The natural gas/diesel dual-fuel engine is an interesting technique to reduce greenhouse gas emission. A limitation of this concept is the emission of un-combusted methane. In this study we analyzed the influence of PFI gas-injection timing on cylinder to cylinder gas-distribution, and the resulting …

In this paper, a general approach for modeling airport operations is presented. Airport operations have been extensively studied in the last decades ranging from airspace, airside and landside operations. Due to the nature of the system, simulation techniques have emerged as a powerful approach for dealing …

This paper proposes an amendment of the classification of safety events based on their controllability and contemplates the potential of an event to escalate into higher severity classes. It considers (1) whether the end-user had the opportunity to intervene into the course of an event, (2) the level …

Trends and driving forces around us are moving fast in multiple directions. Technical developments in the fields of circular economy, internet of things, bio-based products, robotics, energy and materials are influencing and reshaping our transactional and contextual environment. To create integrated …

Uncertainty about requirements has a negative impact on project performance. In systems engineering, there is a process to assess requirements when they are transferred from client to contractor: the System Requirements Review (SRR). The aim of this process is for the contractor to decide if there is …
