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)
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)
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)
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)
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)
This paper presents Microstrip antenna in the application for a military band short range radio communication system ultra high frequency(UHF), at a frequency range of 1Ghz – 1.5Ghz. Currently, most military aviation platforms are equipped with UHF communication system for their operational requirements, a design studies in the development for a(More)
We propose to use an 802.11 WLAN for a wireless intercom kind of scenario for enterprises. Replicating ordinary VoIP schemes leads to exceedingly low capacity. A scheme involving application layer merging of consecutive VoIP packets in the same host has been investigated to improve the capacity of VoIP over 802.11 WLANs. A simple analysis has been performed(More)
In this work we propose a novel formulation that models the attack and compromise on a cyber network as a combination of two parts - direct compromise of a host and the compromise occurring through the spread of the attack on the network from a compromised host. The model parameters for the nodes are a concise representation of the host profiles that can(More)
