ECE Seminar* Research Presentations
- Location: DION Building
, 285 Old Westport Road, Dartmouth, MA
- Cost: free
- Contact: ECE: Electrical & Computer Engineering Department
- Description: Location: DION Building - Room 114
First Presenter: Mr. Amir Ehsani Zonouz, Ph.D. Student, UMass Dartmouth
Topic: Reliability Based Optimization in Hybrid Wireless Sensor Networks
Abstract:
Sensor nodes in wireless sensor networks (WSNs) are usually battery-powered sensor nodes (BPSNs) and can rarely meet design goals such as network lifetime, energy and reliability. Energy-harvesting sensor nodes (EHSNs) are an alternative type of sensor nodes, which are capable of converting different types of energy to electrical energy. They have longer lifetime but higher cost than BPSNs. Combining BPSNs and EHSNs in a heterogeneous WSN has the potential to deal with the conflicting design goals. In addition, consider certain scenarios where replacing batteries of BPSNs is impossible, EHSNs can be deployed instead to satisfy the quality of service (QoS) of applications running on the hybrid WSN. In this work, we study a hybrid WSN including both types of sensor nodes to deal with the network reliability and cost requirements, particularly, the limited lifetime of BPSNs and high cost of EHSNs. The problem is to find the optimal locations for a specific number of EHSNs in the hybrid WSN with the objective to provide the best combination of average path reliability, implementation path cost, and average energy consumption based on the QoS requirements. Both the centrality concept and the multivariable nonlinear programming method are explored to find the optimal positions for EHSNs in the hybrid WSN.
Biography:
Mr. Amir Ehsani Zonouz is currently pursuing the PhD degree in computer engineering at University of Massachusetts, Dartmouth, USA. From 2011, he is a Research Assistant in Dependable Computing and Networking (DCN) research group. His research centers on reliability and energy efficiency of wireless networks. From 2007 to 2010, he also worked on Computer Architecture, System/Network-On-Chip and FPGA Design.

Blended Learning: Finding the Mix
- Location: Online
- Contact: CITS Instructional Development
- Description: This online workshop focuses on blended learning strategies and developing faculty abilities to successfully integrate online components of a course with face-to-face components Faculty are invited to engage in a 10 day asynchronous workshop designed to introduce blended learning techniques and facilitate faculty planning of a blended course. The workshop includes a focus on assessment to help faculty not only assess student learning outcomes, but also to assess how well the “blend” works to facilitate student learning.

Joint Mechanical Engineering (MNE) and Engineering Applied Science (EAS) Seminar
- Location: Textiles Building 101E
- Contact: Mechanical Engineering Department
- Description: We are pleased to announce the following SEMINAR:
Joint Mechanical Engineering (MNE) and Engineering Applied Science (EAS) Seminar
Friday, April 10th 2015
2:00 p.m. 3:00 p.m.
Textile Building, Room 101E
SPEAKER:
Dr. Allan Pierce, Adjunct Professor at UMD Mechanical Engineering and Professor Emeritus of ME at Boston University
TOPIC:
Slow Deaths of Vibrations and Waves
ABSTRACT:
Vibrations are the most fundamental of dynamical process, and they affect a vast range of technologies and science. While there is considerable understanding concerning the nature of vibrations and waves (which are vibrations that move), there is not much of a fundamental understanding of the processes (typically small-scale phenomena, nano-scale and smaller) that cause such vibrations to die out. The speaker and others have been involved in several NSF-sponsored workshops to discuss possible future interdisciplinary research efforts that will concentrate on the science and technology of vibrational energy transport and dissipation at small scales. The grand challenge is whether we can advance the technologies associated with vibrations so that a fundamental understanding of small-scale phenomena associated with vibrations can be fully utilized. Present talk will review the past heuristic techniques for dealing with the damping of vibrations, then review what is currently known in terms of fundamentals, including those intrinsically quantum mechanical, and will then suggest the nature of future interdisciplinary research that can meet this challenge.
BIO:
Allan D. Pierce is Professor Emeritus of Mechanical Engineering at Boston University, having retired from teaching in 2012. His long academic career began in 1966 with Assistant- and Associate-Professor positions at MIT, and continued with appointments as a Regents Professor at Georgia Tech, as the Holder of the Leonhard Chair in Engineering at Penn State, and as Chair of the Department of Aerospace and Mechanical Engineering at Boston University. Between 1999 and 2014, he was the Editor-in-Chief of the Acoustical Society of America (ASA). Honors received over the years include the Silver Medal in Physical Acoustics and the Gold Medal from the ASA, the Per Bruel Gold Medal in Noise Control and Acoustics from the ASME, the Gold Medal of the Acoustical Foundation of India, and the Rossing Prize for Education in Acoustics from the ASA. His textbook "Acoustics: an Introduction to its Fundamental Principles and Applications" has been in print since 1981 and is a leading reference work in acoustics.
