We report a systematic study of the C(2)1Πuelectronic state in rubidium dimer, observed in polarization labelling spectroscopy experiment through the C ← X1Σg+ transitions recorded under rotational resolution in two isotopologues 85Rb2 and 85Rb87Rb. Regularity of the vibrational progressions was distorted by numerous interactions with the surroundi...
In this thesis, optimal traffic control of congestion regimes is investigated to reject the disturbances and to stabilize the traffic. The disturbance applies at the boundary of the traffic flow model. In order to analyze and design the optimal PI controller for the linearized Aw-Rascle-Zhang model, the L_2 gain is computed to estimate the disturba...

Our aim was to quantify the role of metabolic energy cost in governing neuromuscular adaptation to prolonged exposure to optical flow walking balance perturbations in young adults. We hypothesized that metabolic cost would increase at the onset of balance perturbations in a manner consistent with wider and shorter steps and increased step-to-step v...

Strong, long-range persistent correlations in stride time (ST) and length (SL) are the fundamental traits of treadmill gait. Our recent work showed that the ST and SL time series' statistical properties originated from the superposition of large-scale trends and small-scale fluctuations (residuals). Trends served as the control manifolds about whic...

Cognitive-walking interference is manifested when simultaneously performing a cognitive task while walking. However, majority of the dual-task walking paradigms incorporated relatively short testing trials and were focused on posing a cognitive challenge by adding a secondary cognitive task but not introducing walking perturbations. How do healthy ...

Thermodynamic and kinetic components of density functional reactivity theory -based stabilization energies between interacting electron acceptors and electron donors are evaluated with and without taking into account perturbative effects on one reactant caused by the other. The values of the two energy components generated through these two approac...
In addition to operating close to their maximum capacity, transport networks, and especially the urban ones, are subject to various disruptions induced by human, technical or natural factors, which often generate loss of performance, damages and high maintenance costs. Introduced in the 70's, the notion of resilience represents the ability of a sys...
Microbes are impacted by environmental disturbances affecting the functional stability of microbial communities. However, their responses are complex, difficult to elucidate and the mechanics of functional stability are still poorly understood. In this thesis, I investigated microbial responses to environmental disturbances from single populations ...

BackgroundAs hyperactive muscle stretch reflexes hinder movement in patients with central nervous system disorders, they are a common target of treatment. To improve treatment evaluation, hyperactive reflexes should be assessed during activities as walking rather than passively. This study systematically explores the feasibility, reliability and va...
To compare the responses in knee joint muscle activation patterns to different perturbations during gait in healthy subjects. Nine healthy participants were subjected to perturbed walking on a split-belt treadmill. Four perturbation types were applied, each at five intensities. The activations of seven muscles surrounding the knee were measured usi...
