There is a large body of research that indicates the practice of cheating amongst students in the tertiary sector is widespread. Various studies have also attempted to determine r...
We present an automatic verification procedure based on RGSep that is suitable for reasoning about fine-grained concurrent heapmanipulating programs. The procedure computes a set o...
We present a simple method to formally prove termination of recursive functions by searching for lexicographic combinations of size measures. Despite its simplicity, the method tur...
This paper presents a practical approach to architecture-based design of computer based systems. The approach is discussed in relation to other existing of performing discovery, a...
