With continuing trends towards miniaturization of circuits and inclusion of multiple, complex functionalities on a single chip, the effect of process variations on circuit performance is assuming critical importance. In view of increasing frequency of operation, accurate variability analysis of RF/Microwave circuits would require modeling of the variability(More)
As technologies continue to shrink in size, modeling the effect of process variations on circuit performance is assuming profound significance. Process variations affect the on-chip performance of both active and passive components. This necessitates the inclusion of the effect of these variations on distributed interconnect structures in modeling overall(More)
The explosion in social media adoption has opened up new opportunities for next-generation personalized web and information exchange in big data scenarios. Making sense of the massive number of overlapping streams of information generated by hundreds of millions of users on large social networks requires novel analytics and scalable computational(More)
We carefully revisit our definition of a social media signal from previous work both in terms of time-varying features within the data and the networked nature of the medium. Further, we detail our analysis of global patterns in Twitter over the month of June 2014, detect and categorize events, and illustrate how these analyses can be used to inform(More)
Computing the set of influential nodes of a given size, which when activated will ensure maximal spread of influence on a complex network, is a challenging problem impacting multiple applications. A rigorous approach to influence maximization involves utilization of optimization routines that come with a high computational cost. In this work, we propose to(More)
Synthesis of multi-GigaHertz radio frequency circuits brings together difficult challenges related to simulation, extraction and multidimensional space search. The standard approach of mapping all electromagnetic parasitics into parametric RLC models prior to synthesis is extremely restrictive especially when broadband and full-wave models with high(More)
This paper presents Microstrip antenna in the application for a satellite band microwave communication system for super high frequency (SHF), at a frequency range of 4.0 Ghz – 6.0Ghz. Currently, most security, research and education platforms are equipped with SHF communication systems. For their operational requirements, a design study is needed for the(More)
