Modelling a Deposition Process in Collective Construction

Modelling and Experimental Study of Wax Deposition in Transportation Line Using a Flow Loop System

A fuzzy group decision making approach to construction project risk management

Implementation of the risk management concepts into construction practice may enhance the performance of project by taking appropriate response actions against identified risks. This research proposes a multi-criteria group decision making approach for the evaluation of different alternative response scenarios. To take into account the uncertainties inherent in evaluation process, fuzzy logic i...

Modelling the Role of Trail Pheromone in the Collective Construction of Termite Royal Chambers

Experiments with worker termites constructing a royal chamber around a termite queen in species Macrotermes subhyalinus (Rambur) have shown that both trail and cement pheromones are involved and necessary for the successful formation of pillars during the building process. However, earlier models of the construction were able to demonstrate stigmergic pillar formation with cement pheromone alon...

Multi-nozzle deposition for construction of 3D biopolymer tissue scaffolds

Purpose – To introduce recent research and development of biopolymer deposition for freeform fabrication of three-dimensional tissue scaffolds that is capable of depositing bioactive ingredients. Design/methodology/approach – A multi-nozzle biopolymer deposition system is developed, which is capable of extruding biopolymer solutions and living cells for freeform construction of 3D tissue scaffo...

An Investigation of Asphaltene Deposition Mechanisms During Natural Depletion Process by a Two Phase Modeling Using Genetic Algorithm Technique

In this work, the natural depletion process in sandstone and carbonate cores was modeled to investigate the asphaltene deposition mechanisms. A new permeability reduction correlation was proposed based on the Minssieux model that considers a combination of surface deposition, pore throat plugging, and filtration cake mechanisms. The results showed that the filtration cake is a dominant asphalte...
