Recognizing standard computational structures (cliches) in a program can help an experienced programmer understand the program. We develop a graph parsing approach to automating program recognition in which programs and cliches are represented in an attributed graph grammar formalism and recognition is achieved by graph parsing. In studying this approach, we evaluate our representation's ability to suppress many common forms of variation which hinder recognition. We investigate the expressiveness of our graph grammar formalism for capturing programming cliches. We empirically and analytically study the computational cost of our recognition approach with respect to two medium-sized, real-world simulator programs.

Multiple research projects are proposed that utilize low-level knowledge of Field Programmable Gate Array (FPGA) and Application Specific Integrated Circuit (ASIC) design processes to enable additional research avenues. In order to accomplish these projects, Tools for Open Reconfigurable Computing (TORC) is utilized to provide a robust environment for circuit analysis and modifications. These projects rely on looking at the low-level constructs of the internals of these microchips. Through this knowledge, techniques for performing supply chain evaluations are proposed utilizing a non-binary comparison of multiple characteristic vectors between different FPGA manufacturing lots, and FPGAs that have been exposed to different environmental conditions. Second, techniques are proposed that look at design recovery by performing fuzzy segmentation and fuzzy matching algorithms to a problem area that has traditionally focused on exact graph sub-isomorphism solutions. Through these projects, additional research vectors are opened to protect and analyze the engineering efforts that are exerted in the design of FPGA and ASIC projects. / Ph. D.

A common problem experienced by the software engineering community traditionally has been that of understanding legacy code. A decade ago, legacy code was used to refer to programs written in COBOL, typically for large mainframe systems. However, current software developers predominantly use Object Oriented languages like C++ and Java. The belief prevalent among software developers and object philosophers that comprehending object-oriented software will be relatively easier has turned out to be a myth. Tomorrow's legacy code is being written today, since object oriented programs are even more complex and difficult to comprehend, unless rigorously documented. Reverse Engineering is a methodology that greatly reduces the time, effort and complexity involved in solving the program comprehension problem. This thesis deals with Reverse Engineering complex object oriented software and the experiences with a sample case study. Extensive survey of literature and contemporary research on reverse engineering and program comprehension was undertaken as part of this thesis work. An Energy Information System (EIS) application created by a leading energy service provider and one that is being used extensively in the real world was chosen as a case study. Reverse engineering this industry strength Java application necessitated the definition of a formal process. An intuitive Reverse Engineering Process (REP) was defined and used for the reverse engineering effort. The learning experiences gained from this case study are discussed in this thesis. / Master of Science

Fast development of services in the area of internet technology requires continuous research and development of software products, including information portals. Absence of documentation often limits the development of software products and increases the costs of maintenance of the product. It is essential to maintain or prepare, in case it is absent, quality documentation of the software in use to continue in portal's controlled development. Subject of this work is the analysis of services of internet information portal focused on tourism, specifically camping. The goal of the paper is to focus in detail on all services offered at the portal and subsequently analyse their benefits for the portal's users. We introduce basic terminology of internet portals. We introduce rules of usability and accessibility of web pages and their application for portal services. We describe the method of reverse engineering, that I use for update of the documentation of the services. The analysis is split in two phases. In the first phase, each service is described in detail and service's representation at higher abstraction level is created via reverse engineering. In the second phase we carry out and review questionnaire research. The research focuses on usage of the services by a group of potential customers. Based on the research carried out we conclude on recommendations about changes in further operation of the system.

The task of this thesis is the concept of restoration of the castle Zdislavice and its new use as a literary hotel, focusing on the personality of a prominent Austrian writer Marie Ebner-Eschenbach, née Dubská. My goal was to find use, which could be revived and could thus be preserved for future generations. Thanks to the personality of the writer, I decided to create site devoted to literature. I designed hotel for literary enthusiasts, linguists, copywriters and professionals. But also for visitors who are interested in the person of Marie Ebner-Eschenbach. There is also a restaurant, a literary cafe with an associated museum of the writer, chapel, banquet halls with potential uses for conference and library (three libraries). Part of the area is used as a park. It is designed as an English park, but part of the area closest to the castle is designed as a French garden. The tomb of Marie Ebner-Eschenbach is near the castle and is accessible via a staircase. Connection between tomb and castle is shown in the situration plan.
