A Graphic User Interface is developed to determine the existence of a particular sequence of piano notes within a monophonic sound waveform. Such waveforms are recorded within the Graphic User Interface and then passed to the monophonic analysis engine. The first phase of analysis segments the PCM sound data to localize the potential note locations. The second phase of analysis takes the segmented note locations, moves them to the frequency-domain, and utilizes a probabilistic identification process to determine the identity of each note. Two sound files can be processed together to decide if any notes are common between them. A frequency-based comparison model allows flexibility in finding overlap between the files. Theoretical concepts are visualized using the Graphic User Interface making it a tool for developing additional insight into the analysis of music. / Graduation date: 1997

Scientists in the biological sciences need to retrieve information from a variety of data collections, traditionally maintained in SQL databases, in order to conduct research. Because current assistant tools are designed primarily for business and financial users, scientists have been forced to use the notoriously difficult command-line SQL interface, supplied as standard by most database vendors. The goal of our research has been to establish the requirements of scientific researchers and develop specialized query assistance tools to help them query data collections across the Internet. This thesis describes our work in developing HyperSQL, a Web-to-database scripting language, and most importantly, Query Designer, a user-oriented tool for designing query interfaces directly on Web browsers. Current browsers (i.e., Netscape, Internet Explorer) do not easily interoperate with databases without extensive "CGI" (Common Gateway Interface) programming. HyperSQL is a scripting language that enables database administrators to construct forms-based query interfaces intended for end-users who are not proficient with SQL. Query results are formatted as hypertext-clickable links which can be used to browse the database for related information, bring up Web pages, or access remote search engines. HyperSQL query interfaces are independent of the database computer, making it possible to construct different interfaces targeting distinct groups of users. Capitalizing on our experience with HyperSQL, we developed Query Designer, a user-oriented tool for building query interfaces directly on Web browsers. No experience in SQL and HTML programming is necessary. After choosing a target database, the user can build a personalized query interface by making menu selections and filling out forms--the tool automatically establishes network connections, and composes HTML and SQL code. The automatically generated query form can be used immediately to issue a query, customized, or saved for later use. Results returned from the database are dynamically formatted into hypertext for navigating related information in the database. / Graduation date: 1997

The general problem of application development of interactive GUI applications has been addressed by toolkits, libraries, user interface management systems, and more recently domain-specific application frameworks. However, the most sophisticated solution offered by frameworks still lacks a number of features which are addressed by this research: 1) limited functionality -- the framework does little to help the developer implement the application's functionality. 2) weak model of the application -- the framework does not incorporate a strong model of the overall architecture of the application program. 3) representation of control sequences is difficult to understand, edit, and reuse -- higher-level, direct-manipulation tools are needed. We address these problems with a new framework design called Oregon Speedcode Universe version 3.0 (OSU v3.0) which is shown, by demonstration, to overcome the limitations above: 1) functionality is provided by a rich set of built-in functions organized as a class hierarchy, 2) a strong model is provided by OSU v3.0 in the form of a modified MVC paradigm, and a Petri net based sequencing language which together form the architectural structure of all applications produced by OSU v3.0. 3) representation of control sequences is easily constructed within OSU v3.0 using a Petri net editor, and other direct manipulation tools built on top of the framework. In ddition: 1) applications developed in OSU v3.0 are partially portable because the framework can be moved to another platform, and applications are dependent on the class hierarchy of OSU v3.0 rather than the operating system of a particular platform, 2) the functionality of OSU v3.0 is extendable through addition of classes, subclassing, and overriding of existing methods. The main contribution of this research is in the design of an application framework that uses Petri nets as the computational model of data processing in the synthesized application. OSU v3.0 is the first framework to formalize sequencing, and to show that complex GUI applications can indeed be quickly and reliably produced from such a framework. / Graduation date: 1992
