Development of cost-effective composite repair system for oil/gas pipelines
(
Elsevier Ltd
, 2018 , Article)
Fiber-reinforced composite repairs are becoming widely used as an alternative to the installation of welded, full-encirclement sleeves for repair of oil and gas transmission/transportation pipelines. The primary advantage ...
Beneficial effect of shot peening on steamside oxidation of 300-series austenitic steels: An electrochemical study
(
Elsevier B.V.
, 2018 , Article)
The formation of a protective oxide ensures the good corrosion resistance of austenitic steels in high temperature steam. However after long-term interaction even the protective oxide may tend to exfoliate and cause ...
Comparison between microwave and conventional sintering on the properties and microstructural evolution of tetragonal zirconia
(
Elsevier Ltd
, 2018 , Article)
In this research, the comparison between microwave sintering and conventional sintering on the mechanical properties and microstructural evolution of 3 mol% yttria-stabilised zirconia were studied. Green bodies were compacted ...
Experimental and theoretical studies on axially crushed corrugated metal tubes
(
Elsevier Ltd
, 2018 , Article)
In this paper, crushing behaviors of tube with shallow and deep corrugation are experimentally and theoretically examined under axial loading condition. Three types of specimens were tested under quasi static axial loading. ...
Biomechanical design of a composite femoral prosthesis to investigate the effects of stiffness, coating length, and interference press fit
(
Elsevier Ltd
, 2018 , Article)
Traditionally, high stiffness hip prostheses are associated with aseptic loosening. Hence, the effects of stiffness, coating length, and interference press fit on load sharing and micro-movements are investigated for a ...
Effect of microwave sintering on the properties of copper oxide doped Y-TZP ceramics
(
Elsevier Ltd
, 2018 , Article)
The effect of various amounts of copper oxide (CuO) up to 1 wt% on the densification behaviour and mechanical properties of 3 mol% yttria-tetragonal zirconia polycrystal (Y-TZP) were studied by using microwave (MW) sintering ...
A clustering-based repair shop design for repairable spare part supply systems
(
Elsevier Ltd
, 2018 , Article)
In this study, we address the design problem of a single repair shop in a repairable multi-item spare part supply system. We propose a sequential solution heuristic to solve the joint problem of resource pooling, inventory ...
Exact methods for the quay crane scheduling problem when tasks are modeled at the single container level
(
Elsevier Ltd
, 2018 , Article)
The scheduling of quay cranes (QCs) to minimize the handling time of a berthed vessel is one of the most important operations in container terminals as it impacts the terminal's overall productivity. In this paper, we ...
A matheuristic for the asymmetric capacitated vehicle routing problem
(
Elsevier B.V.
, 2018 , Article)
In this paper, we propose a novel matheuristic for the Asymmetric Capacitated Vehicle Routing Problem (ACVRP). This optimization-based approach combines some heuristic concepts with compact mixed-integer linear programming ...
Optical characterization of tip bended Vertically Aligned Carbon Nanotubes array
(
Elsevier B.V.
, 2018 , Article)
Vertically Aligned Carbon Nanotube arrays (also termed as VACNTs or CNT forest) have recently found to be transformable to a reflective mirror from a naturally black absorber. The feature of improved reflectance can be ...
