Three-dimensional route maps, which depict a path from one location to another, can be powerful tools for visualizing and communicating directions. This thesis presents a client-server architecture for generating and displaying accurate, usable route maps between locations on MIT's campus.…

Acantholybas steinbaueri, a brachypterous new species, is described and illustrated from Java (Bali Island and Dammerman). The genus Acantholybas is redescribed, and a key to the four known species is provided.

I propose a technique that identifies program properties that may indicate errors. The technique generates machine learning models of run-time program properties known to expose faults, and applies these models to program properties of user-written code to classify and rank…

Over the past several years, the explosive growth of biological data generated by new high-throughput instruments has virtually begun to drown the biological community. There is no established infrastructure to deal with these data in a consistent and successful fashion.…

Model Driven Architecture (MDA) define un proceso de construcción de software basado en la producción y transformación de modelos. En Ingeniería de Software, refactorización es la técnica que reestructura código de una aplicación, alterando su estructura interna sin modificar su…

This paper presents a new approach to algorithm design and analysis that benefits from the OO characteristics of Java. It consists of first defining the inheritance structure of a collection of algorithms, at different levels of abstraction. Then, correctness proofs…

In this article we present a performance comparison of four symmetric block ciphers namely DES, Triple-DES, AES, and Blowfish. Performance evaluation based on CPU execution time is conducted under WinXP and Ubuntu /Linux version 8.10 operating system platforms. The study…
