Stay unpopular-and get rich quick
No full textIt is now widely understood that the only way to increase your winnings in the national lottery is to pick an unpopular set of numbers. Jill Papworth's article (Lucky Break? Don’t leave it to chance, January 27) discusses a few ideas for this. Back in 1998, we used a statistical method, first developed for radio astronomy, and a prototype Windows supercomputer, to analyse the winners in the first two years of the lottery. It gave us surprisingly detailed information about unpopular tickets and attracted academic and press interest. We found the best ticket to be 26, 34, 44, 46, 47, 49—but not if you all follow this advice! Overall, 1, 34, 40, 41, 43, 45, 46, 47 and 49 were all good numbers

New Schools in the East and west of Southampton
No full textThe City Council is currently deciding a competition between bidders vying to run two new secondary schools which will replace Grove Park, Millbrook, Oaklands and Woolston schools. It is a rather sad story and I would counsel against two pairs of proposals, those from the Southampton Education Trust and from the United Learning Trust. I would also suggest caution over the bids from Oasis Community Learning, although I believe they are unambiguously the best on offer
SCOTT: The Southampton COFF Tools for Transputers
No full textWe have built a software development toolset fot T800 and T9000 series transputers suitable for compilers, including ACE eXpert and gcc implementations, using the COFF object format. Our toolset includes a bootstrap, loading and configuration environment, an interactive debugger and implementations of the PVM and MPI message-passing environments. The tcl scripting language is extensively used
UNICORE and GRIP: experiences of grid middleware development
No full textWe describe our experiences with the UNICORE Grid environment. Several lessons of general applicability can be drawn in regard to user uptake and security. The principal lesson is that more effort should be taken to be made to meet the needs of the target user community of the middleware development. Novel workflow strategies, in particular, should not be imposed on an existing community
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Semantically Resolving Type Mismatches in Scientific Workflows
No full textScientists are increasingly utilizing Grids to manage large data sets and execute scientific experiments on distributed resources. Scientific workflows are used as means for modeling and enacting scientific experiments. Windows Workflow Foundation (WF) is a major component of Microsoft’s .NET technology which offers lightweight support for long-running workflows. It provides a comfortable graphical and programmatic environment for the development of extended BPEL-style workflows. WF’s visual features ease the syntactic composition of Web services into scientific workflows but do nothing to assure that information passed between services has consistent semantic types or representations or that deviant flows, errors and compensations are handled meaningfully. In this paper we introduce SAWSDL-compliant annotations for WF and use them with a semantic reasoner to guarantee semantic type correctness in scientific workflows. Examples from bioinformatics are presented
