RESEARCH COMPONENT OF PHD QUALIFIER EXAM BY: Bentolhoda Jafary
- Location: > See description for location
- Cost: Free
- Contact: ECE: Electrical & Computer Engineering Department
- Description: TOPIC: IMPACT OF CORRELATED COMPONENT FAILURES ON MAINTENANCE POLICIES FOR FAULT-TOLERANT SYSTEMS
LOCATION: Lester W. Cory Conference Room, Science & Engineering Building (Group II), Room 213A
ABSTRACT:
The primary goal of maintenance is to minimize the risk and consequences of component and system failures. Maintenance actions can be divided into two subcategories: (i) Preventive Maintenance (PM) at predetermined time intervals prior to failure and (ii) Emergency Repair (ER) upon failure, where ER >> PM with respect to cost or downtime. Many maintenance models have been developed over the past several decades. However, most of them assume component failures are statistically independent. This assumption simplifies the calculations, but is especially dangerous for safety critical maintained systems because correlated failures can lower the mean time to failure and increase the probability of ER. We study the impact of correlated component failures in the context of five maintenance policies, including: (i) periodic group repair based on operation time, (ii) preventive maintenance: minimal repair with complete renewal model, (iii) periodic preventive maintenance: minimal repair with partial renewal, (iv) age replacement to minimize cost, and (v) age replacement to maximize availability. Examples illustrate that our approach identifies optimal maintenance strategies despite the presence of correlated failures.
NOTE: All ECE Graduate Students are ENCOURAGED to attend.
All interested parties are invited to attend. Open to the public.

ECE Seminar* Speaker: Dr. Tarik Taleb, Aalto University
- Location: Science & Engineering Building, Lester W. Cory Conference Room: Room 213A
- Cost: Free

- Description: Topic: TOWARDS 5G: CARRIER-GRADE PROGRAMMABLE VIRTUAL MOBILE NETWORKS
Location: Lester W. Cory Conference Room, Science & Engineering Building (Group II), Room 213A
Abstract:
The telecom industry keeps reinventing itself. Soon, the world will be experiencing the 5th generation mobile networks (5G), also referred to as beyond 2020 mobile communication systems. Major obstacles to overcome in 5G systems are principally the highly centralized architecture of mobile networks along with the static provisioning and configuration of network nodes built on dedicated hardware components. This has resulted in lack of elasticity and flexibility in deployment of mobile networks; rendering their run-time management costly, cumbersome and time-consuming. Software Defined Networking, Network Function Virtualization, and Cloud Computing, along with the principles of the latter in terms of service elasticity, on-demand features, and pay-per-use, could be important enablers for various mobile network enhancements, to specifically virtualize and decentralize mobile networks using general-purpose COTS (commercial of the shelf) hardware. For this purpose, different requirements have to be met and numerous associated challenges have to be subsequently tackled. This talk will touch upon the recent trends the mobile telecommunications market is experiencing and discuss the challenges these trends are representing to mobile network operators. To cope with these trends, the talk will then showcase the feasibility of on-demand creation of cloud-based elastic mobile networks, along with their lifecycle management. The talk will introduce a set of technologies and key architectural elements to realize such vision, turning end-to-end mobile networking into software engineering.
The Seminars is open to the public free of charge.

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.
