Amplifier

amps a necessary thing for your car? Well, they are if you want to have the best experience in your life. Some people may dismiss them as I want instead of the need, but that's really debatable. In fact, you might find that once you experience how amplifiers and subwoofers sound that they can be classified as a need. Just think of how much time you spend driving. Now, consider how often you drive without listening to the radio or to music. You probably listened to the radio or music most if not…

This is similar to a loudspeaker, it being simply an electronic sound amplifier. When you wear a behind the ear hearing aid, the microphone picks up sounds around you and turns them into an electric current. The amplifier then changes the size of the current to make it bigger. The loudspeaker then turns the boosted current back into a much louder sound. This louder sound continues to flow through…

John Stone Stone John Stone Stone, engineer and inventor, was born in Dover, Virginia on September 24, 1869.

Stone, father of John, Chief of Staff to the Khedive of Egypt spent over 12 years in Egypt building up an Egyptian army in the west. In late 1882, the British took over Egypt, and Stone resigned his position and returned to the United States where he was hired as chief…

The History of Future is my new project which its sole purpose is to bring you knowledge about the great things that we take for granted in our day by day life, present great geniuses which may or may not be known by the vast majority of people, weird and interesting things that had been done in the past and influenced the future and many other things. In the first article I will present you a great man, a man that invented the 20 century. The first person I will present you and probably the…

The Fins in this project are based on the Thresher shark. Its tail is shaped like a thresher, and the shark uses it as a weapon to stun its prey. Since this shark is an active predator, its tail should not only be used as a weapon, but also a great source of propulsion. In order to design and compare a fin to this extraordinary shark tail, a simple trapezoid was created to set a base model. Its dimensions are as follow: This fin is the base model designed to set the first data of propulsion, so…

Dame Mary Cartwright was one of the founders of the Theory of Chaos and a pioneer when it comes to women in mathematics. Because of her personality, she was described as a modest and did not receive all of the credit she deserved for her major contributions in the Theory of Chaos, or even for Cartwright Theorem. The mathematician was greatly affected by the First and Second World War, both in her education and in the research she did later in her life. The middle daughter of William Degby…

Language Diversity Language Diversity The diversity of languages is a fact of life There are about 6,500 different, mutually unintelligible languages, which belong to 250 large families. There is immense diversity in terms of contrastive sounds (phonemes) from a dozen to 100; in word order - Subject-Predicate, or Topic-Comment; some use inflections while others use particles. Linguistic diversity is related to the diversity of life—humans, animals, plants, and microbes. Every being communicates…

Rap and Hip-hop has an interesting origin story, has influenced by different genres of music, and created a new movement of freedom of speech. Dating back to the 60s and 70s in the South…

An AC current of 4 mA at 100 kHz was passed through the four outer electrodes (the top electrodes on the neck and the bottom electrodes on the abdomen), and Z0 was measured from the four inner electrodes. Biopac's EBI100C Electrical Bioimpedance Amplifier was used to record the impedance parameters. Finally, using Biopac's NIBP100A noninvasive blood pressure system, continual recordings of blood pressure were measured from the participant's radial artery of the nonpreferred arm. Four…

Sound can be found in every aspect of life, and the function of the ears allows one to process these noises and send them to the brain. The human ear has three main parts that work together in order to perform the necessary job: the outer ear, the middle ear, and the inner ear. The outer ear, the section that is visible to the human eye, allows sounds to enter through the ear canal. The eardrum separates the outer ear from the middle ear. When sound reached the middle ear, the ossicles, which…
