This paper discusses an Interval Quadratic Programming (IQP) problem, where the constraints coefficients and the right-hand sides are represented by interval data. First, the focus is on a common method for solving Interval Linear Programming problem. Then the idea is extended to the IQP problem. Based on this method each IQP problem is reduced to two classical Quadratic Programming (QP) proble...

two experiments were conducted to determine threonine (thr) requirements of two commercial strains, ross 308 and cobb 500, based on standardized ileal digestibility from 15 to 28d of age. basal diet consisted of wheat, triticale, and corn gluten meal was formulated according to quick chick (2006) to be adequate in all nutrients except for thr. incremental levels of supplemental thr were added t...

The number of simultaneous solutions of a quadratic and a linear congruence does not seem to be discussed in the literature, yet a knowledge of the invariants necessary to specify this number should lead to an arithmetical classification of the form-pairs involved. This preliminary investigation is confined to congruences with modulus odd and prime to the g.c.d.'s of the two sets of coefficient...
