“…Values of the discrete current sources are determined by satisfying the boundary conditions at a selected number of contour points. Once the values and positions of simulation current sources are known, the potential and field distribution anywhere in the region can be computed easily [10].…”

-Soil resistivity measurements are considered very important task for grounding system design and analysis. The metallic structures in vicinity of grounding system have significantly effect on the performance of grounding system. Ideally, soil resistivity measurements should be made in the absence of buried metallic conductors or structures. Soil resistivity measurements may have to be made in the presence of the grounding system, if the performance of an existing grounding system is necessary to review or evaluate. Soil resistivity measurements made with the Wenner are carried out with and without a nearby grounding grid, in Taif (KSA) soil. Comparisons are made between the results, with and without the grounding grid, to show the effect due to the presence of the grid. The influence of different metallic structures and modified measurement profiles which reduce the influence of metallic structures will be discussed. A mathematical model for computing the soil resistivity in case of multilayer soil will be investigated. A new technique is proposed to calculate the grounding resistance of multilayer soil by a numerical method as current simulation method.

Many acoustical simulation methods have been studied to investigate acoustical phenomena. Modeling of the directivity pattern of a sound source is also important for obtaining realistic simulation results. However, there has been little research on this. Although there has been research on sound source identification, the results might not be in a suitable form for numerical simulation. In this paper, a method for modeling a sound source from measured data is proposed. It utilizes the sum of monopoles as the physical model, and the modeling is achieved by estimating the model parameters. The estimation method is formulated as a convex optimization problem by assuming the smoothness of a solution and the sparseness of parameters. Moreover, an algorithm based on the alternating direction method of multipliers (ADMM) for solving the problem is derived. The validity of the method is evaluated using simulated data, and the modeling result for an actual loudspeaker is shown.

-The performance of transmission lines and its shielding design during a lightning phenomenon are quite essential in the maintenance of a reliable power supply to consumers. The leader progression model, as an advanced approach, has been recently developed to calculate the shielding failure rate (SFR) of transmission lines using geometrical data and physical behavior of upward and downward lightning leaders. However, such method is quite time consuming. In the present paper, an effective method that utilizes artificial neural networks (ANNs) to create a metamodel for calculating the SFR of a transmission line based on shielding angle and height is introduced. The results of investigations on a real case study reveal that, through proper selection of an ANN structure and good training, the ANN prediction is very close to the result of the detailed simulation, whereas the Processing time is by far lower than that of the detailed model.
