Modern datastream management system (DSMS) assume sensor measurements to be constant valued until an update is measured. They do not consider continuously changing measurement values, although a lot of real world scenarios exist that need this essential property. For instance, modern cars use sensors, like radar, to periodically detect dynamic objects like other vehicles. The state of these obj...

[1] Understanding the mechanisms governing temporal variability of ice stream flow remains one of the major barriers to developing accurate models of ice sheet dynamics and ice-climate interactions. Here we analyze a simple model of ice stream hydrology coupled to ice flow dynamics and including drainage and basal cooling processes. Analytic and numerical results from this model indicate that t...

Until recently, the study of writing systems was something of a Cinderella subject within the discipline of linguistics. For a long time there was only one standard monograph, I.J. Gelb’s 1952 book A Study of Writing, which was valuable but was little influenced by the insights of modern structural linguistics. Many linguists saw human language as a window onto biologically-determined structure...

When writing can change your life, when writing can enrich you by offering much money, why don't you try it? Are you still very confused of where getting the ideas? Do you still have no idea with what you are going to write? Now, you will need reading. A good writer is a good reader at once. You can define how you write depending on what books to read. This modern database systems the object mo...

Sustainable development is a popular phrase often associated with environmental studies, but the phrase can serve as ecological metaphor through which to view environments associated with writing assessment and writing program development. Sustainable environments depend on symbiotic relationships. Writing assessment and writing program development constantly rely on the classroom environment a...

The medical writings of early medieval western Europe c. 700 – c. 1000 have often been derided for their disorganised appearance, poor Latin, nebulous conceptual framework, admixtures of magic and folklore, and general lack of those positive features that historians attribute to ancient or later medieval medicine. This paper attempts to rescue the period from its negative image. It examines a n...

Stencil computations are at the core of applications in many domains such as computational electromagnetics, image processing, and partial differential equation solvers used in a variety of scientific and engineering applications. Short-vector SIMD instruction sets such as SSE and VMX provide a promising and widely available avenue for enhancing performance on modern processors. However a funda...
