The study evaluated the major constraints hampering the effective functioning of the Nigerian Agricultural Cooperative and Rural Development Bank (NACRDB) in Kogi State, Nigeria. Using the food crop farmers as a case study, a multi-stage random sampling technique was used to select three agricultural zone in Kogi State ( zone A, B, and C).Primary data were collected through the use of structure...

In calibrating the model, some of the parameter values are chosen based on data or recent empirical studies (summarized in Table 1 of the paper), and the remaining are obtained by finding the parameterization that best matches the steady state in the model to the average values in the American automobile industry over the 1994–2003 period. For the latter, we use the MPEC (Mathematical Programmi...

Unit quaternion is an ideal parameterization for joint rotations. However, due to the complexity of the geometry of S group, it’s hard to specify meaningful joint constraints with unit quaternion. In this paper, we have proposed an effective and accurate method to specify the rotation limits for joints parameterized with the unit quaternion. Joint constrains constructed with our method are adeq...

The two central problems in morphology are word formation and morphological alternations. The study of word formation is about the principles that govern the combinations of stems, affixes, and other types of morphemes. The problem of morphological alternations arises from the fact that a morpheme may have alternate realizations depending on its phonological environment and the composition of t...

We pursue the perspective of Reiter that in the situation calculus one can formalize primitive, determinate actions with axioms which, among others, include two disjoint sets: a set of successor state axioms and a set of action precondition axioms. We posed ourselves the problem of automatically generating successor state axioms, given only a set of e ect axioms and a set of state constraints. ...

The evaluation of constraints needs in many cases that a large portion of the database to be accessed. This makes the process of integrity checking very di cult to implement e ciently. Thus nding methods to improve the evaluation of integrity constraints is an important area of research in the eld of database integrity. Most of these methods are based on simpli cation principles. One of these m...

This paper is concerned with some feasibility issues in mathematical programs with equilibrium constraints (MPECs) where additional joint constraints are present that must be satis ed by the state and design variables of the problems. We introduce su cient conditions that guarantee the feasibility of these MPECs. It turns out that these conditions also guarantee the feasibility of the quadratic...
