JOHNSON COOK CONSTITUTIVE MODELING FOR AUSTENITE METAL IN HOT FORMING PROCESS
Numerical computations have helped process engineers in designing the stamping process with minimal process defects. The constitutive modelling for hot stamping represents a complex relationship between stress, strain, strain rate and process temperature. The sheet thickness is 1.5 mm were prepar...
Role of the Whole Body Vibration Machine in the Prevention and Management of Osteoporosis in Old Age: A Systematic Review.
A literature search of related articles was carried out in electronic data sources. Initially, 276 randomised controlled trials related to the title were collected, after which 44 were selected using the keywords. Overlapping articles, articles with a study duration of less than six...
Intelligent Selective Spectrum Access in Cognitive Radio Networks
Wireless communication technology had enabled numerous services that had placed the current radio frequency bands at scarce. Thus, with the emerging of cognitive radio paradigm, the next generation network is determined to increase spectral efficiency in order to satisfy the wireless service...
Reinforcement of poly(vinyl alcohol) hydrogel with halloysite nanotubes as potential biomedical materials
This work reports the reinforcement of poly(vinyl alcohol) (PVA) hydrogel with halloysite nanotubes (HNT) as potential biomedical materials. The nanocomposite hydrogel was prepared using the facile and harmless process of freeze–thawing. Mechanical properties of the hydrogels were optimum at 2 wt...
Designing shape memory alloy linear actuators: A review
In numerous studies, it was emphasised that only a few of patented shape memory alloy applications are commercially successful due to material limitations combined with a lack of material and design knowledge and associated tools. This work further emphasises that these limitations may&...
Mechanical, thermal and instrumented impact properties of bamboo fabric-reinforced polypropylene composites
Many automotive companies are experimenting with natural fibres as a substitute for glass fibres in polymer composites, especially polypropylene (PP) based composites. PP composites reinforced by plain woven bamboo fabric have recently been widely investigated. Bamboo in woven fabric form embedde...
PERFORMANCE OF EGZrO2-EGFe2O3/HY AS PHOTOCATALYST AND ITS EFFICACY IN DECOLORIZATION OF DYE-CONTAMINANTS
The performance of electrogenerated metals supported on HY zeolite (EGZrO2-EGFe2O3/HY) was studied under sunlight irradiation for the decolorization of methylene blue (MB) and Congo red (CR) in aqueous solutions. The prepared photocatalysts were examined using X-ray diffraction (XRD), transmission...
Production of biogas through anaerobic digestion of Cabomba furcata in digester batch system
Biogas is produced from decomposition of organic waste such as sewage sludge, animal manure, and municipality solid wastes by microorganisms in anaerobic conditions. Biogas, which consist mainly of methane is a renewable energy source. It can be used for heating, power generation or...
