Fast covariance estimation for high-dimensional functional data
For smoothing covariance functions, we propose two fast algorithms that scale linearly with the number of observations per function. Most available methods and software cannot smo...

Nonlinear kernel density principal component analysis with application to climate data
Abstract Principal component analysis (PCA) is a wellestablished tool for identifying the main sources of variation in multivariate data. However, as a linear method it cannot desc...

Schedulability analysis of a graph-based task model for mixed-criticality systems
Abstract We present a new graph-based real-time task model that can specify complex job arrival patterns and global state-based mode switching. The mode switching is of a mixed-cri...

Combined task- and network-level scheduling for distributed time-triggered systems
Ethernet-based time-triggered networks (e.g. TTEthernet) enable the cost-effective integration of safety-critical and real-time distributed applications in domains where determin...

Cache related pre-emption delays in hierarchical scheduling
— Hierarchical scheduling provides a means of composing multiple real-time applications onto a single processor such that the temporal requirements of each application are met. T...

On the compatibility of exact schedulability tests for global fixed priority pre-emptive scheduling with Audsley's optimal prior
Audsley’s Optimal Priority Assignment (OPA) algorithm can be applied to multiprocessor scheduling provided that three conditions hold with respect to the schedulability tests us...

The lower tail: Poisson approximation revisited
The well-known “Janson’s inequality” gives Poisson-like upper bounds for the lower tail probability P(X (1 − ε)EX) when X is the sum of dependent indicator random variabl...

Rumor spreading in random evolving graphs
In this paper, we aim at analyzing the classical information spreading Push protocol in dynamic networks. We consider the edgeMarkovian evolving graph model which captures natural ...
