Suggestion of an Indicator to Evaluate Material Deposition in Resistance Spot Welding: Weld-Surface Interaction Index
(Springer, 2018)
Resistance spot welding (RSW) is still leading joining process in the automotive industry due to the simplicity and speed of the process. On the other hand, galvanized steel sheets provide improvement in corrosion resistance ...
Photovoltaic performance and photostability of anthocyanins, isoquinoline alkaloids and betalains as natural sensitizers for DSSCs
(Pergamon-Elsevier Science Ltd, 2018)
Natural dyes extracted from fruit (FBV) and root (RBV) of barberry (Berberis vulgaris) and fruit (FPA) and stalk (SPA) of pokeweed (Phytolacca americana) were used as sensitizers for dye-sensitized solar cells (DSSCs). All ...
Iron doped ZnO thin films deposited by ultrasonic spray pyrolysis: structural, morphological, optical, electrical and magnetic investigations
(Springer, 2018)
In this work, undoped and Fe-doped ZnO thin films at various concentrations (2, 4 and 6 at.%) were deposited onto glass substrate by using ultrasonic spray pyrolysis in order to investigate the effect of Fe doping on the ...
An investigation of surface properties of thermally modified wood during natural weathering for 48 months
(Elsevier Sci Ltd, 2018)
Weathering period and exposure conditions can affect the degradation rate of wood surfaces. Longer weathering exposure periods are more reliable for end-use performance evaluations, and therefore it is desirable to investigate ...
The effect of energy resolution of detection instrument on mass attenuation coefficient
(Iop Publishing Ltd, 2018)
The effect of energy resolution of two detection systems, HPGe and NaI(T1), was determined by Monte Carlo (MC) calculation on mass attenuation coefficients of magnesium (Mg) and tungsten (W). In order to reveal the energy ...
Change in Porosity of A356 by Holding Time and Its Effect on Mechanical Properties
(Springer, 2018)
In most of the practical casting operations, it is important to be able to cast large number of part with one single melt. Therefore, when quantity of the charge and melting crucible is increased, during casting process, ...
Performance Assessments of Organic Rankine Cycle With Internal Heat Exchanger Based on Exergetic Approach
(Asme, 2018)
This study makes energy and exergy analysis of a sample organic Rankine cycle (ORC) with a heat exchanger which produces energy via a geothermal source with a temperature of 140 degrees C. R600a is preferred as refrigerant ...
Optimization of ultrasound-assisted extraction of phenolic compounds from grapefruit (Citrus paradisi Macf.) leaves via D-optimal design and artificial neural network design with categorical and quantitative variables
(Wiley, 2018)
BACKGROUND: The extraction of phenolic compounds from grapefruit leaves assisted by ultrasound-assisted extraction (UAE) was optimized using response surface methodology (RSM) by means of D-optimal experimental design and ...
A novel approach to selecting a competition index: the effect of competition on individual-tree diameter growth of Calabrian pine
(Canadian Science Publishing, Nrc Research Press, 2018)
In this study, we evaluated the performance of 18 competition indices composed of nine distance-dependent and nine distance-independent indices in explaining the variation in individual-tree diameter growth of Calabrian ...
Emotion recognition based on time-frequency distribution of EEG signals using multivariate synchrosqueezing transform
(Academic Press Inc Elsevier Science, 2018)
This paper investigates the feasibility of using time-frequency (TF) representation of EEG signals for emotional state recognition. A recent and advanced TF analyzing method, multivariate synchrosqueezing transform (MSST) ...
