Abstract: A method and system (and/or a total simulation) have at least first and second sub-systems. An interconnection network is determined, which couples and determines the first and the second sub-systems at a coupling. First sub-system information of the first sub-system and second sub-system information of the second sub-system are determined. An execution sequence is selected, by which it is determined, in which sequence relative to each other a first and a second parameter outputs are determined. Furthermore, extrapolation methods are determined, by which first and second parameter inputs are determinable during a macro step size (e.g. between the coupling times). The macro step size prescribes-coupling times, at which an exchange of corresponding first and second input parameters and of the first and the second output parameters between the sub-systems is performed.

Abstract: A computer-implemented method of generating an operation procedure for a simulation of a system, in particular a mechatronic system is disclosed. A source node has at least one source parameter (Ps) and a first simulation system with at least one first simulation node is determined, wherein the first simulation node includes at least one input parameter (Pi) and at least one output parameter (Pa). The first simulation node includes a simulation function for determining the output parameter (Pa) based on the input parameter (Pi) of the first node. When the input parameter (Pi) is available based on the source parameter (Ps), a global operation graph is built describing a link between the source node and the first simulation node for describing an operating procedure of the simulation of the system.

Abstract: A pre-step co-simulation method and device for co-simulation of several subsystems is disclosed, utilizing partial derivatives of replacement subsystems. On this basis, the exact solutions of output variables of the individual subsystems are approximated by evaluation of an Error Differential Equation in order to estimate the future progress of the approximated exact output variables; corresponding input variables are determined by optimization prior to the current co-simulation time increment. The pre-step co-simulation method is realized within a computer-executable program and implemented in a network of computing nodes.

Abstract: So as to make the co-simulation of subsystems of an overall system (1), which are reciprocally coupled by way of coupling variables (y1, y2), real-time capable, a mathematical model (M) of the subsystems (TS1, TS2) which is valid at the current operating point of the overall system (1) is ascertained from input variables (x1, x2) and/or measured variables (w1, w2) of the subsystems (TS1, TS2) based on a method of data-based model identification and, from this model (M), the coupling variables (y1, y2) are extrapolated for a subsequent coupling time step and made available to the subsystems (TS1, TS2).

Abstract: The present invention relates to cyclic polymers and their use in photolithographic applications. The cyclic polymers contain a pendant acid labile functional group and a functional group containing a protected hydroxyl moiety. The polymers are post modified by deprotecting the pendant hydroxyl moiety and reacting the deprotected hydroxyl containing moiety with a coreactant. The post-functionalized polymers find application in chemically amplified photoresist compositions.

Abstract: Addition polymers derived from norbornene-functional monomers are terminated with an olefinic moiety derived from a chain transfer agent selected from a compound having a terminal olefinic double bond between adjacent carbon atoms, excluding styrenes, vinyl ethers, and conjugated dienes and at least one of said carbon atoms has two hydrogen atoms attached thereto. The addition polymers of this invention are prepared from a single or multicomponent catalyst system including a Group VIII metal ion source. The catalyst systems are unique in that they catalyze the insertion of the chain transfer agent exclusively at a terminal end of the polymer chain.
