Students Prototype The Future

If you’re looking for the next big idea in emerging media, such as virtual and augmented reality (VR/AR) and artificial intelligence (AI), there is no better place to look than universities like NYU. This reality is one that NYC Media Lab understands quite well. Tapping into New York’s student talent pool, the organization helps students develop prototypes that will disrupt and advance sectors such as media, technology, healthcare, retail, advertising, and more.

This prototyping of the future was on full display at the recent Demo Day of the Verizon Connected Futures Prototyping & Talent Development Program. Sponsored by NYC Media Lab and Verizon, the Connected Futures program supported 12 student teams who created projects within the areas of AR design and marked tracking, social VR/AR, the intersections of AR and AI, and the next generation in wireless technology. Gaining expertise and insight from the team at Verizon Envrmnt, students from across New York universities, including NYU Tandon School of Engineering, The New School, and Columbia University, designed, iterated and built their ideas into prototypes over six weeks. The program also benefits from support from the Center for Advanced Technology in Telecommunications and Distributed Information Systems (CATT).

“Through our Verizon Connected Futures program, we have a dozen new ideas at various stages of realization,” Justin Hendrix, Executive Director of NYC Media Lab, shared at the Demo Day. “We’re experiencing what’s possible right now with new technology.” The 12 teams designed products and services that span various industries, including education, transportation, retail, music, psychology, and more.

Driven by their passion for innovation and using technology to serve society, three NYU Tandon student teams shared their prototypes to a rapt audience of industry experts at the Demo Day.

Navigating the New York City subway system can be difficult, so the team behind CitytravelAR created an augmented reality wayfinding platform that allows you to use your smartphone to easily get around the city. “Using subway signage as AR markers, users would be able to not only find out the best train route for their journey, but also learn about local communities in and around the station area,” Subigya Basnet said. Basnet alongside his teammates and fellow Integrated Digital Media graduate students Vhalerie Lee and Baris Siniksaran hope their application can function within building smart cities using AR technology to merge commuting and community. “For all of us, NYU Tandon gave us the platform to begin this dive into VR/AR production and development,” Basnet shared, as he, Lee, and Siniksaran have all created projects like the “Game of Thrones” AR narrative experience and WAVR. “The opportunity to experiment our ideas encouraged us to take up opportunities, like the Verizon Connected Futures Challenge.”

ARSL

Heng Li and Mingfei Huang demonstrate ARSL

Computer science students Zhongheng (Heng) Li, Jacky Chen, and Mingfei Huangdebuted their mobile app that provides real-time sign language interpretation to help people communicate with each other more easily. With computer vision, cloud computing, and AR, ARSL uses a smartphone’s camera to capture and translate sign languages into the other user’s native spoken language, and instantaneously records spoken language and translates into sign. “This accessible solution empowers people to get connected,” Li said, adding that his team has a shared passion for using emerging tech for social good. With the millions of people around the world who are deaf or hearing impaired, this app could help people book appointments, explain their symptoms to doctors, or ask for directions, all through a translator in the palm of their hands.

CATT Professor Claudio Silva Receives Emmy Award for His MLB Visual Analytics Tool

There may not have been a red carpet involved, but Professor of Computer Science and Engineering Claudio Silva had cause for celebration when the National Academy of Television Arts & Sciences (NATAS) announced the winners of the 2018 Technology and Engineering Emmy Awards, which honor breakthroughs in technology that have a significant effect on television engineering.

Silva is the developer of a visual analytics tool now being used in Major League Baseball (MLB) stadiums across the country as part of the Emmy-winning Statcast, which combines the tool with a radar-based ball-tracking system and an optical player-tracking solution.

Silva’s tool — which he dubbed Baseball 4D when he presented it at the 2014 Institute of Electrical and Electronics Engineers Visualization Conference — provided the ability to analyze each and every play on the field for the first time in sports history, allowing fans and industry officials to answer previously unanswerable analytics questions like where players should be positioned to best catch a ball traveling at a particular velocity or which players were most likely to accurately anticipate a pitch’s trajectory.

Silva collaborated with MLB Advanced Media on the development of the system — which involves groups of high-performance cameras installed throughout the ballpark along with software that produces highly interactive visualizations of the game in unprecedented detail. MLB Advanced Media shares the Emmy, which will be presented on April 8th, 2018 at a ceremony in Las Vegas, with the company ChyronHego, which was responsible for Statcast’s optical player-tracking equipment, and TrackMan, the creators of its radar-based ball-tracking system.

The Emmy win was not the only time in recent weeks that Silva had made a splash in the media. In Rio to visit the Fundação Getúlio Vargas, a well-regarded institution of higher learning, he was interviewed about machine learning and data visualization by the Brazilian publication O Globo.

While the Emmy may recognize the significance of visual analytics in sports, his research into data visualization has far-reaching applications and potentials, from building software in smart cars to creating interactive urban design models.

A Robust Pipeline to STEM

Jemima Costanza is now on a pre-med track. Maeve Farrell has set her sights on a career at a major research university. Edward Huang and Vicente Gomez are studying computer science as undergraduates. Amaya Munoz foresees a future as an electrical and computer engineer. Jamie Monroy views biotechnology as an exciting career path. The list could go on and on. After taking part in the Applied Research Innovations in Science and Engineering (ARISE) program as high school students, person after person begins to picture a career in the world of science, engineering, or technology one day.

Funded by a grant from the Pinkerton Foundation, ARISE was launched in 2013 by NYU’s Center for K12 STEM Education, with the aim of inviting rising juniors and seniors from New York City high schools into university labs to engage in high-level research. The seven-week program introduces them to the scientific method, data collection and analysis, lab safety, and ethics, and they are expected to make solid and useful contributions to their labs’ research objectives and daily operation. “We were individually mentored by graduate students and post-docs,” Gomez — who participated in ARISE in 2015 but whose connection to Tandon’s summer offerings stretches back even further, to when he participated in a program called Science of Smart Cities as a middle school student — recalls. “They did not sugarcoat the rigor a scientific career demands, and they didn’t take it easy on us simply because we were still in high school.”

ARISE — which recruits many students from demographic groups generally underrepresented in STEM disciplines, including women, students of color and those from low-income backgrounds — hosted 48 participants this summer, embedding them in a wide variety of faculty labs (see below) and assigning them Tandon graduate and post-doctoral mentors.

The resulting projects, presented to the public at the end of the program, ranged from assessing DNA extraction methods from museum specimens, to building sensors to study noise pollution in the city, to testing the effects of temperature and orientation on 3D printed parts and more.

Jason Mei of Stuyvesant High School and Xue Ye Lin of Brooklyn Tech, for example, worked with Professor of Chemical and Biomolecular Engineering Miguel Modestino, who recently garnered a 2017 Global Change Award from the H&M Foundation for his development of a method of using solar energy and plant waste, rather than fossil fuel, to synthesize nylon. The pair — both of whom aspire to study chemical engineering once they are in college — fabricated custom solar arrays that may one day be employed to scale up Modestino’s process. “You might think that high school students would not be capable of making any meaningful or practical contributions in a university lab, but these two have proven you wrong,” Modestino says. “Their help was invaluable, and I’d be happy to have many more like them.”

Like Modestino, many of the professors who volunteered to host ARISE students were amply impressed. For proof, look no further than the figures compiled by Ben Esner, the head of the Center for K12 STEM Education.

“This year, an unprecedented 16 labs and faculty members have asked their ARISE students to continue working on their research during the school year, even though the program has officially ended for the summer,” he explains. “Out of 48 students, 26 will be staying on, furthering their own learning, contributing to their mentors’ research, and proving that programs like this are an invaluable way to get and keep young people interested in STEM.”

Another Way to Spend the Summer

Pedro Velazquez took part in ARISE in the summer of 2015, back when he was a rising junior at Forest Hills High School in Queens. He had long been fascinated by science and studied biology at his school’s Carl Sagan Science/Math Honors Academy. He jumped at the chance to spend the summer at Tandon, conducting research in Professor Maurizio Porfiri’Dynamical Systems Lab, where he did image analysis on novel polymers that change color when stressed — an area with great practical applicability in fields like infrastructure testing.

“The experience completely changed how I perceived being a scholar and researcher,” he recalled. “I used to think that to ‘know’ something you simply had to read about it and be able to summarize it. That was a real misperception. Almost anyone can memorize something by rote and spit it out. It’s an entirely different thing to gain a deep understanding of the topic and be able to present it to others concisely and clearly.”

While he enjoyed his time at Tandon and missed being in the lab here, this past summer, Velazquez attended a program of a different sort: one aimed at rising Cornell freshmen. He is attending the Ithaca school this semester and had been accepted into its demanding Summer Research Scholars Program. “Thanks to ARISE,” he says, “I knew I could do it and more than hold my own.”

NYU Wireless Researchers Build Emulator to Test 5G Networks

NYU Wireless teamed with the Center for Advanced Technology in Telecommunications (CATT) to build a wireless emulator for 5G systems. The emulator recreates both the wireless channel and the phased-array antennas. It can be used for transmitter and receiver devices so researchers can understand how 5G will perform in different environments and weather conditions.

According to a blog post from NYU Wireless, researchers used commercial off-the-shelf (COTS) hardware from National Instruments coupled with emulator software that is based upon reference designs available to the academic researchers.  By using COTS, the researchers said they can lower the cost and complexity of the testing.

Young Scholar on the Rise with Help from K-12 STEM Program

Since its inception in 2013, the Applied Research Innovations in Science and Engineering (ARISE) program at the NYU Tandon School of Engineering has been nurturing NYC’s best young STEM talent. The full-time, seven-week program offers college-level workshops and seminars for New York high school students, as well as high-level research experience in participating NYU faculty labs and mentoring by a graduate or postdoctoral student.

Budding researcher and Stuyvesant High School student Caleb Smith-Salzbergrecently joined a research team headed by Professor Shivendra Panwar that centers on innovations in wireless technologies. Never did he imagine that his first research paper would be accepted for publication and presentation at the 2017 IEEE INFOCOM, a top-ranked conference on networking sponsored by the Institute of Electrical and Electronics Engineers.

Smith-Salzberg is the first-listed author of the paper, an honor that would be unusual even for an undergraduate student. In “Bridging the digital divide between research and home networks,” he and his co-authors describe efforts to make it easier for researchers to improve the performance of networked applications and services on real-world networks. Their tool, which makes test networks more representative of typical home broadband connections, debuted at IEEE INFOCOM’s International Workshop on Computer and Networking Experimental Research Using Testbeds (CNERT) on May 1, 2017 in Atlanta, Georgia. Smith-Salzberg and his ARISE mentor Fraida Fund, a doctoral candidate in the Department of Electrical and Computer Engineering, also exhibited their work at NYU Tandon’s Research Expo in April.

Smith-Salzberg worked extensively last summer with Fund, who gives him due credit for his contributions. “He did most of the work developing the tool described in the paper over the summer, when he was working with us full-time,” Fund said. “Then, we worked on the paper draft together over the first half of this academic year. Every week, he came to Tandon once a week  after school, and we worked on the text together.”

Smith-Salzberg found his experience in the ARISE program gratifying and encourages anyone lucky enough to take part in the program to make the most of it. “I was treated by everyone at the lab as an equal member of the team,” he said. “I presented at the weekly meetings, and in my last week I presented to a larger group, which included Professor Panwar. This experience at a real workplace environment is very special, and there are not many programs that offer such an opportunity.”

Their research was supported by the National Science Foundation Graduate Research Fellowship Program, the New York State Center for Advanced Technology in Telecommunications (CATT)NYU Tandon School of Engineering’s Center for K-12 STEM Education, and the Pinkerton Foundation.

NYU Researchers Develop New Paradigm for 5G Emulation

Researchers at CATT and NYU Wireless have built the world’s first wireless emulator suitable for 5G systems that feature massive bandwidths and hundreds of antenna elements. In this unique patented design, the solution emulates not only the wireless channel, but also the beamformers (or phased-arrays) on both the transmitter and receiver devices under test (DUTs). This joint emulation of the beamformer and the wireless channel is the key enabling technology that allows for faster development cycles, while significantly lowering the hardware cost and complexity of the emulator. The project was led by post-doctoral fellow Dr. Aditya Dhananjay, and was supervised by faculty members Dr. Sundeep Rangan and Dr. Dennis Shasha. The project was enabled by a generous hardware donation of commercial off-the-shelf (COTS) components from National Instruments. The NYU researchers are also making the emulator software available to academic researchers for free, along with reference TX and RX DUT software designs.

As the 5G standardization process gathers steam, one of the critical challenges lies with the design and testing of the new generation of wireless systems. A key component of this testing process is channel emulation, wherein a channel emulator is used to simulate a configurable wireless channel between the transmitter and receiver devices under test. An emulator can be configured to reproduce a variety of wireless scenarios such as urban microcell, rural macrocell, mobility patterns, different weather conditions, and so on. Channel emulation offers reproducibility and enables the validation and testing of designs under worst-case scenarios, and is therefore an essential step before the time-consuming and expensive over-the-air (OTA) and field testing.

In the existing emulation paradigm, the transmitter and receiver devices under test (TX and RX DUTs) are connected using cables to a channel emulator as shown in Figure 1. The RF signal vector from the TX DUT (one signal from each antenna element) is cabled through to the emulator. The wireless channel to be emulated is generally described via multipath fading profile which can be configured to reproduce measured traces or standard profiles such as in the 3GPP models. The output from the emulator is the signal vector, which is then cabled through to the RX DUT using one cable for each antenna element.

Basically, the job of a channel emulator is to transform the input signal vector into the output signal vector. Due to the benefits offered, channel emulators have been widely used for Wi-Fi, 3G, and 4G LTE development, and are indeed a staple on any wireless research lab bench. However, there are no commercial emulators available that are suitable for upcoming 5G millimeter wave (mmWave) systems.

These upcoming 5G mmWave systems will differ from existing 4G systems in two main ways: a) the number of antenna elements are increased by an order of magnitude due to the use of mmWave phased arrays; and b) the bandwidths that these systems operate over is also increased by at least an order of magnitude. These differences make the existing emulation paradigm unsuitable for 5G mmWave systems for a variety of reasons. First, phased-array antenna elements cannot be connected to cables. Second, the large number of antenna elements makes the hardware cost of building the emulator prohibitively expensive. Third, the computational complexity is increased by multiple orders of magnitude due to the large number of antenna elements and large bandwidth. These are the reasons that no commercial 5G mmWave emulators exist today. In order to support hundreds of antenna elements and several gigahertz of real-time bandwidth, current designs would need to resort to prohibitively expensive frequency stitching.

The NYU emulator solves these challenges by defining a fundamentally new emulation paradigm for 5G mmWave systems. In this paradigm, the emulator not only emulates the wireless channel, but also the multi-antenna beamformers on both the TX and RX DUTs as contrasted in Fig. 2(a) and 2(b). The TX and RX DUTs share their instantaneous beamforming vectors with the emulator, so that the beamforming operations can be emulated. The TX DUT sends the emulator the pre-beamformed signal as opposed to the post-beamformed signal vector. Symmetrically, the emulator sends the RX DUT the post-beamformed signal as opposed to the output pre-beamformed signal vector.

The emulator is flexible, and can support the signals in baseband, IF, or in RF, depending on the DUT configuration. By combining the emulation of the multi-antenna beamformers on the DUTs with the emulation of the wireless channel (the key patented technology), the computational complexity and hardware cost of the emulator are greatly reduced. Another key benefit in this new emulation paradigm is that researchers can experiment over different theoretical phased-array designs, further accelerating the research and development in protocols at all layers of the protocol stack.

The NYU team has already demonstrated this emulator with 64-element DUTs and more than 2 GHz bandwidth at two major trade-shows: the Brooklyn 5G Summit, and at a workshop at NI Week in Austin. The implementation of this emulator was supported by a very generous hardware donation from NI to NYU.

Yong Liu Named a Fellow of the IEEE

Yong Liu — a professor of electrical engineering at the NYU Tandon School of Engineering and a faculty member of the Center for Advanced Technology in Telecommunications (CATT) and NYU WIRELESS — has been named a fellow of the Institute of Electrical and Electronics Engineers (IEEE), the world’s largest technical professional association, for contributions to multimedia networking. He is the 100th recipient of that honor at NYU Tandon.

Liu, who has published more than 100 papers in major journals and conferences, was recognized for seminal work in the measurement, modeling, analysis, and design of multimedia networking systems, which now dominate online traffic and which crucially impact the performance and stability of the global Internet.

Because most commercial multimedia applications use proprietary protocols and encrypt their data and signaling, there had been very limited public information about their design choices and the Quality of Experience (QoE) delivered to users, and Yong’s research filled this knowledge gap, providing valuable insights into system architecture, design, performance, and network impact. He is also active in the field of peer-to-peer (P2P) technology, which leverages networking, computation and storage resources available on end systems to deliver a wide range of scalable network services and which is now a core component in many modern Internet applications.

Notably, Liu devised novel real-time bandwidth estimation and video adaptation algorithms that were recently adopted by Tencent WeChat, China’s exceptionally popular online social network platform, significantly improving the experience of WeChat’s 650 million monthly active users around the world.

“It is always a proud moment when an august organization like the IEEE elevates one of our faculty members to Fellow status,” Dean Katepalli Sreenivasan said. “This honor indicates the high quality of his research and his commitment to solving real-world problems. I congratulate him on receiving this well-deserved recognition.”

Liu holds a master’s degree from the University of Science and Technology of China and a doctorate from the University of Massachusetts, Amherst. Among his many other honors are a National Science Foundation CAREER Award, given to young researchers who exemplify the role of teacher-scholar, and multiple best-paper awards at such events as the Association for Computing Machinery Internet Measurement Conference and the IEEE Conference on Computer Communications (INFOCOM).

His latest research involves augmented reality and virtual reality, which are predicted to become the next generation of “killer apps” when fifth-generation (5G) mobile is widely available to consumers.

The IEEE is dedicated to advancing technological innovation and excellence for the benefit of humanity. The group has more than 400,000 members around the globe, only a small fraction of whom are honored with the designation of fellow.
