Effect of expanded graphite on the phase change materials of high density polyethylene/wax blends
(
Elsevier
, 2015 , Article)
Phase change materials fabricated from high density polyethylene (HDPE) blended with 40 or 50 wt% commercial wax (melting point of 43.08�C) and up to 15 wt% expanded graphite (EG) were studied. Techniques including scanning ...
Graphene and graphitic derivative filled polymer composites as potential sensors
(
Royal Society of Chemistry
, 2015 , Article)
Graphite and numerous graphitic-derived micro- and nano-particles have gained importance in current materials science research. These two-dimensional sheets of sp2-hybridized carbon atoms remarkably influence the properties ...
Nanomechanical properties of plasma treated polylactic acid
(
Maney Publishing
, 2015 , Article)
In this work, a radio frequency discharged plasma generated in air atmosphere by pressure has been used to modify polylactic acid (PLA) surface. The results were evaluated through nanoindentation testing. Contact angle ...
Human gait recognition with cane assistive device using quadratic time-frequency distributions
(
Institution of Engineering and Technology
, 2015 , Article)
In this study, the authors consider the problem of human gait recognition in the presence of a walking cane using radars. Quadratic time-frequency distributions are used to provide the local signal behaviour over frequency ...
Time-frequency features for pattern recognition using high-resolution TFDs: A tutorial review
(
Elsevier Inc.
, 2015 , Article)
This paper presents a tutorial review of recent advances in the field of time-frequency (t, f) signal processing with focus on exploiting (t, f) image feature information using pattern recognition techniques for detection ...
Micro-Doppler characteristics of elderly gait patterns with walking AIDS
(
SPIE
, 2015 , Conference Paper)
In this paper, we analyze the micro-Doppler signatures of elderly gait patterns in the presence of walking AIDS using radars. The signatures are based on real data experiments conducted in a laboratory environment using ...
Free-volume correlation with mechanical and dielectric properties of natural rubber/multi walled carbon nanotubes composites
(
Elsevier Ltd
, 2015 , Article)
Abstract The microstructure, mechanical strength, dielectric properties, Doppler broadening measurements and positron life time studies of the composites containing multi walled carbon nanotubes (MWCNTs) and natural rubber ...
Enhanced morphology and mechanical characteristics of clay/styrene butadiene rubber nanocomposites
(
Elsevier Ltd
, 2015 , Article)
Achieving complete exfoliation of clay in their polymer nanocomposite is a matter of interest as it can significantly affect the material properties. Herein, an efficient way of enhancing the interlayer spaces of organically ...
Thermal properties of smart microencapsulated paraffin/plaster composites for the thermal regulation of buildings
(
Elsevier Ltd
, 2015 , Article)
Smart plaster composites were manufactured by mixing plaster with different amounts of Micronal? DS5001X microcapsules containing a paraffin mixture with a melting point of 26 �C to develop new construction materials with ...
