1、These patterns are important because many ecosystem services require landscape scale policy interventions, yet policies traditionally target only individual farmers (thus delivering field scale or farm scale interventions). These patterns are also important because they provide a proxy indicator for
2、 (the strength of) existing neighbourhood networks, through which policies can be communicated more effectively and farmers can be enticed to join more quickly (thus making the policy more efficient). Case study application identifies spatio-temporal patterns of uptake in different parts of Scotland
3、. Much stronger patterns are found in mountainous areas and on small islands, which is consistent with the expectation of stronger communities of place and neighbourhood networks in more remote places.103Technology-based design and scaling for RTGs for space exploration in the 100W rangeOriginal Res

5、ences AbstractThis paper presents the results of a study on design considerations for a 100W radioisotope thermo-electric generator (RTG). Special emphasis has been put on designing a modular, multi-purpose system with high overall TRL levels and making full use of the extensive Russian heritage in
6、the design of radioisotope power systems. The modular approach allowed insight into the scaling of such RTGs covering the electric power range from 50 to 200We (EoL). The retained concept is based on a modular thermal block structure, a radiative inner-RTG heat transfer and using a two-stage thermo-

11、g on the inspirational stage of design. The paper describes a semantic-based image retrieval tool developed for the needs of concept cars designers from two renowned European companies. It is created to help them find and interpret sources of inspiration. The core innovation of the tool is its abili
12、ty to provide a degree of diversity, ambiguity and uncertainty in the information gathering and idea generation process. The tool is based on the assumption that there is a semantic link between the images in a web page and the text around them. Furthermore, it uses the idea that the more frequently
13、 a term occurs in a document and the fewer documents it occurs in, the more representative this term is of that document. The new contribution is linking the most meaningful words in a document with ontological concepts, and then finding the most powerful set of concepts representing that document a
14、nd consequently the images in it. This is based on the observation that monosemic words (with a single meaning) are more domain-oriented than polysemic ones (that have multiple meanings), and provide a greater amount of domain information. The tool tags images by first processing all significant wor
15、ds in the text around them, extracting all keywords and key phrases in it, ranking them according to their significance, and linking them to ontological concepts. It generates a set of concept numbers for each text, which is then used to retrieve information in a process called semantic expansion, w
16、here a keyword query is also processed semantically. The proposed approach is illustrated with examples using the tool developed for the needs of Stile Bertone and Fiat, Italy, two of the industrial partners in the TRENDS project sponsored by the European Community.Article Outline1.
