I could see the heat waves swelling off of the sand near the water. The tall water grasses growing a few yards from the beach launch were turning brown and brittle from the constant sun (Woodford). It was supposed to be a hot summer‚ but even I didn’t think it was going to be this sweltering. This was my first job ever‚ and I was so excited to finally have something to do during summer break. I wished I could be out sailing with the other group‚ but right then I had to stay on the beach and do my

MODULATION TECHNIQUES 1.4.1 FREQUENCY SHIFT KEYING (FSK) Frequency shift keying is a frequency modulation in which the digital information is transmitted by discrete changes in frequency of the carrier signal. This technology is used for the communication system such as caller ID and emergency broadcasts [19]. The binary FSK is the simplest FSK. BFSK uses a pair of discrete frequencies to transmit binary information. The 1 and 0 is mentioned as mark frequency and space frequency. The other forms

transducer‚ impedance matching‚ tuning‚ equivalent circuit 1. Introduction Piezoelectric transducers are used for under water applications. As we know higher frequencies are more easily attenuated in water‚ so low frequency sound waves are used for under water mapping. Basically a transducer converts the electrical signal from power amplifier to acoustic signal‚ which propagates under water. A transducer is always operated at its resonance‚ where it has maximum amplitude of vibration

story. The tranquil diction used by Yukio Mishima in The Sound of Waves is very important to the calm island setting used in the story. The author’s smooth word choice complements the burgeoning love between Shinji and Hatsue‚ the two main characters. Mishima’s style also accentuates many instances of situational irony between the two young lovers and is only one of the many elements he uses in his composition. The Sound of Waves is a love story about Shinji and Hatsue and how they conquer the

Alpha waves are regular‚ have medium frequency‚ and occur while resting. Beta waves are irregular‚ have a low amplitude‚ and occur while attentive. In stage one of the sleep cycle‚ we experience Theta waves‚ which have similar frequencies and regularity to Alpha waves. Stage two also involves Theta waves‚ but may also have short bursts of Alpha and Beta waves called sleep spindles‚ or Delta waves called k complexes. These are the two shallowest sleep

Introduction Mistakenly called "tidal wave" the word tsunami is a Japanese word meaning‚ "harbor wave". A tsunami is a series of traveling ocean waves of extremely long length generated by disturbances associated primarily with earthquakes occurring below or near the ocean floor. Tsunamis are primarily the result of a vertical displacement of water and rank high on the scale of natural disasters. Since 1850‚ tsunamis have been responsible for the loss of over 440‚000 lives and billions of dollars

1.0 What Causes the Tides Tides are periodic rises and falls of large bodies of water. Tides are caused by the gravitational interaction between the earth and the moon. Tides are the cyclic rising and falling of earth’s ocean surface caused by the tidal forces of the moon and the sun acting on the earth . Tides cause changes in the depth of the sea and produce oscillating currents known as tidal streams‚ making prediction of tides important for coastal navigation. The strip of seashore
