Accuracy comparison of post-processed PPP and real-time absolute positioning techniques
(Taylor and Francis Ltd., 2020)
The main motivation of this study is to assess the accuracy performance of the real-time global GNSS PPP positioning service, i.e. Trimble CenterPoint RTX, and online PPP post-processing service, i.e. CSRS-PPP, in Çorum ...
Energy, exergy, economic and environmental (4E) analyses of flat-plate and V-groove solar air collectors based on aluminium and copper
(Elsevier Ltd, 2017)
An experimental investigation has been carried out to study the effect of energy, economic, and environment of SACs which are smooth and roughened by v-groove protrusions arranged made of copper and aluminium materials. ...
Performance analysis of solar and solar-infrared dryer of mint and apple slices using energy-exergy methodology
(Elsevier Ltd, 2019)
In this study, double-pass solar air dryer (DPSAD) and infrared assisted double-pass solar air dryer (DPSAIRD) were designed and tested. The effects of using infrared energy have been experimentally investigated to ensure ...
Analysis of drying of melon in a solar-heat recovery assisted infrared dryer
(Elsevier Ltd, 2016)
Infrared drying systems are popular in terms of high heat and mass transfer. By using an infrared dryer, it is possible to catch fast heating and short drying time in comparison to the other drying methods. But it consumes ...
Permeability characteristics of superfine cement-grouted sand
(American Concrete Institute, 2017)
The aim of this research was to investigate the permeability of superfine cement-grouted sand. Initially, rheology of superfine cement suspensions was studied. The sedimentation and the setting time increased but the ...
The effect of blowing direction on heat sink performance by thermal imaging
(Yildiz Technical University, 2018)
Heat sinks (HSs) are designed for the mechanical, electrical and electronic components that generate heat in considerable amount. For this purpose, an aluminum conical pin fin heat sink is designed. Aluminum conical pin-fins ...
Effect of hyper-plasticizer additive rates on the properties of polypropylene fibre tempered concretes
(Springer, 2018)
In this study, effect of different rates of hyper-plasticizer additives on the physical and mechanical properties of polypropylene fibre tempered concretes was investigated. The factors of slump and compaction, which are ...
Use of waste concrete in cement production
(Springer, 2018)
Use of waste concrete in tempered cement production was examined in this study. Waste concretes were used in limestone-tempered cement production. In tempered cement production, 5, 10, 15, 20 and 28% milled waste concrete ...
Effects of holding force on the springback behavior of annealed aluminum plates
(Elsevier Ltd, 2016)
Typical V-bending process was performed to investigate the effects of holding force on springback behavior of 1050-H14 aluminum alloy plates annealed at 120 °C for 20 minutes. Tests were conducted on a universal testing ...
Examining the stream threshold approaches used in hydrologic analysis
(MDPI, 2018)
The stream threshold is a user-defined and important parameter that directly affects the drainage network and basin boundaries that would be obtained as a result of hydrological analysis. There have been several approaches ...
