[en] This is the first wall for a fusion reactor, one wall of which is directly exposed to the plasma and whose other wall has cooling devices such as cooling ducts, where the heat is mainly transmitted to the cooling ducts by radiation, and the side of the wall towards the plasma consists of plates next to one another, whose flat surface is turned towards the plasma. The purpose of this invention is to improve such a wall in its thermodynamic properties, on the one hand, and on the other hand, to ensure easy replacement of the elements directly exposed to radiation. This is achieved by the cooled side of the wall having cooling ducts whose walls form rail-like structures, which have narrow places away from the plasma and wider places connected to them. The plates are made of cast blocks whose upper side is flat and turned towards the plasma. The ends of the cast blocks towards the cooled sides have curves whose positive form corresponds to the negative structures between the metal walls. The moulded blocks are threaded one after another in their curves on the rails, where their upper sides next to one another form a surface towards the plasma. (orig.)

[en] GA Technologies Inc. and other U.S. corporations, in a cooperative program with the U.S. Department of Energy, is developing a Modular High-Temperature Gas-Cooled Reactor (MHTGR) that will provide highly reliable, economic, nuclear power. The MHTGR system assures maximum safety to the public, the owner/operator, and the environment. The MHTGR is being designed to meet and exceed rigorous requirements established by the user industry for availability, operation and maintenance, plant investment protection, safety and licensing, siting flexibility and economics. The plant will be equally attractive for deployment and operation in the U.S., other major industrialized nations including Korea, Japan, and the Republic of China, as well as the developing nations. The High-Temperature Gas-Cooled Reactor (HTGR) is an advanced, third generation nuclear power system which incorporates distinctive technical features, including the use of pressurized helium as a coolant, graphite as the moderator and core structural material, and fuel in the form of ceramic coated uranium particles. The modular HTGR builds upon generic gas-cooled reactor experience and specific HTGR programs and projects. The MHTGR offers unique technological features and the opportunity for the cooperative international development of an advanced energy system that will help assure adaquate world energy resources for the future. Such international joint venturing of energy development can offer significant benefits to participating industries and governments and also provides a long term solution to the complex problems of the international balance of payments

[en] CANDU-3 is the latest and smallest Canadian PHWR for electricity generation. Rated at 450 MWe, CANDU-3 offers a highly flexible plant configuration, adaptable to a wide range of different user requirements and sites. Simplified component installation and extensive use of pre-assembled modules has shortened the construction schedule to less than three years. CANDU-3 should have particular appeal to countries without hydro or economic fossil fuel resources, countries with small or subdivided grid systems, and countries wanting to develop a nuclear industry with minimum investment.

[en] Current endeavors in community detection suffer from the resolution limit problem and can be quite expensive for large networks, especially those based on optimization schemes. We propose a conceptually different approach for multi-resolution community detection, by introducing the kernels from statistical literature into the graph, which mimic the node interaction that decays locally with the geodesic distance. The modular structure naturally arises as the patterns inherent in the interaction landscape, which can be easily identified by the hill climbing process. The range of node interaction, and henceforth the resolution of community detection, is controlled via tuning the kernel bandwidth in a systematic way. Our approach is computationally efficient and its effectiveness is demonstrated using both synthetic and real networks with multiscale structures.

[en] The torus of ASDEX Upgrade consists of 8 identical segments ('octants'), which are prefabricated by a special device ('prefabrication stage') and are then assembled later at the place for assembly. An octant consists of one eighth of the vacuum vessel, one eighth (consisting of 4 castings) of the tilting structure and 2 TF coils. After the first measuring work at the place for assembly, the foundations of the TF system are mounted. A spindle lifting device is fitted to these foundations, on which the lower spoked wheel of the PF system is built up in the lowered position. A 16 metre long assembly track is erected above the spoked wheel, on which the torus or parts of it can be moved. Because of the inner stabilising coils (PLS and CoI), it is not possible to build up the torus completely in one operation. Instead, the two halves of the torus are built up separately, so that the halves of the coils can be rotated in. Only then can the two halves of the torus be brought together and connected. The complete torus then has to be moved again, in order to be able to mount the lower annular coils (OHZ, V1, V2, CoA and V3). (orig./GG)

[en] It has been a challenging task to integrate high-throughput data into investigations of the systematic and dynamic organization of biological networks. Here, we presented a simple hierarchical clustering algorithm that goes a long way to achieve this aim. Our method effectively reveals the modular structure of the yeast protein-protein interaction network and distinguishes protein complexes from functional modules by integrating high-throughput protein-protein interaction data with the added subcellular localization and expression profile data. Furthermore, we take advantage of the detected modules to provide a reliably functional context for the uncharacterized components within modules. On the other hand, the integration of various protein-protein association information makes our method robust to false-positives, especially for derived protein complexes. More importantly, this simple method can be extended naturally to other types of data fusion and provides a framework for the study of more comprehensive properties of the biological network and other forms of complex networks

[en] In this article, the author introduces an embedded mini-system module M9080-FNU20, which uses 7 series ARM processor LPC2290 as its core. Based on M9080-FNU20, the author has developed the secondary instrument of passive electronic collection Rn monitor. (authors)

[en] This article is intended to show the important considerations, which led to the development of the multichannel group radiator technique. Trends in development and the advantages and disadvantages of the different possibilities are introduced, against the background of experience now available for these configurative variants of ultrasonic test heads. For this reason, a series of experiences and arguments is reported, from the point of view of the developer of the multi-channel group radiator technique. (orig./HP)

[en] The patent claims a desio.n of a modular steam generator, especially the configuration of the modules. The whole steam generator is placed in an insulation box. The advantage is in that relatively lar.o.e collectors are arranged inside the steam generator assembly. (J.P.)
