Concrete, the most consumed man-made material worldwide, has shaped environment and modern world. Even though concrete is a major contributor to carbon footprint, it indispensable for building sustainable world of tomorrow. Researchers have been exploring ways reduce footprint implement strategical waste management plans in which wastes are repurposed. Pollution challenge almost all countries, ...

Abstract Paired comparisons are a popular tool for questionnaires in psychological marketing research. The quality of the statistical analysis of the responses heavily depends on the design, i.e. the choice of the alternatives in the comparisons. In this paper we show that the structure of locally optimal designs changes substantially with the parameters in the underlying utility. This fact is ...

This paper investigates the problem of allocation of database fragments to a network, so that the overall communication cost for processing a given set of transactions is minimized. Presented first is a data allocation algorithm with respect to a "simple strategy" to process transactions. Secondly, we present a dynamic data allocation algorithm which is guaranteed to produce a "locally optimal"...

response surface methodology was applied to determine the optimum processing conditions that lead to maximum water loss, weight reduction and minimum solid gain as well as water activity during osmotic dehydration of carrots. temperature (30-50?c), processing time (120-240 min), glucose syrup de=42 (30-50% w/w) and salt (5-15%) concentrations were the factors investigated with respect to water ...

The present paper deals with optimization of hybrid fiber reinforced plastic (FRP) laminated plates subjected to impact loading using island model parallel genetic algorithm (IMPGA). Finite element method (FEM) and IMPGA have been used to obtain optimum laminates in terms of minimizing the cost, weight or both cost and weight of Graphite/Epoxy (T300/5208)–Aramid/Epoxy (Kevlar 49) hybrid laminat...
