The Baptista cryptosystem uses the logistic map to generate chaotic sequence. The encryption process of a given plaintext character consists of iterating the chaotic map until the state reaches the subinterval assigned to that symbol. The cipher text corresponding to the plaintext symbol is the number of iterations in the chaotic map. We propose a method to enhance the security and compression ...

constructionof underground dams is a practical solution to save groundwater in alluvium watersheds, particularly in arid and semi-arid regions where surface water scarcity is an environmental challenge. considering socio-economic and environmental benefits of underground dams, the accurate locating is the primary consideration for dam construction. the new technologies and methods are a step to...

The Semantic Web would enable new ways of doing business on the Web that require development of advanced business document integration technologies performing intelligent document transformation. The documents use different vocabularies that consist of large hierarchies of terms. Accordingly, vocabulary mapping and transformation becomes an important task in the whole business document transfor...

The selection of map projections is difficult and confusing for many. This article introduces Projection Wizard, an online map projection selection tool available at projectionwizard.org that helps mapmakers select projections. The user selects the desired distortion property, and the area to be mapped on an interactive web map. Projection Wizard then proposes a projection, along with projectio...

Image segmentation process for high quality visual saliency map is very dependent on the existing visual saliency metrics. It is mostly only get sketchy effect of saliency map, and roughly based visual saliency map will affect the image segmentation results. The paper had presented the randomized visual saliency detection algorithm. The randomized visual saliency detection method can quickly ge...

This paper discusses the process of identifying stakeholders for the evaluation of health information systems through a map. Defining the multiplicity of stakeholders associated with a new system as well as the nature of their relationships is an important aspect of evaluating any intervention. We report a study of the Electronic Prescription Service (EPS) in primary care in England. We describ...

This paper present a novel Dynamic Enactment Support to Specify and Execute Methods with the process model called Map. Maps describe the intentions that can be achieved in a process, strategies to achieve these intentions, and possible orders of intention achievements. When the user has selected the intention he wants to achieve along with the strategy he wants to use, the corresponding method ...

The technique of simultaneous localization and mapping is the most important research topic in mobile robotics. In the process of building a map in its available memory, the robot memorizes environmental information on the plane of grid or topology. Several approaches about this technique have been presented so far, but most of them use mapping technique as either grid-based map or topology-bas...
