Elevated temperature, freezing-thawing and wetting-drying effects on polypropylene fiber reinforced metakaolin based geopolymer composites
(ELSEVIER SCI LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 2020)
In this study, metakaolin-based geopolymer samples produced by substitution of silica fume and colemanite waste up to 20% were subjected to high-temperature effects at 300, 600, 900 C, the wettingdrying effect of 5, 15 ...
A survey on one year strength performance of reinforced geopolymer composites
(ELSEVIER SCI LTD, THE BOULEVARD, LANGFORD LANE, KIDLINGTON, OXFORD OX5 1GB, OXON, ENGLAND, 2020)
Heat curing is a widely used method in geopolymer mortar production. While the heat curing shows an increase in strength values, the effect of this situation in the long term has not been examined sufficiently. In this ...
Scheduling of the Shuttle Freight Train Services for Dry Ports Using Multimethod Simulation-Optimization Approach
(SPRINGER INT PUBL AG, GEWERBESTRASSE 11, CHAM CH-6330, SWITZERLAND, 2021)
This paper introduces a simulation–optimization method for addressing scheduling problems for shuttle freight trains
(SFTs) in a shared railway corridor between a seaport and dry port. We use dispatching delays for ...

Simulation study of solar-source heat pump system with sensible energy storage
(SPRINGER, VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS, 2021)
A simulation study of the solar-source heat pump (SSHP) system that consists of solar collector group, heat exchanger (waterto-water), energy storage tank, heat pump with vapor compression and circulating pumps is carried ...
Determination of the Impact Damage Threshold Point of Composite Material Using Fuzzy-Base Taguchi Method
(ACADEMIC PUBLICATION COUNCIL, PO BOX 17225, KHALDIYA 72453, KUWAIT, 2020)
In this study, the impact damage threshold point of composite materials was determined using the optimum design
parameters obtained from the Fuzzy Based Taguchi Method (FBTM). It is known that both Taguchi and Fuzzy ...
Green Supplier Selection Using Fuzzy Multiple-Criteria Decision-Making Methods and Artificial Neural Networks
(HINDAWI LTD, ADAM HOUSE, 3RD FLR, 1 FITZROY SQ, LONDON W1T 5HF, ENGLAND, 2020)
In recent years, environmental awareness has increased considerably, and in order to decrease endangerments such as air and water
pollution, and also global warming, green procurement should be employed. *erefore, in the ...
