Dynamical aspects of the regulation of bacterial proliferation

Galera Laporta, Letícia (Date of defense: 2019-02-08)

Bacterial proliferation has been studied for more than 100 years, but our knowledge of the mechanisms that control its dynamical aspects is still very limited. In this Thesis we have studied, at both singlecell and ...

Dynamical behavior of delay-coupled semiconductor lasers

Martínez González, Cristina (Date of defense: 2009-01-30)

In this Thesis we have presented the results of a set of experimental investigations of the dynamics of delay-coupled semiconductor lasers. The characterization of these systems includes topics such as the processing of ...

Dynamical Classification of some Birational Maps of C2

Zafar, Sundus (Date of defense: 2014-07-14)

This dissertation addresses three different problems in the study of discrete dynamical systems. Firstly, this work dynamically classifies a 9−parametric family of planar birational maps f : C2 → C2 that is f(x, y) = ...

The Dynamical State of Star-forming Regions, from Molecular Clouds to Massive Clumps

Lu, Zujia (Date of defense: 2022-04-26)

Star formation is a fundamental and still largely unsolved problem of astrophysics and cosmology. Its complexity stems from the complex interaction of turbulence, magnetic fields and gravity, and from the onset of different ...

Dynamics and biological information processing : from gene circuits to cellular populations

Gabaldà Sagarra, Marçal (Date of defense: 2017-01-23)

Living beings strive to survive and reproduce. To do so they need to monitor and adapt to a dynamic environment, taking advantage of the opportunities and dodging the threats that they may encounter. This thesis is devoted ...

Dynamics and control for continuous low-thrust spacecraft near collinear libration points

Gao, Chen (Date of defense: 2022-05-18)

Due to the rich dynamic properties of the equilibria of the Restricted Three Body Problem (RTBP), the libration point orbits (LPOs) around them are ideal locations for scientific missions. Fortunately, these invariant ...
