The effects of freeze-thaw cycles and block size on the use of the Gümüşhane Granitoid (Gümüşhane/Turkey) as building stone
(Springer, 2021)
The present study aims to examine the usability of the Gümüşhane Granitoid as a building stone taking into consideration the short-term freeze-thaw cycles and mean block volume. A total of 180 specimens were used in the ...
Pozzolanic properties of trachyte and rhyolite and their effects on alkali-silica reaction
(Techno-Press, 2021)
The alkali-silica reaction (ASR) is a highly complex chemical reaction which causes damage to concrete and thus adversely affects the durability and service life. Significant damage can occur in concrete structures due to ...
Machine learning models to estimate the elastic modulus of weathered magmatic rocks
(Springer, 2021)
In recent years, several soft computing models have been proposed to estimate the elastic modulus of magmatic rocks. However, there are lacks in models that consider the different weathering degrees in determining the ...
Selecting the best forensic report by using a group decision making method: A case study on three forensic reports
(IEEE, 2021)
Group decision making (GDM) techniques have been very popular to take the best and the most convenient decision from an alternative set. GDM techniques have been applied in various area of information sharing as well as ...
Investigation of thermoelectric cooler system effect on induction motor performance
(Institute of Electrical and Electronics Engineers Inc., 2021)
Induction motors are generally cooled by the fan connected to the motor shaft, as the cooling of electrical machines is important. In this study, an alternative method is proposed for cooling of induction motors. Thermoelectric ...
Sodium silicate effect on setting properties, strength behavior and microstructure of cemented coal fly ash backfill
(Elsevier, 2021)
Representing an engineered mixture of coal fly ash, cement and water, cemented coal fly ash backfill (CCB) is typically employed for filling the openings created after coal excavation in the earth. A high rate of productivity ...
Thermal energy storage performance of PCM/graphite matrix composite in a tube-in-shell geometry
(Elsevier, 2021)
Melting heat transfer performance and measuring energy storage efficiency via total melting time of PCM/ graphite matrix in a tube-in-shell for solar thermal energy storage and recovering waste heat applications is studied ...

(Scitepress, 2021)
Use of online social network platforms has increased over last decades. There are various activities that users can do on those platforms such as, making friends, enjoying time, making business, and education. Given ...
A simplified method to determine carrier transport mechanisms of metal-oxide resistive random access memory (RRAM) devices
(Elsevier, 2021)
The current carrier transport mechanism in non-linear resistance states of the current-voltage (I-V) curves of the resistance changing or resistive switching (RS) based random access memory (RRAM) devices would help to ...
Current technologies for aluminum castings and their machinability
(Elsevier, 2021)
Metal casting is one of the leading production techniques for three-dimensional parts in manufacturing industry. The casting process consists of many stages such as design, determination of chemical composition (alloying), ...
