Polynomials are widely used algebraic objects. They have the form of a sum of scaled powers of a variable.Monomials over RR Let RR be the set of real numbers. A monomial over RR in a single variable xx cons
In close-range photogrammetry the sensor is often close to the object of interest and is typically not nadir viewing, but rather looking horizontally, obliquely, or even upward in the case of mapping bridge engineering structure. This imagery is modeled mathematically in slightly different ways, hen...

The well-known Weierstrass theorem on the approximation of functions by polynomials asserts that a continuous function of several variables on a closed bounded set Ω can be uniformly approximated by a sequence of polynomials. Recently, powerful development, especially in connection with physical ...
To perform a partial fraction expansion, we need to extract an order 0 (length 1) FIR part via long division. Let and rewrite as a ratio of polynomials in : Then long division gives yielding or The delayed form of the partial fraction expansion is obtained by leaving the coefficients ...
The first concerns an old result due to Schur [10]. Given a polynomial f(x) ∈ Z[x], we say a prime p is a prime divisor of f if p|f(n) for some natural number n. An excellent introduction to the topic of prime divisors of polynomials can be found in [2]. Lemma 3. (...

The TSKFS consequents are frequently defined as linear functions (first-order polynomials): $$\begin{aligned} y^{\left( i\right) }\left( \mathbf {x}_{0}\right) =p_{0}^{\left( i\right) }+p_{1}^{\left( i\right) }x_{01}+p_{2}^{\left( i\right) }x_{02} +\cdots ...
Using this aproach, the 2nd-order bandpass of Figure 1 could be sufficiently specified by "a0 = a1 = a2 = b1 = 1", with all other coefficients equal to zero. Another way of writing a filter's transfer function is to factor the polynomials in the numerator and denominator so that they...
