Machine Learning Meets Quantitative Planning: Enabling Self-Adaptation in Autonomous Robots [article]

Pooyan Jamshidi, Javier Cámara, Bradley Schmerl, Christian Kästner, David Garlan
2019 arXiv   pre-print
However, for systems that are highly configurable, such planning becomes intractable due to the size of the adaptation space.  ...  To overcome this challenge, in this paper we explore an approach that (a) uses machine learning to find Pareto-optimal configurations without needing to explore every configuration and (b) restricts the  ...  This work has been also supported in part by the National Science Foundation (awards 1318808, 1552944, and 1717022).  ...

2008 Proceedings of the 18th ACM Great Lakes symposium on VLSI - GLSVLSI '08

Stability of Many-Body Localized Systems Coupled to Small Bath [article]

Shao-Hen Chiew, Jiangbin Gong, Leong-Chuan Kwek, Chee-Kong Lee
2021 arXiv   pre-print
However, in cases where the system and environment is strongly coupled in the ladder configuration, the eventual localization properties are highly dependent on the initial state, and could lead to either  ...  Our numerical results indicate that in most cases, the system retains its localization properties despite the coupling to the finite environment, albeit to a reduced extent.  ...  To study the steadystate localization properties of the system, we initialize the total system in a highly non-thermal initial product state |ψ(0) = |ψ s (0) ⊗ |ψ e (0) , allow it to evolve under H, and  ...

Polyomino Models of Surface Supramolecular Assembly: Design Constraints and Structural Selectivity [article]

Joel Nicholls, Gareth P. Alexander, David Quigley
2017 arXiv   pre-print
We examine emergent properties of 2D supramolecular networks, using enumeration of configurations formed by interacting dominoes on square lattices as a simple model system.  ...  We then introduce kinetics as simple local rearrangements.  ...  If only local rearrangements are possible after adsorption, then the system is trapped in the connected component of the initial configuration, thereby giving the system a new set of possible effective  ...

The Economic, Institutional, and Political Determinants of Public Health Delivery System Structures

Richard C. Ingram, F. Douglas Scutchfield, Glen P. Mays, Michelyn W. Bhandari
2012 Public health reports (1974)  
We present a qualitative exploration of the factors that determine variation and change in the seven structural configurations that comprise the local public health delivery system typology.  ...  A typology of local public health systems was recently introduced, and a large degree of structural transformation over time was discovered in the systems analyzed.  ...  Configuration seven: distributed limited systems Both configuration seven systems experienced decreased state funds; however, the agency in the stable system used local funds to offset losses at the state  ...
