Weld Pool Oscillation during Gas Tungsten Arc Welding

Interface Characterization and Failure Modeling for Semiconductor Application

Due to the fact that microelectronics is made up from various materials with highly dissimilar thermo-mechanical properties, generally the interface between two adjacent materials is the place where delamination related failure most likely would occur. Failure of these interfaces results in decreased reliability and loss of performance of...

Towards a Performance Evaluation Method for Durable and Sustainable Thin Surfacings

Thin surfacings are widely used as surface layers to provide additional functions and to extend the service life of existing pavements. They can protect the treated road surfaces from external aggressive substances, the degeneration process of weather and the ageing caused by Ultraviolet light and oxygen. Antiskid surfacing is one type of thin...

Ergonomic Factors during Laparoscopic Surgery Training

With the introduction of minimally invasive surgery (MIS), the patient experiences the benefits of less pain, a more rapid recovery and a shorter stay in hospital. However, MIS provides many challenges to surgeons and they need extensive training to acquire this new technique. This training consists of developing cognitive, clinical, and...

Ships in an Artificial Force Field: A Multi-agent System for Nautical Traffic and Safety

The main objective of this research is developing a simulation tool that provides information of detailed ship behavior in a specific navigational environment, on both the ship traffic level and the individual ship level, for safety analysis, decision making, planning of ports and waterways, and design of mitigation measures. In this research,...

Cooperative Adaptive Cruise Control Vehicles on Highways: Modelling and Traffic Flow Characteristics

Traffic congestion causes detrimental effects on economy and society in terms of travel time delay, increased vehicle collision risk and increased air pollution. To tackle that, new intelligent transportation systems are being developed. One of these emerging technologies comprise automated driving systems. Adaptive Cruise Control (ACC),...

Surrogate-assisted reservoir history matching

In the community of petroleum engineering, the use of surrogate modelling techniques have recently gained more and more popularity to improve the efficiency of history matching. However, it is still not possible to fully utilize their potential in realistic applications. One of the challenges is to retain high accuracy while increasing the...

Structural health monitoring of the additively manufactured structures with embedded fiber optic sensors

Additively manufacturing can bring opportunities and risk factors to the aerospace industry. On one hand, additive manufacturing allows the manufacturing of structures with geometries that are difficult or impossible to fabricatewith conventional machining procedures. This geometry flexibility may lead to components with a greater strength-to...
