Visual notations are a key aspect of visual languages. They provide a direct mapping between the intended information and set of graphical symbols. Visual no-tations are most often implemented using the low level syntax of programming languages which is time con-suming, error prone, difficult to maintain and hardly human-centric. In this paper we describe an alterna-tive approach to generating visual notations using by-example model transformations. In our new approach, a semantic mapping between model and view is imple-mented using model transformations. The notations resulting from this approach can be reused by map-ping varieties of input data to their model and can be composed into different visualisations. Our approach is implemented in the CONVErT framework and has been applied to many visualisation examples. Two case studies for visualising statistical charts and visualisa-tion of traffic data are presented in this paper. A de-tailed user study of our approach for reusing notations and generating visualisations has been provided that shows good reusability and general acceptance of the novel approach.

Number 841 Computer Laboratory Information centric delay tolerant networking: an internet architecture for the challenged

Content-Type: text/plain

There is widespread agreement on the need for architectural change in the Internet, but very few believe that current ISPs will ever effect such changes. In this paper we ask what makes an architecture evolvable, by which we mean capable of gradual change led by the incumbent providers

The NEBULA Future Internet Architecture (FIA) project is focused on a future network that enables the vision of cloud computing [8,12] to be realized. With computation and storage moving to data centers, networking to these data centers must be several orders of magnitude more resilient for some

We propose a new design for highly concurrent Internet services, whichwe call the staged event-driven architecture (SEDA). SEDA is intended

The highly successful architecture and protocols of today’s Internet may operate poorly in environments characterized by very long delay paths and frequent network partitions. These problems are exacerbated by end nodes with limited power or memory resources. Often deployed in mobile and extreme

ABSTRACT We examine how to re-design the Internet for an energyconstrained future powered by diffuse, intermittent, and expensive power sources. We consider the types of constraints this might place upon the Internet architecture and the manner in which important network components can function
