Abstract: Facilitating interaction with a spreadsheet it provided. One or more input cells of a spreadsheet displayed on a display device of a computer system are automatically detected. One or more candidate cells of the spreadsheet are presented for selection, as candidates for inclusion in an interface for display on the display device in conjunction with the spreadsheet, the one or more candidate cells including the detected one or more input cells. Based on a selection of at least one cell, of the one or more candidate cells, for inclusion in the interface, the selected at least one cell is displayed in the interface, where the selected at least one cell includes at least one input cell of the one or more candidate input cells.

Abstract: A method and Web server for verifying a Web service request originating from a Web page is provided. The method includes matching the Web service request with a Web service. A sequence ID contained in the request is identified. The Web service request is verified if the identified sequence ID does not correspond with a previous sequence ID for the matched Web service. Additionally, the Web service does not verify a same Web service request twice.

Abstract: A system, method and program product for document navigation by usage location in a document editing application. A document map divides a document into a plurality of document elements and a user interaction dataset records weights and durations of user interactions for each of the document elements over a plurality of user interactions. A usage calculator calculates a usage value for each of the document elements based on weights and duration. The usage value for each of the document elements is used generate an element selection interface to selectively display a relevant document element on a document navigation display.

Abstract: The method, computer program product and computer system may include a computing device that receives at least one course objectives. The computing device may receive a course syllabus which may comprise a plurality of topics and define one or more topic dependencies between the plurality of topics. The computing device may receive an initial class schedule for the plurality of topics. The computing device may receive a student assessment of a first topic on the initial class schedule and may score the assessment of the first topic and select a second topic based on the topic dependencies. The computing device may determine a second assessment score on a second topic using one or more factors. The computing device may determine at least one course schedule option using the at least one course objective, the at least one student assessment score of the first topic, and the second assessment score.

Abstract: Programmatically generating a mixed integer linear programming (“MIP”) matrix, which can then be solved to provide an optimization, based on an annotated entity/relationship data model and a symbolic matrix. The annotated data model identifies one or more outputs of the optimization. The symbolic matrix provides one or more constraints that provide requirements under which the optimization is solved. Outputs of the optimization are represented as variables, inputs of the optimization are represented as constants, and primary keys from the data model are represented as indexes. The constraints are expressed using the variables, constants, and indexes. A MIP matrix is generated from the symbolic matrix, and is then solved by a MIP solver. The output of the MIP solver is used to update a corresponding data structure of the data model.

Abstract: A method and associated device for moving an image displayed on a touchscreen of the device. It is determined that an object previously moving on the touchscreen toward a first outer edge of the touchscreen has traversed the first outer edge in a first direction perpendicular to the first outer edge so as to no longer be touching the touchscreen. The displayed image had moved in the first direction toward the first outer edge in synchronization with the previous movement of the object toward the first outer edge. In response to the object having traversed the first outer edge, one or more motion sensors are activated to monitor the object for continuing movement of the object. The one or more motion sensors ascertain the continuing movement of the object away from the first outer edge, and in response, the displayed image is moved toward the first outer edge.
