International Museum Day
International Museum Day (IMD) is an international day a celebration that held every year on or around 18 May, coordinated by the International Council of Museums (ICOM). The event highlights a specific theme that changes every year and that is at the heart of the international museum community's preoccupations.
Nyquist stability criterion
A Nyquist plot is a parametric plot of a frequency response used in automatic control and signal processing. The most common use of Nyquist plots is for assessing the stability of a system with feedback. In Cartesian coordinates, the real part of the transfer function is plotted on the X axis. The imaginary part is plotted on the Y axis. The frequency is swept as a parameter, resulting in a plot per frequency. The same plot can be described using polar coordinates, where gain of the transfer function is the radial coordinate, and the phase of the transfer function is the corresponding angular coordinate. The Nyquist plot is named after Harry Nyquist, a former engineer at Bell Laboratories.
Cartesian oval
In geometry, a Cartesian oval, named after René Descartes, is a plane curve, the set of points that have the same linear combination of distances from two fixed points.
Houston
The University of Houston System's annual impact on the Houston area's economy equates to that of a major corporation: $1.1 billion in new funds attracted annually to the Houston area, $3.13 billion in total economic benefit and 24,000 local jobs generated. This is in addition to the 12,500 new graduates the U.H. System produces every year who enter the workforce in Houston and throughout the state of Texas. These degree-holders tend to stay in Houston. After five years, 80.5% of graduates are still living and working in the region.
Anno Domini
The Anno Domini dating system was devised in 525 by Dionysius Exiguus to enumerate the years in his Easter table. His system was to replace the Diocletian era that had been used in an old Easter table because he did not wish to continue the memory of a tyrant who persecuted Christians. The last year of the old table, Diocletian 247, was immediately followed by the first year of his table, AD 532. When he devised his table, Julian calendar years were identified by naming the consuls who held office that year -- he himself stated that the ``present year ''was`` the consulship of Probus Junior'', which was 525 years ``since the incarnation of our Lord Jesus Christ ''. Thus Dionysius implied that Jesus' Incarnation occurred 525 years earlier, without stating the specific year during which his birth or conception occurred.`` However, nowhere in his exposition of his table does Dionysius relate his epoch to any other dating system, whether consulate, Olympiad, year of the world, or regnal year of Augustus; much less does he explain or justify the underlying date.''
List of presidents of the United States by age
The oldest living U.S. president is George H.W. Bush, born June 12, 1924 (age 93 years, 261 days). On November 25, 2017, he also became the longest - lived president, surpassing the lifespan of Gerald Ford, who died at the age of 93 years, 165 days. The second oldest living president, Jimmy Carter, has the distinction of having the longest post-presidency in U.S. history, currently at 37 years, 39 days. He surpassed the previous record, held by Herbert Hoover (31 years, 230 days) on September 7, 2012. The youngest living president is Barack Obama, born August 4, 1961 (age 56 years, 208 days).

Vacuum
Almost two thousand years after Plato, René Descartes also proposed a geometrically based alternative theory of atomism, without the problematic nothing–everything dichotomy of void and atom. Although Descartes agreed with the contemporary position, that a vacuum does not occur in nature, the success of his namesake coordinate system and more implicitly, the spatial–corporeal component of his metaphysics would come to define the philosophically modern notion of empty space as a quantified extension of volume. By the ancient definition however, directional information and magnitude were conceptually distinct. With the acquiescence of Cartesian mechanical philosophy to the "brute fact" of action at a distance, and at length, its successful reification by force fields and ever more sophisticated geometric structure, the anachronism of empty space widened until "a seething ferment" of quantum activity in the 20th century filled the vacuum with a virtual pleroma.
Cartesian coordinate system
The invention of Cartesian coordinates in the 17th century by René Descartes (Latinized name: Cartesius) revolutionized mathematics by providing the first systematic link between Euclidean geometry and algebra. Using the Cartesian coordinate system, geometric shapes (such as curves) can be described by Cartesian equations: algebraic equations involving the coordinates of the points lying on the shape. For example, a circle of radius 2, centered at the origin of the plane, may be described as the set of all points whose coordinates x and y satisfy the equation x + y = 4.
Model year
In the United States, automobile model - year sales traditionally begin with the fourth quarter of the preceding year. So model year refers to the sales model year; for example, vehicles sold during the period from October 1 to September 30 of the following year belong to a single model year. In addition, the launch of the new model - year has long been coordinated to the launch of the traditional new television season (as defined by A.C. Nielsen) in late September, because of the heavy dependence between television to offer products from automakers to advertise, and the car companies to launch their new models at a high - profile time of year.
Tuition fees in the United Kingdom
In England, tuition fee caps rose with the Higher Education Act 2004. Under the Act, universities in England could begin to charge variable fees of up to £3000 a year for students enrolling on courses as from the academic year of 2006 - 07 or later. This was also introduced in Northern Ireland in 2006 - 07 and introduced in Wales in 2007 - 08. In 2009 - 10 the cap rose to £3225 a year to take account of inflation. Following the Browne Review in 2010, the cap was controversially raised to £9,000 a year, sparking large student protests in London. A judicidal review against the raised fees failed in 2012, and so the new fee system came into use that September.
Selma Botman
Selma Botman is an American academic. Her post at the University of Maine System (UMS) Chancellor's Office focused on expanding the systems international education programs, recruiting foreign students, and coordinating overseas faculty exchanges.
Psychodynamics
Freud used the term psychodynamics to describe the processes of the mind as flows of psychological energy (libido) in an organically complex brain. The idea for this came from his first year adviser, Ernst von Brücke at the University of Vienna, who held the view that all living organisms, including humans, are basically energy - systems to which the principle of the conservation of energy applies. This principle states that ``the total amount of energy in any given physical system is always constant, that energy quanta can be changed but not annihilated, and that consequently when energy is moved from one part of the system, it must reappear in another part. ''This principle is at the very root of Freud's ideas, whereby libido, which is primarily seen as sexual energy, is transformed into other behaviours. However, it is now clear that the term energy in physics means something quite different from the term energy in relation to mental functioning.
Malaysia
The education system features a non-compulsory kindergarten education followed by six years of compulsory primary education, and five years of optional secondary education. Schools in the primary education system are divided into two categories: national primary schools, which teach in Malay, and vernacular schools, which teach in Chinese or Tamil. Secondary education is conducted for five years. In the final year of secondary education, students sit for the Malaysian Certificate of Education examination. Since the introduction of the matriculation programme in 1999, students who completed the 12-month programme in matriculation colleges can enroll in local universities. However, in the matriculation system, only 10 per cent of places are open to non-bumiputera students.
Computer
Computers have been used to coordinate information between multiple locations since the 1950s. The U.S. military's SAGE system was the first large-scale example of such a system, which led to a number of special-purpose commercial systems such as Sabre.

Materialism
The French cleric Pierre Gassendi (1592-1665) represented the materialist tradition in opposition to the attempts of René Descartes (1596-1650) to provide the natural sciences with dualist foundations. There followed the materialist and atheist abbé Jean Meslier (1664-1729), Julien Offray de La Mettrie, the German-French Paul-Henri Thiry Baron d'Holbach (1723-1789), the Encyclopedist Denis Diderot (1713-1784), and other French Enlightenment thinkers; as well as (in England) John "Walking" Stewart (1747-1822), whose insistence in seeing matter as endowed with a moral dimension had a major impact on the philosophical poetry of William Wordsworth (1770-1850).
Chesapeake Bay Retriever
A UK Kennel Club survey puts the median lifespan of the breed at 10.75 years (average 9.85). A US breed club survey puts the average lifespan at 9.4 years. 1 in 4 lived to 13 years or more while 1 in 5 do n't live past 5 years.
Chief Justice of India
The present CJI is Justice Dipak Misra and is the 45th CJI since January 1950, the year the Constitution came into effect and the supreme court came into being. He succeeded Justice Jagdish Singh Khehar on 28 August 2017 and will remain in office till 2 October 2018, the day he retires on turning 65 years in age.
Social Security (United States)
Originally the benefits received by retirees were not taxed as income. Beginning in tax year 1984, with the Reagan - era reforms to repair the system's projected insolvency, retirees with incomes over $25,000 (in the case of married persons filing separately who did not live with the spouse at any time during the year, and for persons filing as ``single ''), or with combined incomes over $32,000 (if married filing jointly) or, in certain cases, any income amount (if married filing separately from the spouse in a year in which the taxpayer lived with the spouse at any time) generally saw part of the retiree benefits subject to federal income tax. In 1984, the portion of the benefits potentially subject to tax was 50%. The Deficit Reduction Act of 1993 set the portion to 85%.
