Anders Lindstedt
Anders Lindstedt (27 June 1854 – 16 May 1939) was a Swedish mathematician, astronomer, and actuarial scientist, known for the Lindstedt-Poincaré method. Life and work Lindstedt was born in a small village in the district of Sundborns, Dalecarlia a province in central Sweden.Hvar 8 dag, 10:de Årg, No 11, 13 december 1908, sid. 162'.Memoir Anders Lindstedt 27 June 1854-16 May 1939, Journal of the Institute of Actuaries, 70 (1939) p. 269/ref> He obtained a PhD from the University of Lund aged 32 and was subsequently appointed as a lecturer in astronomy. He later went on to a position at the University of Dorpat (then belonging to Russia, now University of Tartu in Estonia) where he worked for around seven years on theoretical astronomy. He combined practical astronomy with an interest in theory, developing especially an interest in the three-body problem This work was to influence Poincaré whose work on the three-body problem led to the discovery that there can be or ...

Dalecarlia
Dalarna () is a '' landskap'' (historical province) in central Sweden. English exonyms for it are Dalecarlia () and the Dales. Dalarna adjoins Härjedalen, Hälsingland, Gästrikland, Västmanland and Värmland. It is also bordered by Norway in the west. The province's borders mostly coincide with the modern administrative Dalarna County ('' län''). The word "Dalarna" means "the dales" (valleys). The area is a holiday destination for Swedes from the south, who often travel there in the summer, drawn by its fishing lakes, campgrounds, and forests. Some Swedes own or rent a second home in Dalarna, where they are likely to have a vegetable garden and apple trees. In mid-June, midsummer celebrations and dances are held in many of the small villages and in the larger cities. Dalarna is a region full of historical associations, and both its products and its people have strong local characteristics. In the western district Lima, some people in villages speak a traditional dialect, Da ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Institute Of Technology
The KTH Royal Institute of Technology ( sv, Kungliga Tekniska högskolan, lit=Royal Institute of Technology), abbreviated KTH, is a public research university in Stockholm, Sweden. KTH conducts research and education in engineering and technology and is Sweden's largest technical university. Currently, KTH consists of five schools with four campuses in and around Stockholm. KTH was established in 1827 as the ''Teknologiska institutet (Institute of Technology)'' and had its roots in the ''Mekaniska skolan (School of Mechanics)'' that was established in 1798 in Stockholm. But the origin of KTH dates back to the predecessor of the ''Mekaniska skolan'', the ''Laboratorium mechanicum'', which was established in 1697 by the Swedish scientist and innovator Christopher Polhem. The Laboratorium mechanicum combined education technology, a laboratory, and an exhibition space for innovations. In 1877 KTH received its current name, Kungliga Tekniska högskolan (KTH Royal Institute of Technol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Swedish Welfare
Social welfare in Sweden is made up of several organizations and systems dealing with welfare. It is mostly funded by taxes, and executed by the public sector on all levels of government as well as private organizations. It can be separated into three parts falling under three different ministries. Social welfare is the responsibility of the Ministry of Health and Social Affairs. Education is the responsibility of the Ministry of Education and Research. The labour market is the responsibility of the Ministry of Employment. History The modern Swedish welfare system was preceded by the poor relief organized by the Church of Sweden. This was formalized in the Beggar Law of 1642, and became mandatory in the Civil Code of 1734, when each parish was required to have an almshouse. This system was changed with the Poor Law of 1847, when the first national poor care system separate from the church was organized: a mandatory public poor care relief fund financed by the public was ...

Probability
Probability is the branch of mathematics concerning numerical descriptions of how likely an Event (probability theory), event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty."Kendall's Advanced Theory of Statistics, Volume 1: Distribution Theory", Alan Stuart and Keith Ord, 6th Ed, (2009), .William Feller, ''An Introduction to Probability Theory and Its Applications'', (Vol 1), 3rd Ed, (1968), Wiley, . The higher the probability of an event, the more likely it is that the event will occur. A simple example is the tossing of a fair (unbiased) coin. Since the coin is fair, the two outcomes ("heads" and "tails") are both equally probable; the probability of "heads" equals the probability of "tails"; and since no other outcomes are possible, the probability of either "heads" or "tails" is 1/2 (which could also be written ...

Extrapolate
In mathematics, extrapolation is a type of estimation, beyond the original observation range, of the value of a variable on the basis of its relationship with another variable. It is similar to interpolation, which produces estimates between known observations, but extrapolation is subject to greater uncertainty and a higher risk of producing meaningless results. Extrapolation may also mean extension of a method, assuming similar methods will be applicable. Extrapolation may also apply to human experience to project, extend, or expand known experience into an area not known or previously experienced so as to arrive at a (usually conjectural) knowledge of the unknownExtrapolation entry at Merriam–Webster (e.g. a ...

Mortality
Mortality is the state of being mortal, or susceptible to death; the opposite of immortality. Mortality may also refer to: * Fish mortality, a parameter used in fisheries population dynamics to account for the loss of fish in a fish stock through death * ''Mortality'' (book), a 2012 collection of essays by Anglo-American writer Christopher Hitchens * Mortality (computability theory), a property of a Turing machine if it halts when run on any starting configuration * Mortality rate, a measure for the rate at which deaths occur in a given population * Mortality/differential attrition, an error in the internal validity of a scientific study See also * Case fatality rate, the proportion of deaths within a designated population of people with a medical condition * Cause of death * Fulminant * Mortality displacement, a (forward) temporal shift in the rate of mortality * Mortality rate or death rate * Mortality salience Mortality salience is the awareness by individuals that their de ...

Annuity (European Financial Arrangements)
Under European Union law, an annuity is a financial contract which provides an income stream in return for an initial payment with specific parameters. It is the opposite of a settlement funding. A Swiss annuity is not considered a European annuity for tax reasons. Immediate annuity An immediate annuity is an annuity for which the time between the contract date and the date of the first payment is not longer than the time interval between payments. A common use for an immediate annuity is to provide a pension to a retired person or persons. It is a financial contract which makes a series of payments with certain characteristics: * either level or fluctuating periodical payments * made annually, or at more frequent intervals * in advance or arrears * duration may be: **fixed (annuity certain) **during the lifetime or one or more persons, possibly reduced after death of one person **during the lifetime but not longer than a maximum number of years **during the lifetime but not ...

Life Table
In actuarial science and demography, a life table (also called a mortality table or actuarial table) is a table which shows, for each age, what the probability is that a person of that age will die before their next birthday ("probability of death"). In other words, it represents the survivorship of people from a certain population. They can also be explained as a long-term mathematical way to measure a population's longevity. Tables have been created by demographers including Graunt, Reed and Merrell, Keyfitz, and Greville. There are two types of life tables used in actuarial science. The period life table represents mortality rates during a specific time period of a certain population. A cohort life table, often referred to as a generation life table, is used to represent the overall mortality rates of a certain population's entire lifetime. They must have had to be born during the same specific time interval. A cohort life table is more frequently used because it is able to ma ...
