in this work‎, ‎we formulate chatterjea contractions using graphs in metric spaces endowed with a graph ‎‎and‏ ‎‎‎‎investigate ‎the ‎existence‎ ‎of ‎fixed ‎points ‎for such mappings ‎under two different hypotheses‎. we also discuss the uniqueness of the fixed point. the given result is a generalization of chatterjea's fixed point theorem from metric spaces to metric spaces endowed with a g...

ÐIn many scientific applications, array redistribution is usually required to enhance data locality and reduce remote memory access in many parallel programs on distributed memory multicomputers. Since the redistribution is performed at runtime, there is a performance trade-off between the efficiency of the new data decomposition for a subsequent phase of an algorithm and the cost of redistribu...

Introduction Peptide mapping is a common technique in the biopharmaceutical industry to characterize monoclonal antibodies (mAbs) for the determination of product identity and stability. Many conventional sample preparation methods are time consuming with digestion times of several hours and can introduce modifications such as deamidation, oxidation, and carbamylation.1 In this study, two class...

This paper presents an overview of advanced bibliometric methods for (1) objective and transparent assessment of strengths and weaknesses in research performance, and (2) monitoring interdisciplinary scientific developments. In the first application, we focus on the detailed analysis of research performance in an international comparative perspective. We demonstrate that advanced bibliometric m...

Data obtained from the scientific experiments are heterogeneous and distributed. They are stored in different file formats so it is difficult to be integrated, analyzed, and processed. The aim of this paper is to propose an ontology dependent approach to transform XML based scientific data description into RDF instances in order to using them as a complete resource on the Semantic Web. The tran...

expensive to provide these maps  with field measurements  therefore  it is better to use new methods. this study provides a lithological and alteration mapping units with dominant minerals based on hyperspectral images of eo1-hyperion satellite. to do so, two different zones  were  investigated:  the  cuprite-nevada  and  mozahem  volcano  in  iran  which  have suitable conditions for our study...

In this paper we analyze the scientific workflow matchmaking problem in Grid environments and combine workflow mapping and scheduling. Based on the characteristics of Grids, a new resource model is proposed. Motivated by the observations that not all jobs can run on all resources and that resource-critical jobs should be considered with their ancestor and descendant jobs when mapping, a novel r...

The technological imperative is changing the field of electrophysiology, and we are currently at a crossroads in complex ablation. The rapid emergence of electroanatomic mapping with multielectrode catheters was spawned out of both intellectual necessity (desire for mechanistic insights into arrhythmias) and clinical necessity (to expedite mapping time). During the 1980s, mapping with single-po...

While tone mapping operation of high dynamic range (HDR) images for realistic display is commonly researched, scientific visualization for analysing scene luminance within HDR image has much less attention from researches. This paper has presented and implemented an approach for the reproduction and visualization of the colour information in HDR images. We attempt several simple colour visualiz...
