Resource Allocation Strategies in a 2-Level Hierarchical Grid System
Efficient job scheduling in grids is challenging due to the large number of distributed autonomous resources. In this paper we study various resource allocation policies in a 2-le...

Adjoint-Based Optimal Control of the Expected Exit Time for Stochastic Hybrid Systems
Abstract. In this paper, we study the problem of controlling the expected exit time from a region for a class of stochastic hybrid systems. That is, we find the least costly feedb...

Rendering The First Star In The Universe - A Case Study
For quantitative examination of phenomena that simultaneously occur on very different spatial and temporal scales, adaptive hierarchical schemes are required. A special numerical ...

Observability of Switched Linear Systems in Continuous Time
Abstract. We study continuous-time switched linear systems with unobserved and exogenous mode signals. We analyze the observability of the initial state and initial mode under arbi...

A descent algorithm for the optimal control of constrained nonlinear switched dynamical systems
One of the oldest problems in the study of dynamical systems is the calculation of an optimal control. Though the determination of a numerical solution for the general nonconvex o...
