Context and question: Antennas are characterized by a number of performance measures which a user would be concerned with in selecting or designing an antenna for a particular application. Chief among these relate to the directional characteristics (as depicted in the antenna's radiation pattern) and the resulting gain. Even in omnidirectional (or weakly directional) antennas, the gain can often be increased by concentrating more of its power in the horizontal directions, sacrificing power radiated toward the sky and ground. The antenna's power gain (or simply "gain") also takes into account the antenna's efficiency, and is often the primary figure of merit.
How could one deide what type of antenna is nedded for a project?
Answer: performance measures
Context and question: The history of the Ottoman Empire during World War I began with the Ottoman engagement in the Middle Eastern theatre. There were several important Ottoman victories in the early years of the war, such as the Battle of Gallipoli and the Siege of Kut. The Arab Revolt which began in 1916 turned the tide against the Ottomans on the Middle Eastern front, where they initially seemed to have the upper hand during the first two years of the war. The Armistice of Mudros was signed on 30 October 1918, and set the partition of the Ottoman Empire under the terms of the Treaty of Sevres. This treaty, as designed in the conference of London, allowed the Sultan to retain his position and title. The occupation of Constantinople and Izmir led to the establishment of a Turkish national movement, which won the Turkish War of Independence (191922) under the leadership of Mustafa Kemal (later given the surname "Ataturk"). The sultanate was abolished on 1 November 1922, and the last sultan, Mehmed VI (reigned 191822), left the country on 17 November 1922. The caliphate was abolished on 3 March 1924.
The Arab Revolt began in what year?
Answer: 1916
Context and question: Many historical sites exist throughout the city, including 59 properties listed on the National Register of Historic Places. Of these, nine are among the 60 U.S. National Historic Landmarks in Connecticut. The New Haven Green, one of the National Historic Landmarks, was formed in 1638, and is home to three 19th-century churches. Below one of the churches (referred to as the Center Church on-the-Green) lies a 17th-century crypt, which is open to visitors. Some of the more famous burials include the first wife of Benedict Arnold and the aunt and grandmother of President Rutherford B. Hayes; Hayes visited the crypt while President in 1880. The Old Campus of Yale University is located next to the Green, and includes Connecticut Hall, Yale's oldest building and a National Historic Landmark. The Hillhouse Avenue area, which is listed on the National Register of Historic Places and is also a part of Yale's campus, has been called a walkable museum, due to its 19th-century mansions and street scape; Charles Dickens is said to have called Hillhouse Avenue "the most beautiful street in America" when visiting the city in 1868.
What tourist spot can be found directly underneath the New Haven Green?
Answer:
a 17th-century crypt
