ISO 13407 standard [1] defines a set of User-Centered Design (UCD) activities and principles through which usable systems can be developed. Still there exist quite a few organizations, which systematically and consciously apply UCD in their product development. Usability capability is a characteristic of a development organization that determines its ability to constantly develop products with ...

To improve the agility, dynamics, composability, reusability, and development efficiency restricted by monolithic Federation Object Model (FOM), a modular FOM was proposed by High Level Architecture (HLA) Evolved product development group. This paper reviews the state-of-the-art of HLA Evolved modular FOM. In particular, related concepts, the overall impact on HLA standards, extension principle...

A new type of per-fluorinated polymer, "Low Temperature Fomblin," has been tested as a wall coating in an ultracold neutron (UCN) storage experiment using a gravitational storage system. The data show a UCN reflection loss coefficient η as low as ≈ 5 × 10(-6) in the temperature range 105 K to 150 K. We plan to use this oil in a new type of neutron lifetime measurement, where a bellows system ("...

We present Andante, a representation of music as animated characters walking along the piano keyboard that appear to play the physical keys with each step. Based on a view of music pedagogy that emphasizes expressive, full-body communication early in the learning process, Andante promotes an understanding of music rooted in the body, taking advantage of walking as one of the most fundamental hu...

Broad hydroxyl (OH) absorption-lines in the 1667 MHz and 1665 MHz transition towards the central region of NGC3079 have been observed at high resolution with the European VLBI Network (EVN). Velocity fields of two OH absorption components were resolved across the unresolved nuclear radio continuum of ∼ 10 parsecs. The velocity field of the OH absorption close to the systemic velocity shows rota...

We study the magnitude and persistence of the diffusion of exogenous demand shocks on an ecommerce recommendation network. The demand shocks are generated by book reviews on the Oprah Winfrey Show and in the NYTimes, and the recommendation network is generated by Amazon’s copurchase network. We find a strikingly high level of diffusion of exogenous shock through such networks. Neighboring books...

-Railway signal system requires the high level of safety in order to safeguard safe operation of the train and people’s lives, so the risk analysis of railway signal system counts for much. However, due to the incomplete of the risk data, it is often impossible to obtain a satisfactory result. This article presents a comprehensive study in the risk analysis model of railway signal system on saf...

This paper describes two recent improvisation systems that incorporate timbre as an integral element in performance characterization and decision-making. The first London system uses high-level performance descriptors, adapted from recent work in mood detection in music, to coordinate low-level performance events. It was used in performances at LAM 2006 and NIME 2007. After careful evaluation o...

We imagine a coalescent process as modelling the genealogy of a sample from a population which is subject to neutral mutation. We work under the assumptions of the infinitely many alleles model so that, in particular, every mutation gives rise to a completely new type in the population. Mutations occur as a Poisson process of rate ρ along the branches of the coalescent tree. The allelic partiti...

We report on the 0.1–100 keV BeppoSAX observations of two nearby LINER galaxies, Sombrero and NGC 4736. Chandra ACIS-S observations supplement this broad-beam spectral study with a high resolution look into the nuclear region, and show a dominating central point source in Sombrero and a complex X-ray binary dominated/starburst region in NGC 4736. A compact non-thermal radio source, present in t...
