The EU project ALVIS - Superpeer Semantic Search Engine, aiming at developing an Open Source prototype of a peer-to-peer, semantic based search engine, is brie°y presented. A focused (or topic speci¯c) crawler, responsible for creating topic-speci¯c databases within ALVIS, is presented in more detail. It is based on a combination of a standard Web crawler and an automated subject classi¯er. The to
Communication over the copper twisted-pair channel is performed by transmitting and receiving differential-mode (DM) signals. In this paper, we extend the conventional DM receive scheme by incorporating the common-mode (CM) signal, which can be extracted at the end of every wire pair. We assess the potential of this idea for digital subscriber line systems (xDSL) in terms of channel capacity using
Differences in national legislations can affect the international competitiveness of an industry. For example, stringent EU regulations on animal welfare and environmental protection are often said to be a cost disadvantage for EU producers competing on the global market. However, in recent years, powerful retailers and food processors have started to impose requirements on downstream producers th

High-speed laser diagnostics was utilized for single-cycle resolved studies of the fuel distribution in the combustion chamber of a truck-size HCCI engine. A multi-YAG laser system consisting of four individual Nd:YAG lasers was used for planar laser-induced fluorescence (PLIF) imaging of the fuel distribution. The fundamental beam from the lasers at 1064 nm was frequency quadrupled in order to ob
Drawing upon a discourse analysis of policy approach, it is shown that a 2013 Swedish government policy proposing semiprivatization of universities is not a radical departure from Swedish social democratic values about public institutions, but rather the current iteration of a longer neoliberal semiotic cycle in higher education.
This study examines the characteristics and nature of rumor via mobile communication in contemporary China. By focusing on six concrete case studies with 50+ in-depth interviews, this study observes that mobile phone-mediated rumor has evolved into a special form of popular resistance at the grassroots level. The low-cost and user-friendly mobile device lowers the average protest threshold, creati
