Learning Author’S Writing Pattern System By Automata, Qun Yu
Learning Author’S Writing Pattern System By Automata, Qun Yu
Master's Projects
The purpose of the report is to document our project’s theory, implementation and test results. The project works on an automata-based learning system which models authors’ writing characters with automatons. Since there were pervious works done by Dr. T.Y. Lin and Ms. S.X. Zhang, we continue on ALERGIA algorithm analysis and initial common pattern study in this project. Although every author has his/her own writing style, such as sentence length and word frequency etc, there are always some similarities in writing style. We hypothesize that common strings fogged the expected test result, just like the noise in radio wave. This …

Improving Performance Of Bittorrent Network Through Incentive Mechanism, Mingzhe Li
Master's Projects
Content Distribution via Internet has become increasingly popular right now. Compared with centralized file distribution system using FTP and HTTP protocols, P2P (Peer to Peer) is more cost-effective. Furthermore, it could help save on bandwidth costs and to handle pick demands. Among many P2P protocols, BitTorrent is one of the most popular protocols right now. The BitTorrent network uses tit-for-tat as a method of seeking Pareto efficiency. However, seeders who contribute more to BitTorrent network than leechers are not incentivized to stay online and upload to others. This paper discusses an incentive mechanism which rewards seeder, who stays in a …

Efficient Unfolding Pattern Recognition In Single Molecule Force Spectroscopy Data, Bill Andreopoulos, Dirk Labudde
Efficient Unfolding Pattern Recognition In Single Molecule Force Spectroscopy Data, Bill Andreopoulos, Dirk Labudde
Faculty Publications, Computer Science
BackgroundSingle-molecule force spectroscopy (SMFS) is a technique that measures the force necessary to unfold a protein. SMFS experiments generate Force-Distance (F-D) curves. A statistical analysis of a set of F-D curves reveals different unfolding pathways. Information on protein structure, conformation, functional states, and inter- and intra-molecular interactions can be derived.ResultsIn the present work, we propose a pattern recognition algorithm and apply our algorithm to datasets from SMFS experiments on the membrane protein bacterioRhodopsin (bR). We discuss the unfolding pathways found in bR, which are characterised by main peaks and side peaks. A main peak is the result of the pairwise …

Making Connections Between Science And Equity: A Motivation To Teach Science In Elementary Grades, Grinell Smith, Colette Rabin
Faculty Publications
Teacher quality is among the strongest correlates of student outcomes. However, only about a quarter of the nation’s elementary teachers consider themselves qualified to teach science. In this descriptive and exploratory study, we investigated whether helping pre-service teacher candidates explore connections between science and issues of equity, particularly around sustainability issues, could help them see the importance of teaching science to their students more often. Qualitative and quantitative data were collected from 59 students enrolled in revised science methods courses at a large public university. Our findings suggest that positioning science instruction thusly was perceived as a strong motivator to …
Thermodynamics Of The Antiferromagnetic Heisenberg Model On The Checkerboard Lattice, Ehsan Khatami, Maros Rigol
Thermodynamics Of The Antiferromagnetic Heisenberg Model On The Checkerboard Lattice, Ehsan Khatami, Maros Rigol
Faculty Publications
Employing numerical linked-cluster expansions (NLCEs) along with exact diagonalizations of finite clusters with periodic boundary condition, we study the energy, specific heat, entropy, and various susceptibilities of the antiferromagnetic Heisenberg model on the checkerboard lattice. NLCEs, combined with extrapolation techniques, allow us to access temperatures much lower than those accessible to exact diagonalization and other series expansions. We show that the high-temperature peak in specific heat decreases as the frustration increases, consistent with the large amount of unquenched entropy in the region around maximum classical frustration, where the nearest-neighbor and next-nearest-neighbor exchange interactions (J and J′, respectively) have the same …
Dynamic Code Checksum Generator, Ashish Sharma
Dynamic Code Checksum Generator, Ashish Sharma
Master's Projects
A checksum (i.e., a cryptographic hash) of a file can be used as an integrity check, if an attacker tries to change the code in an executable file, a checksum can be used to detect the tampering. While it is easy to compute a checksum for any static file, it is possible for an attacker to tamper with an executable file as it is being loaded into memory, or after it has been loaded. Therefore, it would be more useful to checksum an executable file dynamically only after the file has been loaded into memory. However, checksumming dynamic code is …

Substitution Cipher With NonPrefix Codes, Rashmi Bangalore Muralidhar
Master's Projects
Substitution ciphers normally use prefix free codes there is no code word which is the prefix of some other code word. Prefix free codes are used for encryption because it makes the decryption process easier at the receiver's end.
In this project, we study the feasibility of substitution ciphers with nonprefix codes. The advantage of using nonprefix codes is that extracting statistical information is more difficult. However, the ciphertext is nontrivial to decrypt.
We present a dynamic programming technique for decryption and verify that the plaintext can be recovered. This shows that substitution ciphers with nonprefix codes are feasible. …

Recipe Suggestion Tool, Sakuntala Padmapriya Gangaraju
Master's Projects
ABSTRACT
There is currently a great need for a tool to search cooking recipes based on ingredients. Current search engines do not provide this feature. Most of the recipe search results in current websites are not efficiently clustered based on relevance or categories resulting in a user getting lost in the huge search results presented.
Clustering in information retrieval is used for higher efficiency and better presentation of information to the user. Clustering puts similar documents in the same cluster. If a document is relevant to a query, then the documents in the same cluster are also relevant.
The goal …

Similarity Tests For Metamorphic Virus Detection, Mahim Patel
Similarity Tests For Metamorphic Virus Detection, Mahim Patel
Master's Projects
A metamorphic computer virus generates copies of itself using code morphing techniques. A new virus has the same functionality as the parent but it has a different internal structure. The goal of the metamorphic virus writer is to produce viral copies that have no common signature. If the viral copies are sufficiently different, they can evade signature detection, which is the most widely-used anti-virus technique.
In previous research, hidden Markov models (HMMs) have been used to detect some metamorphic viruses. However, recent research has shown that it is possible for carefully designed metamorphic viruses to evade HMM-based detection.
In this …

Robust Watermarking Using Hidden Markov Models, Mausami Mungale
Master's Projects
Software piracy is the unauthorized copying or distribution of software. It is a growing problem that results in annual losses in the billions of dollars. Prevention is a difficult problem since digital documents are easy to copy and distribute. Watermarking is a possible defense against software piracy. A software watermark consists of information embedded in the software, which allows it to be identified. A watermark can act as a deterrent to unauthorized copying, since it can be used to provide evidence for legal action against those responsible for piracy.
In this project, we present a novel software watermarking scheme that …
Improving Molecular Fingerprint Similarity Via Enhanced Folding, Victor Chen
Improving Molecular Fingerprint Similarity Via Enhanced Folding, Victor Chen
Master's Projects
Drug discovery depends on scientists finding similarity in molecular fingerprints to the drug target. A new way to improve the accuracy of molecular fingerprint folding is presented. The goal is to alleviate a growing challenge due to excessively long fingerprints. This improved method generates a new shorter fingerprint that is more accurate than the basic folded fingerprint. Information gathered during preprocessing is used to determine an optimal attribute order. The most commonly used blocks of bits can then be organized and used to generate a new improved fingerprint for more optimal folding. We thenapply the widely usedTanimoto similarity search algorithm …

Metamorphic Detection Via Emulation, Sushant Priyadarshi
Master's Projects
In parallel with improvements in anti-virus technologies, computer virus writers have developed innovative viruses that are challenging to detect. Metamorphic viruses change their appearance from one generation to another by using various code obfuscation techniques. Today, signature detection is the most common method used in anti-virus products, but well designed metamorphic viruses cannot be detected using signatures. Hence, there is a need for a more robust anti-virus technology.
To counter metamorphic virus, a very successful tool based on hidden Markov models (HMM) has been previously developed. This tool was able to detect all hacker produced metamorphic viruses on which it …
