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…

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.…

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.…

Los estudiantes de primer curso de Físicas de la Universidad de Murcia utilizan la herramienta de modelado Easy Java Simulations, Ejs, para realizar sus propias simulaciones, dicha herramienta permite desarrollar simulaciones con un aceptable pequeño esfuerzo informático, el Ejs produce…

Java programs are deployed in a bytecode format that is executed by a Java virtual machine (JVM). JVM performance is determined by several major components: execution engine, garbage collector, and threading system. The static compilation and optimization approach, such as…

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…

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.

In designing compiler analyses and optimisations, the choice of intermediate representation (IR) is a crucial one. Static Single Assignment (SSA) form in particular is an IR with interesting properties, enabling certain analyses and optimisations to be more easily implemented while…
