Insights Into Malware Detection And Prevention On Mobile Phones, Qiang Yan, Yingjiu Li, Tieyan Li, Robert H. Deng

Research Collection School Of Computing and Information Systems

The malware threat for mobile phones is expected to increase with the functionality enhancement of mobile phones. This threat is exacerbated with the surge in population of smart phones instilled with stable Internet access which provides attractive targets for malware developers. Prior research on malware protection has focused on avoiding the negative impact of the functionality limitations of mobile phones to keep the performance cost within the limitations of mobile phones. Being different, this paper investigates the positive impact of these limitations on suppressing the development of mobile malware. We study the state-of-the-art mobile malware, as well as the progress …

Denial-Of-Service Attacks On Host-Based Generic Unpackers, Limin Liu, Jiang Ming, Zhi Wang, Debin Gao, Chunfu Jia

Research Collection School Of Computing and Information Systems

With the advance of packing techniques, a few generic and automatic unpackers have been proposed. These unpackers are designed to automatically unpack packed binaries without specific knowledge of the packing techniques used. In this paper, we present an automatic packer with which packed malware forges spurious unpacking behaviors that lead to a denial-of-service attack on host-based generic unpackers. We present the design, implementation, and evaluation of the proposed packer and malware produced using the proposed packer, and show the success of denial-of-service attacks on host-based generic unpackers.

On Strategies For Imbalanced Text Classification Using Svm: A Comparative Study, Aixin Sun, Ee Peng Lim, Ying Liu

Research Collection School Of Computing and Information Systems

Many real-world text classification tasks involve imbalanced training examples. The strategies proposed to address the imbalanced classification (e.g., resampling, instance weighting), however, have not been systematically evaluated in the text domain. In this paper, we conduct a comparative study on the effectiveness of these strategies in the context of imbalanced text classification using Support Vector Machines (SVM) classifier. SVM is the interest in this study for its good classification accuracy reported in many text classification tasks. We propose a taxonomy to organize all proposed strategies following the training and the test phases in text classification tasks. Based on the taxonomy, …

Exempting High-Level Employees And Small Employers From Legislation Invalidating Predispute Employment Arbitration Agreements, E. Gary Spitko

Faculty Publications

On February 12, 2009, lawmakers in the U.S.House of Representatives introduced the "Arbitration Fairness Act of 2009. " This bill, if enacted, will invalidate any predispute arbitration agreement between an employer and its employee. Last year, the 110th Congress considered the narrower "Preservation of Civil Rights Protections Act of 2008, " which would have invalidated such predispute arbitration agreements if they required "arbitration of a dispute arising under" federal civil rights laws. This Article explores how best to structure any such invalidation of predispute employment arbitration agreements, both in light of the rationales for and against regulation of the employment …

A Vector Matrix Real Time Backpropagation Algorithm For Recurrent Neural Networks That Approximate Multi-Valued Periodic Functions, Peter Stubberud

Electrical & Computer Engineering Faculty Research

Unlike feedforward neural networks (FFNN) which can act as universal function approximators, recursive, or recurrent, neural networks can act as universal approximators for multi-valued functions. In this paper, a real time recursive backpropagation (RTRBP) algorithm in a vector matrix form is developed for a two-layer globally recursive neural network that has multiple delays in its feedback path. This algorithm has been evaluated on two GRNNs that approximate both an analytic and nonanalytic periodic multi-valued function that a feedforward neural network is not capable of approximating.

Mountain Monitor-3rd Quarter 2009, Brookings Mountain West

Mountain Monitor Quarterly

Nationwide, the recession is technically over. Or at least that is the view of most economists. They note that real U.S. gross domestic product (GDP) finally expanded in the third quarter of 2009, growing at a 2.8 percent annual rate after four consecutive quarters of contraction. They point to a significant slowing of job losses in November, rising housing prices, and a slight downtick in unemployment as other positive signs. Their conclusion: Economic recovery is at last underway. And yet, the pace of renewal seems tentative and its geography patchy. Most notably, the aggregate national story of recovery and expansion …

Social Networking: Is It Another Stage In The Evolution Of Communication And Does It Affect The Way We Think About Problem Solving And Communicating?, Sandy L. Robinson

Communication & Leadership Dissertations and Theses

This thesis explores whether participants in online social networking sites differ from non-participants in their approach to problem solving or in their attitudes about their interactions with their own social networks. Walter Ong (1982) determined that people’s thinking changed with different media usage, particularly from oral to script, script to print, and print to electronic. This research examines problem solving and attitudes about interactions with social networks as two criteria for exploring how people think. In a review of the literature, the thesis explores the theory of media ecology, which expands on the work of McLuhan (1967) and Ong (1982), …

Constructing A Magneto-Optical Trap For Cold Atom Trapping, Eric S. Muckley

Physics

A magneto-optical trap, or MOT, is a device that traps atoms between three pairs of opposing perpendicular laser beams for cooling the atoms to temperatures near absolute zero. The MOT uses Doppler cooling and a magnetic quadrupole field to trap the atoms; in our case, Rb87 atoms. In the future, the MOT will be used in experiments pertaining to the advancement of quantum computing. In this paper, I explain some of the processes required for construction and operation of the MOT.

Dr. Keller developed a test, known as the Greenhouse Effect Concept Inventory (GECI), designed to measure a student’s understanding of the greenhouse effect. A central goal of this project is to investigate the effectiveness of this concept inventory at measuring differences in student knowledge of the greenhouse effect. In addition to the Cal Poly student population that participated in this research, we will be looking at the population …

Developing A B-Jet Tagging Algorithm For Alice: Lessons From Cdf, Paul Chester-John Carlson

Physics

This paper compares the detectors and algorithms developed and used at both A Large Ion Collider Experiment (ALICE) and the Collider Detector at Fermilab (CDF). We found that the detectors share many similarities in data collection and analysis methods and that by adapting algorithms that have been tested and used at CDF, ALICE could augment its existing algorithms. The algorithms formed from this adaptation will help ALICE isolate b-jets quickly and explore the quark-gluon plasma, ultimately expanding our understanding of the strong nuclear force and its role in the evolution of our universe.
