Modeling of magnetizing processes
Article Abstract:
Modeling magnetic materials is challenging because the behavior of magnetic materials is fairly complex. Magnetic materials are nonlinear, anisotropic, and hysteretic and are classified as soft, medium-hard, or hard. There are two general modeling techniques: physical modeling, where the basic processes involved are simulated so the basic magnetizing modes can be described, and phenomenological modeling, where the material's gross behavior is characterized without necessarily including the physical principles involved. Phenomenological modeling is computationally more efficient, but its disadvantages are that it does not give any knowledge about the physical processes involved and does not explain what method to use to tailor the material to improve performance.

Real-time modeling of power networks
Article Abstract:
Tracking changing conditions in a power system with a mathematical model is made possible by the use of large computers in control centers. Assessment and determination of control strategies are done through the use of a real-time model. Constructing the real-time measurement is shown step by step including: determination of network topology, estimation of the network state, and approximate modeling of the unobservable network. Calculation of busload forecast factors, general penalty factors, and checks for observability and bad measurements are also discussed.

Performance analysis of a voice-data multiplexer based on Markov renewal process modeling
Article Abstract:
An integrated voice-data multiplexer is modeled as a Markov renewal process, with the model being used to determine system performance and obtain moments of data queue length at instants of data message departure. The multiplexer has arbitrary length messages and a non-gated service discipline. Behavior of the system's data buffer is analyzed in the continuous-time domain. Data capacity utilization versus data message delay is found to be closer to simulation results than the method of Sriram et al.
