Pileup mitigation at CMS in 13 TeV data
(IOP Publishing, 2020-09)With increasing instantaneous luminosity at the LHC come additional reconstruction challenges. At high luminosity, many collisions occur simultaneously within one proton-proton bunch crossing. The isolation of an interesting ... -
Porous materials
(Elsevier, 2018)Natural gas has received significant attention as a cleaner energy source alternative to gasoline. Natural gas consists of mainly methane (CH4); therefore, efficient storage of CH4 is essential to utilize natural gas. ... -

Prelude to part I
(Springer, 2018)Part I involves classical stochastic control problems, with a single decision maker acting repeatedly over time with its information set growing at each time stage. -
Prelude to part II
(Springer, 2018)In Part II, we focus on decentralized stochastic control problems and their applications. In Chapter 8, we present our results on the finite model approximation of multi-agent stochastic control problems (team decision ... -
