Tom Friedman (artist)Tom Friedman (born 1965) is an American conceptual sculptor. He was born in St. Louis, Missouri and received a BFA in graphic illustration from Washington University in St. Louis (1988) and an MFA in sculpture from the University of Illinois at Chicago (1990.). As a conceptual artist he works in diverse media including sculpture, painting, drawing, video, and installation. For over twenty years, Friedman has been investigating the viewer/object relationship, and "the space in between.
OverfittingIn mathematical modeling, overfitting is "the production of an analysis that corresponds too closely or exactly to a particular set of data, and may therefore fail to fit to additional data or predict future observations reliably". An overfitted model is a mathematical model that contains more parameters than can be justified by the data. In a mathematical sense, these parameters represent the degree of a polynomial. The essence of overfitting is to have unknowingly extracted some of the residual variation (i.
Ryszard KrynickiRyszard Krynicki (Polish: 'ryszard-kry'ńickJi; born 28 June 1943) is a Polish poet and translator, member of the Polish "New Wave" Movement. He is regarded as one of the most prominent post-war contemporary Polish poets. In 2015, he was awarded the Zbigniew Herbert International Literary Award as a recognition for his poetry works. He was born on 28 June 1943 in St. Valentin, Austria. After World War II, he moved to Poland, where he graduated from Marie Curie High School No. 2 in Gorzów Wielkopolski.
Martingale (probability theory)In probability theory, a martingale is a sequence of random variables (i.e., a stochastic process) for which, at a particular time, the conditional expectation of the next value in the sequence is equal to the present value, regardless of all prior values. Originally, martingale referred to a class of betting strategies that was popular in 18th-century France. The simplest of these strategies was designed for a game in which the gambler wins their stake if a coin comes up heads and loses it if the coin comes up tails.
Fritz the CatFritz the Cat is a comic strip created by Robert Crumb. Set in a "supercity" of anthropomorphic animals, it focused on Fritz, a tabby cat who frequently went on wild adventures that sometimes involved sexual escapades. Crumb began drawing the character in homemade comic books as a child. Fritz became one of his best-known characters, thanks largely to the motion picture adaptation by Ralph Bakshi.
Doob's martingale convergence theoremsIn mathematics specifically, in the theory of stochastic processes Doob's martingale convergence theorems are a collection of results on the limits of supermartingales, named after the American mathematician Joseph L. Doob. Informally, the martingale convergence theorem typically refers to the result that any supermartingale satisfying a certain boundedness condition must converge.
Frank PiatekFrank Piatek (born 1944) is an American artist, known for abstract, illusionistic paintings of tubular forms and three-dimensional works exploring spirituality, cultural memory and the creative process. Piatek emerged in the mid-1960s, among a group of Chicago artists exploring various types of organic abstraction that shared qualities with the Chicago Imagists; his work, however relies more on suggestion than expressionistic representation.
Nicholas SparksNicholas Charles Sparks (born December 31, 1965) is an American romance novelist, screenwriter, and film producer. He has published twenty-three novels, all New York Times bestsellers, and two works of non-fiction, with over 115 million copies sold worldwide in more than 50 languages. Among his works are The Notebook, A Walk to Remember, and Message in a Bottle which, along with eight other books, have been adapted as feature films. Sparks lives in North Carolina, where many of his novels are set.
2019 Maharashtra Legislative Assembly electionThe 2019 Maharashtra Legislative Assembly election was held on 21 October 2019 to elect all 288 members of the state's Legislative Assembly. After a 61.4% turnout in the election, the ruling National Democratic Alliance (NDA) of the Bharatiya Janata Party (BJP) and Shiv Sena (SHS) won a majority. Following differences over the government formation, the alliance was dissolved, precipitating a political crisis. Since a council of ministers had not been formed after no party could manage to form the government, President's rule was imposed in the state.
Volt-ampereThe volt-ampere (SI symbol: VA, sometimes V⋅A or V A) is the unit of measurement for apparent power in an electrical circuit. It is the product of the root mean square voltage (in volts) and the root mean square current (in amperes). Volt-amperes are usually used for analyzing alternating current (AC) circuits. In direct current (DC) circuits, this product is equal to the real power, measured in watts. The volt-ampere is dimensionally equivalent to the watt: in SI units, 1 V⋅A = 1 W.
1998 Winter OlympicsThe 1998 Winter Olympics, officially known as the XVIII Olympic Winter Games and commonly known as Nagano 1998 (長野1998), was a winter multi-sport event held from 7 to 22 February 1998, mainly in Nagano, Japan, with some events taking place in the nearby mountain communities of Hakuba, Karuizawa, Nozawa Onsen, and Yamanouchi. The city of Nagano had previously been a candidate to host the 1940 Winter Olympics (which were later cancelled), as well as the 1972 Winter Olympics, but had been eliminated at the national level by Sapporo on both occasions.
Static VAR compensatorA static VAR compensator (SVC) is a set of electrical devices for providing fast-acting reactive power on high-voltage electricity transmission networks. SVCs are part of the flexible AC transmission system device family, regulating voltage, power factor, harmonics and stabilizing the system. A static VAR compensator has no significant moving parts (other than internal switchgear). Prior to the invention of the SVC, power factor compensation was the preserve of large rotating machines such as synchronous condensers or switched capacitor banks.
