Evaluation of thermal history and defect in friction stir processing of as-cast magnesium AZ91
(
Trans Tech Publications Ltd
, 2018 , Conference Paper)
Friction stir processing (FSP) is a thermos-mechanical process for modifying the microstructural and material properties of metals. FSP also can be used for mechanical alloying and producing metal matrix composites. Due ...
A theoretical and experimental study of fast lower bounds for the two-dimensional bin packing problem
(
EDP Sciences
, 2018 , Article)
We address the two-dimensional bin packing problem with fixed orientation. This problem requires packing a set of small rectangular items into a minimum number of standard two-dimensional bins. It is a notoriously intractable ...
Towards achieving nanofinish on silicon (Si) wafer by ?-wire electro-discharge machining
(
Springer London
, 2018 , Article)
This study investigates the use of nanopowder-mixed dielectric oil and temporary metallic coating on highly doped Si sample to achieve nanometric surface roughness using ?-WEDM operation. To achieve this, two different ...
Monitoring multistage processes with autocorrelated observations
(
Taylor and Francis Ltd.
, 2017 , Article)
In multistage manufacturing processes, autocorrelations within stages over time are prevalent and the classical control charts are often ineffective in monitoring such processes. In this paper, we derive a linear state ...
Synthesis and characterization of magnetic nanostructured lipid carriers (mNLCs) for drug delivery
(
Electrochemical Science Group
, 2018 , Article)
Magnetic nanoparticles (MNPs) are a class of nanoparticles, which can be manipulated using magnetic fields. Currently, MNPs are recognized as one of the most important mode as a drug carrier while they can also be potentially ...
Investigating the effect of utilizing new induction manifold designs on the combustion characteristics and emissions of a direct injection diesel engine
(
American Society of Mechanical Engineers (ASME)
, 2018 , Article)
New induction manifold designs have been developed in this work to enhance the turbulence intensity and improve the mixing quality inside diesel engine cylinders. These new designs employ a spiral-helical shape with three ...
Band Gap Characteristics of Nonrotating Passive Periodic Drill String
(
American Society of Mechanical Engineers (ASME)
, 2018 , Article)
A new class of drill strings is investigated whereby strategically designed and placed periodic inserts are utilized to filter out the vibration transmission along the drill strings. Such mechanical filtering capabilities ...
Hydrogels for Advanced Stem Cell Therapies: A Biomimetic Materials Approach for Enhancing Natural Tissue Function
(
Institute of Electrical and Electronics Engineers
, 2018 , Article)
Stem-cell-based therapy is a promising approach for the treatment of a myriad of diseases and injuries. However, the low rate of cell survival and the uncontrolled differentiation of the injected stem cells currently remain ...
Using hierarchical composite approach to improve mechanical response of Mg and Mg–Bi2O3 nano-composites
(
Elsevier, Ltd
, 2013 , Article)
Novel Mg nano-composites reinforced with either Bi2O3 nano-particles or hybrid Al–Bi2O3 particles (Bi2O3 nano-particles hybridized with Al using ball milling) have been synthesized, in this work, through powder metallurgy ...
Design and analysis of flexible joints for a robust 3d printed prosthetic hand
(
IEEE Computer Society
, 2019 , Conference Paper)
In war-affected regions in the world, limb loss is one of the leading injuries. The need for low-cost, low-maintenance prostheses arises. The rapid developments in 3D printing allows us to investigate robotic or prosthetic ...
