    摘要: A solid-state device chip including diodes (generating a higher or lower frequency output through frequency multiplication or mixing of the input frequency) and a novel on-chip diplexing design that allows combination of two or more multiplier or mixer structures operating at different frequency bands within the 50-5000 GHz range within a same chip and/or waveguide. The on-chip diplexing design consists of a single-substrate multiplier chip with two or more multiplying structures each one containing 2 or more Schottky diodes. The diodes in each structure are tuned to one portion of the target frequency band, resulting in the two or more structures working together as a whole as a large broadband multiplier or mixer. Thus, an increase in bandwidth from 10-15% (current state-of-the-art) to at least 40% is achieved. Depending on the target frequencies, each subset of diodes within the chip can be designed to work either as a doubler or a tripler.

    摘要: A method and system provide the ability to estimate the vulnerability of a repairable infrastructure system. A survival curve is constructed for one or more assets. A rehabilitation plan is prescribed for one or more failure states of the repairable infrastructure system. A cost estimation model is constructed for costs associated with the repairs for each of the failure states. A planning basis is specified. A multiple probability simulation is conducted that estimates a potential restoration cost for a possible failure. The simulation is repeated to acquire a distribution of potential restoration costs. A vulnerability estimation is determined and provided based on the distribution.

    摘要: A computer implemented method or system for creating a route for navigating a transit hub or plaza using an application executing on a user's mobile device. The application accesses a tessellated map comprising first tiles each including a different area of interest on the map; and second tiles including a walkable area connecting the different areas of interest. The application highlights one of the first tiles including one of the different areas of interest selected using input from the user; highlights one of the second tiles including a location of the mobile device on the map; and highlights a series of the second tiles linking the location to the one of the areas of interest. A method of creating the tessellated map is also disclosed.

    摘要: An apparatus, method and computer program product for estimating as-a-Service (aaS) query prices in a relational database management system (RDBMS). An optimizer of the RDBMS inserts an EXPLAIN modifier into a query, wherein the EXPLAIN modifier results in the optimizer generating a summary of a query execution plan for the query that includes one or more cost estimates for the RDBMS to perform the query. A price estimate for the query is then generated based on the cost estimates, wherein the price estimate is generated using one or more configurable pricing formulae. The price estimate is merged into the summary of the query execution plan for the query. Moreover, a price guarantee may be generated for the price estimate, wherein the price guarantee is honored when the query is subsequently invoked for execution by the RDBMS.
