IEEE International Conference on Communications 2012

In June 2012, Hasan Tuncer will present the following two papers at the IEEE International Conference on Communications (ICC) – Next Generation Networking Symposium and FutureNet workshop, respectively:

H. Tuncer, Y. Nozaki, and N. Shenoy, “Virtual mobility domains - a mobility architecture for the future internet,” in Communications (ICC), 2012 IEEE International Conference on, june 2012, to be published.

H. Tuncer, Y. Nozaki, and N. Shenoy,  “Seamless user mobility in virtual mobility domains for the future internet,” in Communications Workshops (ICC), 2012 IEEE International Conference on, june 2012, to be published.

Hasan’s papers present novel mobility architecture called Virtual Mobility Domains that is designed to work with the Floating Cloud Tiered Internetworking model. Virtual Mobility Domains supports both inter Autonomous System (macro) and intra Autonomous System (micro) mobility by leveraging a tiered addressing, a network cloud concept, and a unique packet forwarding scheme introduced by the Floating Cloud Tiered Internetworking model. The proposed mobility architecture is distinct from others by not using IP addressing and classic routing protocols, and deploying user-centric overlapping mobility domains. The comparative simulation study of Virtual Mobility Domains against Mobile IPv6, Hierarchical Mobile IPv6, and Proxy Mobile IPv6 using OPNET shows that Virtual Mobility Domains brings lower latency, lesser signaling overhead, and fewer packets loss during handoffs, especially during inter Autonomous System roaming. The results highlight the potential for a seamless mobility management.

In the same conference, Yoshihiro Nozaki will present the following paper:

Y. Nozaki, H. Tuncer, and N. Shenoy,  “ISP Tiered Model based Architecture for Routing Scalability,” in Communications Workshops (ICC), 2012 IEEE International Conference on, june 2012, to be published.

This research project is focused on addressing and routing for a clean-slate future Internet architecture, called the Floating Cloud Tiered (FCT) internetworking model. Internet today is faced with problems due to the growing routing table sizes and high churn rates that occur subsequent to changes in routing information. With initiatives for new Internet designs underway, the problem can be addressed through new internetworking models that consider these factors. In this article one such model that is based on the tiered structure of ISPs (used to define their business relationships) is investigated. The model does not use IP and its routing protocols. An analysis of the model applied to the worldwide network of Autonomous Systems (AS) and ISPs shows the significant reduction in routing table sizes and churn rates that can be achieved with the proposed model even under an un-optimized case.

ACII 2011

Yuqiong (Joan) Wang presented her paper "Using Facial Emotional Signals for Communication Between Emotionally Expressive Avatars in Virtual Worlds" at the Doctoral Consortium of the Affective Computing and Intelligent Interaction Conference (ACII 2011) in Memphis TN, October 12, 2011.  The paper was nominated for Best Paper in the Doctoral Consortium.

International Conference on Document Analysis and Recognition

In September 2011, Lei Hu presented a paper at the International Conference on Document Analysis and Recognition ( in Beijing:

L. Hu and R. Zanibbi. (2011) HMM-Based Recognition of Online Handwritten Mathematical Symbols Using Segmental K-means Initialization and a Modified Pen-up/down Feature. Proc. Int'l. Conf. Document Analysis and Recognition, pp. 457-462, Beijing.

Lei's paper presents a simple technique that performs competitively with state-of-the-art methods for recognizing handwritten mathematical symbols. Lei also presented this work at the ICDAR Doctoral Symposium organized by Dr. Daniel Lopresti (Lehigh University,, where PhD students from around the globe presented their research-in-progress to leaders in the area and one another.

Software Lunch (2011 Winter)

Software lunch hosts paper discussions and occasional talks relevant to building reliable, secure, and productive software. Topics will focus on software engineering, but will also touch the areas of programming languages, systems and software security. The theme for Winter 2011 is program analysis and its applications to program understanding, software testing, bug detection/diagnosis and software security.
Coordinator: Wei Le (
When: 1:00 - 1:50pm Thursdays

MICCAI'2011 and CinC'2011

The GCCIS computational biomedicine research team has continued its success in MICCAI, the foremost international scientific event in the field of medical image computing and computer-assisted intervention. Following a rigorous double-blind, full-paper review process on 817 submissions, RIT researchers (PhD students, postdocs, and faculty) have shared their latest works with the rest of the world on cardiac electrophysiology, cardiac kinematics and mechanics, functional understanding of brain activities, and dynamic positron emission tomography on drug kinetics.   
Some highlights from the 14th annual meeting held last week in Toronto, attended by more than 1000 leading scientists, engineers, and clinicians in the world:

  • "Transmural Electrophysiologic and Scar Imaging on Porcine Heart with Chronic Infarction"
    • Linwei Wang (GCCIS faculty), Fady Dawoud (Johns Hopkins postdoc), Ken Wong (INRIA researcher / GCCIS visiting faculty), Heye Zhang (Chinese Academy of Sciences faculty), Huafeng Liu (GCCIS faculty), Albert Lardo (Johns Hopkins faculty), and Pengcheng Shi (GCCIS faculty)    
    • Best Paper Award in Statistical Atlases and Computational Models of the Heart: Imaging and Modeling Challenges. 
    • (Bill saw, and liked, the much earlier work almost three years ago during the Hamamatsu trip, which was Linwei's dissertation topic.)
  • "A Comparative Study of Physiological Models on Cardiac Deformation Recovery: Effects of Biomechanical Constraints"
    • Ken Wong, Linwei Wang, Huafeng Liu, and Pengcheng Shi
  • "Robust Estimation of Kinetic Parameters in Dynamic PET Imaging"
    • Fei Gao (GCCIS postdoc), Huafeng Liu, and Pengcheng Shi
  • "Detrend-Free Hemodynamic Data Assimilation of Two-Stage Kalman Estimator"
    • Zhenghui Hu (GCCIS postdoc / Zhejiang University faculty), and Pengcheng Shi
  • "Volumetric Modeling the Electromechanics of the Heart"
    • Hongda Mao (GCCIS PhD student), Linwei Wang, Ken Wong, Huafeng Liu, Pengcheng Shi
  • "Toward Clinically-Feasible Noninvasive Electrophysiological Imaging: Investigating the Impact of Local Anatomical Details"
    • Azar Rahimi (GCCIS PhD student), Hongda Mao, Pengcheng Shi, and Linwei Wang

Also last week, at the 38th annual CinC meeting, the flagship scientific conference on computing in clinical cardiology and cardiovascular physiology, Dr. Linwei Wang (GCCIS assistant professor) gave the closing plenary speech on Mapping the Transmural Scar and Activation for Patients with Ventricular Arrhythmia, which is based on the ongoing collaboration between RIT (Linwei Wang, Huafeng Liu, Pengcheng Shi), Johns Hopkins (Fady Dawoud), INRIA (Ken Wong), Chinese Academy of Sciences (Heye Zhang), and Dalhousie (John Sapp, Milan Horacek). Hongda Mao, GCCIS PhD student, also present his research on "A Coupled Heart-Torso Framework for Cardiac Electrocardiographic Simulation" at the meeting.
