Maria Duque defended her thesis co-directed by Cristina Masoller and Jordi Tiana on December 5 at the Terrassa Campus. Entitled "Experimental study of the coherence of the light emitted by a semiconductor laser with optical feedback", the thesis studies the appearance and evolution of coherence during laser start-up in different optical feedback scenarios. In addition, the impact of sinusoidal modulation in the injection current on the coherence of lasers is investigated and includes a chapter on the impact of optical injection

Refrigeration systems contribute significantly to climate change. Now, a European Consortium involving institutions from France, Slovenia, United Kingdom and Spain, has been awarded with 3.4M euros EU grant for the next 4 years to develop a new all-solid refrigeration technology based on the energy exchanged during spin transitions driven by pressure: the FROSTBIT project

Eda Vurgun defended her doctoral tesis entitled “Compact binary millisecond pulsars: X-ray observations and numerical simulations” on November 7, 2024 at the Besòs Campus. The thesis has been co-directed by Domingo García Senz and Manuel Linares Alegret

Anurag Surapaneni defended his thesis supervised by Dr. Daniel Mira on October 30, 2024 at the Barcelona Supercomputing Center (BSC). Entitled "Multi-regime combustion modelling in high-fidelity numerical simulations of reacting flows" the thesis focuses on developing high-fidelity numerical combustion models for simulation reacting flow with mixture inhomogeneity and under complex combustion regimes.

The candidate Mehran Nabahat defended his thesis, directed by Eloi Pineda, on October 10, 2024 at the Diagonal Besòs Campus. Entitled "Dynamic Heterogeneity in Metallic Glasses: Study of Structural Relaxation, Aging, and Mechanical Properties of Vit4 alloy", the thesis presents a study of the evolution of the structural dynamics of an alloy in the vitreous state

Homeyra Khaledian defended her thesis, co-supervised by Prof. Xavier Prats and Prof. Jordi Vilà Valls, on September 19, 2024, at the Baix Llobregat Campus in Castelldefels. Entitled "Aircraft Trajectory Estimation and Guidance Mode Identification using Bayesian Filtering Techniques", the thesis focuses on real-time aircraft trajectory estimation and real-time guidance mode identification, which are needed for achieving accurate aircraft trajectory prediction.

The student Rathan B. Athota defended his thesis co-supervised by Adeline de Villardi de Montlaur and José I. Rojas Gregorio on September 19 at Campus Nord. The thesis, entitled "Numerical analysis of thermally-driven winds in mountain-valley regions", presents a numerical study of the formation of thermally-driven winds on slopes of mountain-valley systems, using open source computational fluid dynamics software. These winds occur on the aforementioned slopes due to temperature gradients by the lower atmosphere’s diurnal heating-cooling cycle. The results of this research may be interesting for applications in wind energy.
