1.1. Antecedents. In virtually all known applications of the Ricci flow, it is valuable to have a good understanding of singularity formation. Heuristically, there are at least three reasons for this. The first is that one expects finite-time singularities to form for a broad spectrum of initial data. Indeed, such singularities are inevitable if the scalar curvature is strictly positive. The se...

one of the by-products of globalization is the need of english spread as a lingua franca. according to the linguistic relativism and world englishes theories, one expects then, a certain proportion of anglo-american cultural values and viewpoints will be projected to the outer circle societies. while this transmission could enhance the cultural quotient (cq) of the learners, it can also bear ne...

The actual class for a component’s import is not determined until component link time. Nevertheless, Jiazzi supports separate compilation (and type checking) of components and type-safe linking. To maximize flexibility, Jiazzi allows mutually recursive components, and allows the actual class supplied for a component’s import to provide more methods then the component expects. Potential problems...

They also tried something new this year: short papers that are refereed the same way as longer papers. Bill then showed an image representing the words found in paper subjects and abstracts. Obvious words, such as “storage” and “system,” were most prominent, followed by “file,” “data,” “deduplication,” “flash,” and “performance” (approximately—check out the video). “Cloud” is still a tiny word,...

naturally associate with computers. Yet over the last few years there has been a surge of research efforts concerning the combination of both subjects. This article tries to shed light on these efforts. In carrying out this program, one is handicapped by the fact that, as words, both creativity and storytelling are severely lacking in the precision one expects of words to be used for intellectu...

Multi stakeholder distributed systems become more and more widespread and raise a lot of integration problems. One problem is that conflicts arise often only at runtime if a single system component is changed. The whole composition of systems then doesn’t behave like at least one of the stakeholders expects. The following paper provides a classification of the potential conflicts and gives some...

This paper attempts to explore a new method to improve the teaching of computer programming for beginners at tertiary level. It begins with a change of approach to teaching and then to a mix of basic theory and practice. It then finds a core language, which simplified the scope of programme design and implementation. Dynamic visualisation technique was used as a supplementary tool in programme ...
