Patent number: 8647497Abstract: A system for hydrogen sulfide removal from a sour gas mixture including hydrogen sulfide. The sour gas mixture is reacted with a transition metal compound in a scrubber. Sulfide from the hydrogen sulfide is oxidized to form elemental sulfur and the transition metal is reduced to form a reduced state transition metal compound. An electrochemical redox reaction is performed including the reduced state transition metal compound to regenerate the transition metal compound in an electrolyzer including a power source. During the electrochemical redox reaction a voltage from the power source applied to the electrolyzer is controlled to regenerate the transition metal compound at a rate sufficient to match a flow rate of hydrogen sulfide into the scrubber or maintain a predetermined maximum hydrogen sulfide level out from the scrubber. The transition metal compound regenerated is returned to the scrubber for the reacting.Type: GrantFiled: January 17, 2012Date of Patent: February 11, 2014Assignee: University of Central Florida Research Foundation, Inc.Inventors: Cunping Huang, Franklyn Smith, Clovis A.

Patent number: 8040902Abstract: A multi-chassis router allows an administrator to deliver commands from a single interface. Additionally, the multi-chassis router presents a software image consistent with that of a standalone router and uses commands and configurations consistent with those used by a standalone router. The multi-chassis router automatically distributes, processes and responds to administrator commands a single unit, minimizing time required to administer the multi-chassis router. In effect, an administrator does not need to account for the multiple chassis configuration, and an administrator familiar with the control and commands for a standalone router can use that knowledge to effectively control the operation of the multi-chassis router.Type: GrantFiled: October 19, 2009Date of Patent: October 18, 2011Assignee: Juniper Networks, Inc.Inventors: Sriram Raghunathan, Wing Eng, Karthikeyan Ramasamy

Publication number: 20090188164Abstract: A method and system for hydrogen sulfide removal from a sour gas mixture including hydrogen sulfide includes providing an aqueous solution comprising a transition metal oxide, sulfide or carbonate compound, wherein a transition metal of the transition metal oxide is at a first valence and has at least one reduction state from the first valence. The sour gas mixture is reacted with the transition metal compound and the aqueous solution in a reactor, wherein sulfide from the hydrogen sulfide is oxidized to form elemental sulfur and the transition metal is reduced to form a reduced state transition metal compound. An electrochemical redox reaction is performed including the reduced state transition metal compound to regenerate the transition metal compound in an electrolyzer comprising an anode, a cathode, and an electrolyte membrane between the anode and cathode, wherein an oxygen including gas is added to the cathode during the electrochemical redox reaction.Type: ApplicationFiled: January 26, 2009Publication date: July 30, 2009Applicant: UNIVERSITY OF CENTRAL FLORIDA RESEARCH FOUNDATION, INC.Inventors: CUNPING HUANG, FRANKLYN SMITH, CLOVIS A.

Patent number: 6944614Abstract: A method, apparatus, article of manufacture, and a memory structure for monitoring an executed query comprising at least one execution thread is disclosed. The method comprises the steps of executing the query; and while executing the query, storing an execution trace record for each execution thread in at least one execution log file. The execution trace record comprises execution trace information including a thread ID and a time stamp for the execution thread. The execution trace information can be recalled from the execution log file and presented to a user after execution of the query to allow post mortem analysis of the query. The article of manufacture comprises a program storage device tangibly embodying instructions for performing the method steps described above.Type: GrantFiled: November 24, 1999Date of Patent: September 13, 2005Assignee: NCR CorporationInventors: Karthikeyan Ramasamy, Jie-Bing Yu

Patent number: 6678672Abstract: An On-Line Analytic Processing (OLAP) system converts queries into an operator tree comprised of a plurality of operators, wherein each of the operators is independently executed. When an exception is detected in one or more of the independently executed operators, the exception is propagated to the remaining operators of the operator tree by recycling empty data pages, piggybacking the detected exceptions on the recycled data pages, and sending the recycled data pages both upstream and downstream in the operator tree to the remaining operators of the operator tree. The propagated exceptions are delivered to the remaining operators, without interrupting the operators, at one or more points at which the operator normally reads or writes data from its input stream. Finally, the operators are terminated using a depth-first traversal of the operator tree.Type: GrantFiled: May 31, 2000Date of Patent: January 13, 2004Assignee: NCR CorporationInventors: Karthikeyan Ramasamy, Prasad Manikarao Deshpande, Amit Shukla, Jeffrey F.

Patent number: 6567804Abstract: An On-Line Analytic Processing (OLAP) system computes complex expressions and aggregations in queries by re-using and sharing subparts of the expressions and aggregations. A dependency generation phase performed by the OLAP system identifies dependencies among metrics based on the expressions, aggregations, and other metrics used by the metrics. An access plan generation phase performed by the OLAP system generates an access plan based on the identified dependencies, wherein the access plan ensures that expressions, aggregations, and metrics are computed before they are needed, and that required values and intermediate results are passed up a tree structure of the access plan until they are used or consumed by some operator. An operator assignment phase performed by the OLAP system generates operators based on the access plan, and also generates project list expressions, aggregations to be computed in each operator, and input and output tuple types for each operator.Type: GrantFiled: June 27, 2000Date of Patent: May 20, 2003Assignee: NCR CorporationInventors: Karthikeyan Ramasamy, Prasad Manikarao Deshpande, Amit Shukla, Jeffrey F.

Patent number: 6567803Abstract: An On-Line Analytic Processing (OLAP) system identifies a plurality of simultaneously computable moving aggregate functions in a query. The identified moving aggregate functions are then partitioned into sets that can be computed simultaneously based on equivalent sort expressions. Finally, the OLAP system generates an access plan that executes the partitioned sets simultaneously.Type: GrantFiled: May 31, 2000Date of Patent: May 20, 2003Assignee: NCR CorporationInventors: Karthikeyan Ramasamy, Prasad Manikarao Deshpande, Amit Shukla, Jeffrey F.
