In this paper, fuzzy logic control of a fluid catalytic cracking unit (FCCU) is proposed. Fluid catalytic cracking (FCC) process is a unit that converts heavy distillates like gas oil or residues to gasoline and middle distillates using cracking catalyst. About 45% of worldwide gasoline production comes from FCC processes and its ancillary units. Since a typical FCC unit can process a large amo...

Fe,,,Ni, with xs30 at.%, known as anti-Invar alloys, undergo mprtensitic transformations. Total energy calculations have shown that these alloys incorporate a strongly fluctuating magnetic moment in the fcc state. In order to undeixtand the relationship between the moment fluctuations and the martensitic transformation, we have investigated the magnetic moment in the paramagnetic fcc state of t...

Marinobacter sp. strain CAB was cultivated with or without porous glass beads as solid support. Two substrates were used: the hydrophilic sodium lactate and a hydrophobic C(18)-isoprenoid ketone (6,10,14-trimethylpentadecan-2-one (TMP)). The substrate adsorption onto the beads was measured. Bacterial adhesion was determined by a direct count technique and amounted to 70% of total cells. In the ...

Family-Centered Care (FCC) is a way to provide health care that recognizes the importance of family for a hospitalized child. According to it, it is essential to involve families in their children’s recovery plan [1]. FCC was born in the Fifties of 20th century as a reaction to the leading idea in Pediatric care that emphasized physical care, technical abilities and emotional detachment and con...

In July 2000 the FCC issued the rules to govern the upcoming 700MHz auction. The rules are a departure from the auction architectures previously used by the FCC. Rather than all bidding only on individual licenses, the auction participants will be able to bid on combinations or packages of licenses. Several combinatorial auction processes exist in the literature and testing demonstrates that su...

For generic 3D sampling, the Body Centered Cubic (BCC) lattice and the Face Centered Cubic (FCC) lattice are significantly superior to the traditionally popular Cartesian Cubic (CC) lattice. Motivated by the goal of high visual fidelity in the visualization community, this thesis investigates the relative perceptual merits of high quality reconstruction filters for CC, BCC, and FCC sampled data...

High-accuracy lattice sums have been evaluated for the Lennard-Jones 12-6 pair potential, without cutoffs, in the close-packed fcc and hcp lattices. The results confirm the small relative stability of hcp at low pressure, and locate precisely the first-order phase transition at zero temperature to the fcc structure. The reduced pressure p / at this transition is approximately 878.476 . . . , wi...

We use a hybrid Monte Carlo algorithm to simulate the shaking of spheres at different vibrational amplitudes and find that spontaneous crystallization occurs in specific dynamical regimes. Several crystallizing transitions are typically observed, leading to end states which can be fully or partially ordered, depending on the shaking amplitude, which we investigate using metrics of global and lo...

AIM The aim of this study is to explore the history of family-centered care (FCC). BACKGROUND FCC was developed after Word War II, when nursing, then deeply paternalistic, had become asynchronous with changing social expectations for the care of hospitalized children. METHODS This is a historical review of literature reflecting development of pediatric models of care using publications of c...

Introduction Net neutrality—the notion that all Internet traffic, regardless of its source or type, must be treated the same by Internet Service Providers (ISPs)—is back on the nation’s political radar. The catalyst was the D.C. Court of Appeals’ decision last January in Verizon v. FCC, which overturned the Federal Communications Commission’s (FCC) “Open Internet Order.” The essence of the Cour...
