Topology preserving mappings are great tools for data visualization and inspection in large datasets. This research presents a combination of several topology preserving mapping models with some basic classifier ensemble and boosting techniques in order to increase the stability conditions and, as an extension, the classification capabilities of the former. A study and comparison of the perform...

This paper analyses the issue of innovation in developing countries with reference to local production systems populated by small enterprises. In these contexts innovation may result from imitation and from spillovers from foreign direct investments; however, the literature shows that these opportunities frequently find serious obstacles and are less fruitful than expected; for this reason we s...

We consider collaborative graph exploration with a set of k agents. All agents start at a common vertex of an initially unknown graph and need to collectively visit all other vertices. We assume agents are deterministic, vertices are distinguishable, moves are simultaneous, and we allow agents to communicate globally. For this setting, we give the first non-trivial lower bounds that bridge the ...

Engaging students in large system development projects is an important educational objective, since it exposes design and programming challenges that come to play only with scale. Alas, large scale system projects can be monstrously complex – to the extent of being infeasible in academic settings. We describe a set of principles and a framework that enable students to develop large-scale system...

The problem of sharing the cost of a common infrastructure among a set of strategic and cooperating players has been the subject of intensive research in recent years. However, most of these studies consider cooperative cost sharing games in an offline setting, i.e., the mechanism knows all players and their respective input data in advance. In this paper, we consider cooperative cost sharing g...

Several reports on national competitiveness already exists, but they are not satisfactory. This paper corrects the problems of the existing reports and suggests new methodologies of explaining national competitiveness. When comparing national competitiveness, nations should be grouped with regard to similarities in terms of economic scale and structure. For this purpose, this paper introduces 3...

Sustainable competitive advantage (CA) is a necessary requirement of a rational economic business organisation. Without this CA a business does not have a rational source for appropriating added value in the form of retained profit. Various management research papers have identified numerous factors that may create a source of competitive advantage. Other researchers have shown how industries h...

Given n potential oil locations, where each has oil at a certain depth, we seek good trade-offs between the number of oil sources found and the total amount of drilling performed. The cost of exploring a location is proportional to the depth to which it is drilled. The algorithm has no clue about the depths of the oil sources at the different locations or even if there are any. Abstraction of t...
