The measurements are based on what is called an Environmental Impact Quotient Field Use rating - a method of measuring the impacts of herbicide use based on toxicity, leaching, runoff, soil half-life and other factors of 100 pesticides approved for use by the U.
In the discrete-time case the definition of the transfer function is based on a non-commutative twisted polynomial ring, which is a special case of the skew polynomial ring and can be embedded into its quotient field by the Ore condition.
We also briefly sketch the construction of the quotient field of twisted polynomials.
where the entries of f and g are meromorphic functions, which we think of as elements of the quotient field of the ring of analytic functions, and x(t) [member of] [R.
The non-commutative ring can be embedded into its quotient field (or field of fractions) if the so-called Ore condition is satisfied.
The ring K[[delta]] can, therefore, be embedded into a non-commutative quotient field [17,18] by defining quotients as
