GRB941017, a gamma-ray burst of exceptional fluence, has recently been shown to have a high-energy component which is not consistent with the standard fireball phenomenology. If this component is the result of photomeson interactions in the burst fireball, it provides new and compelling support for substantial high-energy neutrino fluxes from this and similar sources. In this letter, we conside...

Based on a 3-year ethnographical study, this paper discusses the prolonged use of Computer-Mediated Communication (CMC) tools by approximately 400 older people in an adult education centre in Barcelona (Spain). Contrary to oversimplified views of older people as ICT users, this paper shows that they make a very rich use of CMC tools. Relevant elements of this use are their permanent desire to f...

In this paper we have studied the effect of magneto-static field onpropagation of thermal wave generated in metal by pulsed laser. In fact this interactiongenerate acoustic wave in different mechanisms. However, always the commonmechanism in the interactions of laser pulse and metal is the thermo-elastic wavegeneration. Applying the suitable magneto-static field on the s...

Generation mean analysis was carried out to estimate the nature andmagnitude of gene effects for sugar yield and its component traits in sweet sorghum[Sorghum bicolor (L.) Moench. Six basic generations, namely P1, P2, F1, F2,BC1P1, BC1P2 of four crosses involving seven diverse parents were evaluated inrainy 2009. The mean performance of the F1 in all the crosses indicated dominantgene effect fo...

When people interact with language-producing agents (other people or computers), they assume that the shared experience leads to shared representations – of the world, the interaction, and the language used in the interaction. This phenomenon occurs even during interaction with systems that give no evidence of building shared representations. The absence of shared representations leads to error...

Deciding on the complexity of a generated text in NLG systems is a contentious task. Some systems propose the generation of simple text for low-skilled readers; some choose what they anticipate to be a “good measure” of complexity by balancing sentence length and number of sentences (using scales such as the D-level sentence complexity) for the text; while others target high-skilled readers. In...

When are economic interactions mediated by prices and transfers, and when are they mediated by variations in the continuation payoffs within a relationship? To address this question, we examine a relationship between two players who periodically face opportunities to undertake randomly generated “projects” that impose a cost on one player and a benefit on the other, as well as opportunities to ...

In text, discourse markers signal the kind of coherence relation holding between adjacent text spans; for example, because, since; and for this reason are different markers for causal relations. Fo r any but the most simple applications of text generation, marker Selection is an important aspect of producing cohesive text. However, present systems use markers in fairly simplistic ways andcannot...

This paper analyses responses of ninety-nine students to a design brief for a public building in different regions of China. The research determined the level of understanding and skills development in students who will be the next generation of building designers, procurers and developers. The students were asked to design in a bioclimatic fashion and therefore to consider the building to be a...
