In order to simulate the thermoforming of a transparency, constitutive equations are proposed for the nonlinear viscoelastic behaviour of poly(methyl methacrylate) near glass transition temperature, which include large deformations. In a first step, they are fitted on a set of uniaxial tensionrelaxation tests at various strain levels and strain rates. In a second step, their implementation in a...

We report a large-scale coronal wave (so-called “EIT wave”) observed with high cadence by EUVI onboard STEREO in association with the GOES B9.5 flare and double CME event on 19 May 2007. The EUVI instruments provide us with the unprecedented opportunity to study the dynamics of flare/CME associated coronal waves. The coronal wave under study reveals deceleration, indicative of a freely propagat...

Public and private organizations in various areas are setting up digital Information Infrastructures (IIs) for interconnecting government, businesses and citizens. IIs can create value by sharing and integrating data of multiple actors. This can be the basis for value added services and especially collaborations of public and private partners can make IIs thrive. Easier access to integrated ser...

We review the current status of the ’Parker hypothesis’ which suggests that the solar corona is heated by a multitude of small flare-like events called nanoflares. Space-born coronal imagers such as SXT, EIT or TRACE have allowed to test Parker’s hypothesis observationally. Combining the results from different authors it seems that we are close to falsifying the hypothesis, i.e. there are not e...

This article reports a pioneering case study of a crowdsourced law-reform process in Finland. In the crowdsourcing experiment, the public was invited to contribute to the law-reform process by sharing their knowledge and ideas for a better policy. This article introduces a normative design framework of five principles for crowdsourced policymaking: inclusiveness, accountability, transparency, m...

We need to build parsers that are robust in the face of many types of parsing challenges, and evaluate them for the accuracy and transparency of their results, and how well the parser scales up to practically-sized problems. We describe a number of ways to measure accuracy, transparency and scale-up, in the context of evaluating the parser in the Casper system, a tutorial for training customer ...

We theoretically demonstrate the mechanically mediated electromagnetically induced transparency in a two-mode cavity optomechanical system, where two cavity modes are coupled to a common mechanical resonator. When the two cavity modes are driven on their respective red sidebands by two pump beams, a transparency window appears in the probe transmission spectrum due to destructive interference. ...

Naming transparencies, i.e., abstracting the name and binding of the entity being used from the endpoints that are actually doing the work, are used in distributed systems to simplify application development by hiding the complexity of the environment. In this paper we demonstrate how to apply traditional distributed systems naming and binding techniques in the Web Services realm. Specifically,...
