| Abstrak | : | Ultrasonic scattering in inhomogeneous fluid media is examined. Of particular interest are those media having a compressibility that varies on a continuum of spatial scales. It is shown that the internal features of such media can be extracted by an analysis of the forward scattered field. The angular distribution of scattered pressure intensity is found to vary with frequency and compressibility contrast. The scattered field data can be rendered stationary to such variations by an application of a similarity transformation. Examples are given for cases where the spatial variation in the compressibility of the media obeys either a power law or exponential correlation function. When these similarity transformations are applied, an estimate of the characteristic radius of the scatterers and the fractal dimension of the medium can be directly obtained.<> |

| Abstrak | : | The application of fractal random process models and their related scaling parameters as features in the analysis and segmentation of clutter in high-resolution, polarimetric synthetic aperture radar (SAR) imagery is demonstrated. Specifically, the fractal dimension of natural clutter sources, such as grass and trees, is computed and used as a texture feature for a Bayesian classifier. The SAR shadows are segmented in a separate manner using the original backscatter power as a discriminant. The proposed segmentation process yields a three-class segmentation map for the scenes considered in this study (with three clutter types: shadows, trees, and grass). The difficulty of computing texture metrics in high-speckle SAR imagery is addressed. In particular, a two-step preprocessing approach consisting of polarimetric minimum speckle filtering followed by noncoherent spatial averaging is used. The relevance of the resulting segmentation maps to constant-false-alarm-rate (CFAR) radar target detection techniques is discussed.<> |

| Abstrak | : | The consequences of the parameterization of the fractal set on the electrodynamics of this set are analyzed. The relevance of scaling properties to electrochemical, dielectric, and magnetic relaxations is considered with a special emphasis on the use of noninteger derivative operators in electromagnetism and superconductivity. In electromagnetism, the above analysis includes a brief overview of the main results already obtained, focusing especially on the introduction of dissipative terms in the equation of propagation and on the generalized form of the uncertainty principle in fractal media. The new Laplacian and d'Alembertian operators are evoked as well as the scale relativity on which this new analysis is founded. For superconductivity, the analysis introduces a geometrical interpretation founded on frustration acting not only on topology but on the metric of the space-time in a particular type of fractal geometry. Although this point of view may appear as a breakthrough in the theory of superconductors, the model offers some relations with the theory of fractional statistics and the theory of Anyons.<> |

| Abstrak | : | The emergent, collective properties of computer interconnections are shown to be characterized by a noninteger dimension D/sub i/, which is, in general, different from the system's Euclidean dimension. This dimension characterizes the properties of a fractal support, or substrate, on which interconnections are placed to provide communication throughout the system. The interconnection support also acts as a host for a multifractal spectrum of interconnection distribution processes which characterize the change in connectivity in moving from the backplane to the transistor level. The properties of fractal systems are investigated by attempting to minimize their total wire length using a simulated annealing algorithm. Systems whose interconnection dimension is approximately equal to their Euclidean dimension are shown to possess minimum wire length arrangements. These results are then interpreted in terms of a geometrical temperature T/sub i/=1/D/sub i/. This analysis indicates that the system passes through a phase transition at T/sub i/ approximately=1/2 and that attainable system temperatures are bounded by 1/3> |
