Termination Agreement

We solve a binary distillation problem using the solution of a Riccati equation. We find that four plates are needed to achieve the desired product purity. We also compute the number of stages with the classical approach by stepping off stages using the equilibrium curve and the operating line....

The bridge-crossing problem is a mathematical puzzle wherea group of N persons have to cross a bridge at night. It is dark and they can only cross the bridge if they carry a lamp. Only one lamp is available and at most two persons can cross at the same time. It is not possible to cross from a...

The program computes the velocity and temperature profiles for free convection past an isothermal vertical plate. Results are obtained after solving two coupled nonlinear differential equations. The shooting method is used to obtain the boundary conditions, required to solve the coupled ODEs,...

Three factors interfere in the determination of pellet mean size. These are the impeller speed, the binding solution and the pelletization time. We use experimental design (Doehlert design) to predict pellet mean size versus the three factors. We determine the quadratic model by multi-linear...

Programs and utility functions using the Symbolic Math Toolbox are provided to analyze vectors and tensors in general curvilinear coordinates. The programs perform the following functions: 1) runcoord plots intersecting coordinate surfaces for typical coordinate systems 2) runmetric computes and...

Membrane diffusion in a coupled reactor system can cause complex behaviour such as oscillations, period doubling and chaos. Here we study a simple model suggested by Deng-Harrison in 1969. The bifurcation diagram is obtained. We find good agreement with Figure 10 page 76 of the paper by Lengyel...

We use the genetic algorithm (gatool) to determine the three parameters of the simple Antoine equation and the six parameters of the Modified Antoine Model. Predictions are in perfect agreement with experimental data of vapor pressure of ethanol versus temperature for a temperature range from...

We compare computed temperature distributions using both pdepe and analytical solutions for different geometries (slab, cylinder and sphere). Solids are kept initially at uniform temperature. For t>0, the boundary surface is kept at constant temperature. Results show excellent agreement....

Fleiss'es kappa is a generalization of Scott's pi statistic, a statistical measure of inter-rater reliability. It is also related to Cohen's kappa statistic. Whereas Scott's pi and Cohen's kappa work for only two raters, Fleiss'es kappa works for any number of raters giving categorical ratings...

the AFSA includes five steps of operations: (1) behaviour selection, (2) searchingbehaviour, (3) swarming behaviour, (4) following behaviour and (5) bulletin. A `max-generation' is the trial number of an AF school searching for food under given initialconditions, which is one of the widely used...

The plane stress problem i.e a plate under uniform tension at its edges is solved. Plate is dicretized using isoparametric Q4 elements. Pre-processing is done using a standard FEM software. 2nd order Gaussian integration is used to get stiffness matrix. Results obtained are compared with standard...

Calculates Krippendorff's Alpha as a measure of inter-rater agreement. Krippendorff's Alpha is a measure of inter-rater agreement, measuring how much raters (labellers, coders) agree on labels assigned to items. It operates on different levels of measurement, implemented are nominal, ordinal and...
