Kolmogorov extension theorem for general (quantum) stochastic processesDec 07 2017In classical physics, the Kolmogorov extension theorem provides the foundation for the definition and investigation of stochastic processes. In its original form, it does not hold in quantum mechanics. More generally, it does not hold in any theory -- ... More
Non-Markovian quantum control as coherent stochastic trajectoriesFeb 09 2018Feb 12 2018We develop a notion of stochastic quantum trajectories. First, we construct a basis set of trajectories, called elementary trajectories, and go on to show that any quantum dynamical process, including those that are non-Markovian, can be expressed as ...

Characterization of a quasi-static environment with a qubitMar 15 2019We consider a qubit initalized in a superposition of its pointer states, exposed to pure dephasing due to coupling to a quasi-static environment, and subjected to a sequence of single-shot measurements projecting it on chosen superpositions. We show how ... More

Kolmogorov extension theorem for (quantum) causal modelling and general probabilistic theoriesDec 07 2017Jul 07 2018In classical physics, the Kolmogorov extension theorem lays the foundation for the theory of stochastic processes. It has been known for a long time that, in its original form, this theorem does not hold in quantum mechanics. More generally, it does not ... More
Eigenvalues of Dirichlet Laplacian within the class of open sets with constant diameterJan 12 2018This paper is about a shape optimization problem related to the Dirichlet Laplacian eingevalues in the Euclidean plane. More precisely we study the shape of the minimizer in the class of open sets of constant width. We prove that the disk is not a local ... More
An Evaluation of Structural Parameters for Probabilistic Reasoning: Results on Benchmark CircuitsFeb 13 2013Many algorithms for processing probabilistic networks are dependent on the topological properties of the problem's structure. Such algorithms (e.g., clustering, conditioning) are effective only if the problem has a sparse graph captured by parameters ... More

Optimising Rule-Based Classification in Temporal DataJul 20 2016This study optimises manually derived rule-based expert system classification of objects according to changes in their properties over time. One of the key challenges that this study tries to address is how to classify objects that exhibit changes in ... More
Measuring Player's Behaviour Change over Time in Public Goods GameSep 09 2016An important issue in public goods game is whether player's behaviour changes over time, and if so, how significant it is. In this game players can be classified into different groups according to the level of their participation in the public good. This ... More
Semiparametric estimation for space-time max-stable processes: F -madogram-based estimation approachMay 20 2019Max-stable processes have been expanded to quantify extremal dependence in spatio-temporal data. Due to the interaction between space and time, spatio-temporal data are often complex to analyze. So, characterizing these dependencies is one of the crucial ... More
Censored pairwise likelihood-based tests for mixing coefficient of spatial max-mixture modelsDec 08 2017Max-mixture processes are defined as Z = max(aX, (1 -- a)Y) with X an asymptotic dependent (AD) process, Y an asymptotic independent (AI) process and a $\in$ [0, 1]. So that, the mixing coefficient a may reveal the strength of the AD part present in the ... More
Back-to-back Converter Control of Grid-connected Wind Turbine to Mitigate Voltage Drop Caused by FaultsJul 11 2017Power electronic converters enable wind turbines, operating at variable speed, to generate electricity more efficiently. Among variable speed operating turbine generators, permanent magnetic synchronous generator (PMSG) has got more attentions due to ... More
A Model-Free Selection Criterion For The Mixing Coefficient Of Spatial Max-Mixture ModelsJan 03 2018One of the main concerns in extreme value theory is to quantify the dependence between joint tails. Using stochastic processes that lack flexibility in the joint tail may lead to severe under-or over-estimation of probabilities associated to simultaneous ... More
Control of the electromagnetic environment of a quantum emitter by shaping the vacuum field in a coupled-cavity systemMar 20 2015We propose a scheme for the ultrafast control of the emitter-field coupling rate in cavity quantum electrodynamics. This is achieved by the control of the vacuum field seen by the emitter through a modulation of the optical modes in a coupled-cavity structure. ... More
