Mixture optimisation for cement-soil mixtures with embedded GFRP tendons

چکیده
The glass fiber-reinforced polymer (GFRP) rebar reinforced cemented soil is widely employed to solve the weak foundation problem led by sludge particularly. robustness of this structure highly dependent on interface bond strength between GFRP tendon and soils. However, its application obstructed owing deficient studies influence factors. Therefore, study investigates effects water content ( C w : 50%–90%), cement proportion c 6%–30%), curing period T 28–90 days) peak residual strengths p t ), as well unconfined compression (UCS). Results indicated that mechanical properties were positively responded , while negatively correlated . Besides, Random Forest (RF), one machine learning (ML) models, was developed with hyperparameters tuned firefly algorithm (FA) based experimental dataset. pullout predicted ML model for first time. High correlation coefficients low root-mean-square errors verified accuracy established RF-FA models in study. Subsequently, a coFA-based multi-objective optimisation (MOFA) introduced optimise tri-objectives UCS, (or cost. Pareto fronts successfully acquired optimal mixture designs, which contributes practice. In addition, sensitivity input variables evaluated ranked.

Calcium Enriched Mixture Cement
A review of the existing literature was performed by using electronic and hand searching methods for CEM cement from January 2006 to December 2013. CEM cement has a different chemical composition from that of mineral trioxide aggregate (MTA) but has similar clinical applications. It combines the biocompatibility of MTA with more efficient characteristics, such as significantly shorter setting t...
متن کاملProgramming Optimisation for Embedded Vision
Increasing demand in mobile computing and multimedia market as well as other embedded devices has made it necessary to develop computer vision techniques which are more appropriate for these systems. This paper firstly analyses requirements for embedded vision systems and issues involved in programming optimisation to meet these requirements. Two case studies are then presented together with th...
متن کاملAn argument for simple embedded ACL optimisation
The difficulty of efficiently reordering the rules in an Access Control List is considered and the essential optimisation problem formulated. The complexity of exact and sophisticated heuristics is noted along with their unsuitability for real time implementation embedded in the hardware of the network device. A simple alternative is proposed, in which a very limited rule reordering is consider...
