Pectin is a complex polysaccharide and natural food additive extracted from citrus peel and apple pomace in the form of brownish powder. It is widely used as a jelling and thickening agent and the food industry especially in jams and jellies. It is also recommended for use as fat replacer and also lowers blood cholesterol by increasing viscosity in the intestinal tract thus lowering cholesterol...

Valorisation of lignin plays a key role in the further development of biorefinery processes for biofuels and the production of biobased materials from lignocellulosic biomass. Today’s increased demand for alternatives to fossil carbon based products, such as the production of transportation biofuels and bulk “green” chemicals, expands the interest and the need to create added value to the uncon...

We consider the following stochastic bandwidth packing process: the requests for communication bandwidth of different sizes arrive at times t = 0, 1, 2, . . . and are allocated to a communication link using “largest first” rule. Each request takes a unit time to complete. The unallocated requests form queues. Coffman and Stolyar [6] introduced this system and posed the following question: under...

This paper presents an integrated simulation-based optimization system that incorporates the design of computer experiments, the Gaussian process (GP) for regression, a multi-objective genetic algorithm (GA), and levels of adjacency to adaptively and automatically search Pareto-optimal solutions for different objectives. Selecting the optimal process conditions for the injection molding process...
