This paper describes the Context Awareness Framework developed for the HYDRA
Middleware Project. The HYDRA project aims to develop middleware to support intelligent …

We introduce ASketch, the first framework for sketching models in the Alloy language. The
Alloy Analyzer is a SAT-based constraint solver that allows users to create valuations for …

Generating likely invariants using dynamic analyses is becoming an increasingly effective
technique in software checking methodologies. This paper presents Deryaft, a novel …

Abstract Models of software systems, eg, designs, play an important role in the development
of reliable and dependable systems. However, writing correct designs is hard. What makes …

Dynamically allocated data structures pervade imperative and object-oriented programs.
Automated analysis and testing of such programs requires reasoning about their data …

Using a traditional debugging environment, a programmer has to manually trace the
execution of the program. On finding a corrupted program state, the programmer has to …

Bugs in code continue to pose a fundamental problem for software reliability and cause
expensive failures. The process of removing known bugs is termed debugging, which is a …

Formal modeling methods are becoming an important part of today's software development
process. The Alloy modeling language, which is one of the emerging modeling approaches …

The goal of this dissertation is to present new and improved techniques for fully automatic
verification of sequential and concurrent software libraries. In most cases, automatic …
