Early in World War II, a new map paper was developed that greatly improved the quality and performance of war maps. The National Bureau of Standards cooperated in the development and, subsequently, determined by experimental manufacture how to make the paper from commercially available raw materials. The best results were obtained in experimental manufacture by using fiber furnishes of 100-perc...

Paper maps and mobile electronic devices have complementary strengths and shortcomings in outdoor use. In many scenarios like small craft sailing or cross-country trekking a complete replacements of maps is neither useful nor desirable. Paper maps are failsafe, relatively cheap, offer superior resolution and provide large scale overview. In uses like open-water sailing it is therefore mandatory...

In this paper, we introduce a cone generalized semi-cyclicφ−contraction maps and prove best proximity points theorems for such mapsin cone metric spaces. Also, we study existence and convergence results ofbest proximity points of such maps in normal cone metric spaces. Our resultsgeneralize some results on the topic.

This paper is about concept maps and how they can assist in the learning ofconcepts of mathematics. First the paper presents the theoretical backgroundand working denitions for concept maps. Then this study examines the impactof using concept maps in learning of fractions. Results of this study indicatedthat using this strategy was eective in learning of fractions for fourth-gradestudents. This...

in this paper, we give a characterization of strongly jordan zero-product preserving maps on normed algebras as a generalization of  jordan zero-product preserving maps. in this direction, we give some illustrative examples to show that the notions of strongly zero-product preserving maps and strongly jordan zero-product preserving maps are completely different. also, we prove that the direct p...
