As every new generation of civil aircraft creates more on-wing data and fleets gradually become more connected with the ground, an increased number of opportunities can be identified for more effective Maintenance, Repair and Overhaul (MRO) operations. Data are becoming a valuable asset for aircraft operators. Sensors measure and record thousands of parameters in increased sampling rates. However, data do not serve any purpose per se. It is the analysis that unleashes their value. Data analytics methods can be simple, making use of visualizations, or more complex, with the use of sophisticated statistics and Artificial Intelligence algorithms. Every problem needs to be approached with the most suitable and less complex method. In MRO operations, two major categories of on-wing data analytics problems can be identified. The first one requires the identification of patterns, which enable the classification and optimization of different maintenance and overhaul processes. The second category of problems requires the identification of rare events, such as the unexpected failure of parts. This cluster of problems relies on the detection of meaningful outliers in large data sets. Different Machine Learning methods can be suggested here, such as Isolation Forest and Logistic Regression. In general, the use of data analytics for maintenance or failure prediction is a scientific field with a great potentiality. Due to its complex nature, the opportunities for aviation Data Analytics in MRO operations are numerous. As MRO services focus increasingly in long term contracts, maintenance organizations with the right forecasting methods will have an advantage. Data accessibility and data quality are two key-factors. At the same time, numerous technical developments related to data transfer and data processing can be promising for the future.
All Gone is a series of experiments with AI that build on existing collections of climate fiction to create much-needed new climate imaginaries. As the climate crisis is also a “crisis of imagination” (Ghosh, 2016), this project turns to the art genre that is best at forecasting and imagining alternative futures: science fiction. Using collections of ‘cli-fi’ novels, in which science fiction meets natural disaster or heavy weather, algorithms are trained until they are able to render new climate imaginaries in textual and visual form. The edited texts and curated images are further developed into audio stories and a tarot deck as tools for reflection on present and future living with a changing climate.

Extant research on the role of weather in COVID-19 has produced ambiguous results and much methodological debate. Following advice emerging from this methodological debate, we take a step further in modeling effects of weather on COVID-19 spread by including interactions between weather, behavior, baseline cases, and restrictions in our model. Our model was based on secondary infection, hospitalization, restriction, weather, and mobility data per day nested with safety region in the Netherlands. Our findings show significant but inconsistent interactions. The robust effects of weather on COVID-19 spread persisted over and above these interactions, highlighting the need to account for weather with nuance and caution in public policy, communication, and forecasting

Since March 2013, Paul Peeters is a member of the ICAO/CAEP Working Group 3, which is responsible for setting a new fuel efficiency standard for of civil aviation. He does so for the International Coalition for Sustainable Aviation (ICSA). ICSA was established in 1998 by a group of national and international environmental NGOs as official observers. Since its inception, ICSA has contributed to CAEP’s work on technical means to reduce emissions and noise, the role of market-based measures, supporting economic and environmental analysis, modelling and forecasting, and ICAO’s carbon calculator. It has also been invited to present its views at ICAO workshops on carbon markets and bio-fuels, and has presented to the high-level Group on Internation Aviation and Climate Change (GIACC). ICSA uses the expertise within its NGO membership to formulate its co-ordinated positions. To gain the broadest level of understanding and input from environmental NGOs, ICSA communicates with, and invites comment from, other NGO networks and bodies working in related areas. ICSA’s participation in ICAO and CAEP meetings is currently provided by the Aviation Environment Federation (AEF), the International Council for Clean Transportation (ICCT) and Transport and Environment (T&E).

Een ziekenhuisopname voor een operatie heeft grote impact op kankerpatiënten. Ook als de ingreep medisch gezien goed is verlopen, leeft er bij patiënten vaak veel onzekerheid na ontslag uit het ziekenhuis. Dit komt door de complexiteit en veelheid aan behandelingen bij kanker en dit wordt extra versterkt als het ontslagproces sub-optimaal verloopt en niet aansluit bij de behoeften van patiënten. Dit is onwenselijk want het kan leiden tot vertraagd herstel, onnodige heropnames in het ziekenhuis (onnodige kosten) en stress en onzekerheid bij patiënten en hun naasten. Dit heeft een negatieve impact op het welzijn van mensen in hun leefomgeving en leidt tot een negatieve beleving van de zorgverlening. Zorgprofessionals weten echter niet wat mensen na een oncologische operatie nodig hebben om zich weer goed te voelen in hun leefomgeving en hoe zij daar vanuit de eerste en tweede lijn gezamenlijk aan kunnen bijdragen. Daarnaast is onbekend hoe zorgtechnologie zorgverleners en kankerpatiënten in hun leefomgeving daarbij kan ondersteunen. Het doel van dit onderzoek is het bevorderen van herstel en welzijn van mensen na een oncologische operatie en hun naasten, door kennisontwikkeling over hoe zorgprofessionals en ondersteuning middels technologie bij kunnen dragen aan een soepele overgang van ziekenhuis naar leefomgeving. Als uitgangpunt wordt de kennis en kunde uit het hotelvak gebruikt waar het uitchecken (ontslagprocedure) geperfectioneerd is en bijdraagt aan de goede waardering van het hotelbezoek. Om dit te realiseren is het onderzoek verdeeld in twee fasen: 1. Op basis van onderzoek naar de wensen en behoeften van kankerpatiënten en hun naasten, alsmede de ervaring van zorgprofessionals, wordt het ontslagproces herzien. 2. Er wordt onderzocht op welke wijze technologische ontwikkelingen (zoals zelfmonitoring) kunnen bijdragen aan het herstel van kankerpatiënten in de eigen leefomgeving.
