La representación tridimensional de grandes volúmenes de datos de terreno requiere un gran número de polígonos y de texturas, significando un problema la transmisión por red de los modelos. El enfoque multiresolución permite la transmisión progresiva, es decir, la transmisión…

This thesis attempts to gauge the strengths and limitations of the Java programming language in terms of its use in the production of multimedia compositions: in particular, the ways in which Java supports the creation of interactive, non-deterministic musical works.…

Java provides many attractive features such as platform independence, execution safety, garbage collection and object orientation. These features facilitate application development but are expensive to support; applications written in Java are often much slower than their counterparts written in C…

Nondeterminism makes distributed concurrent systems difficult to test, monitor and control. An execution of a message-passing system is nondeterministic when message races exist. Message race occurs when, e.g., multiple conflicting requests from different clients are competing to be executed within…

In this thesis, we present a cognitive theory of object-oriented metrics and an empirical study which has as objectives to formally test this theory while validating the metrics and to build a post-release fault proneness prediction model. The four cognitive…

Region-based memory management offers several important advantages over garbage-collected heap, including real-time performance, better data locality and efficient use of limited memory. The concept of regions was first introduced for a call-by-value functional language by Tofte and Talpin, and has…

The objective of this work is to supply one more contribution to the scientific community presenting techniques that will be used in distributed systems that need file replications in real time guaranteeing the permanent availability of the system. As the…
