Sensing-throughput tradeoff for cognitive radio networks
- in Proc. IEEE Int. Conf. Commun.(ICC
, 2006
"... Abstract—In a cognitive radio network, the secondary users are allowed to utilize the frequency bands of primary users when these bands are not currently being used. To support this spectrum reuse functionality, the secondary users are required to sense the radio frequency environment, and once the ..."

However, from the secondary users ’ perspec-tive, the lower the probability of false alarm, the more chances the channel can be reused when it is available, thus the higher the achievable
SCHEDULING IN DISTRIBUTED SYSTEMS: A SURVEY AND FUTURE PERSPECIVE

Designing Knowledge-assisted Visual Analytics Systems for Organizational Environments
"... We present research focused on designing knowledge-assisted visual analytics (VA) systems for workers in organizational environments. We focus on business an-alysts and asset managers, who work collaboratively to analyze information and make decisions. Through extensive investigations in two organiz ..."

Their current tools lack support for aggregat-ing, organizing, and sharing such information. To ad-dress their needs, we characterized their analytic work-flows, extracted
A Study on Prioritisation of Impact Analysis Issues: A Comparison Between Perspectives Per Jönsson
"... Impact analysis, which concerns the analysis of the impact of proposed changes to a system, is an important change man-agement activity that previously has been studied mostly with respect to technical aspects. In this paper, we present results from a study where issues with impact analysis were pri ..."

VELDA: Relating an Image Tweet’s Text and Images
"... Image tweets are becoming a prevalent form of social media, but little is known about their content – textual and visual – and the relationship between the two medi-ums. Our analysis of image tweets shows that while vi-sual elements certainly play a large role in image-text relationships, other fact ..."
