This paper presents new features recently added to a general-purpose surge simulation code based on the FDTD (Finite Difference Time Domain) method. The added features include various-shape conductor models, lumped-parameter circuit-element models, a lightning-channel model, and an integrated analysis environment (IAE). For precisely modeling the shapes of various conductors, the following cond...

This article rethinks the basic assumptions often used in analytically modeling parasitic capacitance inductors. These are classified two commonly-used physics-based analysis methods: lumped capacitor network method and energy conservation method. The lumped-capacitor is not proper solution for calculating equivalent inductors at first resonant frequency, but rather represents above last freque...

Structural damage to r.c. buildings located in a near-fault area has been observed during strong ground motions, with long-duration horizontal pulses and high values of the ratio between the peak value of the vertical acceleration and the analogous value of the horizontal acceleration. The design provisions of current seismic codes are generally not very accurate for assessing the structural ef...

Predicting the Seismic Behavior of the Dywidag Ductile Connector (DDC) Precast Concrete System Elizabeth Mary Kenyon Structural engineering is heavily dependent on the use of computers. When creating a building model using structural analysis software, it is required that the designer have an understanding of the system behavior and the modeling program capabilities. Some engineers in the South...

In the post-genomic era, Genome-scale metabolic networks (GEMs) have emerged as invaluable tools to understand metabolic capabilities of organisms. Different parts of these metabolic networks are defined as subsystems/pathways, which are sets of functional roles to implement a specific biological process or structural complex, such as glycolysis and TCA cycle. Subsystem/pathway definition is al...

In recent years, magnetic resonance imaging (MRI) systems that operate up to under 3 T are being used in clinical practice in Japan. In order to achieve the requirements of higher image quality and shorter imaging times, devices that utilize high magnetic fields (> 3 T) and high power electromagnetic (EM) wave pulses have been developed. The rise of the static magnetic field is proportional to ...
