Halide: Decoupling Algorithms from Schedules For High-Performance Image Processing
We propose a new programming language for image processing pipelines, called Halide, that separates the algorithm from its schedule.

Exploiting the Analog Properties of Digital Circuits For Malicious Hardware
We show how a fabrication-time attacker can leverage analog circuits to create a hardware attack that is small and stealthy.

Powering the Next Billion Devices with Wi-Fi
We present the first power over Wi-Fi system that delivers power to low-power sensors and devices and works with existing Wi-Fi chipsets.

Authentication Using Pulse-Response Biometrics
We propose a new biometric based on the human body's response to an electric square pulse signal, called pulse-response.

Jupiter Rising: A Decade of Clos Topologies and Centralized Control in Google's Datacenter Network
We present our approach for overcoming the cost, operational complexity, and limited scale endemic to datacenter networks a decade ago.
