MASTER OF SCIENCE THESIS DEFENSE BY: Sri Shanmukha Naraharisetti
- Location: Science & Engineering Building, Lester W. Cory Conference Room: Room 213A
- Cost: Free
- Contact: ECE: Electrical & Computer Engineering Department
- Description: TOPIC: SQUARE ROOT CARRY SELECT ADDER USING BEC FOR AREA EFFICIENT PROCESSORS
LOCATION: Lester W. Cory Conference Room, Science & Engineering Building (Group II), Room 213A
ABSTRACT:
Arithmetic functions are the basic operations in many data processors. In most of the digital adders the speed of addition is limited by time taken for the carry to propagate through the adder. Square Root Carry Select Adder (SQRT CSLA) is one of the adders which is used to perform the addition operations very fast [1], but due to the ripple carry adders (RCA) used in the SQRT CSLA module the number of AOI gates used here are more compared to the AOI gates used in the modified SQRT CSLA which leads them to occupy more area. Modified SQRT CSLA limits the number of gates (area) by using Binary to Excess 1 Converters (BEC) in place of RCAs.
The Area, power and Delay parameters of the modified SQRT CSLA using BEC are determined from simulations with Synopsys tools and compared with SQRT CSLA which uses RCA. Based on the comparison of results of the ordinary module and modified module, the better Design of the two models is brought out.

DOCTOR OF PHILOSOPHY DISSERTATION DEFENSE BY: Saurav R. Tuladhar
- Location: > See description for location
- Cost: Free
- Contact: ECE: Electrical & Computer Engineering Department
- Description: TOPIC: IMPROVED SAMPLE MATRIX INVERSION ADAPTIVE BEAMFORMERS FOR UNIFORM LINEAR ARRAYS USING ARRAY POLYNOMIALS
LOCATION: Dion Building, Room 109
ABSTRACT:
Adaptive beamformers (ABFs) place deep beampattern notches near interferers to suppress the interferers' power in the ABF output. The sample matrix inversion (SMI) Minimum Variance Distortionless Response (MVDR) ABF computes the beamformer weights by substituting the sample covariance matrix (SCM) for the unknown ensemble covariance matrix in the MVDR expression. Errors in the SCM estimate of interferer direction due to limited sample support or interferer motion distorts the ABF beampattern and degrades the ability of the ABF to suppress the interferer. For beamformers using uniform linear arrays (ULA), the beampattern can be represented as a polynomial. The array polynomial is the z-transform of the beamformer weights. Evaluating the array polynomial on the unit circle in the complex plane yields the beampattern. For the ensemble MVDR beamforming using a ULA, the array polynomial zeros are constrained to fall on the unit circle. But the SMI MVDR polynomial zeros generally do not fall on the unit circle. The first part of the dissertation develops a model for the ensemble MVDR polynomial zero locations assuming a single interferer present in white background noise. The model illuminates the trade off balancing the interferer suppression and the white noise gain by the ensemble MVDR. Secondly, the dissertation proposes the unit circle MVDR (UC MVDR) beamformer which projects the SMI MVDR polynomial zeros radially on to the unit circle to satisfy the constraint on the zeros of ensemble MVDR polynomial. Numerical simulations show that the UC MVDR beamformer suppresses interferers better than the SMI MVDR and diagonal loaded MVDR beamformer and also improves the white noise gain (WNG). Finally, the dissertation proposes the double zero (DZ) MVDR ABF as a new approach to notch broadening. The array polynomial for the DZ MVDR ABF has second-order zeros, producing broader and deeper notches in the interferer direction. The DZ MVDR ABF outperforms the SMI MVDR and covariance matrix tapered ABFs in simulations with stationary and moving interferers.

MASTER OF SCIENCE THESIS DEFENSE BY: Vidhyashree Nagaraju
- Location: Science & Engineering Building, Lester W. Cory Conference Room: Room 213A
- Cost: Free
- Contact: ECE: Electrical & Computer Engineering Department
- Description: TOPIC: ALGORITHMS FOR NONHOMOGENEOUS POISSON PROCESS (NHPP)
SOFTWARE RELIABILITY MODELS AND SOFTWARE REJUVENATION
CONSIDERING CORRELATED FAILURES
LOCATION: Lester W. Cory Conference Room, Science & Engineering Building (Group II), Room 213A
ABSTRACT:
Nonhomogeneous Poisson process software reliability growth models (SRGM) enable several quantitative metrics that can be used to guide important decisions during the software engineering life cycle such as testing resource allocation and release planning. However, many of these SRGM possess complex mathematical forms that make them difficult to apply in practice. Specifically, traditional statistical procedures such as maximum likelihood estimation must solve a system of non-linear equations to identify the numerical parameters that best characterize a set of failure data. Recently, researchers have made significant progress toward overcoming this difficulty by developing an expectation-maximization (EM) algorithm that exhibits better convergence properties and can therefore find the maximum likelihood estimates of complex SRGM with greater ease. However, this approach is computationally intensive and therefore slow for complex models. This thesis presents: (i) adaptive EM and (ii) Implicit expectation conditional maximization (IECM) algorithms to avoid the computationally intensive steps present in previous techniques and to identify the MLEs with respect to all model parameters.
In software reliability models, another critical metric is availability. Phenomenon such as software aging can cause failure of a critical application which may result in a significant loss of life, compromise confidential data, or produce economic loss. Software aging is addressed by a method known as software rejuvenation, which is a proactive fault management technique with the goal of postponing or preventing crash failures and/or performance degradation. Most rejuvenation methods ignores the impact of correlation on the reliability of a component based system. Therefore, this thesis presents: (iii) an extended software rejuvenation model to explicitly consider correlated failures, which enables the computation of software rejuvenation schedules to achieve high availability and low downtime cost.

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
