We present a new approach to eliminate array bounds checks in Java by using static analyses. Our approach is based upon a flow-sensitive intraprocedural analysis called variable constraint analysis (VCA). VCA collects constraints between locals related to array references. The…

E-commerce is a new way of doing business. It is becoming increasingly important to everybody. The objective of this thesis is to compare various design approaches and to find out the best solution for small businesses. Some commonly used technologies…

In this thesis I examine the issues of sex education in Western and Javanese society using a conceptual-comparative approach. My main goal is to highlight the importance of sex education for young people in Javanese society. Research foci and discoveries…

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…

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…

This thesis is an attempt to study the role of Ahmad Surkati in al-Irshad movement in Java, and its implications for the Arab community in Indonesia. Surkati was a Sudanese Muslim scholar who, in 1911, came to Indonesia as one…

Side-effect analysis gives information about the set of locations that a statement may read or modify. This analysis can provide information useful in a compiler for performing aggressive optimizations. The impact of the use of side-effect analysis in compiler optimizations…

This thesis presents a novel idea for object allocation, cache line reservation (CLR), whose goal is to reduce data cache misses. Certain objects are allocated from "reserved" cache lines, so that they do not evict other objects that will be…

To achieve the best performance, most computer languages are compiled, either ahead of time and statically, or dynamically during runtime by means of a Just-in-Time (JIT) compiler. Optimizing compilers are complex, however, and for many languages such as Ruby, Python,…

A fundamental problem in interprocedural program analyses is the need to represent and manipulate collections of large sets. Binary Decision Diagrams (BDDs) are a data structure widely used in model checking to compactly encode large state sets. In this dissertation,…
