![]() Roseline is a key component in the NSF’s longstanding support for CPS research and education, an area in which the agency has invested nearly $200 million over the last five years. In addition to Srivastava and Pamarti, the Roseline team includes co-principal investigator Rajesh Gupta (UC San Diego) João Hespanha (UC Santa Barbara) Ragunathan Rajkumar and Anthony Rowe (Carnegie Mellon University), and Thomas Schmid (University of Utah). Project leaders also plan to integrate CPS and timing components into graduate and undergraduate course materials and engage in outreach efforts to pre-college students, including the Los Angeles Computing Circle, which focuses on teaching real-world applications of computer science to students from local high schools. The group seeks to develop new clocking technologies, synchronization protocols and operating system methods, as well as control and sensing algorithms. Over the five-year span funded by NSF, the Roseline team will rethink and reengineer how the knowledge of time is handled across a computing system’s hardware and software. Still, many other areas of clock technology are still ripe for development, including CPS applications, which play a critical role in our physical and network infrastructure and need precise timekeeping to properly connect computers, communications technologies, sensors and actuators to objects and. This, in turn, created new opportunities - and even entirely new industries - and led to the development of mobile navigation systems. For example, advances in distributed clock synchronization technology enabled Global Positioning System (GPS) satellites to precisely measure distances. From pendulums to atomic clocks, the accurate measurement of time has helped drive scientific discovery and engineering innovation. Time has always been a critical issue for science and technology. “Through the Roseline project, we will drive cyber-physical systems research with a deeper understanding of time and its trade-offs, and advance the state-of-the-art in clocking circuits and platform architectures,” Srivastava said. UCLA associate professor of electrical engineering Sudhakar Pamarti is also a member of the team, which will include electrical engineering and computer science faculty from UC San Diego, UC Santa Barbara, Carnegie Mellon University and the University of Utah. ![]() ![]() Mani Srivastava, a professor of electrical engineering at UCLA’s Henry Samueli School of Engineering and Applied Science, is the project’s principal investigator. ![]() Timekeeping presents a particular challenge in this emerging field, which depends on precise knowledge of time in order to infer location, control communications and accurately coordinate activities in a broad and growing range of applications, from autonomous cars and aircraft autopilot systems to advanced robotic and medical devices, energy-efficient buildings and an array of other industrial initiatives. The research team’s Roseline project, headquartered at the UCLA Henry Samueli School of Engineering and Applied Science, will work to improve the accuracy, efficiency, robustness and security with which computers maintain their knowledge of physical time and synchronize it with these networked devices. #TIMEKEEPER CPS SOFTWARE#The National Science Foundation has announced a $4 million “Frontier” award to a UCLA-based team that will tackle the challenge of timekeeping in cyber-physical systems (CPS) - often called the “Internet of Things” - in which objects and devices are equipped with embedded software and are able to communicate with and be controlled by wireless digital networks. ![]()
