Physical wave basin tests with a focus on uncertainty estimation have been conducted on a fixed sphere subjected to wave loads at Aalborg University as part of the effort of the OES Wave Energy Converters Modeling Verification and Validation (formerly, OES Task 10) working group to increase credibility of numerical modeling of WECs.
The present note defines an idealized test case formulated to accurately represent the physical tests in a simple way. The test case consists of a fixed, rigid sphere half submerged in water subjected to regular waves of three different levels of linearity. The objective of the present note is to allow for numerical tests of the idealized test case.
Most regulatory tools for low-carbon transition are jurisdiction-specific, respecting the principle of national sovereignty. Although possibly locally successful, they typically capture only scope 1 and scope 2 emissions. Value chains-related (scope 3) emissions remain largely unregulated. This is problematic, as global value chains are commonly organized across multiple jurisdictions with different climate policy ambitions. Products are often produced at different location than where they are consumed, and production-related emissions are transferred with the products. These emissions embedded in imported products amount to large volumes (e.g. in the EU estimated to about 30% of member state’s national emissions). This chapter gathers the scientific evidence on upstream scope 3 emissions and discusses the available regulatory toolbox for reducing those. Both private and public regulatory tools are represented as well as soft and hard regulatory tools, and modifications between those categories. The interactions between the various types of regulation are discussed with the aim to identify possible synergies and conflicts. The chapter takes the EU as its starting point and draws in examples from other jurisdictions where relevant.
This report presents the AEGIS roadmap for automated waterborne transport and is the result of the work related to Task 2.5 Roadmap for waterborne logistics redesign as defined in the AEGIS Grant Agreement. The task was to collect the results of the AEGIS work package 2 and 6, and the AEGIS use cases, to provide a publicly available roadmap for the redesign of more sustainable waterborne transport. Furthermore, the main AEGIS solutions that can be used to realize the redesign were to be identified, and benefits and possible costs were to be described, exemplified by future transport systems, including intercontinental transport. Furthermore, the focus was to be on unitized cargo (ie, containers and ro-ro trailers).
The report is based on the AEGIS use cases and outlines one logistics redesign for short sea shipping where the cargo is containers, and one for inland waterways shipping where the cargo is roro trailers. Intercontinental transport was not studied in detail within the AEGIS project, as it was not in scope. This means that no study investigating the applicability of AEGIS solutions for intercontinental transport has been done, and thus the background for creating a roadmap for intercontinental transport is missing. Instead, intercontinental transport is briefly discussed in a separate section of the report. Furthermore, even though the AEGIS solutions do not target the deep sea leg of intercontinental transport, they are highly applicable to the distribution and consolidation of cargo in the hinterland. For this part of intercontinental transport, the short sea and inland transport roadmaps are directly applicable.
For each of the two segments short sea and inland waterways, the bassline "as-is" scenarios are discussed to provide insight into current challenges and areas with potential for improvements. Then a redesign is introduced, where the AEGIS innovations and concepts are used to gain efficiency benefits and zero emission transport systems. As part of the redesign discussion, the gaps towards realization are also discussed and identified. These are related to immature technology, certain issues that are currently not addressed and need both research and development, and issues related to uptake and investment risk. Next, one roadmap for short sea shipping and one for inland waterways is presented, and discussed in terms of short term, medium term and long term phases and what advancements need to be made (ie, what gaps need to be closed) within each of these periods. Finally, policy support and actions are discussed in terms of what will be required to realize the roadmaps.
The two roadmaps presented in this report include discussions for the short-, medium- and long-term periods. The roadmaps are structured this way to facilitate a discussion around which aspects are mature, and which require more research and has a longer expected horizon to market. The roadmaps are written with the purpose of allowing the implementation of the new transport systems in the short, medium and long term, and a discussion is made around the sustainability of the transport system at each maturity level.
The project "IEA OES Task 10 Phase III - WEC Modelling" is a publicly-funded research project under the Danish Energy Agency EUDP grant with Journal no. 134232-510153. As part of the initial period of the project, a selection of three test cases has been defined under WP2. The present report forms the deliverable for Milestone "M1: Case studies defined".
Studies have indicated that transportation noise is associated with higher cardiovascular mortality, whereas evidence of noise as a risk factor for respiratory and cancer mortality is scarce and inconclusive. Also, knowledge on effects of low-level noise on mortality is very limited. We aimed to investigate associations between road and railway noise and natural-cause and cause-specific mortality in the Danish population. We estimated address-specific road and railway noise at the most (LdenMax) and least (LdenMin) exposed façades for all residential addresses in Denmark from 1990 to 2017 using high-quality exposure models. Using these data, we calculated 10-year time-weighted mean noise exposure for 2.6 million Danes aged >50 years, of whom 600,492 died from natural causes during a mean follow-up of 11.7 years. We analyzed data using Cox proportional hazards models with adjustment for individual and area-level sociodemographic variables and air pollution (PM2.5 and NO2). We found that a 10-year mean exposure to road LdenMax and road LdenMin per 10 dB were associated with hazard ratios (95% confidence intervals) of, respectively, 1.09 (1.09; 1.10) and 1.10 (1.10; 1.11) for natural-cause mortality, 1.09 (1.08; 1.10) and 1.09 (1.08; 1.10) for cardiovascular mortality, 1.13 (1.12; 1.14) and 1.17 (1.16; 1.19) for respiratory mortality and 1.03 (1.02; 1.03) and 1.06 (1.05; 1.07) for cancer mortality. For LdenMax, the associations followed linear exposure-response relationships from 35 dB to 60–<65 dB, after which the function levelled off. For LdenMin, exposure-response relationships were linear from 35 dB and up, with some levelling off at high noise levels for natural-cause and cardiovascular mortality. Railway noise did not seem associated with higher mortality in an exposure-response dependent manner. In conclusion, road traffic noise was associated with higher mortality and the increase in risk started well below the current World Health Organization guideline limit for road traffic noise of 53 dB.
Once known as an example of state collapse, Somali territories today see a number of competing public administrations, which, as this book argues, depend on a dynamic trade sector for revenues. Riffing on Tilly’s idea that ‘war makes states,’ the authors argue instead that ‘trade makes states,’ that the facilitation and capture of commodity flows have been instrumental in making and unmaking state-projects across the Somali territories. The volume draws on multi-sited research of everyday economic life along trade corridors in Somali East Africa, including parts of Kenya and Ethiopia. It examines how government officials, informal traders, militias, local businessmen, international investors, and donors feed into systems of regulatory control in ports, at marketplaces, and along transport corridors. Contributions to the volume draw attention to the ingenuities of transnational Somali trade and the ‘politics of circulation,’ providing important insights into contemporary state formation on the margins of global supply chain capitalism.
Capacitors are fundamental electronic passive components and there are nearly everywhere. There are many different capacitors technologies, with different dielectric materials, form factors and terminals and housings available. This short encyclopedic article discuss the main capacitor types which are relevant for power electronic applications. The main types are Aluminum Electrolytic Capacitors, Metallized Film Capacitor, Ceramic Capacitors and Supercapacitors. The principal construction, materials and properties and technological limitations are discussed. Further new upcoming trends of new materials and designs are presented.
The 1982 United Nations Convention on the Law of the Sea (UNCLOS) has for four decades been considered by many to be one of the most important legislative achievements of international law. It is revered as a “constitution of the oceans”, providing the legal framework for the governance of the oceans. This volume explores how the UNCLOS is functioning in various complex settings, how it adapts to new, emerging developments, as well as how it interacts with other regulations, both within the law of the sea regime and outside. Engaging in themes such as law and order at sea, UNCLOS' interaction with human rights and the role of private actors, the book raises complex questions in the application, understanding, and enforcement of the convention and how it can be envisaged, interpreted, and used in a dynamic world. The volume also raises methodological questions, the answers to which may enhance the predictability and coherence of the law under UNCLOS and thus secure its role as the predominant and relevant system for legal governance at sea for many decades to come. As a contribution to ensuring the future relevance of UNCLOS, the book will be a valuable resource for scholars, diplomats, judges and other practitioners who are working with and interpreting the law of the sea and related issues of maritime law, migration law, human rights law and humanitarian law.
As a reaction to an increasing concern with the decreasing of standards in shipping during the 1970s and 1980s the International Maritime Organization adopted the ISM Code, which became mandatory in 1998. This study revisits the ISM Code, firstly exploring the genesis of the code at the international level, and then its operationalization at the national and local level. Based on a three-step case study, the interplay between the essence of the ISM Code and praxis onboard is explored. The study explores the distortion and erosion of the essence of the ISM Code when implemented on the national level in Danish law (step one) and by two Danishbased companies (step two) and finally investigates the local effect of the code as it is displayed onboard (step three).
The study is conducted as an applied socio-legal study; thus, it adopts both an internal (doctrinal) and an external (empirical) approach. It also combines the topdown and bottom-up perspective, consequently applying different methods to fit the content of the different levels examined, while maintaining a qualitative approach.
The research design is inspired by the hermeneutic circle. The first circle (Part I the international level) explores the genesis of the ISM Code, aim to explore the causal explanation for and to determine the essence of the ISM Code. The ‘essence’ is constituted by the ‘principles’ that the regulators intended to be essential to achieve ‘the purpose’. With Santos’s cartographic metaphor as a theoretical analytical framework combined with legal dogmatic method, the first part concentrates on small-scale legality (the international level). The second circle (Part II) is related to medium-scale legality (the national/transnational level). Part II explore the operationalisation of the ISM Code as it is implemented in Danish law, applying legal dogmatic method, combined with analyses of written formal communication to identify the inter-legality that distort the principles when implemented at a national level (step one and two). The third circle (Part III) relates to large-scale legality, applying Goffman’s theoretical framework to analyse the micro level, that constitute the onboard praxis. Praxis is compared with legislation, v revealing a frontstage behaviour that is compliant with regulation and documented by checklists, while in fact praxis deviate, ‘to make it work’ the crew exhibits what Goffman denoted a backstage behaviour.
The ISM Code introduces meta-regulation as a regulatory mechanism. Metaregulation is linked to Santos’s concept of globalization and governance matrix; the study applies Parker’s definition of meta-regulation and the triple loop to study the concept.
The study identifies three principles that constitute the essence of the ISM Code; (1) to establish a genuine link between the company and the flag State; (2) to ensure that the company becomes responsible for the ship’s operation; and (3) to empower the master, ensuring her or his authority. The analyses proved that each of the three principals were distorted at respectively meso and micro level, and that even though the intent was to promote good ship management, in reality it has provided companies the opportunity strut in borrowed plumes.
This report discusses the concept of governance, how to understand 'effective' governance, and a research plan for further studies of the effectiveness of and potential for improving governance at the regional and sub-regional level in the SEAwise regions (Baltic Sea, North Sea, Western Waters, and the Mediterranean Sea). The theoretical insights from the first two main parts inform and are merged into the research plan, forming the last part of the report. The work is based on the recognition that fisheries management in Europe is still struggling to deliver on its objectives relating to ecology, economy, and social considerations although improvements have been made over the last decades. On top of this, marine biodiversity and ecosystem integrity can be identified as pressing challenges, while climate change presents renewed uncertainties and risks.
Improved governance, appropriately designed for Ecosystem Based Fisheries Management (EBFM), is key to improving the system performance towards the societal objectives. Lack of appropriate measures towards cooperation between the EU, national, and regional levels has led to uncoordinated decision-making processes and prevented coherent management through the implementation and adoption of EU legislation, leading to lower than desired performance both of fisheries and environmental policies. Referring specifically to the involvement of stakeholders, the European Commission stresses the importance of transparency, cooperation, outreach, information, and inclusiveness in developing and implementing measures to ensure that all stakeholders, not least fishermen, have a say in the management process, and that their needs and concerns are considered (European Commission, 2023a). Improvement of what can broadly be defined as 'governance' is, thus, among the pathways that the European Commission has identified for improvements in the area.
