Visual programming languages employ visual representation to make programming easier and make programs more reliable and more accessible. Visual program testing becomes increasingly important as more and more visual programming languages and visual programming environments come into real use. In this work, we focus on one important class of visual...
Biologists need tools to see the structural relationships encoded in biological sequences (strings). The Walking Tree heuristics calculate some of these relationships. I have designed and implemented graphic presentations which allow the biologist (user) to see these relations. This thesis contains background information on the biological sequences and some background...
We developed a scientific information management system to facilitate remote access and analysis of earth and space science data, using the Component Model of software development provided by the Java language. The data sets are part of the Earth Observing. System project, being carried out at the College of Oceanic...
Guidelines for using style to improve computer program comprehension
have often been proposed without empirical testing. This thesis reports on the
results of three controlled experiments that investigated ways program style may be
used to aid comprehension of source code listings.
Experiments 1 and 2 were conducted using advanced computer...
Forms are an easy-to-use interface to access a database, including a remote database on the Internet. An entity-relationship (ER} diagram, which is a pictorial representation of a database schema, is widely used in designing a database. A class diagram, which shows set of classes, relationships among them, and associations, are...
Error-correcting output coding (ECOC) is a method for converting a k-classsupervised learning problem into a large number L of two-class supervised learningproblems and then combining the results of these L evaluations. Previous researchhas shown that ECOC can dramatically improve the classi cation accuracy of supervisedlearning algorithms that learn to classify...
Until now, most hypertext systems have been implemented on large scale computers. With improvements in microprocessors and development of graphical user interfaces, personal computers can run systems that previously needed the power of a mainframe. The low costs and widespread use of PCs will enable many people to use hypertext...
In this report., we address the issues of translating MATLAB scripts into SPMD-style C programs. The resulting programs, when linked with our run-time library are suitable for execution on parallel computers. We describe the design of the compiler and improvements made to it in the current version. We also describe...
There is a software gap in parallel processing. The short lifespan and small installation base of parallel architectures have made it economically infeasible to develop platform-specific parallel programming environments that deliver performance and programmability. One obvious solution is to build architecture-independent programming environments. But the architecture independence usually comes at...
