Computer Science and Engineering Senior Theses

The NameExpert is an iOS mobile application that will help users remember the names of new acquaintances. Many people often experience situations where they would run into someone they have been introduced to before, but could not remember the name to. Situations like this tend to instigate feelings of frustration and awkwardness between both parties. Names are important as part of identity and so the NameExpert would allow individuals to connect names to things like location of the meet, appearances, and other systematic ways. The NameExpert would utilize an algorithm that is derived from a proven psychological research regarding the …

Tail: Data Structures Tutorial Site, Lauren Jauco, Ian Parker, Allie Rodriguez, Tyler Upadhyaya

Computer Science and Engineering Senior Theses

Any intermediate computer programmer will learn data structures. A data structure stores and organizes in-formation into useful groups in order for a computer program to run as efficiently as possible. Data structures become extremely important when managing large amounts of data, whether it be as simple as managing statistics for a basketball team, or as critical as accounts for online banking. The current way to learn data structures is through classes and online Java applets. In classes, most professors teach by drawing the data structure and editing the information on a board. Data structure tutorial websites mimic this visual way …

Distributed Smart Camera Network For Safety And Security, Nathan Fox, Matthew Kelley, Christopher Rapa, Christopher Yarp

Interdisciplinary Design Senior Theses

Current CCTV surveillance solutions are generally retrospective tools. Because real time use of CCTV requires human monitors to view a potentially exorbitant number of video feeds, CCTV is usually only useful after an incident has occurred. However, new technologies are making it possible for machines to perform some tasks that previously required a human monitor. The proposed project seeks to augment existing CCTV systems with behavioral analytics. The system uses a series of cameras, FPGAs, and computers to track object movement throughout a facility. This information is used to build a model of normal movement. Object movements are compared against …

In our researched, we attemepted to reconfigure the android operating system so that it would be more tailored to the homeless. We first researched what features the homeless value in a mobile device. We then determined how we could improve the battery life at a user configuration level based on …

Ranked Similarity Search Of Scientific Datasets: An Information Retrieval Approach, Veronika Margaret Megler

Dissertations and Theses

In the past decade, the amount of scientific data collected and generated by scientists has grown dramatically. This growth has intensified an existing problem: in large archives consisting of datasets stored in many files, formats and locations, how can scientists find data relevant to their research interests? We approach this problem in a new way: by adapting Information Retrieval techniques, developed for searching text documents, into the world of (primarily numeric) scientific data. We propose an approach that uses a blend of automated and curated methods to extract metadata from large repositories of scientific data. We then perform searches over …

Possible Geometric Explanations For Basic Empirical Dependencies Of Systems Engineering, Francisco Zapata, Vladik Kreinovich

Departmental Technical Reports (CS)

In this paper, we provide possible geometric explanation for basic empirical dependencies of system engineering: that a properly designed system should have no more than 7 plus minus 2 elements reporting to it, and that the relative cost of correcting a defect on different stages of the system's life cycle is 3--6 on the second (design) stage, 20--100 on the third (development) stage, and 250--1000 on the fourth (production and testing) stage.

Towards Fast And Reliable Localization Of An Underwater Object: An Interval Approach, Quentin Brefort, Luc Jaulin, Martine Ceberio, Vladik Kreinovich

Departmental Technical Reports (CS)

To localize an underwater object, we measure the distance to this object from several sonar sensors with known locations. The problem is that the signal sent by some of the sonars is reflected not by the desired object(s), but by some auxiliary object and thus, the values measured by these sensors are drastically different from the distance to the desired object. To solve this problem, currently probabilistic methods are used; however, since we do not know the exact probability distributions, these methods may miss the actual location of the object. There exist interval-based methods which provide guaranteed (reliable) bounds on …

How To Explain The Definition Of Stochastic Affiliation To Economics Students, Tonghui Wang, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

To formally describe the intuitive idea of "positive correlation" between two quantities, it is often helpful to use the notion of stochastic affiliation. While this notion is useful, its usual definition is not intuitively clear -- which make it difficult to explain this notion to, e.g., economics students. To help students understand this notion, in this paper, we show how the notion of stochastic affiliation can be explained in clear probabilistic terms.

Observable Causality Implies Lorentz Group: Alexandrov-Zeeman-Type Theorem For Space-Time Regions, Olga Kosheleva, Vladik Kreinovich

Departmental Technical Reports (CS)

The famous Alexandrov-Zeeman theorem proves that causality implies Lorentz group. The physical meaning of this result is that once we observe which event can causally affect which other events, then, using only this information, we can reconstruct the linear structure of the Minkowski space-time. The original Alexandrov-Zeeman theorem is based on the causality relation between events represented by points in space-time. Knowing such a point means that we know the exact moment of time and the exact location of the corresponding event - and that this event actually occurred at a single moment of time and at a single spatial …

Regen: Optimizing Genetic Selection Algorithms For Heterogeneous Computing, Scott Kenneth Swinkleb Winkleblack

Master's Theses

GenSel is a genetic selection analysis tool used to determine which genetic markers are informational for a given trait. Performing genetic selection related analyses is a time consuming and computationally expensive task. Due to an expected increase in the number of genotyped individuals, analysis times will increase dramatically. Therefore, optimization efforts must be made to keep analysis times reasonable.

This thesis focuses on optimizing one of GenSel’s underlying algorithms for heterogeneous computing. The resulting algorithm exposes task-level parallelism and data-level parallelism present but inaccessible in the original algorithm. The heterogeneous computing solution, ReGen, outperforms the optimized CPU implementation achieving a …
