In this study, the effect of exposure to an 8 mT, 50 Hz extremely low-frequency electromagnetic field (ELF EMF) on memory consolidation adult male and female mice was studied. For purpose were randomly distributed among six groups ( n = 10 in each group). Using passive avoidance task, despite its natural tendency, mouse learns stay a small platform avoidant electric shock. Immediately after learning session, laboratory animals experimental placed sinusoidal EMF for 4 h. The second sham...

Abstract In the recent research of vehicular ad-hoc networks (VANETs), new practical goals are pursued. They provide real-world communications between vehicles and make them reliable easy-used. The VANETs have a fundamental role in reducing traffic accidents improving on roads. Authentication is critical security service, should be protected from breaking their personal information. Vehicles can traced investigated event an accident or liability arising out non-repudiation when vehicle faced...

Electromagnetic Fields (ELFs) may change biological organisms' behaviors and brain mechanisms. There are some findings about laboratory animal’s after exposure to electromagnetic fields but the changes in marine especially fish limited. In this mini review presentation of structure teleost fish, effects ELFs on expressed.

The spectrum sensing is a quite important part in cognitive radio. This paper discusses energy sensing, the common algorithm radio, as well some cooperative algorithms such AND, OR rule. Also modified periodogram methods have been investigated and simulated, moreover these various of detection signal simulated by specifying their advantages drawbacks. Our simulations shows that detector so easy to implement good when there no knowledge secondary users. Besides simulation about are...
