Asynchronous task allocation is a fundamental problem in distributed computing in which p asynchronous processes must execute a set of m tasks. Also known as write-all or do-all, this problem been studied extensively, both independently and as a key buildi ...
These lectures present a research that investigates the representation of communities, and the way to foster their understanding by different audiences. Communities are complex multidimensional entities intrinsically difficult to represent synthetically ...
Climate change is expected to increase the magnitude and the frequency of extreme climatic events such as droughts. Better understanding how plant communities will respond to these droughts is a major challenge. We expect the response to be a shift in func ...
We study the complexity of gossip in an asynchronous, message-passing fault-prone distributed system. We show that an adaptive adversary can significantly hamper the spreading of a rumor, while an oblivious adversary cannot. The algorithmic techniques prop ...
This chapter describes an evolution of practices in community and business assurance from protective programs based upon risk management to the emerging strategy of resilience. The chapter compares and contrasts these two basic approaches, identifying nota ...
complexity and computational social sciences. This paper draws from explicit (phone calls, SMS messaging) and implicit (proximity sensing based on Bluetooth radio signals) interaction patterns collected via smartphones and reality mining techniques to expl ...
We introduce in this thesis the idea of a variable lookback model, i.e., a model whose predictions are based on a variable portion of the information set. We verify the intuition of this model in the context of experimental finance. We also propose a novel ...
As the Internet of Things grows to large scale, its components will increasingly be controlled by selfinterested agents. For example, sensor networks will evolve to community sensing where a community of agents combine their data into a single coherent str ...
It is estimated that the Maoist conflict has created 250,000 Internally Displaced Persons (IDPs) in Nepal. The livelihood questions of these IDPs are crucial to the state. However, knowledge on the livelihoods of these IDPs has mostly been derived from sho ...
Increasingly, multimedia collections are associated with networked communities consisting of interconnected groups of users who create, annotate, share, view, critique and remix collection content. Information arises within networked communities via connec ...
