Machine learning in process systems engineering: Challenges and opportunities

This “white paper” is a concise perspective of the potential of machine learning in the process systems engineering (PSE) domain, based on a session during FIPSE 5, held in Crete, Greece, June 27–29, 2022. The session included two invited talks and three short contributed presentations followed by extensive discussions. This paper does not...

Multi-objective design of aircraft maintenance using Gaussian process learning and adaptive sampling

Aircraft maintenance design aims to identify strategies that render the aircraft reliable for flight in a cost-efficient manner. These are often conflicting objectives. Moreover, existing studies on maintenance design often limit themselves to only one type of maintenance strategy, overlooking other potentially dominating designs. We propose...

Evaluation of a full-scale suspended sludge deammonification technology coupled with an hydrocyclone to treat thermal hydrolysis dewatering liquors

Suspended sludge deammonification technologies are frequently applied for sidestream ammonia removal from dewatering liquors resulting from a thermal hydrolysis anaerobic digestion (THP/AD) process. This study aimed at optimizing the operation, evaluate the performance and stability of a full-scale suspended sludge continuous stirred tank...

An integrated assessment of safety and efficiency of aircraft maintenance strategies using agent-based modelling and stochastic Petri nets

Aircraft maintenance is key for safe and efficient aircraft operations. While most studies propose cost-efficient maintenance strategies, the safety and efficiency of these strategies need to be quantified. This paper proposes a formal framework to assess the safety and efficiency of maintenance strategies by means of agent-based modelling,...

Application of 3D scanning in design education

Three-dimensional scanning technologies have brought great opportunities in ergonomic and product design education as well as research. Not only the anthropometric size but also the shape and posture of the human, form of a product, or interactions between the human and product obtained based on the 3D scanning have been usefully applied in...

Urban Stitch: A new urban design approach to transportation infrastructure renewal projects

The history of Taiwan is closely attached to the establishment of transportation infrastructure. The thriving scene of urban Taiwan emerged in the 70s after the establishment of several national level infrastructure projects. They have become the backbone of both Taiwan's past economic glory as well the daily necessity of present society. As the...

Laser-driven resonance of dye-doped oil-coated microbubbles: Experimental study

Photoacoustic (PA) imaging offers several attractive features as a biomedical imaging modality, including excellent spatial resolution and functional information such as tissue oxygenation. A key limitation, however, is the contrast to noise ratio that can be obtained from tissue depths greater than 1-2 mm. Microbubbles coated with an...
