1. Parallel computing in model-based process engineering
Abstract : Chemical processes are usually expensive to run. To optimise a process, we need to know how the process behaves, and this is usually accomplished by studying the process experimentally. However, experiments are very expensive, particularly if an existing plant has to shut down normal operation to conduct an experiment. READ MORE

2. A Study of Mach 0.75 Jets and Their Radiated Sound Using Large-Eddy Simulation
Abstract : Large-Eddy Simulations (LES) of a compressible nozzle/jet configuration have been carried out. Two jets were simulated, an isothermal jet and a jet with a higher temperature than the surrounding air. The Mach number was in both cases 0.75 and the jet Reynolds number was 50,000. READ MORE

3. A Study of Subsonic Turbulent Jets and Their Radiated Sound Using Large-Eddy Simulation
Abstract : Stricter noise regulation for near-ground operations has made noise reduction in commercial aircraft a topic of growing interest in the aerospace industry. To meet airworthiness requirements new noise reduction technologies have to be developed and numerical methods for correct assessment of these technologies are desirable. READ MORE

4. Design of Integrated Building Blocks for the Digital/Analog Interface
Abstract : The integrated circuit has, since it was invented in the late 1950's, undergone a tremendous development and is today found in virtually all electric equipment. The small feature size and low production cost have made it possible to implement electronics in everyday objects ranging from computers and mobile phones to smart prize tags. READ MORE

5. On Modeling and Implementing Shopfloor Control Systems
Abstract : One of the key factors that hold shopfloor control (SFC) software evolution back is the exorbitant cost, time, complexity, and inflexibility of developing customized SFC software solutions. The development and maintenance life-cycle of SFC software is characterized by lock-in problems. READ MORE
