AI FOR COGNINITIVE RADIO Abstract: Cognitive radio (CR) is an enabling technology for numerous new capabilities such as spectrum access‚ spectrum sensing‚ spectrum decision‚ spectrum sharing and self organizing networks. This paper reviews several AI techniques used in cognitive radios such as : artificial neural network (ANN)‚ hidden Markov models (HMMs)‚ metahueristic algorithms‚ these techniques are proposed to provide the cognition capability in a cognitive engine. The modern

Seismic waves‚ which are waves of energy that travel through the earth‚ and are a result of an earthquake‚ explosion‚ or a volcano that imparts low-frequency acoustic energy. There are two types of seismic waves‚ Body waves and surface waves. Body waves travel through the interior of the earth. Surface waves travel along the earth’s surface and through water. Seismic wave fields are measured by a seismograph‚ geophone‚ hydrophone or accelerometer. These are used to measure earthquakes. When

Ocean Waves A wave is a periodic disturbance in space and time‚ possibly transferring energy to or through a space-time region. Have you ever ridden a wave in the ocean? Ocean waves travel on the surface of the water. You can see them and you can feel them. As you swim through the water‚ you can even make your own waves. The winds cause waves on the surface of the ocean (and on lakes). The wind transfers some of its energy to the water‚ through friction between the air molecules and the water molecules

WAVE ENERGY Chapter 2: Energy Technology 2.1 Source of Wave Energy Ocean waves are caused by the wind as it blows across the open expanse of water‚ the gravitational pull from the sun and moon‚ and changes in atmospheric pressure‚ earthquakes etc. Waves created by the wind are the most common waves and the waves relevant for most wave energy technology. Wave energy conversion takes advantage of the ocean waves caused primarily by the interaction of winds with the ocean surface. Wave energy is
