Reflection loss performance of hexagonal base pyramid microwave absorber using different agricultural waste material
(Institute of Electrical and Electronics Engineers (IEEE), 2010-11-08)
Hexagonal base pyramid microwave absorber is the new design of microwave absorber. In this work, two sub-shapes are considered to compare it reflection loss performance. The shapes are hexagonal and truncated hexagonal ...
Nanoherbals in Human Healthcare: A Proposed Research and Development Roadmap II
(Universitas Gadjah Mada, 2012)
Bioactive secondary metabolites derived from herbs are examined for their suitability of conversion into nanoforms having flexible morphological controls, surface stabilizations and surface functionalization. This can lead ...
Lightweight Heat Resistant Geopolymer-based Materials Synthesized from Red Mud and Rice Husk Ash Using Sodium Silicate Solution as Alkaline Activator
(EDP Sciences, 2017)
Geopolymer is an inorganic polymer composite with potentials to replace Ordinary Portland Cement (OPC)-based materials in the future because of its lower energy consumption, minimal CO2 emissions and lower production cost ...
Assessing Antimicrobial Activity of Aloe Vera against Colletrotrichum Capsici and Bacillus Subtilis
(Universiti Malaysia Perlis (UniMAP), 2018)
Nowadays, overuse of chemical fungicide has a side effect which is harmful to human, cause
environmental problem and destroys the antagonist microorganisms. Therefore, it is
important to develop natural fungicide and ...
A novel 2.45GHz switchable beam textile antenna (SBTA) for outdoor wireless body area network (WBAN) applications
(EMW Publishing, 2013)
A novel switchable beam textile antenna (SBTA) for wireless body area network (WBAN) applications is proposed. The SBTA is centrally-fed by a coaxial probe and the power distributed over four circular radiating elements. ...

Optimized SFCW radar sensor aiming at fall detection in a real room environment
(Institute of Electrical and Electronics Engineers (IEEE), 2013-01)
An optimization of a Stepped-Frequency Continuous Wave (SFCW) radar for contactless fall detection and tag-less localization is presented and discussed. Wideband antennas with different topologies are investigated to solve ...
Microwave wedge absorber design using rice husk - An evaluation on placement variation
(Institute of Electrical and Electronics Engineers (IEEE), 2010-04-12)
Placement variation is one example of parameters
that critically affects the performance of RF absorbers. In this
work, four designed variation patterns - W, X, Y, and Z were
discussed to compare the reflectivity (Sll) ...
