This thesis presents Dava, a Java bytecode to Java source code decompiler built on top of the Soot framework., The Java Virtual Machine Specification of valid bytecode is much less restrictive than the Java Language Specification of valid Java source…

Many compiler analyses and optimizations require precise information about the behaviour of pointers in order to be effective. Points-to analysis is a technique for computing this information that has been studied extensively over the last decade. Most of this research…

Effective dynamic virtual-machine optimization depends on quickly finding and optimizing frequently-executed code regions. Such regions are naturally represented with a trace-cache, a collection of long, frequently-executed sequences of instructions. An ideal trace-cache is small and captures the majority of the…

Stock option trading has been very active since options were invented. Option analysis is very useful in helping investors decide investing strategies and predict the trend of the future stock movements. In this thesis, basic theory about stock option trading…

This thesis presents a new algorithm to compute the probability that a state in a labeled Markov chain model satisfies an LTL specification. A solution to this problem was given by Courcoubetis & Yannakakis in 1995, but unlike their solution…

Program tracing is a common technique employed by software and hardware developers who are interested in characterizing the dynamic behavior of complex software systems. However, despite the popularity of trace-driven analyses, there are surprisingly few options for encoding trace data…

Programs written for machine execution will always be susceptible to information theft. This information can include trademarked algorithms, data embedded in the program, or even data the program accesses. As technology advances computer scientists are building more and more powerful…

The pure methods in a program are those that exhibit functional or side effect free behaviour, a useful property of methods or code in the context of program optimization as well as program understanding. However, gathering purity data is not…

The largest naturally-occurring lake of hyperacid brine in the world is located in the crater of Kawah Ijen volcano in East Java, Indonesia. The hyperacid Banyu Pahit River flows down the side of Kawah Ijen and is a major source…

Designers of software components can use finite-state properties to denote behavioral interface specifications which enforce client-side programming rules that state how the components ought to be used. This allows users of these components to check their client code for compliance…
