyandi River valley in central Nepal a useful natural laboratory in which to explore variations in bedrock channel width. We focus on small catchments (0.6–12.4 km2) along a more than tenfold gradient in monsoon rainfall. Rainfall data are gathered from a dense weather network and calibrated satellite observations, the pattern of Quaternary exhumation is inferred from apatite fission track cooling ages, and rock compressive strength is measured in the field. Bedrock channel widths, surveyed at high scour indicators, scale as …
