Investigation of structural and tribological properties of duplex surface treated pure titanium
(Redakcia Kovove Materialy, 2016)
Commercial pure titanium (CP-Ti) is used in many engineering fields because of its superior properties such as excellent corrosion resistance, high strength/weight ratio, and biocompatibility. However, it is not available ...
Numerical solutions of linear differential-algebraic equation systems via Hartley series
(Amer Inst Physics, 2014)
In this paper, Hartley series are presented first. Then, the operational matrix of integration together with the product and coefficient matrices are presented. They are used to transform linear differential equation systems ...
An assessment of phenolic profiles, fatty acid compositions, and biological activities of two Helichrysum species: H. plicatum and H. chionophilum
(Wiley, 2020)
In the present study, we aimed to search and compare the biological activities of the ethanol (EtOH), methanol (MeOH), and ethylacetate (EtOAc) solvent extracts of the flower, stem, and root parts of two Helichrysum plants ...
Duplicated Audio Segment Detection with Local Binary Pattern
(IEEE, 2020)
Due to the advantages of convenience, and difficulty of detection, copy-move forgery is one of the most common audio forgery forms. It is significant to decide whether there is a duplicated segment in the audio. In order ...
Dynamic properties of sand-bitumen mixtures as a geotechnical seismic isolation material
(Elsevier Sci Ltd, 2020)
Geotechnical seismic isolation (GSI) has been emerged as an economical and alternative method in recent years that reduces earthquake that will affect the superstructure. Crumb rubber-granular soil mixtures (SRM) are ...
A simple regression based approach to estimate deformation modulus of rock masses
(Pergamon-Elsevier Science Ltd, 2015)
Rock mass characterization has a crucial importance in rock engineering applications including foundation design, slope design, support design and others. For these purposes, it is necessary to determine some input parameters ...
Biological activity of Psephellus appendicigerus as a natural agent
(Taylor & Francis Ltd, 2021)
Psephellus appendicigerus, is a plant endemic to Turkey, belonging to the Asteraceae family, which is traditionally used in folk medicine in Turkey. The aim of this study is to reveal for the first time the biological ...
PREPARATION AND CHARACTERIZATION OF BIODEGRADABLE RIGID POLYURETHANE FOAMS FROM THE LIQUEFIED EUCALYPTUS AND PINE WOODS
(Slovak Forest Products Research Inst, 2014)
In this study, eucalyptus (Eucalyptus camaldulensis L.) and pine (Pinus sylvestris L.) woods were liquefied using the the blended solvents mixture of polyethylene glycol PEG-400/glycerin in the presence of sulfuric acid ...
Formal Assessment and Measurement of Data Utilization and Value for Mines
(Springer Heidelberg, 2019)
Most contemporary mines have considerable amounts of data. Structured and unstructured large data sets are colloquially named big data. Much of the data in mining operations come from a variety of systems, each with different ...
Optimum shape design of shell structures
(Elsevier Sci Ltd, 2007)
A finite element-based shape optimization program has been developed for three-dimensional shell structures and the shape optimization of shell structures has been performed. The shape optimization program is implemented ...
