Biyoakustik ses verileri üzerinde çeşitli sınıflandırıcı algoritmalarının temel bileşen analizi kullanılarak performans karşılaştırması
(IEEE (Institute of Electrical and Electronics Engineers), 2019)Doğal ortamlarda alınan seslerin tanınması laboratuvar ortamında alınan veya yapay olarak oluşturulan seslerin tanınmasından daha zordur. Özellikle benzer canlıların çıkardıkları sesler tanınmayı zorlaştıran bir etkendir. ... -
Burr measurement method based on burr surface area
(Korean Society for Precision Engineering, 2020)One of the major issues of drilling operations pertains to the formation of burrs, which greatly influences the accuracy of the manufactured parts, and, thus, the capability to meet the desired performance of the part. To ... -
Determination of energy value and ash-sulfur content of clean fuel obtained from lignite carbonization at different heating rates
(2021)Carbonization (low-temperature pyrolysis) is an economical and efficient method used to obtain solid products from lignite and improve calorific value. This research focused on the morphological and structural properties ... -
Determination of tensile strength of cementitious composites using fracture parameters of two-parameter model for concrete fracture
(Elsevier, 2022)In this study, the formulation of the two-parameter model based on the size effect proposed by previous researchers was initially improved to be much more practical. Subsequently, six series of notched and unnotched beams ... -
Effect of fly ash and marble powder on and flow properties and compressional strength of grouts
(Baski, 2019)Coal fly-ash and marble powders are two environmentally important industrial waste materials that should be utilized. It is known that they are used as additives in concrete production for many years. In this study, the ... -
Highly Active Fe3O4@SBA-15@NHC-Pd Catalyst for Suzuki–Miyaura Cross-Coupling Reaction
(Springer, 2021)A novel Pd-NHC functionalized magnetic Fe3O4@SBA-15@NHC-Pd was synthesized and used as an efficient heterogeneous catalyst in the Suzuki–Miyaura C–C bond formation reactions. The Fe3O4@SBA-15@NHC-Pd characterized by X-Ray ... -
Modeling of the effect of falcon concentrator parameters on lignite deashing with Taguchi orthogonal design
(Taylor & Francis, 2021)In this study, the deashing of Sivas-Kangal (Turkey) lignite was carried out under different conditions. Solids ratio (20%, 30%, 40% and 50% by weight), centrifugal force (20, 100, 176 and 300 G), feed rate (0.5, 1.0, 1.5 ... -
N-heterocyclic carbene Pd(II) complex supported on Fe3O4@SiO2: Highly active, reusable and magnetically separable catalyst for Suzuki-Miyaura cross-coupling reactions in aqueous media
(Elsevier, 2021)A new type magnetic nano Fe3O4@SiO2@NHC@Pd-MNPs heterogeneous catalyst was fabricated and characterized by Fourier Transform Infrared (FTIR) spectroscopy, Transmission Electron Microscopy (TEM), X-Ray Diffraction (XRD), ... -
Residual strength prediction based on size effect of cracked concrete members
(ICE Publishing, 2021)In engineering materials, defects, such as cracks, may occur during production and/or owing to various reasons. One of the aims of fracture mechanics is to determine the fracture toughness-based residual strength of ... -
Use of water quality index and multivariate statistical methods for the evaluation of water quality of a stream affected by multiple stressors: A case study
(Elsevier, 2020)Therefore, water quality of the stream is of great importance. In this study, multivariate statistical techniques (MSTs) and water quality index (WQI) were applied to assess water quality of the stream affected by multiple ...
