    We present an interactivity demonstration of Expressy. A system that augments existing touchscreen devices with a variety of continuous expressive interaction capabilities, using movement data from a wrist-worn IMU. Our demonstration comprises a set of applications that show how the expressive touch interaction capabilities, offered by Expressy, can enable intuitive and meaningful interactions, in contexts including productivity, entertainment and lifestyle apps. This demo submission accompanies a full paper, describing a conceptual model of expressive touch interaction and the implementation and evaluation of Expressy. © 2016 Authors

    Additions of lactams, imides, (S)-4-benzyl-1,3-oxazolidin-2-one, 2-pyridone, pyrimidine-2,4-diones (AZT derivatives), or inosines to the electron-deficient triple bonds of methyl propynoate, tert-butyl propynoate, 3-butyn-2-one, N-propynoylmorpholine, or N-methoxy-N-methylpropynamide in the presence of many potential catalysts were examined. DABCO and, second, DMAP appeared to be the best (highest reaction rates and E/Z ratios), while RuCl3, RuClCp*(PPh3)2, AuCl, AuCl(PPh3), CuI, and Cu2(OTf)2 were incapable of catalyzing such additions. The groups incorporated (for example, the 2-(methoxycarbonyl)ethenyl group that we name MocVinyl) serve as protecting groups for the above-mentioned heterocyclic CONH or CONHCO moieties. Deprotections were accomplished via exchange with good nucleophiles: the 1-dodecanethiolate anion turned out to be the most general and efficient reagent, but in some particular cases other nucleophiles also worked (e.g., MocVinyl-inosines can be cleaved with succinimide anion). Some structural and mechanistic details have been accounted for with the help of DFT and MP2 calculations

    Developing a quality costing system: Key features and outcomes

    This paper discusses the development and operation of a system of quality costing in a manufacturer of coatings for industrial applications. The work reported is of particular value since most of the well-publicised material on quality costing is in relation to mechanical and electrical engineering type situations. Attention is drawn to the difficulties encountered in establishing the system, including the adaptions and additions needed to the cost elements which had been identified from the quality costing literature, deciding what was a quality-related cost, determining the reporting format for quality costs, the elimination of double counting, and dealing with the operating practices of accountants. The collection, reporting and uses of quality cost data are also examined. It is also pointed out that many of the practical findings support much of the quality costing theory.quality costing coatings manufacture quality cost collection quality cost reporting quality cost uses
