Fields of power seriesFinite fieldsThe continued fraction expansion for a quartic power series over the finite field was conjectured first in [W. Mills, D. Robbins, Continued fractions for certain algebraic power series, J. Number Theory 23 (1986) 388-404] and later in a more precise way ...
The recent global success story of Nordic noir, that encompasses products from film and television as well as literature, is often attributed to the great popularity of its places and characters. Many of the protagonists of some of the most popular TV-shows, for instance, are described as more...
In this post, I would like to explain how I have used Lambda to create a function to generate a Fibonacci series array.This example can also be used to understand how to create an array where the value of an element in the array depends on previous elements in the same array.Generating...
The binomial distribution is the sum of a series of multiple independent and identically distributed Bernoulli trials. In a Bernoulli trial, the experiment is said to be random and can only have two possible outcomes: success or failure. For instance, flipping a coin is considered to be aBernou...
With power series expansion techniques truncated power series of the control law can be obtained either as a power series of the state vector of the plant (Al'Brekht, 1961; Lukes, 1969; Garrard and Jordan, 1977), or as a power series of a scalar perturbation parameter (Garrard, 1972; ...
A series of factors can cause an economy and production to contract severely. In the case of the Great Depression, questionablemonetary policytook the blame. What Causes a Depression? An economic depression is a rolling disaster that begins with a decline in consumer confidence. There is, of co...
Intermittent behaviour of economic dynamics is studied by a nonlinear model of business cycles. Numerical simulations show that after an economic system evolves from order to chaos, the system keeps its memory before the transition and its time series alternates episodically between periods of low-leve...
However, these models have a major disadvantage as they do not allow forecasting the series with double seasonality and periods of non-integer values. The authors of this article, on the example of data on maximum energy demand, presented an application of one of the latest forecasting models ...
They are usually caused by a sudden rise or fall of part of the Earth's crust (地壳) under the ocean. Tsunamis often happen in oceans and they are most common in the Pacific. Normally a tsunamis includes a series of waves. Tsunamis can be very long-as much a, 100 kilometres-and be...
