The Impact of Information in Greedy Submodular Maximization
David Grimsman, Mohd. Shabbir Ali, João P. Hespanha +1
The maximization of submodular functions is an NP-Hard problem for certain subclasses of functions, for which a simple greedy algorithm has been shown to guarantee a solution whose…
LQ-optimal Sample-data Control under Stochastic Delays: Gridding Approach for Stabilizability and Detectability
Masashi Wakaiki, Masaki Ogura, Joao P. Hespanha
We solve a linear quadratic optimal control problem for sampled-data systems with stochastic delays. The delays are stochastically determined by the last few delays. The proposed o…
On the information in spike timing: neural codes derived from polychronous groups
Zhinus Marzi, Joao Hespanha, Upamanyu Madhow
There is growing evidence regarding the importance of spike timing in neural information processing, with even a small number of spikes carrying information, but computational mode…
RF Source Seeking using Frequency Measurements
Muhammed Faruk Gencel, Upamanyu Madhow, Joao Pedro Hespanha
In this paper, we consider a problem motivated by search-and-rescue applications, where an unmanned aerial vehicle (UAV) seeks to approach the vicinity of a distant quasi-stationar…
Realizing Uncertainty-Aware Timing Stack in Embedded Operating System
Amr Alanwar, Fatima M. Anwar, Joao P Hespanha +1
Time awareness is critical to a broad range of emerging applications -- in Cyber-Physical Systems and Internet of Things -- running on commodity platforms and operating systems. Tr…
SecSens: Secure State Estimation with Application to Localization and Time Synchronization
Amr Alanwar, Bernhard Etzlinger, Henrique Ferraz +2
Research evidence in Cyber-Physical Systems (CPS) shows that the introduced tight coupling of information technology with physical sensing and actuation leads to more vulnerability…
