In cognitive psychology, the telescoping effect (or telescoping bias) refers to the temporal displacement of an event whereby people perceive recent events as being more remote than they are and distant events as being more recent than they are.
 The former is known as backward telescoping or time expansion, and the latter as is known as forward telescoping.
 Three years is approximately the time frame in which events switch from being displaced backward in time to forward in time, with events occurring three years in the past being equally likely to be reported with forward telescoping bias as with backward telescoping bias.
 Although telescoping occurs in both the forward and backward directions, in general the effect is to increase the number of events reported too recently.
 This net effect in the forward direction is because of forces that impair memory, such as lack of salience, also impair time perception.
 Telescoping leads to an over reporting of the frequency of events.
 This over reporting is because participants include events beyond the period, either events that are too recent for the target time period (backward telescoping) or events that are too old for the target time period (forward telescoping).
An integrating ADC is a type of analog-to-digital converter that converts an unknown input voltage into a digital representation through the use of an integrator.
 In its basic implementation, the dual-slope converter, the unknown input voltage is applied to the input of the integrator and allowed to ramp for a fixed time period (the run-up period).
 Then a known reference voltage of opposite polarity is applied to the integrator and is allowed to ramp until the integrator output returns to zero (the run-down period).
 The input voltage is computed as a function of the reference voltage, the constant run-up time period, and the measured run-down time period.
 The run-down time measurement is usually made in units of the converter's clock, so longer integration times allow for higher resolutions.
 Likewise, the speed of the converter can be improved by sacrificing resolution.
Johan Martin Quist or Qvist (1755–1818) was a Danish architect who made a significant contribution to the city of Copenhagen.
 Together with those of Andreas Hallander, his classically styled buildings form part of the legacy of 19th-century Danish Golden Age architects who reconstructed areas of the old town which had been destroyed by fire.
Andreas Hallander (1755–1828) was a Danish master carpenter and architect who made a significant contribution to the city of Copenhagen.
 Together with the buildings of Johan Martin Quist, his classically styled apartment houses form part of the legacy of 19th-century Danish Golden Age architects who reconstructed areas of the old town which had been destroyed in the Great Fire of 1795.
Jørgen Henrich Rawert was a (16 August 1751 – 14 July 1823) was a Danish architect.
 He created the masterplan for the rebuilding of Copenhagen after the Great Fire of 1795 in his capacity of city architect and was also involved in many building projects, mostly of townhouses, often collaborating with Andreas Hallander.
The Danish Golden Age (Danish: "Den danske guldalder" ) covers a period of exceptional creative production in Denmark, especially during the first half of the 19th century.
 Although Copenhagen had suffered from fires, bombardment and national bankruptcy, the arts took on a new period of creativity catalysed by Romanticism from Germany.
 The period is probably most commonly associated with the Golden Age of Danish Painting from 1800 to around 1850 which encompasses the work of Christoffer Wilhelm Eckersberg and his students, including Wilhelm Bendz, Christen Købke, Martinus Rørbye, Constantin Hansen and Wilhelm Marstrand, as well as the sculpture of Bertel Thorvaldsen.
The list of Florida hurricanes from 1950 to 1974 encompasses 85 Atlantic tropical or subtropical cyclones that affected the U.S. state of Florida.
 Collectively, tropical cyclones in Florida during the time period resulted in about $7.04 billion (2017 USD) in damage, primarily from Hurricanes Donna and Dora.
 Additionally, tropical cyclones in Florida were directly responsible for 93 fatalities during the period, as well as responsible for 23 indirect deaths.
 Several tropical cyclones produced over 20 inches (500 mm) of rainfall in the state, including Hurricane Easy which is the highest total during the time period.
 The 1969 season was the year with the most tropical cyclones affecting the state, with a total of 8 systems.
 The 1954 and 1967 seasons were the only years during the time period in which a storm did not affect the state.
The list of Florida hurricanes from 1900 to 1949 encompasses 108 Atlantic tropical cyclones that affected the U.S. state of Florida.
 Collectively, tropical cyclones in Florida during the time period resulted in about $4 billion (2008 USD) in damage.
 Additionally, tropical cyclones in Florida were directly responsible for about 3,550 fatalities during the time period, most of which from the 1928 Okeechobee Hurricane.
 The 1947 season was the year with the most tropical cyclones affecting the state, with a total of 6 systems.
 The 1905, 1908, 1913, 1927, 1931, 1942, and 1943 seasons were the only years during the time period in which a storm did not affect the Floridian coasts.
Andreas Johannes Kirkerup (9 June 1749 – 22 October 1810) was a Danish architect and master builder, one of the most significant pupils of Caspar Frederik Harsdorff.
 Together with architects such as Andreas Hallander and Johan Martin Quist, he played a major role in the rebuilding of Copenhagen after the Great Fire of 1795.
Human population change is the difference between the size of the population from the beginning to the end of a certain time period.
 In other words, population change refers to change in the number of people during a specific time period.
 As a whole,the world population has not been stable; it has increased manifold.
 Due to this constant changing population, the subject of demographics, the statistics of how many people there are in a given population, was created.
 Demography can also be defined as the study of populations, and the factors that cause the most amount of population growth or decline.
 The main measurements of demography include: birth rates, death rates, sex ratios, life expectancy, and migration rates.
 All of these measures are found by a series of surveys and censuses conducted over a time period in order to compare how the population is changing.
 Other ways to measure population demographics include the use of historical maps, aerial photographs, and census statistics.
 One of the reasons why demographers use statistics about population change is because of the social and demographic transformations that the world experiences; significant challenges for the government and businesses will take effect depending on the degree of the population change.
