In a passive electronically scanned array (PESA), the microwave feed network in the back of the antenna is driven by a single high-power RF source (transmitter), sending its waves into phase shift modules (usually digitally-controlled), which, in turn, feed the transmitting/receiving elements. An AESA, instead, has an individual RF source for each of its many transmitting elements. This provides for a grace ...

The creation of an image from sound is done in three steps - producing a sound wave, receiving echos, and interpreting those echos. Ultrasound - Producing a sound wave. In medical ultrasonography, a sound wave is produced by creating short, strong pulses of sound from a phased array of piezoelectric transducers (usually a type of ceramic). The electrical wiring and transducers are encased in a probe. The electrical pulses vibrate the ceramic to create a series of sound pulses from each. The frequencies pre ...

Consider an emitter at unknown location (x,y,z) which we wish to locate. Consider also a multilateration system comprising four receiver sites at known locations: a central site, C, a left site, L, a right site, R and a fourth site, Q. The distances from the left, right and Qth side sites to the central site are defined as follows: Then the time difference of arrival of pulses at those three sites can then be shown by basic geometry to be as fol ...

Cochlear implant - The Older Patient. Cochlear implants are controversial from a quality of life perspective. The risk of surgery in the older patient must be weighed against the improvement in quality of life. As the devices improve, particularly the sound processor hardware and software, the benefit is judged to be worth the surgical risk particularly for the newly deaf elderly patient. [1] ...

There have been disputes whether ultrasound is safe. But since ultrasound is energy, there are questions such as, "What are the energy waves doing to my tissue?" There are some reports of low birth weight babies being born to mothers who had more than the recommended ultrasound examination. There may be side-effects of the following: Heat development: Local tissue absorb the ultrasound energy and increases the temperature of those tissues Bubble formation: Gasses, that are dissolved, come out of th ...

The modern Papal Inauguration, based through not exactly modelled on the form used for John Paul I, takes place during Mass (usually in the piazza outside Saint Peter's Basilica) and involves the formal bestowal of the pallium, the symbol of the pope's universal jurisdiction, on the newly elected pope by the senior Cardinal Deacon. Three popes have used the inauguration ceremony: Pope John Paul I, Pope Joh ...

Pope Benedict XVI was formally inaugurated as Supreme Pontiff on April 24, 2005. The day after his election, Benedict approved new procedures for the inauguration. The ceremony began with Benedict and the Cardinals kneeling at the tomb of Saint Peter — considered the first Pope — to give him homage. Benedict said, "I leave from where the Apostle arrived." The Pope and the Cardinals then processed out to Saint Peter's Square for the Inauguration Mass. < ...

The German philosopher, Gottfried Leibniz, came up with what is now called Leibniz's law (see Identity of indiscernibles) that may have some bearing on the question. Leibniz's law states: X is the same as Y if, and only if, X and Y have all the same properties and relations; thus, whatever is true of X is also true of Y, and vice-versa. Applying Leibniz's Law to the Ship of Theseus problem, S2 is the same as S1 if, and only if, S2 and S1 have all ...

One popular solution to the problem of the Ship of Theseus is to say that the meaning of "same" depends on what purpose the word is being used for. If, supposing it turns out that the original Ship of Theseus, S1, was actually stolen property, and the rightful owner demands its return, should the police give him S2 or S3? Instead of figuring out which ship, if either, is the "same", and then declaring that it should be returned, the pragmatic solution is to figure out which ship should be returned, and then declare that ...

Cochlear implants are usually recommended for individuals who have severe to profound sensorineural hearing loss and who do not benefit sufficiently from hearing aids. Individuals with auditory neuropathy may also benefit from cochlear implants. Cochlear implant centers determine implant candidacy on an individual basis and take into account a person's hearing history, cause of hearing loss, amount of residual hearing, speech recognition ability, health ...

The sense of being a chosen people occurs in both religious and nonreligious contexts. The Abolitionists, who were largely Christian, considered themselves chosen by God to bring freedom and equal rights to the slaves. Many slaveholders, another largely Christian group, saw themselves as chosen to keep and sell slaves. The Nazis considered the Aryan race to be superior, and believed it was their mission to dominate over all races they considered "inferior." Many religious and charitable organizations consider themselves to be chosen by God to care for the sick and the suffering. Man ...

Views of being a chosen people are sometimes connected with ethnocentrism. The idea of a chosen people can be used to justify or create cultural imperialism, racism, and xenophobia. However, the "chosen status," by definition is a humbling one, as it claims to carry greater responsibility and sacrifices than others. An example of this type of thought is exhibited in the Christian writing, Phillipians 2:5-8: "Your attitude should be the same that Christ Jesus had. Though he was God, he did not demand and cling to his rights as G ...

In Judaism, chosenness is the belief that the Jews are a people chosen to be in a covenant with God. The idea is not connected with tribal groupings as they are traditionally understood, as non-Jews are free to convert to Judaism. The Jewish idea of being chosen is first found in the Torah (five books of Moses) and is elaborated on in later books of the Hebrew Bible. This status carries both responsibilities and blessings as described in the Biblical covenants with God. Much is written about this topic in rabbinic literature. Judaism's teachings on being a chosen people are descr ...

Supersessionism is the belief of many Christians that Christians have replaced Israel as God's Chosen people. In this view, the Jews' chosenness found its ultimate fulfillment through the message of Jesus; Jews who remain non-Christian are no longer considered to be chosen, since they reject Jesus as the Messiah and son of God. Christians who ascribe to supersessionsism, cite the Bible verse John 14:6, attributed to Jesus: "I am the way, the truth, and the life, No one comes to the Father except through Me" as ev ...
