The application of methods from multidimensional systems theory and digital signal processing opens new ways for the eecient simulation of time and space dependent problems like wave propagation or heat and mass transfer. The basic idea is the application of suitably chosen functional transformations for the time and space coordinates. Initial and boundary conditions are considered in a systema...

Currently, most of distance learning courses can only deliver standard material to students. Students receive course content passively which leads to the neglect of the goal of education – “to suit the teaching to the ability of students”. Providing appropriate course content according to students’ ability is the main goal of this paper. Except offering a series of conventional learning service...

In this paper we address an issue common in the frame of WWW namely information entities that present di erent facets under di erent contexts or worlds Handling such multifacet or multidimen sional entities requires a multidimensional paradigm for Web data which consists of representation manipulation and presentation issues For rep resenting multidimensional data we employ Multidimensional XML...

Adaptive hypermedia techniques provide users with personalisation of contents and links. Some of the criticisms of adaptive systems are that users do not always understand why the system is adapting the content and links [14], and that the adaptation process can lead to prolific or out of place linking. This paper introduces the concept of a multi-dimensional linkbase to describe a single linkb...

Nature ofphysical problem A lot of problems in physics, chemistry, applied mathematics as well as in engineering and in other fields, are quite often reduced tominimizing a function of several variables. MERLIN is a system designed to minimize a multidimensional function. Method of solution Six algorithms are implemented. Three of them make use of the function’s gradient and hence are suitable ...

In this paper, we present a kind of airborne multidimensional integrated remote sensing system that consists of an imaging spectrometer, a three-line scanner, a laser ranger, a position & orientation subsystem and a stabilizer PAV30. The imaging spectrometer is composed of two sets of identical push-broom high spectral imager with a field of view of 22°, which provides a field of view of 42°. T...

This paper presents multidimensional aggregation query processing algorithm in cloud computing system. The existing cloud computing research work in the MapReduce calculation framework lacks effective support to the aggregation of multi-dimensional data. On the other hand, the use of MapReduce computing framework needs to start large computing nodes, and costs huge amounts of energy. For the ab...

We have defined a model for multidimensional hyperpresentations, in which time-varying multimedia presentations are dynamically linked together. In our model a hyperlink’s context can change over time. Thus, at any time during a continuous presentation, a user can interactively access context-specific information. How the hyperlinks are traversed depends upon user interaction and/or context-sen...
