Purpose The paucity of empirical evidence on the limitations industrial attachment programme technical universities for enhancing students' human capital in Africa tends to thwart concrete policy options. Design/methodology/approach study used convergent mixed methods including 594 surveys, two focus groups and in-depth interviews assess accentuate research gap this study. Findings Evidence con...

This paper analyzes the capacity-planning process of database management systems focusing the theoretical decision models that considers the variables constraints that could be taken slightly and other variable constraints that are indispensable during upgrade. In order to proceed with the aforementioned, we assume that capacity planning decision, which considers the general corporate, technica...

Technical systems are prevalent in many areas of our society. Nowadays they often include a considerable amount of software. Identification and avoidance of technical risks is of major importance in the development of these softwareintensive technical systems. A powerful analysis technique in the development process for technical systems is the Failure Mode and Effects Analysis (FMEA). This tec...

The role of XML in data exchange is evolving from one of merely conveying the structure of data to one that also conveys its semantics. In particular, several proposals for key and foreign key constraints have recently appeared, and aspects of these proposals have been adopted within XMLSchema. Although several validators for XMLSchema appear to check for keys, relatively little attention has b...

The problem of finding a next best viewpoint for 3D modeling or scene mapping has been explored in computer vision over the last decade. This paper tackles a similar problem, but with different characteristics, and proposes a method for dynamic best viewpoint recovery of a target point while avoiding possible occlusions. Since the environment can change, the method has to iteratively find the n...

For a long time, the bilevel programming problem has essentially been considered as a special case of mathematical programs with equilibrium constraints (MPECs), in particular when the so-called KKT reformulation is in question. Recently though, this widespread believe was shown to be false in general. In this paper, other aspects of the difference between both problems are revealed as we consi...

This paper addresses two second-best toll pricing problems, one with fixed and the other with elastic travel demands, as mathematical programs with equilibrium constraints. Several equivalent nonlinear programming formulations for the two problems are discussed. One formulation leads to properties that are of interest to transportation economists. Another produces an algorithm that is capable o...

This paper introduces six ways for handling a chain of lexicographic ordering constraint between the origins of identical orthotopes (e.g., rectangles, boxes, hyper-rectangles) subject to the fact that they should not pairwise overlap. While the first two ways deal with the integration of a chain of lexicographic ordering constraint within a generic geometric constraint kernel, the four latter ...

Symmetry is an important feature of many constraint programs. We show that any problem symmetry acting on a set of symmetry breaking constraints can be used to break symmetry. Different symmetries pick out different solutions in each symmetry class. This simple but powerful idea can be used in a number of different ways. We describe one application within model restarts, a search technique desi...
