Paris Charles de Gaulle Airport was the second European airport in terms of traffic in 2019, having transported 76.2 million passengers. Its large infrastructures include four runways, a large taxiway network, and 298 aircraft parking stands (131 contact) among three terminals. With the current pandemic in place, the European air traffic network has declined by −65% flights when compared with 2019 traffic (pre-COVID-19), having a severe negative impact on the aviation industry. More and more often taxiways and runways are used as parking spaces for aircraft as consequence of the drastic decrease in air traffic. Furthermore, due to safety reasons, passenger terminals at many airports have been partially closed. In this work we want to study the effect of the reduction in the physical facilities at airports on airspace and airport capacity, especially in the Terminal Manoeuvring Area (TMA) airspace, and in the airport ground side. We have developed a methodology that considers rare events such as the current pandemic, and evaluates reduced access to airport facilities, considers air traffic management restrictions and evaluates the capacity of airport ground side and airspace. We built scenarios based on real public information on the current use of the airport facilities of Paris Charles de Gaulle Airport and conducted different experiments based on current and hypothetical traffic recovery scenarios. An already known optimization metaheuristic was implemented for optimizing the traffic with the aim of avoiding airspace conflicts and avoiding capacity overloads on the ground side. The results show that the main bottleneck of the system is the terminal capacity, as it starts to become congested even at low traffic (35% of 2019 traffic). When the traffic starts to increase, a ground delay strategy is effective for mitigating airspace conflicts; however, it reveals the need for additional runways
Renewable energy sources have an intermittent character that does not necessarily match energy demand. Such imbalances tend to increase system cost as they require mitigation measures and this is undesirable when available resources should be focused on increasing renewable energy supply. Matching supply and demand should therefore be inherent to early stages of system design, to avoid mismatch costs to the greatest extent possible and we need guidelines for that. This paper delivers such guidelines by exploring design of hybrid wind and solar energy and unusual large solar installation angles. The hybrid wind and solar energy supply and energy demand is studied with an analytical analysis of average monthly energy yields in The Netherlands, Spain and Britain, capacity factor statistics and a dynamic energy supply simulation. The analytical focus in this paper differs from that found in literature, where analyses entirely rely on simulations. Additionally, the seasonal energy yield profile of solar energy at large installation angles is studied with the web application PVGIS and an hourly simulation of the energy yield, based on the Perez model. In Europe, the energy yield of solar PV peaks during the summer months and the energy yield of wind turbines is highest during the winter months. As a consequence, three basic hybrid supply profiles, based on three different mix ratios of wind to solar PV, can be differentiated: a heating profile with high monthly energy yield during the winter months, a flat or baseload profile and a cooling profile with high monthly energy yield during the summer months. It is shown that the baseload profile in The Netherlands is achieved at a ratio of wind to solar energy yield and power of respectively Ew/Es = 1.7 and Pw/Ps = 0.6. The baseload ratio for Spain and Britain is comparable because of similar seasonal weather patterns, so that this baseload ratio is likely comparable for other European countries too. In addition to the seasonal benefits, the hybrid mix is also ideal for the short-term as wind and solar PV adds up to a total that has fewer energy supply flaws and peaks than with each energy source individually and it is shown that they are seldom (3%) both at rated power. This allows them to share one cable, allowing “cable pooling”, with curtailment to -for example-manage cable capacity. A dynamic simulation with the baseload mix supply and a flat demand reveals that a 100% and 75% yearly energy match cause a curtailment loss of respectively 6% and 1%. Curtailment losses of the baseload mix are thereby shown to be small. Tuning of the energy supply of solar panels separately is also possible. Compared to standard 40◦ slope in The Netherlands, facade panels have smaller yield during the summer months, but almost equal yield during the rest of the year, so that the total yield adds up to 72% of standard 40◦ slope panels. Additionally, an hourly energy yield simulation reveals that: façade (90◦) and 60◦ slope panels with an inverter rated at respectively 50% and 65% Wp, produce 95% of the maximum energy yield at that slope. The flatter seasonal yield profile of “large slope panels” together with decreased peak power fits Dutch demand and grid capacity more effectively.
The purpose of this study was to analyse knowledge management research trends to understand the development of the field using a combination of scientometric, bibliometric, and visualisation techniques, subsequently developing a normative framework of knowledge management from the results.282 articles between the years 2010–2015 were retrieved, analysed, and visualised to produce the state of knowledge management during the selected timeframe. The results of this study provide a visualisation of the current research trends to understand the development of the knowledge management discipline. There are signals that the literature about knowledge management is progressing towards academic maturity. This study is one of the first studies to combine bibliometric and scientometric methods to assess productivity along with visualisation, and subsequently provide a knowledge management framework drawing from the results of these methods.

Client: Foundation Innovation Alliance (SIA - Stichting Innovatie Alliantie) with funding from the ministry of Education, Culture and Science (OCW) Funder: RAAK (Regional Attention and Action for Knowledge circulation) The RAAK scheme is managed by the Foundation Innovation Alliance (SIA - Stichting Innovatie Alliantie) with funding from the ministry of Education, Culture and Science (OCW). Early 2013 the Centre for Sustainable Tourism and Transport started work on the RAAK-MKB project ‘Carbon management for tour operators’ (CARMATOP). Besides NHTV, eleven Dutch SME tour operators, ANVR, HZ University of Applied Sciences, Climate Neutral Group and ECEAT initially joined this 2-year project. The consortium was later extended with IT-partner iBuildings and five more tour operators. The project goal of CARMATOP was to develop and test new knowledge about the measurement of tour package carbon footprints and translate this into a simple application which allows tour operators to integrate carbon management into their daily operations. By doing this Dutch tour operators are international frontrunners.Why address the carbon footprint of tour packages?Global tourism contribution to man-made CO2 emissions is around 5%, and all scenarios point towards rapid growth of tourism emissions, whereas a reverse development is required in order to prevent climate change exceeding ‘acceptable’ boundaries. Tour packages have a high long-haul and aviation content, and the increase of this type of travel is a major factor in tourism emission growth. Dutch tour operators recognise their responsibility, and feel the need to engage in carbon management.What is Carbon management?Carbon management is the strategic management of emissions in one’s business. This is becoming more important for businesses, also in tourism, because of several economical, societal and political developments. For tour operators some of the most important factors asking for action are increasing energy costs, international aviation policy, pressure from society to become greener, increasing demand for green trips, and the wish to obtain a green image and become a frontrunner among consumers and colleagues in doing so.NetworkProject management was in the hands of the Centre for Sustainable Tourism and Transport (CSTT) of NHTV Breda University of Applied Sciences. CSTT has 10 years’ experience in measuring tourism emissions and developing strategies to mitigate emissions, and enjoys an international reputation in this field. The ICT Associate Professorship of HZ University of Applied Sciences has longstanding expertise in linking varying databases of different organisations. Its key role in CARMATOP was to create the semantic wiki for the carbon calculator, which links touroperator input with all necessary databases on carbon emissions. Web developer ibuildings created the Graphical User Interface; the front end of the semantic wiki. ANVR, the Dutch Association of Travel Agents and Tour operators, represents 180 tour operators and 1500 retail agencies in the Netherlands, and requires all its members to meet a minimum of sustainable practices through a number of criteria. ANVR’s role was in dissemination, networking and ensuring CARMATOP products will last. Climate Neutral Group’s experience with sustainable entrepreneurship and knowledge about carbon footprint (mitigation), and ECEAT’s broad sustainable tourism network, provided further essential inputs for CARMATOP. Finally, most of the eleven tour operators are sustainable tourism frontrunners in the Netherlands, and are the driving forces behind this project.

KnowledgeFlows in Marine Spatial Planning - Sharing Innovation in Higher Education(KnowledgeFlows) aims at further enforcing the European higher education community to meet the growing demands for knowledge, skills and innovation within the still emerging field of marine or maritime spatial planning (MSP).Marine Spatial Planning (MSP) is an emerging governmental approach towards a more effective use of the sea. MSP is of great interest in Europe and can be considered a societal process to balance conflicting interests of maritime stakeholders and the marine environment. Many different activities take place at sea, ranging from shipping, fisheries, to offshore wind energy activities. Simultaneously, new and evolving policies focus on strategies to integrate different marine demands in space and resources. MSP is now legally binding in the EU and is much needed approach to manage and organize the use of the sea, while also protecting the environment.KnowledgeFlows will contribute to the development of new innovative approaches to higher education and training on MSP by means of problem-based learning schemes, transdisciplinary collaboration, and advanced e-learning concepts. KnowledgeFlows builds on results from former project outputs (Erasmus+ Strategic Partnership for Marine Spatial Planning SP-MSP), such as the online learning platform MSP Education Arena (https://www.sp-msp.uol.de).The strategic partnership consists of a transnational network of experts both in research and in practice based in the north Atlantic, Baltic Sea and North Sea Regions including Aalborg University (DK, lead partner), The University of Oldenburg (D), the University of Liverpool (U.K.), the University of Nantes (F), the Leibniz Institute for Baltic Sea Research (D), the Breda University of Applied Sciences (NL), University of Ulster (U.K.), and the Finnish Environment Institute (FI). Gothenburg University, also being a higher education organisation, will be associated partner.Furthermore, three international organisations, the Marine Spatial Planning Research Network, the Baltic inter-governmental VASAB and the pan-Nordic Nordregio will be involved in the partnership as associated organisations deeply rooted in the MSP community of practice.The further improvement of curricula, exchange of knowledge and experts, and transparency and recognition of learning outcomes to reach higher qualifications in MSP are key components of KnowledgeFlows. A mutual learning environment for MSP higher education will enable problem-driven innovation among students and their educators from research and governance also involving stakeholders. Related activities on intellectual outputs, multiplier events and lecturing will be carried out by all participating organisations.The intellectual outputs are related to three major contributions to the European higher education landscape:1) an advanced level international topical MSP course (Step-up MSP)2) digital learning facilities and tools (MSP Education Arena)3) designing problem-based learning in MSP (MSP directory)The advanced level inter-institutional topical MSP course will include different teaching and training activities within a problem-based learning environment. Digital learning facilities enabling communication and training will include a further enrichment of the MSP Education Arena platform for students, practitioners and lecturers for including modules forcollaborate learning activities, documentation and dissemination, mobilisation/recruitment, thesis opportunities, placements/internships. Designing problem-based learning in MSP will include topics as; the design of didactics and methods; guidance for lecturers, supervisors and students; evaluation and quality assurance; assessment.Five multiplier events back to back or as part of conferences within the MSP community will be organised to mainstream the outputs and innovative MSP didactics among other universities and institutions.Different teaching and training activities feeds into the intellectual output activities, which will include serious gaming sessions (MSP Challenge (http://www.mspchallenge.info/) and others), workshops, excursions, courses/classes as well as a conference with a specific focus on facilitating the exchange of innovative ideas and approaches among students at bachelor´s, master´s and doctoral level and the MSP community of practice.Project management meetings (twice a year) will assure coherence in project planning and implementation. As the core focus of the strategic partnership is on collaboration, mutual learning, and innovation among educators, students, and practitioners in order to meet actual and future needs regarding knowledge exchange and training within the MSP community, the project will be designed to have long lasting effects.Results
