Modular programming has the usual benefits associated with structured programming, information hiding and reusability, but also has additional benefits to offer when applied in agent programming. We argue that modules can be viewed as structures similar to that of policy-based intentions [2]. Modules perceived in this way are components within an agent that are triggered in a particular situati...
A novel catalytic packing in biodiesel production using a monolithic structured support catalyst is studied. Calcium oxide (CaO) is chosen as the wash coat due to its well established property as a good catalyst. The experiment for the monolithic CaO (4 cm dia, 6 cm height and 400 cell inch -2 ) was performed in a 1000 mL monolithic reactor while the CaO powder experiment was carried out in a 1...
In this note, we exhibit a weakly holomorphic modular form for use in constructing Fourier eigenfunction four dimensions. Such auxiliary functions may be of to the D4 checkerboard lattice and dimensional sphere packing problem.
A cryogenic pilot distillation column operating at total reflux is described. It was used to measure the pressure drop and flooding of various structured packings, first using pure nitrogen and then using an oxygen-argon mixture. By varying the pressure, the nitrogen system was used to characterize the capacity of each packing via Wallis plots. The oxygen-argon flooding data can be accurately p...
Column packings applicable to the field of rectification are mainly characterised by their number of theoretical stages per meter NTSM [1/m], specific pressure drop ∆p [mbar/m] and capacity limits. A set of dimensionless numbers are derived by means of a simple model of dry gas flow within parallel plates (slit flow). These numbers are dimensionless and allow the comparison of measured values f...
We obtain new restrictions on the linear programming bound for sphere packing, by optimizing over spaces of modular forms to produce feasible points in dual program. In contrast situation dimensions 8 8</m...
An electronic representation of Sulzer’s Mellapak N250Y structured packing was generated by subjecting a physical packing element to CT scan. The resulting file was imported into a three-dimensional imaging program and then copied, translated, and rotated to create a stack of three packing elements. This stack was then inserted into an open-ended cylindrical surface to approximate a packed colu...
