Volumetric visualization of medical data is a specific task, as doctors and radiology technicians are not well trained in the field of computer graphics; therefore, algorithms for visualization of medical data must be as intuitive as possible, so that visualization tools employing them would be helpful in medical environment. Visualization of volumetric data acquired by medical imaging could no...

Batch studies of acid dyes sorption by orange peel were carried out to identify the main rate controlling steps in the overall uptake mechanism, using a single external mass transfer diffusion model and intraparticle mass transfer diffusion model. Certain classical parameters influencing dyes sorption mechanisms namely: initial acid dyes concentration and dye type were investigated. The approac...

The gas–liquid hydrodynamics and mass transfer were studied in a concentric tube internal jet-loop airlift reactor with conical bottom. Comparing standard design, the gas separator was equipped an adjustable deflector placed above riser. effect of riser superficial velocity uSGR on total holdup ?GT, homogenization time tH, overall volumetric liquid-phase coefficient kLa investigated laboratory ...

BACKGROUND AND PURPOSE In the developing brain, myelination occurs in an orderly and predetermined sequence. The aim of this study was to determine whether such changes can be tracked using volumetric magnetization transfer imaging. METHODS Three-dimensional magnetization transfer imaging was performed in 50 children (age range, 0.6-190 months) with no evidence of developmental delay or struc...

We introduce a transfer-function-guided 3D blockbased saliency-aware compression scheme for volumetric data that is both contentand spatially-scalable. Salient 3D volumetric blocks are identified and weighted with the help of a transfer function which is used to render the data. We describe our method in the form of a framework for processing, progressive transmission, and visualization of volu...

The unsteady response of nozzles with steady heat transfer forced by acoustic and/or entropy waves is modelled. approach based on the quasi-one-dimensional linearised Euler equations. equations are cast in terms three variables, namely dimensionless mass, stagnation temperature and fluctuations, which invariants system at zero frequency no transfer. resulting first-order differential then solve...

Due to the undesirable environmental consequences ofR12, there is a great challenge to find a suitable substitute for Rl2. A new refrigerant blend Rl34a!R218/R600a (88'Yoi9'Yol 3%) called JSCEON 49 has been developed as a long term, zero ozone depletion-potential replacement for Rl2. A computer program was written to calculate the cycle characteristics, such as cooling capacity, coefficient of ...

Direct volume rendering techniques have been successfully applied to visualizing volumetric datasets across many application domains. Due to the sensitivity of transfer functions and the complexity of fine-tuning transfer functions, direct volume rendering is still not widely used in practice. For fast volumetric data exploration, we propose Importance-Based Accumulated Transparency Modulation ...
