Airport capacity, expressed as the maximum number of air traffic movements that can be accommodated during a given period of time under given conditions, has become a hard constraint to the air transportation, due to the scarce amount of resources on the ground and restrictions in the airspace. Usually the problem of capacity at airports is studied separating airspace operations from ground operations, but it is evident that the two areas are tied to each other. This work aims at developing a simulation model that takes into account both airspace and ground operations. The approach used is a divide and conquer approach, which allows the combination of four different models. The four models refer to the airside, and airspace operations. This approach allows to evaluate the system from diffrent angles depending on the scope of the study, the results show the analytic potential of this approach.
Anthropocentrism is the belief that value is human-centered and that all other beings are means to human ends. The Oxford English Dictionary defines anthropocentrism as “regarding humankind as the central or most important element of existence”. Anthropocentrism focuses on humanistic values as opposed to values found in non-human beings or ecosystems. With the popularization of the concept of ecosystem services, the idea of protecting the environment for the sake of human welfare is reflected in the SDGs. Within the SDGs, the instrumental use of the environment for the sake of alleviating poverty, combatting climate change, and addressing a range of other social and economic issues is promoted. Since the conception of the SDGs, there has been a discussion about anthropocentrism in ‘sustainable development’ (e.g., Kopnina 2016a and 2017, Strang 2017, Adelman 2018; Kotzé and French 2018) and how the SDGs can be antithetical to effective responses to sustainability challenges. The SDGs’ accent on economic growth and social equality as well as environmental protection actually result in ethical as well as practical paradoxes. While central to the SDG’s is ‘sustained and inclusive economic growth’ (UN 2015), the prioritization is on the economy, NOT the planet that nurtures both social and economic systems. Anthropocentrism, in this case, refers to the exclusive focus on short-term human benefits, whereas biodiversity loss is not considered a great moral wrong (Cafaro and Primack 2014). The three overarching anthropocentric SDG goals, economic growth, resilience, and inclusion, will be critically examined below and ways forward will be proposed. “This is a post-peer-review, pre-copyedit version of an article published in 'Encyclopedia of the UN Sustainable Development Goals.

Particle image velocimetry has been widely used in various sectors from the automotive to aviation, research, and development, energy, medical, turbines, reactors, electronics, education, refrigeration for flow characterization and investigation. In this study, articles examined in open literature containing the particle image velocimetry techniques are reviewed in terms of components, lasers, cameras, lenses, tracers, computers, synchronizers, and seeders. The results of the evaluation are categorized and explained within the tables and figures. It is anticipated that this paper will be a starting point for researchers willing to study in this area and industrial companies willing to include PIV experimenting in their portfolios. In addition, the study shows in detail the advantages and disadvantages of past and current technologies, which technologies in existing PIV laboratories can be renewed, and which components are used in the PIV laboratories to be installed.
