A component interface creator automatically generates a component interface based on the information gathered by the parsing mechanism.

Abstract: A system for modeling, simulating and analyzing chemical and biochemical reactions includes a modeling environment for constructing a model of a chemical or biochemical system comprising a plurality of chemical reactions. Each chemical reaction has a probability distribution associated therewith based on the kinetics of the particular chemical reaction. The probability distribution may be set by a user, determined automatically, or experimentally determined. The system also includes a simulation engine accepting as input said constructed model of the chemical or biochemical system and generating as output an expected result. The simulation engine calculates a reaction time for each chemical reaction based on the probability distribution associated with the particular chemical reaction. An analysis environment communicates with the simulation engine and displays the expected result.

Abstract: A mechanism in a block diagram environment allows the modeling of an execution behavior of a block in a block diagram, where a user selects the execution behavior from a plurality of functions related to the block diagram and where the execution behavior of the block is performed when at least one model variable associated with the block satisfies a user-specified condition is disclosed. States and other internal data in the designated block are initialized upon the satisfaction of the user-specified condition. The illustrative embodiment of the present invention also allows the internal data to be reset upon the ending of the event, such as the modeled introduction or withdrawal of power. The execution behavior may be suspended and resumed multiple times during the simulation in response to multiple occurrences of the specified event. The present invention also allows for selected data to be exempt from the reset process so that the selected data is non-volatile.

Abstract: A mechanism for transparently identifying and retrieving an instrument driver to an application development environment that is associated with a user-selected instrument is disclosed. Following a user selection of an instrument through a user interface generated by the application development environment, an instrument driver associated with the selected instrument is programmatically identified. If the required instrument driver for the selected instrument is missing from the application development environment, the illustrative embodiment of the present invention retrieves the instrument driver from a remote location and installs the instrument driver in the application development environment without the involvement of the user. In one aspect of the illustrative embodiment of the present invention, metadata associated with the instrument driver is examined before any installation of the instrument driver takes place.

Abstract: A method and apparatus, including a computer program apparatus, implementing techniques for generating a report from a technical computing environment provided by a mathematical computer program. A report generator defines a set of reporting components that can be assembled to form a report template and processes the reporting components of the report template in order to extract data from the mathematical computing environment and generate the report. The report generator includes a user interface by which a designer can hierarchically assemble the reporting elements, which are defined according to an object-oriented programming language. The report generator bi-directionally communicates with the mathematical computing environment such that the report generator can evaluate expressions defined within the mathematical computing environment, change initial conditions and parameters of a mathematical model, and issue commands to advance the simulation time of the model.

Abstract: A graphical block that defines the functionality of a lookup table and can be used in a block diagram model to capture time-varying characteristics of a system's behavior in the lookup table is presented. The block uses input and output data of the system to dynamically create and update the contents of the underlying lookup table over time. More specifically, the block utilizes an adaptation process that uses the system (or plant) output data to recompute the table values. The adaptation process is implemented as a statistical and signal processing algorithm, such as Recursive Sample Means (RSM), Least Mean Squares (LMS) and Recursive Least-Squares (RLS). The adaptation can be cell-based or point based.

Abstract: A mechanism for constructing a software-based instrument panel or front panel in which the components correspond directly with sections of code in a textual language program is disclosed. The textual language program relates to how the panel updates and operates in a continuous fashion. Icons representing panel components are selected from a component library window displayed to a user. The act of dragging the icon representing the components into the Graphical Panel Layout Window automatically causes the corresponding code to be added to the textual language program and displayed to the user in a Program Dialog Window. The present invention displays both a Graphical Panel Layout Window showing the components in the instrument panel and a Program Dialog Window showing the lines of code for the textual language program controlling the operation of the components in the instrument panel. A library containing I/O dialog devices is also presented and displayed to a user.

Abstract: An RMI (Remote Method Invocation) service framework that enables a non-Java application to be managed by an RMI activation system daemon is disclosed. The present invention enables the non-Java application to communicate with other Java applications that make use of RMI following a registration process. Additionally, because the non-Java application is managed by the RMI activation system daemon, the non-Java application displays a high degree of persistence and/or reliability ordinarily associated with RMI services. As a result, non-Java applications may be used to perform distributed and parallel computing tasks in a more efficient manner than is possible with conventional methods.

Abstract: A method and apparatus, including a computer program apparatus, which facilitate invoking methods of objects defined within an object-oriented environment from an array-based technical computing environment often used in conventional mathematical tools. When a method is invoked from the computing environment, the techniques automatically compare the array input parameters with data-types accepted by methods defined within the object-oriented environment. Based on this comparison, the invention selects a method that best accepts the input arrays. The invention, therefore, allows a user to easily invoke methods from external objects, such as Java objects, directly from the technical computing environment of the mathematical tool.

Abstract: The automatic generation of a real-time scheduler for scheduling the execution of tasks on a real-time system is disclosed. The scheduler may allow task overruns in the execution of the tasks on the real-time system. The task overruns may occur when the execution of a task for a current sample hit is not completed before a next sample hit. When the task overruns occur, the scheduler may delay the execution of the task for the next sample hit until the execution of the task for the current sample hit is completed. The execution of the task for the next sample hit is performed after the execution of the task for the current sample hit is completed. The present invention may enable users to input information relating to the behavior in real-time execution of the graphical programs or models. The present invention may simulate the graphical programs or models using the information on the behavior of the graphical programs or models executed in the real-time execution.
