One of the many challenges of software development and maintenance is the need to collaborate among many constituents and stakeholders. For example, clients interact with software development organizations; software-development organizations consist of many developers and maintainers within the same location and across different locations; and the development organization often outsources some of the testing efforts to independent test agencies. Each of these parties may reside in different locations, often across many very disparate time zones.
Research shows that sharing one’s location can help people stay connected, coordinate daily activities, and provide a sense of comfort and safety . Recently, smartphones and location-based services (LBS) have become widely available in developed countries , but only a small percentage of smartphone users have ever tried sharing location with other people . Our work aims to understand real-world factors shaping behaviors and attitudes towards social location-sharing, especially in regards to why people avoid or abandon the technology, or limit their usage.
When there is a major environmental disruption such as a natural disaster or war, it is not only the technical infrastructure that needs to be repaired but also the human infrastructure. I am currently studying collaboration resilience-the extent to which people continue to work and socialize despite such a disruption. In this project we are examining the role that information technology plays in helping people repair their human infrastructure.
This research focuses on techniques for identifying and reducing the costs, streamlining the process, and improving the readiness of future workforce for the acquisition of complex software systems. Emphasis is directed at identifying, tracking, and analyzing software component costs and cost reduction opportunities within acquisition life cycle of open architecture (OA) systems, where such systems combine best-of-breed software components and software products lines (SPLs) that are subject to different intellectual property (IP) license requirements.
We developed techniques for clustering of failures. Failure-clustering techniques attempt to categorize failing test cases according to the bugs that caused them. Test cases are clustered by utilizing their execution profiles (gathered from instrumented versions of the code) as a means to encode the behavior of those executions. Such techniques can offer suggestions for duplicate submissions of bug reports.
The dynamic nature of markets wherein business relationships are established and dissolved continuously demands systems that can cope with constant change, and do so with security paramount. These relationships are reified as services that are offered by organizations and used within a spectrum of domains and use contexts. Current service technologies fail to meet the requirements, however; interfaces are rigid, non-secure, and “one-size-fits-all solutions” which hardly meet the demands of any of its users.
Software designers frequently sketch when they design, particularly during the early phases of exploration of a design problem and its solution. In so doing, they shun formal design tools, opting for the whiteboard of pen/paper instead. Calico is a sketch-based distributed software design tool that supports software designers with a variety of features that improve over the use of just pen-and-paper or a regular whiteboard, and are tailored specifically for early software design on tablets and electronic whiteboards.
Sourcerer is an ongoing research project at the University of California, Irvine aimed at exploring open source projects through the use of code analysis. The existence of an extremely large body of open source code presents a tremendous opportunity for software engineering research. Not only do we leverage this code for our own research, but we provide the open source Sourcerer Infrastructure and curated datasets for other researchers to use.
The Sourcerer Infrastructure is composed of a number of layers.
