1. Importance of tannins for responses of aspen to anthropogenic nitrogen enrichment
Abstract : Boreal forests are often strongly nitrogen (N) limited. However, human activities are leading to increased N inputs into these ecosystems, through atmospheric N deposition and forest fertilization. READ MORE

2. Climate Simulation of an Attic Using Future Weather Data Sets - Statistical Methods for Data Processing and Analysis
Abstract : The effects of possible climate changes on a cold attic performance are considered in this work. The hygro-thermal responses of the attic to different climate data sets are simulated using a numerical model, which has been made using the International Building Physics Toolbox (IBPT). READ MORE

3. Electricity markets operation planning with risk-averse agents: stochastic decomposition and equilibium
Abstract : The growing penetration of renewable energy sources in electricity systems requires adapting operation models to face the inherent variability and uncertainty of wind or solar generation. In addition, the volatility of fuel prices (such as natural gas) or the uncertainty of the hydraulic natural inflows requires to take into account all these sources of uncertainty within the operation planning of the generation system.

4. Impacts and drivers of insect herbivory on element cycling in forests globally
Abstract : The effects of insect herbivores on forest functioning are not well understood even though they can have important impacts on ecosystem processes by intercepting foliage before resorption and depositing nutrient-rich materials to the soil. In this thesis, I investigated the impact and drivers of insect folivores on carbon (C), nitrogen (N), phosphorus (P) and silica (Si) cycling in broadleaf forests, and how this varies with major climate variables.

5. On the Dynamics and Statics of Power System Operation : Optimal Utilization of FACTS Devicesand Management of Wind Power Uncertainty
Abstract : Nowadays, power systems are dealing with some new challenges raisedby the major changes that have been taken place since 80’s, e.g., deregu-lation in electricity markets, significant increase of electricity demands andmore recently large-scale integration of renewable energy resources such aswind power.
