Data Mining And Data Warehouse ------ Maximal Simplex Method, Madhuri Gollu

Master's Projects

Association Rule Mining is a widely used method for finding interesting relationships from large data sets. The challenge here is how to swiftly and accurately discover association rules from large data sets. To achieve this, this paper will (1) build a data warehouse system that simulates the secondary storage and represents a database by bit patterns, and (2) implement a new geometric algorithm to find association rules, called Maximal Simplex Algorithm. The data warehouse consists of very long bit columns. Each column is an item or an attribute value pair and a row represents a transaction or a tuple in …

Generation Of Forests On Terrain With Dynamic Lighting And Shadowing, Jonathan Ben-David

Master's Projects

The purpose of this research project is to exhibit an efficient method of creating dynamic lighting and shadowing for the generation of forests on terrain. In this research project, I use textures which contain images of trees from a bird’s eye view in order to create a high scale forest. Furthermore, by manipulating the transparency and color of the textures according to the algorithmic calculations of light and shadow on terrain, I provide the functionality of dynamic lighting and shadowing. Finally, by analyzing the OpenGL pipeline, I design my code in order to allow efficient rendering of the forest.

Url Recommender Using Parallel Processing, Ravi Kishore Penta

Master's Projects

The main purpose of this project is to section similar news and articles from a vast variety of news articles. Let’s say, you want to read about latest news related to particular topic like sports. Usually, user goes to a particular website and goes through some news but he won’t be able to cover all the news coverage in a single website. So, he would be going through some other news website to checking it out and this continues. Also, some news websites might be containing some old news and the user might be going through that. To solve this, …

A Genetic Algorithm Scheduling Approach For Virtual Machine Resources In A Cloud Computing Environment, Shailesh Sawant

Master's Projects

In the present cloud computing environment, the scheduling approaches for VM (Virtual Machine) resources only focus on the current state of the entire system. Most often they fail to consider the system variation and historical behavioral data which causes system load imbalance. To present a better approach for solving the problem of VM resource scheduling in a cloud computing environment, this project demonstrates a genetic algorithm based VM resource scheduling strategy that focuses on system load balancing. The genetic algorithm approach computes the impact in advance, that it will have on the system after the new VM resource is deployed …

JDPET is an interactive, visual, problem solving tool that allows students to solve several different problems and learn how dynamic programming can be applied to solve these problems. JDPET also provides students with detailed feedback on the problems they attempt to solve.

Augmented-Life Phone Organizer, Chao-Hsin Shih

Master's Projects

Augmented-Life Phone Organizer (ALPO) is a geo-based mobile application for users to search for businesses and make corresponding actions such as calling, navigating, or viewing comments about the business. Users can take image notes and attach them to a virtual wall, so others can view the image at the same GPS coordinates later. Users can also view all business images and augmented notes superimposed on the real world through a mobile device screen and camera. We have measured application usability and feature practicality by conducting function tests on three users, and the results are encouraging.

Ec2lab: Saas Using Amazon Elastic Cloud Compute, Manisha Gaikwad

Master's Projects

The cloud computing is gaining popularity as it provides an infinite pool of hardware and software resources on demand. The Infrastructure-as-a-Service (IaaS) layer provides the physical resources, and relieves the users from the tedious as well as time consuming task of procuring and setting the server as well as the storage. This project harnesses the capability of the Amazon IaaS layer. The Software-as-a-Service (SaaS) application which is built on top of Amazon IaaS layer, helps the users to easily handle and connect with Amazon's Elastic Cloud Compute (EC2) instances.

X10 Vs Java: Concurrency Constructs And Performance, Anh Trinh

Master's Projects

To avoid overheating the chip, chip designers have switched to multi-cores. While multicore CPUs reserve instruction-level parallelism features that help existing applications run as if they were running under single core, applications do not reach speeds two or four times faster. Instead of relying on compiler and hardware to figure out parallelism in source code, software developers now must control parallelism explicitly in their programs. Many programming languages and libraries, such as Java, C# .NET, and OpenMP, are trying to help programmers by providing rich concurrency API. X10 is the new experimental language from IBM Research, which has been under …

Efficient Attacks On Homophonic Substitution Ciphers, Amrapali Dhavare

Master's Projects

Substitution ciphers are one of the earliest types of ciphers. Examples of classic substitution ciphers include the well-known simple substitution and the less well-known homophonic substitution. Although simple substitution ciphers are indeed simple - both in terms of their use and attacks; the homophonic substitution ciphers are far more challenging to break. Even with modern computing technology, homophonic substitution ciphers remain a significant challenge. This project focuses on designing, implementing, and testing an efficient attack on homophonic substitution ciphers. We use an iterative approach that generalizes the fastest known attack on simple substitution ciphers and also employs a heuristic search …

A Machine Learning And Compiler-Based Approach To Automatically Parallelize Serial Programs Using Openmp, Nam Quang Lam

Master's Projects

Single core designs and architectures have reached their limits due to heat and power walls. In order to continue to increase hardware performance, hardware industries have moved forward to multi-core designs and implementations which introduces a new paradigm in parallel computing. As a result, software programmers must be able to explicitly write or produce parallel programs to fully exploit the potential computing power of parallel processing in the underlying multi-core architectures. Since the hardware solution directly exposes parallelism to software designers, different approaches have been investigated to help the programmers to implement software parallelism at different levels. One of the …

N-Grams Assisted Long Web Search Query Optimization, Jehann Kersi Irani

Master's Projects

Commercial search engines do not return optimal search results when the query is a long or multi-topic one [1]. Long queries are used extensively. While the creator of the long query would most likely use natural language to describe the query, it contains extra information. This information dilutes the results of a web search, and hence decreases the performance as well as quality of the results returned. Kumaran et al. [22] showed that shorter queries extracted from longer user generated queries are more effective for ad-hoc retrieval. Hence reducing these queries by removing extra terms, the quality of the search …

Enhancing Productivity Of Recruitment Process Using Data Mining & Text Mining Tools, Charul Saxena

Master's Projects

Digital communication has significantly reduced the time it takes to send a résumé, but the recruiter’s work has become more complicated because with this technological advancement they get more résumés for each job opening. It becomes almost impossible to physically scan each résumé that meets their organization’s job requirement. The filtering and search techniques provide hundreds of résumés that can fulfill the desired criteria. Most approaches focus on either parsing the résumé to get information or propose some filtering methods. Moreover, résumés vary in format and style, making it difficult to maintain a structural repository which would contain all the …

Clustering Of Twitter Technology Tweets And The Impact Of Stopwords On Clusters, Surya Bhagvat

Master's Projects

Year of 2010 could be termed as the year in which Twitter became completely mainstream. Twitter, which started as a means of communicating with friends, became much more than its beginning. Now Twitter is used by companies to promote their new products, used by movie industry to promote movies. A lot of advertising and branding is now tied to Twitter and most importantly any breaking news that happens, the first place one goes and tries to find is to search it on Twitter. Be it the Mumbai attacks that happened in 2008, or the minor earthquakes that happened in Bay …

Layer-By-Layer Fabrication Of Covalently Crosslinked And Reactive Polymer Multilayers Using Azlactone-Functionalized Copolymers: A Platform For The Design Of Functional Biointerfaces, Maren E. Buck, David M. Lynn

Chemistry: Faculty Publications

We report a method for modulating the physicochemical properties of surfaces that is based on the reactive layer-by-layer fabrication of covalently crosslinked thin films using azlactone-functionalized copolymers. We demonstrate that copolymers containing different molar ratios of methyl methacrylate (MMA) and 2-vinyl-4,4-dimethylazlactone (VDMA) can be alternately deposited with poly(ethyleneimine) to assemble covalently crosslinked thin films. Characterization using ellipsometry demonstrates that, in general, film growth and thickness decrease as the content of reactive, azlactone functionality in the copolymer used to assemble the film decreases. Reflective infrared spectroscopy experiments demonstrate that films fabricated from MMA:VDMA copolymers contain residual azlactone functionality and that these …

Optimism And Pessimism With Expected Utility, David Dillenberger, Andrew Postlewaite, Kareen Rozen

Cowles Foundation Discussion Papers

Savage (1954) provided a set of axioms on preferences over acts that were equivalent to the existence of an expected utility representation. We show that in addition to this representation, there is a continuum of other “expected utility” representations in which for any act, the probability distribution over states depends on the corresponding outcomes. We suggest that optimism and pessimism can be captured by the stake-dependent probabilities in these alternative representations; e.g., for a pessimist, the probability of every outcome except the worst is distorted down from the Savage probability. Extending the DM’s preferences to be defined on both subjective …

Estimates Of The Social Cost Of Carbon: Background And Results From The Rice-2011 Model, William D. Nordhaus

Cowles Foundation Discussion Papers

A new and important concept in global warming economics and policy is the social cost of carbon or SCC. This concept represents the economic cost caused by an additional ton of carbon-dioxide emissions or its equivalent. The present study describes the development of the concept as well as its analytical background. We estimate the SCC using an updated version of the RICE-2011 model. Additional concerns are uncertainty about different aspects of global warming as well as the treatment of different countries or generations. The most important results are: First, the estimated social cost of carbon for the current time (2015) …

Gmm Estimation And Uniform Subvector Inference With Possible Identification Failure, Donald W.K. Andrews, Xu Cheng

Cowles Foundation Discussion Papers

This paper determines the properties of standard generalized method of moments (GMM) estimators, tests, and confidence sets (CS’s) in moment condition models in which some parameters are unidentified or weakly identified in part of the parameter space. The asymptotic distributions of GMM estimators are established under a full range of drifting sequences of true parameters and distributions. The asymptotic sizes (in a uniform sense) of standard GMM tests and CS’s are established. The paper also establishes the correct asymptotic sizes of “robust” GMM-based Wald, t , and quasi-likelihood ratio tests and CS’s whose critical values are designed to yield robustness …

Financing Of Public Goods Through Taxation In A General Equilibrium Economy: Theory And Experimental Evidence, Juergen Huber, Martin Shubik, Shyam Sunder

Cowles Foundation Discussion Papers

We compare general equilibrium economies in which building and maintenance of a depreciating public facility is financed either by anonymous voluntary contributions or by taxing agents on their income from private production. Agents start with an endowment of private goods and money, while the government starts with an endowment of public good and money. All private goods produced are tendered for sale in exchange for money in a sell-all market mechanism. Agents’ proceeds from sale are taxed, and they individually allocate their private goods between current consumption and investment in production for the following period. The optimal levels of supply …

Meritocracy Voting: Measuring The Unmeasurable, Peter C.B. Phillips

Cowles Foundation Discussion Papers

Learned societies commonly carry out selection processes to add new fellows to an existing fellowship. Criteria vary across societies but are typically based on subjective judgments concerning the merit of individuals who are nominated for fellowships. These subjective assessments may be made by existing fellows as they vote in elections to determine the new fellows or they may be decided by a selection committee of fellows and officers of the society who determine merit after reviewing nominations and written assessments. Human judgment inevitably plays a central role in these determinations and, notwithstanding its limitations, is usually regarded as being a …
