Computational Methods of Ultrasound Wave Propagation in Healing Long Bones D. I. Fotiadis1 Summary Quantitative ultrasound has attracted significant interest in the evaluation of bone fracture healing. Animal and clinical studies have demonstrated that the propagation velocity across fractured bones can be used as an indicator of healing. Researchers have recently employed computational methods...

This paper discusses several current attempts to use acoustic and electromagnetic wave propagation for modeling physical phenomena and the role that wavelet analysis is playing in these eeorts. The rst problem involves recent application of wavelets to computational uid dynamics. The second problem involves geophysical modeling of the ocean oor, using acoustic waves, and wavelets have recently ...

 In recent years the application of computer algebra systems devoted to Mathematics and Physics have become very popular both in instruction and scientific research. In this paper some issues arising in solving and modelling mathematical and physical problems in wave propagation will be discussed. In particular, computer algebra systems make easy to provide at the same time a large amount of d...

In cancellous bone, longitudinal waves often separate into fast and slow waves depending on the alignment of bone trabeculae in the propagation path [1]. This interesting phenomenon becomes an effective tool for the diagnosis of osteoporosis because wave propagation behavior depends on the bone structure [2]. Nagatani et al. pointed that fast wave requires certain propagation distance for stead...

it is well-known that dam-reservoir interaction has significant effects on the response of dams to the earthquakes. this phenomenon should be considered more exactly in the seismic design of dams with a rational and reliable dynamic analysis method. in this research, seismic analysis of the dam-reservoir is studied as a wave propagation problem by using legendre spectral element method (sem). t...
