Publication number: 20200134110Abstract: Model elements of an executable model, representing a physical system, are partitioned into one or more linear portions and one or more nonlinear portions. Simulating behavior of the physical system, by executing the model, includes, for each of multiple simulation time intervals, for a first nonlinear portion, computing a correlation matrix characterizing noise associated with one or more ports of the model. A scattering matrix corresponds to a portion of the physical system represented by the first nonlinear portion without accounting for any noise within the portion of the physical system. The correlation matrix is derived from the scattering matrix based on noise within the portion of the physical system. Noise sources representing noise within the portion of the physical system are identified based on the correlation matrix. At least one characteristic of noise associated with each noise source is computed, and noise characteristics are output at selected ports.Type: ApplicationFiled: January 22, 2019Publication date: April 30, 2020Inventors: Alon Ludwig, Ebrahim Mestchian, Pieter Mosterman, Mark Reichelt

Patent number: 9195504Abstract: A method for data transfer in a data processing system, and corresponding system and machine-readable medium. One method includes receiving by the data processing system a request for a data structure from a calling process, and splitting the data structure into a plurality of substructures by the data processing system. That method includes transferring the plurality of substructures to the calling process by the data processing system, wherein at least two of the substructures are transferred in parallel, and maintaining a transfer state for each substructure in the data processing system.Type: GrantFiled: September 21, 2009Date of Patent: November 24, 2015Assignee: Siemens Product Lifecycle Management Software Inc.Inventors: John Staehle Whelan, Mark Ludwig

Patent number: 8886593Abstract: A method for data transfer in a data processing system, and corresponding system and machine-readable medium. One method includes receiving by the data processing system information relating to a data structure to be transferred, where the data structure includes a plurality of elements. Each element in the structure is linked to at least one other element in the structure. The method also includes selecting by the data processing system a group of the plurality of elements, the group including at most a predetermined maximum number of elements. The method further includes transferring by the data processing system the group of elements to a destination. The method also includes assigning by the data processing system the elements of the plurality of elements that are not in the group of elements to one or more substructures. At least one substructure is assigned two or more direct child nodes of transferred nodes.Type: GrantFiled: February 1, 2011Date of Patent: November 11, 2014Assignee: Siemens Product Lifecycle Management Software Inc.Inventors: John Staehle Whelan, Mark Ludwig, Dheiveekan Krishnamurthy, Pragyaditya Barat, Ravi Rajagopal

Patent number: 8166208Abstract: A system, method, and computer readable medium. A method includes setting a maximum translation delay. The method includes, while a current delay is less than the maximum transfer delay, repeatedly performing the steps of searching for an additional transfer having a same source and target as a current transfer, and when an additional transfer is found, adding the additional transfer to a transfer list that identifies transfers to be made together. The method includes performing a transfer of the transfers identified by the transfer list when the current delay has met or exceeded the maximum transfer delay.Type: GrantFiled: April 26, 2010Date of Patent: April 24, 2012Assignee: Siemens Product Lifecycle Management Software Inc.Inventors: John Staehle Whelan, Mark Ludwig

Patent number: 7631320Abstract: A method and apparatus for performing actions while selecting objects on a user interface display. A user may select a first item in an area of a display controlled by a first process and drag that item to a second area on a display controlled by a second process. The second process may negotiate with the first process to provide certain data types, and based upon those data types, the second process will determine a list of actions in hierarchical fashion which may be performed upon the data. Such actions may include, but are not limited to, printing, sending electronic mail, and performing other actions in the computer system. Alternative and primary actions may also be specified by a user, such as by selecting various keys on a keyboard or other input device. Further, a user may specify that the second process display a list of actions which may be performed upon the selected item and allow the user to select an action from a list.Type: GrantFiled: August 3, 2004Date of Patent: December 8, 2009Assignee: Apple Inc.Inventors: Mark Ludwig Stern, Robert George Johnston, Jr., Elizabeth Ann Robinson Moller
