    Some belated news from me: since 2010 I've been leading a NSF funded multicampus project on Named Data Networking (NDN), the design of a new Internet architecture.
    Here is the project website:
    The heart of today's Internet architecture is a simple, universal network layer (IP) which implemented all the functionality necessary for global interconnectivity. This "thin waist" was the key enabler of the Internet’s explosive growth, but one of its design choices is also the root cause of today’s Internet problems: The Internet was designed as a point-to-point communication network, so the only entities that could be named in its packets are communication endpoints (IP addresses). Recent growth in e-commerce, digital media, social networking, and smartphone applications has resulted in the Internet primarily being used as a distribution network. Solving distribution problems with a point-to-point communication architecture is complex and error prone. NDN retains the Internet’s hourglass architecture but evolves the thin waist to allow the creation of completely general distribution networks. The core element of this evolution is removing the restriction that packets can only name communication endpoints. As far as the network is concerned, the name in an NDN packet can be anything — an endpoint, a chunk of movie or book, a command to turn on some lights, etc. This conceptually simple change allows NDN networks to use almost all of the Internet’s well understood and well tested engineering properties to efficiently solve not only communication problems but also digital distribution and control problems.

    Last week we held the 2nd NDN Community meeting at UCLA,
    which was attended by over 100 people from 50-60 organizations around the world, showing the rapid growth of the NDN research and development community.

    New Ductile Fracture Models
    Resilient infrastructure is the ability of structural systems to withstand extreme natural or man-made hazards without complete collapse. It is therefore essential to develop accurate predictive models that can be used to quantify ductility in structural elements and components all the way up to and including failure. Current ductile fracture models are known to provide accurate results only under specific range of stress states. A new ductile fracture model under monotonic and cyclic loading has been developed by Dr. Mahmoud and his student, Huajie Wen, and have been verified against a large set of experimental data under a wide range of stress states. The developed model has shown to yield very accurate prediction, which will provide a substantial opportunity for a new set of failures in components or systems to be assessed. Two recent papers, Part I and Part II on the developed model have been published in the ASCE Journal of Engineering Mechanics. The models have been successfully used to simulate system collapse in structures (please see the attached photo).

    MIT Press book on engineering work and technology
    This year, I published a MIT Press book with Paul Leonardi titled, Technology Choices: Why Occupations Differ in Their Embrace of New Technology. Drawn from a decade's worth of intense fieldwork in three engineering occupations (automotive engineering, hardware engineering, and structural engineering), the book shows how occupational factors such as product liability, government regulation, product complexity, and the rate of knowledge change in a profession shape engineers' choices of when and how to employ advanced new computational, graphical, and logical technologies for design and analysis. We consider three choices in particular: what tasks to allocate to computers, whether or not to automate any part of design and analysis, and whether or not to use technology to aid remote work arrangements such as offshoring. Detailed descriptions of engineers at work illustrate and provide support for our argument that occupational factors (and not the technology itself or the organizations in which engineers work) strongly shape technology choices.

    Associate Professor at North Carolina State University, Raleigh, North Carolina said:
    1 month, 3 weeks and 1 day ago
    We have developed a novel control algorithm that can automatically tune the prosthesis control to provide personalized assistance to individuals with lower limb amputations. The research has been published on Annals of Biomedical Engineering. The research news has been features on NSF front page recently.

    Below is the full story reported at

    When amputees receive powered prosthetic legs, the power of the prosthetic limbs needs to be tuned by a prosthetics expert so that a patient can move normally – but the prosthetic often needs repeated re-tuning. Biomedical engineering researchers at North Carolina State University and the University of North Carolina at Chapel Hill have now developed software that allows powered prosthetics to tune themselves automatically, making the devices more functionally useful and lowering the costs associated with powered prosthetic use.

    “When a patient gets a powered prosthetic, it needs to be customized to account for each individual patient’s physical condition, because people are different in size and strength. And that tuning is done by a prosthetist,” says Helen Huang, lead author of a paper on the work and an associate professor in the biomedical engineering program at NC State and UNC-Chapel Hill. “In addition, people are dynamic – a patient’s physical condition may change as he or she becomes accustomed to a prosthetic leg, for example, or they may gain weight. These changes mean the prosthetic needs to be re-tuned, and working with a prosthetist takes time and money.”

    To address this problem, the researchers developed an algorithm that can be incorporated into the software of any powered prosthesis to automatically tune the amount of power a prosthetic limb needs in order for a patient to walk comfortably. The algorithm would not only make it easier for patients to walk while reducing prosthetist-related costs, but would also allow a prosthesis to adjust to changing conditions. Video of the technology in action can be seen here.

    “For example, the algorithm could provide more power to a prosthesis when a patient carries a heavy suitcase through an airport,” Huang says.

    The system works by taking into account the angle of the prosthetic knee while walking.

    Powered prosthetic legs are programmed so that the angle of the prosthetic joints – the knee or ankle – while walking mimics the normal movement of the joints when an able-bodied person is walking. During the conventional prosthetic tuning process, a prosthetist adjusts the powered prosthesis’s system so that it exerts the power necessary to recreate those normal joint motions while walking.

    But changes in a person’s weight, or gait, can affect the prosthesis’s ability to achieve that “natural” joint angle.

    The automatic-tuning algorithm takes a similar approach, tracking the angle of the prosthetic joint while walking. But it is able to adjust the amount of power the prosthesis receives in real time, in order to maintain the proper angle.

    “In testing, we found that the computer – using the algorithm – performed better than prosthetists at achieving the proper joint angle,” Huang says. “So we know our approach works. But we’re still working to make it better.

    “Prosthetists rely on years of experience to not only adjust the joint angle, but to adjust a prosthesis to help patients maintain a comfortable posture while walking,” Huang adds. “We’re not yet able to replicate the prosthetist’s success in achieving those comfortable ‘trunk motions,’ but it’s something we’re working on.”

    The paper, “A Cyber Expert System for Auto-Tuning Powered Prosthesis Impedance Control Parameters,” is published in the journal Annals of Biomedical Engineering. The paper was co-authored by Dustin Crouch, Ming Liu, Gregory Sawicki and Ding Wang, of the joint biomedical engineering program at NC State and UNC-Chapel Hill. The work was supported by the National Science Foundation under grants 1361549, 1406750, and 1527202.

    “A Cyber Expert System for Auto-Tuning Powered Prosthesis Impedance Control Parameters”

    Authors: He Huang, Dustin L. Crouch, Ming Liu, Gregory S. Sawicki and Ding Wang, North Carolina State University and the University of North Carolina at Chapel Hill.

    Published: Sept. 25, Annals of Biomedical Engineering

    DOI: 10.1007/s10439-015-1464-7

    Abstract: Typically impedance control parameters (e.g. stiffness and damping) in powered lower limb prostheses are fine-tuned by human experts, which is time and resource intensive. Automated tuning procedures would make powered prostheses more practical for clinical use. In this study, we developed a novel cyber expert system (CES) that encoded human expert (HME) tuning decisions as computer rules to auto-tune control parameters for a powered knee (passive ankle) prosthesis. The tuning performance of CES was preliminarily quantified on two able-bodied subjects and two transfemoral amputees. After CES and HME tuning, we observed normative prosthetic knee kinematics and improved or slightly improved gait symmetry and step width within each subject. Compared to HME, the CES tuning procedure required less time and no human intervention. Hence, using CES for auto-tuning prosthesis control was a sound concept, promising to enhance the practical value of powered prosthetic legs. However, the tuning goals of CES might not fully capture those of the human expert. This was because we observed that HME tuning reduced trunk sway, while CES sometimes led to slightly increased trunk motion. Additional research is still needed to identify more appropriate tuning objectives for powered prosthetic legs to improve amputees’ walking function.

    Full, Fellow, Fulbright!
    The 2014-2015 academic year was an exciting one for me! I was promoted to full professor at the University of Wisconsin at Madison, elected a Fellow of the American Society of Medical and Biological Engineering (AIMBE), and named a Fulbright Scholar. For the 2015-16 academic year, my family (husband and 3 daughters) and I will be living in Israel. In addition to doing research at Tel Aviv University, I hope to visit other institutions to meet colleagues and discuss cutting-edge approaches to biomedical engineering research and education. My family and I also plan to travel extensively and look forward to learning about the rich and complex history of the region.
