The human testes in cases of malignant hematopoietic tumors, especially of leukemia, were histologically examined to characterize the mode of leukemic infiltration in comparison with that of malignant lymphoma. Materials were obtained from 56 autopsy cases, composed of 47 of leukemia, 7 of reticulum cell sarcoma and 2 of lymphosarcoma. Leukemic infiltration was confirmed in 43 (19%) of all leuk...

This paper presents a new automatic framework for extracting and characterizing the dynamic shape of the 3D wetting front and its propagation, based in a sequence of tomographic images acquired as water (moisture) infiltrates in unsaturated soils. To the best of the authors' knowledge, the shape of the 3D wetting front and its propagation and progress over time has not been previously produced ...

Focusing properties of the radially polarized Bessel–Gauss beam with a sine-azimuthal variation wavefront was investigated by the vector diffraction theory. The wavefront distribution is the sine function of the azimuthal angle with one phase parameter that indicates the phase change frequency. Results show that the focal pattern can be altered by the phase parameter, and many novel focal patte...

Reactive melt infiltration is viewed as a promising means of achieving near-net shape manufacturing with quick processing time and at low cost. Since the reactants and products are, in general, of varying density, overall conservation of mass dictates that there is a force related to chemical conversion which can directly influence infiltration behavior. In effect, the driving pressure forces m...

parameter estimation is an important task in the modeling, classification, and detection of radar clutters. radar clutters have stochastic characteristics. therefore, statistical distributions are usually used to describe the features of clutters better. k distribution is one of the most common models utilized to the simulation of clutters. this distribution, which consists of scale and shape p...

A hydrological model based in the cellular automata paradigm, capable to handle extended geographical domains discretized in a large number of cells is presented. The automata simulates the natural surface water flow by tracking local water stocks, book-keeping precipitation, infiltration, evapotranspiration, and intercellular flows. The flow resistance is represented with a relaxation local pa...

*C.W. Rose, Faculty of Environmental Sciences, Griffith University, Queensland 4111, Australia. *Corresponding author: [email protected] ABSTRACT A catena of modeling approaches are briefly reviewed including dynamic stochastic and deterministic approaches. It is shown that a dynamic stochastic description of soil erosion, with appropriate parameter identification, can be identified with...

3D Shape modeling has been a very prominent part of Computer Vision over the past decade. Several shape modeling techniques have been proposed in literature, some are local (distributed parameter) while others are global (lumped parameter) in terms of the parameters required to describe the shape. Hybrid models that combine both ends of this parameter spectrum have been in vogue only recently. ...

The glottal shape parameter Rd provides a onedimensional parameterisation of the Liljencrants-Fant (LF) model which describes the deterministic component of the glottal source. In this paper we first propose to estimate the Rd parameter by means of extending a state-ofthe-art method based on the phase minimization criterion. Then we propose an adaption of the standard Rd parameter regression wh...
