The airport of Mexico City has been declared saturated for most of the day. For that reason, the Mexican government announced a couple of years ago the construction of a completely new one which is supposed to be operative in 2020 in its first phase. However, the technical issues and the economic downturn in the country jeopardise the project; for that reason, it is important to have alternatives that allow investing in a progressive fashion so that the investments are not lost or end up in useless infrastructure like the ones that have taken place in other parts of the world. The current work presents a simulation-based study of the alternative of using one of the runways of the new airport in a remote fashion in case the original project is delayed or even cancelled. The results indicate that the proposed infrastructure alleviates the congestion problem in the current airport, and at the same time allows the traffic growth with performance indicators similar to airports that have remote runways as in the case of Schiphol in The Netherlands.

Dit eindrapport behandelt het onderzoek van CDM@Airports, gericht op Collaborative Decision Making in de logistieke processen van luchtvrachtafhandeling op Nederlandse luchthavens. Dit project, met een looptijd van ruim twee jaar, is gestart op 8 november 2021 en geëindigd op 31 december 2023. HET PROJECT CDM@AIRPORTS OMVAT DRIE WERKPAKKETTEN: 1. Projectmanagement, dit betreft de algehele aansturing van het project incl. stuurgroep, werkgroep en stakeholdermanagement. 2. Onderzoeksactiviteiten, bestaande uit a) cross-chain-samenwerking, b) duurzaamheid en c) adoptie van digitale oplossingen voor datagedreven logistiek. 3. Management van een living lab, een ‘quadruple-helix-setting’ die fysieke en digitale leeromgevingen integreert voor onderwijs en multidisciplinair toegepast onderzoek.

The general aim of this research project has been to examine this phenomenon of tourism flow switching and consider the factors driving the geopolitical instability that can compromise destination security. On a more practical level the research has also examined what the reactions of Dutch tourists are to security threats affecting their tourism decisions and looked at the development of preventive measures against attacks by destinations and travel organisations. Finally, the research on the regional geopolitics of the MENA and European areas have together with the attitudes of Dutch tourists towards destination security been used as inputs into a scenario planning process involving the steering group of tour operators who originally commissioned this research, as participants. This process has focussed on macro environmental analysis, identification of key uncertainties, and the development of resilient strategies for the future.

This paper assesses wind resource characteristics and energy yield for micro wind turbines integrated on noise barriers. An experimental set-up with sonic anemometers placed on top of the barrier in reference positions is realized. The effect on wind speed magnitude, inflow angle and turbulence intensity is analysed. The annual energy yield of a micro wind turbine is estimated and compared using data from a micro-wind turbine wind tunnel experiment and field data. Electrical energy costs are discussed as well as structural integration cost reduction and the potential energy yield could decrease costs. It was found that instantaneous wind direction towards the barrier and the height of observation play an influential role for the results. Wind speed increases in perpendicular flows while decreases in parallel flow, by +35% down to −20% from the reference. The azimuth of the noise barrier expressed in wind field rotation angles was found to be influential resulted in 50%–130% changes with respect to annual energy yield. A micro wind turbine (0.375 kW) would produce between 100 and 600 kWh annually. Finally, cost analysis with cost reductions due to integration and the energy yield changes due to the barrier, show a LCOE reduction at 60%–90% of the reference value. https://doi.org/10.1016/j.jweia.2020.104206

From the article: The ethics guidelines put forward by the AI High Level Expert Group (AI-HLEG) present a list of seven key requirements that Human-centered, trustworthy AI systems should meet. These guidelines are useful for the evaluation of AI systems, but can be complemented by applied methods and tools for the development of trustworthy AI systems in practice. In this position paper we propose a framework for translating the AI-HLEG ethics guidelines into the specific context within which an AI system operates. This approach aligns well with a set of Agile principles commonly employed in software engineering. http://ceur-ws.org/Vol-2659/

In het winternummer van 2005, met het thema: Social Emergency and Crisis Intervention in Large European Cities, beschrijft Lia van Doorn de onderzoeksresultaten van een follow-up studie onder (voormalige) daklozen in Utrecht. Het betreft een kwalitatief onderzoek. In dit artikel worden drie fasen in het ontwikkelingsproces van de daklozen beschreven: Recente, langdurige en voormalige dakloosheid. De omstandigheden in deze fasen verschillen en daardoor ook de zorgbehoefte.

Emotions are a key component of tourism experiences, as emotions make experiences more valued and more memorable. Peak-and-end-theory states that overall experience evaluations are best predicted by the emotions at the most intense and final moments of an experience. Peak-and-end-theory has mostly been studied for relatively simple experiences. Recent insights suggest that peak-and-end-theory does not necessarily hold for tourism experiences, which tend to be more heterogeneous and multi-episodic in nature. Through the novel approach of using electrophysiological measures in combination with experience reconstruction, the applicability of the peak-and-end-theory to the field of tourism is addressed by studying a musical theatre show in a theme park resort. Findings indicate that for a multi-episodic tourism experience, hypotheses from the peak-and-end-theory are rejected for the experience as a whole, but supported for individual episodes within the experience. Furthermore, it is shown that electrophysiology sheds a new light on the temporal dynamics of experience

Experiences are at the core of tourism and hospitality. Understanding how to design, manage and measure such experiences has become a key topic in academic literature focused on this sector. This paper presents the characteristics of an optimal design process model for experiences, based on the results of a meta-ethnographic synthesis of such processes. The characteristics can be seen as critical success factors in delivering the right solution to the right problem efficiently and effectively. Depending on the context, starting level and aim of the design, designers can benefit from applying several different design processes. Such a process benefits from design capabilities developed in multi-disciplinary teams. Moreover, the design process aids design teams through steering the collection of explicit and tacit knowledge on problem and solution aspects with stakeholders in a specific order. The success of a design process depends on procedural knowledge of lead designers and their ability to orchestrate and integrate contributions from various disciplines and stakeholders at the right times. Existing design processes for tourism and hospitality experiences lack maturity and flexibility, resulting in them having poor structural validity. However these processes, with insights from design science, can form a base for further theoretical development.
