(
Elsevier Ltd
, 2014 , Article)
The work presented herein illustrates the use of computational intelligence and optimization approaches for improving the fuzzy controller's performance in architectural heating, ventilation, and air conditioning system ...
The impact of metal inert gas welding on the corrosion and mechanical behavior of AA 6061 T6
(
Electrochemical Science Group
, 2014 , Article)
An attempt has been made to investigate the effects of MIG welding on the corrosion and mechanical properties of AA 6061 T6. A series of experimental techniques has been conducted to evaluate the corrosion and mechanical ...
Comparison of various functionally graded femoral prostheses by finite element analysis
(
Hindawi
, 2014 , Article)
This study is focused on finite element analysis of a model comprising femur into which a femoral component of a total hip replacement was implanted. The considered prosthesis is fabricated from a functionally graded ...
Study on the impact of welding on the corrosion properties of AA 6061 T6
(
Trans Tech Publications Ltd
, 2014 , Article)
Aluminium alloy 6061 T6 circular specimens were joined using TIG welding method. AlMg5 was used as filler. The corrosion behavior of welded and un-welded AA 6061 T6 was investigated using potentiodynamic and open circuit ...
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, ...
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 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 ...
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 ...
Abandoned petroleum wells as sustainable sources of geothermal energy
(
Elsevier Ltd
, 2014 , Article)
A reliable heat transfer model was developed to determine the performance of a double pipe heat exchanger retrofitted to an abandoned petroleum well. The proposed model is compared against an analytical heat transfer model ...
