We present equivalent circuit models of skeletal muscle tissue for the directions parallel and transverse to the fiber. The parallel model is based on a distributed parameter equivalent circuit approach where the tissue between the electrodes is divided into small segments, each of which is represented by an equivalent circuit. Parameters for the equivalent circuits are calculated from the elec...

The vast majority of discrete choice modelling (DCM) applications are now estimated on Stated Preference (SP) data, including but not limited to the field of transport research. In SP data, each respondent is faced with multiple choice situations, and recognising this repeated choice nature of the data is a crucial modelling issue. With the increasing popularity of the Mixed Multinomial Logit (...

a mathematical modelling for more-winding single-phase transformer is presented. the incidence matrix-which gives the informations about the connection of the ends of the windings between the nodes-is multiplied leftside and rightside with the inverse of the inductance matrix of the more winding transformer. the result is a matrix which gives the relationship between nodes potentials and nodes ...

The development of integrated circuits requires powerful numerical simulation programs. Of course, there is no method that treats all the diierent kinds of circuits successfully. The numerical simulation tools provide reliable results only if the circuit model meets the assumptions that guarantee the successful application of the integration software. Because of the large dimension of many circ...

During the application of simulation tools of computational electromagnetics it is sometimes difficult to decide whether the problems can be solved by the computation of electromagnetic fields or circuit simulation tools have to be applied additionally. The paper describes a typical situation in an electromagnetic CAD course, not only for beginners. The modelling and numerical simulation of a s...

In ECAD application areas there is a real need for electrical circuit modelling and analy sis tools at an intermediate level between analogue and state based simulators Numerical tools do not capture the abstractions valued by engineers and logical functional models do not maintain su cient a nities with the electrical properties of a system This paper examines the nature of this problem and th...

This paper presents an overview of the state-of-the-art in black-box modelling with focus on modelling integrated circuits using artificial neural networks. The trade-offs of different model architectures are discussed, including the model building time, training algorithm complexity, and model execution time in circuit simulators. An interchangeable black-box model of a bandgap reference block...
