Numerical Method of Computing Impedances in Shielded and Unshielded Three-phase Rectangular Busbar Systems

In this paper, a new numerical method of calculating rectangular busbar impedance is proposed. This method is based on integral equation method and partial inductance theory. In particular, impedances of shielded and unshielded three-phase systems with rectangular phase and neutral busbars, conductive enclosure, and use of the method are described. Results for resistances and reactances for the...

Shielded and unshielded geometries in the search for orphan sources.

A car-borne NaI(Tl) spectrometric system was used together with a 137Cs source to obtain realistic data in the search for unshielded and semi-shielded orphan sources. The potassium-stripped counts (PSC) method was used to estimate the influence by the shielding on the detection ability. A reduction of about 5% in the critical distance was obtained for the semi-shielded source. A curve fitting m...

Three-dimensional numerical modeling of score hole in rectangular side weir with finite volume method

Local scouring in the downstream of hydraulic structures is one of the important issues in river and hydraulic engineering, which involves a lot of costs every year, so the prediction of the rate of scour is important in hydraulic design. Side weirs are the most important of hydraulic structures that are used in passing flow. This study investigate the scouring due to falling jet from side weir...

Three-dimensional rectangular vocal-tract model with asymmetric wall impedances

A method to compute the acoustic characteristics of a simplified three-dimensional vocal-tract model with asymmetric wall impedances is presented. The acoustic field is represented in terms of both plane waves and higher-order modes in tubes. This model is constructed using a connected structure of rectangular acoustic tubes, and can parametrically represent acoustic characteristics in higher f...

Numerical method for calculating input impedances of the oboe

The purpose of this study was to investigate a numerical method for obtaining input impedances of doublereed instruments--the oboe in particular. To this end, the physical dimensions of an oboe were used to compute its input impedance as a function of frequency for several different fingerings. The numerically computed input impendances of the oboe were compared to experimentally measured curve...
