Java decompilers convert Java class files to Java source. Common Java decompilers are javac-specific decompilers since they target bytecode produced from a particular javac compiler. We present work carried out on Dava, a tool-independent decompiler that decompiles bytecode produced from…

It is a common practice to retrieve code from an outside source, execute it and return the result to the user. During execution secure data can enter the program by user input or access of a data resource. It is…

Despite the popularity of Java, problems may arise from potential data-race conditionsduring execution of a Java program. Data-races are considered errors in concurrent pro-gramming languages and greatly complicate both programming and runtime optimizationefforts. A race-free version of Java is therefore…

For many years, programmers have faced the problem of reading and trying to understand other programmers' code, either to maintain it or to learn from it. Analysis of dynamic data structure usage is useful for both program understanding and for…

Speculative multithreading (SpMT), also known as thread level speculation (TLS), is a dynamic parallelization technique that relies on out-of-order execution, dependence buffering, and misspeculation rollback to achieve speedup of sequential programs on multiprocessors. A large number of hardware studies have…

Numerous techniques mine change data captured in software archives to assist software engineering efforts. These change-based approaches typically analyze change sets -- groups of co-committed changes -- under the assumption that the development work represented by change sets is both…

High-sulfidation epithermal deposits are genetically associated with calc-alkaline volcanism in subduction zones, and although these ore deposits are excellent places to focus research, subduction zone stratovolcanoes provide important windows on magmatic-hydrothermal processes that are not available from study of the…

This dissertation examines a number of syntactic and semantic aspects of the full set of TAM (tense-aspect-modal) markers in the dialect of Paciran Javanese (Western Malayo-Polynesian, Austronesian), spoken in East Java, Indonesia.First, I identify the inventory of TAM markers in…

The aim of this study was to characterise the quality and levels of bioactive compounds in the fruit of 22 foreign accessions of the mango belonging to the Active Germplasm Bank of Embrapa Semiárido. Sixty fruits from each of the…
