A Wireless Body Sensor Platform to Detect Progressive Deterioration in Musculoskeletal Systems
(Scientific Research Publishing, 2013-03)
Recent developments in technology have helped to reduce the physical size and weight of devices and opened up new opportunities for their application in delivering unobtrusive healthcare services. In particular, kinetic ...
Measurement of Rain Attenuation in Terahertz Wave Range
(Scientific Research Publishing, 2011-07)
ain attenuation at 355.2 GHz in the terahertz wave range was measured with our new 355.2 GHz measuring system under rainfall intensities up to 25 mm/hr. Rain attenuation coefficients were also calculated using four ...
P2P Model Based on Isolated Broadcast Domains
(Scientific Research Publishing, 2012-04)
Resource location is the most important issue for Peer-to-Peer (P2P) system and flooding is the fundamental mechanism for unstructured P2P systems. Redundant messages will exponential growth with flooding scope increasing ...
Bandwidth Enhancement and Size Reduction of Microstrip Patch Antenna by Magnetoinductive Waveguide Loading
(Scientific Research Publishing, 2011-01)
A planar magnetoinductive (MI) waveguide loaded rectangular microstrip patch antenna is presented and discussed. The MI waveguide consists of two planar metamaterial split squared ring resonators (SSRRs) placed in between ...
Design of an Acoustic Communication System Based on FHMA for Multiple Underwater Vehicles
(Scientific Research Publishing, 2010-07)
This paper designs an underwater acoustic communication system based on tamed spread spectrum and Frequency Hopping Multiple Access (FHMA) for multiple underwater vehicles. In this system, multiple underwater vehicles can ...
MoM Analysis and Design of a Compact Coaxial-to-Microstrip Directional Coupler
(Scientific Research Publishing, 2011-04)
In order to overcome the main drawbacks of coaxial, waveguide, and stripline couplers, the analysis and the design of a compact coaxial-to-microstrip directional coupler convenient for power and antenna control application, ...
Spiral Tuning Stub CPW-Fed UWB Slot Offset, Edge Cleft and Edge Slotted Antennas
(Scientific Research Publishing, 2011-07)
After the release of the unlicensed Ultra Wideband (UWB) spectrum 3.1 GHz to 10.6 GHz for the commercial purposes by the Federal Communications Commission (FCC), industries and academia pay much attention due to its ...
A Self-Similar Fractal Cantor Antenna for MICS Band Wireless Applications
(Scientific Research Publishing, 2011-04)
Low profile antenna in communication is a new methodology. Fractal geometry is a methodology through which size reduction is achieved. A Self-similar fractal antenna using multicantor technique is proposed and experimentally ...
Rain Attenuation at Terahertz
(Scientific Research Publishing, 2010-10)
Rain attenuation values were calculated using empirical raindrop-size distributions, which were, Marshall-Palmer (M-P), Best, Polyakova-Shifrin (P-S) and Weibull raindrop-size distributions, and also calculated using a ...
Interference Mitigation in Satellite Personal Communication Networks Using Adaptive Antenna Arrays and Filtering Technique
(Scientific Research Publishing, 2010-10)
We address the problem of interference as related to Satellite Personal Communication Networks (S-PCNs). Basic low Earth orbit (LEO) constellation is considered. The paper uses combined adaptive antenna arrays and adaptive ...
