Deploying lightweight tasks individually on grid resources would lead to a situation where communication overhead dominates the overall application processing time. The communication overhead can be reduced if we group the lightweight tasks at the meta-scheduler before the deployment. However, there is a necessity to limit the number of tasks in a group in(More)
Recognition of primitives in technical drawings is the first stage in their higher level interpretation. It calls for processing of voluminous scanned raster files. This is a difficult task if each pixel must be addressed at least once, as required by Hough transform or thinning-based methods. This work presents a set of algorithms that recognize drawing(More)
 An unorganized deployment of grid applications with a large amount of fine-grain jobs would let the communication overhead dominate the overall processing time, resulting in a low computation-communication ratio. Grid's dynamic nature complicates the planning of the job scheduling activity for minimizing the application processing time. This paper(More)
Deploying lightweight tasks on grid resources would let the communication overhead dominate the overall application processing time. Our aim is to increase the resulting computation-communication ratio by adjusting the task granularity at the grid scheduler. We propose an on-line scheduling algorithm which performs task grouping to support an unlimited(More)
With the wide availability of chip multi-processing (CMP), software developers are now facing the task of effectively parallelizing their software code. Once they have identified the areas of parallelization, they will need to know the level of code granularity needed to ensure profitable execution. Furthermore, this problem multiplies itself with different(More)
— The overhead of processing fine-grain tasks on a grid induces the need for batch processing or task group deployment in order to minimise overall application turnaround time. When deciding the granularity of a batch, the processing requirements of each task should be considered as well as the utilisation constraints of the interconnecting network and the(More)
Frameworks are increasingly employed as a useful way to enable object-oriented reuse. However, their size and complexity make understanding how to use them difficult. Previous work concentrated on different ways to document frameworks, but it was unclear which ones actually were better. This paper presents a novel way of investigating the sequences of three(More)
The revolutionary integration of Near Field Communication (NFC) into smartphones has radically enabled new participatory learning applications between objects and the mobile phones. NFC-enabled smartphone technology can be used as a springboard to fuel mobiquitous learning applications that could potentially change the students' digital learning lifestyle,(More)
Overhead of executing fine-grain tasks on computational grids led to task group or batch deployment in which a batch is resized according to the characteristics of the tasks, designated resource, and the interconnecting network. An economic grid demands an application to be processed within the given budget and deadline, referred to as the quality of(More)
Grid computing technology is a new field which focuses on large-scale resource sharing. The grid concept is coordinated resource sharing and problem solving in dynamic, multi-institutional virtual organizations (VO). In this dynamic and geographically dispersed setting, information services are regarded as a vital component of the grid infrastructure. Grid(More)
