1. Sedimentation and Its Challenge for Sustainability of Hydraulic Structures : A Case Study of Mosul Dam Pumping Station
Abstract : A successful management and operation of water resources projects are essential to maintain their functions. Dams and reservoirs are one of the largest worldwide infrastructures. They serve one or more functions; reliable store and release of water for different purposes, hydropower generation and flood and draught controls. READ MORE

2. Dissolved Air Flotation
Abstract : Dissolved Air Flotation (DAF) is a well-established treatment method for water containing low density particles. The density-driven process is operated by the injection of water saturated with air under high pressure. At the pressure reduction microscopic air bubbles are formed. READ MORE

3. Lip-motion biometrics for audio-visual identity recognition
Abstract : Biometric recognition systems have been established as powerful security tools to prevent unknown users from entering high risk systems and areas. They are increasingly being utilized in surveillance and access management (city centers, banks, etc.) by using individuals' physical or biological characteristics. READ MORE

5. Weld Pool Simulations
Abstract : This investigation is devoted to the study of welding and its effect on the workpiece, focusing on the thermo and fluid dynamical phenomena occuring during a autogenous or nonautogenous arc fusion welding process. Its aim is to simulate the behaviour of the weld pool and analyze the consequence of the solid-liquid phase change, thus obtaining a methodology for predicting the appearance of weld defects related to solidification and cooling.
