In the present work thermogravimetric techniques were used to study thermal degradation of high-density cork granules. Pyrolysis experiments carried out for four heating ramps (10, 15, 20 and 25 °C.min?1), using nitrogen as carrier gas. From differential (DTG) curves it was seen that mainly occurs from 220 °C 525 main components (suberin, lignin, cellulose, hemicellulose). It also observed temp...

Plastic pyrolysis is widely studied and implemented at lab-scale but rarely modelled numerically. For the sake of designing efficient industrial reactors, modelling plastic process particle scale could be a prerequisite. Therefore, aim this work to model whole process, on scale, for polypropylene (PP) high density polyethylene (HDPE) inside thermogravimetric analyzer coupled with differential s...

This paper considers an important model of boundary value problem with a condition at infinity namely combined free and forced convection over a plane of arbitrary shape embedded in a fluid-saturated porous medium; this model admits dual solutions, and uses a technique, which is to some extent modification of homotopy analysis method (HAM), in order to obtain dual solutions analytically with hi...

We propose a region-based method for model-free object tracking. In our method the object information of temporal motion and spatial luminance are fully utilized. We first compute dominant motion of the tracked object. Using this result we warp the object template to generate a prediction template. Static segmentation is incorporated to modify this prediction, where the warping error of each wa...

It is well-known that conventional control theories are widely suited for applications where the processes can be reasonably described in advance. However, when the plant’s dynamics are hard to characterize precisely or are subject to environmental uncertainties, one may encounter difficulties in applying the conventional controller design methodologies. Despite the difficulty in achieving high...

In gene expression data analysis, discriminator genes are importantly informative genes for further research. Recently, a great deal of research has focused on the challenging task of identifying these informative genes from microarray data. However, the sizes of sample classes in microarray data are often unbalanced. The unbalance of samples has not been explicitly and correctly considered by ...

Moving Particle Semi-implicit (MPS) which is a meshless and full Lagrangian method is employed to simulate nonlinear hydrodynamic behavior in a wide variety of engineering application including free surface water waves. In the present study, a numerical particle-based model is developed by the authors using MPS method to simulate different wave problems in the coastal waters. In this model flui...
