assessing Software system maintainability using structural measures and expert assessments
International Conference on Software Maintenance, 2007Co-Authors: Bente AndaAbstract:Software maintenance is often expensive; hence, strategies for assessing the maintainability of complete Software systems are important. Nevertheless, a Software Client usually has few means of assessing the maintainability of a Software system as part of the acquisition process. Assessing the maintainability of complete systems is difficult due to the influence of many factors, such as the people, tasks and tools, in addition to the code. Furthermore, most research on maintainability focuses on individual classes of individual systems. This paper describes an empirical study in which the maintainability of four functionally equivalent systems developed in Java was assessed using both structural measures and expert assessments. The results suggest that such a combination may be useful. Although the assessment based on structural measures mostly corresponded with the expert assessments, there were several examples of potential problems regarding maintainability that were not captured by the structural measures.

scalable wavelet based video from server to hardware accelerated Client
IEEE Transactions on Multimedia, 2007Co-Authors: Hendrik Eeckhaut, Harald Devos, Peter Lambert, D De Schrijver, W Van Lancker, V Nollet, Prabhat Avasare, T Clerckx, F Verdicchio, Mark ChristiaensAbstract:Video source, carrier and Client diversification have led the video coding community to develop scalable video codecs supporting efficient decoding at varying resolution, frame rate and quality. Scalable video has several advantages over a nonscalable approach, but a large scale deployment is far from trivial and a lot of open questions remain. To resolve these, we developed a complete video delivery chain for scalable wavelet-based video. This includes a video server, a negotiation framework, a video scaling infrastructure and two scalable video Clients, one pure Software Client and one real-time, hardware accelerated Client. This paper describes the complete chain and identifies and quantifies the impact of using scalable video in every link of this chain.

nasa uas traffic management national campaign operations across six uas test sites
IEEE AIAA Digital Avionics Systems Conference, 2016Co-Authors: Joseph Rios, Daniel Mulfinger, Jeff Homola, Priya VenkatesanAbstract:NASA's Unmanned Aircraft Systems Traffic Management research aims to develop policies, procedures, requirements, and other artifacts to inform the implementation of a future system that enables small drones to access the low altitude airspace. In this endeavor, NASA conducted a geographically diverse flight test in conjunction with the FAA's six unmanned aircraft systems Test Sites. A control center at NASA Ames Research Center autonomously managed the airspace for all participants in eight states as they flew operations (both real and simulated). The system allowed for common situational awareness across all stakeholders, kept traffic procedurally separated, offered messages to inform the participants of activity relevant to their operations. Over the 3-hour test, 102 flight operations connected to the central research platform with 17 different vehicle types and 8 distinct Software Client implementations while seamlessly interacting with simulated traffic.
