A hierarchical modelling framework for estimating individual‐ and population‐level reproductive success from movement data

open access: yesMethods in Ecology and Evolution, 2023
Rapidly advancing animal telemetry technologies paired with new statistical models can provide insight into the behaviour of otherwise unobservable free‐living animals.

Data-Driven Suboptimal Scheduling of Switched Systems

open access: yesSensors, 2020
In this paper, a data-driven optimal scheduling approach is investigated for continuous-time switched systems with unknown subsystems and infinite-horizon cost functions.

Continuous-time cascaded ΣΔ modulators for VDSL: A comparative study [PDF]

open access: yes, 2005
This paper describes new cascaded continuous-time ΣΔ modulators intended to cope with very high-rate digital subscriber line specifications, i.e 12-bit resolution within a 20-MHz signal bandwidth.

Continuous Time Random Walks (CTRWs): Simulation of continuous trajectories [PDF]

open access: yes, 2007
Continuous time random walks have been developed as a straightforward generalisation of classical random walk processes. Some 10 years ago, Fogedby introduced a continuous representation of these processes by means of a set of Langevin equations [H.

Continuous-time perpetuities and time reversal of diffusions [PDF]

open access: yes, 2016
We consider the problem of estimating the joint distribution of a continuous-time perpetuity and the underlying factors which govern the cash flow rate, in an ergodic Markov model. Two approaches are used to obtain the distribution.

Imprecise Continuous-Time Markov Chains [PDF]

open access: yes, 2017
Continuous-time Markov chains are mathematical models that are used to describe the state-evolution of dynamical systems under stochastic uncertainty, and have found widespread applications in various fields. In order to make these models computationally

Continuous-Time Adaptive Critics [PDF]

open access: yesIEEE Transactions on Neural Networks, 2007
A continuous-time formulation of an adaptive critic design (ACD) is investigated. Connections to the discrete case are made, where backpropagation through time (BPTT) and real-time recurrent learning (RTRL) are prevalent. Practical benefits are that this framework fits in well with plant descriptions given by differential equations and that any ...

Continuous Time Channels with Interference [PDF]

open access: yes, 2012
Khanna and Sudan \cite{KS11} studied a natural model of continuous time channels where signals are corrupted by the effects of both noise and delay, and showed that, surprisingly, in some cases both are not enough to prevent such channels from achieving ...

Distributed Synthesis in Continuous Time [PDF]

open access: yes, 2016
We introduce a formalism modelling communication of distributed agents strictly in continuous-time. Within this framework, we study the problem of synthesising local strategies for individual agents such that a specified set of goal states is reached, or

Optimality conditions for isoperimetric continuous - time optimization problems [PDF]

open access: yesYugoslav Journal of Operations Research, 2023
In this paper we deal with a nonsmooth case of isoperimetric convex continuoustime programming problem with inequality integral constraint and phase constraint, defined in L∞([0, T],Rn). In order to obtain necessary optimality conditions for this problem,
