A system for the acquisition, storage, indexing, and retrieval of map images is presented. The input to this system are raster images of separate map layers and map composites. A legend driven map interpretation system converts layer images from a physical to a logical representation. This logical representation is used to automatically index both the composite and the layer images. Methods for...

We present TopoVW, an efficient heuristic for map simplification that deals with a variation of the generalization problem where the idea is to simplify the polylines of a map without changing the topological relationships between these polylines or between the lines and control points. This process is important for maintaining clarity of cartographic data, avoiding situations such as high dens...

We propose a three step iterative and interactive visual text mining process to assist users in exploring document collections. In the proposed approach (i) topics are automatically extracted from a document collection , (ii) users explore a similarity-based document map and its related topics, while refining a topic list, and (iii) map quality itself and topic list definition can both be impro...

Along with the rapid advances of the nextgen sequencing technologies, more and more species are added to the list of organisms whose whole genomes are sequenced. However, the assembled draft genome of many organisms consists of numerous small contigs, due to the short length of the reads generated by nextgen sequencing platforms. In order to improve the assembly and bring the genome contigs tog...

The purpose of this study is to explore how concept map formation process carried out by individuals who are designated experts and novices. As a group of novice participants, 73 prospective teachers and 5 experts were participated to the study. Data collected by using open ended questionnaires, and retrospective review and eye tracking sessions. These data were used to explore the cognitive pr...

The first objective in any financial organization is to improve performance, and performance evaluation also is one of the best ways to advance operations in organizations. By utilizing different methods of performance evaluation, organizations can evaluate the effectiveness and efficiency of processes that are in accord with strategic objectives. In addition, the performance evaluation instrum...

Since the advent of evolution strategies many attempts have been done to improve the mutation operator [7]. The first enhancement could be seen in the introduction of a flexible step size. As a logical consequence later n step sizes, one per variable, were used. Highest flexibility is achieved with the correlated mutation but also quadratic growth of the number of strategy parameters [8]. A new...

In order to reduce the risk of complete failure, research managers often adopt a parallel strategy by simultaneously funding several R&D activities and several research teams within each activity. The parallel strategy requires the allocation of an available budget to a number of R&D activities, the determination of the number of research teams within each activity and the amount of funding the...
