Item The Expansion of Digital Microfluidic Systems(2021) Anderson, ChaseDigital microfluidics (DMF) is a technology that allows for movement and manipulation of liquid using electricity. By charging and discharging conductive pads upon a grid, one is able translate, split, and mix droplets to perform conventional wet lab operations. By minimizing handling time, chemical dangers, and laboratory wastes (e.g. pipette tips); DMF stands at the forefront of modern bio-chemical implementations. Most DMF prototypes/platforms utilize a single grid space, and this should change. In hopes to connect 4 ,16 , 64, or n-many grids for that matter; current DMF designs do not have required infrastructure. Each pad must be charged to upwards of 300 volts, so hardware, separate from the brains of the system, is required to facilitate normal operation. Like the heart, DMF platforms operate on beats and must be synchronous. Often, a microcontroller (Arduino, PIC, STM32) is used; however, microcontrollers operate sequentially, meaning each instruction given to the machine must execute one after the other. If one wished to parallelize the process of DMF, a separate computing paradigm must be used. Enter the FPGA (Field Programmable Gate Array). Being able to process multiple lightweight channels of data at a time, the FPGA enables the end user to have thousands if not millions of droplets moving synchronously across hundreds of grid systems. The research task was to find an elegant solution to the problem of parallelizing DMF systems using FPGAs.Item Oral history interview with Robert Braden(Charles Babbage Institute, 2014-11-19) Braden, RobertThis interview with internet pioneer Robert (“Bob”) Braden briefly covers his education in physics before concentrating on his long and distinguished career in computer science. He served at the computation centers of Carnegie Institute of Technology and Stanford University before joining UCLA as Manager of Programming (1968-1974) and later serving (1975-1986) as Project Director for Software Research. In 1986 he became a Supervising Computer Scientists and Project Leader at the Computer Networks Division of USC’s Information Sciences Institute, where he continues to serve. From its inception (in 1981) he was a member of Internet Activities Board (IAB) and served as IAB Executive Director for a half decade. He was long-term member and Chair of the End-to-End Task/Force Research Group (1984-2005). In these roles he made fundamental contributions to internet protocol standards. Braden is an ISI Fellow and an ACM Fellow.
