Abstract: A system and method for identifying characteristics of a physical system applies substantially identical drive ensembles to the physical system and obtains corresponding responses from the physical system. A repeatable bandwidth of the physical system is estimated as a function of the applied drive ensembles and the corresponding obtained responses. Instructions can be provided on a computer readable medium to perform the method.

Abstract: Provide an electronic-business-to-electronic-business portal that organizes the access to extended business applications. A method allows end users to access a server using standard Web browsers, and then view their own customized menu of applications. Enhanced security and administrative tools allow this portal to be shared throughout enterprises and across supply chains, providing secure access to collaborative applications by business partners and suppliers. Access to specific applications is granted to authorized users and teams, within and outside of a company. Real-time, on-line registration of users allows for rapid changes in teams and projects. Users can be added, deleted, or have access levels altered to reflect changes in the makeup of teams. Provide a common infrastructure for application administration, security management, and directory use, which can help reduce information technology (IT) costs and speed solution deployment.

Abstract: A unique transistor model and methods for analyzing the model are disclosed. The transistor model of the present invention is simple and requires specification of a minimal number of parameters to simulate transistor operation. Three analysis methods are disclosed, each having unique circumstances for application A first method is premised on sampling all waveforms in the circuit and determining the operating point of the transistor. The first method assumes an input of an arbitrary periodic waveform. The first method is very flexible and may be used with a wide range of models other than the disclosed model. A second and a third method are premised on input and output waveform clipping. The second method assumes a single tone input into the transistor. The third method is a combination of features from the first and second methods. The third method is computationally efficient and assumes an arbitrary periodic input waveform.

Abstract: A digital television satellite or cable system broadcasts to receiver/decoders which also receive control information (control programs, i.e. applications) to allow such tasks as reviewing television programme listings, setting up home banking interactions, and answering quiz questions connected with programmes being transmitted. The invention provides a method of developing such control programs on a workstation 4013. The workstation is coupled to a receiver/decoder-type unit 2021 which substantially duplicates the receiver/decoder with a television set 2023 coupled thereto. Control programs are developed including control statements responsive to signals from the workstation and test statements which return signals to the workstation. The program is passed to the receiver/decoder-type unit, and a synthetic broadcast digital television signal is generated (at 4045) and fed to the receiver/decoder-type unit.

Abstract: A computer based, iterative process for generating chemical entities with defined physical, chemical and/or bioactive properties. During each iteration of the process, (1) a directed diversity chemical library is robotically generated in accordance with robotic synthesis instructions; (2) the compounds in the directed diversity chemical library are analyzed to identify compounds with the desired properties; (3) structure-property data are used to select compounds to be synthesized in the next iteration; and (4) new robotic synthesis instructions are automatically generated to control the synthesis of the directed diversity chemical library for the next iteration.
