Location Based Performance of WiMAX Network for QoS with Optimal Base Stations (BS)
(Scientific Research Publishing, 2011-07)
In this paper we are given concept of our WiMAX (Worldwide Interoperability for Microwave Access) network perfor-mance for QoS monitoring and optimization solution for BS (Base Station) with multimedia application. In the ...
A New Algorithm of Mobile Node Localization Based on RSSI
(Scientific Research Publishing, 2011-04)
Position mobile node coordinate is a key component to determine the accuracy and efficiency of positioning in wireless sensor networks. Flexible location algorithm admits to adjust the accuracy and time cost of positioning ...
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 ...
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 ...
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 ...
Insecticidal effect of plant extracts on two termite species
(published online, 2011-06)
The insecticidal contact activity of two desert plant extracts, Withania somnifera
and Solanum incanum (Tubiflora: Solanaceae) was tested against the workers
of the two species, Amitermes messinae and Microtermes najdensis ...
How to Identify Latent Systolic Dysfunction and Post Operative Risk in Patients with Mitral Incompetence and Normal Ejection Fraction?
(Scientific Research, 2011-12)
Purpose: To study the significance of impaired positive peak rate of left ventricular (LV) pressure development
(MR + dp/dt) and global systolic strain (GLPSS) values in patients presented with significant mitral
incompetence ...
Dengue Vaccines: Challenge and Confrontation
(Scientific Research, 2011-11)
Dengue has been recognized as one of the most important vector-borne human diseases. The disease is induced by
dengue virus infection resulting from the bite of an infected Aedes spp. mosquito after imbibing the tainted ...
