In this paper, the Morphological Skeleton Interpolation (MSI) algorithm is presented. It is an eecient shape-based interpolation method used for interpolating slices between successive slices of a 3-D object. It is based on the well known mathematical morphology procedure of morphological skeletonization, that is used as a representation of an object. The proposed morphological skeleton matchin...

segmentation and three‑dimensional (3d) visualization of teeth in dental computerized tomography (ct) images are of dentists’ requirements for both abnormalities diagnosis and the treatments such as dental implant and orthodontic planning. on the other hand, dental ct image segmentation is a difficult process because of the specific characteristics of the tooth’s structure. this paper presents ...

A method for the long-term storage of liver slices by cryopreservation was developed. The viability of liver slices was determined by analyzing the leakage of alanine aminotransferase, urea production, and the metabolism of testosterone. Rat liver slices were found to be optimally cryopreserved by exposure to for 30 min to 12% dimethylsulphoxide (v/v) on ice before freezing. Subsequent direct i...

Currently the most popular method to evolve black-hole binaries is the “moving puncture” method. It has recently been shown that when puncture initial data for a Schwarzschild black hole are evolved using this method, the numerical slices quickly lose contact with the second asymptotically flat end, and end instead on a cylinder of finite Schwarzschild coordinate radius. These slices are statio...

the analytic signal method is a semiautomatic method for estimating the location of causative bodies in magnetic and gravity methods. the application of analytic signal for interpretation of two dimensional (2d) structures was introduced by nabighian (1972). the analytic signal is defined as a complex function in which the real and imaginary parts are a pair of hilbert transforms. in other word...

Mixtures of rigid sand particles and soft rubber (rubber chips) are prepared submitted to vertical taps in a confined cell investigate their propensity segregate. The mixture evolution is characterized by means image analysis slices obtained gelification technique. We show that, case equally sized particles, the tend migrate towards bottom system. Yet, segregation not complete reduced when frac...

spectral decomposition of time series has a significant role in seismic data processing and interpretation. since the earth acts as a low-pass filter, it changes frequency content of passing seismic waves. conventional representing methods of signals in time domain and frequency domain cannot show time and frequency information simultaneously. time-frequency transforms upgraded spectral decompo...

1. Precision-cut liver slices represent a suitable and convenient in vitro preparation for studying metabolism and toxicity mechanisms of drugs and toxic chemicals. Particularly in the case of human liver slices, cryopreservation would enable more efficient utilization of this scarce and irregularly available tissue. 2. Liver slices from consecutive human livers were cryopreserved using a metho...
