6. Wireless Sensor Networks in Smart Cities : The Monitoring of Water Distribution Networks Case
Abstract : The development of wireless sensor networks (WSNs) is making it possible to monitor our cities. Due to the small size of the sensor nodes, and their capabilities of transmitting data remotely, they can be deployed at locations that are not easy or impossible to access, such as the pipelines of water distribution networks (WDNs), which plays an important role in protecting environment and securing public health.

7. Free Volume Determination in Polymers and Polymer Blends
Abstract : The free volume of a polymer, which corresponds to the unoccupied regions accessible to segmental motions, is an important parameter for understanding and predicting many of its characteristic properties. The concept of free volume is the basis for understanding the molecular mobility in polymers. READ MORE

8. Lithium-ion battery models for performance and aging
Abstract : The demand for lithium-ion batteries (LiBs) is increasing at an exponential rate, so is the need to understand their behaviors and properties.In this pursuit, models are useful tools for improving cell design,quality, control system, keeping track of performance, aging andlifetime.

9. Interpretable Battery Lifetime Prediction Using Early Degradation Data
Abstract : Battery lifetime prediction using early degradation data is crucial for optimizing the lifecycle management of batteries from cradle to grave, one example is the management of an increasing number of batteries at the end of their first lives at lower economic and technical risk. In this thesis, we first introduce quantile regression forests (QRF) model to provide both cycle life point prediction and range prediction with uncertainty quantified as the width of the prediction interval.

10. Studies of collective phenomena in neutron deficient nuclei : by means of lifetime measurements, angular correlation measurements and the recoil-decay tagging technique
Abstract : The nucleus is a mesoscopic system that retains features from both the quantum and macroscopic worlds. A basic property of a macroscopic body is its shape. Nuclear shapes can be deduced from experimental data as they influence the excitation mode of the nucleus and hence the energies and lifetimes of its excited levels. READ MORE
