Most maritime products are typically associated with large investments and are seldom built in large series. Where other modes of transport benefit from the economy of series production, this is not the case for maritime products which are typically designed to refined customer requirements increasingly determined by the need for high efficiency, flexibility and low environmental impact at a competitive price. Product design is thus subject to global trade-offs among traditional constraints (customer needs, technical requirements, cost) and new requirements (life-cycle, environmental impact, rules). One of the most important design objectives is to minimise total cost over the economic life cycle of the product, taking into account maintenance, refitting, renewal, manning, recycling, environmental footprint, etc. The trade-off among all these requirements must be assessed and evaluated in the first steps of the design process on the basis of customer / owner specifications. Advanced product design needs to adapt to profound, sometimes contradicting requirements and assure a flexible and optimised performance over the entire life-cycle for varying operational conditions. This calls for greatly improved design tools including multi-objective optimisation and finally virtual testing of the overall design and its components. HOLISHIP (HOLIstic optimisation of SHIP design and operation for life-cycle) addresses these urgent industry needs by the development of innovative design methodologies, integrating design requirements (technical constraints, performance indicators, life-cycle cost, environmental impact) at an early design stage and for the entire life-cycle in an integrated design environment. Design integration will be implemented in practice by the development of integrated design s/w platforms and demonstrated by digital mock-ups and industry led application studies on the design and performance of ships, marine equipment and maritime assets in general.

EU ocean policies increasingly incorporate regional measures. Under the long standing Common Fisheries Policy, such measures aim at improving and reforming existing policy, either by taking into account region specific social or ecologic requirements or by establishing procedures and institutions to achieve a regional fit. By contrast, the EU's emerging integrated Marine Environmental Policy was designed to draw heavily on regional procedural and institutional mechanisms from the outset. The developing regional measures raise the question whether they contribute to improving institutional structures governing the use and conservation of EU waters. This article analyzes the existing and future regional measures of the two policies and their varying purposes and scopes. It develops a typology for categorizing the regional aspects and examines the effects of regional measures on EU institutions and the theoretical EU integration debate. © 2012 Elsevier Ltd.

Hemp is a sustainable high yielding crop well adapted to most European conditions, with advantageous environmental and agronomical characteristics. Traditionally cultivated for the fibres, seeds and psychoactive substances, it is now considered an ideal crop to produce innovative biomaterials. Once a key industrial crop for fibre, hemp production declined in the last century and was displaced by cotton and synthetic fibres. This explains why hemp has not been subject to the intensive breeding that has driven great improvements in major food crops in the last 50 years. However, cotton has one of the worst environmental footprints of any crop and there is renewed interest in hemp because it requires less water and agrochemicals and provides fibre and oil of superior quality. In the frame of multi-hemp, we will use cutting-edge genomic approaches to achieve rapid targeted improvements in hemp productivity and raw material quality for end-user requirements, whilst also advancing scientific understanding of gene-to-trait relationships in this crop. This work will be combined with innovations in agronomy, harvesting and processing methods to generate sustainable products from improved varieties. The project will include demonstration activities such as field trial and process scale up. The economic and environmental implications of each innovation will be assessed so as to maximise economic return and increase sustainability. This project brings together leading research groups with a vibrant group of industrial participants working from the level of molecular genetics through to end product demonstration. Our ambition is to develop an integrated hemp-based biorefinery in which improved feedstock is subject to efficient and modular processing steps to provide fibre, oil, construction materials, fine chemicals and biofuels using all components of the harvested biomass, and generating new opportunities within the developing knowledge based bioeconomy.

The Communitys maritime sector must sustain and improve its competitive advantage, with the groundwork for future international competitiveness resting with high quality and innovative education and training. Employees in the maritime transport sector need innovative educational opportunities that focus on their special working conditions. The KNow-ME project addresses this need by engendering a modern image of shipping which attracts young people to maritime careers at sea and ashore and instils an awareness of the industry as a driver of EU development and an attractive employer. This can only be achieved though critical dialogue with industry on potential future developments, current and future strengths and weaknesses, and the support required to ensure a forward thinking sustainable industry. The KNow-ME consortium argues that maritime training and education requires a life-cycle approach, where demand-oriented transnational e-courses and supporting material are developed in line with industry expectations and modern lifestyles. Enhanced education and training for the industrys professions must cater for a multicultural working environment, gender neutrality and maximum accessibility independent from time and space. A modern image, career management and e-training and education will be promoted by establishing an e-portal that integrates with other e-maritime initiative developments. Implementation of the proposed education and training strategies require the support of both industry and proactive national and regional policy and practices that enhance the transparency, transferability and compatibility of training and educations standards. The KNow-ME project will establish a network of excellence in Europe, integrating experience from leading maritime research institutions. The pilot applications of e-courses developed within KNow-ME will allow for CPD, with the outcomes expected to contribute to improved living and working conditions on board vessels.

Waste Management and Research | Year: 2012
Rapid economic growth and urbanization in developing countries lead to extensive construction activities that generate a large amount of waste. A challenge is how to manage construction waste in the most sustainable way. In the developing world, research on construction waste management is scarce and such academic knowledge needs to be responsive to actual practices in the industry in order to be implemented. As construction projects involve a number of participants and stakeholders, their participation and commitment can have a major influence on the goals of green and sustainable construction for urban development. This study provides a significant step in conducting a very first research of this kind in Thailand by aiming to investigate the level of construction stakeholders' commitment as well as the achievement of construction waste management in order to improve short-term practices and to establish a long-term strategic construction waste management plan. In this study, a structural equation model was employed to investigate the influence of factors that are related to environmental aspects, social aspects, and economic aspect of construction waste management. Concern about health and safety was found to be the most significant and dominant influence on the achievement of sustainable construction waste management. Other factors affecting the successful management of construction waste in Thai construction projects were also identified. It is perceived that this study has potential to contribute useful guidelines for practitioners both in Thailand and other developing countries with similar contexts. © The Author(s) 2012.

Composites Part A: Applied Science and Manufacturing | Year: 2011
Cellulose fibre-reinforced poly(lactic acid) (PLA) and poly(3- hydroxybutyrate) (PHB) composites have become increasingly interesting with regard to their biodegradability and mechanical characteristics. The use of different matrices leads to variable composite characteristics. This study provides a comparison of the mechanical characteristics of compression-moulded 30 mass% lyocell and 40 mass% kenaf fibre-reinforced PLA and PHB. The results of the tensile tests showed that 30 mass% lyocell/PLA composites reached the highest tensile and bending strength with 89 and 148 N/mm2, respectively. The highest Young's modulus was also measured for 30 mass% lyocell/PLA with 9.3 GPa, and the highest flexural modulus was measured for 40 mass% kenaf/PHB with 7.1 GPa. By far, the best impact strength was determined for lyocell/PHB with 70 kJ/m2, followed by lyocell/PLA with 52 kJ/m2. The investigation of the Shore D hardness resulted in a higher value for the PLA matrix with 81.5. PHB achieved a hardness of 67.5. By adding fibres as reinforcement, the Shore D hardness increased up to 83.6 for lyocell/PLA and 73.1 for kenaf/PHB. Density measurements showed lower densities for the composites with higher fibre loads (kenaf/PLA and kenaf/PHB) in comparison to the theoretical density. This speaks for a higher proportion of air inclusion in the composites which could negatively affect the mechanical composite characteristics. © 2011 Elsevier Ltd. All rights reserved.

Airport benchmarking has become a popular tool used by economists and airport managers alike. Within academic circles, a number of studies emerged assessing the productivity and efficiency of airports. This paper surveys the methods, data, and findings of empirical research in order to learn from previous research, and to gain further understanding of the airport industry. Our survey reveals that while commercialisation and restructuring contributed to efficiency increases, findings on ownership and scale effects are inconsistent. Data availability generally proved to be a serious issue. However, substantial progresses in capturing the increasing heterogeneous character of airports were made over time.

This paper explores coordination and cooperation between different levels of governance in the EU Marine Strategy Framework Directive and the US National Ocean Policy. Both policies aim at overcoming the previous sectoral organization of the marine policy field by establishing integrated approaches. As in the EU and the US, competencies in marine policies are shared between different levels of governance, the proper implementation of the Marine Strategy Framework Directive and the National Ocean Policy to large parts depends on the common efforts of all levels involved. In this submission, the co-management approach is used to analyze the coordinative procedures throughout the policy processes in the EU and the US. It derives four criteria for effective shared management from the literature, which are then applied to the Marine Strategy Framework Directive and the National Ocean Policy. It appears that the EU and the US promote different consensus-oriented procedures: while in the EU, they are mainly part of the decision-making phase, in the US, they are mostly subsequent to the National Ocean Policy's adoption. © 2014 Elsevier Ltd.

In a recently published paper (Abuelma'atti, Analog Integr Circuits Signal Process 65:419-428, 2010) the start-up conditions for a class of sinusoidal RC oscillators are discussed. In this context, the validity of the well known Barkhausen condition for oscillation is challenged. In this comment some of the author's conclusions are critically reviewed and the applicability of the Barkhausen criterion is demonstrated. © 2011 Springer Science+Business Media, LLC.

A recently published paper (Singh, Analog Integr Circuit Signal Process, 62:327-332, 2010) dealing with the relationship between the Barkhausen condition for oscillation and the well known Nyquist stability criterion for systems with feedback is highly appreciated. However, it seems to be necessary to place some comments on it. The circuit examples presented in the cited paper as well as the conclusions will be critically reviewed. Apparently, there is still no sufficient oscillation condition. Therefore, the necessity to complete the existing oscillation criterion with a sufficient condition is emphasized. © 2010 Springer Science+Business Media, LLC.
