Enhance the performance of free space optical (FSO) communication due to atmospheric turbulence via the dual diffuser modulation (DDM)
(Trans Tech Publications, 2013-12)
This paper focus on mitigating the atmospheric turbulence effect in free space optical communication using dual diffuser modulation (DDM) technique. Phase screen diffuser located on transmitter create 'new' beam wave to ...
Comparison of single mode fiber and multimode fiber in deployment of SCM-OCDMA in local area network
(Trans Tech Publications, 2013-12)
The integration of heterogeneous technologies promotes ubiquity and mobility. Optical code division multiple access (OCDMA) may be deployed in conjunction to SCM to improve the spectral efficiency and enhance the data rate ...
Classification of driver drowsiness level using wireless EEG
(Przegląd Elektrotechniczny, 2013)
In this work, wireless Electroencephalogram (EEG) signals are used to classify the driver drowsiness levels (neutral, drowsy, high drowsy and sleep stage1) based on Discrete Wavelet Packet Transform (DWPT). Two statistical ...
Enhancement of algorithm and investigation of heat transfer through fins
(Praise Worthy Prize S.r.l., 2013-09)
Finite Element Method (FEM) and Differential Quadrature Method (DQM) are two very important numerical solution techniques to solve engineering and physical science problems. Usually elements are sub-divided uniformly in ...
A novel beam steering of hybrid switchable beam textile antenna
(Wiley Periodicals, Inc, 2013-08)
A novel hybrid switchable beam textile antenna (HSBTA) is proposed in this research. The HSBTA introduced by a coaxial probe technique to feed current flow to center of HSBTA and distribute the current to four circles of ...
Integration and deployment of IEEE 802.15.4 wireless sensor networks with a wireless mesh backhaul network
(AENSI Publisher All rights reserved, 2013-10)
This paper describes the deployment of a IEEE802.15.4 Wireless Sensor Network (WSN) in a campus network and integration with IEEE 802.11a/g Wireless Mesh Network (WMN) for the backhaul. The first problem discussed is the ...
Novel dual-band B-shaped printed monopole antenna for MIMO application
(INOE Publishing House, 2013-09)
Proposed antenna consists of B-shaped element which operates at dual-band frequencies (2.45 and 5.8 GHz). The antenna has been simulated using CST software and the prototype has been fabricated on FR4 substrate. The impedance ...
Bump height at low temperature analysis
(Trans Tech Publications (TTP), 2013)
The effects of chemical bath time in response to the bump height in electroless nickel immersion gold (ENIG) process was investigated. This paper presents the correlation between electroless process time, immersion gold ...
Proficient feature extraction strategy for performance enhancement of NN based early breast tumor detection
(Engg Journals Publications, 2013)
Ultra Wideband is one of the promising microwave imaging techniques for breast tumor prognosis. The basic principle of tumor detection depends on the dielectric properties discrepancies between healthy and tumorous tissue. ...
5mm × 5mm sized slug on high power LED stress and junction temperature analysis
(Trans Tech Publications (TTP), 2013)
Conventional incandescent lamps are being replaced by high power light emitting diode as a lighting source due to it ascendancy in terms of physical size, performance, output and lifetime. Nevertheless, the reliability and ...
