In this work, the triple convolution of Daubechies wavelet is used to solve the three dimensional (3D) microscale Dual Phase Lag (DPL) problem. Also, numerical solution of 3D time-dependent initial-boundary value problems of a microscopic heat equation is presented. To generate a 3D wavelet we used the triple convolution of a one dimensional wavelet. Using convolution we get a scaling function ...

Objective: Detection and evaluation of adrenal glands are complex problems in conventional ultrasonography in dogs. Using three-dimensional (3D) ultrasonography (US) in adrenal gland volume evaluation can add new potential for further adrenal studies. Design: Descriptive study Animals: a total of 10 mix breed dogs Procedures: The dogs underwent two dimensional (2D) and 3D US of the adrenal g...

background: the accuracy and reproducibility of measurements in a locally made three dimensional (3d) simulator was assessed and compared with manual caliper measurements. materials and methods: a total of 20 casts were scanned by our laser scanner. software capabilities included dimensional measurements, transformation and rotation of the cast as a whole, separation and rotation of each tooth ...

background: this study describes the possibility of implementing three-dimensional printing technology to create a precise construction of a planned bolus, based on computed tomography information stored in the digital imaging and communications in medicine (dicom) format file. materials and methods:  to create the bolus with a 3d printer, we converted data in the dicom format to the stereolith...

in this paper the problem of 3d scene and object classification from depth data is addressed. in contrast to high-dimensional feature-based representation, the depth data is described in a low dimensional space. in order to remedy the curse of dimensionality problem, the depth data is described by a sparse model over a learned dictionary. exploiting the algorithmic information theory, a new def...

Background The aim of this study was the ex vivo expansion of Umbilical Cord Blood hematopoietic stem cells on biocompatible nanofiber scaffolds. Materials and Methods CD133+ hematopoietic stem cells were separated from umbilical cord blood using MidiMacs (positive selection) system by means of monocolonal antibody CD133 (microbeads) subsequently, flowcytometry method was done to asses...

backgrounds: evidence is accumulating to support disruption of tissue architecture as a powerful event in tumor formation. for the past four decades, intensive cancer research with the premise of “cancer as a cell based-disease” focused on finding oncogenes or tumor suppressor genes. however, the role of the tissue architecture was neglected. three dimensional (3d) cell cultures which can recap...

The three-dimensional (3D) integrated circuit technology developed by MIT Lincoln Laboratory allows circuit structure that forms on several silicon-on-insulator (SOI) substrates to be integrated into a 3D integrated circuit. This 3D technology gives the possibility of better thermal and noise management, more compact design, and so on. However, circuit design in the 3D technology has not been f...

Developing realistic three-dimensional stimuli is an integral part of research on visual perception and cognition, including implicit and explicit forms of visual memory, symmetry perception, object recognition, and perceptual categorization. This is particularly important for object representation research because many theories that were developed with simplified two-dimensional stimuli turned...
