The fast development of new products, process technologies and production methods has made the decision making in process design and synthesis a complicated task. Combination of all feasible process pathways and solutions creates a huge super structure. Thus, to determine the optimum solution and flexible alternative solution is a big challenge for Process Network Synthesis (PNS). Process graph (P-graph) approach has been extended gradually to provide a friendly and fast optimum result for PNS problem. This paper overviews the application of P-graph in new PNS areas in the aspect of synthesis, optimisation, planning and management. The paper demonstrates the extension of P-graph via several case studies such as effective supply chain systems, carbon emission reduction systems and cleaner production process synthesis. The paper also highlights the advantages of P-graph in process network synthesis. © 2013 Elsevier Ltd. All rights reserved. Source

We study the Casimir interaction between a sphere and a cylinder both subjected to Dirichlet, Neumann, or perfectly conducting boundary conditions. Generalizing the operator approach developed by Wittman, we compute the scalar and vector translation matrices between a sphere and a cylinder, and thus write down explicitly the exact TGTG formula for the Casimir interaction energy. In the scalar case, the formula shows manifestly that the Casimir interaction force is attractive at all separations. The large separation leading term of the Casimir interaction energy is computed directly from the exact formula. It is of order ∼âcR1/[L2lnâ¡(L/R2)], ∼âcR13R22/L6, and ∼âcR13/[L4lnâ¡(L/R 2)], respectively, for Dirichlet, Neumann, and perfectly conducting boundary conditions, where R1 and R2 are, respectively, the radii of the sphere and the cylinder, and L is the distance between their centers. © 2013 American Physical Society.

We derive analytically the asymptotic behavior of the Casimir interaction between a sphere and a plate when the distance between them, d, is much smaller than the radius of the sphere, R. The leading-order and next-to-leading-order terms are derived from the exact formula for the Casimir interaction energy. They are found to depend nontrivially on the dielectric functions of the objects. As expected, the leading-order term coincides with that derived using the proximity force approximation. Numerical results are presented when the dielectric functions are given by the plasma model or the Drude model, with the plasma frequency (for plasma and Drude models) and relaxation frequency (for Drude model) given by the conventional values used for gold metal. It is found that if plasma model is used instead of the Drude model, the error in the sum of the first two leading terms is at most 2%, while the error in θ1, the ratio of the next-to-leading-order term divided by d/R to the leading-order term, can go up to 4.5%. © 2013 American Physical Society.

We consider the interaction between a spherical plasma sheet and a planar plasma sheet due to the vacuum fluctuations of electromagnetic fields. We derive the TGTG formula for the Casimir interaction energy and study its asymptotic behaviors. In the small separation regime, we confirm the proximity force approximation and calculate the first correction beyond the proximity force approximation. This study has potential application to model Casimir interaction between objects made of materials that can be modeled by plasma sheets such as graphene sheets. © 2014 American Physical Society.

We consider the Casimir interaction between two spheres corresponding to massless Dirac fields with MIT-bag boundary conditions. Using operator approach, we derive the TGTG formula for the Casimir interaction energy between the two spheres. A byproduct is the explicit formula for the translation matrix that relates the fermionic spherical waves in different coordinate systems. In the large separation limit, it is found that the order of the Casimir interaction energy is L-5, where L is the separation between the centers of the spheres. This order is intermediate between that of two Dirichlet spheres (of order L-3) and two Neumann spheres (of order L-7). In the small separation limit, we derive analytically the asymptotic expansion of the Casimir interaction energy up to the next-to-leading order term. The leading term agrees with the proximity force approximation. The result for the next-to-leading order term is compared to the corresponding results for scalar fields and electromagnetic fields. © 2015 American Physical Society. Source
