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…

This thesis empirically compares statistical prediction models using fault count data and fault binary data. The types of statistical models that are studied in detail are Logistic Regression for binary data and Negative Binomial Regression for the count data. Different…

I present a distributed vision system for testing and development of computer vision algorithms. The system's form follows a new approach to the construction of vision systems. Utilizing streaming video interconnects and distributed computer resources, the system provides researchers with…

Geographical Information Systems (GIS) have become a more and more important application of database systems. Most general-purpose database systems do not contain a graphical display interface which is indispensable in GIS applications. This thesis presents the design and implementation of…

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,…

Mepiquat chloride (1.1 - dimethylpiperidinium chloride) are used to control excessive vegetative growth in cotton (Gossypium hirsutum L.) broadcast sprayed by ground or air. As proven by previous researches the variability of the cotton plants height in the field is…

The allocation of lock objects to critical sections in concurrent programs affects both performance and correctness. Traditionally, this allocation is done manually by the programmer. Recent work explores automatic lock allocation, aiming primarily to minimize conflicts and maximize parallelism by…

My dissertation explores the eclectic singing careers of sisters Eva and Juliette Gauthier. Born in Ottawa, Eva and Juliettte were aided in their musical aspirations by the patronage of Prime Minister Wilfred Laurier and his wife Lady Zoë. They both…
