TAMEx framework as an alternative for e-exam implementation in wireless network
One of significant change in learning process is exam implementation applying a computer-based test (e-exam) rather than paper-based test. Many institutions currently use wireless network with bring your own device (BYOD) policy for their e-exam…

The efficient interleaving of digital-video-broadcasting-satellite 2nd generations system
The DVB-S2 system is designed as a toolbox to permit the execution of
the satellite programs. Interleaver is an essential part of the DVB-S2
system. The current general block interleaver in DVB-S2 is not best, which leads to high BER and maybe not…

The influences of calcium fluoride and silica particles on improving color homogeneity of WLEDs
The LEDs lighting device with phosphor ingredient (pcLEDs) is among
the most common lighting methods in recent years and evaluated by chromatic uniformity and lighting capacity. Therefore, we introduce the phosphor particles that can improve the…

The options in remote phosphor structure for better white LEDs color quality
The WLEDs configuration with remote phosphor layers has higher
luminescent performance than WLEDs with dispense coating or conformal coating and is applied for many modern devices. However, managing the chromatic performance of lighting structure…

Transmission spectra of single ring coupled-waveguide resonator configuration by finite difference time domain method
Development of optical waveguide resonators have greatly expanded
and continues to grow since they have kinds potential applications such
as wavelength filtering, switching, coupling and multiplexing. One of
resonators, coupled waveguides, ring…

Viterbi optimization for crime detection and identification
In this paper, we introduce two types of hybridization. The first contribution is the hybridization between the Viterbi algorithm and Baum Welch in order to predict crime locations. While the second contribution considers the optimization based on…
