Safety and Security (S&S) have the same goal, that is to maintain the integrity of human, infrastructure, hardware, software, capital and intangible assets of a system. However, literature and practice indicate that the relationship between S&S has not yet been clearly defined and their boundaries remain …

Airports and surrounding airspaces are limited in terms of capacity and represent the major bottleneck in the air traffic management system. This paper proposes a two level model to tackle the integrated optimization problem of arrival, departure, and surface operations. The macroscopic level considers …

Ecosystem engineering research has recently demonstrated the fundamental importance of non-trophic interactions for food-web structure. Particularly, by creating benign conditions in stressful environments, ecosystem engineers create hot beds of elevated levels of recruitment, growth, and survival of …

Airports represent the major bottleneck in the air traffic management system with increasing traffic density. Enhanced levels of automation and coordination of surface operations are imperative to reduce congestion and to improve efficiency. This paper addresses the problem of comparing different control …

As a German conglomerate company specialized in electrical engineering and electronics, operates Siemens the world market with eight different divisions ranging from Power and Gas to Mobility. This study refers to the division Siemens Building Technologies (BT), the worlds market leader for energy efficient …

KLM is downsizing the full-freight cargo fleet in Schiphol Airport, for that reason it is important for the company and the airport to explore the consequences of moving the cargo transported by the full freighters into the bellies of the passenger flights. The consequences of this action in terms of …

Reading and writing is modelled in CSP using actions containing the symbols ? and !. These reading actions and writing actions are synchronous, and there is a one-to-one relationship between occurrences of pairs of these actions. In the CPA conference 2016, we introduced the half-synchronous alphabetised …

With sufficient electrical energy CO2 from the atmosphere, combined with water, can be converted to hydrocarbons. The first step in converting CO2 into a carbon based fuel is the dissociation of CO2 into CO and O. DIFFER explores the possibilities of this process by using a microwave plasma. This project …

Nutrient enrichment, scientifically known as eutrophication, is a worldwide problem. Eutrophication is one of the main drivers for cyanobacteria blooms. Cyanobacteria blooms can have a negative effect on ecology, economy and human health, as a result of to the ability of some species to release toxins. …
