Fluid Catalytic Cracking (FCC) is a major refinery process designed to upgrade heavy and less valuable petroleum products to gasoline and lighter products. The feedstock for the FCC process ranges from light gas oils to heavy hydro-treated resids. The complexity of the feedstock, and the associated analytical chemistry and computational obstacles, helped shape early FCC modeling approaches (2.3...

As one of soft computing optimization tools, Particle Swarm Optimization (PSO) has been applied in many fields such as in handwritten recognition and classification. Associated with the development of PSO algorithm is the data representation to be used as input to the algorithm. One of data representation scheme is Freeman chain code (FCC). As one of traditional scheme in representing data, FCC...

Abstract Family-centred care (FCC) is a key factor in increasing health and related system responsiveness to the needs of children and families; unfortunately, it is an unfamiliar service model in children’s mental health. This critical review of the literature addresses three key questions: What are the concepts, characteristics and principles of FCC in the context of delivering mental health ...

-A new code for Spectral Amplitude Coding Optical Code Division Multiple Access (SAC-OCDMA) is proposed and is called Flexible Cross-correlation (FCC) code. The FCC code possesses various advantages; including easy code construction using Tridiagonal matrix compared to other SAC-OCDMA codes such as MDW, MQC and MFH, shorter code length and the important properties of this code is the flexible c...

The structural properties of Mo and % in the bcc, fcc, and hcp structures are calculated using a fully-self-consistent pseudopotential linear combination of atomic orbitals method. Equilibrium lattice constants, cohesive energies, bulk moduli, differences in structural energies, and Mullikenpopulation analyses are obtained. For both elements, the bcc structure is found to be the most stable whi...

We report a metastable bcc phase that intervenes between a disordered micellar suspension and an fcc crystal in a block copolymer solution. Upon heating, the metastable bcc phase nucleates first, and then transforms over the course of hours to the stable fcc phase. At still higher temperatures, the fcc phase transforms to an equilibrium bcc phase. These results constitute an interesting experim...

Fluidized-bed Catalytic Cracking (FCC) is a process subject to frequent variations in the operating conditions (including feed quality and feed rate). The production objectives usually are the maximization of LPG and gasoline production. This fact makes the FCC converter unit an excellent opportunity for real-time optimization. The present work aims to apply a dynamic optimization in an industr...

In this paper we will present a fuzzy edge detector, FEDGE. It is based on learning fuzzy edges by the method of Fuzzy Categorization and Classification (FCC). A set of images were used as examples for the definition of a fuzzy edge. FCC will try to recognize edges within a new image by collecting evidence from these examples. FEDGE demonstrates that FCC can be used homogeneously from pixel-lev...
