Publication number: 20130338193Abstract: Chiral 1-(4-methylphenylmethyl)-5-oxo-{N-[(3-t-butoxycarbonyl-aminomethyl)]-piperidin-1-yl}-pyrrolidine-2-carboxamides as inhibitors of collagen induced platelet activation and adhesion The present invention provides chiral (2S)-1-(4-methyl-phenylmethyl)-5-oxo-(3S)-{N-[(3-t butoxycarbonyl aminomethyl)]-piperidin-1-yl}-pyrrolidine-2-carboxamide, and (2S)-1-(4-methylphenylmethyl)-5-oxo-(3R)-{N-[(3-t-butoxycarbonyl amino methyl)]-piperidin-1-yl}-pyrrolidine-2-carboxamide of formula 6 and 7 respectively. The present invention also relates to use of these moieties as inhibitors of collagen induced platelet adhesion and aggregation mediated through collagen receptors. The present invention provides a process for preparation of chiral carboxamides of formula 6 and 7 using the process which has advantage to avoid any racemization at the a-carboxylic center, during N-alkylation. The reagent LiHMDS is used at low temperatures to furnish methyl N-(p methylphenylmethyl)lpyroglutamate in good chiral purity.Type: ApplicationFiled: January 12, 2012Publication date: December 19, 2013Applicant: COUNCIL OF SCIENTIFIC & INDUSTRIAL RESEARCHInventors: Dinesh Kumar Dikshit, Madhu Dikshit, Tanveer Irshad Siddiqui, Anil Kumar, Rabi Sankar Bhata, Girish Kumar Jain, Manoj Kumar Barthwal, Ankita Misra, Vivek Khanna, Prem Prakash, Manish Jain, Vishal Singh, Varsha Gupta, Anil Kumar Dwivedi

Patent number: 8443080Abstract: A method and a system are disclosed for determining application dependency paths in a data center. The method and the system captures application traffic volume data on the servers with switches and monitoring agents; generates an application traffic matrix of all the components of the applications based on the application traffic volume data; estimates the number of the applications in the data center from the traffic matrix with a Rank Estimation via Singular Value Decomposition or Power Factorization Residue Errors process; and decomposes the traffic matrix into a first matrix and a second matrix with a non-negative matrix factorization process using the estimated number of applications. The first matrix represents a set of the components belonging to each of the applications and the second matrix represents the amount of traffic generated by each application over time. Any noise in the first and second matrices is removed with a concurrent volumes ratios based correlation process.Type: GrantFiled: May 4, 2011Date of Patent: May 14, 2013Assignee: NEC Laboratories America, Inc.Inventors: Min Ding, Vishal Singh, Yueping Zhang, Guofei Jiang

Publication number: 20120191843Abstract: Systems and methods for discovering a set of applications that run on a network are disclosed. In accordance with one method, aggregate traffic volumes are determined for pairs of nodes on the network over a plurality of time intervals. The method further includes building a traffic matrix denoting each of the pairs of nodes and denoting respective aggregate traffic volume histories of each of the pairs of nodes that are based on the determined traffic volumes. In addition, the traffic matrix is formulated as a combination of bases vectors that model the set of applications. The bases vectors are determined by applying a covariance matrix adaptation evolutionary strategy based on the traffic matrix. An indication of the set of applications based on the bases vectors is output.Type: ApplicationFiled: October 28, 2011Publication date: July 26, 2012Applicant: NEC Laboratories America, Inc.Inventors: Min Ding, Vishal Singh, Yueping Zhang, Guofei Jiang

Publication number: 20100318397Abstract: Architecture that provides synchronization of delegation permissions between discrete delegation models. For example, the synchronization of the delegation permissions (of a delegator and delegatee) can be performed between a delegation component of a scheduling system and a delegation component of a conferencing system such that the delegatee not only accesses the scheduling system on behalf of the delegator but also the conferencing system on behalf of the delegator. A synchronization component synchronizes the delegation permissions between the server systems (delegation components). Once synchronized, the delegatee administers the communications session, based on on-behalf-of information is validated, the delegatee can then establish the communications session.Type: ApplicationFiled: June 12, 2009Publication date: December 16, 2010Applicant: Microsoft CorporationInventors: Vishal Singh, Murtaza H.

Patent number: 7640331Abstract: A system is described for selecting web services accessible over a network (380). The system comprises a pervasive device (10), one or more servers (20) in communication with the network (380) and supporting at least one base web service (502) that provides an output in reply to a request from the pervasive device (10). The system further comprises one or more servers (20) supporting at least one extended web service (606) operable to reduce a computational load of the pervasive device (10) in an interaction with the base web service (502). An application (504) running on the pervasive device (10) evaluates attributes of a Quality of Service (QoS) model relating to interactions between pervasive device (10), a base web service (502) and corresponding expanded web service (606). The application (504) chooses whether or not to use the corresponding web service based on the evaluated attributes.Type: GrantFiled: December 29, 2005Date of Patent: December 29, 2009Assignee: International Business Machines CorporationInventors: Vishal Singh Batra, Nipun Batra

Patent number: 7213397Abstract: The invention relates to a power generation system with a continuously operating fuel reformer. Preferably, the fuel reformer is either off, warming up, or operating with an essentially constant fueling rate. Some of the reformed fuel is intermittently used to regenerate a NOx trap that treats the exhaust of an internal combustion engine. Any reformed fuel not used for other purposes is supplied to a fuel cell. The fuel reformer does not shut down between NOx trap regeneration cycles except when the engine is also shut down. The invention substantially eliminates issues of reformer response time as they relate to NOx trap regeneration.Type: GrantFiled: February 7, 2005Date of Patent: May 8, 2007Assignee: Eaton CorporationInventors: Haoran Hu, Subbaraya Radhamohan, Karen Evelyn Bevan, James Edward McCarthy, Jr., Jiyang Yan, Johannes W.
