Application of Ni and Cu nanoparticles in transient liquid phase (TLP) bonding of Ti-6Al-4V and Mg-AZ31 alloys
(
Springer US
, 2014 , Article)
The transient liquid phase (TLP) bonding of Ti-6Al-4V alloy to a Mg-AZ31 alloy was performed using an electrodeposited Ni coating containing a dispersion of Ni and Cu nanoparticles. Bond formation was attributed to two ...
A continuum model with a percolation threshold and tunneling-assisted interfacial conductivity for carbon nanotube-based nanocomposites
(
American Institute of Physics Inc.
, 2014 , Article)
A continuum model that possesses several desirable features of the electrical conduction process in carbon-nanotube (CNT) based nanocomposites is developed. Three basic elements are included: (i) percolation threshold, ...
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 ...
PS/TiO2 (polystyrene/titanium dioxide) composite nanofibers with higher surface-to-volume ratio prepared by electrospinning: Morphology and thermal properties
(
John Wiley & Sons, Ltd.
, 2013 , Article)
Polystyrene (PS)/Titanium dioxide (TiO2) composite nanofibers were prepared by electrospinning of PS/TiO2 solution in N,N-dimethylformamide (DMF). The effect of PS and TiO2 concentration on the morphology and thermal ...
A dynamic MOPSO algorithm for multiobjective optimal design of hybrid renewable energy systems
(
John Wiley and Sons Ltd
, 2014 , Article)
In this paper, a dynamic multiobjective particle swarm optimization (DMOPSO) method is presented for the optimal design of hybrid renewable energy systems (HRESs). The main goal of the design is to minimize simultaneously ...
A new compact formulation for the daily crew pairing problem
(
INFORMS Inst.for Operations Res.and the Management Sciences
, 2019 , Article)
The daily crew pairing problem (DCPP) seeks to generate a set of minimal-cost pairings that covers all the planned daily flights while complying with a variety of labor regulations, safety rules, and policies of the airline. ...
A preemptive bound for the Resource Constrained Project Scheduling Problem
(
Springer US
, 2014 , Article)
The Resource Constrained Project Scheduling Problem is one of the most intensively investigated scheduling problems. It requires scheduling a set of interrelated activities, while considering precedence relationships, and ...
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 ...
Mechanical and microstructure characterization of hard nanostructured N-bearing thin coating
(
Associazione Italiana di Metallurgia
, 2015 , Article)
Tools for machining are made of hard steels and cemented carbide (WC-Co). For specialized applications, such as aluminium
machining, diamond or polycrystalline cubic boron nitride are also used. The main problem with ...
Optimal replacement last with continuous and discrete policies
(
Institute of Electrical and Electronics Engineers Inc.
, 2014 , Article)
This paper proposes age and periodic replacement last models with continuous, and discrete policies. That is, an operating unit is replaced preventively at time T of operation as a strategic policy, or at a number N of ...
