Forecasting copper price using gene expression programming
Forecasting the prices of metals is important in many aspects of economics. Metal prices are also vital variables in financial models for revenue evaluation, which forms the basis of an effective payment regime using resource policymakers. According to the severe changes of the metal prices in the recent years, the classic estimation methods cannot correctly estimate the volatility. In order to...
متن کاملEffect of Synthesis Parameters on the Compressive Strength of Fly Ash Based Geopolymer Concrete
The paper presents the effect of different synthesis parameters, such as (a) fly ash to alkaline solution ratio, (b) concentration of NaOH solution, (c) concentration of sodium silicate solution, (d) geopolymer solids to water ratio and (e) sodium silicate to sodium hydroxide solution ratio, on the compressive strength of geopolymer concrete synthesized from fly ash of Indian origin. It is obse...
متن کاملModeling the compressive strength of geopolymeric binders by gene expression programming-GEP
GEP has been employed in this work to model the compressive strength of different types of geopolymers through six different schemes. The differences between the models were in their linking functions, number of genes, chromosomes and head sizes. The curing time, Ca(OH)2 content, the amount of superplasticizer, NaOH concentration, mold type, aluminosilicate source and H2O/Na2O molar ratio were ...
متن کاملCompressive Strength and Workability Characteristics of Low-Calcium Fly ash-based Self-Compacting Geopolymer Concrete
Due to growing environmental concerns of the cement industry, alternative cement technologies have become an area of increasing interest. It is now believed that new binders are indispensable for enhanced environmental and durability performance. Self-compacting Geopolymer concrete is an innovative method and improved way of concreting operation that does not require vibration for placing it an...
متن کاملthe effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
