Abstract: A disclosed system, method and computer readable storage medium includes mechanism for controlling cascade price movements in an electronic trading system. Price limits control the prices at which traders can place orders. An upper price limit prevents traders from placing orders above the upper limit and a lower price limit prevents traders from placing orders below the lower limit. The gap between the upper limit and the indicative marked price as well as the gap between lower limit and the indicative market price is controlled so as to cause a breaking effect on very rapidly changing market price.

Abstract: A laser communication network implemented with multi-chroic filters that are able to partition signals from a band of wavelengths into different sub-bands that enable more than one relay terminal to interconnect users (i.e., sources and sinks of traffic) is provided. A band of wavelengths may be partitioned to enable users to communicate with relay satellites, and relay satellites to communicate with one another, using a predefined set of transmission and reception wavelengths regardless of which particular relay is in the communication session. In other words, embodiments support both relay satellites and user satellites by constructing distinct passbands for relay-borne terminals and the same passbands for users.

Abstract: A class of robots specifically adapted to climb periodic lattices. These “relative robots” are designed for a specific lattice structure and use the regularity of the structure to simplify path planning, align with minimal feedback, and reduce the number of degrees of freedom (DOF) required to locomote. These robots can perform vital inspection and repair tasks within the structure that larger truss construction robots cannot perform without modifying the structure. A particular embodiment is a robot designed to traverse a cubooctahedral (CubOct) cellular solids lattice using only two motions: climbing and turning.

Abstract: A supercritical water oxidation-flame piloted vortex reactor has a hydrothermal flame produced within the interior of the reactor fed by a fuel including a waste water stream, and has a subcritical wash stream, including water below its critical point, that creates an upward helical flow in the material within the reactor. The hydrothermal flame and upward helical flow produce within the reactor a supercritical core region, a subcritical outer region around the core region, and a transcritical intermediate region between them. The upward helical flow serves to transfer precipitated ionic compounds out of the supercritical core region, through the transcritical intermediate region, and into the subcritical outer region where they re-dissolve. A processed flow, including purified water, is removed from an upper portion of the supercritical core region by an aspirator.
