This work concerns the improvement of the software development environment for a research project using a custom-designed XML dialect. NestingXML has been designed to capture one kind of combinatorial problems in what concerns their input and output data. The dialect is used for storing problem and solution descriptions in a flexible way. In a project context, data formatted according to the dialect are imported into a Java API used for developing solvers and associated tools. The problem description is enriched with both preprocessing data and solution descriptions. We describe the NestingXML dialect and the Java API used in the project and illustrate their use in the problem-solving process. The resulting environment demonstrates increased flexibility in data representations and will become an easy integration medium for new team members.

In this dissertation, we present a characterization of the portuguese blogosphere based on a large set of portuguese blogs collected from multiple sources across a 5-year period.

The variant of the problem dealt with here considers only one big piece with fixed width and infinite length. Nesting problems have traditionally been tackled either by heuristic algorithms or, for rather small problems, by building mixed integer programming models.

We demonstrate that the Canine Pose Estimation (CPE) system can provide a reliable estimate for some poses and when coupled with effective wireless transmission over a mesh network, pose information can be made available to remote a handler
