An adaptive step-down procedure for fault variable identification
( Taylor & Francis , 2015 , Article)In a process with a large number of process variables (high-dimensional process), identifying which variables cause an out-of-control signal is a challenging issue for quality engineers. In this paper, we propose an adaptive ... -
Design development of aggregates cooling systems for hot weather concreting
( Springer Netherlands , 2015 , Article)Using hot aggregates, in concrete production, results in a drop in compressive strength of the produced concrete. Various methods have been proposed for cooling concrete aggregates. This paper proposes new two designs for ... -
Effect of microstructural evolution on wettability and tribological behavior of TiO2 nanotubular arrays coated on Ti–6Al–4V
( Elsevier Ltd , 2015 , Article)Self-organized TiO2 nanotubular arrays were fabricated by electrochemical anodization of Ti–6Al–4V plates in an NH4F/H3PO4 electrolyte. The effect of microstructural evolutions on the wettability and tribological behavior ... -
Energy absorption capability of thin-walled aluminium tubes under crash loading
( Universiti Malaysia Pahang , 2015 , Article)This paper investigates the interaction of design factors such as tube thickness, tube length, and tube cross-sectional aspect ratio, along with friction and impacting mass on crashworthiness parameters such as specific ... -
Enhanced simulated-annealing-based algorithms and their applications to process planning in reconfigurable manufacturing systems
( Elsevier, Ltd , 2012 , Article)Capabilities of enhanced simulated-annealing-based algorithms in solving process planning problems in reconfigurable manufacturing are investigated. The algorithms are enhanced by combining variants of the simulated annealing ... -
From Zirconium Nanograins to Zirconia Nanoneedles
( Nature Publishing Group , 2016 , Article)Combinations of three simple techniques were utilized to gradually form zirconia nanoneedles from zirconium nanograins. First, a physical vapor deposition magnetron sputtering technique was used to deposit pure zirconium ... -
Multiple parts process planning in serial-parallel flexible flow lines: part I—process plan modeling framework
( Springer London , 2015 , Article)In recent years, integrated process planning and scheduling models have been proposed as solutions that can bridge the gap between practical process planning and production scheduling. However, most structures of these ... -
Self-organized TiO2 nanotube layer on Ti–6Al–7Nb for biomedical application
( Elsevier B.V. , 2015 , Article)In the present study, a self-organized nanotube TiO2 layer on Ti–6Al–7Nb was fabricated. The influence of acidic electrolytes including glycerol (G) and ethylene glycol (EG) on the anodization, microstructural features and ... -
Spiderweb Honeycombs
( Elsevier Ltd , 2015 , Article)Small and large deformation in-plane elastic response of a new class of hierarchical fractal-like honeycombs inspired by the topology of the “spiderweb” were investigated through analytical modeling, detailed numerical ... -
Structural and morphological study of mechanochemically synthesized crystalline nanoneedles of Zr-doped carbonated chlorapatite
( Elsevier B.V. , 2015 , Article)Nanosize Zr-doped carbonated chlorapatite (n-ZCCA) was developed as a novel bioceramic by a ball milling process. Results showed that the microstructural characteristics of the product were affected significantly by the ... -
Thermo elastic analysis of functionally graded rotating disks with temperature-dependent material properties: uniform and variable thickness
( Springer Science+Business Media, B.V. , 2009 , Article)A thermo elastic analysis is presented for axisymmetric rotating disks made of functionally graded material (FGM) with variable thickness. Material properties are assumed to be temperature-dependent and graded in the radial ... -
TiO2 nanotube coating on stainless steel 304 for biomedical applications
( Elsevier Ltd , 2015 , Article)The present study describes the anodic growth of TiO2 nanotube thin layer on stainless steel 304 in ethylene glycol/water/ammonium fluoride electrolyte. In this regard, pure titanium was coated on stainless steel 304 ... -
Wear resistance investigation of titanium nitride-based coatings
( Elsevier Ltd , 2015 , Article)The wear of components while they are in service is a predominant factor controlling the life of machine components. Metal parts are often damaged because of wear-driven failures causing the loss of dimensions and ...
