RESEARCH COMPONENT OF PHD QUALIFIER EXAM By: Saikath Bhattacharya
- Location: > See description for location
- Cost: Free
- Contact: ECE: Electrical & Computer Engineering Department
- Description: TOPIC: ANALYSIS OF FAULT TOLERANT CLASSIFIERS
LOCATION: Lester W. Cory Conference Room, Science & Engineering Building (Group II), Room 213A
ABSTRACT:
Prognostics and Health Management (PHM) has emerged as a promising approach to predict the deterioration of critical components prior to failure so that they can be maintained on an as-needed basis. PHM provides human maintenance personnel with advanced warning of potential failures and the possible fault locations. This information prepares maintenance personnel to inspect a system upon return from a mission, thereby accelerating fault isolation and diagnosis, reducing system down time.
Much of the existing research has focused on improving the accuracy of individual PHM methods. However, few studies have considered the potential benefit of utilizing multiple diverse classification techniques in a fault-tolerant architecture to increase the probability of fault detection. Moreover, these previous studies do not examine the negative impact of correlated failures, where failure in a majority of the individual PHM units can lead to system failure and possibly safety violations.
This project studied the application of fault tolerance to machine learning with an eye toward enhancing PHM and fault classification. Specifically, we apply ensemble classifiers in a majority voting scheme to failure data from the reliability research literature. Results indicate that redundancy can mask single misclassifications but correlated misclassification in two or more algorithms would lead to overall misclassification.
To mitigate the risk of correlated misclassification, we apply diversity measures, which quantify the difference between the outputs of these classification algorithms. These measures can identify better combinations of techniques from which to build an ensemble classifier, thus increasing the overall diversity and lowering the frequency of correlated failures. Six pair wise and non-pair wise diversity measures are studied in the context of an ensemble classifier for prognostics.

MASTER OF SCIENCE PROJECT DEFENSE BY: Sharath Kumar Goud Madgula
- Location: Science & Engineering Building, Lester W. Cory Conference Room: Room 213A
- Cost: Free
- Contact: ECE: Electrical & Computer Engineering Department
- Description: TOPIC: IMPLEMENTING IMAGE STITCHING USING SCALE INVARIANT FEATURE TRANSFORM
LOCATION: Lester W. Cory Conference Room, Science & Engineering Building (Group II), Room 213A
ABSTRACT:
Image Stitching is an important technique in the field of image processing and computer graphics. Stitched images are used in applications such as interactive panoramic viewing of images, architectural walk-through, multi-node movies and other applications related to modelling the 3D environment. Image processing techniques treat the images as a two-dimensional signal and thus standard signal processing techniques can be applied for them. The output of image processing process may be either an image or a set of characteristics or parameters related to the image. As one of image processing techniques, image stitching specifically presents different stages to render two or more overlapping images into a seamless stitched image, from the detection of features to blending in a final image.
In this project, a Scale Invariant Feature Transform (SIFT) algorithm is applied to perform the detection and matching control points step, due to its good properties. SIFT algorithm is a novel technique to calculate the key features of an image which are invariant in size as well as orientation. This project mainly uses SIFT algorithm for the implementation of the image stitching technique. The image stitching technique was tested on several image sets to demonstrate its effectiveness.

Wendy Wahl: ConTexts / Exhibition
- Location: University Art Gallery
- Contact: University Art Gallery
- Description: Wendy Wahl: ConTexts. Paper in 2D and 3D
Reception: AHA! Night, Dec 10, 6-8 pm, Artist Talk 7 PM
The exhibition ConTexts at the University Art Gallery in New Bedford presents a series of work by Wendy Wahl created from re-purposed encyclopedias. Her 2D works, made of hundreds of rolled paper strips glued onto a wooden panel, are sculpted into complex, repetitive reliefs. When light hits, they create an amazing universe that changes in surprising ways as the visitor walks by, often revealing an underlying geometry. In Wahl's newest work created for the exhibition, she uses the tops of the pages with golden edges taken from old Funk and Wagnalls Encyclopedias. Ms. Wahl's 3D pieces, enhanced by shadow-producing light and made from cut pages released from its binding, might remind visitors of underwater creatures with tentacles reaching out from the walls or into the gallery space. ConTexts brings new and inspiring meaning to the phrase 'reading a page'.
For the last ten years Wendy Wahl's studio work has included a series that is created from thousands of pages of discarded and some now out of print volumes that include the Encyclopaedia Britannica, World Book, Collier's, Funk and Wagnalls and a variety of Dictionaries. The outcome of this work is an expression of her view of the connections between nature and culture. Wahl's interest is considering the associations between the tree of life, defined as the patterns of relationships that link all earthâ's species and the tree of knowledge, defined as the connected branches of human thought realized in the form of writing and speaking. This work is part of an ongoing experiment that uses the potency of printed text on paper. She is using a cultural artifact as her material for many reasons that include its unique physical qualities, the meanings that it carries and to recognize its existence. By restructuring familiar elements that in a particular format belongs to a collective consciousness, Wahl is commenting on an aspect of our station in time.
Wendy Wahl's work has been exhibited internationally and is in a number of private and public collections including the Cooper-Hewitt Museum, NY and the RISD Museum. In 2010, she was selected for Networks, a project documenting Rhode Island artists through video and exhibition. The same year, she was commissioned to create a piece for the entrance of SOFA (Sculpture, Objects and Functional Art exposition) at the Park Avenue Armory, NY. Her work has been the subject of exhibitions at the Grand Rapids Art Museum, Michigan, the Newport Art Museum, RI and Fuller Craft Museum in Brockton, MA. She has received artist fellowship awards from the Rhode Island State Council on the Arts and the US Ambassador to Tashkent, Uzbekistan selected her work for his residence through the Art in Embassy Program. She has been recognized in numerous publications including Art News, Boston Globe, Casa Vogue, Providence Journal, Metropolis, The New York Times, Architectural Digest, The New Yorker, the Britannica blog, the Curated Object and The Wall Street Journal. Currently she is a lecturer at The New School - Parson's, Department of Constructed Environments. She received an MAE in Textile Art from the Rhode Island School of Design and a BA in Art from California State University at Northridge. She resides in Rhode Island with her husband, John Dunnigan, and their daughter, Hannah. Wendy Wahl was born in Los Angeles, California in 1961

The exhibition is curated by Viera Levitt, Gallery Director and is open through Feb 14, 2016.
