Global reverse supply chain design for solid waste recycling under uncertainties and carbon emission constraint
( Elsevier Ltd , 2017 , Article)The emergence of concerns over environmental protection, resource conservation as well as the development of logistics operations and manufacturing technology has led several countries to implement formal collection and ... -
Solving a large-scale integrated fleet assignment and crew pairing problem
( Springer New York LLC , 2017 , Article)Airline schedule planning problems are typically decomposed into smaller problems, which are solved in a sequential manner, due to the complexity of the overall problems. This results in suboptimal solutions as well as ... -
Constant and Random Full Backup Models with Incremental and Differential Backup Schemes
( World Scientific Publishing Co. Pte Ltd , 2017 , Article)It has been commonly known in a Database Management System that constant plans of incremental/differential backup schemes are set up and their full backups should be done to balance the costs of data backup and failure ... -
Nonlinear thermal buckling of axially functionally graded micro and nanobeams
( Elsevier Ltd , 2017 , Article)In this study, the nonlinear thermal buckling of axially functionally graded (AFG) Euler-Bernoulli micro/nanobeams is analyzed. The Eringen's nonlocal elasticity theory is used to develop the governing equations of nanobeam ... -
Energy absorption capabilities of complex thin walled structures
( Institute of Physics Publishing , 2017 , Conference)Thin walled structures have been used in the area of energy absorption during an event of a crash. A lot of work has been done on tubular structures. Due to limitation of manufacturing process, complex geometries were ... -
Collapse behavior of thin-walled corrugated tapered tubes
( Elsevier Ltd , 2017 , Article)Thin-walled structures have been widely used in energy absorption and safety applications such as automotive, due to their lightweight and progressive folding modes. This work studies the collapse behavior and energy ... -
Evaluating the Performance of a Newly Developed Carbon Capture Device for Mobile Emission Sources
( American Society of Mechanical Engineers (ASME) , 2017 , Article)In the present study, a new carbon capture device that can be carried on-board vehicles has been developed and tested. The developed device uses absorption and adsorption methods of postcombustion CO2 capture. Sodium ... -
Effect of synthesis conditions on ZnO thin film photosensitivity via mSILAR technique
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference)Zinc oxide (ZnO) nano-polycrystalline thin film has been synthesized by microwave-assisted successive ionic layer adsorption and reaction (mSILAR) technique. The prepared samples were annealed in air and an inert atmosphere. ... -
Detailed velocity profiles in close-coupled elbows-Measurements and computational fluid dynamics predictions (RP-1682)
( Taylor and Francis Inc. , 2017 , Article)This article presents a systematic study to measure detailed velocity profiles in close-coupled five-gore elbows having nominal diameters of 305�mm (12 in) and turning radii r/D = 1.5, and to, likewise, predict the velocity ... -
TDDFT studies on effects of the size on optoelectronic properties of 2D germanene sheets
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Conference)We report on the TDDFT calculations of the effect of the size on the optoelectronic properties of germanene sheets. Five structures of germanene were considered. All structures were optimized and their electronic and optical ... -
Effect of nanostructured polyhedral oligomeric silsesquioxane on the physical properties of poly(vinyl alcohol)
( John Wiley and Sons Inc. , 2017 , Article)An effective amphiphilic polyhedral oligomeric silsesquioxane (POSS) encapsulated poly(vinyl alcohol) (PVA) nanocomposite was successfully fabricated by solution blending method. Anionic octa(tetramethylammonium) (Octa-TMA) ... -
Investigation of lanthanum impregnated cellulose, derived from biomass, as an adsorbent for the removal of fluoride from drinking water
( Elsevier Ltd , 2017 , Article)High concentrations of fluoride in drinking water can cause the disease fluorosis. Our scope goal is to develop an effective biopolymeric adsorbent for the removal of fluoride to below a specific safety limit set by the ... -
Microton irradiation induced tuning of dielectric properties of nano ZnO-natural rubber disks
( Springer Verlag , 2017 , Article)The effect of electron beam irradiation of dielectric and conductivity properties of nano ZnO-natural rubber (NR) disks was investigated here. It is revealed that electric properties such as AC conductivity, dielectric ... -
Comparisons of replacement policies with periodic times and repair numbers
( Elsevier Ltd , 2017 , Article)Periodic replacement policies modeled with the history of minimal repairs have been studied extensively. However, in the viewpoint of cost rate, there is no literature to compare replacement polices which are carried out ... -
Performance Comparison Between Fast Fourier Transform-Based Segmentation, Feature Selection, and Fault Identification Algorithm and Neural Network for the Condition Monitoring of Centrifugal Equipment
( American Society of Mechanical Engineers (ASME) , 2017 , Article)This paper compares and evaluates the performance of two major feature selection and fault identification methods utilized for the condition monitoring (CM) of centrifugal equipment, namely fast Fourier transform (FFT)-based ... -
Replacement Policies for Periodic Damage Models
( World Scientific Publishing Co. Pte Ltd , 2017 , Article)A new periodic damage model is proposed in this paper, where the damage produced by shocks is only measured at periodic times, without considering the stochastic shocks and the cumulative process of damage in discrete ... -
