Behavior of CuPb12Sn6 Alloys subjected to Heat Treatments
(EDP Sciences, 2016-10)
The paper present the structural modifications induced by 3 heat treatments: homogenization, recrystallization and quenching, respecting the specific parameters of copper based alloys. The obtained modifications by heat ...
Site-specific evaluation of a MIMO channel capacity for multi-antenna mobile terminals in proximity to a human hand
(The European Association on Antennas and Propagation (EurAAP), 2011-04-10)
This paper presents a comprehensive evaluation on the Multiple-Input Multiple-Output (MIMO) channel capacity performance of a coupling element -based multi-antenna structures on a mobile terminal at the 2000 MHz Universal ...
Setup and results of pyramidal microwave absorbers using rice husks
(EMW Publishing, 2011)
Agricultural wastes are considered not useful and are commonly dumped or burned after crop harvesting. Rice husks from paddy (Oryza sativa) are example of agricultural wastes. Rice husks have been investigated as the ...
Ambiguity analysis of isolation - Based multi-antenna structures on mobile terminal
(Institute of Electrical and Electronics Engineering (IEEE), 2011-04-10)
This paper presents a comprehensive numerical study on the ambiguities for different isolation-based multi-antenna structures. The focus is on four-element planar inverted-F antennas (PIFA) array on a typical 100mm 40mm ...
A smart wearable textile array system for biomedical telemetry applications
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
A smart wearable textile array system (SWTAS) with direction of arrival (DoA) estimation and beamforming is proposed and developed for biomedical telemetry applications. This conformal system enables effective and continuous ...
Parametric studies of the pyramidal microwave absorber using rice husk
(Institute of Electrical and Electronics Engineers (IEEE), 2010)
Agriculture waste has potential to be used as an alternative material for the microwave absorber used in the anechoic chamber. Compared to the current materials used, such as polystyrene and polyurethane, agricultural waste ...
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 ...
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. ...
