Port Cities can be seen as multidimensional laboratories where challenges connected with urban mobility are more complex due to the dual system of gravity centre: the city, the port, not to mention their shared hinterland.These peculiarities are at once a challenge and an opportunity, as they provide scope for planning, researching and implementing integrated mobility solutions in distinctively complex urban contexts. Civitas PORTIS designs, demonstrates and evaluates integrated sets of sustainable mobility measures in 5 major port cities located on the North Sea (Aberdeen and Antwerp), the Mediterranean Sea (Trieste), the Black Sea (Constanta), and Baltic Sea (Klaipeda). The project also involves a major international follower port city on the East China Sea (Ningbo). Thanks to the Civitas Initiative, the partner cities expect to prove that more efficient and sustainable mobility is conducive to the establishment of vital and multi-modal hubs for urban, regional, national and International movements of passengers and goods. To do this, they establish integrated living laboratories clustering local measures according to four major aspects of sustainable urban mobility: 1. Governance: to increase port-city collaborative planning and participation, leading to enhanced forms of SUMPs. 2. People: to foster less car-dependent mobility styles, leading to modal shift in favour of collective and more active transport. 3. Transport system: to strengthen the efficiency of road traffic management to/from the port and through the city, and foster the use of clean vehicles. 4. Goods: to enhance logistics and freight transport, improving the efficiency and coordination of city, port and regional freight movements. Working with port cities, Civitas PORTIS will generate a strong and twofold replication potential: 1) specifically to other port cities, and 2) more generally to cities presenting major transport nodes and attractors for the benefit of the whole CIVITAS Initiative.

China is already an important global actor in the fields of research and innovation, and has the potential of becoming a leading force in the next few decades. The shift in Chinas strategy focusing towards R&I and transforming the essence of its economy has been complimented with massive public investments in research and technology. The EU having recognised the leading role China is expected to play, and having adopted a strategic position for becoming a knowledge-based economy, is required to collaborate with China in areas of mutual interest, and for common benefit and prosperity. Moreover for critical global issues which demand close scientific and technological cooperation at an international level, EU has identified in China a natural partner able to contribute and complement its own capacity. The proposed initiative aims to provide support services to European and Chinese researchers, and a flexible platform to facilitate policy discussions between European and Chinese stakeholders. Moreover, DRAGON-STARPLUS will provide the EC and the Member States with a toolset for setting a long term cooperation strategy in research and innovation with China. The project aims to provide efficient services on three levels (priority areas): - Support the European and Chinese research communities to establish collaborations under Horizon 2020 and beyond. -Provide a cooperation platform and tools to policy makers, aiming ultimately to support and enhance the bilateral cooperation, through the concept of mutual benefit. -Provide an ERA-NET style platform to funding agencies for exchanging best practices and planning joint activities. The proposed activities take into account the current on-going policy dialogue and the peculiarities of the research and innovation environment in China, and are based upon the outputs and the established mechanisms of the previous DRAGON-STAR project, as well as upon the sound results of previous related projects (e.g. OPEN-ICT, CO-REACH).

Building and Environment | Year: 2014
Buildings are huge energy consumers and are responsible for a large part of greenhouse gas emissions in the world. Among building energy efficiency measures, solar shading plays a significant role in reducing building energy consumption, especially in hot summer and cold winter zone of China. This paper carried out a field measurement of shading performance of movable shades installed on the south-facing facade of a residential building in Ningbo city of China. The field tests show that external movable solar shades have a good shading performance that can reduce solar transmittance to about 8% and keep indoor illuminance at about 1000lux with little fluctuations, indicating a suitable level for indoor environments. A building simulation study on energy, indoor thermal and visual performance of movable solar shades was further carried out. Several important indexes were adopted to give an in-depth analysis, including energy performance, room base temperature, transmitted solar radiation, PMV-PPD and its distribution as well as Discomfort Glare Index (DGI). Results show that movable solar shades used for south-facing windows not only reduce building energy demand by 30.87%, but also improve indoor thermal comfort by 21% in summer as well as reduce dramatically extremely uncomfortable risks by 80.4%, and meanwhile the visual comfort condition is also improved by 19.9%.© 2013 Elsevier Ltd.

Nonlinear Dynamics | Year: 2013
With the help of the similarity transformation connected the variable-coefficient nonlinear Schrödinger equation with the standard nonlinear Schrödinger equation, we firstly obtain first-order and second-order rogue wave solutions in two dimensional graded-index waveguides. Then, we investigate the nonlinear tunneling of controllable rogue waves when they pass through nonlinear barrier and nonlinear well. Our results indicate that the propagation behaviors of rogue waves, such as postpone, sustainment and restraint, can be manipulated by choosing the relation between the maximum value of the effective propagation distance Z m and the effective propagation distance corresponding to maximum amplitude of rogue waves Z 0. Postponed, sustained and restrained rogue waves can tunnel through the nonlinear barrier or well with increasing, unchanged and decreasing amplitudes by modulating the ratio of the amplitudes of rogue waves to barrier or well height. © 2013 Springer Science+Business Media Dordrecht.

Applied Energy | Year: 2012
Current energy designs for a building in China focus on the energy efficiency of the whole building and thus often neglect the energy difference between different housing units in apartment buildings. The best design technique in terms of energy savings is not only to decrease whole building energy demand, but also to reduce the energy difference between different housing units to a relatively low level. This paper introduces an important index "energy performance difference between housing units" (EDH) to evaluate the drawbacks of conventional designs on a typical residential building in hot summer and cold winter zone. Then nine improved design options were considered as the possible strategies to diminish the EDH, based on a number of building simulations with the program DeST-h. Results show that the option 9 (add movable shading for the east facing windows and west facing windows, and reduce the U-values of the east walls and west facing windows), an improved design strategy according to the EDH of the current design, reduces the EDH to less than 4% that is much lower than other options and meanwhile ensures a decrease in whole building energy demands. A case study was carried out to validate the effectiveness of this index in optimization. As a conclusion, EDH is a very useful index for optimizing energy designs of apartment buildings and can be used in China to improve conventional building designs. © 2012 Elsevier Ltd.
