San Francisco's Embaradero Promenade: An In-Depth Look At How Design Elements Along The Waterfront Affect User Behavior, Jacqueline Vance
Master's Projects
This research project will observe user behavior at three sites along San Francisco’s Embarcadero Promenade in an attempt to better understand how urban design elements (e.g. seating or public art) can positively or negatively affect how people use a public space. The specific question that this research will attempt to address is: What aspects of physical design in three key areas along the Embarcadero Promenade influence user behavior within this linear public space and how is that behavior positively or negatively affected? Recommendations will also be provided, suggesting possible opportunities to improve the Embarcadero Promenade as a successful public space.

Hidden Markov Models For Malware Classification, Chinmayee Annachhatre
Master's Projects
Malware is a software which is developed for malicious intent. Malware is a rapidly evolving threat to the computing community. Although many techniques for malware classification have been proposed, there is still the lack of a comprehensible and useful taxonomy to classify malware samples. Previous research has shown that hidden Markov model (HMM) analysis is useful for detecting certain types of malware. In this research, we consider the related problem of malware classification based on HMMs. We train HMMs for a variety of malware generators and a variety of compilers. More than 9000 malware samples are then scored against each …
Higher Order Pwm For Modeling Transcription Factor Binding Sites, Dhivya Srinivasan
Higher Order Pwm For Modeling Transcription Factor Binding Sites, Dhivya Srinivasan
Master's Projects
Traditional Position Weight Matrices (PWMs) that are used to model Transcription Factor Binding Sites (TFBS) assume independence among different positions in the binding site. In reality, this may not necessarily be the case. A better way to model TFBS is to consider the distribution of dinucleotides or trinucleotides instead of just mononucleotides, thus taking neighboring nucleotides into account. We can therefore, extend the single nucleotide PWM to a dinucleotide PWM or an even higher-order PWM to correctly estimate the dependencies among the nucleotides in a given sequence. The purpose of this project is to develop an algorithm to implement higher-order …
Compression-Based Analysis Of Metamorphic Malware, Jared Lee
Compression-Based Analysis Of Metamorphic Malware, Jared Lee
Master's Projects
Recent work has presented a technique based on structural entropy measurement as an effective way to detect metamorphic malware. The technique uses two steps, file segmentation and sequence comparison, to calculate file similarity. In another previous work, it was observed that similar malware have similar measures of Kolmogorov complexity. A proposed method of estimating Kolmogorov complexity was to calculate the compression ratio of a given malware which could then be used to cluster the malicious software. Malware detection has also been attempted through the use of adaptive data compression and showed promising results. In this paper, we attempt to combine …

Metamorphic Detection Using Singular Value Decomposition, Ranjith Kumar Jidigam
Master's Projects
Metamorphic malware changes its internal structure with each infection, while maintaining its original functionality. Such malware can be difficult to detect using static techniques, since there may be no common signature across infections. In this research we apply a score based on Singular Value Decomposition (SVD) to the problem of metamorphic detection. SVD is a linear algebraic technique which is applicable to a wide range of problems, including facial recognition. Previous research has shown that a similar facial recognition technique yields good results when applied to metamorphic malware detection. We present experimental results and we analyze the effectiveness and efficiency …

Pattern Discovery Of Sequential Symbolic Data Using Automata With An Application To Author Identification, Nikhil Kalantri
Pattern Discovery Of Sequential Symbolic Data Using Automata With An Application To Author Identification, Nikhil Kalantri
Master's Projects
Author Identification is the process of identifying a piece of text to ascertain if it has an inherent writing style or pattern based on a certain author. Almost all literary books can be accredited to a certain author since it has been signed. However, there also exist a plethora of unfinished books or manuscripts that could be attributed to a range of possible authors. For example, William Shakespeare has written many plays that have not been signed by him. In order to assess the importance of such texts that do not bear the authors signature, it could be vital to …

Master's Projects
Search engine is a very useful tool for almost everyone nowadays. People use search engine for the purpose of searching about their personal finance, restaurants, electronic products, and travel information, to name a few. As helpful as search engines are in terms of providing information, they can also manipulate people behaviors because most people trust online information without a doubt. Furthermore, ordinary users usually only pay attention the highest-ranking pages from the search results. Knowing this predictable user behavior, search engine providers such as Google and Yahoo take advantage and use it as a tool for them to generate profit. …

Cloud Storage Performance And Security Analysis With Hadoop And Gridftp, Wei-Li Liu
Master's Projects
Even though cloud server has been around for a few years, most of the web hosts today have not converted to cloud yet. If the purpose of the cloud server is distributing and storing files on the internet, FTP servers were much earlier than the cloud. FTP server is sufficient to distribute content on the internet. Therefore, is it worth to shift from FTP server to cloud server? The cloud storage provider declares high durability and availability for their users, and the ability to scale up for more storage space easily could save users tons of money. However, does it …
Application Of Secretary Algorithm To Dynamic Load Balancing In User-Space On Multicore Systems, Kyoung-Hwan Yun
Application Of Secretary Algorithm To Dynamic Load Balancing In User-Space On Multicore Systems, Kyoung-Hwan Yun
Master's Projects
In recent years, multicore processors have been so prevalent in many types of
systems and are now widely used even in commodities for a wide range of applications.
Although multicore processors are clearly a popular hardware solution to problems that
were not possible with traditional single-core processors, taking advantage of them are
inevitably met by software challenges. As Amdahl’s law puts it, the performance gain is
limited by the percentage of the software that cannot be run in parallel on multiple cores.
Even when an application is “embarrassingly” parallelized by a careful design of
algorithm and implementation, load balancing of …

Metamorphic Code Generation From Llvm Ir Bytecode, Teja Tamboli
Metamorphic Code Generation From Llvm Ir Bytecode, Teja Tamboli
Master's Projects
Metamorphic software changes its internal structure across generations with its functionality remaining unchanged. Metamorphism has been employed by malware writers as a means of evading signature detection and other advanced detection strate- gies. However, code morphing also has potential security benefits, since it increases the “genetic diversity” of software. In this research, we have created a metamorphic code generator within the LLVM compiler framework. LLVM is a three-phase compiler that supports multiple source languages and target architectures. It uses a common intermediate representation (IR) bytecode in its optimizer. Consequently, any supported high-level programming language can be transformed to this IR …
Automated Rtl Generator, Rohit Kulkarni
Automated Rtl Generator, Rohit Kulkarni
Master's Projects
Code generation is a vast topic and has been discussed and implemented for quite a while now. It has been also been a topic of debate as to what is an ideal code generator and how an ideal code generator can be created. The biggest challenge while creating a code generator is to maintain a balance between the amount of freedom given to the user and the restrictions imposed on the code generated. These two seemed to be very conflicting requirements while designing the Automated RTL Code Generator. If the code generator tries to be rigid and sticks to well-defined …

Using Social Networks For Assessing Company Sales And Marketing Programs, Vance Tomchalk
Master's Projects
During the course of an extended sales period for a company’s given product line, there are many events that affect the success of its sales. Some of these events include economic downturns, unforeseen shortages and delays that effect the supply chain for the product, and product quality issues that change the perception of the product as a safe and cost-effective choice. In many instances, these events can be tracked by analyzing the signals and messaging present in the social networking media. This analysis requires careful consideration, which the metrics provided by software tools and algorithms lend considerable aid.

Http Attack Detection Using N-Gram Analysis, Adityaram Oza
Master's Projects
Previous research has shown that byte level analysis of HTTP traffic offers a practical solution to the problem of network intrusion detection and traffic analysis. Such an approach does not require any knowledge of applications running on web servers or any pre-processing of incoming data. In this project, we apply three n- gram based techniques to the problem of HTTP attack detection. The goal of such techniques is to provide a first line of defense by filtering out the vast majority of benign HTTP traffic. We analyze our techniques in terms of accuracy of attack detection and performance. We show …
User Profiling In Gui Based Windows Systems For Intrusion Detection, Arshi Agrawal
User Profiling In Gui Based Windows Systems For Intrusion Detection, Arshi Agrawal
Master's Projects
Intrusion detection is the process of identifying any unauthorized access to a sys- tem. This process inspects user behavior to identify any possible attack or intrusion. There exists two type of intrusion detection systems (IDSs): signature-based IDS and anomaly-based IDS. This project concentrates on anomaly-based intrusion detection technique. This technique is based on the deviation of intruder’s actions from the authenticated user’s actions. Much previous research has focused on the deviation of command line input in UNIX systems. However, these techniques fail to detect attacks on modern GUI- based systems, where typical user activities include mouse movements and keystrokes. Our …
