A 2D+t approach is applied to study the wave pattern generated by high speed slender ships with a sharp stem. This allows approximating the ship motion through a set of equations which are mathematically equivalent to those governing the unsteady 2D

Simple techniques to correct for VCO nonlinearities in short range FMCW radars

Autor: M.P. Tulin, K.D. Ward, Robert A. York, J. Fuchs

Publikováno v: 1996 IEEE MTT-S International Microwave Symposium Digest.

Standard hardware techniques for the linearization of the frequency sweep in FMCW radars are difficult to implement and often offer only moderate improvement in linearity. A simple software-based linearization technique is introduced for short-range

A Lagrangian meshless method for free-surface flows

A distinguishing feature of free-surface flows, and more in general of multi-phase flows, is that interfaces separating media can break and fragment. These circumstances are by no means rare, and are of rather great importance in engineering applicat

Laboratory measurements of the joint dependence of radar frequency and water wavelength on sea-spike returns

Autor: M.P. Tulin, J. Fuchs

Publikováno v: IGARSS '98. Sensing and Managing the Environment. 1998 IEEE International Geoscience and Remote Sensing. Symposium Proceedings. (Cat. No.98CH36174).

Analysis of low grazing angle sea-spikes from breaking waves suggests the presence of a non-Bragg scaling law. The FMCW radar has a frequency chirp of 4-8 GHz. The water wavelength is 1-4 m. The frequency response of the radar cross section peaks in

Laboratory investigations of LGA scattering from wind-generated waves and wave groups

Autor: J. Fuchs, M.P. Tulin, T. Lament-Smith

Publikováno v: IGARSS '98. Sensing and Managing the Environment. 1998 IEEE International Geoscience and Remote Sensing. Symposium Proceedings. (Cat. No.98CH36174).

Scatter characteristics of 50 cm wind-generated waves have been investigated with a C-band radar in a large wind-wave tank. The spectrum of the wind waves was examined in the 2D Fourier domain. The presence of wave groups was made more obvious in the

A study of the steady flow of a rigid-plastic clay beneath a driven wheel

Autor: Gedeon Dagan, M.P. Tulin

Publikováno v: Journal of Terramechanics. 6:9-27

The steady two-dimensional flow benetath a driven rigid cylindrical wheel moving in a soft saturated clay is solved by assuming that the soil behaves like a rigid-plastic material. The general equations of plastic flow are discussed, with ephasis on
