Evaluation of a novel greenhouse design for reduced cooling loads during the hot season in subtropical regions
( Elsevier Ltd , 2019 , Article)Greenhouses provide an optimized growth environment for plants. However, providing this environment is energy intensive. In subtropical regions, most of this energy is to cater for the required cooling. The cooling demand ... -
Effect of fiber loading directions on the low cycle fatigue of intraply carbon-Kevlar reinforced epoxy hybrid composites
( Elsevier Ltd , 2019 , Article)Effect of fiber orientation on tensile and low cycle fatigue of intraply hybrid composites was investigated. In this work, intraply carbon/Kevlar fabric/epoxy hybrid composites were tested for static and cyclic loadings ... -
Transient response of porous FG nanoplates subjected to various pulse loads based on nonlocal stress-strain gradient theory
( Elsevier Ltd , 2019 , Article)Based on nonlocal strain gradient theory (NSGT), transient behavior of a porous functionally graded (FG) nanoplate due to various impulse loads has been studied. The porous nanoplate has evenly and unevenly distributed ... -
Highly improved AC conductivity of poly(aniline-o-fluoroaniline)
( Institute for Ionics , 2019 , Article)An improved frequency dependent AC-conductivity ng of poly(aniline-co-o-fluoroaniline)s (PA-co-o-FAs) has been recorded which are synthesized by in-situ copolymerization of aniline with o-fluoroaniline by oxidation of the ... -
Strain gradient based dynamic response analysis of heterogeneous cylindrical microshells with porosities under a moving load
( Institute of Physics Publishing , 2019 , Article)Forced vibration of a porous functionally graded (FG) cylindrical microshell due to a moving point load with constant velocity is studied for the first time. Through the thickness of microshell, there are even-type or ... -
Developing Polyaniline Filled Isoprene Composite Fibers by Electrospinning: Effect of Filler Concentration on the Morphology and Glass Transition
