Yilong Geng (EE PhD candidate) presenting at NSDI '18
July 2018

Interdisciplinary research between professor Balaji Prabhakar, his team, and Google has produced a software clock synchronization system that can track time down to 100 billionths of a second.

The paper, presented at NSDI '18, describes a nanosecond-level clock synchronization that can be an enabler of a new spectrum of timing- and delay-critical applications in data centers.

The current, popular clock synchronization algorithm, NTP, can only achieve millisecond-level accuracy. Current solutions for achieving a synchronization accuracy of 10s-100s of nanoseconds require specially designed hardware throughout the network for combatting random network delays and component noise or to exploit clock synchronization inherent in Ethernet standards for the PHY.

The research team presents HUYGENS, named for the Dutch physicist Christiaan Huygens, who invented the pendulum clock in 1656. HUYGENS is a software clock synchronization system that uses a synchronization network and leverages three key ideas. First, coded probes identify and reject impure probe data—data captured by probes which suffer queuing delays, random jitter, and NIC timestamp noise. HUYGENS then processes the purified data with Support Vector Machines, a widely-used and powerful classifier, to accurately estimate one-way propagation times and achieve clock synchronization to within 100 nanoseconds. Finally, HUYGENS exploits a natural network effect—the idea that a group of pair-wise synchronized clocks must be transitively synchronized— to detect and correct synchronization errors even further.

The importance of technical advances in measuring time was underscored by European regulations that went into effect in January and that require financial institutions to synchronize time-stamped trades with microsecond accuracy.

Being able to trade at the nanosecond level is vital to Nasdaq. Two years ago, it debuted the Nasdaq Financial Framework, a software system that it has envisioned eventually trading everything from stocks and bonds to fish and car-sharing rides.

The new synchronization system will make it possible for Nasdaq to offer "pop-up" electronic markets on short notice anywhere in the world, Mr. Prabhakar said. He cited the World Cup as a hypothetical example of a short-term electronic marketplace.

"There are tickets needed, housing, people will need transportation," he said. "Think of an electronic market almost like a massive flea market hosted by Nasdaq software."

The HUYGENS team is Yilong Geng (EE PhD candidate), Shiyu Liu (EE PhD candidate), and Zi Yin (EE PhD candidate), Ashish Naik (Google Inc.) EE professors Balaji Prabhakar and Mendel Rosenblum, and Amin Vahdat (Google Inc.)

The 2018 University Rover Challenge (URC) took place in at the Mars Desert Research Station (MDRS) in Utah, May 31 - June 2. Thirty-six teams from 10 countries participated in the annual event. Both graduate and undergraduate students make up the teams.

This is the first year that the Stanford Robotics Club has participated in the competition. The Stanford MARS Rover Team placed 34th, and is already making plans for the 2019 competition.

The URC required completion of the same tasks as in previous years: Sample Cache Task, Extreme Retrieval and Delivery Task, Equipment Servicing Task, and the Autonomous Traversal Task. Teams and their rovers were additionally challenged with harder versions of several tasks. The most exciting task of 2018 proved to be the Equipment Servicing Task, which featured a custom lander designed and built by a URC sponsor. Rovers were required to load a canister into the lander, and conduct a series of complex procedures required to "launch" this lander from Mars back to Earth.

The 2018 Stanford Robotics Mars Rover Team members are:

  • Shi Tuck - Sophomore in EE - Electrical systems
  • Christina (Tina) Li - Sophomore in CS - Drive Mechanical

Anthropology and EE major Jack Andraka
May 2018

Jack Andraka, a junior in anthropology and electrical engineering has been awarded the 2018 Truman Scholarship for Graduate Studies. He plans to put his training in engineering, anthropology and data science to work as a public health physician devoted to addressing global health inequities affecting citizens in low- and middle-income countries.

Jack is one of 59 exceptional college students chosen from across the nation for the scholarship, which provides up to $30,000 for graduate study – in the United States or abroad – to students who want to attend graduate school in preparation for a career in public service.

Andraka's honors thesis in anthropology focuses on Sierra Leone: Disease Dollars: An Ethnographic Study of Foreign Aid and Ebola in Sierra Leone. Andraka hopes to study how environmental contaminants violate the health and human rights of disadvantaged populations in the impoverished West African country.

He is also writing an honors thesis in electrical engineering, A Novel Paper Biosensor for the Detection of Infectious Diseases and Environmental Contaminants, which describes the sensors he developed that detect 20 different diseases or contaminants in five minutes at a cost of less than one cent.

As a Truman Scholar, Andraka intends to enter an MD/MPH (Doctor of Medicine/Master of Public Health) program specializing in global health.

"The MD degree would enable me to frame my engineering background within medicine and provide me with an appreciation for the clinical realities of working in global health," Andraka wrote in his Truman Scholarship application. "In doing so, I will be able to work with communities in clinical settings to better understand locally relevant issues and design programs to address them. The Master of Public Health degree, alongside my anthropology training, will provide me with a deep understanding of broader socioeconomic, environmental and political determinants of health."

Eventually, Andraka hopes to become a public health physician devoted to addressing the global health inequities in low- and middle-income countries, where life expectancy is 36 years lower than in high-income countries.

Please join us in congratulating Jack on his excellent achievement!

Angad Rekhi (PhD ’20), Allen Building, Stanford EE
April 2018

Come to the Allen Building and view the original wall art designed by EE PhD candidate Angad Rekhi.

Angad Rekhi has spent many hours in the Allen Building, researching & reflecting on low power circuits and systems. As a member of the Arbabian Lab, he also helped develop a low power wake up receiver for IoT.

Angad was intrigued by the call to submit a design for the Allen Building entrance. The design challenge opened in October 2017, encouraging students, faculty & staff to create a visually representative piece that illustrates the research done within the Allen Buildings.

Angad's concept illustrates the entire electrical engineering design hierarchy – from a device-focused perspective at the far left, through chip and board design in the center, to end applications on the far right. "Design at all levels occurs in the Allen Buildings. They contain spaces and labs for the full process of design and build, from concept to product," states Angad. "For example, ExFab allows rapid prototyping of microelectronics, and the SPF (System Prototyping Facility) supports electronic sub-system design. So really, anyone on campus can go from idea to product within these walls."

Angad Rekhi (PhD ’20) posing with his wall design in the Allen Building

Please come by to view Angad's artwork!
The wall art is a creative way to greet those interested in leveraging Allen's spectrum of device development, and those who are yet to discover what's possible inside of the Allen Buildings.

About the Allen Buildings
At the time of it's construction, the building (originally named CIS) was considered "the best example of Stanford's resident architect's progressive historicism," acknowledging the blending of 1880s architectural style with 20th and 21st century Stanford architecture. The "building was designed by Antoine Predock, an Albuquerque architect with a reputation for New Age structures that rise organically from the Southwest's desert landscape." The building is named after Microsoft's co-founder, Paul G. Allen.

Together, the Allen and Gates buildings anchor the north side of the Engineering Quad. Twenty years ago, former Dean James Gibbons said "It has been a 10-year dream of ours to draw electrical engineering and computer science – the hardware and the software ­– together in an environment surrounded by such things as the biological sciences and medicine." And by spring 2019, the Neurosciences and ChEM-H research facility is expected to be complete, just on the north side of the Allen Buildings.
