Solving The Search For Suitable Code: An Initial Implementation, Kathryn T. Stolee, Sebastian Elbaum Jun 2012

Solving The Search For Suitable Code: An Initial Implementation, Kathryn T. Stolee, Sebastian Elbaum

School of Computing: Technical Reports

Searching for code is a common task among programmers, with the ultimate goal of finding and reusing code or getting ideas for implementation. While the process of searching for code - issuing a query and selecting a relevant match - is straightforward, several costs must be balanced, including the costs of specifying the query, examining the results to find desired code, and not finding a relevant result. For the popular syntactic searches the query cost is quite low, but the results are often vague or irrelevant, so the examination cost is high and matches may not be found. Semantic searches …


Cogtool-Helper: Leveraging Gui Functional Testing Tools To Generate Predictive Human Performance Models, Amanda Swearngin May 2012

Cogtool-Helper: Leveraging Gui Functional Testing Tools To Generate Predictive Human Performance Models, Amanda Swearngin

School of Computing: Dissertations, Theses, and Student Research

Numerous tools and techniques for human performance modeling have been introduced in the field of human-computer interaction. With such tools comes the ability to model legacy applications. Models can be used to compare design ideas to existing applications, or to evaluate products against those of competitors. One such mod- eling tool, CogTool, allows user interface designers and analysts to mock up design ideas, demonstrate tasks, and obtain human performance predictions for those tasks. This is one step towards a simple and complete analysis process, but it still requires a large amount of manual work. Graphical user interface (GUI) testing tools …


Use Of Constraint Solving For Testing Software Product Lines, Jiangfan Shi Dec 2011

Use Of Constraint Solving For Testing Software Product Lines, Jiangfan Shi

School of Computing: Dissertations, Theses, and Student Research

A new software engineering methodology, software product line (SPL) engineering, has been increasingly studied in academia and adopted inindustry in the past decade. It allows the delivery of similar, but customized, software products to customers in the same domain within a short timeperiod. Software product line engineering produces an SPL by defining feature commonality and variability, and is supported by a well-managed asset base. SPL engineering can improve productivity from three to ten times, however, we require more efficient testing methods, so that we canensure the correctness of SPLs with the same resource allocation percentage as in the traditional software …


Refactoring Pipe-Like Mashups For End-User Programmers, Kathryn T. Stolee, Sebastian Elbaum Sep 2009

Refactoring Pipe-Like Mashups For End-User Programmers, Kathryn T. Stolee, Sebastian Elbaum

School of Computing: Technical Reports

Mashups are becoming increasingly popular as end users are able to easily access, manipulate, and compose data from many web sources. We have observed, however, that mashups tend to suffer from deficiencies that propagate as mashups are reused. To address these deficiencies, we would like to bring some of the benefits of software engineering techniques to the end users creating these programs. In this work, we focus on identifying code smells indicative of the deficiencies we observed in web mashups programmed in the popular Yahoo! Pipes environment. Through an empirical study, we explore the impact of those smells on end-user …


Getting Started With Prpl, Qingfeng Guan Apr 2008

Getting Started With Prpl, Qingfeng Guan

School of Natural Resources: Faculty Publications

pRPL is an open-source1 general-purpose parallel Raster Processing programming Library developed by Qingfeng Guan, in the Department of Geography, University of California, Santa Barbara. pRPL encapsulates complex parallel computing utilities and routines specifically for raster processing (e.g., raster data decomposition, distribution and gathering among multiple processors, inter-processor communication and data exchange), and provides an easy-to-use interface for users to parallelize almost any raster processing algorithm with any arbitrary neighborhood (or moving window) configuration. pRPL enables the implementation of parallel raster-processing algorithms without requiring a deep understanding of parallel computing and programming, thus it greatly reduces the development complexity. Moreover, even …
