A selective approach to index term weighting for robust information retrieval based on the frequency distributions of query terms
(Springer, 2019)
A typical information retrieval (IR) system applies a single retrieval strategy to every information need of users. However, the results of the past IR experiments show that a particular retrieval strategy is in general ...
Nb-Pd-Ti BCC thin films for hydrogen separation
(Elsevier Science Sa, 2019)
An investigation was carried out into Nb-Pd-Ti ternary system to determine possible body-centered cubic (b.c.c.) membranes that can be used for hydrogen separation. A library of thin films was produced covering the greater ...
Optimal operation of a multi-energy system considering renewable energy sources stochasticity and impacts of electric vehicles
(Pergamon-Elsevier Science Ltd, 2019)
Electrical, heating and cooling energy demands of the end users are increasing day by day. For the sake of using fewer fossil fuels, decreasing the energy costs and gas emissions as well as increasing the efficiency and ...
Influence of time-dependency on elastic rock properties under constant load and its effect on tunnel stability
(Techno-Press, 2020)
In structures excavated in rock mass, load progressively increases to a level and remains constant during the construction. Rocks display different elastic properties such as E-i and v under different loading conditions ...
Hydroclimate in Africa during the Medieval Climate Anomaly
(Elsevier, 2018)
The Medieval Climate Anomaly (MCA) is a recognized period of distinct pre-industrial climate change, with a core period of 1000-1200 CE. The field of palaeoclimatology has made major progress over the past 15 years during ...
Effect of Defect Size on Subsurface Defect Detectability and Defect Depth Estimation for Concrete Structures by Infrared Thermography
(Springer/Plenum Publishers, 2017)
This study aims to reveal the effect and correlation of delamination size and defect shape for using infrared thermography (IRT) through FE modeling to enhance the reliability and applicability of IRT for effective structural ...
Use of Pinched Sluice in Albite Concentration
(Polish Mineral Eng Soc, 2017)
Albite (NaAlSi3O8) is an important industrial mineral especially for ceramic and glass production. Major Fe-containing impurity of albite ore is flaky mica minerals. This study was conducted to determine the applicability ...
Synthesis of c-axis oriented AlN thin films at room temperature
(Taylor & Francis Ltd, 2017)
In this study, aluminium nitride (AlN) thin films were synthesised by plasma-enhanced reactive DC magnetron sputtering on glass and Si (100) substrates and the effect of bias voltages on the structural, optical and ...
TANNIC ACID AS A HYDROPHOBICITY MODIFIER FOR GALENA IN THE PRESENCE OF METAL IONS
(Oficyna Wydawnicza Politechniki Wroclawskiej, 2017)
This study was performed to determine the effect of tannic acid (TA) on hydrophobicity of galena using Taguchi's design of experimental methodology. Roles of metal ions, dithiophosphinate (DTPI) concentration, and conditioning ...
Comprehensive Optimization Model for Sizing and Siting of DG Units, EV Charging Stations, and Energy Storage Systems
(Ieee-Inst Electrical Electronics Engineers Inc, 2018)
The sizing and siting of renewable resources-based distributed generation (DG) units has been a topic of growing interest, especially during the last decade due to the increasing interest in renewable energy systems and ...
