The COST 249 SpeechDat reference recogniser is a fully automatic, language-independent training procedure for building a phonetic recogniser. It relies on the HTK toolkit and a SpeechDat(II) compatible database. The recogniser is designed to serve as a reference system in multilingual recognition research. This paper documents version 0.93 of the reference recogniser and presents results on sma...

This vignette demonstrates how to use the Structural Topic Model, stm, R package. The Structural Topic Model (STM) allows researchers to estimate a topic model which includes document-level meta-data. The stm package provides a range of features from model selection to extensive plotting and visualization options.

The regularized expectation value of the stress-energy tensor for a massless bosonic or fermionic field in 1+1 dimensions is calculated explicitly for the instantaneous vacuum relative to any Cauchy surface (here a spacelike curve) in terms of the length L of the curve (if closed), the local extrinsic curvature K of the curve, its derivative K ′ with respect to proper distance x along the curve...

This paper addresses the problem of automatic speech recognition in the presence of interfering noise. It focuses on the Parallel Model Combination (PMC) scheme, which has been shown to be a powerful technique for achieving noise robustness. Most experiments reported on PMC to date have been on small, 10-50 word vocabulary systems. Experiments on the Resource Management (RM) database, a 1000 wo...

Flow, the concept developed by Mihaly Csikszentmihalyi over the last forty years or so (see Csikszentmihalyi 1975) has been invoked quite often with respect to the way players engage with digital games (e.g. Baron 2012; Cowley et al. 2008; Sweetser and Wyeth 2005; Brathwaite & Schreiber, 2009; Fullerton, Swain, & Hoffman, 2008; Schell, 2008). However Kubey & Csikszentmihalyi (2002) argue that ‘...

Open source communities evolve. This evolution is, at times, driven by corporate engagement with those communities. In these corporate-communal contexts, open source foundations often serve as facilitators in the evolution process and make these arrangements more stable over time. This paper expands the application of complex adaptive systems (CAS) theory to understand the role of open source f...

Scripting languages like Python, R, and MATLAB have seen significant use across a variety of scientific domains. To assist scientists in the analysis of script executions, a number of mechanisms, e.g., noWorkflow, have been recently proposed to capture the provenance of script executions. The provenance information recorded can be used, e.g., to trace the lineage of a particular result by ident...

MOTIVATION spacodiR is a cross-platform package, written for the R environment, for studying partitioning of diversity among natural communities in space and time. Complementing and extending existing software, spacodiR allows for hypothesis testing and parameter estimation in studying spatial structuring of species-, phylogenetic- and trait diversities. AVAILABILITY Integrated with other sof...

As the leading vendor of enterprise business standard software, SAP has recognized the need to adapt their R/3 system to current trends in software development and to meet market needs for speed of development, flexibility, openness and interoperability. In this paper, we first present SAP’s approach to object-oriented and componentbased technology by describing the Business Framework, the conc...
