A Novel Ultra-Wideband Monopole Antenna with Band-Stop Characteristic
(Scientific Research Publishing, 2011-10)
In this letter, a simple monopole antenna with variable band-notched characteristic for ultra wide band (UWB) function is proposed. Two L-shaped quarter-waveguide resonators coupled to the ground plane with two shorting ...
An Efficient Method to Reduce the Numerical Dispersion in the HIE-FDTD Scheme
(Scientific Research Publishing, 2011-01)
A parameter optimized approach for reducing the numerical dispersion of the 3-D hybrid implicit-explicit finite-difference time-domain (HIE-FDTD) is presented in this letter. By adding a parameter into the HIE-FDTD formulas, ...
Inhomogeneous Perforated Reflect-Array Antennas
(Scientific Research Publishing, 2011-03)
A new reflect-array antenna structure is proposed. This structure utilizes a perforated substrate as a reflecting surface with the lattice of different holes. The effective electric permittivity of the dielectric substrate ...
Performance Study of Multi-Path in VANETs and Their Impact on Routing Protocols
(Scientific Research Publishing, 2011-07)
Modeling complicated vehicular traffic behavior and analyzing effects on the communication performance of routing protocols taken by environmental factors have been a challenging task for the past several years. In this ...
Supply and Demand Oriented Energy Management in the Internet of Things
(Scientific Research Publishing, 2016-01)
The Internet of Things (IoT) is emerging as an attractive paradigm involving physical perceptions, cyber interactions, social correlations and even cognitive thinking through a cyber-physical-social-thinking hyperspace. ...
Learning Based Falling Detection Using Multiple Doppler Sensors
(Scientific Research Publishing, 2013-04)
Automated falling detection is one of the important tasks in this ageing society. Such systems are supposed to have little interference on daily life. Doppler sensors have come to the front as useful devices to detect human ...
Improving Bandwidth of Yagi-Uda Arrays
(Scientific Research Publishing, 2012-01)
A novel approach for improving antenna bandwidth is described using a 6-element Yagi-Uda array as an example. The new approach applies Central Force Optimization, a deterministic metaheuristic, and Variable Z0 technology, ...
Electronic Commerce Technology Adoption at the Scientific and Industrial Research and Development Centre
(Scientific Research Publishing, 2013-06)
This paper focuses on the level of adoption of E-Commerce Technology at the Scientific and Industrial Research and Development Centre (SIRDC), a Zimbabwean organization established by an act of parliament, with a mandate ...
Prospects for Mobile Health in Pakistan and Other Developing Countries
(Scientific Research Publishing, 2013-05)
akistan is a developing country with more than half of its population located in rural areas. These areas neither have sufficient health care facilities nor a strong infrastructure that can address the health needs of the ...
Cloud Computing Solution and Services for RFID Based Supply Chain Management
(Scientific Research Publishing, 2013-09)
Deploying and Implementing RFID Systems for tracking and controlling products in supply chain management is not affordable for small and midsized companies due to its complexity, cost, and difficulties pertaining data ...
