Masquerade Detection On Mobile Devices, Swathi Nambiar Kadala Manikoth

Master's Projects

A masquerade is an attack where the attacker avoids detection by impersonating an authorized user of a system. In this research we consider the problem of masquerade detection on mobile devices. Our goal is to improve on previous work by considering more features and a wide variety of machine learning techniques. Our approach consists of verifying the authenticity of users based on individual features and combinations of features for all users to determine which features contribute the most to masquerade detection. Also, we determine which of the two approaches - the combination of features or using individual features has performed …

Analysis Of Periodicity In Botnets, Prathiba Nagarajan

Master's Projects

A botnet consists of a network of infected computers which are controlled re- motely via a command and control (C&C) server. A typical botnet requires frequent communication between the C&C server and the infected nodes. Previous approaches to detecting botnets have employed various machine learning techniques, based on features extracted from network tra c. In this research, we carefully analyze the pe- riodicity of tra c as a means for detecting a variety of botnets by applying machine learning to publicly available datasets.

Image Spam Detection, Aneri Chavda

On The Origin Of Energy: Metaphors And Manifestations As Resources For Conceptualizing And Measuring The Invisible, Imponderable, Benedikt Harrer

Faculty Publications

This article explores the origins of metaphorical language to describe energy by reviewing the historical development of the concept by physicists since the early 19th century. In addition to examples of historical and contemporary use of metaphors in academic writing, observable manifestations of energy are identified as the origin of energy “forms.” The historical- philosophical review and presentation of examples from contemporary physics literature contribute a disciplinary foundation to recent claims about the productiveness of physics learners’ use of metaphors and indicators to describe energy.

Faculty Response To Deselection In Academic Libraries: A Psycholinguistic Analysis, Ann Agee

Faculty and Staff Publications

Deselection is a necessary but politically sensitive part of an academic librarian's responsibilities. To provide an overview of the emotional dynamics involved in weeding an academic collection, this article analyzes editorials, articles, and book chapters chronicling faculty response to weeding from a psycholinguistic viewpoint. Using computer-based text analysis, these accounts are examined for the amount and type of emotional content they contain. These findings provide a template for what librarians can expect when beginning a deselection process and point to best practices for working effectively with faculty to create a robust and healthy collection.

In order to evaluate ease, efficacy, and comprehension of the forensic science kits by eScience Labs was completed while writing observations of the activities during and after completion; the lab manual learning objectives were compared to results of activities and two stopwatches took elapsed time of each activity to compare with the stated times in the kit manual. …

Kinetic Theory Of Dark Solitons With Tunable Friction, Hilary M. Hurst, Dimitry K. Efimkin, I. B. Spielman, Victor Galitski

Faculty Research, Scholarly, and Creative Activity

We study controllable friction in a system consisting of a dark soliton in a one-dimensional Bose-Einstein condensate coupled to a non-interacting Fermi gas. The fermions act as impurity atoms, not part of the original condensate, that scatter off of the soliton. We study semi-classical dynamics of the dark soliton, a particle-like object with negative mass, and calculate its friction coefficient. Surprisingly, it depends periodically on the ratio of interspecies (impurity-condensate) to intraspecies (condensate-condensate) interaction strengths. By tuning this ratio, one can access a regime where the friction coefficient vanishes. We develop a general theory of stochastic dynamics for negative mass …

Inside The Mind Of Mcmillen, Tina Duong

ART 108: Introduction to Games Studies

The paper discusses how Edmund McMillen created “The Binding of Isaac”. It goes into his inspirations, influences, and his background leading up to the game. It then describes the game, going into its mechanics, design, art and story and how each of these elements were unique and risky to put into an Indie game. I discussed how “The Binding of Isaac” brought in fresh, new elements that most mainstream games wouldn’t dare touch, and despite that “Binding of Isaac” accomplished amazing success. Then, I talk about how the game was initially made by a group of two people, and was …

The Hi Content Of Isolated Ultra-Diffuse Galaxies: A Sign Of Multiple Formation Mechanisms?, E. Papastergis, E. Adams, Aaron Romanowsky

Faculty Publications

We report on the results of radio observations in the 21 cm emission line of atomic hydrogen (HI) of four relatively isolated ultra-diffuse galaxies (UDGs): DGSAT I, R-127-1, M-161-1, and SECCO-dI-2. Our Effelsberg observations resulted in non-detections for the first three UDGs, and a clear detection for the last. DGSAT I, R-127-1, and M-161-1 are quiescent galaxies with gas fractions that are much lower than those of typical field galaxies of the same stellar mass. On the other hand, SECCO-dI-2 is a star forming gas-rich dwarf, similar to two other field UDGs that have literature HI data: SECCO-dI-1 and UGC …

Improving Livability Using Green And Active Modes: A Traffic Stress Level Analysis Of Transit, Bicycle, And Pedestrian Access And Mobility, Maaza C. Mekuria, Bruce Appleyard, Hilary Nixon

Mineta Transportation Institute

Understanding the relative attractiveness of alternatives to driving is vitally important toward lowering driving rates and, by extension, vehicle miles traveled (VMT), traffic congestion, greenhouse gas (GHG) emissions, etc. The relative effectiveness of automobile alternatives (i.e., buses, bicycling, and walking) depends on how well streets are designed to work for these respective modes in terms of safety, comfort and cost, which can sometimes pit their relative effectiveness against each other. In this report, the level of traffic stress (LTS) criteria previously developed by two of the authors was used to determine how the streets functioned for these auto alternative modes. …

Generic Online Learning For Partial Visible & Dynamic Environment With Delayed Feedback, Behrooz Shahriari

Master's Projects

Reinforcement learning (RL) has been applied to robotics and many other domains which a system must learn in real-time and interact with a dynamic environment. In most studies the state-action space that is the key part of RL is predefined. Integration of RL with deep learning method has however taken a tremendous leap forward to solve novel challenging problems such as mastering a board game of Go. The surrounding environment to the agent may not be fully visible, the environment can change over time, and the feedbacks that agent receives for its actions can have a fluctuating delay. In this …

Improving Energy Efficiency For Iot Communications In 5g Networks, Gary Su

Master's Projects

Increase in number of Internet of Things (IoT) devices is quickly changing how mobile networks are being used by shifting more usage to uplink transmissions rather than downlink transmissions. Currently, mobile network uplinks utilize Single Carrier Frequency Division Multiple Access (SC-FDMA) schemes due to the low Peak to Average Power Ratio (PAPR) when compared to Orthogonal Frequency Division Multiple Access (OFDMA). In an IoT perspective, power ratios are highly important in effective battery usage since devices are typically resource-constrained. Fifth Generation (5G) mobile networks are believed to be the future standard network that will handle the influx of IoT device …

Multi-Valued Sequences Generated By Power Residue Symbols Over Odd Characteristic Fields, Begum Nasima, Yasuyuki Nogami, Satoshi Uehara, Robert Morelos-Zaragoza

Faculty Publications

This paper proposes a new approach for generating pseudo random multi-valued (including binary-valued) sequences. The approach uses a primitive polynomial over an odd characteristic prime field $\f{p}$, where p is an odd prime number. Then, for the maximum length sequence of vectors generated by the primitive polynomial, the trace function is used for mapping these vectors to scalars as elements in the prime field. Power residue symbol (Legendre symbol in binary case) is applied to translate the scalars to k-value scalars, where k is a prime factor of p-1. Finally, a pseudo random k-value sequence is obtained. Some important properties …
