Advanced Engineering Materials, EarlyView.The corrosion performance of AlSi7Mg and AlSi10Mg alloys produced through selective laser melting (SLM) was examined under compressive stress in a chloride environment. Electrochemical analyses, including open‐circuit potential (OCP), potentiodynamic polarization (CPP), and electrochemical impedance spectroscopy (EIS), were complemented by scanning ...

Two sharp inequalities for operators in a Hilbert space
Researches in Mathematics, 2022 In this paper we obtained generalisations of the L. V. Taikov’s and N. Ainulloev’s sharp inequalities, which estimate a norm of function's first-order derivative (L. V. Taikov) and a norm of function's second-order derivative (N.

Comparative Study of Shear Modulus in Calcareous Sand and Sabkha Soils
, 2012 The estimation of various soil moduli has always been a fundamental component of geotechnical engineering. Since most design works involve assessment of ground response to stress applications, an accurate estimate of the soil modulus is deemed imperative

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Fabrication of Bamboo Fiber Paper with Shellac and Its Effect on Specific Elastic Modulus
Journal of the Society of Materials Science, Japan, 2011 Specific elastic modulus of bamboo fiber paper was evaluated when the shellac was added into the paper during the paper making process. For the fabrication of the paper, bamboo fibers were treated with the alkali solution after extraction. The bamboo paper was fabricated with a heat pressing technique using the wet bamboo fibers sheet obtained by the ...

A Blind Synchronous Multi-User DS-CDMA Equaliser With Partial Loading
, 2004 In this paper, we propose a blind multiuser detection scheme in a direct sequence CDMA downlink scenario by means of a chip-level equaliser, which can be updated even if not all possible users are active, i.e. the system is partially loaded.
