The Georgia Institute of Technology is a public research university in Atlanta, Georgia, in the United States. It is a part of the University System of Georgia and has satellite campuses in Savannah, Georgia; Metz, France; Athlone, Ireland; Shanghai, China; and Singapore.The educational institution was founded in 1885 as the Georgia School of Technology as part of Reconstruction plans to build an industrial economy in the post-Civil War Southern United States. Initially, it offered only a degree in mechanical engineering. By 1901, its curriculum had expanded to include electrical, civil, and chemical engineering. In 1948, the school changed its name to reflect its evolution from a trade school to a larger and more capable technical institute and research university.Today, Georgia Tech is organized into six colleges and contains about 31 departments/units, with emphasis on science and technology. It is well recognized for its degree programs in engineering, computing, business administration, the science, architecture, and liberal arts.Georgia Tech's main campus occupies part of Midtown Atlanta, bordered by 10th Street to the north and by North Avenue to the south, placing it well in sight of the Atlanta skyline. In 1996, the campus was the site of the athletes' village and a venue for a number of athletic events for the 1996 Summer Olympics. The construction of the Olympic village, along with subsequent gentrification of the surrounding areas, enhanced the campus.Student athletics, both organized and intramural, are a part of student and alumni life. The school's intercollegiate competitive sports teams, the four-time football national champion Yellow Jackets, and the nationally recognized fight song "Ramblin' Wreck from Georgia Tech", have helped keep Georgia Tech in the national spotlight. Georgia Tech fields eight men's and seven women's teams that compete in the NCAA Division I athletics and the Football Bowl Subdivision. Georgia Tech is a member of the Coastal Division in the Atlantic Coast Conference. Wikipedia.

In a method for clients to transmit data via a shared medium network, a schedule assigns time slots to individual clients. A collision avoidance scheme determines an offset time to begin transmitting data, which upon expiration, a client senses if any of the clients is transmitting. If a second client is transmitting, then each client sets a first time slot assigned to the second client on the transmission schedule as a starting time slot. The clients track the schedule and transmit to the access point during the next time slot assigned to each client. If no other client is transmitting, then a client transmits data to the access point, sets the first time slot assigned to it as the starting time slot. The schedule is tracked by the clients and they transmit data to the access point during each successive time slot assigned to them.

An authenticating circuit includes a first and second challenge vector input, a first and second highly variable process-dependent circuit and a logic circuit. The first highly variable process-dependent circuit receives a first vector from the first challenge vector input and generates a first output that is a function of the first vector and at least one process-dependent feature of a component of the first highly variable process-dependent circuit. The second highly variable process-dependent circuit receives a second vector from the second challenge vector input and generates a second output that is a function of the second vector and at least one process-dependent feature of a component of the second highly variable process-dependent circuit. The logic circuit generates a response output that is a function of the first output and the second output. The function operates so that the response output is independent of environmental conditions of the authenticating circuit.

Various embodiments of the invention are detection systems and methods for detecting call provenance based on call audio. An exemplary embodiment of the detection system can comprise a characterization unit, a labeling unit, and an identification unit. The characterization unit can extract various characteristics of networks through which a call traversed, based on call audio. The labeling unit can be trained on prior call data and can identify one or more codecs used to encode the call, based on the call audio. The identification unit can utilize the characteristics of traversed networks and the identified codecs, and based on this information, the identification unit can provide a provenance fingerprint for the call. Based on the call provenance fingerprint, the detection system can identify, verify, or provide forensic information about a call audio source.

Apparatus, including an insertion tube, configured to be inserted into a body cavity and having a first lumen having a first lumen diameter and a distal opening, and a tubular channel, having a second lumen and an outer channel diameter smaller than the first lumen diameter, inserted into the first lumen. The apparatus includes a support structure, configured to be passed through a space between an inner wall of the insertion tube and an outer wall of the tubular channel to the distal opening in a folded state and to unfold, upon exit of the support structure through the distal opening, in a direction transverse to the first lumen to reach a support dimension that is greater than the first lumen diameter. A plurality of planar two-dimensional arrays of ultrasonic transducers are supported by the support structure, the arrays having transverse dimensions less than the first lumen diameter.

A silicon-based anode comprising silicon, a carbon coating that coats the surface of the silicon, a polyvinyl acid that binds to at least a portion of the silicon, and vinylene carbonate that seals the interface between the silicon and the polyvinyl acid. Because of its properties, polyvinyl acid binders offer improved anode stability, tunable properties, and many other attractive attributes for silicon-based anodes, which enable the anode to withstand silicon cycles of expansion and contraction during charging and discharging.

Systems and methods for controlling a swarm of mobile robots are disclosed. In one aspect, the robots cover a domain of interest. Each robot receives a density function indicative of at least one area of importance in the domain of interest, and calculates a velocity vector based on the density function and a displace vector relative to an adjacent robot. Each robot moves to the area of importance according to its velocity vector. In some aspects, the robots together perform a sequence of formations. Each robot mimics a trajectory as part of its performance by switching among a plurality of motion modes. Each robot determines its next motion mode based on a displacement vector relative to an adjacent robot.
