This study deals with wave-induced unsteady pressure on a ship moving constant forward speed in regular head waves. Two different numerical methods are applied to solve wave–ship interaction problems: Rankine panel method which adopts velocity potential, and Cartesian-grid solves the momentum mass conservation equations under assumption of inviscid incompressible fluids. Before comparing l1ocal...

Abstract Radar is a system that uses radio waves to detect any objects pass through the range of its system. The radar must have two main components which are transmitter and receiver. passive forward scattering being used target’s speed size. This cell tower Long-Term Evolution (LTE) as will illuminate moving targets receiver can be remotely placed scattered radiation target. detection target ...

In a simple, forward looking linear stochastic model we investigate the impact of heterogeneity in expectations formation on the speed of convergence of the learning process of agents towards equilibrium. We …nd that even when heterogeneity does not a¤ect learnability in term of its asymptotic outcome, it can still have an important impact on the learnability of an equilibrium in terms of the s...

In this study, we investigated the effect of viewpoint density and speed of motion on perceived smoothness of viewpoint transitions. The effect of viewpoint density was examined for two types of viewer motion: forward and lateral motion. In both cases, we found that perceived smoothness varies with viewpoint density. We also found the number of viewpoints required to maintain a certain level of...

The coupling and spatial variation of range azimuth parameters is the biggest challenge for bistatic forward-looking SAR (BFSAR) imaging. In contrast with monostatic translational invariant (TI-BSAR), cell migration (RCM), Doppler high-speed (HS-BFSAR) have two-dimensional characteristics, which makes it difficult to obtain images satisfactory global focusing. Firstly, based on configuration sp...
