Particle breakability assessment using an Aero S disperser

assessment of the efficiency of s.p.g.c refineries using network dea

data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

An approach to Improve Particle Swarm Optimization Algorithm Using CUDA

The time consumption in solving computationally heavy problems has always been a concern for computer programmers. Due to simplicity of its implementation, the PSO (Particle Swarm Optimization) is a suitable meta-heuristic algorithm for solving computationally heavy problems. However, despite the simplicity, the algorithm is inefficient for solving real computationally heavy problems but the pr...

A method for grindability testing using the Scirocco disperser.

In the early stages of development of a new Active Pharmaceutical Ingredient (API), insufficient material quantity is available for addressing processing issues, and it is highly desirable to be able to assess processability issues using the smallest possible powder sample quantity. A good example is milling of new active pharmaceutical ingredients. For particle breakage that is sensitive to st...

Toward aero-acoustical analysis of the sibilant /s/: an oral cavity modeling

We analyzed the sibilant /s/, an unvoiced consonant, by considering turbulence and vortex sound. A segmentation technique for four dimensional magnetic resonance imaging (4D-MRI) of data considering the movements of the oral cavity is proposed. The conventional Snakes can not segment the quick deformation of the tip of the tongue in 4D-MRI images. To segment the quick motion, optical flow of 4D...
