Consider a large group of agents chasing a small group of moving targets. Assume each agent moves at constant speed toward the closest target. This paper studies the problem of controlling the agents indirectly by specifying the motion of the targets. In particular, it considers the problem of maintaining a minimum separation distance between each pair of agents, something that is impossible to...

This paper explains the idea to load source code into a Data Warehouse. First, separation of concerns is explained. Following, the motivation to load source code in a Data Warehouse is briefly presented. Afterwards, the multi-dimensionality of software is discussed. Also, a first model for software in a Data Warehouse is shown. Nearby, the challenge that multiple cubes will be needed in order t...

It has been demonstrated the product lines have introduced large improvements to quality, time to market and overall productivity. However, creating a successful product line is a highly complex and difficult task. There are still many technological barriers to overcome in effective product line development. The current industrial practice employs patterns, idioms and components to handle compl...
